Knowledge of sex differences in the histomorphology of the human carotid body (HCB) is important in explaining the differences in respiratory function, responses and disease predisposition.1,2 Functionally, there are sex differences in the ventilatory response to hypoxia (VRH) and hypercapnia,1,3‒5 response in ventilatory control under acute or chronic hypoxic stimulation;6 morphine induced ven...

an experiment was conducted to study the effects of enzyme and phytogenic product (thymol+carvacrol) on the ileal microbial population and jejuna and ileal histomorphology of broilers fed wheat based diet. the experiment was conducted as a 2 × 3 factorial arrangement with 2 levels of enzyme endofeed w (0 and 0.05%) and 3 levels of next enhance 150® (0, 100 and 200 mg/kg). each of the 6 dietary ...

Quantum dots are new types of fluorescent materials for biological labeling. As a result, QDs toxicity study is an essential requirement for future clinical applications. Therefore, the cytotoxic CdSe:ZnS quantum dots effects on some organs in mice are presented in this study. In this work, 10, 20 and 40 mg/kg doses of CdSe:ZnS quantum dots were injected to 32 adult male mice. Structural and op...

Introduction: The impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male Wistar rats (80-100 g body weight). Material & Method: It was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight a...
