Serum and urinary selenium levels in obese children: A cross-sectional study

Selenium speciation in human serum and its implications for epidemiologic research: a cross-sectional study

“…We coded in the study smoking status with increasing values from one to three according to non-smoking, ex-smoking and current smoking, a choice which may have induced some exposure misclassification particularly for former smokers. Concerning the relation between BMI and Se levels, recently found to be inverse in two European studies [14,80], our estimates were too statistically unstable to allow meaningful conclusions, though the different relations we observed for single Se species are interesting and appear to deserve further investigation.…”

“…The experimental settings chosen for ICP-DRC-MS (Perkin Elmer NexIon) after optimization were: radio frequency power: 1250 W, plasma gas flow: 15 L Ar/min auxiliary gas flow: 1.05 L Ar/min, nebulizer gas flow: 0.94 L Ar/min, daily optimized, dwell time 300 ms, ions monitored: 78 Se, 80 Se, 103 Rh, DRC reaction gas: CH 4 reaction at 0.58 ml/min, DRC rejection parameter q: 0.6.…”

Plasma Selenium Concentrations Are Sufficient and Associated with Protease Inhibitor Use in Treated HIV-Infected Adults

“…However, recent data suggest that these deficiencies are also prevalent among the overweight and obese. Specifically, it has been shown that obese individuals have lower selenium concentrations than leaner individuals (33,34). Further, Combs et al (18) have suggested that there is a quadratic relation between selenium and BMI, with selenium concentrations being lower in individuals at the low and high ends of the BMI range.…”

Association Between Serum Selenium Concentrations and Levels of Proinflammatory and Profibrotic Cytokines - Interleukin-6 and Growth Differentiation Factor-15, in Patients with Alcoholic Liver Cirrhosis

“…Each time an acidic digestion with 65 % nitric acid water solution was applied (1mL of HNO3 : 9 mL of deionized H2O). The optimized conditions of the mineralization procedure had been previously published [8]. The obtained solutions were poured into volumetric flasks (PTFE) and diluted with deionized water (18 MΩ cm) whenever necessary before final analysis.…”
