Background: The activation of the GHS-R1a receptor by acylated ghrelin (AG) or by synthetic GH secretagogues (GHS), potently stimulates GH release and mediates other neuroendocrine/metabolic effects. Beta-adrenergic receptor agonists negatively influence GH secretion and other metabolic functions. The GH response to AG and GHS is refractory to the inhibitory effect of β2-adrenoceptors activation but no other report has evaluated the interactions between AG and salbutamol ...

Abstract: Obesity results from an imbalance between caloric intake and energy expenditure. Specialized neurons of the hypothalamus coordinately control the integration between feeding and thermogenesis and a defective regulation of these parameters contribute to the progressive accumulation of body fat. Recent studies have revealed that at least part of hypothalamic dysfunction contributing to the development of obesity results from the activation of a local inflammatory respo...

Context and objective: During fasting growth hormone (GH) promotes lipolysis, attenuates glucose oxidation and preserves protein. Previous studies have primarily been conducted in GH deficient patients or during somatostatin-suppression of GH secretion. We aimed to study the impact of the fasting associated increase in GH without concomitant changes in other hormones, by the means of GH receptor (GHR) blockade.Design: Ten healthy young men participated i...

Circadian rhythms in behaviours and gene expression are driven by the autonomously rhythmic cells of the hypothalamic suprachiasmatic nucleus (SCN). In nocturnal rodents, restricting a daily meal to the lights-on phase, leads to entrainment of behaviour and gene expression in many extra-SCN hypothalamic nuclei and peripheral tissues. This anticipatory activity is independent of the SCN and is likely to arise from the activities of multiple hypothalamic centres including the do...

Glucose-dependent insulinotropic polypeptide (GIP) is an incretin hormone secreted by K-cells of proximal small intestine that is secreted postprandial in response to glucose and fat ingestion. Its effect is mediated through a GIP receptor (GIPR) which is widely expressed in different tissues, e.g. pancreatic islets, adipose tissue, skeletal muscle, adrenal cortex, heart, pituitary and in some regions of the brain. However, only the effect of GIP in pancreatic beta-cells is we...

Background: Glucose-dependent insulinotropic polypeptide (GIP) is a gastrointestinal hormone that is secreted in response to food intake. GIP acts on various tissues, including pancreatic ß-cells, via interaction with its G-protein-coupled receptor. Some studies in rodents suggested that GIP directly links overnutrition to obesity. GIP exerts a physiological role on lipid uptake into adipocytes.Objectives: To analyse the effect of GIP-Infusions on c...

Overweight and obese subjects often suffer from hypoglycaemic symptoms due to hyperinsulinemia. This increases subjects’ need to eat excessive amount of food enriched in sugar causing rebound hyperglycaemia which in turn stimulates endogenous insulin release perpetuating a vicious circle that limits weight loss under diet restriction programme. Two previous studies showed that administration of Glucose RapidSpray™ (GRS) in quantity of ~ 0.5 g increases blood glucose ...

Objective: PCOS patients are often characterized by insulin resistance, abdominal obesity, and low-grade inflammation.

Introduction: Hypertension is a major risk factor for several cardiovascular diseases including coronary heart disease. Prehypertension is defined systolic blood pressure (SBP) between 120–139 mmHg and diastolic blood pressure (DBP) 80–89 mmHg. Recent studies have documented an increased risk of cardiovascular disease in persons with prehypertension. In this study, we evaluated association between prehypertension and the metabolic risk markers in over weight and obes...

Background: Hormone replacement therapy (HRT) in post-menopausal women carries an increased risk of cardiovascular disease due to an unfavorable effect on lipid profile. Thus, HRT treatment increases concentrations of very-low-density-lipoprotein-triglycerides (VLDL-TGs) which have been demonstrated to possess atherogenic properties. However, the exact mechanisms whereby VLDL-TG concentrations are increased by estradiol are not fully understood. Estradiol acts on both rapid re...

Recently, low serum adiponectin levels is created as a new risk factor for cardiovascular diseases in climacteric women. Our previous study shows that smoking, serum testosterone levels, blood pressure and BMI have the influence on serum adiponectin levels. Endocannabinoid system plays a role in regulation of food intake and fat accumulation, as well as lipid and carbohydrate metabolism. Menopause transition is related to metabolic disorders (e.g. obesity) and cause the increa...

One of the key actions of insulin is the regulation of glucose and lipid oxidation. Disturbances in substrate oxidation play an important role in the development of insulin resistance.
