The effects of raised brain lactate levels on neuronal survival following hypoxia or ischemia is still a source of controversy among basic and clinical scientists. We have sought to address this controversy by studying the effects of glucose and lactate on neuronal survival in acute and cultured hippocampal slices. Following a 1-h hypoxic episode, neuronal survival in cultured hippocampal slice...

OBJECTIVE The goal was to assess the 1-year efficacy and safety of the addition of pioglitazone or metformin to existing sulfonylurea (SU) therapy in patients with inadequately controlled type 2 diabetes. RESEARCH DESIGN AND METHODS In this multicenter, double-blind study, patients were randomized to receive either pioglitazone 15 mg (n = 319) or metformin 850 mg (n = 320) and up to 45 mg/day...

Aim. The purpose of this study was to investigate the effects of pioglitazone on oxidative stress and the expressions of p22(phox) and p47(phox), subunits of NADPH oxidase, in mesangial cells (MCs). Method. Rat mesangial cells were cultured and randomly divided into normal glucose (NG) group, high glucose (HG) group, and pioglitazone group. After 48 h exposure, the supernatants and cells were c...
