background: it has been reported that the chronic oral administration of garlic homogenate protected the rat heart from in vitro ischemic reperfusion injury. however, the biological effects of garlic juice on the heart are expected to be different from oral administration of it. objective: the present study was designed to investigate the effect of garlic juice on the isolated rat heart in isch...
background and objective : sleep deprivation (sd) is caused by a host of reasons and has numerous consequences on cardiac system. in this study, we aimed to assess the preconditioning effects of acute sd on ischemia (is)-induced ventricular arrhythmias in isolated rat hearts. materials and methods : male wistar rats randomly were placed into the four groups: is-group, acute sd group, control gr...
in the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. the hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. in the control group, the hearts were perfused by normal drug free krebs-henseleit (k/h) solution t...
Acetaldehyde is a major metabolic product of ethanol and is found in high concentrations in the serum during alcohol abuse. The effects of acetaldehyde on isolated rat liver cells and on purified hepatocyte plasma membrane vesicles have been studied. In concentrations of 0-10 millimolar acetaldehyde has been shown to have no detectable effect on either hepatocyte metabolism or gross membrane fu...
Stem cell-derived hepatocytes may be an alternative cell source to treat liver diseases or to be used for pharmacological purposes. We developed a protocol that mimics mammalian liver development, to differentiate cells with pluripotent characteristics to hepatocyte-like cells. The protocol supports the stepwise differentiation of human embryonic stem cells (ESC) to cells with characteristics o...
docetaxel (dtx) is one of the most widely used drugs in oncology due to its high efficacy against several cancers. though, its routine clinical administration, formulated in tween 80, causes serious side effects. polylactide-co-glycolide (plga), biodegradable polyester synthesized and approved for human use, is employed to overcome this problem. in this investigation, we compare the cytotoxic m...
Recently, sandwich-cultured (SC) rat hepatocytes have been used as an in vitro model to assess biliary excretion of drugs and xenobiotics. The purpose of the present study was to validate the use of SC rat hepatocytes for the in vitro assessment of P-glycoprotein (P-gp)-mediated biliary drug excretion. The specific and fluorescent P-gp substrate rhodamine 123 (Rh123) and the P-gp substrate digo...
UNLABELLED Liver tissue engineering with hepatic stem cells provides a promising alternative to liver transplantation in patients with acute and chronic hepatic failure. In this study, a three-dimensional (3D) bioscaffold was introduced for differentiation of rat bone marrow mesenchymal stem cells (BMSCs) into hepatocytes. For hepatocyte differentiation, third passage BMSCs isolated from normal...
Na+/H+ exchanger (NHE) isoforms play important roles in intracellular pH regulation and in fluid absorption. The isoform NHE3 has been localized to apical surfaces of epithelia and in some tissues may facilitate the absorption of NaCl. To determine whether the apical isoform NHE3 is present in cholangiocytes and to examine whether it has a functional role in cholangiocyte fluid secretion and ab...
objective: diabetes is an important risk factor for cardiovascular events. the great percent of morbidity in patients with diabetes is due to endothelial dysfunction. the present study investigated the effects of hydroalcholic extract of nigella sativa (n. sativa) on contractile and dilatation response of isolated aorta in streptozotocin (stz)-induced diabetic rat. materials and methods: rats ...
