The purpose of this study was to compare the antioxidant ability of royal jelly, vitamin E and vitamin C as additives to the maturation media on in vitro maturation of goat oocyte. To prepare goat oocytes, ovaries collected from local slaughterhouse were transported to the laboratory into the flask containing warm saline (30-34oC( in less than an hour. Cumulus oocyte complexs were removed from ...
the objective of this study was to investigate the propensity of permethrin (ptn) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin c. forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgl-1 permethrin and 0 mgl-1 vitamin c), ptn-0.16 (0....
introduction: lead (pb) is a neurotoxin that its different effects on the central nervous system are well-known. previous studies have reported the potent effects of vitamin c on memory.the present study was undertaken to evaluate the protective effects of vitamin c against leadinduced amnesia. methods: male wistar rats were divided into 4 groups: the control (saline), negative control (lead), ...
this study was undertaken to assess vitamin c status in allergic children. twenty-six allergic patients and 46 apparently healthy controls aged 7-16 years of both sexes were introduced. all patients were diagnosed being allergic based on their histories, physical examinations and laboratory findings. blood samples were obtained between 09.00-11.00 to determine total serum immunoglobulin e, hist...
background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...
Background: Oxidative modification of low-density lipoprotein (LDL) appears to be an early step in the pathogenesis of atherosclerosis. Meanwhile, myeloperoxidase (MPO)-catalyzed reaction is one of the potent pathway for LDL oxidation in vivo. The aim of this study was to evaluate in vitro antioxidant effects of vitamins C and E on LDL oxidation mediated by MPO. Methods: MPO was isolated from f...

background: paraquat is nonselective bipyridyl herbicide that induces hepatotoxicity through oxidative stress. vitamin c and chitosan have antioxidant as well as radical scavenger properties and show protective effects against reactive oxygen species (ros). in the present study, hepatoprotective effects of chitosan and vitamin c were evaluated in common carp exposed to paraquat. methods: while ...
Density functional theory calculations were performed to investigate vitamin C interaction withN-doped TiO2 anatase nanoparticles. The adsorption of vitamin C on the energy favorable fivefoldcoordinated titanium sites was investigated. Various adsorption geometries of vitamin C towardsthe nanoparticle were examined. Since the adsorption energies of N-doped nanoparticles are higherthan those of ...
