Early diagnosis and treatment can prevent serious complications and disability, reducing the risk of avascular necrosis of the humeral head and joint destruction. Several treatment options have been proposed, depending on the patient’s age, duration of dislocation, humeral head bone defect, length of the metaphysis attached to the reverse Hill-Sachs, osteopenia and functional demand, and concomitant diseases. Open anatomic reduction and internal fixation is a suitable option, particularly in young and active individuals. Humeral joint replacement is recommended for non-fixable 3- or 4-part fractures, particularly in elderly individuals with low demand and osteoporosis. This article reports a case of closed, irreducible PSFD that was treated with open reduction and internal fixation using a plate and deltopectoral approach.

This study aimed to evaluate the clinical and laboratory manifestations and treatment outcomes of patients with liver cirrhosis who were infected with COVID-19.
Methods: This retrospective descriptive study was conducted on 9 patients (4 women and 5 men) with liver cirrhosis infected with COVID-19 hospitalized at Shahid Sayyad Shirazi Educational and Therapeutic Center in Gorgan, Iran during 2019-20. COVID-19 infection was diagnosed by a positive polymerase chain reaction (PCR) test. The Child-Pugh score was used to classify the severity of liver disease. Demographic and clinical data, including initial symptoms and complaints, laboratory results, need for intensive care unit (ICU) admission, length of hospital stay, and treatment outcomes, were extracted from patients’ medical records.
Results: The severity of liver disease was classified as Class B in 7 patients. Comorbidities included cardiovascular diseases and hypertension in 2 patients each, as well as diabetes and asthma in one patient each. Clinical manifestations at the time of COVID-19 diagnosis included ascites in 6 patients; fever in 5 patients; respiratory distress and anorexia in 4 patients each; cough, oxygen saturation less than 93%, and muscle pain in 3 patients each; nausea and vomiting in 2 patients; and abdominal pain and decreased level of consciousness in one patient each. Albumin levels were less than 4 g/dL in all patients. Hemoglobin was less than 12 g/dL in 7 patients. Thrombocytopenia was observed in 8 patients, leukocytosis in one patient, and leukopenia and pancytopenia in 4 patients each. Alanine transaminase (ALT) and aspartate transaminase (AST) levels were higher than 40 U/L in 6 and 5 patients, respectively. Only one patient died, a 60-year-old woman with a history of fatty liver disease, cardiovascular disease, and uncontrolled Class C cirrhosis.
Conclusion: The most common clinical manifestations in patients with liver cirrhosis infected with COVID-19 consisted of ascites, fever, respiratory distress, and anorexia, and the most common laboratory manifestations were hypoalbuminemia and thrombocytopenia.

The use of parasites or parasite antigens is one of the newest therapeutic approaches for cancer, although it has not yet been used or approved in human trials. This study aimed to determine the cytotoxic effects of purified carbohydrates from the hyaline layer, fluid, and protoscolices of hydatid cysts on the human colorectal cancer cell line (LS174T).
Methods: This descriptive-analytical study was conducted on two sheep and two cow livers infected with hydatid cysts, and the human colorectal adenocarcinoma cell line (LS174T) purchased from the Pasteur Institute of Iran at the Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Iran during 2022. Cyst fluid, protoscolices, and the hyaline layer were isolated from the hydatid cyst-infected livers, and glycoproteins and glycolipids from different parts of the cyst were extracted using the chloroform-methanol method. Carbohydrates were purified using the beta-elimination method and their presence was confirmed using the phenol-sulfuric acid method. The cytotoxicity of purified carbohydrates on the LS174T cell line was evaluated using the methyl tetrazolium (MTT) assay for 24 hours.
Results: Concentrations of 0.5 and 0.25 of purified carbohydrates from glycoproteins and glycolipids of hydatid cysts significantly inhibited the growth of LS174T cells (P<0.05). Initial cytotoxicity evaluation showed that purified carbohydrates from glycoproteins of sheep cyst fluid (38.60±1.33%), glycoproteins of cow cyst hyaline layer (36.61±1.76%), glycolipids of cow cyst hyaline layer (38.94±2.99%), glycoproteins of cow cyst protoscolices (40.27±3.66%), and glycolipids of sheep cyst protoscolices (37.94±1.99%) had significantly more pronounced inhibitory effects (P<0.05). Subsequent screening with the MTT assay revealed that purified carbohydrates from glycoproteins isolated from sheep hydatid cyst fluid (52.35±10.24%), glycolipids isolated from cow hydatid cyst hyaline layer (53.40±7.88%), and glycolipids isolated from sheep hydatid cyst protoscolices (53.05±5.06%) had significantly more pronounced inhibitory effects on the growth of LS174T cancer cells (P<0.05).
Conclusion: Carbohydrates isolated from glycoproteins and glycolipids of the hyaline layer, fluid, and protoscolices of hydatid cysts have significant anticancer effects on the LS174T colorectal cancer cell line.

Neoadjuvant chemotherapy (NAC) is one of the treatment methods to improve patient survival. This study aimed to determine the response rate to NAC in patients with locally advanced breast cancer based on common molecular receptors.
Methods: This descriptive-analytical study was conducted on 100 patients with breast cancer (mean age= 41.14±10.06 years) referring to the surgical clinic of the Fifth Azar Educational and Therapeutic Center in Gorgan, Iran during 2013-18. Patients without distant metastasis underwent NAC treatment regimen followed by surgery. Demographic characteristics, types of drugs, and molecular receptor characteristics, and their response to treatment were recorded in a checklist. Treatment response and overall patient survival were evaluated.
Results: The mean tumor size before NAC was 3.01±2.47 cm (range= 0-8, median= 2) and 16% were determined to be grade one, 52% were determined to be grade 2, and 32% were determined to be grade 3. Thirty-six percent of patients had a positive family history. Forty-six percent were estrogen receptor (ER) positive, 40% were PR positive, 22% were human epidermal growth factor receptor 2 (Her-2) positive, and 78% were Her-2 negative. Thirty-six percent had a Ki-67 index greater than 30%. Eighteen percent of patients had a complete pathological response, and 82% had a partial or negative response. In terms of family history of breast cancer, Her2, ER, progestrone receptor (PR), Ki-67 receptor status, histological grade, tumor size, and axillary lymph nodes, there was a significant statistical difference between the two groups with and without complete pathological response (P<0.05).
Conclusion: The rate of complete pathological response to NAC in patients with locally advanced breast cancer was 18%.

The IOC is a crucial anatomical landmark for successful anesthesia in dentistry and oral and maxillofacial surgery. This study aimed to evaluate the position and dimensions of the IOC based on cone-beam computed tomography (CBCT).
Methods: This descriptive-analytical study was conducted on CBCT images of 250 individuals (105 males and 145 females) (mean age = 36.14±17.7 years) referring to a specialized oral and maxillofacial radiology clinic in Babol, Iran, during 2021-22. Three different types of IOC pathways from the sinus roof were measured: Completely located within the maxillary sinus roof (Type 1), located below the maxillary sinus roof (Type 2), and suspended from the maxillary sinus roof within the septum or lamella of the infraorbital ethmoid cell (Type 3). Additionally, the angles between the IOC and the infraorbital groove with the maxillary sinus roof, the angles between the IOC and the infraorbital groove, the lengths of the IOC and the infraorbital groove, and the distances of the IOC from various anatomical landmarks were measured. Distances of the IOC (mm) were evaluated from other anatomical landmarks according to gender and age groups.
Results: Overall, various pathways of the IOC from the sinus roof were 39.4% in Type 1, 53% in Type 2, and 7.6% in Type 3; the mean distance of the IOC to the infraorbital rim was 8.58±1.30 mm, and to the midpoint of the canine root was 10.16±0.81 mm. The mean length of the canal was 25.89±2.47 mm, and the infraorbital groove was 5.06±0.58 mm; and the mean angle between the IOC and the infraorbital groove was 153.20±3.28 degrees. In general, the distance of the IOC to the midpoint of the canine root on both the left and right sides was greater in males than in females, which was statistically significant on the left side (P<0.05). It was found that the length of the IOC and the angle between the IOC and the infraorbital groove on the left side had statistically significant correlations with age groups (P<0.05). The mean distance from the foramen to the infraorbital rim and the length of the IOC were proportional to the degree of nerve protrusion into the maxillary sinus; however, no significant correlation was found between the types of canals (degree of nerve protrusion) and gender.
Conclusion: Type 2 was the most common pathway of the IOC from the sinus roof. Although Type 3 was less common, due to the high risk associated with this type of canal, surgeons should be fully aware of the morphology and anatomical position of the IOC during sinus and orbital surgeries to reduce probable injuries.

ACL-injured patients exhibit weaker longitudinal arches and increased foot pronation compared to healthy individuals. This study aimed to determine the effect of short-term use of anti-pronation insoles on plantar pressure variables following ACL reconstruction (ACLR) with a pronated foot during gait.
Methods: This quasi-experimental study was conducted on 15 male participants who had undergone ACLR with a pronated foot (mean age= 23.2±4.5 years) and 15 healthy males (mean age= 22.7±4.3 years) in Ardabil, Iran during 2022. Plantar pressure values during gait with and without the use of anti-pronation insoles were recorded and compared using a foot scanner (sampling rate: 300 Hz).
Results: The effect of the group factor on the big toe plantar pressure variable was statistically significant (P<0.05). Pairwise comparison results demonstrated a significant increase in pressure in the ACLR group (154.63±41.71 N/cm²) compared to the healthy group (126.54±26.57 N/cm²) (P<0.05). Intragroup comparison results revealed a significant decrease in pressure on the second to fifth toes (215.73±60.74 N/cm²) and the first plantar (420.58±107.56 N/cm²) when using anti-pronation insoles compared to the non-insole condition (the second to fifth toes (201.57±76.21 N/cm²) and the first plantar (400.78±118.20 N/cm²) in the ACL reconstruction group (P<0.05).
Conclusion: The use of anti-pronation insoles can effectively reduce plantar pressure after ACLR in individuals with a pronated foot during gait.

