Insulin-like growth factor 2 (IGF2) as a microglia-derived anti-inflammatory cytokine has a pivotal activity in memory consolidation. However, there is limited evidence on brain cell-originated IGF2 expression, regulation and function in pathological condition and neuro-inflammation. Hence, the present study was conducted to investigate the effect of IGF2 on improving the memory impairment in a...
تحقیقات اخیر روی روشهای عددی، بر ایده استفاده از روشهای بدون شبکه{meshfree methods} برای حل عددی معادلات دیفرانسیل با مشتقات جزئی تاکید می کند. یکی از ویژگی های رایج همه روشهای بدون شبکه، توانایی آنها در ساخت تقریب تابع، تنها با استفاده از اطلاعاتی در یک مجموعه از داده های پراکنده می باشد. تعدادی از روشهای بدون شبکه عبارتند از: روش هیدرودینامیکهای ذره ی هموار{smooth particle hydrodynamics ...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
OBJECTIVE Letrozole and estradiol valerate are used to treat some hormonally-responsive symptoms and also in modeling of the polycystic ovary syndrome. However, the stereological analysis of the ovary has received less attention. Estimation of the whole ovary volume using the Cavalieri method can be applied in any orientation desired, but estimation of the mean volume of the oocytes requires is...
هدف از ارایه این پایان نامه بررسی روشی است برای حل معادلات دیفرانسیل غیرخطی که شکل عمومی آنها بصورت lu+nu=g(t) می باشد. در این معادله n یک عملگر غیرخطی و l یک عملگر دیفرانسیلی خطی می باشد. این روش تحت عنوان روش تجزیه (آدومیان) بررسی می شود. در این روش u رابه صورت u تجزیه می کنیم. همچنین ترکیب غیر خطی nu را بصورت an (u , u , ... , u ) نمایش می دهیم که a ها چند جمل...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Background and Objective: Metformin is a widely used medicine for treatment of type 2 diabetes. In this study, the effect of various doses of metformin on the mouse islets of langerhans volume was investigated. Materials and methods: Twenty four C57BL/6 adult male mice weighting 30±5 gr were randomly divided into 4 groups. Normal saline was given to the control group (group 4) and the experimen...
Bu çalışmada ratlarda medulla spinalis’in thoracal bölümünün ak ve gri madde tüm dokunun hacim yoğunlukları stereolojik yöntem kullanılarak araştırıldı. Materyal olarak 1 5 aylık olmak üzere iki farklı yaş grubundan altışar adet erkek Wistar Albino ırkı ratlar kullanıldı. Van Yüzüncü Yıl Üniversitesi Tıp Fakültesi Deney Hayvanları Yetiştirme Araştırma Merkezi’nden ölü temin edilen materyaller %...
Introduction: The use of stereological methods in evaluation of volume changes in vital organs such as kidney is very important. In this study, the volume of glomeruli in glycerol-induced acute renal failure in rats was determined. Methods: 48 Sprague-Dawley male rats were divided into 2 groups (1control, 1experiment). Experimental group was injected 10ml/kg of 50% glycerol intramuscularly,...
