Background: The phytoestrogen resveratrol found in grapes and other plants has attracted considerable interest due to its proposed ability to extend lifespan, attenuate the development of metabolic syndrome in obese subjects and protect against cardiovascular disease. Among other functions resveratrol has been reported to affect the endocrine system. Self-medication with high pharmacological doses of this polyphenol with the aim to improve metabolic parameters and health canno...

Background: Obesity and metabolic syndrome related co-morbidities are increasingly recognized in children. Reproduction is an important target of obesity complications, including adverse effects on spermatogenesis and steroidogenesis in males. Adipocytokines are key players in various complications of obesity.Objective and hypotheses: The aim was to study the potential effects of adipocytokines on Sertoli cell function and possibly link the findings to t...

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism. However, the source of androgens is not entirely clear.Objectives and hypotheses: Our objective was to find out if adipose tissue (AT) is a site of steroid production during childhood and adolescence, and if this source could add to hyperandrogenism in obese females.Methods: Parametrial and inguinal adipose tissue was collected and...

Background: Childhood obesity is a global health problem and co-morbidities develop already during childhood and adolescence. Male obesity impacts negatively on reproductive function. Testosterone is decreased, sperm quality reduced, and the physical and molecular structure of germ cells altered in obese males. However, less is known about the role of prepubertal obesity on future reproductive function. We therefore explored Leydig cell function and reproductive potential in a...

It is generally accepted that androgens produced by fetal Leydig cells (FLC) control proper masculinization of the male external genitalia. Here, we hypothesized that the human genital tubercle (GT) has potential to synthesize androgens independently of FLC at early pregnancy. We observed that human GT of both genders have capacity to synthesize steroids of the Δ4, Δ5 and alternative pathway of DHT synthesis including the androgen itself. The presence of steroids in ...

Background: Insulin-like factor 5 (INSL5), a member of the insulin superfamily, is expressed in the colorectum and hypothalamus. INSL5 levels are elevated by prolonged calorie restriction and declined with feeding, suggesting that it might be an orexigenic hormone.Objectives and hypotheses: Our aim was to explore the relationship between INSL5 and different metabolic parameters in lean and obese subjects and to identify possible links between INSL5 and t...

Background: Steroid hormones produced by the human fetal adrenals (HFA) are suggested to regulate intrauterine homeostasis and the maturation of certain fetal organs necessary for extrauterine life. Appropriate development and hormonal function of the HFA therefore are critical for normal fetal maturation and survival. Little is known about the possible relationship between the expression of steroidogenic enzymes and corresponding transcription factors in the HFA in vivo</...

Actuality: Standard methods for determining the compensation of the disease don't always reliably reflect the level of the glycemic control of the patient, which leads to decompensation diabetes and reduce the quality and duration of life for patients. Evaluation of glycemic variability indices allows the physicians to predict the risk of developing life-threatening conditions and compensate the diabetesAim: To condu...

Background: Cytosine-guanine(CpGs) sites in molecules identified as methylated or unmethylated; the combination of them in the genetic sequence of an individual includes a methylation haplotype (methyl-haplotype) for a specific locus. The insulin gene promoter(IGP) is highly regulated by methylation mechanisms, which lead to alteration of gene expression.Aim: To identify IGPmethyl-haplotypes among children/adolescents wi...

Introduction: The selection of the insulin catheter length for pump T1D users is based mainly on age and though different sites for insertion have been suggested, it is not clear what the ideal site is according to each person’s body type and subcutaneous fat.Aid: Aid of the study is to identify the proper sites for insulin catheter insertion according to subcutaneous fat and anthropometric characteristics.Methods: Study group...
