Higher aluminum (Al) content in infant formula and its effects on neonatal brain development are a cause for concern. This study aimed to evaluate the distribution and concentration of Al in neonatal rat brain following Al treatment, and oxidative stress in brain tissues induced by Al overload. Postnatal day 3 (PND 3) rat pups (n =46) received(More)
The dominant lethal assay was utilized to assess the reproductive performance in male mice, possible genetic hazards, and persistent damage of aluminum (Al). Al chloride, AlCl(3), was administered subcutaneously to CD-1 adult male mice at dosages of 0, 7, or 13mg Al/kg body weight/day for 2 weeks of pre-mating periods. Females were not dosed at any time(More)
End stage renal disease patients undergoing long-term dialysis are at risk for abnormal concentrations of certain essential and non-essential trace metals and high oxidative stress. We evaluated the effects of zinc (Zn) supplementation on plasma aluminum (Al) and selenium (Se) concentrations and oxidative stress in chronic dialysis patients. Zn-deficient(More)
AIM To assess the extent of micronutrient and oxidative stress in blood and to examine their linkages with viral loads in chronic hepatitis C patients. METHODS Hepatitis C virus (HCV)-RNA levels were quantified in the serum from 37 previously untreated patients with chronic hepatitis C. The plasma and erythrocyte micronutrients (zinc, selenium, copper,(More)
High aluminum (Al) content in certain infant formula raises the concern of possible Al toxicity on brain development of neonates during their vulnerable period of growing. Results of in vivo study showed that Al content of brain tissues reached to 74 μM when oral intake up to 1110 μM, 10 times of that in the hi-Al infant formula. Utilizing a cultured neuron(More)
Polyamines are involved in cellular growth, differentiation and regulation of oxidative stress. The present investigation was to determine the effect of aluminum (Al) toxicity on the nitric oxide products (NO(x)) and metabolism of polyamines in mouse testes and epididymis. Aluminum chloride, AlCl(3,) was administered intraperitoneally to CD-1 adult male(More)
The present study was conducted to compare the trace elements and oxidative status between uremic patients with and without dementia. Chronic hemodialysis patients with dementia (n = 20) and without dementia (n = 25), and age-matched healthy volunteers (n = 20) were enrolled. The nutritional status, blood levels of trace elements aluminum (Al), zinc (Zn),(More)
Present work was carried out to investigate how testicular selenium (Se) metabolisms respond to oxidative stress induced by aluminum (Al). Mice were intraperitoneally exposed to 0, 7, or 35mg Al/kg/d for 14 days (CNL, LAL and HAL groups). Al administration significantly increased Al, reactive oxygen radical and malondialdehyde (MDA) levels, as well as(More)
The present investigation was conducted to assess the effects of subacute aluminum (Al) exposure on testicular zinc (Zn), copper (Cu), and iron (Fe) distribution in mice. Animals were intraperitoneally exposed to 0, 13, or 35 mg Al/kg body weight/d for a period of 14 d. Al concentrations in serum and testis in Al-treated animals were significantly higher(More)
OBJECTIVES To evaluate the effects of zinc supplementation on serum zinc and copper levels, and the severity of adverse reactions and virologic responses in chronic hepatitis C patients undergoing interferon (IFN)/ribavirin therapy. DESIGN AND METHODS Forty subjects were randomly assigned to receive IFN-alpha-2a/ribavirin with or without zinc gluconate(More)
