Serum human pancreatic polypeptide (hPP) responses to 50 gm. of oral glucose and a 25 gm. intravenous bolus of glucose were measured in 10 healthy human volunteers. Oral glucose caused a 50% rise, whereas I.V. glucose caused a .3.5% fall in hPP concentration. There was no relationship between the absolute glucose concentration or the change in glucose level and the PP concentration. It is suggested that oral and I.V. glucose affect PP by indirect mechanisms and that PP may be involved in carbohydrate metabolism in man.

    The purpose of this study was to determine if lowering carbohydrate (CHO) concentration in a sport drink influences gastric emptying, intestinal absorption, or performance during cycle ergometry (85 min, 60% VO2peak). Five subjects (25 ± 1 y, 61.5 ± 2.1 mL · kg-1 · min-1 VO2peak)...

    Diabetes has been inconsistently associated with increased risk of venous thromboembolism (VTE) and there is little direct evidence on the associations of glycemia levels with VTE. We used data from the Atherosclerosis Risk in Communities study to test the hypothesis that glycemia, as measured...
