An association of the single nucleotide polymorphism (SNP) in the promoter gene that codify for 17b-HSD5 enzyme (71A>G) with polycystic ovary syndrome (PCOS) has been suggested in previous studies. Given the role of 17b-HSD5 in androgenic metabolism producing testosterone from precursors, the aim of this study was to assess whether non-obese PCOS women with the variant allele G have different response on hirsutism and on hormonal and metabolic variables to oral contracepti...

Myostatin is expressed predominantly in skeletal muscle and at significantly lower levels in adipose tissue. The loss of myostatin by gene disruption prevents an age-related increase in adipose tissue mass and partially attenuates the obese and diabetic phenotypes. Inhibition of myostatin signaling could be useful to prevent and/or treat obesity and diabetes. Male OLETF and LETO rats as non-diabetic controls were treated with or without ALA (100 mg/kg per day) and/or insulin (...

Ghrelin receptor GHSR1α is expressed in hypothalamo–pituitary–gonadal tissues. Ghrelin reduces GnRH secretion in pre-pubertal period and concentrations of ghrelin are positively correlated with testosterone at adulthood. Nevertheless, the role of ghrelin in affecting pituitary and gonadal functions during normal pubertal development remains elusive. A possible correlation between ghrelin and LH, FSH, testosterone and inhibin B was examined in boys (n=55...

The G protein coupled receptor of obestatin GPR39 is expressed in pituitary and gonads, indicating its possible role in regulation of pituitary and testicular function. The present study examined a possible association of obestatin with LH, FSH, testosterone, and inhibin B at puberty. Blood samples were collected from 10 to 20 years old boys (n=557) and concentrations of obestatin, LH, FSH, testosterone, and inhibib B were determined using specific ELISA. Data were an...

Leptin, a key metabolic signal controlling both energy intake and energy reserves, informs the brain about energy stores of the body to initiate reproductive processes at puberty. Thyroid hormones are important determinant of overall energy expenditure, basal metabolic rate and thermogenesis. The present study examined the relationship between leptin and thyroxine (T4) and triiodothyronine (T3) in boys (n=540) between the age of 1 and 20 years. B...

Background: Hypertension is the most important chronic condition leading to cardiovascular complications in India. Lack of awareness and epidemiological data is the reason for inertia for primordial, primary and secondary prevention. Education, region epidemiological mapping and early screening and intervention can help benefit the population in terms of cardiovascular morbidity and mortality.Aims & Objectives: To gather, analyze and intervene a larg...

Ghrelin, a putative signal of insufficient energy stores, increases in fasting states, decreases postprandially, and acts as a potent appetite stimulant increasing food intake. Obestatin affects appetite, food preferences to increase daily caloric intake and weight gain. Leptin regulates body fat mass, food intake and energy expenditure. Triiodothyronine (T3) is a determinant of adiposity, thermogenesis, glucose and lipid metabolism, appetite, food intake, and the o...

Background: Residual C-peptide (CP) secretion has been associated with better glycemic control in patients with type 1 diabetes (T1D).Aim: To evaluate how residual fasting CP (fCP) secretion impacts glycemic control in T1D and to identify possible confounding factors.Methods: A retrospective analysis of adult patients with T1D followed in our department that had their fCP and glucose levels obtained on the same blood sample during ...

Congenital adrenal hyperplasia (CAH), caused by lack of 21-hydroxylase, impairs cortisol secretion, which increases ACTH release that results in hyperplasia of adrenal glands and increased secretion of adrenal androgens. Elevated androgen concentration leads to increased skeletal maturation, early pubertal development and diminished pubertal growth. Treatment with glucocorticoids averts early puberty but may abruptly slow down growth. The effect of exogenous glucocorticoids on...

Background: Type 3 neuroendocrine tumors of the stomach (type 3 NETV) are very rare subtypes of NETV with poor prognosis, not fully understood biology and not well investigated diagnostic and therapeutic procedures. The aim of the study was to analyze tumor biology and the outcome of differentiated treatment in patients with type 3 neuroendocrine tumors of the stomach.Methods: A prospective 10 years follow up of five patients with type 3 NETV treated in ...