This study aimed to determine the effects of four weeks of aerobic exercise and berberine supplementation on the expression of dopamine 5 receptor and poly (adenosin diphosphat [ADP]-ribose polymerase (PARP) genes in the heart tissue of methamphetamine-exposed rats.
Methods: In this experimental study, 30 female Wistar rats were randomly allocated into five groups of six: Control, methamphetamine, methamphetamine + aerobic exercise, methamphetamine + berberine, and methamphetamine + aerobic exercise + berberine. Intraperitoneal injections of methamphetamine (10 mg/kg) and aerobic exercise and berberine consumption (100 mg/kg) were administered for 4 weeks during the withdrawal period. The expression levels of dopamine 5 receptor and PARP genes was measured using real-time polymerase chain reaction (PCR).
Results: There was no significant difference in PARP gene expression between the methamphetamine group (1.02±0.65) and the control group (1.02±0.24). Similarly, there was no significant difference in dopamine 5 receptor gene expression between the methamphetamine group (5.74±4.94) and the control group (4.76±2.63). The expression levels of PARP and dopamine 5 receptor genes following exercise (1.01±0.55 and 4.30±1.96, respectively), berberine supplementation (0.61±0.25 and 2.97±1.45, respectively), and the combined intervention (0.67±0.30 and 3.43±1.87, respectively) showed no significant differences between the groups.
Conclusion: Short-term methamphetamine induction did not induce significant changes in the expression of dopamine 5 receptor and PARP genes in the hearts of methamphetamine-exposed rats.

This study aimed to determine the effect of eight weeks of corrective exercises on musculoskeletal pain levels in 13-15-year-old students.
Methods: This clinical trial was conducted on 101 students (44 girls and 57 boys) aged 13 to 15 experiencing musculoskeletal pain in various body parts in Bandar Mahshahr, Khuzestan Province, during the second half of the academic year 2021-2022. Participants were selected based on the Adolescent Nordic Musculoskeletal Questionnaire (NMQ), considering only the first question regarding the presence or absence of pain in each of the nine body regions (neck, shoulder, elbow, hand, upper back, lower back, pelvis, knee, and ankle) in the past seven days. A score of 1 was assigned to the presence of pain and 0 to the absence of pain. Participants were randomly assigned to two groups of 60: A control group and an intervention group. The intervention group performed corrective exercises at home for eight weeks, with three sessions per week, each lasting 40 minutes. No intervention was provided to the control group. Musculoskeletal pain levels in the neck, shoulder, upper back, elbow-arm, wrist, lower back, knee, and ankle were then compared in the pre-test, post-test, and follow-up.
Results: The mean and standard deviation of the total pain scores for the intervention and control groups were 1.32±0.41 and 1.33±0.46 in the pre-test, 1.01±0.08 and 1.34±0.46 at the post-test, and 1.17±0.36 and 1.11±0.31 at follow-up, respectively. Results revealed that eight weeks of corrective exercises significantly reduced musculoskeletal pain levels in the students’ neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, pelvis, and thigh (P<0.05); however, this improvement was not sustained at the follow-up.
Conclusion: Performing corrective exercises reduced musculoskeletal pain levels in the neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, and pelvis and thigh of 13-15-year-old students; however, the benefits were not sustained when the exercises were stopped.

This study aimed to compare the effects of two educational methods, with and without short message service (SMS) reminder, on adherence to treatment regimens among patients with acute coronary syndrome (ACS).
Methods: This clinical trial was conducted on 111 patients with ACS divided into three 37-people groups: A control group (receiving routine education), the first intervention group (receiving education and a booklet), and the second intervention group (receiving education, a booklet, and SMS reminders). The study was conducted in patients at the coronary care units (CCUs) and post-CCUs of the following educational therapeutic centers: Shahid Sayyad Shirazi in Gorgan, the Fifth Azar in Gorgan, Amir Al-Momenin in Kordkuy, and Al-E-Jalil in Aqqala, Iran, during 2019. The research instrument consisted of the Treatment Adherence Perception Questionnaire (TAPQ) in three domains, including dietary regimen, medication regimen, and exercise and activity, which was completed at the time of discharge and two months later.
Results: The mean scores of adherence to treatment dietary in patients with ACS two months after discharge in the three domains of dietary regimen, medication regimen, and exercise and activity were significantly higher in the group receiving education and SMS reminders (105.54±75.8, 16.00±2.71, and 23.67±3.85, respectively) compared to the education group (84.73±5.02, 11.05±1.69, and 17.45±2.48, respectively) (P<0.05). Moreover, the scores in the three investigated domains were significantly higher in both intervention groups compared to the control group (82.68±13.54, 11.40±1.96, and 17.67±5.04, respectively) (P<0.05).
Conclusion: The use of education and a booklet along with SMS reminders to patients with ACS discharged from the hospital increased adherence to treatment. This adherence was higher in the intervention group receiving SMS reminders.

Repetitive Transcranial Magnetic Stimulation (rTMS), among the efforts intended to modulate cortical excitability in the treatment of psychiatric disorders, has been believed to be associated with a specific disease. This study aimed to determine the effect of rTMS on the treatment of treatment-resistant amblyopia in adult patients.
Methods: This clinical trial was conducted on 16 patients (12 males and 4 females) with unilateral amblyopia, with a mean age of 30±5 years referring to the clinics of Khatam al-Anbia Eye Hospital, Mashhad, Iran, during 2016-17. Patients were randomly selected from those with unilateral amblyopia (refractive, strabismic, or mixed) who had not responded to conventional treatments (patching or penalization). The healthy eye was considered a control. The therapeutic intervention consisted of four rTMS sessions at two-week intervals. Visual acuity and contrast sensitivity were measured and compared three times: Before the intervention, at the first session of intervention, and at the fourth session of intervention.
Results: The mean visual acuity at baseline (0.36±0.19) was not significantly different compared to the first treatment session (0.41±0.1); however, a significant increase was observed compared to the fourth session (0.45±0.23) (P<0.05). The mean contrast sensitivity at baseline (2.02±0.74) was not significantly different compared to the first (1.97±0.63) and the fourth (2.16±0.94) treatment sessions.
Conclusion: In most follow-ups, improvement in contrast was not observed in patients with treatment-resistant amblyopia at older ages using rTMS. Only an improvement in visual acuity was observed in the last follow-up compared to the baseline in the patient group.

This case report describes a 44-year-old male who was incidentally found to have a renal mass during an abdominal and pelvic ultrasound. The patient's abdominal ultrasound revealed a mass, which was further evaluated with a CT scan. The CT findings suggested renal cell carcinoma. Suspecting malignancy, the patient underwent radical nephrectomy. Histopathological and immunohistochemical examinations ultimately diagnosed the mass as a cavernous hemangioma. Despite its benign nature, the patient was followed up with a control ultrasound three months post-surgery. This case is presented due to the significant clinical and radiological resemblance of this tumor to renal carcinomas, highlighting the importance of considering benign tumors in differential diagnoses.

Given the similarities between these conditions, the medications used by patients with rheumatoid arthritis (RA) may affect their periodontal indices. This study aimed to evaluate the periodontal index status in patients with RA undergoing immunosuppressive therapy.
Methods: This comparative cross-sectional study was conducted on 68 patients with RA in three treatment groups (20 on monotherapy, 24 on dual therapy, and 24 on triple treatment) and 20 healthy individuals with a plaque index (PI) below 35% in Ardabil, Iran during the second half of 2021. The monotherapy group included methotrexate or hydroxychloroquine; the dual therapy group included combinations of methotrexate with hydroxychloroquine, adalimumab, or infliximab; and the triple therapy group included combinations of methotrexate and hydroxychloroquine with adalimumab, etanercept, sulfasalazine, or leflunomide. Periodontal indices, including Plaque Index (PI), Clinical Attachment Loss (CAL), Gingival Index (GI), and Bleeding on Probing (BOP), were assessed.
Results: There were no statistically significant differences in periodontal indices among the three treatment groups (monotherapy, dual therapy, and triple therapy). The mean BOP index in the control group was significantly higher compared to the three medication groups (P<0.05). There were no statistically significant differences in the mean CAL and GI indices between the control group and the medication groups. The median PI in the control group was 29.6, and in the dual therapy group, it was 42.3, which was statistically significant (P<0.05).
Conclusion: The use of immunosuppressive drugs did not have a significant effect on the periodontal indices of patients with rheumatoid arthritis.

