Background: Primary hyperparathyroidism (pHPT) is the most prevalent manifestation of multiple endocrine neoplasia type 1 (MEN1). Surgery is the preferred treatment but which type of surgery offers the best chance of cure combined with the lowest risk of postoperative hypoparathyroidism is still uncertain.Aims: Identifying the optimal surgical technique for MEN1 related pHPT. Describing the course of postoperative hypoparathyroidism. To see if a genotype...

The glycoprotein hormone common alpha-subunit (alphaGSU) is an early endocrine marker of pituitary development and is expressed concurrently with the orphan nuclear receptor, steroidogenic factor-1 (SF-1). Our studies have examined the potential role of SF-1 in alphaGSU gene expression using two gonadotroph-derived cell lines as models of the developing pituitary.We investigated the role of SF-1 and its binding site, the gonadotroph-specific element (GSE...

Purpose: Individuals with mood disorders and schizophrenia (SCZ) exhibit altered function of the HPA axis in response to stress. The glucocorticoid receptor (GR) plays an important role in negative feedback regulation of the HPA-axis. There are two protein isoforms, GRα and GRβ, which have activating and blocking activity respectively. In line with aberrant expression of GR mRNA in the brains of depressed, SCZ and bipolar (BD) patients (1), lymphocytes of depressed, ...

Local glucocorticoids action depends on 11β hydroxysteroid dehydrogenase (11β-HSD) enzymes. Adipose tissues mainly express the 11β-HSD1, which activates inactive cortisone. Altered 11β-HSD1 and GLUT4 expressions have been reported in obesity. GLUT4 participates in the genesis and maintenance of insulin resistance/obesity, and could also be involved in the insulin resistant state observed in hypercortisolism. The aim of this study was to investigate the 11&#...

Introduction: Most paediatric medicines have not undergone extensive clinical trials in children and as a necessity are frequently prescribed off-label, a practice which is recognised to be associated with an increased risk of adverse drug reactions (ADRs).Aims: To assess the use of routinely acquired healthcare data to identify medication utilisation and specifically drug discontinuation, as a signal for possible ADR occurrence in children: using orlist...

Introduction: Insulin resistance results from a combination of genetic and environmental factors and it may be considered the primary cause of the development of metabolic disorders, such as type 2 diabetes mellitus. It is characterized by a reduced ability of insulin sensitivity tissues to respond to normal levels of the hormone. In these tissues, glucose transport stimulated by insulin occurs through the glucose transporter 4 and alterations in its expression are related to ...

Lost to follow-up (LTFU) is a frequent problem in chronic diseases not evaluated yet in acromegaly despite the long-term need of medical treatment and complications survey in this disease.Objectives: Evaluation of the prevalence of LTFU patients in a multi-center cohort, characteristics of defaulters and description of their evolution after they have been searched and found.Méthods: Observational multicentric (25 centers study...

Studies have demonstrated that ATP-sensitive potassium channel (KATP) subunits SUR2A (sulfonylurea receptor) and KIR6.2 are involved in glucose uptake into skeletal muscle. It is known that the glucose transporter 4 (GLUT4) expression is highest in oxidative type I fibers, pointing out the important role of oxidative muscles as glucose uptakes. Considering these aspects the aim of this study was to investigate whether KATP channel can influence glucose uptake in oxidative musc...

Introduction: Considering the high capacity of water transport of Na+/glucose cotransporter SGLT1, the aim of this study was to investigate the potential role the SGLT1 in luminal membrane of ductal cells of salivary glands upon the non-stimulated salivary secretion of diabetic rats. The present study also investigates the presence of glucose transporter GLUT1 in salivary glands of rats.Methods: Non-stimulated salivary secretion and SGLT1/GLUT1 protein (...
