Liver function tests, thyroxin and triiodothyronine levels, and hepatic 5’deiodinase and glutathione peroxidase enzyme activities were measured. Triiodothyronine levels in the carbon tetrachloride group and carbon tetrachloride + selenium group were significantly lower than in the control group (P<0.01, P<0.05, respectively). In the carbon tetrachloride + selenium group, the level of triiodothy...
Selenium and molybdenum are essential trace elements. Considering the characteristics of selenium and molybdenum, our research had the following purposes for both elements: Considering Se the uptake of selenium was investigatein maize and sunflower seedling, moreover the different effect of two selenium species (selenite and selenite) for the examined plants (a monocotyledon (maize, Zea mays L....
Introduction: This study examined the effect of adding selenium to levothyroxine on controlling primary overt hypothyroidism and reducing the serum level of thyroid peroxidase antibody. Materials and Methods: This study was a double-blind, randomized clinical trial on individuals with primary autoimmune hypothyroidism. The patients were randomly divided into two intervention (I) and control (C...
objective: to compare the maternal and umbilical cord serum selenium concentrations in low and normal birth weight neonates. materials and methods: a case-control study was carried out in vali-asr and akbarabadi hospitals (jan. to dec. 2013). two groups; case group; 91 mothers who delivered a low birth weight (lbw) neonate and control group; 86 subjects who delivered a normal birth weight neona...
Three protocols were used to determine the effects of dietary selenium concentration on the development of gamma-glutamyl-transpeptidase (GGT)-positive foci and hepatocellular carcinoma induced by either diethylnitrosamine (DEN) or N-acetylaminofluorene in rats. In the first experiment, foci were induced by a carcinogenic dose of DEN (100 mg/kg body weight, p.o.) at 20-22 h after two-thirds par...
Background: Multiple Sclerosis (MS) is an autoimmune disease, resulting in chronic inflammatory lesion of the nerve or destruction of myelin, the white substance of the brain, spinal cord and optic nerves. This disease, like other autoimmune diseases are more common among young women in a way that most young people are affected with it. The disease affects older aged men in and is diagnosed in ...
Oxidation of ethylene to ethylene oxide over silver catalyst and selenium modified catalyst has been studied by continuous flow and pulse techniques over the temperature range of 230-280 °C. The results are discussed in terms of reaction mechanisms proposed by others, rejecting mechanisms which involve peroxide formation. It has been shown that not only selectivity towards ethylene oxide pr...
S Fallah [1] , PhD F Valinezhad Sani [2] , MSC Mohsen Firooz rai [3] , PhD Received: 2 July, 2007 Accepted: 30 Jan, 2008 Abstract Background & Aims : There are clear evidences that zinc and selenium trace elements are required for maintenance of normal metabolic and physiologic activities. Over 300 zinc methaloenzyme have been described to date. Selenium is essential in a number of importa...
Selenium deficiency is a causative factor in heart failure and microRNAs (known as miRNAs or miRs) play an important role in numerous cardiovascular diseases. However, the changes of miRNA expression during selenium deficiency and whether selenium deficiency is involved in cardiac dysfunction remain unclear. In the present study, miRNA expression profiling was carried out in normal rats, seleni...
New Zealand has one of the highest incidence rates of Crohn's Disease (CD), whilst the serum selenium status of New Zealanders is amongst the lowest in the world. A prospective case-control study in Auckland, New Zealand considered serum selenium as a potential CD risk factor. Serum selenium levels were significantly lower in CD patients compared to controls (101.8 ± 1.02 vs. 111.1 ± 1.01 ng/mL...
