OBJECTIVE To assess the role of adiposity on the pharmacodynamics of basal insulins NPH, detemir, and glargine in type 2 diabetes mellitus (T2DM), as estimated by glucose infusion rate (GIR) and endogenous glucose production (EGP) rate in the euglycemic clamp. RESEARCH DESIGN AND METHODS We examined the variables that best predicted GIR and EGP in 32-h clamp studies after treatment with subcu...

The main purpose of this study was to examine the citation patterns of discussion sections employed by local and international article writers in ESP and EGP subdisciplines of applied linguistics. Eighty article discussion sections were selected from well-established local and international journals in the field of applied linguistics, and they were sorted according to Thompson and Tribble’s (2...

A total of 8 obese subjects with type 2 diabetes were studied while on a eucaloric diet and after reduced energy intake (25 and then 75% of requirements for 10 days each). Weight loss was 2, 3, and 3 kg after 5, 10, and 20 days, respectively; all of the weight lost was body fat. Fasting blood glucose (FBG) levels fell from 11.9 +/- 1.4 at baseline to 8.9 +/- 1.6, 7.9 +/- 1.4, and 8.8 +/- 1.3 mm...

To determine whether the insulin dose-response curves for suppression of endogenous glucose production (EGP) and stimulation of splanchnic glucose uptake (SGU) differ in nondiabetic humans and are abnormal in type 2 diabetes, 14 nondiabetic and 12 diabetic subjects were studied. Glucose was clamped at approximately 9.5 mmol/l and endogenous hormone secretion inhibited by somatostatin, while glu...

The mechanisms of the impairment in hepatic glucose metabolism induced by free fatty acids (FFAs) and the importance of FFA oxidation in these mechanisms remain unclear. FFA-induced peripheral insulin resistance has been linked to membrane translocation of novel protein kinase C (PKC) isoforms, but the role of PKC in hepatic insulin resistance has not been assessed. To investigate the biochemic...

OBJECTIVE Subthalamic nucleus-deep brain stimulation (STN-DBS) is an alternative treatment for patients with uncontrolled symptoms of Parkinson's disease (PD), but it has other nonmotor impact. Because STN-DBS alters the energy expenditure in humans, we hypothesized that STN-DBS may affect postabsorptive glucose metabolism in patients with PD. RESEARCH DESIGN AND METHODS Endogenous glucose pr...

Induction of T-cell activation requires multiple signals provided by cell surface receptor interactions and/or cytokines. T-cell stimulation via the T-cell receptor/CD3 complex provides an important initial activation event which, when combined with the proper costimulatory signals, re sults in an activated effector T cell. In this report, we have investigated the effectiveness of epithelial gl...

Evidence, gained from human studies, is reviewed showing that elevation of plasma FFA levels produce peripheral and probably also hepatic insulin resistance in obese healthy and diabetic subjects. First, plasma FFA levels are elevated in most obese subjects. Second, physiological elevations of plasma FFA inhibit acutely as well as chronically insulin stimulated glucose uptake in a dose dependen...

Obesity is a risk factor for type 2 diabetes in cats. The risk of developing diabetes is severalfold greater for male cats than for females, even after having been neutered early in life. The purpose of this study was to investigate the role of different metabolic pathways in the regulation of endogenous glucose production (EGP) during the fasted state considering these risk factors. A triple t...

OBJECTIVE Glucagon delivery in closed-loop control of type 1 diabetes is effective in minimizing hypoglycemia. However, high insulin concentration lowers the hyperglycemic effect of glucagon, and small doses of glucagon in this setting are ineffective. There are no studies clearly defining the relationship between insulin levels, subcutaneous glucagon, and blood glucose. RESEARCH DESIGN AND M...
