This experiment was carried out to evaluate the effects of feeding green tea powder on laying performance and egg quality in hens. A total 180 “Tetran Brown” laying hens aged 40 weeks were assigned to 6 treatments in a completely randomized design. Each treatment consisted of five replicates accommodating six layers per replication. The experimental diets were a negative control containing no g...

Background: Visfatin is protein with insulin-like function that is expressed in high levels in visceral fat tissue and its circulating levels is associated with obesity and diabetes. Objective: The purpose of this study was to examine the effect of 10 weeks of rhythmic aerobic exercise and green tea supplementation on visfatin levels and insulin resistance in obese type II diabetic women. Met...

The aim of this study was to evaluate the effects of green tea Camellia sinensis extract on proinflammatory molecules and lipolytic protein levels in adipose tissue of diet-induced obese mice. Animals were randomized into four groups: CW (chow diet and water); CG (chow diet and water + green tea extract); HW (high-fat diet and water); HG (high-fat diet and water + green tea extract). The mice w...

AIM We examined whether green tea supplementation for 12 weeks induces changes in composition of the human gut microbiota. METHODS 58 Caucasian men and women were included in a randomized, placebo-controlled design. For 12 weeks, subjects consumed either green tea (>0.56 g/...

Green tea catechins inhibit the function of organic anion transporting polypeptides (OATPs) that mediate the uptake of a diverse group of drugs and endogenous compounds into cells. The present study was aimed at investigating the effect of green tea and its most abundant catechin epigallocatechin gallate (EGCG) on the transport activity of several drug transporters expressed in enterocytes, hep...
