BACKGROUND Insulin resistance has a causal role in type 2 diabetes. Serum levels of retinol-binding protein 4 (RBP4), a protein secreted by adipocytes, are increased in insulin-resistant states. Experiments in mice suggest that elevated RBP4 levels cause insulin resistance. We sought to determine whether serum RBP4 levels correlate with insulin resistance(More)
BACKGROUND New treatments for type 2 diabetes mellitus are needed to retain insulin-glucose coupling and lower the risk of weight gain and hypoglycaemia. We aimed to investigate the safety and efficacy of liraglutide as monotherapy for this disorder. METHODS In a double-blind, double-dummy, active-control, parallel-group study, 746 patients with early(More)
OBJECTIVE This study evaluated the ability of the incretin mimetic exenatide (exendin-4) to improve glycemic control in patients with type 2 diabetes failing maximally effective doses of a sulfonylurea as monotherapy. RESEARCH DESIGN AND METHODS This was a triple-blind, placebo-controlled, 30-week study conducted at 101 sites in the U.S. After a 4-week,(More)
BURG is a program that generates a fast tree parser using BURS (Bottom-Up Rewrite System) technology. It accepts a cost-augmented tree grammar and emits a C program that discovers in linear time an optimal parse of trees in the language described by the grammar. BURG has been used to construct fast optimal instruction selectors for use in code generation.(More)
To determine whether the serine/threonine kinase Akt (also known as protein kinase B) is activated in vivo by insulin administration in humans, and whether impaired activation of Akt could play a role in insulin resistance, we measured the activity and phosphorylation of Akt isoforms in skeletal muscle from 3 groups of subjects: lean, obese nondiabetic, and(More)
T ype 2 diabetes is now epidemic. In the U.S., there has been a 61% increase in incidence between 1990 and 2001 (1). There are currently 1.5 million new cases per year, and the prevalence in 2005 was almost 21 million (2). The epidemic has affected developed and developing countries alike, and the worldwide prevalence of diabetes is projected to increase(More)
BACKGROUND Combining metformin (XR) with dapagliflozin to initiate pharmacotherapy in patients with type 2 diabetes (T2D) and high baseline HbA1c may be advantageous. We conducted two randomised, double-blind, three-arm 24-week trials in treatment-naïve patients to compare dapagliflozin plus metformin, dapagliflozin alone and metformin alone. METHODS(More)
To achieve high performance in uniprocessor RISC systems, compilers must perform both register allocation to reduce memory references and instruction scheduling to avoid pipeline hazards. Compilers that separate the two functions should perform poorly on uniprocessor RISCS that support multi-cycle operations, particularly on computation-intensive workloads.(More)
BACKGROUND Impaired glucose tolerance is associated with increased rates of cardiovascular disease and conversion to type 2 diabetes mellitus. Interventions that may prevent or delay such occurrences are of great clinical importance. METHODS We conducted a randomized, double-blind, placebo-controlled study to examine whether pioglitazone can reduce the(More)
BACKGROUND & AIMS Obeticholic acid (OCA; INT-747, 6α-ethyl-chenodeoxycholic acid) is a semisynthetic derivative of the primary human bile acid chenodeoxycholic acid, the natural agonist of the farnesoid X receptor, which is a nuclear hormone receptor that regulates glucose and lipid metabolism. In animal models, OCA decreases insulin resistance and hepatic(More)
