Hypocretins (Hcrts), or orexins, are a recently described set of hypothalamic peptides that have been implicated in feeding, neuroendocrine regulation, sleep-wakefulness, and disorders of sleep, such as narcolepsy. Hcrt-containing neurons, which are located exclusively in the lateral hypothalamic area, provide a dense innervation to the medial(More)
OBJECTIVES Roux-en-Y gastric bypass (RYGB) is a novel therapy for diabetes. We aimed to explore the therapeutic mechanism of RYGB. METHODS After RYGB, animal models were established, and gene expression profile of islets was assessed. Additionally, gastrointestinal hormones were measured using enzyme-linked immunosorbent assays. Ca(2+) was studied using(More)
BACKGROUND The aim of this study was to develop an antiGPC3-ultrasuperparamagnetic iron oxide (USPIO) probe for early detection of hepatocellular carcinoma. METHODS GPC3 and AFP receptors were selected as biomarkers and conjugated with USPIO nanoparticles coated by dextran with carboxylate groups to synthesize antiGPC3-USPIO and antiAFP-USPIO probes.(More)
