Thirty-two lambs were distributed in eight treatments under 2×2×2 factorial experiment to compare the effects of two levels of selenium (0.2 to 5 mg/kg dry matter [DM]), sulphur (0.25% and 0.37%) and copper (8 and 25 mg/kg DM) levels on selenium concentration in liver and serum of lambs. A liver biopsy was done on all animals and blood samples were collected from the jugular vein prior to the b...

This study was conducted to determine the serum and milk levels of thiobarbturic acid-reac- tive substances (TBARS), nitric oxide (NO), superoxide dismutase (SOD), glutathione peroxi- dase (GSH-Px), vitamin E selenium, IL-4 IL-6 in lactating dairy cows affected with bloody using commercially available ELISA kits. Milk whole blood samples were collected from 60 20 apparently healthy for control....

The experiment was conducted to study productive, physiological and immunological parameters in Bandarah local chicks as affected by dietary organic selenium (SelPlexTM). All chicks were used in the present work produced from females and males fed diets with 0.0, 0.1, 0.2 and 0.3 mg Se / kg diet in the form of selenium yeast (Sel-PlexTM). Two hundred unsexed oneday old chicks (50 chicks per par...

BACKGROUND Copper and selenium are important trace elements in man. They function as antioxidants and play roles in oxido-reductase reactions. Several imported multivitamin preparations are given to our women during pregnancy and lactation to correct possible deficiencies. OBJECTIVE The aim of the study is to determine the serum level of these micronutrients (selenium and copper) in a cross s...

BACKGROUND Human immunodeficiency virus infected individuals are prone to malnutrition due to increased energy requirements, enteropathy and increased catabolism. Trace elements such as zinc and selenium have major role in maintaining a healthy immune system. This study was designed to evaluate the nutritional status of Iranian subjects who were newly diagnosed with human immunodeficiency virus...

OBJECTIVE To determine whether serum selenium levels are associated with the conversion of bacteriological tests in patients diagnosed with active pulmonary tuberculosis after eight weeks of standard treatment. METHODS We evaluated 35 healthy male controls and 35 male patients with pulmonary tuberculosis, the latter being evaluated at baseline, as well as at 30 and 60 days of antituberculosis...

The essential micronutrient, selenium, is at low levels in the New Zealand diet. Selenium is a component of a number of proteins involved in the maintenance of genomic stability, and recommended daily allowances (RDA) are set on saturation levels for glutathione peroxidase (GPx), a key enzyme in surveillance against oxidative stress. It has been assumed but not proven that this level will be ad...

Vitamin D deficiency is a global health threat that has been associated with several chronic diseases. Selenium is an essential trace element because of role in major metabolic processes, immune function, thyroid hormone metabolism, male infertility, neoplasms and cardiovascular disease. We aimed to investigate for the first time in the Saudi population the association between vitamin D and sel...

The Czech Republic ranks among the countries with the highest prevalence of dyslipoproteinemia and cardiovascular diseases (CVD). As a valid tool in their primary prevention, the authors consider monitoring of selected components (including metal ions and vitamins) of the body's antioxidant system.The study was focused on monitoring the health condition of members of the Czech Republic Rescue F...

BACKGROUND From March 1986 through May 1991, we conducted a randomized nutritional intervention trial, the General Population Trial, in Linxian, China, a region with epidemic rates of squamous esophageal and adenomatous gastric cardia cancers. We found that participants who received selenium, beta-carotene, and vitamin E had significantly lower cancer mortality rates than those who did not. In ...
