سندروم تخمدان پلی کیستیک (polycystic ovary syndrome (pcos)) شایع ترین اندوکرینوپاتی در زنان است که 10-5% زنان در سنین باروری را مبتلا می کند و در حدود 20% از علل ناباروری زوجین را به خود اختصاص می دهد. براساس مطالعاتی که به تازگی صورت گرفته است ارتباط معناداری بین بروز استرس اکسیداتیو و pcos وجود دارد. در مواردی از آسیب های سیستم تولید مثلی مانند اندومتریوزیس و pcos دخالت سایتوکین های التهابی i...
this study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. in this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. in the first phase after the saliva collection, one group of patients took 500 mg of vitamin c powder, for 3 weeks. then, saliva of...
background and objective: oxidative stress plays an important role in the pathogensis of various diseases, including lung cancer, chronic obstructive pulmonary disease, and atherosclerosis. total antioxidant capacity plays a significant role in the body’s antioxidant defense, so its assessment is a matter of the utmost importance. currently, assessment of this capacity is performed in various s...
occurrenceofoxidative stress (os) following in vitro culture is inescapable. therefore, the aim of the present study was to determine the efficacy of coenzyme q 10 (coq 10 ) supplementation medium on developments and total antioxidant capacity (tac) of mouse vitrified pre-antral follicles. fresh and vitrified-warmed isolated preantral follicles from ovaries of 14-16 day s -old mice were cultured...
conclusions it is concluded one week oral supplementation of curcumin has positive effects on selected indices of oxidative stress possibly via promotion of antioxidant capacity. results there was a significant increase in tac after supplementation (p < 0.001, es = 1. 42), and immediately after exercise (p = 0. 008, es = 1. 12) in c group compared with the p group. mda-tbars was significantly l...
this study was conducted to assess the effect of ginger supplementation on malondialdehyde (mda) level, as an oxidative stress marker, and total antioxidant capacity (tac) in broiler chicks. two hundred male 1-day-old chicks were assigned randomly to four dietary treatments (basal diet as control group and basal diet containing 2.5, 5.0 and 7.5 g/kg ginger, respectively), with five replicates a...
conclusions our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology. patients and methods this case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. seminal plasma tac and mda were measured by ferric reducing ability of plasma (frap) and thiobarbituric acid (tb...
abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...
human milk contains all of the constituents that are required for the optimal growth and development of a neonate. it supports the development of brain, immune, and physiological systems. this study aimed to consider the significance of breast milk in preventing oxidative stress by comparing total antioxidant capacity (tac) in breast and formula milk for premature infants, demonstrating the rel...
nowadays mobile phone is very popular, causing concern about the effect it has on people's health. parotid salivary glands are in close contact to cell phone while talking with the phone and the possibility of being affected by them. limited studies have evaluated the effect of cell phone use on the secretions of these glands; so this study was designed to investigate the effects of duration of...
