Obesity is a risk factor for metabolic syndrome, dyslipidemia, hypertension, insulin resistance, type 2 diabetes mellitus, and cardiovascular disease. However, obesity is not a homogenous state and not all subjects in an obese population are at an increased risk for metabolic abnormalities. Thus, obesity types can be subdivided into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) according to metabolic status. Body minerals are important and are involved in various metabolic processes that may be related to obesity. Thus, this study determined whether hair mineral concentrations differ between MHO and MUO adults. The associations between metabolic risk factors and hair mineral concentrations were analyzed in 141 obese Korean adults (62 MHO subjects and 79 MUO subjects). The MUO subjects showed significantly higher triglyceride levels, systolic blood pressure, waist circumference and body mass index, lower high-density lipoprotein cholesterol levels, and greater insulin resistance as reflected by the homeostasis model assessment-insulin resistance (HOMA-IR) index compared with MHO subjects. No significant differences in hair mineral concentrations were detected between MHO and MUO adults. Hair iron and cobalt concentrations were significantly negatively correlated with blood pressure in subjects with MHO. In addition, hair zinc concentration was associated with decreased systolic blood pressure. The results of this study suggest that mineral status in obese adults may play a role in metabolic abnormalities. Further studies with a larger number of subjects are warranted to identify the nature of the relationship between hair mineral status and metabolic risk in MHO and MUO subjects.

Occupational exposure to metals can have an adverse effect on the cardiovascular system. However, epidemiological studies of the associations of metals expose with hypertension among occupationally exposed workers were limited. The aim of this study was to investigate the potential association between urinary metal levels and the risk of hypertension among molybdenum miners and iron and steel foundry workers. The cross-sectional study had 395 participants. Urinary metal levels were determined by inductively coupled plasma mass spectrometry. Log-binomial regression model and two-piece-wise regression model were applied to assess the dose-response relationship between metal exposure and hypertension. We observed that increased prevalence ratios for hypertension among the quartile of urinary concentrations of molybdenum, arsenic and lead were positive (all P for trend <0.05). Compared with the lowest quartiles, participants in the highest quartiles of molybdenum, arsenic and lead had a 2.58-fold, 4.30-fold and 4.85-fold increased probability of having hypertension, respectively. In the threshold effect analyses, we found the relationship was nonlinear between urinary molybdenum, cobalt, cadmium, arsenic and lead concentrations and the prevalence of hypertension. In addition, Pb, Mo, As and Co may have joint effect, and a strong positive correlation with the prevalence of hypertension. Conversely, the association between the joint effect of Cd, Pb and Mo versus the prevalence of hypertension is not significant. We provide reference levels of molybdenum, cobalt, cadmium, arsenic and lead that can be used to assess the effects of occupational metal exposure on hypertension.

A new bifunctional chemosensor HBP ((E)-2-(2-((5-bromopyridin-2-yl)methylene)hydrazinyl) quinoline) based on heterocyclic compounds was designed and studied. The HBP showed successful detecting ability toward cobalt ion with a UV-visible red-shift and a color change of colorless to pink. Moreover, toward zinc ion, the HBP showed an obvious fluorescence turn-on response. The binding ratio of the HBP to cobalt and zinc was a 2 to 1 for both ions. The detection limits were found to be 10 nM for Co2+ and 18 nM for Zn2+. Based on UV-vis and fluorescent spectral variations, Job plots, ESI-MS, FT-IR and calculations, the binding mechanisms of the HBP toward cobalt and zinc ions were proposed.
