NADP-Dependent Isocitrate Dehydrogenase from Arabidopsis Roots Contributes in the Mechanism of Defence against the Nitro-Oxidative Stress Induced by Salinity

The Scientific World Journal, 2012
NADPH regeneration appears to be essential in the mechanism of plant defence against oxidative stress. Plants contain several NADPH-generating dehydrogenases including isocitrate dehydrogenase (NADP-ICDH), glucose-6-phosphate dehydrogenase (G6PDH), 6 ...

Molecular Mechanisms of Coffee on Prostate Cancer Prevention

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Prostate cancer (PCa) is one of the most common types of cancer among men, and coffee is associated with a reduced risk of developing PCa. Therefore, we aim to review possible coffee molecular mechanisms that contribute to PCa prevention. Coffee has an important antioxidant capacity that reduces oxidative stress, leading to a reduced mutation in cells.

Substâncias antioxidantes cosméticas

Revista Científica da FHO|Uniararas, 2018
O envelhecimento é causado por alterações fisiológicas e bioquímicas que ocorrem naturalmente ao longo da vida, sendo a pele o órgão que se observa, nitidamente, esse processo. O envelhecimento cutâneo é distinguido em intrínseco e extrínseco. Um dos seus principais aceleradores são os radicais livres, que são moléculas instáveis, reativas capazes de ...
