The increasing prevalence of obesity and associated comorbidities worldwide is a major problem for national health care systems. For this reason, it is of importance to gain knew knowledge about the central regulation of body weight and to identify factors which are leading to an increased individual risk to gain weight. Despite large genome weight associations studies and related genetic risk scores, the regulation of inter-individual body weight variability remains elusive. ...

Background: Aromatase (CYP19A1) a member of cytochrome P450 protein family is a major steroid metabolizing enzyme which converts androgens to estrogens. Mutations in aromatase can lead to autosomal recessive aromatase deficiency. An R192H mutation in CYP19A1 described earlier caused severe phenotype of aromatase deficiency with regressive virilization of the 46,XX new-born, but without signs of androgen excess during pregnancy. Computational studies suggested that R192H disrup...

Aims: The golden standard to characterize pubertal maturation is the analysis of steroid hormones in the blood. The aim of the investigation was to assess whether the analysis of salivary steroids is similarly able to characterize male pubertal development.Methods: The investigation included 165 normal boys (mean age 12.7±2.8 years, mean body mass index 19.6±4.2 kg/m2). Pubic hair stages were stratified by Tanner and testicular volum...
