objective(s): exposing to stress may be associated with increased production of reactive oxygen species (ros). therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. it has been presented that brain-derived neurotrophic factor (bdnf) supports neurons against various neurodegenerative conditio...
γ-l-glutamyl-S-[2-[[[3,4-dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H-1-benzopyran-6-yl]oxy]carbonyl]-3-[[2-(1H-indol-3-yl)ethyl]amino]-3-oxopropyl]-l-cysteinylglycine sodium salt (ESeroS-GS) is a water-soluble derivative of α-tocopherol (vitamin E). We reported previously that ESeroS-GS can act as an anti-inflammatory agent and can induce cell death in breast cancer cells. Howev...
Mitochondrial respiration relies on electron transport, an essential yet dangerous process in that it leads to the generation of reactive oxygen species (ROS). ROS can be neutralized within the mitochondria through enzymatic activity, yet the mechanism for steady-state removal of oxidized mitochondrial protein complexes and lipids is not well understood. We have previously characterized vesicul...
o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...
background: the present study was carried out to investigate the possible protective effects of royal jelly (rj) on oxymetholone (oxm)-induced oxidative liver injuries in mice. methods: in total, 32 adult male nmri mice were divided into four groups of eight mice each. mice in groups 1 and 2 were orally administered 5 mg/kg/day oxm for 30 days. at the same time, mice in group 3 received rj at a...
conclusions with regard to the potent antioxidant properties of silymarin, the neuroprotective effects of this natural compound suggested in the current study may in part be mediated through inhibition of oxidative stress. results exposure to acr reduced cell viability in pc12 cells. pre-treatment of cells with silymarin (100 µm) significantly reduced acr-induced toxicity. in addition, administ...
in the present study, free-radical-scavenging and antioxidant activities of angipars™, an herbal extract which has been registered as a therapeutic drug for diabetic foot ulcer, were examined. we investigated the protective effect of angipars™ on cytotoxicity produced by exposure to h2o2 (300 µm) in hepg2 and a549 cell lines, using mtt assay, glutathione (gsh) content analysis, and lipid peroxi...
propionic acid (pa) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. the present study was undertaken to investigate the effect of pa on liver injury in male rats. male western albino rats were divided into two groups. the first group served as normal control, the second was treated with pa. the activities of serum hepatospecific ...
evaluating radioprotective effect of hesperidin on acute radiation damage in the lung tissue of rats
background: oxidative stress plays an important role in the pathogenesis and progression of γ-irradiation-induced cellular damage, lung is a radiosensitive organ and its damage is a dose-limiting factor in radiotherapy. the administration of dietary antioxidants has been suggested to protect against the succeeding tissue damage. the present study aimed to evaluate the radioprotective efficacy o...
Brucellosis, caused by a facultative intracellular pathogen Brucella, is one of the most prevalent zoonosis worldwide. Host infection relies on several uncanonical virulence factors. A recent research hotpot is the links between carbon metabolism and bacterial virulence. In this study, we found that a carbon metabolism-related pyruvate kinase (Pyk) encoded by pyk gene (locus tag BAB_RS24320) wa...
