Cigarette smoking promotes body weight reduction in humans while paradoxically also promoting insulin resistance (IR) and hyperinsulinemia. However, the mechanisms behind these effects are unclear. Here we show that nicotine, a major constituent of cigarette smoke, selectively activates AMP-activated protein kinase α2 (AMPKα2) in adipocytes, which in turn(More)
A prolonged or excessive adrenergic activation leads to myocyte loss and heart dysfunction; however, how it contributes to heart failure remains poorly defined. Here we show that isoproterenol (ISO) induced aberrant endoplasmic reticulum (ER) stress and apoptotic cell death, which was inhibited by activating the AMP-activated protein kinase (AMPK) in vitro(More)
In development of a speaker verification system, a priori threshold estimation is often needed based on a training set for decision making. Such a threshold critically determines performance of a speaker verification system. From a statistical viewpoint, a speaker's voice could be modeled by a certain distribution. Thus, data for training are only some(More)
The inflammatory response after polymer-based drug-eluting stent (DES) placement has recently emerged as a major concern. The biologic roles of peroxisome proliferator-activated receptor-γ (PPAR-γ) activators thiazolidinedione (TZD) remain controversial in cardiovascular disease. Herein, we investigated the antiinflammatory effects of pioglitazone (PIO) on(More)
