Chemical cues and pheromones mediate fish reproduction, aggregation, risk assessment, kin recognition. To better understand the chemical communication of conspecific fish, behavioral responses to bile acids (BAs), their source, reception investigated in large yellow croaker (Larimichthys crocea). Behavioral experimental results indicated that juvenile were attracted intestinal contents (ICs) em...
Abstract Background and objectives: Bile in healthy people is a sterile fluid and presence of any microorganism can be a marker for a disorder like cholelithiasis. The aim of this study was to determine the frequency of bacterial agents in the bile of patients with bilestone, malignant pancreatic and biliary diseases. Material and Methods: One hundred and two bile samples were obtained, during ...
The aim of this study was to examine the effect of crude bile on the human HepG2 and CCRF-CEM cell lines. Cells were exposed to different dilutions of bile. Antiproliferative effects were determined by the cytotoxic MTT assay. Cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Bile administration resulted in dose-dependent c...
In this study the LC50 96h values of water-soluble fractions (WSF) of the Caspian Sea ? exploited crude oil were determined in beluga, Huso huso fingerlings. The fingerlings averaged 2.42 ? 0.11 g in weight were exposed to WSF crude oil at concentrations 24.75, 27, 29.25, 31.5, 33.75, 36, 38.25 ppm. The treatments were performed in three replicates and all changes in the specimens were determin...
Nonacclimated and Cu-acclimated rainbow trout (Oncorhynchus mykiss) exhibited equally rapid clearance of a single bolus of injected (64)Cu (3,780 nmol/kg) from the plasma (32-40 min to half- concentration). Eight hours after Cu injection, approximately 80% of the injected Cu was found in the liver. However, when Cu labeled with (64)Cu was presented intravascularly via continuous infusion at a r...

To assess whether lipid peroxidation of hepatic mitochondria is associated with cholestatic hepatic injury we examined the effect of bile duct ligation (BDL) versus sham surgery on mitochondrial lipids of rats maintained on one of seven diets. Diets included vitamin E-deficient (E-) and vitamin E-sufficient (E+) combined with normal lipid (11.9% calories as stripped corn oil), high lipid (35% c...
Introduction: Increase in the common bile duct diameter after cholecystectomy has been reported in animal model. However, similar studies in the human resulted in controversy. Methods: Between 2008 and 2012, fifty two patients with clinical as well as radiological signs and symptoms of gallbladder disease were enrolled in this study. The patients underwent laparoscopic and open cholecystectomy ...
ABSTRACT Background and Objective: In this study, we compared the susceptibility of Salmonella typhimurium phoP mutant and its parent to stress conditions that the pathogen may encounter in a host. Methods: For this purpose, we used the phoP deletion mutant constructed in our previous study. In order t...
In October 2007, a light crude oil spill took place in the off shore Kab121 oil well, 32 km north of the mouth of the Grijalva River, Tabasco, Mexico. In order to estimate the possible effects of oil spill on the biota in the area surrounding the spilled well, the level of different fractions of petroleum hydrocarbons were measured in fish, as well as the concentration of some chlorinated hydro...
