Zinc and smoking habits in the setting of hypertension in a Spanish populations.
2014
The objective of this study was to evaluate the relationship between trace and toxic amounts of zinc (Zn) in biological samples (blood and urine) and the smoking habits of hypertensive patients and healthy control subjects in Valladolid (Spain). In order to compare biological samples, the concentrations of these samples were measured using inductively coupled plasma mass spectrometry. The limits of detection for Zn in blood plasma ranged between 4.22 and 17.34 μmol l(-1) and were <0.08 μmol g(-1) creatinine in urine. The results of this study indicate that the highest mean values of serum Zn were found in non-hypertensive nonsmokers (13.39±4.35 μmol l(-1)), whereas the highest urine Zn valu…
Plasma selenium levels and oxidative stress biomarkers: a gene-environment interaction population-based study.
2014
The role of selenium exposure in preventing chronic disease is controversial, especially in selenium-repleted populations. At high concentrations, selenium exposure may increase oxidative stress. Studies evaluating the interaction of genetic variation in genes involved in oxidative stress pathways and selenium are scarce. We evaluated the cross-sectional association of plasma selenium concentrations with oxidative stress levels, measured as oxidized to reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), and 8-oxo-7,8-dihydroguanine (8-oxo-dG) in urine, and the interacting role of genetic variation in oxidative stress candidate genes, in a representative sample of 1445 men and women…
Correlation of Zinc with Oxidative Stress Biomarkers
2015
Hypertension and smoking are related with oxidative stress (OS), which in turn reports on cellular aging. Zinc is an essential element involved in an individual’s physiology. The aim of this study was to evaluate the relation of zinc levels in serum and urine with OS and cellular aging and its effect on the development of hypertension. In a Spanish sample with 1500 individuals, subjects aged 20–59 years were selected, whose zinc intake levels fell within the recommended limits. These individuals were classified according to their smoking habits and hypertensive condition. A positive correlation was found (Pearson’s C = 0.639
