CONTEXT: High glucose generates reactive oxygen species (ROS) and contributes to glucotoxicity in hepatocytes, and hyperglycemia causes structural and functional damage to the liver. However, only a mild hepatic dysfunction was observed in subjects with hyperglycemic crisis, implying a factor exists to exert a hepatic protective effect. Hepassocin is a hepatokine that modulates the proliferation and metabolism of hepatocytes, and also exerts protective activity in liver injury. However, its role in hyperglycemic crisis-induced hepatic dysfunction remains unknown...

Background: Roux-en-Y gastric bypass (RYGB) surgery is currently the most effective treatment for obesity, although limited by availability and operative risk. The gut hormones Glucagon-like peptide-1 (GLP-1), Peptide YY (PYY) and Oxyntomodulin (OXM) are elevated post-prandially after RYGB, which has been postulated to contribute to its metabolic benefits. Objective: We hypothesised that infusion of the three gut hormones to achieve levels similar to those encountered post-prandially in RYGB patients might be effective in suppressing appetite...
