... and inhibition of protein denaturation technique, respectively. The anti-nociceptive activity of AFMV was investigated in Swiss Albino mice by acetic acid-induced writhing test and formalin-induced paw licking test. The antioxidant activities of AFMV, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical...

... treatment decreased oxidative stress (LPO, NO), down-regulation gene expression levels ( TNF-α, IL-1β , and BAX ), and this antileishmanial activity of nanoparticles was associated with enhanced antioxidant enzyme activities. In addition, histopathological evaluation proved the antileishmanial activity...

... to investigate the effects of Rosmarinus officinalis L. (rosemary) extract against HSV-1 and HSV-2 in vitro . The antioxidant activity of this extract was investigated by superoxide anion and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical assays. Rosemary extract was evaluated by an HSV-1 antiviral assay...

... during the freezing and thawing process. Among such insults, the generation of supra-physiological levels of reactive oxygen species (ROS) could impair cellular functions and survival. Antioxidants are potential additives that were reported to partially or completely reverse freeze-thaw stress-associated...

... (ROS) generation and Nox1 protein expression induced by H 2 O 2 . Moreover, the decreased antioxidant enzymes activities of superoxide dismutase (SOD), catalase (CAT), and glutathione-peroxidase (GSH-PX) and elevated (MDA) level in H 2 O 2 -treated cells were reversed to the normal standard...

... damages elicited by Cd and uphold the intercellular antioxidant status in testes. Histological changes were studied and the immunohistochemical staining for caspase 3, HSP70, and eNOS protein expressions were also analyzed to justify the protective action of GSP. Furthermore, GSP prevented DNA damage...

.... For this reason, the use of natural bioactive compounds with antioxidant activity could be a strategic tool to overcome ultraviolet A (UV-A) induced deleterious effect. Neferine is an alkaloid extract from the seed embryos of lotus ( Nelumbo nucifera Gaertn). In the present study, we report the protective effect...

... mitigated by pharmacological inhibition of oxidative stress using an antioxidant, N-acetylcysteine. Taken together, these results reveal an important correlation between Ftmt and oxidative stress after TBI. Ftmt deficiency aggravates TBI-induced brain injuries and neurological deficits, which at least...

ASA also showed antioxidant activity in both cell lines. The bcl-2 , p53 and cox-2 genes in both cell lines treated with ASA seem to exhibit...

.... Similar effects were observed in mouse islets with respect to elevation of p47 phox and iNOS levels. Addition of antioxidants SOD (superoxide dismutase), Cat (catalase) and NAC ( N -acetylcysteine) attenuated H 2 O 2 or the saturated fatty acid palmitate-dependent effects, but not cytokine-induced...

Notably, independent of ROS status, polyphenol CUR prevented hyphae development in both liquid and solid hypha-inducing media by targeting the global suppressor TUP1 (thymidine uptake 1). Taken together, our results provide...
