Endogenous and Exogenous Modulation of Nrf2 Mediated Oxidative Stress Response in Bovine Granulosa Cells: Potential Implication for Ovarian Function
Nrf2 is a redox sensitive transcription factor regulating the expression of antioxidant genes as defense mechanism against various stressors. The aim of this study is to investigate the potential role of noncoding miRNAs as endogenous and quercetin as exogenous regulators of Nrf2 pathway in bovine granulosa cells. For this cultured granulosa cells were used for modulation of miRNAs (miR-28, 153 ... إقراء المزيد

CIRCULATING VASCULAR  ENDOTHELIAL GROWTH FACTOR AND NITRIC OXIDE IN PATIENTS WITH LIVER CIRRHOSIS: A  POSSIBLE ASSOCIATION WITH LIVER FUNCTION IMPAIRMENT
Hemodynamic disorders of liver cirrhosis complicated with portal hypertension are associated with an increased angiogenesis in animal model of portal hypertension and cirrhosis which were linked to increased expression of vascular endothelial growth factor (VEGF) and nitric oxide (NO). The aim of study was to evaluate the serum concentration of VEGF and total nitric oxide (NO) in liver cirrhosis and ... إقراء المزيد

Electrochemical behaviour of antioxidants: Part 2. Electrochemical oxidation mechanism of quercetin at glassy carbon electrode modified with multi-wall carbon nanotubes
Electrochemical oxidation mechanism of quercetin was investigated at glassy carbon electrode modified with multi-wall carbon nanotubes in aqueous 0.2 M phosphate solutions with different pHs. The investigation was carried out using cyclic voltammetry, double potential step chronoamperometric and chronocoulometric techniques. It was found that the oxidation mechanism proceeds in sequential steps, related with the five-hydroxyl groups in the three aromatic ... إقراء المزيد
