چکیده بیمار های قلبی عروقی شایع ترین علت مرگ و میر در سراسر جهان و به خصوص در ایران می-باشند. هرچند در سکته های قلبی نشان داده شده است که سلول های قلبی توان تقسیم میتوزی را دارند ولی این توان محدود می باشد و در بسیاری از موارد سکته های قلبی، تمام سلول های از بین رفته ترمیم نمی شوند. بنابراین وجود یک منبع سهل الوصول از سلول ها برای سلول درمانی ضروری می باشد. در این پروژه سلول های بنیادی القایی ...
Introduction: The concentration and action of ascorbic acid in the central nervous system as a vitamin and also a neuromodulator have exercise-induced fluctuations. The present study was conducted to evaluate the effects of anaerobic exercise alone and associated with the consumption of ascorbic acid as a non pharmacological treatment for reducing seizures and increasing seizure thresholds. ...
background: oxidative stress in teratozoospermic semen samples caused poor assisted reproductive techniques (art) outcomes. among antioxidants, ascorbic acid is a naturally occurring free radical scavenger and as such its presence assists various other mechanisms in decreasing numerous disruptive free radical processes. objective: the main goal of this study was to evaluate potential protective...
in this study, a new reaction system for quantitative determination of ascorbic acid was introduced. the developed method is based on inhibitory effect of ascorbic acid on the orange g-bromate system. the change in absorbance was followed spectrophotometrically at 478 nm. the dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...
abstractbackground and purpose nowadays, the application of antioxidants and plant growth regulators has discussed for decreasing the negative effect of different stresses. ascorbic acid and sodium nitroprusside have substance caused witch the resistance to biotic and abiotic stresses. to evaluate the effect of ascorbic acid and sodium nitroprusside foliar application on some traits of safflowe...

osteoporosis is a silent epidemy of today's world, and is also a prevalent problem of health in iran. the role of nutrients such as ascorbic acid, a key antioxidant vitamin, in this disease has recently attracted researchers' attention. in this study, we studied the relation between plasma ascorbic acid concentration and bone mineral density (bmd) in women referring to jami clinic, te...
A carbon Paste electrode modified with cobalt (II) phthalocyanine (CoPC) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. The potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 M (?1- 1800 µg ML ) with a Nernstian slope of 56 mV at pH 7. The limit of detection was 0.2 µg ...
ABSTRACT A study was carried out on levels of ascorbic acid changes in patients with type II diabetes mellitus. The purpose of this study was to determine total plasma and mononuclear leukocytes ascorbic acid levels in diabetic patients blood in different age groups and four groups with respect to glucose and comparison with those of normal individuals. The subjects include 62 patients with ty...
In order to evaluate the effect of potassium sulfate fertilizer and ascorbic acid application on yield and yield components and growth of quinoa (Chenopodium quinoa Willd.), a field experiment was carried out at 2018-2019 at Isfahan, central Iran. A factorial experiment based on a randomized complete block design with three replications was used. Experimental treatments were potassium sulfate i...
