Little is known about the variability of blood glutathione (GSH) in human subjects. Thus, we wanted to develop and validate a rapid method for measuring GSH concentrations in whole blood and apply this method to ascertain the variation of GSH in a large-scale study of free-living adults. The assay was highly sensitive (detection limit < 5 pmol) and precise, with an interassay variation of 2.3% ...

Key varietal characteristics of Sauvignon Blanc, including the descriptors ‘green’ and ‘tropical fruit’, are mostly attributed to methoxypyrazines volatile thiols, while monoterpenes, higher alcohols, esters, fatty acids, other compounds also add complexity fruity notes wines. During winemaking ageing period, oxidation decreases concentrations these diminishes flavours derived from this aromati...

The objective of this study was to evaluate the concentrations total (T-GSH), oxidised (GSSG) and reduced (GSH) glutathione in blood dairy cows, assess relationships phase number lactation, milk production, body condition score (BCS) selected biochemical parameters on its concentrations. We analysed 79 samples whole from Holstein cows. concentration assessed by spectrophotometric enzymatic meth...

Preeclampsia is pregnancy-specific, affecting 2% to 7% of women, and is a leading cause of perinatal and maternal morbidity and mortality. Preeclampsia may also predispose the fetus to increased risks of adult cardiovascular disease. Selenium, acting through the selenoprotein glutathione peroxidases, has critical roles in regulating antioxidant status. Recent reports implicate poor maternal sel...

The relation between loss of glutathione due to metal-induced phytochelatin synthesis and oxidative stress was studied in the roots of copper-sensitive and tolerant Silene cucubalus (L.) Wib., resistant to 1 and 40 micromolar Cu, respectively. The amount of nonprotein sulfhydryl compounds other than glutathione was taken as a measure of phytochelatins. At a supply of 20 micromolar Cu, which is ...

In this experiment, we compared the in vivo effects of phenylhydrazine (PHZ) and bleeding treatment on the redox status and glutathione antioxidative mechanism parameters in the plasma and red blood cells (RBC) of rats. Results showed a lower level of reactive oxygen species (ROS), a higher level of lipid peroxidation and the effective antioxidative role of the glutathione system in the blood o...
