Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by increased risk of atherosclerosis. A higher prevalence of PCOS in T1DM patients has been reported. Brachial artery flow-mediated dilatation (FMD) and intima media thickness of common carotid artery (IMT) are used to detect an early endothelial dysfunction.The aim of our study was to examine IMT and FMD in T1DM women with PCOS. We also estimated the relation of IMT and FMD to c...

Introduction: The prevalence of polycystic ovary syndrome (PCOS) is increased in women with type 1 diabetes (T1DM) in comparison to the general population. It has been suggested that exogenous insulin administered to T1DM women in supraphysiological doses could act as co-gonadotropin and lead to disturbances observed in PCOS.Aim: The aim of this study was to evaluate the phenotypic characteristic and differences between diabetic women with PCOS (T1DM+PCO...

Introduction: Brain derived neurotrophic factor (BDNF) is a neurotrophin which plays a role in neuronal growth and differentiation. Decreased level of BDNF is supposed to play a role in the pathogenesis of the neurodegenerative diseases. Recent data indicate that BDNF could be also involved in angiogenesis. Several lines of evidence support the role of BDNF in glucose metabolism. The decreased level of BDNF are observed in obesity and type 2 diabetes mellitus. Polycystic ovary...

Introduction: Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by an increased risk of cardiovascular complications. The higher prevalence of PCOS in T1DM was reported and thus T1DM women with PCOS exhibit a higher risk of cardiovascular diseases. Soluble E-selectin (sE-selectin) and intercellular adhesion cell molecule-1 (sICAM-1) are considered as an early markers of atherosclerosis.Aim: We aimed to evaluate plasma levels of ...

Introduction: Mechanism of pathogenesis of pituitary adenomas is still unknown. Gene expression differences in pituitary cells of different origin are not extensively described. Identification of genes specific for pituitary adenomas should enable better understanding of differences in their response to therapy, especially to radiotherapy.Aim: The aim of our study was to evaluate the correlation of coexpression of distinct pituitary adenoma genes based o...

Introduction: The activating BRAFV600E is the most common genetic alteration in PTC. There is a common belief that it can correlate with a more aggressive clinical course. The mutation of the CHEK2 gene impairs the repair processes of the damaged DNA. It can be expected that the coexistence of both mutations can be related to a worse clinical course.Aim: To assess the prevalence of the coexistence of the CHEK2 and BRAFV600E mutation...

Introduction: Still there is a discussion about the importance of diagnostic and prognostic relevance BRAFV600E mutation. The wide range of BRAFV600E mutation frequency (40–80%) doesn’t facilitate this task. Population diversity and genotyping methodology are suspected sources of differences seen in the mutation frequencies detected by different studies. The aim of this study was to assess the prevalence BRAF V600...

Introduction: BRAFV600E mutation constitutes 98–99% of all detected mutation in thyroid carcinoma. The remaining 2% are BRAF mutations detected in the vicinity of codon V600. Due to the low incidence not much is known about their importance for the development of papillary thyroid carcinoma (PTC). In addition, some of these mutations co-occur with the mutation BRAFV600E.Methods/design: The study prese...

Introduction: Polycystic ovary syndrome (PCOS) is associated with an increased risk of insulin resistance. The involvement of microRNAs, small, non-coding molecules, in regulation of metabolic processes has been investigated. The role of miR-27a and miR-320 in regulation of glucose metabolism is documented. The aim of the study was to assess the level of circulating miR-27a and miR-320 in PCOS patients and to investigate its relationship with glucose metabolism.<p class="a...

Introduction: Chronic inflammation is an important factor in type 2 diabetes and cardiovascular diseases development. Studies demonstrate that body fat, estimated by anthropometric indicators, correlates with inflammation indicators in chronic diseases. Ipso facto, it seems reasonable to suppose, that there would also be a correlation between anthropometric parameters and both, old and new inflammation indicators in patients with non-functioning adrenal incidentalomas.<p c...
