The A-ZIP/F-1 transgenic mouse is a model of lipoatrophic diabetes with severe insulin resistance, hyperglycemia and hyperlipidemia. Recently, a regulatory role of adipose tissue on adrenal gland function and blood pressure has been suggested. To further explore the importance of adipose tissue in the regulation of adrenal function and blood pressure, we studied this mouse model of lipodystrophy. A-ZIP/F-1 mice exhibit significantly elevated systolic and diastolic blood pressu...

Neural cells are isolated from forebrain of 14.5 days old mouse embryos. In selective conditions these cells cluster forming sphere-like structures – neurospheres (NSCs). NSCs are heterogeneous structures containing only 2–5% of stem cells and progenitors being reportedly capable to transdifferentiate. Initially, aim of this study is to establish optimal culture conditions prior to investigation of transdifferentiation capacity of transplanted NSCs in kidney and adre...

Intramuscular lipids, including ceramide, might be responsible for the development of insulin resistance. Insulin action is also inversely associated with circulating proinflammatory cytokines, like interleukin (IL)-18 and positively related to antiinflammatory factors, like adiponectin and IL-10. The aim of the present study was to estimate the relationships between serum adiponectin, IL-10 and IL-18 concentrations and muscle lipid fractions in healthy humans.<p class="ab...

Poland was considered as a mild-to-moderate iodine deficiency area according to results of a nation-wide survey conducted in early 1990-ties. The obligatory iodine prophylaxis program based on iodization of house-hold salt (30 mg of iodide/1 kg of salt) was therefore introduced in 1997.The aim of the study was to assess the real impact of the Polish iodine prophylaxis model on thyroid volume in schoolchildren.Material and methods: ...

Objective: Serum TSH and thyroid hormone (TH) levels are routinely used as main measures of thyroid function. While these are highly valuable markers, it is becoming more evident that under specific conditions, their predictive power for tissue TH status is limited due to the highly complex nature of tissue-specific TH signaling. This led to a high demand for human tissue TH action markers that could allow the characterization of tissue TH economy. Therefore, our goal was to d...

Background: Advanced glycation end products (AGEs) are heterogenous group of irreversible chemical moieties originated from non-enzymatic glycation and oxidation of proteins, nucleic acids, and lipids. The engagement of AGEs with their chief cellular receptor (RAGE) activates signaling pathways contributing to the progression of chronic diseases like autoimmune thyroiditis, type 2 diabetes mellitus and its complications. Soluble RAGE (sRAGE) prevents AGE-RAGE interaction in a ...

Introduction: Idiopathic granulomatous hypophysitis (IGH) is a rare inflammatory disease that may present with radiological changes in the pituitary gland. Diagnosis with non-specific syndromes becomes challenging. Secondary causes of granulomatous hypophysitis include tuberculosis, sarcoidosis, syphilis, Langerhans cell histiocytosis, GPA, and Rathke’s cleft cyst rupture. GPA is a multisystem disease, characterized by necrotizing small-vessel vasculitis, mostly affecting...

The most effective conventional treatment for differentiated thyroid cancer (DTC) still remains total thyroidectomy with subsequent adjuvant therapy with radioiodine ablation (RAI). In case of unsuccessful RAI treatment, an alternative method is the tyrosine kinase inhibitor therapy. However, its usage is related to many side effects and is not well tolerated by patients. Despite the great progress in the clinical management of patients with DTC, the lack of alternative therap...

Background: Despite increased awareness among cardiologists about the risk of amiodarone’s significant side effects, it is still a commonly used antiarrhythmic drug. Amiodarone may induced easy for management hypothyroidism which affect even 25% of patients or less frequent thyrotoxicosis (AIT) which causes a challenge for clinicians. Type 1 of AIT occurs on the basis of pre-existing thyroid diseases such as nodular goiter or latent Graves’ disease, type 2 results fr...

Introduction: A number of studies indicate the presence of a thyroid-gut axis and the important influence of the gut microbiota on thyroid function. As prebiotics, probiotics and synbiotics show therapeutic potential in the treatment of intestinal dysbiosis, we aimed to evaluate the efficacy of their supplementation in patients with primary hypothyroidism.Material and methods: We searched electronic databases (Ovid MEDLINE, Embase, CENTRAL), registers of...
