Loss-of-Function Mutation in Toll-Like Receptor 4 Prevents Diet-Induced Obesity and Insulin Resistance
Obesity is associated with insulin resistance and a state of abnormal inflammatory response. The Toll-like receptor (TLR)4 has an important role in inflammation and immunity, and its expression has… Expand

S-nitrosation of the insulin receptor, insulin receptor substrate 1, and protein kinase B/Akt: a novel mechanism of insulin resistance.
Evidence demonstrates that exogenous nitric oxide (NO) and the NO produced by inducible nitric oxide synthase (iNOS) can induce insulin resistance in muscle. Here, we investigated whether this… Expand

Double-stranded RNA-activated protein kinase is a key modulator of insulin sensitivity in physiological conditions and in obesity in mice.
The molecular integration of nutrient- and pathogen-sensing pathways has become of great interest in understanding the mechanisms of insulin resistance in obesity. The double-stranded RNA-dependent… Expand

Targeted Disruption of Inducible Nitric Oxide Synthase Protects Against Aging, S-Nitrosation, and Insulin Resistance in Muscle of Male Mice
Accumulating evidence has demonstrated that S-nitrosation of proteins plays a critical role in several human diseases. Here, we explored the role of inducible nitric oxide synthase (iNOS) in the… Expand

Insulin signalling pathways in aorta and muscle from two animal models of insulin resistance—the obese middle-aged and the spontaneously hypertensive rats
Aims/hypothesisThe aim of this study was to investigate insulin signalling pathways directly in vivo in skeletal muscle and thoracic aorta from obese middle-aged (12-month-old) rats, which have… Expand

Acute physical exercise reverses S‐nitrosation of the insulin receptor, insulin receptor substrate 1 and protein kinase B/Akt in diet‐induced obese Wistar rats
Early evidence demonstrates that exogenous nitric oxide (NO) and the NO produced by inducible nitric oxide synthase (iNOS) can induce insulin resistance. Here, we investigated whether this insulin… Expand

Aspirin attenuates insulin resistance in muscle of diet-induced obese rats by inhibiting inducible nitric oxide synthase production and S-nitrosylation of IRβ/IRS-1 and Akt
Aim/hypothesisHigh-dose aspirin treatment improves fasting and postprandial hyperglycaemia in patients with type 2 diabetes, as well as in animal models of insulin resistance associated with obesity… Expand

Modulation of Double‐Stranded RNA‐Activated Protein Kinase in Insulin Sensitive Tissues of Obese Humans
Objective: The double‐stranded RNA‐dependent protein kinase (PKR) was recently implicated in regulating molecular integration of nutrient‐ and pathogen‐sensing pathways in obese mice. However, its… Expand

Physicians' self-assessed empathy levels do not correlate with patients' assessments
Background Empathy is a fundamental humanistic component of patient care which facilitates efficient and patient-centered clinical encounters. Despite being the principal recipient of physician… Expand
