The experiments were conducted in three replicates with six treatments (four Pseudomonas strains, AMF and control) and three rates of P-fertilizer (0, 75, 150 kg P ha-1). Application of higher phosphate rates decreased total antioxidant capacity, total phenolic and flavonols content, whereas AMF and Pseudomonas strains increased quality and P concentration of fruit. The use of AMF and Pseudomonas strains resulted in better quality when used along with 75 kg P ha-1. These results demonstrated that the rhizospheric microorganisms improved the quality of fruit, especially when they applied in combination with lower rates of chemical fertilizers. Therefore, application of these microorganisms in sustainable agriculture is recommended.

[ 125 I]Epidepride, which binds with high affinity to DA D 2 and D 3 receptors, was used in autoradiographic studies to determine the distribution and density of D 2-like receptors, and the epidepride analogue [ 18 F]fallypride positron was used for positron emission tomography studies to delineate D 2-like receptors in vivo. Both approaches revealed a heterogeneous distribution of thalamic D 2/3 receptors, with relatively high densities in the intralaminar and midline thalamic nuclei, including the paraventricular, parataenial, paracentral, centrolateral, and centromedian/parafascicular nuclei. Moderate densities of D 2/3 sites were seen in the mediodorsal and anterior nuclei, while other thalamic nuclei expressed lower levels of D 2-like receptors. Most thalamic nuclei that express high densities of D 2-like receptors project to forebrain DA terminal fields, suggesting that both the thalamic neurons expressing D 2-like receptors and the projection targets of these neurons are regulated by DA. Because the midline/intralaminar nuclei receive prominent projections from both the ascending reticular activating core and the hypothalamus, these thalamic nuclei may integrate activity conveying both interoceptive and exteroceptive information to telencephalic DA systems involved in reward and cognition.

These models also provide accurate representation of dynamic heart anatomy, helping practitioners determine their procedural approach and select proper device sizing. While the efficacy of 3D models obtained from Computed Tomography and Transesophageal Echocardiography over 2D Transesophageal Echocardiography imaging for WATCHMAN procedural planning has been demonstrated, this project aims to directly compare 3D Computed Tomography versus 3D Transesophageal Echocardiography and determine which is more favorable. Computed Tomography and Transesophageal Echocardiography 2D imaging studies from patients that underwent LAA WATCHMAN closure device implantation we used as templates for 3D cardiac models. These 3D models were scored using a 10-point Likert questionnaire. Scoring was conducted by a diverse team that included cardiologists, research specialist...

A pre- and post-survey administered to participants showed increased knowledge and improved impressions of cardiology. The students ranked the experience as high quality. This project suggests that similar elective experiences could enhance education during the preclinical period of medical education. Key words: medical education, cardiology, technology, imaging, echocardiography

Forming durable ohmic contacts to these films is vitally necessary for the effective performance and long life of almost all such devices. Silver electrodes are commonly considered as low resistance ohmic contacts to many metal-oxide semiconductors. Particularly in devices operating at elevated temperatures, silver migration can considerably decrease useful device lifetime. Here, we study the performance of silver electrodes paste printed on SnO2 thin films and show that the I-V characteristics of the silver/SnO2 contact changes with operating time at elevated temperatures. SnO2 films are grown on alumina substrates by ultrasonic spray pyrolysis technique. A pair of Ag electrodes are paste-printed on the surface of the grown films followed by a heat-treatment step to stabilize the deposits. The as-fabricated Ag/SnO2 contacts present ohmic characteristics. Continuous application of DC voltages to the samples operating at 350 °C results in a significant drop in the devices' resistance. The results originate from field-assisted migration of silver ions from the anode to the cathode electrode and formation of Ag micro-filaments in the polycrystalline SnO2 layer.

Cardiopulmonary failure is the most common cause of death in thyroid storm. Clinicians should keep in mind that thyroid storm complicated with cardiopulmonary failure can be the first presentation of thyrotoxicosis. As early intervention is associated with improved patient outcome, prompt diagnosis based on clinical grounds is of paramount importance in the management of thyrotoxicosis. A high index of suspicion and the ability of early recognition of impending thyroid storm depends on a thorough knowledge of both the typical and atypical clinical features of this illness. Herein, we report a case of thyroid storm presenting as cardiopulmonary failure in a 51-year-old woman with undiagnosed Grave's disease. Additionally, we review the pathophysiology of cardiopulmonary failure associated with thyrotoxicosis and various treatment modalities for thyroid storm.

Previous studies revealed that this drug may reduce nitric oxide (NO) in an in vitro inflammatory model. The aim of the present study was to investigate the anti‑inflammatory effect of Migri‑Heal® on primary mix glial cells stimulated with LPS. In the current study, neonatal rat primary mix glial cells were isolated from the mixed glial cultures via shaking, and cultured in Dulbecco's' modified Eagle's medium supplemented with 10% fetal bovine serum. Following pretreatment with Migri‑Heal® (25, 75, 100, 150, 200 and 300 µg/ml) and cells were treated with LPS (10 µg/ml) for 1 h, and incubated for 48 h. The present study determined that 150 µg/ml Migri‑Heal® significantly reduced the production of NO in rat mix glial cells stimulated with 10 µg/ml LPS. Migri‑Heal® also suppressed mRNA expression level of LPS‑induced inducible nitric oxide synthase and tumor necrosis factor α, ...

MicroRNA-149 (miR-149) was recently demonstrated to function as a tumor suppressor gene in glioblastoma multiforme (GBM). However, the potential linkage of miR-149 levels and the underlying epigenetic regulatory mechanism in human GBM has not been studied. We used quantitative real-time polymerase chain reaction to investigate the levels of miR-149 in GBM tissues, their matched adjacent normal tissues, and glioblastoma U87MG cell line. Using bisulfite genomic sequencing technology, DNA methylation status of upstream region of miR-149 was evaluated in study population groups and the U87MG cell line. After treatment of cells with 5-aza-2'-deoxycitidine (5-aza-dC), the DNA methylation status, gene expression, and target protein levels of miR-149 were investigated. Our studies revealed that methylation and expression levels of miR-149 were significantly increased and decreased, respec...
