The scale-less carp (Gymnocypris przewalskii) inhabits Lake Qinghai located on the Qinghai-Tibet plateau (elevation, 3200 m) in western China. The lake waters are alkaline (pH 9.4, titratable alkalinity=30 mmol l(-1)), Mg(2+)-rich (18.7 mmol l(-1)), Ca(2+)-poor (0.30 mmol l(-1)) and saline (9 per thousand ). These fish make annual spawning migrations into freshwater rivers. We investigated the ...

This study aimed to identify histamine-forming bacteria (HFB) and the sources of introduction such recommend control measures mitigate histamine formation in yellowfin tuna (YFT). Field samples were collected from multi-day boats that landed at Dikkowita, Negombo, Trincomalee Dondra fishery harbours. Ice fish holds (n=63) chill transport vehicles (n=63), swabs boat decks skin YFT collected. Fis...

The intestinal changes brought about by rejection of Trichinella spiralis from mice were studied in relation to their effects on a concurrent infection with Hymenolepis microstoma, a cestode not normally rejected from mice. The rejection phase of T. spiralis was associated with a marked stunting of growth of H. microstoma given just before, during, or just after rejection of the nematode. The s...

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...

The role of cholesterol in the thermal adaptation of biological membranes is explored. Physical and chemical responses of membranes to acclimation temperature were evaluated using plasma membrane domains (basolateral and brush border) prepared from intestinal epithelia of 5- and 20 °C-acclimated rainbow trout (Oncorhynchus mykiss). Basolateral membranes (BLMs) exhibit perfect homeoviscous e...

Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...

liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...