This study aimed to determine the antifungal activity of petroleum ether, dichloromethane, ethyl acetate, ethanol, and hydroethanol extracts from the aerial parts of Artemisia khorassanica, Artemisia scoparia, and Artemisia vulgaris against common dermatophytic fungi, including Trichophyton rubrum, Trichophyton verrucosum, Epidermophyton floccosum, and Microsporum canis.
Methods: This descriptive study examined the antifungal activity of various extracts from the aerial parts of Artemisia khorassanica, Artemisia scoparia, and Artemisia vulgaris against fungal isolates of Trichophyton rubrum, Trichophyton verrucosum, Microsporum canis, and Epidermophyton floccosum. The aerial parts of the three Artemisia species were extracted using five solvents: petroleum ether, dichloromethane, ethyl acetate, ethanol, and 50% hydroethanol. The extracts were screened for antidermatophytic effects against the fungi mentioned above, and the minimum inhibitory concentration (MIC) was determined using the agar dilution method. The most active extracts underwent preliminary phytochemical testing.
Results: In the initial screening, Microsporum canis and Trichophyton verrucosum showed the highest sensitivity (86.66%) and resistance (100%) to the tested extracts, respectively. Extracts from Artemisia scoparia exhibited the broadest range of activity. The most effective extracts, with an MIC of 78.12 µg/ml, were also from this plant. Hydroethanol extracts from all plant species demonstrated the least antidermatophytic activity. Preliminary phytochemical studies revealed the presence of terpenoids in all petroleum ether and dichloromethane extracts of the plant species.
Conclusion: Some lipophilic compounds, particularly in the petroleum ether and dichloromethane extracts of Artemisia scoparia, exhibit significant in vitro antidermatophytic activity.

Understanding the factors involved in the treatment of opium use is essential. This study aimed to evaluate inhibitory response and impulsivity in opium users.
Methods: This descriptive-analytical study was conducted on 170 opium users (139 men and 31 women) who visited the Methadone Maintenance Treatment Center in Gorgan, Iran during 2022, selected through convenience sampling. The Stop Signal Task (SST) was used to assess participants' inhibitory response, and the Barratt Impulsiveness Scale (BIS) was used to measure impulsivity levels.
Results: The average overall impulsivity score was 67.8±11.85. The average correct responses were 45.09±5.67, incorrect responses were 4.51±3.95, and delays were 0.96±2.32. The mean response time to each stimulus was 1290±512.83 milliseconds. There was a statistically significant correlation between impulsivity dimensions and age, correct responses and education level, and response time for inhibitory control with age and education level (P<0.05). There was no statistically significant correlation between the various dimensions of inhibitory response and impulsivity (cognitive impulsivity, non-planning impulsivity, and motor impulsivity) and overall impulsivity.
Conclusion: Opium users are generally impulsive. Additionally, younger individuals and those with lower education levels are more impulsive compared to others.

This study aimed to identify factors associated with weight regain after bariatric surgeries in obese patients in Gorgan, Iran.
Methods: This longitudinal study included 143 obese individuals (125 women and 18 men) with a mean age of 43.13±9.83 years who underwent bariatric surgery in Gorgan, Iran during 2013-19. Participants were invited to join the study via phone calls. Research variables (type of surgery, blood group, pre-surgery weight, and body mass index [BMI]) were extracted from patient records, and their current weight and waist circumference were measured and recorded. Weight regain was determined based on one of three different criteria: (1) regaining more than 25% of the maximum weight lost post-surgery, (2) regaining more than 10 kg from the minimum weight post-surgery, or (3) an increase of more than 5 BMI units from the lowest BMI post-surgery.
Results: Overall, 33% of individuals experienced weight regain, with 26.6% according to the first definition, 29.4% according to the second definition, and 18.2% according to the third definition. Men had a higher rate of weight regain (P<0.05). Additionally, 93.6% (44 cases) of those with weight regain had abdominal obesity. On average, 79.7% of participants who were 48 months post-bariatric surgery experienced some degree of weight regain. Individuals with a pre-surgery BMI of 50 or higher had a 2.69 times greater chance of weight regain compared to those with BMI lower 50 (P<0.05). The mean weight loss after surgery was significantly higher in individuals who experienced weight regain than those who did not (P<0.05). There was no significant statistical association between weight regain and the type of surgery, age, education level, marital status, or blood group.
Conclusion: Weight regain over time is a reality after bariatric surgery, indicating that this method is not a definitive cure for obesity. Therefore, long-term follow-up for weight control is crucial, especially for individuals with a pre-surgery BMI of 50 or higher or those who experienced significant weight loss post-surgery.

They also significantly influence individuals' physical, social, and psychological activities. This study aimed to determine the relationship between the Dental Caries Index (DMFT) and oral health-related quality of life.
Methods: This descriptive-analytical study was conducted on 61 patients (29 men and 32 women) aged 20-50 years who visited the Gorgan Dental School Clinic, Iran during 2019. The DMFT index, encompassing Decay (D), Missing (M), and Filled (F) teeth, was calculated. Quality of life was assessed using the 36-item DIDL (Dental Impact on Daily Living) questionnaire, which covers five domains: dental appearance and aesthetics, oral comfort, overall oral and dental function, eating limitations, and dental and jaw pain. Scores were categorized into three groups: dissatisfied (below 0), moderately satisfied (0 to 7), and satisfied (above 7).
Results: The mean score for oral health-related quality of life was 5.14±0.229, indicating a relative level of satisfaction. Pearson's correlation coefficient between DMFT and oral health-related quality of life was -0.358, suggesting a significant inverse relationship between DMFT and quality of life (P<0.05). The mean DMFT score ranged from 0 to 28, with a mean of 9.36, and the most frequent scores were 7, 11, and 13, each accounting for 11.5% of the sample. The mean decay (D) score was 3.44, the mean missing (M) score was 1.98, and the mean filled (F) score was 3.93, with ranges of 0-12, 0-19, and 0-13, respectively.
Conclusion: The results of this study indicate an inverse impact of the Dental Caries Index on patients' quality of life. Oral health-related quality of life is a multifaceted construct that affects various aspects such as appearance, oral comfort, and eating limitations, which are critical components of overall quality of life and satisfaction.

As such, it poses a life-threatening consequence for chronic patients, although it is rarely assessed and treated in clinical settings. One of the diseases associated with high levels of physical and mental pain is the rare disorder neurofibromatosis. This study aimed to evaluate mental pain in patients with neurofibromatosis and its association with disease severity.
Methods: This descriptive-analytical study was conducted on 207 patients with neurofibromatosis who were members of the Iranian Neurofibromatosis Support Association during 2023. Data collection tools included a demographic and clinical information registration form and the Orbach and Mikulincer Mental Pain Scale (OMMP), which comprises 44 items and 6 subscales, with a scoring range from 44 to 220.
Results: The total mental pain score was 121.15±42.41, with a range of 44 to 206. The total mental pain scores for men and women were 123.67±38.98 and 120.31±43.58, respectively. The "confusion" subscale had the highest average score, while the "fear of loneliness" subscale had the lowest average score. There was a statistically significant association between the total mental pain score and its subscales with the severity of the disease and the patient's educational level (P<0.05).
Conclusion: The mental pain scores of patients with neurofibromatosis were evaluated to be relatively unfavorable.

One crucial aspect of this is maintaining the performance of hemodialysis catheters. Our study, which aimed to evaluate the one-year performance of long-term catheters in chronic hemodialysis patients in Golestan Province, is a critical step toward improving patient care in this population.
Methods: This descriptive-analytical study was conducted on 99 patients (34 men and 65 women) with ESRD who were candidates for starting or continuing dialysis with a catheter in the educational and therapeutic centers of Golestan Province, Iran during 2021-22. Transjugular catheters were placed for the patients, and after one year, variables such as age, gender, history of diabetes, history of hypertension, catheter placement site (right or left jugular), and antiplatelet medication use were evaluated concerning the performance of long-term catheters in providing adequate flow for hemodialysis.
Results: In 91 patients (91.9%), the one-year catheter performance was assessed as satisfactory. The age of 61.6% of the patients were over 60 years old. Sixty-nine patients (69.7%) had a history of hypertension, and 58 patients (58.6%) had a history of diabetes. Fifty-seven patients (57.6%) received antiplatelet medication. The catheters were placed on the right side in 82 patients (82.8%). Catheter performance in patients taking antiplatelet medication was non-significantly higher than in those not taking antiplatelet medicines.
Conclusion: The performance of long-term catheters in chronic hemodialysis patients with ESRD showed no significant correlation with age, gender, diabetes, hypertension, antiplatelet medication use, or the side of the jugular vein where the catheter was placed.

The transcriptional mechanisms responsible for regulating the gene expression of myosin heavy chain types are not well understood. This study aimed to determine the effect of a single session of intense resistance exercise with glutamine supplementation on the relative expression of the alpha and IIX isoforms of the myosin heavy chain gene in male rats.
Methods: This experimental study was conducted on 30 adult male Wistar rats divided into three groups: control, intense resistance exercise (first experimental group), and fierce resistance exercise combined with glutamine supplementation (second experimental group). The exercise groups participated in a single session of resistance climbing on an inclined plane with 4 sets of 5 repetitions, 30 seconds of rest between repetitions, and 2 minutes of rest between sets. Glutamine supplement powder was dissolved in 100 ml of distilled water at a dose of 0.5 grams per kilogram of body weight and administered daily via gavage for 5 days. The expression of alpha and IIX isoforms of the myosin heavy chain gene was examined in the extensor digitorum longus muscle tissue.
Results: The relative expression of the alpha myosin heavy chain gene in the fast-twitch muscle fibers increased significantly in the first experimental group (1.93±0.298) and the second experimental group (1.65±0.195) compared to the control group (P<0.05). The relative expression of the IIX motor unit gene in the fast-twitch muscle fibers also increased significantly in the first experimental group (1.42±0.239) and the second experimental group (1.26±0.190) compared to the control group (P<0.05). The increase in the relative expression of the alpha myosin heavy chain gene in the first experimental group compared to the second experimental group was statistically significant (P<0.05). However, the increase in the relative expression of the IIX motor unit gene in the first experimental group compared to the second experimental group was not statistically significant.
Conclusion: Our study concludes that a single session of intense resistance exercise, with or without glutamine supplementation, significantly increases the relative expression of the alpha myosin heavy chain gene and the IIX motor unit gene in the fast-twitch muscle fibers of the extensor digitorum longus muscle in adult male rats. These findings provide valuable insights into the molecular

