Extracellular proteolytic cleavage of insulin receptor (IR) and the generation of soluble insulin receptor (sIR) is a response of the liver and fat associated with physiological conditions and metabolic alterations mainly related to hyperinsulinemia. However, cleavage of this receptor has not been analyzed in skeletal muscle, a central tissue in insulin-mediated glucose homeostasis. This study aimed to analyze the insulin receptor subunits in the gastrocnemius and soleus muscl...

Background and aims: Polycystic ovary syndrome (PCOS) is characterized by phenotypic heterogeneity and a wide variety of consequences. About half of PCOS women are overweight or obese and their obesity may be a contributing factor to PCOS pathogenesis. The aim of this study was to evaluate if PCOS alone affects the patients’ quality of life and to what extent obesity contributes to worsen this disease.Methods and results: In total, 200 women with PC...

Metabolic syndrome (MS) is a group of signs that increase the risk of developing cardiovascular diseases and type 2 diabetes mellitus (DM2). MS includes at least 3 of these signs: central obesity, dyslipidemia, hypertension, fasting glucose disorders, and insulin resistance. The consumption of sugar drinks, a high-calorie diet, a sedentary lifestyle, and environmental pollutants such as arsenic increase the risk of developing MS. Arsenic affects beta-cell function and insulin ...

Introduction: Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) is an innovative method for the detection of primary tumours or metastases of thyroid cancer; however, recurrence or metastases of medullary thyroid carcinoma (MTC) are still difficult to detect.Aim: The objective of this study was to evaluate the clinical use of 18F-FDG PET in patients with MTC.Patients and methods: We enr...

Background: Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is a new method employed in the management of differentiated thyroid cancer (DTC). The integrated FDG-PET plus computed tomography (PET/CT) fusion imaging system seems able to provide some additional advantages over PET alone, mainly related to a better anatomical localisation of the hypermetabolic metastatic lesions. The influence of serum TSH levels on 18F-FDG uptake by recurrences o...

Introduction: Papillary thyroid micro-carcinoma (PTMC) is a well-differentiated thyroid cancer ≤10 mm in diameter. The recent higher prevalence of PTMC is due to the frequent detection of micro-carcinomas as an incidental finding in surgical specimens, but especially during routine imaging of the neck with highly sensitive techniques.Aim: To review the clinical course of PTMC so to reach its optimal management by adapting therapy and follow-up sche...
