The Role of Cholinergic Signaling for Mediating the Effects of GIP and/or Xenin-25 on Insulin Secretion

"Starting at 0 minutes, glucose infusion rates will be increased to 1, 2, 3, 4, 6, and 8 mg/kg/min every 40 minutes. The study is finished at 240 minutes.~Starting at 0 minutes, an intravenous infusion of saline containing 1% human albumin will continue for 240 minutes."

"Starting at 0 minutes, glucose infusion rates will be increased to 1, 2, 3, 4, 6, and 8 mg/kg/min every 40 minutes. The study is finished at 240 minutes.~Following a priming dose from 0-10 minutes, xenin-25 (in saline containing 1% human albumin) will be administered at a constant dose of 4 pmoles/kg/min until 240 minutes."