To ensure a comprehensive review, a search for original research, review articles, and clinical trials in both Persian and English was conducted using databases such as WOS, SID, ISC, Magiran, Scopus, PubMed, and Google Scholar. The search covered publications during January 2008 to March 2023. A total of 76 relevant articles were selected based on strict inclusion and exclusion criteria, with 22 articles ultimately reviewed and analyzed regarding the effects of various corrective exercises and supportive tools on genu valgum. Findings from one study indicated that aerobic exercises had a significant impact on reducing body mass index (BMI) and the severity of genuvalgum. Other studies reported positive effects of resistance and corrective exercises on improving muscle electrical activity and knee stability. One study demonstrated that the use of orthotic insoles could significantly enhance knee joint support during stair descent. Six studies highlighted the positive effects of using orthoses, wedges, and braces in individuals with genu valgum. Conversely, one study pointed out the negative impact of these tools, citing the reduced limiting angle of the brace, increased applied forces, and, ultimately, greater injury risk. However, findings from three studies overwhelmingly supported the positive effects of using kinesiotape in individuals with genu valgum, providing optimism about the effectiveness of these interventions. In conclusion, our review underscores the promising potential of corrective exercises, particularly resistance exercises with TheraBand, and the combination of these with supportive tools such as insoles for arch support and kinesiotape. These interventions show significant promise in reducing the degree of knee valgus in individuals with genu valgum. This hopeful outlook can inspire healthcare professionals and individuals seeking evidence-based interventions for genu valgum, empowering them with the knowledge to make informed decisions about their care.

Methods: This retrospective descriptive study was conducted on 9 patients (4 women and 5 men) with liver cirrhosis infected with COVID-19 hospitalized at Shahid Sayyad Shirazi Educational and Therapeutic Center in Gorgan, Iran during 2019-20. COVID-19 infection was diagnosed by a positive polymerase chain reaction (PCR) test. The Child-Pugh score was used to classify the severity of liver disease. Demographic and clinical data, including initial symptoms and complaints, laboratory results, need for intensive care unit (ICU) admission, length of hospital stay, and treatment outcomes, were extracted from patients’ medical records.
Results: The severity of liver disease was classified as Class B in 7 patients. Comorbidities included cardiovascular diseases and hypertension in 2 patients each, as well as diabetes and asthma in one patient each. Clinical manifestations at the time of COVID-19 diagnosis included ascites in 6 patients; fever in 5 patients; respiratory distress and anorexia in 4 patients each; cough, oxygen saturation less than 93%, and muscle pain in 3 patients each; nausea and vomiting in 2 patients; and abdominal pain and decreased level of consciousness in one patient each. Albumin levels were less than 4 g/dL in all patients. Hemoglobin was less than 12 g/dL in 7 patients. Thrombocytopenia was observed in 8 patients, leukocytosis in one patient, and leukopenia and pancytopenia in 4 patients each. Alanine transaminase (ALT) and aspartate transaminase (AST) levels were higher than 40 U/L in 6 and 5 patients, respectively. Only one patient died, a 60-year-old woman with a history of fatty liver disease, cardiovascular disease, and uncontrolled Class C cirrhosis.
Conclusion: The most common clinical manifestations in patients with liver cirrhosis infected with COVID-19 consisted of ascites, fever, respiratory distress, and anorexia, and the most common laboratory manifestations were hypoalbuminemia and thrombocytopenia.

Methods: This descriptive-analytical study was conducted on two sheep and two cow livers infected with hydatid cysts, and the human colorectal adenocarcinoma cell line (LS174T) purchased from the Pasteur Institute of Iran at the Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Iran during 2022. Cyst fluid, protoscolices, and the hyaline layer were isolated from the hydatid cyst-infected livers, and glycoproteins and glycolipids from different parts of the cyst were extracted using the chloroform-methanol method. Carbohydrates were purified using the beta-elimination method and their presence was confirmed using the phenol-sulfuric acid method. The cytotoxicity of purified carbohydrates on the LS174T cell line was evaluated using the methyl tetrazolium (MTT) assay for 24 hours.
Results: Concentrations of 0.5 and 0.25 of purified carbohydrates from glycoproteins and glycolipids of hydatid cysts significantly inhibited the growth of LS174T cells (P<0.05). Initial cytotoxicity evaluation showed that purified carbohydrates from glycoproteins of sheep cyst fluid (38.60±1.33%), glycoproteins of cow cyst hyaline layer (36.61±1.76%), glycolipids of cow cyst hyaline layer (38.94±2.99%), glycoproteins of cow cyst protoscolices (40.27±3.66%), and glycolipids of sheep cyst protoscolices (37.94±1.99%) had significantly more pronounced inhibitory effects (P<0.05). Subsequent screening with the MTT assay revealed that purified carbohydrates from glycoproteins isolated from sheep hydatid cyst fluid (52.35±10.24%), glycolipids isolated from cow hydatid cyst hyaline layer (53.40±7.88%), and glycolipids isolated from sheep hydatid cyst protoscolices (53.05±5.06%) had significantly more pronounced inhibitory effects on the growth of LS174T cancer cells (P<0.05).
Conclusion: Carbohydrates isolated from glycoproteins and glycolipids of the hyaline layer, fluid, and protoscolices of hydatid cysts have significant anticancer effects on the LS174T colorectal cancer cell line.

Methods: This descriptive-analytical study was conducted on 100 patients with breast cancer (mean age= 41.14±10.06 years) referring to the surgical clinic of the Fifth Azar Educational and Therapeutic Center in Gorgan, Iran during 2013-18. Patients without distant metastasis underwent NAC treatment regimen followed by surgery. Demographic characteristics, types of drugs, and molecular receptor characteristics, and their response to treatment were recorded in a checklist. Treatment response and overall patient survival were evaluated.
Results: The mean tumor size before NAC was 3.01±2.47 cm (range= 0-8, median= 2) and 16% were determined to be grade one, 52% were determined to be grade 2, and 32% were determined to be grade 3. Thirty-six percent of patients had a positive family history. Forty-six percent were estrogen receptor (ER) positive, 40% were PR positive, 22% were human epidermal growth factor receptor 2 (Her-2) positive, and 78% were Her-2 negative. Thirty-six percent had a Ki-67 index greater than 30%. Eighteen percent of patients had a complete pathological response, and 82% had a partial or negative response. In terms of family history of breast cancer, Her2, ER, progestrone receptor (PR), Ki-67 receptor status, histological grade, tumor size, and axillary lymph nodes, there was a significant statistical difference between the two groups with and without complete pathological response (P<0.05).
Conclusion: The rate of complete pathological response to NAC in patients with locally advanced breast cancer was 18%.

Methods: This descriptive-analytical study was conducted on CBCT images of 250 individuals (105 males and 145 females) (mean age = 36.14±17.7 years) referring to a specialized oral and maxillofacial radiology clinic in Babol, Iran, during 2021-22. Three different types of IOC pathways from the sinus roof were measured: Completely located within the maxillary sinus roof (Type 1), located below the maxillary sinus roof (Type 2), and suspended from the maxillary sinus roof within the septum or lamella of the infraorbital ethmoid cell (Type 3). Additionally, the angles between the IOC and the infraorbital groove with the maxillary sinus roof, the angles between the IOC and the infraorbital groove, the lengths of the IOC and the infraorbital groove, and the distances of the IOC from various anatomical landmarks were measured. Distances of the IOC (mm) were evaluated from other anatomical landmarks according to gender and age groups.
Results: Overall, various pathways of the IOC from the sinus roof were 39.4% in Type 1, 53% in Type 2, and 7.6% in Type 3; the mean distance of the IOC to the infraorbital rim was 8.58±1.30 mm, and to the midpoint of the canine root was 10.16±0.81 mm. The mean length of the canal was 25.89±2.47 mm, and the infraorbital groove was 5.06±0.58 mm; and the mean angle between the IOC and the infraorbital groove was 153.20±3.28 degrees. In general, the distance of the IOC to the midpoint of the canine root on both the left and right sides was greater in males than in females, which was statistically significant on the left side (P<0.05). It was found that the length of the IOC and the angle between the IOC and the infraorbital groove on the left side had statistically significant correlations with age groups (P<0.05). The mean distance from the foramen to the infraorbital rim and the length of the IOC were proportional to the degree of nerve protrusion into the maxillary sinus; however, no significant correlation was found between the types of canals (degree of nerve protrusion) and gender.
Conclusion: Type 2 was the most common pathway of the IOC from the sinus roof. Although Type 3 was less common, due to the high risk associated with this type of canal, surgeons should be fully aware of the morphology and anatomical position of the IOC during sinus and orbital surgeries to reduce probable injuries.

