We investigated the effects of dietary supplementation of zinc (Zn) with or without vitamin A (Vit. A), to elucidate any cross activity between the two micronutrients, on memory and nerve growth factor (NGF) production in ddY male mice depleted for the two elements. After 3 mo-feeding with a Zn and Vit. A deficient (VAD) diet, mice were divided into three groups and replenished with normal Zn w...

Background: Low vitamin D (vit D) serum levels have been linked to various diseases such as multiple sclerosis, cardiovascular diseases, and diabetes. Maintenance of optimal vit D level should be supported by foods and supplements. Limited food sources of vit D made researchers focus on food fortification in recent years. Methods: A systematic review of randomized controlled trials reporting th...

Background: The placental calcification is often considered as a physiologic aging process of the placenta but it may be accompanied with the altered levels of vitamin D (vit D). The aim of this study was to evaluate association between placental calcification and vit D in low risk pregnant women.  Materials and Methods: In a case-contro...

The extrinsic sources for erosion-causing acids are primarily acidic beverages and foodstuffs. Effervescent tablets also contain organic acids (e.g. citric, tartaric, malic) in order to form carbon dioxide by contact with water – with the help of the carbonate salts of the tablets. To adequately inform patients about the possible erosive potential of effervescent tablets, this study was underta...

BACKGROUND Low serum vitamin (vit) D levels are common even in sunny countries. We assessed the prevalence and relationship of low vit D with cardiovascular risk factors in Qatar. METHODS Data were collected retrospectively from January 2008 and November 2009. In patients who had low vi t D (< 30 ng/ml ) , demographic and clinical profiles were analyzed and compared in males and females. RE...

OBJECTIVE To compare the levels of plasma homocysteine (Hcy), vitamin B6 (vit-B6), serum vitamin B12 (vit-B12), and folate in healthy individuals and in patients with normal tension glaucoma (NTG), pseudoexfoliative glaucoma (PXG), or primary open-angle glaucoma (POAG). STUDY DESIGN A prospective controlled trial. PARTICIPANTS AND METHODS Forty healthy subjects, 48 patients with NTG, 38 pat...

background and objective: vitamin d (vit d) has an important role as immunoregulator. its deficiency is deemed as a risk factor for respiratory system infection. in this study the serum vit d levels of healthy and with pneumonia children were compared. methods: in this prospective case control study, 31 hospitalized children due to pneumonia and 40 healthy children both aged between 6 and 60 mo...

the objective of this study was to investigate the propensity of permethrin (ptn) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin c. forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgl-1 permethrin and 0 mgl-1 vitamin c), ptn-0.16 (0....

Blood selenium and trace minerals play an important role in animal’s health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and ...
