Metabolic syndrome is risk factor for cardiovascular event. According recommendation of NCEP ATP III, the major component of metabolic syndrome is waist circumference up to 94 cm in male and 80 cm in female, and two of following disturbances: fasting glucose up to 5.6 mmol/l, HDL below 0.9 in male and 1.3 in female, triglycerides up to 1.7 mmol/l and BP up to 135/80 mmHg.We have analyzed the influence of low calorie diet (1200–1500 kcal/day) with in...

Background: Metabolic syndrome (MetS) is a clustering of metabolic and cardiovascular risk factors, with insulin resistance being one of the main components. In male, MetS is also associated to hypogonadotropic hypogonadism. Lifestyle modifications (e.g. physical activity) could prevent or considerably reduce MetS progression, however the ability to perform physical activity is often impaired in MetS subjects.Aim: Considering the known trophic role of T ...

Aim of the study: To evaluate efficacy and safety of ultrasound-guided percutaneous laser ablation (PLA) on benign thyroid nodule size reduction, thyroid function and autoimmunity.Methodology: This study was approved by local institutional review committee. All data are mean±S.D. Two hundred and ninety-eight euthyroid outpatients (F=241, M=57; age 50.7±12.0 years) with a benign thyroid nodule (volume 23.1±21.3 ml) causing ei...

Fibro-adipogenic progenitors (FAPs), a muscle-resident stem cell population, have recently emerged as important actors of muscle regeneration by interacting with myogenic progenitors (MPs) to promote the formation of new muscle fibers. However, in pathological condition, as muscle dystrophies, this coordinated response is lost and then an accumulation of FAPs is observed. In particular, in a mouse model of Duchenne muscle dystrophy (mdx), the accumulation of a specific subpopu...

Simultaneous knockout of the neuroendocrine marker genes Ptprn and Ptprn2, which encode the protein tyrosine phosphatase receptors N and N2, respectively, causes infertility of female mice while males are fertile. To clarify the mechanism of sex-specific roles of Ptprn and Ptprn2 in mice reproduction, we analyzed the effects of their double knockout (DKO) on the hypothalamic-pituitary-gonadal axis. In DKO females, a delay in puberty and lack...

Introduction: The corpus callosum is the most important of the interhemispheric commissures, its fibers called callosal radiations have a transverse direction. They connect different points of the neocortex. The corpus callosum represents the neopallial commissure; it has indeed a phylogenetic development modeled on that of the neocortex. Hypoplasia of the corpus callosum is included in a rare polymalformative syndrome characterized by agenesis of the corpus callosum (CC), dis...

Studies conducted using knockout mouse model revealed that defects of PROKR2 affect the correct ontogeny of GnRH neurons and, by consequence, neuroendocrine control of reproduction. Nevertheless its exact role during these processes and in the pathogenesis of congenital hypogonadotropic hypogonadism (CHH) remains elusive due to the phenotypic differences observed between mouse and human. Zebrafish (ZF) has emerged in the last ten years as a reliable model organism for studying...

SSTR2 is one of the main pharmacological target for GH-secreting pituitary adenomas treatment and the cytoskeletal protein FLNA plays an important role in tumor responsiveness by regulating SSTR2 expression and signaling. Single-Molecule Imaging was used to investigate the spatial distribution of FLNA-SSTR2 at the plasma membrane level and the involvement of FLNA in SSTR2 mobility, receptor clustering organization/internalization. This method is based on labeling SNAP/CLIP-tag...

Polycystic ovary syndrome (PCOS) is the most common cause of infertility in reproductive aged women affecting ~5–10% of women of reproductive age worldwide. PCOS patients are characterized by infertility disorders, obesity, insulin resistance and hyperandrogenemia that persists during pregnancy. This finding allowed to suggest the hypothesis that this intrauterine environment could affect the fetus, reprogramming the insulin sensitivity of the offspring. We have developed...

Introduction: Lipid storage myopathy (LSM) is characterized by increased lipid droplets in muscle fibers. Primary carnitine deficiency is the most frequent cause of LSM, clinical presentation ranging from asymptomatic to progressive muscle weakness or cardiomyopathy, carnitine supplementation being effective with remission of symptoms.Case report: In February 2007 R.A. born in 1996 presented progressive muscle weakness with elevated muscular enzymes (LDH...
