objective(s): biological applications of gold nanoparticles have limitations because of the toxic chemicals used in their synthesis. curcumin can be used as reducing as well as capping agent in synthesis of gnps to eliminate the cytotoxicity. conjugation of curcumin to gold also helps in increasing its solubility and bioavailability. materials and methods: here we report synthesis of gold nanop...

background: the aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. methods: pre-mature mice were primed with pregnant mare stimulating gonadotrophin (pmsg) and germinal vesicle (gv) stage oocytes were obtained 48 h after. the oocytes were cultured in tissue culture medium (...

objectives: iron chelators, such as maltol and kojic acid, have antioxidant and anti-inflammatory properties. they may have beneficial effects on inflammatory bowel disease (ibd) because iron can develop and aggravate inflammation in ibd. in the present study, the effect of selected iron chelators and anti-oxidants were evaluated on a model of trinitrobenzene sulfonic acid (tnbs)-induced coliti...

supplementation has beneficial effects in immune system and can antioxidant enzymes activity increases during the exercise and protects the tissue against the oxidative stress. l-carnitine is a famous supplement and helps to protect against the oxidative stress during and after intense or prolonged exercise. the aim of this study was to investigate the effect of l-carnitine supplementation on t...

INTRODUCTION Oxidative stress affects clinical outcome in critically ill patients. Although high-density lipoprotein (HDL) particles generally possess anti-oxidant capacities, deleterious properties of HDL have been described in acutely ill patients. The impact of anti-oxidant HDL capacities on clinical outcome in critically ill patients is unknown. We therefore analyzed the predictive value of...

Curcumin metabolites namely curcumin monoglucuronide and curcumin diglucuronide were synthesized using an alternative synthetic approach. The anti-oxidant potential of these curcumin glucuronides was compared with that of curcumin using DPPH scavenging method and Oxygen Radical Absorbance Capacity (ORAC) assay. The results show that curcumin monoglucuronide exhibits 10 fold less anti-oxidant ac...

conclusions therefore, our results suggest that although administration of 300 mg/kg of calendula officinalis extract showed salutary effects on anti-oxidant profile, yet its protective effects on anti-diabetic and regenerative properties on nephropathy were ambiguous and require more investigations. background chronic hyperglycemia leads to microvascular and macrovascular complications such as...

context to provide an updated review of published literature on the anti-oxidant, anti-bacterial and anti-inflammatory properties of honey. evidence acquisition cinahl, biomed central, cochrane library, medline and embase data bases and reference lists were used to find randomized controlled trials and review articles. randomized controlled trials using honey with a comparator were reviewed, al...

OBJECTIVES This study aimed to estimate the effects of 4-nonylphenol (NP), a ubiquitously present surfactant in aquatic environments, on the anti-oxidant systems of the liver in the Far Eastern catfish Silurus asotus. METHODS Changes in biochemical parameters involved in glutathione (GSH)-related and other anti-oxidant systems were analyzed following 4 weeks of 4-NP administration (0.1 and 1....
