Cripsell Professor, Chief of the Division of Endocrinology and Director of the General Clinical Research Center and Henry B Mulholland Professor and Chair, Department of Internal Medicine at the University of Virginia. He is a fellow of the A...

A defect in klotho gene expression in mice leads to a syndrome resembling aging, including a shortened life span, hypogonadism, growth arrest, hypoactivity, skin atrophy, muscle atrophy, hearing loss, premature thymic involution, cognition impairment, motor neuron degeneration, arteriosclerosis, osteopenia, soft tissue calcification, and pulmonary emphysema among others. In contrast, overexpression of the klotho gene extends life span in the mouse. Thus, the k...

Congenital imprinting disorders (IDs) are a group of rare conditions affecting growth, metabolism and development caused by aberrant expression of imprinted genes in a parent-of-origin dependent manner. The internationally recognised IDs are Prader Willi Syndrome (PWS), Angelman Syndrome (AS), Beckwith Wiedemann Syndrome (BWS), Silver Russell Syndrome (SRS), Temple Syndrome (TS14), Pseudohypoparathyroidism (PHP), Transient Neonatal Diabetes Mellitus (TNDM) and Kagami-Ogata Syn...

Introduction/background: Hypothalamic Amenorrhea (HA), or stress-induced anovulation, is one of the most common causes of secondary amenorrhea (1,2) and accounts for the reproductive dysfunction seen in under nutrition, excessive exercise, sever emotional stress and chronic disease. From a teleological standpoint, in the face of nutritional or physical stress, it is adaptive for an organism to allocate energy resources for its own survival rather than the costly process of rep...

The incidence of Alzheimer’s disease (AD) is higher in women than men. Our study aimed to investigate the behavioral, biochemical, and histological changes in lipopolysaccharide (LPS)-induced AD, to study effect of estrogen in AD clarifying the possible involved underlying mechanisms and its modulation by progestsserone. Groups: Female albino rats were divided into control, AD, AD+ovariectomy (OVX), AD+OVX+estrogen replacement and AD+OVX+estrogen+pr...

Introduction: The hCG stimulation test is a useful indicator of functional testicular tissue and may also have a place in treating undescended testes (UDT). However, its utility is limited by the inconsistency in the regimens used. We have looked at the clinical and biochemical response in a group of children with UDT who had a prolonged hCG stimulation as part of their clinical management.Methods: The retrospective review in 17 cases with a median EMS (...

Background: Patients suffering from polycystic ovarian syndrome (PCOS) are warned for arterial disease. We examined the risk of (non)fatal coronary heart disease (CHD) or stroke between PCOS patients and ovulatory, non-PCOS women. Further we assessed the effect of obesity on this riskMethods: We performed a systematic review and meta-analysis of controlled observational studies. Four definitions of PCOS were considered: WHO type II anovulation (1976), NI...

Background: Insulin-like growth factor 1 (IGF1) plays a central role in metabolism and growth regulation. High IGF1 levels are associated with an increased risk of cancer, low IGF1 levels with increased risk for cardiovascular disease. We hypothesized that the relationship between circulating total IGF1 levels and mortality is U-shaped.Methods: We performed a systematic review searching PubMed, EMBASE, Web of Science, Cochrane Library (1985 to September ...

Obesity was considered to be a protective condition against osteoporosis. New studies suggest that visceral obesity is associated with low BMD and a higher risk for fracture. Patients with diabetes mellitus, although they do not have a lower BMD, have a higher fracture risk, probably due to the lower bone turn over.Aim: The aim of the study was to evaluate bone metabolism in connection with hormonal profile in postmenopausal women with metabolic syndrome...

Menopause is a physiological condition associated with an important change in the hormonal status, an adverse lipid profile and cardiovascular risk. Apolipoproteins are proteins that bind to lipids to transport them. Apolipoprotein intestine synthesis is regulated principally by the fat content of the diet, while in the liver by dietary composition, hormones, alcohol intake and lipid lowering drugs. Are they changed due to aging? Do they interfere in the hormonal changes?<...
