Delphinidin anthocyanins have previously been associated with the inhibition of glucose absorption. Blood glucose lowering effects have been ascribed to maqui berry (Aristotelia chilensis) extracts in humans after boiled rice consumption. In this study, we aimed to explore whether a standardized delphinidin-rich extract from maqui berry (Delphinol) affects glucose metabolism in prediabetic huma...

Before having received any insulin, the serum insulin level was abnormally low in relation to the blood glucose level (Table). At the time of diagnosis some degree of insensitivity to insulin was suggested since injection of 2 units crystalline insulin intravenously (1 0 unit/kg) caused a less than 50% decrease in blood sugar concentration after 30 minutes. The necessity for insulin treatment f...

OBJECTIVE Individuals with normal glucose tolerance (NGT), whose 1-h postload plasma glucose is ≥155 mg/dL (NGT 1h-high), have an increased risk of type 2 diabetes. The purpose of this study was to characterize their metabolic phenotype. RESEARCH DESIGN AND METHODS A total of 305 nondiabetic offspring of type 2 diabetic patients was consecutively recruited. Insulin secretion was assessed usin...

The total prevalence of diabetes and impaired glucose tolerance in U.S. adults aged 20-74 years was obtained from medical history and oral glucose tolerance tests. Plasma glucose distributions, associations with selected medical, genetic, and clinical characteristics, and comparisons with prevalence in the 1976 National Health Interview Survey are also presented.

The authors assessed the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) according to the 1980 National Diabetes Data Group (1980 NDDG) classification and diagnosis. Two hundred and sixty inhabitants [aged 50.9 +/- 9.6 years, male: female (M:F) = 90: 170] of five small rural towns in Kumamoto Prefecture (population 1.8 million) and 279 male members of western divisions...

INTRODUCTION Several studies have assessed the impact of the 1997 American Diabetes Association (ADA) recommendation, of using fasting plasma glucose (FPG) concentration, to diagnose diabetes mellitus in population-based cohorts. However, data concerning the impact of this recommendation in the hospital setting are limited. As the performance characteristics of diagnostic tests vary depending o...

Impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) represent intermediate states between normal fasting glucose (NFG) or normal glucose tolerance (NGT), respectively, and diabetes (1). The regulation of fasting and glucose concentrations after an oral glucose load is dependent on different physiological mechanisms (2), and current evidence suggests that IFG and IGT have differe...
