The study aimed to evaluate fatty tissue fixation using microwave and different times of processing in breast samples. 132 fatty tissues were included in this study. Fixation of samples at room temperature in 10% Formal saline showed better results for cellular outlines, nuclear details, overall morphology and staining than samples fixed at room temperature in 10% Formaline. Fixation of samples under Microwave oven at (60°C) in 10% Formalin for 5 min showed better results than samples fixed for 7 min & 10 min under Microwave oven at (60°C) in 10% Formalin. Fixation of samples under Microwave oven at (60°C) in 10% Formal saline for 5 min showed better results for cellular outlines, nuclear details, overall morphology and staining than samples fixed for 7 min & for 10 min fixed under Microwave oven at (60°C) in 10% Formal saline. The microscopic results of fixation in 10% Formal saline under Microwave oven at (60°C) for 5 minutes were excellent for fatty tissues. In this study it was found that microwave processing considerably shortens the time for fixation of fatty tissues without a demonstrable decrease in section quality or interpretation.
Background In recent years, special attention has been focused on the use of natural adsorbents as an alternative to replace the conventional adsorbents, based on both the environmental and the economical points of view. The study aimed to produce natural absorbent (activated carbon) from two local agricultural wastes: mango seeds (MS) and date stones (DS) and their uses in removal of contamination from fluid nutrient. Chemical properties such as ash content, moisture content, carbon content percentage and percentage of methylene blue reduction of the two samples were investigated. Results The results of study indicated that activated carbon produced from both MS and DS samples have the same pH value of 7 (neutral).The ash content of activated carbon prepared from mango seeds and date’s stones was 9.7 and 9.5%, respectively.Our statistical analysis showed no significant difference (p ≥ 0.05)for ash determinations, while the moisture content of (19.5 and 19.9%) was found for mango seeds and date's stones, respectively. There was no significant difference at p > 0.05 for moisture content of the two samples. A significant difference was observed in carbon contents for mango seeds (61.4%) and date's stones (21.8%) at p ≤ 0.05). There was no significant difference at p > 0.05 for moisture content of the two samples. Statistical analysis showed significance difference (p ≤ 0.05) for carbon determination for both samples. The results also indicated that there was significant correlation between reduction in methylene blue and percentage of activated carbon. Conclusions Activated carbon produced from MS and DS was found to be very effective in color removal and of acceptable quality in pH, carbon content, ash content, moisture content and solubility.
Background: Breast cancer is the second leading cause of cancer death and a health problem worldwide. Secreted mucins are upregulated in ductal adenocarcinoma of the breast, however, the use of mucin as breast cancer biomarker has not been established before. This study aimed to determine the use of mucin level as a potential biomarker for breast cancer diagnosis. Materials and methods: This was a retrospective, cross-section study involving 40 women subjects with breast cancer. Mucin level was examined with a combination of Alcian blue/periodic acid Schiff (AB/PAS) technique applied to each specimen. The results obtained were statistically analyzed using SPSS.Results: Results of neutral mucin detection showed that among breast cancer subjects, 16 cases (40%) were neutral mucin score (+), 23 cases (57.5%) were neutral mucin score (++), and 1 case (2.5%) was neutral mucin score (+++). Meanwhile, 10 cases (25%) were acid mucin negative, 17 cases (42.5%) were acid mucin score (+), 11 cases (27.5%) were acid mucin score (++), and 2 cases (5%) were acid mucin score (+++). The most frequent type of mucin was the combination of acid and neutral mucin (30 cases; 75%) and neutral mucin were 10 cases (25%). Conclusion: Detection of mucin level can be used as an alternative technique for the diagnosis of breast cancer complementary to other types of special stains. Keywords: AB, PAS, breast cancer, histological grade, mucin level
Background: Moringa oleifera which is available in many areas all over the world including Sudan is low-cost and traditionally used in the treatment of many disorders, including malnutrition. This study aimed to determine the effect of aqueous extract of M. oleifera leaves in renal, liver functions and complete blood count (CBC) parameters, and its potential as therapy for malnutrition.Materials and methods: This was an experimental case control study using twenty-five Wistar albino rats. Rats were divided into three groups: normal protein diet group, low protein diet with or without M. oleifera extract groups. We determined rats' weight, CBC parameters, blood mineral concentrations, as well as liver and renal functions at day 0, 7, and 14.Results: Our findings showed that rats' weight were significantly different between the three groups at day 0, 7, and 14. Rats' weight, blood sodium, potassium, calcium, and urea concentration, as well as Hb concentration, TWBCs count, total platelets count, and %lymphocyte showed significant differences between three groups at day 0, 7, and 14.Conclusion: M. oleifera leaves can be used as potential therapy for malnutrition because they have some effects on weight, blood mineral concentrations, renal and liver function, as well as CBC parameters.Keywords: ALP, AST, ALT, creatinine, Moringa oleifera
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
