In addition, methyl and ethyl esters were prepared from rapeseed and sun¯ower oils using the same catalysts. Chemical composition of the esters was determined by HPLC for the class of lipids and by GC for fatty acid compositions. The bio-diesel esters were characterized for their physical and fuel properties including density, viscosity, iodine value, acid value, cloud point, pure point, gross heat of combustion and volatility. Methyl and ethyl esters prepared from a particular vegetable oil had similar viscosities, cloud points and pour points, whereas methyl, ethyl, 2-propyl and butyl esters derived from a particular vegetable oil had similar gross heating values. However, their densities, which were 2±7% higher than those of diesel fuels, statistically decreased in the order of methyl $ 2-propyl > ethyl > butyl esters. Butyl esters showed reduced cloud points ()6°C to)10°C) and pour points ()13°C to)16°C) similar to those of summer diesel fuel having cloud and pour points of)8°C and)15°C, respectively. The viscosities of bio-diesels (3:3±7:6 Â 10 À4 Pa s at 40°C) were much less than those of pure oils (22:4±45:1 Â 10 À4 Pa s at 40°C) and were twice those of summer and winter diesel fuels (3.50 and 1:72 Â 10 À4 Pa s at 40°C), and their gross heat contents of approximately 40 MJ/kg were 11% less than those of diesel fuels ($45 MJ/kg). For dierent esters from the same vegetable oil, methyl esters were the most volatile, and the volatility decreased as the alkyl group grew bulkier. However, the bio-diesels were considerably less volatile than the conventional diesel fuels.

The authors, however, are overlooking the more common and most likely infectious disease of unknown etiology today-prostatitis. According to the pathologist McNeal, the prostate gland is the most commonly diseased internal organ of the human body (2). Prostatitis is the most common prostate disease, resulting in more physician visits than either benign prostatic hyperplasia or prostate cancer, according to the National Institutes of Health (3). Despite its frequency, prostatitis as a disease and as a histologic lesion is understudied (4). By the Meares and Stamey culture localization procedure, in which the first voided urine, a midstream urine, the expressed prostatic secretions, and a final voided urine are compared, more than 90% of cases in patients with chronic pelvic symptoms are labeled as "nonbacterial" prostatitis or prostatodynia, both of which are thought to be incurable diseases (5). The University of Washington has documented white blood cell counts as high as 38,000 per mm 3 , in "nonbacterial" prostatitis patients (6). According to urologist Thomas Stamey, up to 50% of all men experience symptoms of prostatitis during

It was first announced in Wuhan, China in December 2019 but started to spread globally by late January 2020. COVID-19 pandemic and subsequent global spreading poses additional danger to healthcare personnel particularly the laboratorians. Other health practitioners may engage patients by observing social / physical distancing, but how laboratory staff observe or apply same rule to infectious samples remain a notable question. Activities of laboratorians result in repeated exposure at close interactions to patient’s samples including SARS-CoV-2 infected specimens, which make them susceptible to COVID-19. Therefore, it is imperative to review mitigating measures in restraining possible exposure and spreading of SARS-CoV-2 in the best interest of laboratory staff and pathologists. It i...

Parasites are creatures that invade a host, attach themselves externally and internally (to tissues and organs), and rob the host of nutrients. Symptoms may occur immediately or take up to 20 years for symptoms to manifest. Why in some cases it could be asymptomatic. The presentation of signs and symptoms in some food and take anthelmintic at least one time diseases may involve with helminthic infection. If you are sick with unknown cause, helmenthic infection should be concern. Protection from helminthic infection by eating cooked.

This situation has led to the search for an alternative fuel, which should be not only sustainable, but also environmentally friendly. Biodiesel is a clean burning renewable fuel made from vegetable oils, animal fats and recycled cooking oils and greases. It is an amber yellow liquid. The manufacturing process for biodiesel combines oils and fats with methanol and a catalyst to produce Fatty Acid Methyl Esters (FAME) which is commonly referred to as biodiesel. Vegetable oils such as rapeseed, canola, soybean and palm oils are the most common raw materials for biodiesel production. The aim of this work was to prepare and characterize biodiesel from soya-bean (a commercial vegetable) oil. To achieve this aim, the following objectives were focused on: To prepare biodiesel from a refined commercial oil, To separate the by-product (glycerol) from the bi...

The genes are in each cell. Normally, the cell in our bodies replace themselves through an orderly process of cell growth: healthy new cells take over as old ones die out. A tumor can be benign (not dangerous to health) or malignant (has the potential to be dangerous). Benign tumors are not considered cancerous: their cells are close to normal in appearance, they grow slowly, and they do not invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous. Left unchecked, malignant cells eventually can spread beyond the original tumor to other parts of the body. Breast cancer can be defined as a malignant tumor of breast usually associated with painless lump in the breast usually associated with painless lump in the breast. Available evidence suggests that breast cancer in most parts of Africa is the leading cause of mortality associated with cancers in African women. Recent global cancer statistics indicates rising global incidence of breast cancer with faster increase occurring in developing countries. To determine the histopathologic cell changes in breast cancer using breast disease tissue blocks in Enugu State University Teaching Hospital 2009-2013. Most women with breast cancer seek medical help at the terminal stage of the disease. This may be a contributory factor to increased number of patient having invasive ductal carcinoma (IDC) as seen in the study. The results of this study suggest that breast cancer is increasing in Nigeria and needs an urgent intervention measure. Cancer cells are treatable if only detected early enough, our findings reveals that breast