Methods: This quasi-experimental study was conducted on 15 male participants who had undergone ACLR with a pronated foot (mean age= 23.2±4.5 years) and 15 healthy males (mean age= 22.7±4.3 years) in Ardabil, Iran during 2022. Plantar pressure values during gait with and without the use of anti-pronation insoles were recorded and compared using a foot scanner (sampling rate: 300 Hz).
Results: The effect of the group factor on the big toe plantar pressure variable was statistically significant (P<0.05). Pairwise comparison results demonstrated a significant increase in pressure in the ACLR group (154.63±41.71 N/cm²) compared to the healthy group (126.54±26.57 N/cm²) (P<0.05). Intragroup comparison results revealed a significant decrease in pressure on the second to fifth toes (215.73±60.74 N/cm²) and the first plantar (420.58±107.56 N/cm²) when using anti-pronation insoles compared to the non-insole condition (the second to fifth toes (201.57±76.21 N/cm²) and the first plantar (400.78±118.20 N/cm²) in the ACL reconstruction group (P<0.05).
Conclusion: The use of anti-pronation insoles can effectively reduce plantar pressure after ACLR in individuals with a pronated foot during gait.

Methods: In this experimental study, 30 female Wistar rats were randomly allocated into five groups of six: Control, methamphetamine, methamphetamine + aerobic exercise, methamphetamine + berberine, and methamphetamine + aerobic exercise + berberine. Intraperitoneal injections of methamphetamine (10 mg/kg) and aerobic exercise and berberine consumption (100 mg/kg) were administered for 4 weeks during the withdrawal period. The expression levels of dopamine 5 receptor and PARP genes was measured using real-time polymerase chain reaction (PCR).
Results: There was no significant difference in PARP gene expression between the methamphetamine group (1.02±0.65) and the control group (1.02±0.24). Similarly, there was no significant difference in dopamine 5 receptor gene expression between the methamphetamine group (5.74±4.94) and the control group (4.76±2.63). The expression levels of PARP and dopamine 5 receptor genes following exercise (1.01±0.55 and 4.30±1.96, respectively), berberine supplementation (0.61±0.25 and 2.97±1.45, respectively), and the combined intervention (0.67±0.30 and 3.43±1.87, respectively) showed no significant differences between the groups.
Conclusion: Short-term methamphetamine induction did not induce significant changes in the expression of dopamine 5 receptor and PARP genes in the hearts of methamphetamine-exposed rats.

Methods: This clinical trial was conducted on 101 students (44 girls and 57 boys) aged 13 to 15 experiencing musculoskeletal pain in various body parts in Bandar Mahshahr, Khuzestan Province, during the second half of the academic year 2021-2022. Participants were selected based on the Adolescent Nordic Musculoskeletal Questionnaire (NMQ), considering only the first question regarding the presence or absence of pain in each of the nine body regions (neck, shoulder, elbow, hand, upper back, lower back, pelvis, knee, and ankle) in the past seven days. A score of 1 was assigned to the presence of pain and 0 to the absence of pain. Participants were randomly assigned to two groups of 60: A control group and an intervention group. The intervention group performed corrective exercises at home for eight weeks, with three sessions per week, each lasting 40 minutes. No intervention was provided to the control group. Musculoskeletal pain levels in the neck, shoulder, upper back, elbow-arm, wrist, lower back, knee, and ankle were then compared in the pre-test, post-test, and follow-up.
Results: The mean and standard deviation of the total pain scores for the intervention and control groups were 1.32±0.41 and 1.33±0.46 in the pre-test, 1.01±0.08 and 1.34±0.46 at the post-test, and 1.17±0.36 and 1.11±0.31 at follow-up, respectively. Results revealed that eight weeks of corrective exercises significantly reduced musculoskeletal pain levels in the students’ neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, pelvis, and thigh (P<0.05); however, this improvement was not sustained at the follow-up.
Conclusion: Performing corrective exercises reduced musculoskeletal pain levels in the neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, and pelvis and thigh of 13-15-year-old students; however, the benefits were not sustained when the exercises were stopped.

Methods: This clinical trial was conducted on 111 patients with ACS divided into three 37-people groups: A control group (receiving routine education), the first intervention group (receiving education and a booklet), and the second intervention group (receiving education, a booklet, and SMS reminders). The study was conducted in patients at the coronary care units (CCUs) and post-CCUs of the following educational therapeutic centers: Shahid Sayyad Shirazi in Gorgan, the Fifth Azar in Gorgan, Amir Al-Momenin in Kordkuy, and Al-E-Jalil in Aqqala, Iran, during 2019. The research instrument consisted of the Treatment Adherence Perception Questionnaire (TAPQ) in three domains, including dietary regimen, medication regimen, and exercise and activity, which was completed at the time of discharge and two months later.
Results: The mean scores of adherence to treatment dietary in patients with ACS two months after discharge in the three domains of dietary regimen, medication regimen, and exercise and activity were significantly higher in the group receiving education and SMS reminders (105.54±75.8, 16.00±2.71, and 23.67±3.85, respectively) compared to the education group (84.73±5.02, 11.05±1.69, and 17.45±2.48, respectively) (P<0.05). Moreover, the scores in the three investigated domains were significantly higher in both intervention groups compared to the control group (82.68±13.54, 11.40±1.96, and 17.67±5.04, respectively) (P<0.05).
Conclusion: The use of education and a booklet along with SMS reminders to patients with ACS discharged from the hospital increased adherence to treatment. This adherence was higher in the intervention group receiving SMS reminders.

Methods: This clinical trial was conducted on 16 patients (12 males and 4 females) with unilateral amblyopia, with a mean age of 30±5 years referring to the clinics of Khatam al-Anbia Eye Hospital, Mashhad, Iran, during 2016-17. Patients were randomly selected from those with unilateral amblyopia (refractive, strabismic, or mixed) who had not responded to conventional treatments (patching or penalization). The healthy eye was considered a control. The therapeutic intervention consisted of four rTMS sessions at two-week intervals. Visual acuity and contrast sensitivity were measured and compared three times: Before the intervention, at the first session of intervention, and at the fourth session of intervention.
Results: The mean visual acuity at baseline (0.36±0.19) was not significantly different compared to the first treatment session (0.41±0.1); however, a significant increase was observed compared to the fourth session (0.45±0.23) (P<0.05). The mean contrast sensitivity at baseline (2.02±0.74) was not significantly different compared to the first (1.97±0.63) and the fourth (2.16±0.94) treatment sessions.
Conclusion: In most follow-ups, improvement in contrast was not observed in patients with treatment-resistant amblyopia at older ages using rTMS. Only an improvement in visual acuity was observed in the last follow-up compared to the baseline in the patient group.

Methods: This comparative cross-sectional study was conducted on 68 patients with RA in three treatment groups (20 on monotherapy, 24 on dual therapy, and 24 on triple treatment) and 20 healthy individuals with a plaque index (PI) below 35% in Ardabil, Iran during the second half of 2021. The monotherapy group included methotrexate or hydroxychloroquine; the dual therapy group included combinations of methotrexate with hydroxychloroquine, adalimumab, or infliximab; and the triple therapy group included combinations of methotrexate and hydroxychloroquine with adalimumab, etanercept, sulfasalazine, or leflunomide. Periodontal indices, including Plaque Index (PI), Clinical Attachment Loss (CAL), Gingival Index (GI), and Bleeding on Probing (BOP), were assessed.
Results: There were no statistically significant differences in periodontal indices among the three treatment groups (monotherapy, dual therapy, and triple therapy). The mean BOP index in the control group was significantly higher compared to the three medication groups (P<0.05). There were no statistically significant differences in the mean CAL and GI indices between the control group and the medication groups. The median PI in the control group was 29.6, and in the dual therapy group, it was 42.3, which was statistically significant (P<0.05).
Conclusion: The use of immunosuppressive drugs did not have a significant effect on the periodontal indices of patients with rheumatoid arthritis.

Methods: This descriptive study examined the antifungal activity of various extracts from the aerial parts of Artemisia khorassanica, Artemisia scoparia, and Artemisia vulgaris against fungal isolates of Trichophyton rubrum, Trichophyton verrucosum, Microsporum canis, and Epidermophyton floccosum. The aerial parts of the three Artemisia species were extracted using five solvents: petroleum ether, dichloromethane, ethyl acetate, ethanol, and 50% hydroethanol. The extracts were screened for antidermatophytic effects against the fungi mentioned above, and the minimum inhibitory concentration (MIC) was determined using the agar dilution method. The most active extracts underwent preliminary phytochemical testing.
Results: In the initial screening, Microsporum canis and Trichophyton verrucosum showed the highest sensitivity (86.66%) and resistance (100%) to the tested extracts, respectively. Extracts from Artemisia scoparia exhibited the broadest range of activity. The most effective extracts, with an MIC of 78.12 µg/ml, were also from this plant. Hydroethanol extracts from all plant species demonstrated the least antidermatophytic activity. Preliminary phytochemical studies revealed the presence of terpenoids in all petroleum ether and dichloromethane extracts of the plant species.
Conclusion: Some lipophilic compounds, particularly in the petroleum ether and dichloromethane extracts of Artemisia scoparia, exhibit significant in vitro antidermatophytic activity.

Methods: This descriptive-analytical study was conducted on 170 opium users (139 men and 31 women) who visited the Methadone Maintenance Treatment Center in Gorgan, Iran during 2022, selected through convenience sampling. The Stop Signal Task (SST) was used to assess participants' inhibitory response, and the Barratt Impulsiveness Scale (BIS) was used to measure impulsivity levels.
Results: The average overall impulsivity score was 67.8±11.85. The average correct responses were 45.09±5.67, incorrect responses were 4.51±3.95, and delays were 0.96±2.32. The mean response time to each stimulus was 1290±512.83 milliseconds. There was a statistically significant correlation between impulsivity dimensions and age, correct responses and education level, and response time for inhibitory control with age and education level (P<0.05). There was no statistically significant correlation between the various dimensions of inhibitory response and impulsivity (cognitive impulsivity, non-planning impulsivity, and motor impulsivity) and overall impulsivity.
Conclusion: Opium users are generally impulsive. Additionally, younger individuals and those with lower education levels are more impulsive compared to others.

