association of serum zinc and selenium concentration in the etiology of miscarriage in iranian women
background: adequate serum level of zinc and selenium is required for normal metabolic performance and successful fertility. the present study was conducted to evaluate the association of serum zinc and selenium in early stage of gestation with the incidence of miscarriage in iranian women. materials and methods: one hundred two females were studied in three matched groups. group 1 consisted of...
Introduction: Metal ions are required for various vital body functions and metabolism. Selenium is an active element in selenoproteins and plays an important role in public health, though the increase of its concentration in the body can cause toxicity. Therefore, it seems essential to investigate the serum selenium status of individuals of a society. This study was conducted to determine serum...
background: gastric cancer (gc) is the most common gastrointestinal cancer in iran. helicobacter pylori (h. pylori) accounts as one of the main risk factors for gastric non-cardia cancer (gncc). it is suggested that high serum selenium level may have a protective role in gncc. in this cross-sectional study, we determined the serum se level and the status of h. pylori infection in two population...
the aim of the study was to assess regional differences in selenium content in the environment based on analysis of the se concentrations in liver and kidney of red deer from central, northern, south-eastern and south-western poland. the level of selenium in organs was determined using spectrofluorometric methods. the mean concentration of selenium in the liver and kidney of red deer was 0.084 ...
Background: Gastric cancer (GC) is the most common gastrointestinal cancer in Iran. Helicobacter pylori (H. pylori) accounts as one of the main risk factors for gastric non-cardia cancer (GNCC). It is suggested that high serum selenium level may have a protective role in GNCC. In this cross-sectional study, we determined the serum Se level and the status of H. pylori infection in two population...
PURPOSE It has been suggested that selenium deficiency is a risk factor for several cancer types. We conducted a case-control study in Szczecin, a region of northwestern Poland, on 95 cases of lung cancer, 113 cases of laryngeal cancer and corresponding healthy controls. METHODS We measured the serum level of selenium and established genotypes for four variants in four selenoprotein genes (GP...
Introduction: The aim of study was to compare umbilical cord blood selenium levels in respiratory distress syndrome (RDS) and non RDS preterm babies. Methods: Umbilical cord blood selenium levels of all preterm newborn born during a 6-month period were enrolled in the study. They were divided into two groups: RDS and non RDS. Selenium level was assessed by using electro-thermal atomic ab...
Background and Objective: Breast cancer is the most commonly diagnosed cancer in women worldwide, which alone accounts for 30% of all new cancer cases in women. The development of cancer is a multistep process. The complex series of cellular and molecular changes participating in cancer development are mediated by a diversity of stimuli such as Oxidative stress that is known to cause DNA damag...
Introduction Selenium is an essential element to human health at low levels (2080 μg/L), but becomes toxic at elevated levels. Selenium exists in different forms that determine its toxicity and bioavailability. Current research is now focusing on the determination of individual selenium species or seleniumcontaining compounds. This can be done using ICP-MS as a selenium-specific detector for a ...
