Many studies have shown that hyperinsulinemia and/or insulin resistance are related to various metabolic and physiological disorders including hypertension, dyslipidemia, non-insulin-dependent diabetes mellitus. This syndrome has been termed Syndrome X. An important limitation of previous they all cross sectional, thus the presence could be a consequence underlying rather than its cause. We examined relationship fasting concentration (as an indicator resistance) incidence multiple...
Although type II diabetes is associated with both microvascular and macrovascular complications, duration of severity glycemia are strongly only the former. Since prediabetic individuals hyperinsulinemia, since hyperinsulinemia may be a cardiovascular risk factor, we hypothesized that might have an atherogenic pattern factors even before onset clinical diabetes, thereby explaining relative lack association complications either glycemic or disease duration. We documented factor status 614...
Apolipoprotein C-III (apoC-III) inhibits triglyceride hydrolysis and has been implicated in coronary artery disease. Through a genome-wide association study, we have found that about 5% of the Lancaster Amish are heterozygous carriers null mutation (R19X) gene encoding apoC-III ( APOC3 ) and, as result, express half amount present noncarriers. Mutation compared with noncarriers had lower fasting postprandial serum triglycerides, higher levels HDL-cholesterol LDL-cholesterol. Subclinical...
The ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Consortium was set up to analyze brain measures and genotypes from multiple sites across the world improve power detect genetic variants that influence brain. Diffusion tensor imaging (DTI) yields quantitative sensitive development degeneration, some common may be associated with white matter integrity or connectivity. DTI measures, such as fractional anisotropy (FA) of water diffusion, useful for identifying microstructure....
Few data exist on predictors of non-insulin-dependent (type II) diabetes mellitus. We examined body mass index (BMI), ratio subscapular-to-triceps skin fold (centrality index), and fasting glucose insulin concentrations as decompensation to type II in Mexican Americans, a population at high risk for this disorder. Twenty-eight 474 initially nondiabetic Americans developed after 8 yr follow-up. Converters were older had higher BMIs, centrality indices, than nonconverters. Subjects the highest...
The familial aggregation of coronary heart disease can be in large part accounted for by a clustering cardiovascular risk factors. To elucidate the determinants disease, many epidemiological studies have focused on behavioral and lifestyle these factors, whereas others examined whether specific candidate genes influence quantitative variation phenotypes.Among Mexican Americans from San Antonio (Tex), we quantified relative contributions both genetic environmental influences to panel...
Telomere length (TL) is emerging as a biomarker for aging and survival. To evaluate factors influencing this trait, we measured TL in large homogeneous population, estimated the heritability (h(2)), tested parental effects on variation. Our sample included 356 men 551 women, aged 18-92 years, from Amish families. Mean leukocytes was by quantitative PCR (mean: 6,198 +/- 1,696 bp). The h(2) of 0.44 0.06 (P < 0.001), after adjusting age, sex, assay batch. As expected, negatively correlated with...
Migraine with aura is associated ischemic stroke, but few studies have investigated the clinical and anatomic features of this association. We assessed association probable migraine without visual stroke within subgroups defined by subtype, vascular territory, characteristics, other features.Using data from a population-based, case-control study, we studied 386 women ages 15 to 49 years first 614 age- ethnicity-matched controls. Based on their responses questionnaire headache symptoms,...
Hypertension places a major burden on individual and public health, but the genetic basis of this complex disorder is poorly understood. We conducted genome-wide association study systolic diastolic blood pressure (SBP DBP) in Amish subjects found strong signals with common variants serine/threonine kinase gene, STK39 . confirmed an independent 4 non-Amish Caucasian samples including Diabetes Genetics Initiative, Framingham Heart Study, GenNet, Hutterites (meta-analysis combining all...
