Enzymatic antioxidant systems in helminth parasites

Parasitology Research, 2009
Parasitic helminths have a coexistence with mammalian hosts whereby they survive for several years in known hostile conditions of their hosts. Many explanations exist describing how these parasitic helminths are able to survive. In the last years, a lot of studies have focused on both enzymatic and non-enzymatic antioxidant systems now shown to exist ...

Antioxidant Activity of Coffee Model Systems

Journal of Agricultural and Food Chemistry, 2002
Coffee model systems prepared from combinations of chlorogenic acid (CGA), N(alpha)-acetyl-1-arginine (A), sucrose (S), and cellulose (C) were roasted at 240 degrees C for 4 min prior to analysis by UV-visible spectrophotometry, capillary zone electrophoresis (CZE), and the ABTS radical cation decolorization assay.

A manganese oxide nanozyme prevents the oxidative damage of biomolecules without affecting the endogenous antioxidant system.

Nanoscale, 2019
Biocompatible nanoparticles with an intrinsic ability to mimic the cellular antioxidant enzymes are potential candidates for the development of new therapeutics for various oxidative stress related disorders. However, the understanding of the interaction

Scuba Diving Activates Vascular Antioxidant System

International Journal of Sports Medicine, 2012
The aim was to study the effects of scuba diving immersion on plasma antioxidant defenses, nitric oxide production, endothelin-1 and vascular endothelial growth factor levels. 9 male divers performed an immersion at 50 m depth for a total time of 35 min.

Antioxidant Properties of Malt Model Systems

Journal of Agricultural and Food Chemistry, 2005
The aim of this study was to investigate the effect of kilning and roasting temperatures on antioxidant activity of malt model systems prepared from combinations of glucose, proline, and ferulic acid. Model systems (initial a(w) = 0.09, 6% moisture) were heated at 60 degrees C for up to 24 h, at 90 degrees C for up to 120 min, and at 220 degrees C for ...

Aflatoxin B1 (AFB1) induced dysregulation of intestinal microbiota and damage of antioxidant system in pacific white shrimp (Litopenaeus vannamei)

Aquaculture, 2018
Aflatoxins, especially aflatoxin B1 (AFB1), exert a substantial impact on the shrimp farming production, inducing disease with a gradual decline of reared shrimp stock quality and profitability, thus causing a significant problem in aquaculture systems ...

The integrated antioxidant system

Nutrition Research, 1995
Abstract The diversity and depth of the body's antioxidant protection system is reviewed. Components of both endogenous and exogenous origins contribute protection, and new data suggests that some components interact to spare or replace each other. Evidence from both animal and human studies shows that glutathione and vitamin C can act in concert to ...
