We characterized the absorption, distribution, metabolism, and excretion of tetrabromobisphenol A (TeBBPA) in C57BL/6 mice. After TeBBPA dosing, we monitored mice collected samples for 24 h. Most was excreted feces at 12 At h, 71% administered found TeBBPA-conjugates were detected 17.8%. also debrominated metabolites TeBBPA, including tribromobisphenol (TriBBPA), dibromobisphenol (DiBBPA), mono...

Congenital extra hepatic port systemic shunt, is a rare clinical entity which can lead to hepatopulmonary syndrome wherein blood from portal vein directly drains into circulation, causing an alteration in metabolism of pulmonary vasoactive substances, vasodilatation, diffusion-perfusion defects, and eventually, arterial hypoxemia due either increase vascular resistance or the creation arteriove...

The first well-recognized CBF studies on humans were performed by Kety and Schmidt in the 1940s using nitrous oxide (N2O) gas. The measurement of CBF was based on the principle that the rate of uptake and clearance of an inert diffusible gas is proportional to blood flow. The tissue concentration of the tracer at equilibrium must therefore be dependent on blood flow rather than diffusibility. T...

the aim of present study is investigating effect of treated lemon pulp by saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. in this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by saccharomyces cerevisiae yeast on protein recei...

Tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. Glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. Human glucose tolerance declines as day comes into night. Based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...

Background: Splenectomy is a common treatment for beta thalassemia. It not only eliminates many complications by reducing the need for blood transfusion, but also causes new complications that threaten the patientschr('39') health. The aim of this study was to determine if splenectomy could alter the lipid profile and glucose metabolism in beta thalassemia major patients. Methods: In this case-...

Measurement of myocardial blood flow for research studies and in clinical practice has enhanced our understanding of the coronary circulation in health and disease. Despite the refinements in measurement techniques of epicardial coronary anatomy provided by quantitative angiographic techniques and, more recently, by intravascular ultrasound, direct measurement of coronary blood flow provides im...

conclusions ramadan fasting resulted in weight loss even it was only a temporary effect, as the weight was quickly regained within one month after fasting. the catabolism catabolic state, which is related to protein loss, was not triggered during ramadan fasting. further research is needed to evaluate the effects of weight loss during ramadan fasting in healthy individuals. results by the 28th ...

a study of the relationship between the disorder of glucose metabolism and ischemic heart disease was performed on 122 patients and 100 controls in loghman-dowleh adham’s medical center in tehran. the gtt abnormality was found in only 8% of the control group while for the patients with the heart ischemia the prevalence was 62.3%. prevalence of glucose metabolic disorder among men with acute myo...

Branched-chain amino acids (BCAA) are used in attempts to reduce blood ammonia in patients with cirrhosis and intermittent hepatic encephalopathy based on the hypothesis that BCAA stimulate muscle ammonia detoxification. We studied the effects of an oral dose of BCAA on the skeletal muscle metabolism of ammonia and amino acids in 14 patients with cirrhosis and in 7 healthy subjects by combining...