Methods: This longitudinal study included 143 obese individuals (125 women and 18 men) with a mean age of 43.13±9.83 years who underwent bariatric surgery in Gorgan, Iran during 2013-19. Participants were invited to join the study via phone calls. Research variables (type of surgery, blood group, pre-surgery weight, and body mass index [BMI]) were extracted from patient records, and their current weight and waist circumference were measured and recorded. Weight regain was determined based on one of three different criteria: (1) regaining more than 25% of the maximum weight lost post-surgery, (2) regaining more than 10 kg from the minimum weight post-surgery, or (3) an increase of more than 5 BMI units from the lowest BMI post-surgery.
Results: Overall, 33% of individuals experienced weight regain, with 26.6% according to the first definition, 29.4% according to the second definition, and 18.2% according to the third definition. Men had a higher rate of weight regain (P<0.05). Additionally, 93.6% (44 cases) of those with weight regain had abdominal obesity. On average, 79.7% of participants who were 48 months post-bariatric surgery experienced some degree of weight regain. Individuals with a pre-surgery BMI of 50 or higher had a 2.69 times greater chance of weight regain compared to those with BMI lower 50 (P<0.05). The mean weight loss after surgery was significantly higher in individuals who experienced weight regain than those who did not (P<0.05). There was no significant statistical association between weight regain and the type of surgery, age, education level, marital status, or blood group.
Conclusion: Weight regain over time is a reality after bariatric surgery, indicating that this method is not a definitive cure for obesity. Therefore, long-term follow-up for weight control is crucial, especially for individuals with a pre-surgery BMI of 50 or higher or those who experienced significant weight loss post-surgery.

Methods: This descriptive-analytical study was conducted on 61 patients (29 men and 32 women) aged 20-50 years who visited the Gorgan Dental School Clinic, Iran during 2019. The DMFT index, encompassing Decay (D), Missing (M), and Filled (F) teeth, was calculated. Quality of life was assessed using the 36-item DIDL (Dental Impact on Daily Living) questionnaire, which covers five domains: dental appearance and aesthetics, oral comfort, overall oral and dental function, eating limitations, and dental and jaw pain. Scores were categorized into three groups: dissatisfied (below 0), moderately satisfied (0 to 7), and satisfied (above 7).
Results: The mean score for oral health-related quality of life was 5.14±0.229, indicating a relative level of satisfaction. Pearson's correlation coefficient between DMFT and oral health-related quality of life was -0.358, suggesting a significant inverse relationship between DMFT and quality of life (P<0.05). The mean DMFT score ranged from 0 to 28, with a mean of 9.36, and the most frequent scores were 7, 11, and 13, each accounting for 11.5% of the sample. The mean decay (D) score was 3.44, the mean missing (M) score was 1.98, and the mean filled (F) score was 3.93, with ranges of 0-12, 0-19, and 0-13, respectively.
Conclusion: The results of this study indicate an inverse impact of the Dental Caries Index on patients' quality of life. Oral health-related quality of life is a multifaceted construct that affects various aspects such as appearance, oral comfort, and eating limitations, which are critical components of overall quality of life and satisfaction.

Methods: This descriptive-analytical study was conducted on 99 patients (34 men and 65 women) with ESRD who were candidates for starting or continuing dialysis with a catheter in the educational and therapeutic centers of Golestan Province, Iran during 2021-22. Transjugular catheters were placed for the patients, and after one year, variables such as age, gender, history of diabetes, history of hypertension, catheter placement site (right or left jugular), and antiplatelet medication use were evaluated concerning the performance of long-term catheters in providing adequate flow for hemodialysis.
Results: In 91 patients (91.9%), the one-year catheter performance was assessed as satisfactory. The age of 61.6% of the patients were over 60 years old. Sixty-nine patients (69.7%) had a history of hypertension, and 58 patients (58.6%) had a history of diabetes. Fifty-seven patients (57.6%) received antiplatelet medication. The catheters were placed on the right side in 82 patients (82.8%). Catheter performance in patients taking antiplatelet medication was non-significantly higher than in those not taking antiplatelet medicines.
Conclusion: The performance of long-term catheters in chronic hemodialysis patients with ESRD showed no significant correlation with age, gender, diabetes, hypertension, antiplatelet medication use, or the side of the jugular vein where the catheter was placed.

Methods: This experimental study was conducted on 30 adult male Wistar rats divided into three groups: control, intense resistance exercise (first experimental group), and fierce resistance exercise combined with glutamine supplementation (second experimental group). The exercise groups participated in a single session of resistance climbing on an inclined plane with 4 sets of 5 repetitions, 30 seconds of rest between repetitions, and 2 minutes of rest between sets. Glutamine supplement powder was dissolved in 100 ml of distilled water at a dose of 0.5 grams per kilogram of body weight and administered daily via gavage for 5 days. The expression of alpha and IIX isoforms of the myosin heavy chain gene was examined in the extensor digitorum longus muscle tissue.
Results: The relative expression of the alpha myosin heavy chain gene in the fast-twitch muscle fibers increased significantly in the first experimental group (1.93±0.298) and the second experimental group (1.65±0.195) compared to the control group (P<0.05). The relative expression of the IIX motor unit gene in the fast-twitch muscle fibers also increased significantly in the first experimental group (1.42±0.239) and the second experimental group (1.26±0.190) compared to the control group (P<0.05). The increase in the relative expression of the alpha myosin heavy chain gene in the first experimental group compared to the second experimental group was statistically significant (P<0.05). However, the increase in the relative expression of the IIX motor unit gene in the first experimental group compared to the second experimental group was not statistically significant.
Conclusion: Our study concludes that a single session of intense resistance exercise, with or without glutamine supplementation, significantly increases the relative expression of the alpha myosin heavy chain gene and the IIX motor unit gene in the fast-twitch muscle fibers of the extensor digitorum longus muscle in adult male rats. These findings provide valuable insights into the molecular

Methods: This retrospective descriptive study was conducted on 9 patients (4 women and 5 men) with liver cirrhosis infected with COVID-19 hospitalized at Shahid Sayyad Shirazi Educational and Therapeutic Center in Gorgan, Iran during 2019-20. COVID-19 infection was diagnosed by a positive polymerase chain reaction (PCR) test. The Child-Pugh score was used to classify the severity of liver disease. Demographic and clinical data, including initial symptoms and complaints, laboratory results, need for intensive care unit (ICU) admission, length of hospital stay, and treatment outcomes, were extracted from patients’ medical records.
Results: The severity of liver disease was classified as Class B in 7 patients. Comorbidities included cardiovascular diseases and hypertension in 2 patients each, as well as diabetes and asthma in one patient each. Clinical manifestations at the time of COVID-19 diagnosis included ascites in 6 patients; fever in 5 patients; respiratory distress and anorexia in 4 patients each; cough, oxygen saturation less than 93%, and muscle pain in 3 patients each; nausea and vomiting in 2 patients; and abdominal pain and decreased level of consciousness in one patient each. Albumin levels were less than 4 g/dL in all patients. Hemoglobin was less than 12 g/dL in 7 patients. Thrombocytopenia was observed in 8 patients, leukocytosis in one patient, and leukopenia and pancytopenia in 4 patients each. Alanine transaminase (ALT) and aspartate transaminase (AST) levels were higher than 40 U/L in 6 and 5 patients, respectively. Only one patient died, a 60-year-old woman with a history of fatty liver disease, cardiovascular disease, and uncontrolled Class C cirrhosis.
Conclusion: The most common clinical manifestations in patients with liver cirrhosis infected with COVID-19 consisted of ascites, fever, respiratory distress, and anorexia, and the most common laboratory manifestations were hypoalbuminemia and thrombocytopenia.

Methods: This descriptive-analytical study was conducted on two sheep and two cow livers infected with hydatid cysts, and the human colorectal adenocarcinoma cell line (LS174T) purchased from the Pasteur Institute of Iran at the Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Iran during 2022. Cyst fluid, protoscolices, and the hyaline layer were isolated from the hydatid cyst-infected livers, and glycoproteins and glycolipids from different parts of the cyst were extracted using the chloroform-methanol method. Carbohydrates were purified using the beta-elimination method and their presence was confirmed using the phenol-sulfuric acid method. The cytotoxicity of purified carbohydrates on the LS174T cell line was evaluated using the methyl tetrazolium (MTT) assay for 24 hours.
Results: Concentrations of 0.5 and 0.25 of purified carbohydrates from glycoproteins and glycolipids of hydatid cysts significantly inhibited the growth of LS174T cells (P<0.05). Initial cytotoxicity evaluation showed that purified carbohydrates from glycoproteins of sheep cyst fluid (38.60±1.33%), glycoproteins of cow cyst hyaline layer (36.61±1.76%), glycolipids of cow cyst hyaline layer (38.94±2.99%), glycoproteins of cow cyst protoscolices (40.27±3.66%), and glycolipids of sheep cyst protoscolices (37.94±1.99%) had significantly more pronounced inhibitory effects (P<0.05). Subsequent screening with the MTT assay revealed that purified carbohydrates from glycoproteins isolated from sheep hydatid cyst fluid (52.35±10.24%), glycolipids isolated from cow hydatid cyst hyaline layer (53.40±7.88%), and glycolipids isolated from sheep hydatid cyst protoscolices (53.05±5.06%) had significantly more pronounced inhibitory effects on the growth of LS174T cancer cells (P<0.05).
Conclusion: Carbohydrates isolated from glycoproteins and glycolipids of the hyaline layer, fluid, and protoscolices of hydatid cysts have significant anticancer effects on the LS174T colorectal cancer cell line.

