Multiple genetic loci associated with obesity or body mass index (BMI) have been identified through genome-wide association studies conducted predominantly in populations of European ancestry. We performed a meta-analysis of associations between BMI and approximately 2.4 million SNPs in 27,715 east Asians, which was followed by in silico and de novo(More)
To further understanding of the genetic basis of type 2 diabetes (T2D) susceptibility, we aggregated published meta-analyses of genome-wide association studies (GWAS), including 26,488 cases and 83,964 controls of European, east Asian, south Asian and Mexican and Mexican American ancestry. We observed a significant excess in the directional consistency of(More)
Chronic elevation of plasma aldosterone contributes to heart failure. Mineralocorticoid receptor (MR) antagonism is cardioprotective in such a setting, but whether such protection occurs in the presence of low-aldosterone concentrations remains unclear. We investigated whether MR blockade attenuates cardiac hypertrophy and failure in rats with(More)
Multifactorial disease such as life style related diseases, for example, cancer, diabetes mellitus, myocardial infarction (MI) and others, is thought to be caused by complex interactions between polygenic basis and various environmental factors. In this study, we used 22 polymorphisms on 16 candidate genes that have been characterized and potentially(More)
BACKGROUND/OBJECTIVE In Japanese populations, we performed a replication study of genetic loci previously identified in European-descent populations as being associated with lipid levels and risk of coronary artery disease (CAD). METHODS We genotyped 48 single nucleotide polymorphisms (SNPs) from 22 candidate loci that had previously been identified by(More)
OBJECTIVES Oxidative stress is implicated in the pathogenesis of heart failure and affects the activity of matrix metalloproteinases (MMPs). We have now investigated the role of MMPs and their tissue inhibitors (TIMPs) in the transition from compensated left ventricular (LV) hypertrophy to heart failure as well as the effects of pravastatin on this(More)
OBJECTIVE The mammalian heart contains specific growth hormone-releasing peptide (GHRP) binding sites whose physiological significance is unknown. We sought to compare the effects of GHRP and GH on progressive left ventricular (LV) dysfunction in the TO-2 hamster model of dilated cardiomyopathy. METHODS TO-2 hamsters (8 weeks old) were injected with(More)
Genome-wide association studies have identified many genetic loci associated with blood pressure (BP). Genetic effects on BP can be altered by environmental exposures via multiple biological pathways. Especially, obesity is one of important environmental risk factors that can have considerable effect on BP and it may interact with genetic factors. Given(More)
—The effective permittivity of the one-dimensional periodic structure is examined using the reflectance and trans-missivity obtained by the FDTD method. By using the reflectance and transmissivity by the FDTD method, the effective permittivity of the dielectric slab, which has the same reflectance and transmissivity with that of periodic structure, is(More)
