Corophium volutator (Pallas) has been recommended by the paris Commission as one of the standard species for testing chemical used in offshore oil and gas exploration/production. In the present study, gut contents of Corophium volutator have been analysed by electron probe microanalysis (EPMA) for BaSO4 and other heavy metal impurities after exposure tto spiked sediments followin...

the aim of the present work was to purify cysteine protease inhibitors from rapeseed (brassica napus l.), with potential activity on digestive protease of colorado potato beetle (cpb), leptinotarsa decemlineata (say). ammonium sulfate precipitated proteinaceous fractions; 30, 50, 70, and 100% showed 39.07, 57.03, 51.47, and 22.44% inhibition on the fourth instar larval gut general protease acti...

Homogenates of gut and mesenteric lymph node tissue from patients with Crohn's disease, ulcerative colitis, and control patients were tested for cytopathic effect (CPE) production in a series of cell lines including rabbit ileal and W138 cells. A CPE was produced in W138 cells by tissue homogenates from patients with Crohn's disease, ulcerative colitis, and control patients. Evidence was obtain...

Steroid sulfatase (STS) activity was studied in the Long-Evans rat testis. The rate of dehydroepiandrosterone sulfate (DHA-S) hydrolysis determined in whole testis homogenates was low compared to that of the corresponding microsomal fractions, which was, in contrast, as high as that expressed in homogenates from purified Leydig cells. Such an increment in STS activity between total homogenates ...

The gut microbiota plays important roles in proper gut function and can contribute to or help prevent disease. Whole grains, including oats, constitute important sources of nutrients for the gut microbiota and contribute to a healthy gut microbiome. In particular, whole grains provide NSP and resistant starch, unsaturated TAG and complex lipids, and phenolics. The composition of these constitue...

The calcium-dependent, energy-independent incorporations of 14C-labeled bases, choline, ethanolamine, and serine, into their corresponding membrane phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine, were compared in microsomes and in subcellular fractions prepared from a lysed crude mitochondrial (P2) pellet of whole rat brain. When activities were measured in...

The gut microbiota is important in the pathogenesis of energy-metabolism related diseases. We focused on the interaction between intestinal bacteria and orally administered chemical drugs. Oral administration of berberine (BBR) effectively treats patients with metabolic disorders. However, because BBR exhibits poor solubility, its absorption mechanism remains unknown. Here, we show that the gut...

1. The increase in brain gamma-aminobutyrate, glutamate and aspartate and the decrease in brain glutamine that occur when ethanol is administered to rats in vivo could be reproduced by incubating brain homogenates from rats pretreated with ethanol. 2. For the demonstration of the effects of pretreatment with ethanol on the metabolism of gamma-aminobutyrate and glutamine, the whole homogenate co...

Comparative time-course studies of glycogen synthesis from glucose 6-phosphate, glucose 1-phosphate and UDP-glucose show that glucose 1-phosphate forms glycogen at an initial rate faster than that obtained with glucose 6-phosphate and UDP-glucose. After 5min. the rates from glucose monophosphates are considerably slower. 2,4-Dinitrophenol decreases glycogen synthesis from both glucose monophosp...
