Dietary oxidative stress and antioxidant defense with an emphasis on plant extract administration
(2012)
Eukaryotic cells generally function in a reduced state, but an amount of reactive species is essential for several biochemical processes. The antioxidant network is the defensive mechanism that occurs when the concentration ...
Polyphenolic composition of grape stem extracts affects antioxidant activity in endothelial and muscle cells
(2015)
The aim of the present study was the assessment of the antioxidant effects of polyphenolic extracts derived from the stems of three Greek grape varieties (Moshomayro, Mavrotragano and Mandilaria) in endothelial (EA.hy926) ...
Pomegranate juice consumption increases GSH levels and reduces lipid and protein oxidation in human blood
(2014)
The aim of the present study was the assessment of the antioxidant effects of pomegranate juice (PJ) consumption in humans. Thus, 14 healthy volunteers consumed PJ daily for a period of 15 days and the changes of oxidative ...
Anticarcinogenic activity of polyphenolic extracts from grape stems against breast, colon, renal and thyroid cancer cells
(2014)
A major part of the wineries' wastes is composed of grape stems which are discarded mainly in open fields and cause environmental problems due mainly to their high polyphenolic content. The grape stem extracts' use as a ...
Assessment of polyphenolic content, antioxidant activity, protection against ROS-induced DNA damage and anticancer activity of Vitis vinifera stem extracts
(2013)
Grape extracts and wine have been studied widely due to their beneficial effects on human health. However, there are only few studies from grape stems extracts. Therefore, the main objective of the present study was the ...
Grape pomace extract exerts antioxidant effects through an increase in GCS levels and GST activity in muscle and endothelial cells
(2015)
In a previous study, we demonstrated that a grape pomace extract (GPE) exerted antioxidant activity in endothelial (EA. hy926) and muscle (C2C12) cells through an increase in glutathione (GSH) levels. In the present study, ...
Effects of polyphenolic grape extract on the oxidative status of muscle and endothelial cells
(2014)
A grape pomace extract enhanced antioxidant mechanisms in muscle and endothelial cells both in the absence and in the presence of oxidative stress-induced agent tert-butyl hydroperoxide (tBHP). In particular, muscle (C2C12) ...
Effect of a special carbohydrate-protein cake on oxidative stress markers after exhaustive cycling in humans
(2012)
Exercise has been associated with oxidative stress that is correlated with muscle fatigue and reduced exercise performance. The aim of this study was to examine the effects of a special cake (consisting of carbohydrate to ...