Methods: This descriptive-analytical study was conducted on 100 patients with breast cancer (mean age= 41.14±10.06 years) referring to the surgical clinic of the Fifth Azar Educational and Therapeutic Center in Gorgan, Iran during 2013-18. Patients without distant metastasis underwent NAC treatment regimen followed by surgery. Demographic characteristics, types of drugs, and molecular receptor characteristics, and their response to treatment were recorded in a checklist. Treatment response and overall patient survival were evaluated.
Results: The mean tumor size before NAC was 3.01±2.47 cm (range= 0-8, median= 2) and 16% were determined to be grade one, 52% were determined to be grade 2, and 32% were determined to be grade 3. Thirty-six percent of patients had a positive family history. Forty-six percent were estrogen receptor (ER) positive, 40% were PR positive, 22% were human epidermal growth factor receptor 2 (Her-2) positive, and 78% were Her-2 negative. Thirty-six percent had a Ki-67 index greater than 30%. Eighteen percent of patients had a complete pathological response, and 82% had a partial or negative response. In terms of family history of breast cancer, Her2, ER, progestrone receptor (PR), Ki-67 receptor status, histological grade, tumor size, and axillary lymph nodes, there was a significant statistical difference between the two groups with and without complete pathological response (P<0.05).
Conclusion: The rate of complete pathological response to NAC in patients with locally advanced breast cancer was 18%.

Methods: This descriptive-analytical study was conducted on CBCT images of 250 individuals (105 males and 145 females) (mean age = 36.14±17.7 years) referring to a specialized oral and maxillofacial radiology clinic in Babol, Iran, during 2021-22. Three different types of IOC pathways from the sinus roof were measured: Completely located within the maxillary sinus roof (Type 1), located below the maxillary sinus roof (Type 2), and suspended from the maxillary sinus roof within the septum or lamella of the infraorbital ethmoid cell (Type 3). Additionally, the angles between the IOC and the infraorbital groove with the maxillary sinus roof, the angles between the IOC and the infraorbital groove, the lengths of the IOC and the infraorbital groove, and the distances of the IOC from various anatomical landmarks were measured. Distances of the IOC (mm) were evaluated from other anatomical landmarks according to gender and age groups.
Results: Overall, various pathways of the IOC from the sinus roof were 39.4% in Type 1, 53% in Type 2, and 7.6% in Type 3; the mean distance of the IOC to the infraorbital rim was 8.58±1.30 mm, and to the midpoint of the canine root was 10.16±0.81 mm. The mean length of the canal was 25.89±2.47 mm, and the infraorbital groove was 5.06±0.58 mm; and the mean angle between the IOC and the infraorbital groove was 153.20±3.28 degrees. In general, the distance of the IOC to the midpoint of the canine root on both the left and right sides was greater in males than in females, which was statistically significant on the left side (P<0.05). It was found that the length of the IOC and the angle between the IOC and the infraorbital groove on the left side had statistically significant correlations with age groups (P<0.05). The mean distance from the foramen to the infraorbital rim and the length of the IOC were proportional to the degree of nerve protrusion into the maxillary sinus; however, no significant correlation was found between the types of canals (degree of nerve protrusion) and gender.
Conclusion: Type 2 was the most common pathway of the IOC from the sinus roof. Although Type 3 was less common, due to the high risk associated with this type of canal, surgeons should be fully aware of the morphology and anatomical position of the IOC during sinus and orbital surgeries to reduce probable injuries.

Methods: This quasi-experimental study was conducted on 15 male participants who had undergone ACLR with a pronated foot (mean age= 23.2±4.5 years) and 15 healthy males (mean age= 22.7±4.3 years) in Ardabil, Iran during 2022. Plantar pressure values during gait with and without the use of anti-pronation insoles were recorded and compared using a foot scanner (sampling rate: 300 Hz).
Results: The effect of the group factor on the big toe plantar pressure variable was statistically significant (P<0.05). Pairwise comparison results demonstrated a significant increase in pressure in the ACLR group (154.63±41.71 N/cm²) compared to the healthy group (126.54±26.57 N/cm²) (P<0.05). Intragroup comparison results revealed a significant decrease in pressure on the second to fifth toes (215.73±60.74 N/cm²) and the first plantar (420.58±107.56 N/cm²) when using anti-pronation insoles compared to the non-insole condition (the second to fifth toes (201.57±76.21 N/cm²) and the first plantar (400.78±118.20 N/cm²) in the ACL reconstruction group (P<0.05).
Conclusion: The use of anti-pronation insoles can effectively reduce plantar pressure after ACLR in individuals with a pronated foot during gait.

Methods: In this experimental study, 30 female Wistar rats were randomly allocated into five groups of six: Control, methamphetamine, methamphetamine + aerobic exercise, methamphetamine + berberine, and methamphetamine + aerobic exercise + berberine. Intraperitoneal injections of methamphetamine (10 mg/kg) and aerobic exercise and berberine consumption (100 mg/kg) were administered for 4 weeks during the withdrawal period. The expression levels of dopamine 5 receptor and PARP genes was measured using real-time polymerase chain reaction (PCR).
Results: There was no significant difference in PARP gene expression between the methamphetamine group (1.02±0.65) and the control group (1.02±0.24). Similarly, there was no significant difference in dopamine 5 receptor gene expression between the methamphetamine group (5.74±4.94) and the control group (4.76±2.63). The expression levels of PARP and dopamine 5 receptor genes following exercise (1.01±0.55 and 4.30±1.96, respectively), berberine supplementation (0.61±0.25 and 2.97±1.45, respectively), and the combined intervention (0.67±0.30 and 3.43±1.87, respectively) showed no significant differences between the groups.
Conclusion: Short-term methamphetamine induction did not induce significant changes in the expression of dopamine 5 receptor and PARP genes in the hearts of methamphetamine-exposed rats.

Methods: This clinical trial was conducted on 101 students (44 girls and 57 boys) aged 13 to 15 experiencing musculoskeletal pain in various body parts in Bandar Mahshahr, Khuzestan Province, during the second half of the academic year 2021-2022. Participants were selected based on the Adolescent Nordic Musculoskeletal Questionnaire (NMQ), considering only the first question regarding the presence or absence of pain in each of the nine body regions (neck, shoulder, elbow, hand, upper back, lower back, pelvis, knee, and ankle) in the past seven days. A score of 1 was assigned to the presence of pain and 0 to the absence of pain. Participants were randomly assigned to two groups of 60: A control group and an intervention group. The intervention group performed corrective exercises at home for eight weeks, with three sessions per week, each lasting 40 minutes. No intervention was provided to the control group. Musculoskeletal pain levels in the neck, shoulder, upper back, elbow-arm, wrist, lower back, knee, and ankle were then compared in the pre-test, post-test, and follow-up.
Results: The mean and standard deviation of the total pain scores for the intervention and control groups were 1.32±0.41 and 1.33±0.46 in the pre-test, 1.01±0.08 and 1.34±0.46 at the post-test, and 1.17±0.36 and 1.11±0.31 at follow-up, respectively. Results revealed that eight weeks of corrective exercises significantly reduced musculoskeletal pain levels in the students’ neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, pelvis, and thigh (P<0.05); however, this improvement was not sustained at the follow-up.
Conclusion: Performing corrective exercises reduced musculoskeletal pain levels in the neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, and pelvis and thigh of 13-15-year-old students; however, the benefits were not sustained when the exercises were stopped.

Methods: This clinical trial was conducted on 111 patients with ACS divided into three 37-people groups: A control group (receiving routine education), the first intervention group (receiving education and a booklet), and the second intervention group (receiving education, a booklet, and SMS reminders). The study was conducted in patients at the coronary care units (CCUs) and post-CCUs of the following educational therapeutic centers: Shahid Sayyad Shirazi in Gorgan, the Fifth Azar in Gorgan, Amir Al-Momenin in Kordkuy, and Al-E-Jalil in Aqqala, Iran, during 2019. The research instrument consisted of the Treatment Adherence Perception Questionnaire (TAPQ) in three domains, including dietary regimen, medication regimen, and exercise and activity, which was completed at the time of discharge and two months later.
Results: The mean scores of adherence to treatment dietary in patients with ACS two months after discharge in the three domains of dietary regimen, medication regimen, and exercise and activity were significantly higher in the group receiving education and SMS reminders (105.54±75.8, 16.00±2.71, and 23.67±3.85, respectively) compared to the education group (84.73±5.02, 11.05±1.69, and 17.45±2.48, respectively) (P<0.05). Moreover, the scores in the three investigated domains were significantly higher in both intervention groups compared to the control group (82.68±13.54, 11.40±1.96, and 17.67±5.04, respectively) (P<0.05).
Conclusion: The use of education and a booklet along with SMS reminders to patients with ACS discharged from the hospital increased adherence to treatment. This adherence was higher in the intervention group receiving SMS reminders.

