Neuropsychological behavior via activation of the hypothalamic-pituitary-adrenal (HPA) axis was analyzed using young mice fed a zinc-deficient diet for 2 weeks. Serum corticosterone concentration was significantly increased after 2-week zinc deprivation, whereas zinc concentration in the brain was not decreased. In the resident-intruder test, the rate of mice that exhibited aggressive behavior ...

background: copper and zinc are the elements with numerous physiological activities.  copper  (cu)  has  an  important  role  in  angiogenesis  and  acts  by increasing vascular endothelial growth factor (vegf). serum levels of copper will be increased in cancer incidence, progression and recurrence. the aim of this study was to measure blood levels of copper, zinc, and the ratio of cu /zn, as ...

Dialysis is one of the effective methods which has been used since 1955 for the treatment of patients suffering from renal failure( more often of its chronic type). The dialysis results in the elimination of waste materials like urea and creatinine from the body, on the other hand, it can affect the serum contamination of the dialysis fluid. Aluminium is one of trace elements which its serum le...

Aims/hypothesis Low serum 25-hydroxyvitamin D [25 (OH)D] concentration may increase risk of insulinrequiring diabetes. Methods A nested case–control study was performed using serum collected during 2002–2008 from military service members. One thousand subjects subsequently developed insulin-requiring diabetes. A healthy control was individually matched to each case on blood-draw date (±2 days),...

Iron and zinc are found in similar foods and absorption of both may be affected by food compounds, thus biochemical iron and zinc status may be related. This cross-sectional study aimed to: (1) describe dietary intakes and biochemical status of iron and zinc; (2) investigate associations between dietary iron and zinc intakes; and (3) investigate associations between biochemical iron and zinc st...

Zinc deficiency is a public health concern and is the most prevalent micronutrient deficiencies in developing countries. The main objective of this study was to assess the prevalence and risk factors of zinc deficiency among infants and preschool children. Based on a community, the cross-sectional study was conducted in East Gojjam between October 2011 and April 2012. Two hundred and forty infa...

Background and Objective: It has been reported that low concentration of zinc in serum is associated with insulin resistance (IR), also appears to be a relationship between insulin and leptin. In this study the possibility of increased leptin concentration and zinc deficiency was evaluated; in the following, their relationship with overweight and IR was investigated in women with polycystic ova...

UNLABELLED In coeliac disease (CD) there is a gluten-induced small bowel enteropathy leading to malabsorption of various nutrients, vitamins and trace elements. Low levels of serum zinc have been reported in adults with untreated CD. In the present study we related the serum concentration of zinc to the morphology of the small bowel mucosa in 58 children, all under 4 years of age and under inve...

BACKGROUND Women infected with HIV face a combination of health threats that include compromised nutrition and adverse gynecological conditions. This relation among HIV, nutrition, and gynecological conditions is complex and has rarely been investigated. OBJECTIVE Our objective was to investigate nutritional biomarkers associated with several gynecological conditions among US women with or at...
