Green tea influences intestinal assimilation of lipids in humans: a pilot study
OBJECTIVE: Many data show that green tea (GT) consumption has a beneficial effect on human health, including antiinflammatory,
antibacterial and anticarcinogenic activities. However, there are no data on the effect of long-term GT intake on lipid assimilation
not related to luminal processes. Therefore, in the present study, we aimed to assess the impact of a three-month diet enriched in green tea
extr...

Green tea extract and its major constituent epigallocatechin-3-gallate inhibit growth and halitosis-related properties of Solobacterium moorei
that has been associated with halitosis. The aim of this study was to investigate the effects of green tea extract and its
major constituent epigallocatechin-3-gallate (EGCG) on growth and several halitosis-related properties of S. moorei.
Methods: A microplate dilution assay was used to determine the antibacterial activity of green tea extract and ...

Epigallocatechin-3-gallate (EGCG) Suppresses the Trafficking of
Lymphocytes to Epidermal Melanocytes via Inhibition of JAK2:
Its Implication for Vitiligo Treatment
Vitiligo is an inflammatory skin disorder in which activated T cells play an important role in its onset and progression. Epigallocatechin-3-gallate (EGCG), the major chemical constituent of green tea, exhibits remarkable anti-oxidative and anti-inflammatory properties. EGCG administration has been confirmed to decrease the ...

Effect of green tea extract on bonding durability of an etch-and-rinse adhesive system to cariesaffected dentin
Objective: Green tea extract has been advocated as a matrix metalloproteinase (MMP) inhibitor; however, its effect on bond durability to caries-affected dentin has never been reported. Thus, the aim of this in vitro study was to evaluate the effect of two MMP inhibitors (2% chlorhexidine and 2% green tea extract), applied after acid etching, on bond durability of an etch-and-ri...

Dissipation Pattern, Processing Factors, and Safety Evaluation for Dimethoate and Its Metabolite (Omethoate) in Tea (Camellia
Sinensis)
Residue levels of dimethoate and its oxon metabolite (omethoate) during tea planting, manufacturing, and brewing were investigated using a modified QuEChERS sample preparation and gas chromatography. Dissipation of dimethoate and its metabolite in tea plantation followed the first-order kinetic with a half-life of 1.08–1.27 d. Tea manufacturing ...

Comparative effects of selected plant polyphenols, gallic acid
and epigallocatechin gallate, on matrix metalloproteinases
activity in multidrug resistant MCF7/DOX breast cancer cells
The aim of the study was to investigate the effect of selected polyphenols: gallic acid (GA) and epigallocatechin gallate (EGCG) on matrix metalloproteinase (MMP-2 and MMP-9) activity in multidrug resistant (MDR) human breast adenocarcinoma cells: MCF7/DOX cells and
obtained recently in our laboratory ...