Methods: This clinical trial was conducted on 16 patients (12 males and 4 females) with unilateral amblyopia, with a mean age of 30±5 years referring to the clinics of Khatam al-Anbia Eye Hospital, Mashhad, Iran, during 2016-17. Patients were randomly selected from those with unilateral amblyopia (refractive, strabismic, or mixed) who had not responded to conventional treatments (patching or penalization). The healthy eye was considered a control. The therapeutic intervention consisted of four rTMS sessions at two-week intervals. Visual acuity and contrast sensitivity were measured and compared three times: Before the intervention, at the first session of intervention, and at the fourth session of intervention.
Results: The mean visual acuity at baseline (0.36±0.19) was not significantly different compared to the first treatment session (0.41±0.1); however, a significant increase was observed compared to the fourth session (0.45±0.23) (P<0.05). The mean contrast sensitivity at baseline (2.02±0.74) was not significantly different compared to the first (1.97±0.63) and the fourth (2.16±0.94) treatment sessions.
Conclusion: In most follow-ups, improvement in contrast was not observed in patients with treatment-resistant amblyopia at older ages using rTMS. Only an improvement in visual acuity was observed in the last follow-up compared to the baseline in the patient group.

Methods: This descriptive study examined the antifungal activity of various extracts from the aerial parts of Artemisia khorassanica, Artemisia scoparia, and Artemisia vulgaris against fungal isolates of Trichophyton rubrum, Trichophyton verrucosum, Microsporum canis, and Epidermophyton floccosum. The aerial parts of the three Artemisia species were extracted using five solvents: petroleum ether, dichloromethane, ethyl acetate, ethanol, and 50% hydroethanol. The extracts were screened for antidermatophytic effects against the fungi mentioned above, and the minimum inhibitory concentration (MIC) was determined using the agar dilution method. The most active extracts underwent preliminary phytochemical testing.
Results: In the initial screening, Microsporum canis and Trichophyton verrucosum showed the highest sensitivity (86.66%) and resistance (100%) to the tested extracts, respectively. Extracts from Artemisia scoparia exhibited the broadest range of activity. The most effective extracts, with an MIC of 78.12 µg/ml, were also from this plant. Hydroethanol extracts from all plant species demonstrated the least antidermatophytic activity. Preliminary phytochemical studies revealed the presence of terpenoids in all petroleum ether and dichloromethane extracts of the plant species.
Conclusion: Some lipophilic compounds, particularly in the petroleum ether and dichloromethane extracts of Artemisia scoparia, exhibit significant in vitro antidermatophytic activity.

Methods: This descriptive-analytical study was conducted on 170 opium users (139 men and 31 women) who visited the Methadone Maintenance Treatment Center in Gorgan, Iran during 2022, selected through convenience sampling. The Stop Signal Task (SST) was used to assess participants' inhibitory response, and the Barratt Impulsiveness Scale (BIS) was used to measure impulsivity levels.
Results: The average overall impulsivity score was 67.8±11.85. The average correct responses were 45.09±5.67, incorrect responses were 4.51±3.95, and delays were 0.96±2.32. The mean response time to each stimulus was 1290±512.83 milliseconds. There was a statistically significant correlation between impulsivity dimensions and age, correct responses and education level, and response time for inhibitory control with age and education level (P<0.05). There was no statistically significant correlation between the various dimensions of inhibitory response and impulsivity (cognitive impulsivity, non-planning impulsivity, and motor impulsivity) and overall impulsivity.
Conclusion: Opium users are generally impulsive. Additionally, younger individuals and those with lower education levels are more impulsive compared to others.

Methods: This longitudinal study included 143 obese individuals (125 women and 18 men) with a mean age of 43.13±9.83 years who underwent bariatric surgery in Gorgan, Iran during 2013-19. Participants were invited to join the study via phone calls. Research variables (type of surgery, blood group, pre-surgery weight, and body mass index [BMI]) were extracted from patient records, and their current weight and waist circumference were measured and recorded. Weight regain was determined based on one of three different criteria: (1) regaining more than 25% of the maximum weight lost post-surgery, (2) regaining more than 10 kg from the minimum weight post-surgery, or (3) an increase of more than 5 BMI units from the lowest BMI post-surgery.
Results: Overall, 33% of individuals experienced weight regain, with 26.6% according to the first definition, 29.4% according to the second definition, and 18.2% according to the third definition. Men had a higher rate of weight regain (P<0.05). Additionally, 93.6% (44 cases) of those with weight regain had abdominal obesity. On average, 79.7% of participants who were 48 months post-bariatric surgery experienced some degree of weight regain. Individuals with a pre-surgery BMI of 50 or higher had a 2.69 times greater chance of weight regain compared to those with BMI lower 50 (P<0.05). The mean weight loss after surgery was significantly higher in individuals who experienced weight regain than those who did not (P<0.05). There was no significant statistical association between weight regain and the type of surgery, age, education level, marital status, or blood group.
Conclusion: Weight regain over time is a reality after bariatric surgery, indicating that this method is not a definitive cure for obesity. Therefore, long-term follow-up for weight control is crucial, especially for individuals with a pre-surgery BMI of 50 or higher or those who experienced significant weight loss post-surgery.

Methods: This descriptive-analytical study was conducted on 61 patients (29 men and 32 women) aged 20-50 years who visited the Gorgan Dental School Clinic, Iran during 2019. The DMFT index, encompassing Decay (D), Missing (M), and Filled (F) teeth, was calculated. Quality of life was assessed using the 36-item DIDL (Dental Impact on Daily Living) questionnaire, which covers five domains: dental appearance and aesthetics, oral comfort, overall oral and dental function, eating limitations, and dental and jaw pain. Scores were categorized into three groups: dissatisfied (below 0), moderately satisfied (0 to 7), and satisfied (above 7).
Results: The mean score for oral health-related quality of life was 5.14±0.229, indicating a relative level of satisfaction. Pearson's correlation coefficient between DMFT and oral health-related quality of life was -0.358, suggesting a significant inverse relationship between DMFT and quality of life (P<0.05). The mean DMFT score ranged from 0 to 28, with a mean of 9.36, and the most frequent scores were 7, 11, and 13, each accounting for 11.5% of the sample. The mean decay (D) score was 3.44, the mean missing (M) score was 1.98, and the mean filled (F) score was 3.93, with ranges of 0-12, 0-19, and 0-13, respectively.
Conclusion: The results of this study indicate an inverse impact of the Dental Caries Index on patients' quality of life. Oral health-related quality of life is a multifaceted construct that affects various aspects such as appearance, oral comfort, and eating limitations, which are critical components of overall quality of life and satisfaction.

Results: The total mental pain score was 121.15±42.41, with a range of 44 to 206. The total mental pain scores for men and women were 123.67±38.98 and 120.31±43.58, respectively. The "confusion" subscale had the highest average score, while the "fear of loneliness" subscale had the lowest average score. There was a statistically significant association between the total mental pain score and its subscales with the severity of the disease and the patient's educational level (P<0.05).
Conclusion: The mental pain scores of patients with neurofibromatosis were evaluated to be relatively unfavorable.

Methods: This descriptive-analytical study was conducted on 99 patients (34 men and 65 women) with ESRD who were candidates for starting or continuing dialysis with a catheter in the educational and therapeutic centers of Golestan Province, Iran during 2021-22. Transjugular catheters were placed for the patients, and after one year, variables such as age, gender, history of diabetes, history of hypertension, catheter placement site (right or left jugular), and antiplatelet medication use were evaluated concerning the performance of long-term catheters in providing adequate flow for hemodialysis.
Results: In 91 patients (91.9%), the one-year catheter performance was assessed as satisfactory. The age of 61.6% of the patients were over 60 years old. Sixty-nine patients (69.7%) had a history of hypertension, and 58 patients (58.6%) had a history of diabetes. Fifty-seven patients (57.6%) received antiplatelet medication. The catheters were placed on the right side in 82 patients (82.8%). Catheter performance in patients taking antiplatelet medication was non-significantly higher than in those not taking antiplatelet medicines.
Conclusion: The performance of long-term catheters in chronic hemodialysis patients with ESRD showed no significant correlation with age, gender, diabetes, hypertension, antiplatelet medication use, or the side of the jugular vein where the catheter was placed.

Methods: This experimental study was conducted on 30 adult male Wistar rats divided into three groups: control, intense resistance exercise (first experimental group), and fierce resistance exercise combined with glutamine supplementation (second experimental group). The exercise groups participated in a single session of resistance climbing on an inclined plane with 4 sets of 5 repetitions, 30 seconds of rest between repetitions, and 2 minutes of rest between sets. Glutamine supplement powder was dissolved in 100 ml of distilled water at a dose of 0.5 grams per kilogram of body weight and administered daily via gavage for 5 days. The expression of alpha and IIX isoforms of the myosin heavy chain gene was examined in the extensor digitorum longus muscle tissue.
Results: The relative expression of the alpha myosin heavy chain gene in the fast-twitch muscle fibers increased significantly in the first experimental group (1.93±0.298) and the second experimental group (1.65±0.195) compared to the control group (P<0.05). The relative expression of the IIX motor unit gene in the fast-twitch muscle fibers also increased significantly in the first experimental group (1.42±0.239) and the second experimental group (1.26±0.190) compared to the control group (P<0.05). The increase in the relative expression of the alpha myosin heavy chain gene in the first experimental group compared to the second experimental group was statistically significant (P<0.05). However, the increase in the relative expression of the IIX motor unit gene in the first experimental group compared to the second experimental group was not statistically significant.
Conclusion: Our study concludes that a single session of intense resistance exercise, with or without glutamine supplementation, significantly increases the relative expression of the alpha myosin heavy chain gene and the IIX motor unit gene in the fast-twitch muscle fibers of the extensor digitorum longus muscle in adult male rats. These findings provide valuable insights into the molecular
