Zinc is an element that under physiological conditions preferentially binds to and is a potent inducer of metallothionein under physiological conditions. The present study was conducted to explore whether zinc supplementation morphologically and biochemically protects against diabetic nephropathy through modulation of kidney metallothionein induction and(More)
Recent studies have reported oxidative damage due to bisphosphonate (BP) in various cancer tissues and neurons, although basic fibroblast growth factor (bFGF) induced antioxidant effects in the cells. The bFGF may modulate the BP-induced oxidative stress in oral epithelium of rats. This study was undertaken to explore possible beneficial antioxidant effects(More)
Copper is an integral part of many important enzymes involved in a number of vital biological processes. Even though it is essential to life, at elevated tissue concentrations, copper can become toxic to cells. Recent studies have reported oxidative damage due to copper in various tissues. Considering the vulnerability of the brain to oxidative stress, this(More)
The present study was designed to determine the effects of both Wi-Fi (2.45 GHz)- and mobile phone (900 and 1800 MHz)-induced electromagnetic radiation (EMR) on oxidative stress and trace element levels in the kidney and testis of growing rats from pregnancy to 6 weeks of age. Thirty-two rats and their 96 newborn offspring were equally divided into four(More)
Several mechanisms for the pathogenesis of diabetic complications have been proposed, one of which is abnormal zinc (Zn) homeostasis. Zn is necessary for proper liver function since it has important antioxidant, anti-inflammatory, and antiapoptotic properties. We aimed to investigate whether or not Zn has morphologically protective effect on(More)
OBJECTIVE The aim of this study is to compare the blood lead levels in employed and unemployed women and associate the difference with sociodemographic and reproductive factors. PARTICIPANTS Out of a 100 women attending the routine check-up unit of Family Medicine Department for screening of osteoporosis and blood lead levels, 63 post-menopausal(More)
Copper plays an important role in the structure and function of metalloproteins and in the absorption of iron. The present study deals with the effects of excessive copper intake on hematological and hemorheological parameters. Drinking water containing 250 µg/mL copper for a period of 9 wk, Wistar albino rats showed increased erythrocyte count, blood(More)