The use of herbal medicine is on the increase globally, hence the increased interest on research on herbal formulations and preparations. Some of these plants are used as condiments and ingredients in food thus referred to as local spices. One of such plants used as a local spice in Nigeria is Piper guineense traditionally called 'Uziza' amongst the Igbo tribe, 'Iyere' amongst the Yoruba tribe, 'Etinkene' amongst the Efik and Ibibio tribe and 'Ebe-ahinhi akpoke' amongst the Edo tribe. The leaves and seeds of Piper guineense were initially consumed in the Southern part of Nigeria. The aim of this research is to detect and demonstrate any histological effect of Piper guineense leaves on the liver of Wistar rats and on after shave rash in human. During the acclimatization period which lasted for two (2) weeks, three rats died due loss of appetite, emaciation, weakness, dislocation of neck with head leaning to the right, consistent rolling over and vigorous twirling in circular motion during carriage. After two weeks of acclimatization, the rats weighed; The Piper guineense leaves was able to effect total removal of the rash when used on the consented individual within day 3 and day 4 of usage. Piper guineense leaves when taken into reasonably consideration causes no histological changes of the liver tissues, hence its use should be encouraged both for consumption and in treatment of pseudofolliculitis Barbae (after shave rash).

It constitutes a major health concern today because the prevalence has continuously increased worldwide over the past few decades affecting about 2.8% of the world population. This study examine the palliative effect of daonil supplemented with tryptophan on alloxan induced diabetic rats and the possible benefit of the treatment. Since carbohydrate metabolism is modified in diabetic animals, it's of interest to determine the effect of tryptophan on alloxan induced diabetic rat. To identify possible relationships between tryptophan with diabetes. The purpose of this study was to ascertain if tryptophan administration has positive effect on the glucose level. Twenty five healthy female rats out of 30 were made diabetic by dissolving 150mg alloxan monohydrate per kg weight in 0.9ml of normal saline which was injected into the rats intraperitoneally. After the establishment of diabetes the animals were subdivided into three groups of 4 each. Daonil and tryptophan only were administered orally to group 1 daily for 7 days, Tryptophan only for group 2 and daonil only for group 3 while the group 4 of five served as controls. Tryptophan was administered at 400mg/kg and 0.5ml of daonil. The weight of the animals were recorded, and the glucose levels was determined using the glucometer on the the 3rd and 7th day. Histomorphological studies were conducted on the kidney, liver and pancreas tissues using light microscope method. Daonil and tryptophan treated rats (group1) and Tryptophan only treated rats (group 2), showed no significant decrease (P<0.318) in glucose level. Treatment with daonil showed a significant decrease (P>0.01) in weight and glucose concentration. The histomicrograph .for the three treatments showed that the kidney renal corpuscles appeared as atrophied dense rounded structures bounded by inflammatory infiltrates. Liver show thickened distorted portal vein with clear visible fatty hydropic changes and congested with some visible inflammatory cells. Pancreas pyknotic nuclei of some acinar cells appeared normal with some islet-cells showing congested pyknotic nuclei with lymphocytic infiltrates. The findings in this study indicate that diabetes had deleterious effect on the kidney, liver and pancreas due to drug administration and also tryptophan supplement was not a good alternative for diabetes management.

They were acclimatized to their environment for 2 weeks during which they were fed with standard pelleted feed and water. The study is divided into acute toxicity testing and main experimental phase. The acute toxicity testing for the determination of the median lethal dose was ascertained using 12 rats divided into groups K, L, M. The main experiment using 18 rats divided into groups A, B, C, D, E and F of three (3) rats in a group in different cages, cage A served as control. The rats were orally administered graded doses of Indocid dissolved in water once daily along with their feed for 30 days. Cages B-F received 3.0, 2.5, 2.0, 1.5 and 1.0 mg/kg respectively and were closely observed. At day 31, the rats were randomly selected, sacrificed, the stomach, and small intestine were excised, examined grossly and subsequently processed for light microscopy. Grossly the org...

Twenty four (24) of this blocks representing 66.6 % were from male patients while the other twelve (12) representing 33.3 % were from female patients. All the cases were diagnosed as osteosarcoma between January 2010 and June 2016. Five (5) out of the 36 blocks were used as controls. Duplicate (2) sections were made from each block and stained with H &E as well as Highman’scongo red technique. In demonstrating amyloid deposit, in the 36 test samples, 13.8% were positive for amyloid with H &E while 11.1% of the total 36 test samples were positive for amyloid with Highman’s Congo red technique. This test result shows a low incidence of amyloidosis in osteosarcoma. In addition, Congo red showed greater specificity, eliminating false positive result, hence a better stain in all amyloid study.
