Filter by:The study aims to explore the effects of hormonal fluctuations throughout the menstrual cycle on social media use, brain architecture, neural reward processing and reward behavior, and affective status in adolescent girls. Additionally, it strives to compare the effects of exogenous and endogenous hormones on the above-mentioned aspects. For this purpose, the investigators will compare two main groups in the study: 1. Naturally cycling adolescent girls, 2. Adolescent girls using combined oral contraceptives. This study will combine self-report data via questionnaires, ecological data via Ecological Momentary Assessment (EMA), endocrine data via blood collection, and neural data via fMRI assessment to enhance the understanding of the neurobiological mechanisms underlying social media use in adolescent girls. Furthermore, it seeks to elucidate whether there are vulnerable periods throughout the menstrual cycle when adolescent girls are especially prone to dysfunctional social media use and help to design more specific interventions as well as therapy.
The goal of this clinical trial is to test effect of menstrual cycle (MC) on growth factors of platelet rich fibrin (PRF) in health condition. The main questions it aims to answer are: question 1: Does MC have an effect on growth factors in PRF? question 2: In which menstrual phase are growth factors higher? question 3:Does the change in the number of blood cells in the menstrual cycle have an effect on PRF? Participants will describe the main tasks participants will be asked to do.
High rate of injuries detected during certain periods of menstrual cycle, raised the suggestion of the effecacy of the female sex hormones on soft tissue and neuromuscular control with subsequent deterioration of postural stability and high injury prevalence in post pubertal females so the aim of the present study is to investigate the effect of female sex hormones on postural stability in post pubertal females.
