Anti-Müllerian hormone (AMH) is a homodimeric glycoprotein, a member of the transforming growth factor-β superfamily. Over the last decade, a large number of studies examining the multiple roles of AMH have been published. AMH levels accurately reflect the ovarian follicular reserve and could, therefore …

Adiponectin is a white and brown adipose tissue hormone, also known as gelatin-binding protein-28 (GBP28), AdipoQ, adipocyte complement-related protein (ACRP30), or apM1. Adiponectin circulates in the bloodstream in trimeric, hexameric, and high-molecular-mass species, while different forms of adiponectin …

Chronic stress represents a prolonged state of dyshomeostasis caused by intense and frequently imposed stressors. Obesity constitutes a chronic dysmetabolic state, leading progressively to a spectrum of metabolic complications, such as diabetes, dyslipidemia, hypertension and cardiovascular disease. Α growing body of evidence supports the existence of significant interactions between stress and obesity …

Chronic stress can affect human health through a myriad of behavioral and biochemical pathways. Τhis review focuses on some key hormonal and metabolic pathways that appear important today. In modern society, we are faced with excessive psychological stress, as well as an epidemic of overeating, and the two together appear to have synergistic effects …

Serum-and-glucocorticoid-inducible-kinase-1 (SGK1) is under regulation of several hormones, mediators and cell stressors. More specifically, SGK1 expression is particularly sensitive to glucocorticoids, mineralocorticoids, and TGFβ. Moreover, SGK1 expression is exquisitely sensitive to hypertonicity, hyperglycemia, and ischemia …

Ghrelin, an orexigenic protein with a unique lipid chain modification, is considered to be an important gut-brain signal for appetite control and energy balance. The ghrelin receptor, growth-hormone secretagogue receptor type 1a, is able to bind acylated ghrelin. The first recognised effect of ghrelin was the induction of growth hormone …

Obesity and type 2 diabetes are metabolic diseases that have reached epidemic proportions worldwide. Although their etiology is complex, both result from interplay between behaviour, environment and genetic factors. Within ambient determinants, human overall gut bacteria have been identified as a crucial mediator …

Obesity, the most common metabolic disorder, concerns, among others, women of reproductive age and, when it occurs before or during pregnancy, constitutes a major risk factor for both maternal and fetal complications. The complications of obesity in a prospective mother include subfertility, miscarriage, thrombo-embolism, hypertensive disorders …

Obesity is one of the most frequently encountered medical problems of our time. Among the complications of this pathologic entity, renal disease is an important issue and its pathophysiologic mechanisms are a challenge for the physician, since a variety of etiologic factors are implicated in its genesis. For example, hypertension, hyperlipidemia and insulin resistance …

OBJECTIVE: The combination of 32 mg naltrexone and 360 mg bupropion prolonged release (NB32) was recently approved by both the food and drug administration (FDA) and the European medicines agency (EMA) as an adjunct to a comprehensive lifestyle intervention to achieve weight loss …

OBJECTIVE: Ghrelin and leptin levels are influenced by body fat (BF%), pubertal stage and possibly insulin resistance (IR). The aim of our study was: 1) To compare fasting ghrelin and leptin levels between obese and non-obese, adolescents, 2) to investigate possible correlations of these hormones with BF %, as well as IR…

OBJECTIVE: While the US today has the highest rates worldwide of obesity, Europe, and particularly Southern Europe, is catching up fast. The aim of this study was to report the prevalence of obesity in Greek children, aged 1-12 years. DESIGN: A systematic review—including all studies published in English and Greek …

Polycystic Ovary Syndrome is a heterogenous syndrome of unknown causation commonly associated with obesity. Τhe particular timing of the onset of obesity may be important, since the earlier the onset of obesity the greater the severity of the metabolic and hormonal aberrations …

OBJECTIVE: Obesity and diabetes are considered risk factors for Renal Cell Carcinoma (RCC). We aimed to explore whether insulin resistance (IR) plays an independent role in the development of RCC. DESIGN: In a hospital-based case-control study, we analyzed serum glucose …

OBJECTIVE: Leptin is primarily produced in adipose tissue and appears to play a modulatory role between metabolism and immunity. Given that obesity, a state of chronic inflammation, is an established risk factor for Renal Cell Carcinoma (RCC), we investigated the association between plasma leptin levels and RCC risk …
