METHODS: A total of 916 MHAO subjects

from the Tehran Lipid and Glucose Study were followed for changes in their metabolic health status. Anthropometric and metabolic indices were measured at baseline and were compared between subjects with healthy and unhealthy metabolic conditions at the end of follow-up. Predictors of change in metabolic health were assessed in logistic regression models. National waist circumference cutoffs were used for definition of abdominal obesity. Metabolic health was defined as smaller than = 1 metabolic components of metabolic syndrome according to the Joint Interim Statement criteria. RESULTS: At the end of the follow-up, nearly selleck products half of the MHAO subjects lost their metabolic health and 42.1% developed metabolic syndrome by definition. Low high-density lipoprotein cholesterol, hypertriglyceridemia and homeostasis model assessment-insulin resistance at baseline were significant predictors of change in metabolic health condition. CONCLUSION: MHAO is a relatively unstable condition and a considerable percentage of these individuals will lose their metabolic health as time passes. Baseline

metabolic characteristics may be useful predictors of this KU57788 change and should be considered in the care of these individuals.”
“The zebra mussel Dreissena polymorpha is widely used as sentinel organism for the assessment of environmental contamination in freshwater environments. However, in the River SB203580 research buy Rhine (Germany), the D. polymorpha population is declining, whereas the closely related quagga mussel D. bugensis is found

in high numbers at some sites. In the present laboratory study, D. polymorpha and D. bugensis were exposed to resuspended native sediments for a parts per thousand currency sign2 weeks. Wet sediments (< 63 mu m, 100 mg l(-1) dry weight) were used as surrogate suspended particulate matter to mimic one of the mussels’ main uptake route for chemicals. The sediments were sampled in (1) the River Elbe in Dessau, a site known to be highly polluted with, e.g., organochlorine (OC) pesticides and (2) at a relatively unpolluted site in Havelberg in the River Havel, one of the Elbe’s tributaries. Chemical analysis of persistent OC compounds (seven polychlorinated biphenyls [PCBs], DDT and its metabolites (DDX), hexachlorocylohexanes [HCHs], and hexachlorobenzene [HCB]) in soft tissue of mussels showed significantly greater values of PCBs 101, 118, 153, 138, 180, the sum of seven PCBs, and p,p’-DDD in D. bugensis compared with D. polymorpha. Fourteen days of exposure to Dessau sediment increased the concentration of p,p’-DDE and p,p’-DDD, as well as the sum of DDX, in both species compared with Havelberg sediment.
