Introduction: Vasovagal syncope (VVS) is a transient loss of conscioussness due to hypoperfusion of the brain caused by vasodepressoric and/or cardioinhibitory reflex. In the pathogenesis, a dysregulation of autonomic nervous system is playing an important role. There is a growing evidence about more complex neurohumoral background of VVS. Neuropeptide Y (NPY) is hormone involved in the regulation of blood pressure with potent vasoconstriction effect. Moreover, NPY is also a c...

Bisphenol A (BPA) is an environmental estrogen found in plastic material such as bottles, food package, dental material, etc. It is known to have many negative effects on human health and its exposure is associated with endocrine disorders including polycystic ovary syndrome (PCOS). Some studies found significantly higher serum and urinary levels of BPA in PCOS women, however its association with steroid hormones is still controversial.Aim: The aim of th...

Objectives: Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in women. Its increasing prevalence is probably related to environmental estrogens exposure, such as bisphenol A (BPA). BPA is considered to play an important role in the ethiopathogenesis of PCOS and can be responsible for various clinical symptoms. Aim of the study was to compare the levels of urinary BPA between PCOS women and healthy controls and to assess the relationship of BPA to sex...

Objectives: Adenosine is a purinergic mediator involved in the regulation of many physiological and pathological processes. It acts as neurotransmitter in the central and autonomic nervous system, where it counterbalanaces sympathetic activity. Adenosine is produced by majority of human cellsexerting autocrine, paracrine as well as systemic effects. Due toits vasodilatatory and negative inotropic effects it seems to play a role in ethiopathogenesis of orthostatic intolerance, ...

Background: There is evidence that polycystic ovary syndrome (PCOS) is commonly associated with higher cardiometabolic risk. Aim of the study was to compare various sex streoids in PCOS women with overweight or obesity (BMI >27) and those with lower BMI. Second aim of the study was to determine the relationship of various sexual setroids to cardiovascular risk in PCOS women.Subjects and methods: Study included 64 Caucasian women with PCOS. F...

Objectives: There is a growing evidence suggesting an impact of endocrine distrupting chemicals, including bisphenol A (BPA) on human reproduction. Insulin growth factors (IGF) play signifcant role inhuman reproduction. However the relationship between BPA and IGF system is unknown. Aim of the pilot study was to assessthe relationship between urinary BPA (U-BPA) and insulin growth factors (IGF-1, IGF-2, IGFBP 3) as well as metabolic parametersin PCOS women.<p class="a...

Objectives: Insulin-like growth factors 1 and 2 (IGF1 and IGF2) are widely expressed mitogenic peptides playing a role in the fetal developement and differentiation. Evidence suggest their possible involvement in the pathogenesis of metabolic syndrome and probably in polycystic ovary syndrome (PCOS).Aim: Aim of the study was to assess the relationship of serum IGF1, IGF2 and IGF binding protein 3 (IGFBP3) levels to steroid hormones and metabolic paramete...
