Apostichopus japonicus is a common sea cucumber that undergoes seasonal inactivity phases and ceases feeding during the summer months. We used this sea cucumber species as a model in which to examine phenotypic plasticity of the digestive tract in response to food deprivation. We measured the body mass, gross gut morphology and digestive enzyme activities of A. japonicus before, during, and aft...

To explore the causes of different growth rates among juvenile populations largemouth bass, in present study, a batch bass juveniles reared under same conditions were divided into fast-growing group and slow-growing group. We used histological, enzymatic molecular biology methods to analyze determine their histomorphological changes, digestive enzyme activity intestinal floral composition. The ...

The objective of this study was to investigate the relationship between heat shock protein 70 (HSP70) overexpression and intestinal structure and digestive function in heat-stressed broilers. In total, 240 male broilers were injected intraperitoneally with l-(1)-glutamine (0.75 mg/kg of BW) or quercetin (5 mg/kg of BW). Twenty-four hours later, they were heat-stressed for 0, 2, 3, 5, and 10 h, ...

background: little in known regarding the clinical relevance of sirt1 in multiple sclerosis (ms).   here, we aimed to evaluate mrna expression, protein level and enzyme activity of sirt1 in peripheral blood mononuclear cells (pbmcs) isolated from relapsing –remitting ms patients (rrms) and healthy controls. materials and methods: twenty patients with rr-ms and twenty two age- and sex-matched he...

Plant-based animal feed contains antinutritive agents, necessitating the addition of digestive enzymes in commercial feeds. Enzyme additives are costly because they are currently produced separately from recombinant sources. The coexpression of digestive enzymes in a single recombinant cell system would thus be advantageous. A coexpression system for the extracellular production of phytase and ...

Aquaeous methanolic extracts of pomegranate peel (Punica granatum) and veratrum (Veratrum album) were evaluated for their effects supplementation in fish diets on oxidative status, digestive enzymes immunity rainbow trout fingerlings (Oncorhynchus mykiss). Three different concentrations 250 (P250), 500 (P500) 1000 (P1000) mg kg-1 (V250), (V500) (V1000) added to the diet fed these 60 days over a...

Pancreatic duct obstruction, even in the absence of biliary obstruction and/or bile reflux into the pancreatic duct, can trigger acute hemorrhagic necrotizing pancreatitis. The earliest changes are seen within acinar cells. Early derangements in acinar cell biology include inhibition of digestive enzyme secretion and the co-localization of lysosomal hydrolases with digestive enzyme zymogens. Un...
