Obesity is a major public health issue worldwide. Current pharmacological treatments are largely unsuccessful. Determining the complex pathways that regulate food intake may aid the development of new treatments. The hypothalamic-pituitary-thyroid (HPT) axis has well-known effects on energy expenditure, but its role in the regulation of food intake is less well characterised. Evidence suggests ...

The central mechanism controlling food intake in response to the change in environmental temperature has been little examined. The GABA agonist, muscimol, was injected into the lateral ventricle of rats which were acclimated to temperate (26 degrees C) and hot (33 degrees C) environments. Muscimol obviously stimulated the feeding behavior of rats in both environments. However, when muscimol was...

The purpose of this investigation was to study the effects of continuous Intralipid infusions on serum HDL and LDL levels in the rat. Male Fischer 344 rats were infused continuously via central venous catheter with 10% Intralipid for 96 h and 5, or 2.5% Intralipid for 14 days. Blood samples were collected during the infusion period for total serum cholesterol, HDL-, and LDL-cholesterol measurem...

Obesity has received much attention worldwide in association with an increased risk of cardiovascular diseases, diabetes, and cancer. At present, bariatric surgery is the only effective treatment for obesity in which long-term weight loss is achieved in patients. By contrast, pharmacological interventions for obesity are usually followed by weight regain. Although the exact mechanisms of long-t...

Obesity is rapidly increasing and is of great public health concern worldwide. Although there have been remarkable developments in obesity research over the past 10 years, the molecular mechanism of obesity is still not completely understood. Body weight results from the balance between food intake and energy expenditure. Recent studies have found that hypothalamic AMP-activated protein kinase ...

background: cardiovascular disease is a major cause of death throughout the world. the aim of this study was to as­sess the prevalence of overweight/obesity, central obesity, hypertension and dyslipidemia, as well as dietary factors contribut­ing to the development of dyslipidemia among middle-aged women. methods: the research design of the present study was a population-based cross-sectional s...

BACKGROUND Few animal experiments and volunteer-based intervention studies have showed a controversial effect of spicy foods on weight management; however, information is scant on the association between spicy food intake and obesity. This study aims to examine the impact of spicy food on quantitative adiposity measures in the Chinese population; a population with a low prevalence of general ob...

Insulin, like leptin, is considered as a lipostatic signal acting at a central level. Aging and age-associated adiposity have been related to the development of leptin resistance in Wistar rats. In the present article, hypothalamic insulin response during aging has been studied in Wistar rats. Thus, the effects of intracerebroventricular infusion of insulin during a week on food intake and body...

We recently demonstrated that in a rodent model of obesity (agouti yellow mice), there is a selective leptin resistance with preservation of the sympathetic actions despite loss of appetite and weight-reducing actions of systemic leptin. Here, we examined whether selective leptin resistance exists in agouti mice during central neural administration of leptin. In agouti obese mice and lean contr...

OBJECTIVE Glucagon receptor antagonists and humanized glucagon antibodies are currently studied as promising therapies for obesity and type II diabetes. Among its variety of actions, glucagon reduces food intake, but the molecular mechanisms mediating this effect as well as glucagon resistance are totally unknown. METHODS Glucagon and adenoviral vectors were administered in specific hypothala...
