Polycystic ovary syndrome (PCOS) is considered as a risk factor for diabetes type 2 (DM2), it is often associated with obesity, β-cell dysfunction or insulin resistance. Genetic factors underlying the association of PCOS with DM2 is unknown. Recent human genetic studies have revealed that transcription factor 7-like (TCF7L2) polymorphisms are associated with DM2 through modulation of β-cell function.The aim of this study was to test if <...

Background and aims: The fat mass and obesity associated gene (FTO) was identified as a gene with strong obesity related traits nevertheless the exact mechanism is still unknown. Our aim was to study the possible effects of FTO risk haplotype on anthropometric data and metabolic and hormonal parameters in lean women (to eliminate the influence of BMI) and to evaluate the effect of hormone contraception (HC).Materials and methods: The SNPs r...

Melanocortin-4 receptor (MC4R) gene is expressed in the brain and has been implicated in mediating most of the effects of melanocortin on food intake and energy expenditure. Common variants of MC4R gene are associated with fat mass, weight, risk of obesity and insulin resistance in several populations.We investigated if rs12970134 A/G is associated with obesity and studied its possible metabolic effects.Polymorphism was assesed by ...

Context: The cyclical effects of hormones during the menstrual cycle (MC) are responsible for driving ovulation. The information about roles of adipokines within the scope of MC are not definite. Leptin plays a role in sexual function and regulating the onset of puberty. Thin girls often fail to ovulate or release an egg from an ovary during menstruation cycles. Leptin also acts on specific receptors in the hypothalamus to inhibit appetite. Levels of leptin are increased in wo...

Background and aims: Neuroactive steroids and their metabolites play an important regulatory role in the nervous system affecting the neuronal plasticity, stress response, learning, and memory. The aim of the study was to compare the steroid metabolome in AD patients and controls.Materials and methods: The study comprised of 48 AD patients (30 women and 18 men; age 73.8±9.54 years) and 33 matched controls (22 women and 11 men; age 68.2±5.94 yea...
