Adropin, hormone playing an important role in carbohydrates and lipids metabolism, improves mainly the glucose homeostasis. It could also play a protective role in pathogenesis and development of cardiovascular diseases. The purpose of the study was to assess the adropin concentration and some parameters of nutritional status (BMI, WHtR, BAI, VAI) as well as biochemical parameters (fasting glucose and insulin, and lipid profile). 25 patients (84% of group was women, n...

Visfatin (pre-B cell colonyenhancing factor) is a adipocytokine playing an important role in glucose homeostasis. High concentrations of visfatin are observed in obese people. Previous studies suggest that estimation of visfatin concentration could be a promising tool for predicting obesity or its metabolic consequences. The aim of the study was to evaluate the correlation between visfatin concentration, selected anthropometric parameters (BMI, WHR, BAI, VAI index) and biochem...

Introduction: In recent years the growing rate of newly diagnosed papillary tyroid cancers (PTC) has been observed. Nowadays most of PTC are small (mostly <2cm in diameter) with no unfavourable patomorphological features, although the cases of incompletely resected PTC can still be encountered. Incomplete tumour resection, regardless of the presence of microscopic (R1) or macroscopic (R2) disease, after operation, is considered as a high-risk factor for PTC recurrence/pers...

Introduction: Several investigations proved the presence of receptors for androgens, estrogens and progesterone in vocal folds. The most common endocrine disorder causing alterations in the aforementioned hormones concentrations is polycystic ovary syndrome (PCOS), which, according to several studies, can cause voice changes, especially deepening of its timbre. Over last few years, vocal changes accompanying many different disorders have been a subject of research with the use...

Introduction: Selenium (Se) deficiency is a known risk factor for autoimmune thyroid diseases including Graves’ orbitopathy (GO).Objective: To determine the concentration of Se in serum and to determine the dependency of Se concentration on known markers of disease severity: the TRAB levels and the CAS (clinical activity score) in patients with GO.Material: 64 patients (50 women, 14 men; average age- 54.5 years) with active, m...

Background: Irisin is an adipokine/myokine which could be connected with insulin sensitivity. Polycystic ovary syndrome (PCOS) is characterized by oligo- or anovulation, polycystic ovary, hyperandrogenism and insulin resistance.Objective: The aim of the present study was to determine the relationship between serum irisin concentration and insulin sensitivity (Mffm) as well as the effect of insulin infusion on circulating irisin levels in PCOS ...

Introduction: Radioiodine therapy is considered as a risk factor for the development of Graves’ orbitopathy (GO) de novo or worsening of pre-existing orbitopathy. This risk is estimated in the available literature as up to 15–20%. Steroid cover is considered to eliminated this risk.Objective: The aim of our study was to established the relationship between the occurrence of GO and treatment with radioiodine. And the analysis of the time of appe...

Aim of the study: Medullary thyroid cancer (MTC) occurs as hereditary and sporadic form. Hereditary type is a consequence of RET proto-oncogene germline mutations also somatic RET mutations are detectable in sporadic MTC tumors. There is a significant relation between site of mutation and the cancer phenotype as well as a clinical course of the MEN 2 Syndrome as a consequence of the different transforming potential of the RET gene mutations. The aim ...

Papillary thyroid cancer (PTC) is well known family occurring cancer disease. It is estimated, that ~5% of differentiated thyroid cancers (where PTC is the most frequent) are hereditary. Susceptibility genes are poorly known, however, recently some SNPs located on chromosome 9 in FOXE1 locus (rs965513) and on chromosome 14 (rs944289) close to NKX2-1 locus have been confirmed to be associated with PTC in different populations.The aim of our study was to a...

Objectives: Recent studies on BRAFV600E mutation, known as initiating event in papillary thyroid carcinoma (PTC) and related to more aggressive clinical course of the disease, revealed its significant influence on gene expression profile suggesting that BRAF(+)PTCs represent a molecular subtype of PTC. However, the human material disables distinction of possible molecular causes of cancer from its effects, unlike the mouse model. The main goal of our project was to find genes ...
