The neuroendocrine system controls animals' adaptability to their environments by releasing psychotropic compounds such as catecholamines [epinephrine (EP), norepinephrine (NE), and dopamine (DA)], corticosterone (CORT), and serotonin (5-hydroxytryptamine or 5-HT). Changes of these neuroendocrine compounds have been used as biomarkers of animals' stress responses associated with their well-bein...

X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starti...

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 b...

Mitral regurgitation (MR) is associated with increased neuronal release of norepinephrine (NE) and epinephrine (EP) into myocardial interstitial fluid (ISF) that may be necessary in sustaining left ventricular (LV) function via activation of cardiomyocyte beta-adrenergic receptors (ARs). However, activation of neuronal beta-ARs on cardiac neurons may lead to further catecholamine release, with ...

Background: Ectopic pregnancy (EP) is a common condition which presents a major health problem for women of childbearing age. This study aims to analyze and identify risk factors that have the potential for EP and evaluating the contribution of the risk factors associated EP. Materials and Methods: In this case control study, performed from 2006 to 2011 at Arash hospital, the casepatients were ...

ectopic pregnancy (ep) and miscarriage are important differential diagnosis of first trimester vaginal bleeding. in first trimester, serum progesterone value can be 5-20 ng/ml in ep and miscarriage. since delay in diagnosis of ep could have high mortality and morbidity, the aim of this study was comparison of serum progesterone value in ep and miscarriage in order to differentiate these conditi...

background: ectopic pregnancy (ep) is a prevalent problem and the most common cause of maternal mortality at the first trimester. results from different studies are not consistent regarding the risk factors associated with ep. the current study aimed to investigate about risk factors associated with ep in kermanshah-iran. methods: a case–control study conducted to compare risk factors of ep amo...
