universities of medical science and health services (umshss) are among the main organizations in iran's health-care section. improving their efficiency in financial resource management through creating an appropri-ate coordination between consumption and resources is strategically vital. investigating the financial performance as well as ranking the iranian umshss is the research objective.the ...

It has been shown that those factors which affect gastric acid secretion through the ventromedial and lateral nuclei of hypothalamus, can significantly alter centrally-mediated secretion. There is much evidence that glucose is among these factors that through a central mechanism can decrease induced acid secretion. It appears that this effect is mediated through glucose-sensitive neurons within...

objective(s):some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. incidence of these condition increases with aging. on the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (nos) activity is also altered in diabetes. in this study, modification in the enzyme activity associated with aging a...

noise is considered as one of the most severe sources of environmental and workplace constraints. many noise effects are well known on immune function, hormonal levels, cardiovascular and respiratory systems. in this study, our aim is to evaluate the effects of traffic noise exposure on basal and stimulated gastric pepsin secretion. 48 male rats were exposed to traffic noise (86 db) for a short...

the effect of epinephrine on triacylglycerol secretion was investigated in isolated rat hepatocytes. the effect appeared at concentrations of more than 1 µm and reached a plateau at 10 µm. epinephrine concentration for half of the maximal bioeffect (ec50) was about 1 µm. epineplrrine at a concentration of 10 µm suppressed triacylglycerol secretion by 33% and increased its cellular content by ap...

objective: endometriosis is a common disease in which the endometrial stroma and glands grow abnormally outside the uterine cavity. the establishment of animal models can be effective for determining the etiology of endometriosis. in this study we compare two endometriosis models using endometrial fragments and isolated cultured endometrial cells. methods: we obtained endometrial tissues that ...

Niwińska B., Andrzejewski M. (2017): Effects of selenium supplement forms on the diet–cow–calf transfer of selenium in Simmental cattle. Czech J. Anim. Sci., 62, 201–210. The aim of this study was to determine the efficiency of diet–cow–calf transfer of selenium (Se) depending on the forms of Se-supplement given to cows of Simmental breed during the last trimester of pregnancy and the first wee...

Recent studies have shown that genetic deficiency of the adipocyte fatty acid-binding protein (aP2) results in minor alterations of plasma lipids and adipocyte development but provides significant protection from dietary obesity-induced hyperinsulinemia and insulin resistance. To identify potential mechanisms responsible for this phenotype, we examined lipolysis and insulin secretion in aP2-/- ...

Objective(s): Arsenic, a toxic metal in drinking water and butyric acid (BA) is a free fatty acid found in many foods. These two can induce oxidative stress in some tissues. The present study investigated the protective effect of metformin against toxicity induced by Arsenic (As) and BA in isolated mice liver mitochondria and pancreatic islets. Materials and Methods: In this study, liver mitoch...
