BACKGROUND: Obstetricians usually prescribe supplements during pregnancy without actual indication. The use of selenium during pregnancy has increased, due to its function in several antioxidant mechanisms. CASE: A pregnant woman received 200,000 micrograms (μg) per day of a selenium galenic formulation, since gestational week (g.w.) 7 to 12, due to a prescription error. The patient experienced nausea, vomiting, hand and foot paresthesia, followed by fatigue, loss of fingernails and hair...

Extremely preterm infants are at high risk for morbidities including bronchopulmonary dysplasia, intraventricular hemorrhage, and retinopathy of prematurity likely related to their exposure to reactive oxygen and nitrogen species early in life. Selenium is a trace mineral contributes to the proper function of multiple systems including immunity, redox regulation, and inflammation via the "selenoenzymes" glutathione peroxidase, thioredoxin reductase, and selenoprotein P. Given that selenium accretion via the placenta occurs primarily during the third trimester, preterm neonates are born selenium deficient...

Exploring the migration behaviors of selenium in granite is critical for the safe disposal of radioactive waste. The matrix diffusion and sorption of 75Se(IV) (analogue for 79Se) in granite were systematically studied to set reliable parameters in this work. Through-diffusion and batch sorption experiments were conduct with four types of Beishan granite. The magnitudes of the obtained apparent diffusion coefficient (Da) values are of the following order: monzogranite > granodiorite-2 > granodiorite-1, which is opposite to the sequence of the Kd values obtained from both the diffusion model and batch sorption experiments...

During the last couple of decades, the rapidly advancing field of nanotechnology has produced a wide palette of nanomaterials, most of which are considered as "synthetic" and, among the wider public, are often met with a certain suspicion. Despite the technological sophistication behind many of these materials, "nano" does not always equate with "artificial". Indeed, nature itself is an excellent nanotechnologist. It provides us with a range of fine particles, from inorganic ash, soot, sulfur and mineral particles found in the air or in wells, to sulfur and selenium nanoparticles produced by many bacteria and yeasts...

Patients with inflammatory bowel disease (IBD) are at high risk for nutritional deficiencies because of long-term inflammation in the gut mucosa and decreased oral intake. Because inflammation responses affect serum micronutrient concentrations, serum levels are limited in reflecting body nutrient status in acute and chronic illness. We investigated the usefulness of measuring trace elements in hair as reliable markers of nutritional status compared to serum levels in children with IBD. We retrospectively analyzed pediatric patients newly diagnosed with Crohn's disease (n = 49) and ulcerative colitis (n = 16) and controls (n = 29) from 2012 to 2016...

Minerals play a major role in regulating cardiovascular function. Imbalances in electrolyte minerals are frequent and potentially hazardous occurrences that may lead to the development of cardiovascular diseases (CVDs). Transition metals, such as iron, zinc, copper and selenium, play a major role in cell metabolism. However, there is controversy over the effects of dietary and supplemental intake of these metals on cardiovascular risk factors and events. Since their pro-oxidant or antioxidant functions can have different effects on cardiovascular health...
