AIMS To compare the efficacy and tolerability of the dipeptidyl peptidase-4 inhibitor, vildagliptin, with the alpha glucosidase inhibitor, acarbose, in drug-naive patients with Type 2 diabetes. METHODS This multi-centre, randomized, double-blind, parallel-arm study compared the efficacy and tolerability of vildagliptin (100 mg daily, given as 50 mg twice(More)
Insulin stimulation of phosphatidylinositol (PI) 3-kinase activity is defective in skeletal muscle of type 2 diabetic individuals. We studied the impact of antidiabetic therapy on this defect in type 2 diabetic subjects who failed glyburide treatment by the addition of troglitazone (600 mg/day) or metformin (2,550 mg/day) therapy for 3-4 months. Improvement(More)
Pasireotide (SOM230) is a novel multireceptor-targeted somatostatin (sst) analog with high binding affinity for sst receptor subtype 1, 2, 3 (sst(1,2,3)) and sst(5). Because of this binding profile, pasireotide may offer symptom control in patients with neuroendocrine tumors (NETs) and carcinoid syndrome no longer responsive to octreotide LAR. This was a(More)
Glycogen synthase (GS) activity is reduced in skeletal muscle of type 2 diabetes, despite normal protein expression, consistent with altered GS regulation. Glycogen synthase kinase-3 (GSK-3) is involved in regulation (phosphorylation and deactivation) of GS. To access the potential role of GSK-3 in insulin resistance and reduced GS activity in type 2(More)
CONTEXT Pasireotide (SOM230) is a novel multireceptor ligand somatostatin analog with affinity for somatostatin receptor subtypes sst(1-3) and sst(5). Because most GH-secreting pituitary adenomas express sst(2) and sst(5), pasireotide has the potential to be more effective than the sst(2)-preferential somatostatin analogs octreotide and lanreotide.

Weight-loss interventions generally improve lipid profiles and reduce cardiovascular disease risk, but effects are variable and may depend on genetic factors. We performed a genetic association analysis of data from 2,993 participants in the Diabetes Prevention Program to test the hypotheses that a genetic risk score (GRS) based on deleterious alleles at 32(More)
AIM This double-blind study evaluated the efficacy and safety of metformin-glibenclamide tablets vs. metformin plus rosiglitazone therapy in patients with type 2 diabetes inadequately controlled on metformin monotherapy. SUBJECTS AND METHODS After an open-label, metformin lead-in phase, 318 patients were randomly assigned to treatment based on(More)
A randomized, double-blind, placebo-controlled, cross-over, dose-escalating, single-center study was conducted to evaluate the safety, tolerability, and pharmacokinetic (PK) profile of multiple once-daily (qd) subcutaneous (sc) doses of pasireotide in healthy male subjects. Subjects received pasireotide 50, 200, or 600 μg sc qd for 14 days and placebo in(More)
OBJECTIVE We sought to evaluate the effects of muraglitazar, a dual (alpha/gamma) peroxisome proliferator-activated receptor (PPAR) activator within the new glitazar class, on hyperglycemia and lipid abnormalities. RESEARCH DESIGN AND METHODS A double-blind, randomized, controlled trial was performed in 1,159 patients with type 2 diabetes inadequately(More)
The purpose of this study was to determine if 100% O2 would enhance rat pulmonary alveolar macrophage (PAM) oxidative killing of conidia of the fungus Neurospora crassa. First, we found that incubation in 100% O2 had no effect on conidia viability in the absence of PAM. We obtained resident PAM from nonpretreated anesthetized male Sprague-Dawley rats by(More)
