Previously, we reported that aphidicolin acutely increases nitric oxide (NO) production in bovine aortic endothelial cells (BAECs) by increasing phosphorylation of endothelial nitric oxide synthase at serine 1179 (p-eNOS-Ser1179) and decreasing phosphorylation at serine 116 (p-eNOS-Ser116) without altering eNOS protein expression. Here, we demonstrate that prolonged treatment with aphidicolin (over 24 h) also increased NO production in BAECs. Unlike the a...

Object: The natural history and proper algorithm for follow-up testing of nonfunctioning pituitary adenomas (NFPAs) are not well known, despite their relatively high prevalence. The aim of this study was to suggest the optimal follow-up algorithm for NFPAs, based on the natural history.Methods: We followed up on 197 patients with NFPAs without any treatment (including surgery and radiation) at the time of detection, in a single center, between March 2000...

Recently, dipeptidyl peptidase-IV (DPP-IV) inhibitor, a major anti-hyperglycaemic agent, has received substantial attention as a possible therapeutic target for inflammatory diseases such as atherosclerosis. However, the direct molecular mechanisms through which DPP-IV inhibitor mediates anti-inflammatory effects in vascular endothelial cells have not been clarified. The effects of the DPP-IV inhibitor, gemigliptin, were analysed in human umbilical vein endothelial cells (HUVE...
