Binaural Beat Music, Virtual Reality, and Hormones in Childbirth

This study aims to investigate the effects of Binaural Beats-supported music and virtual reality experience on the levels of oxytocin, prolactin, catecholamine, endorphin, prostaglandin E and cortisol, which are hormones that play an active role in birth, using the Elisa method. Additionally, the study will examine the effects of virtual reality experience and Binaural Beats-supported music during labor on labor pain and some birth outcomes (such as the presence of an episiotomy, the onset of labor, the duration of labor, and the newborn Apgar score).The randomized controlled study will consist of three groups: a virtual reality group, a Binaural Beats-supported music group, and a control group. The research will be completed with a total of 90 people, with 30 people in each group. The research will be conducted at the Maternity Ward of Istanbul Gaziosmanpaşa Training and Research Hospital. Ethics committee approval has been received for the research. Data collection has not yet begun. An application has been made to the hospital administration for institutional permission. The research will begin once the permissions are received.

Impact of Training Load on the Gut miCrobiome And Its Relation to exeRcise Performance, mUscle Phenotype, and markerS of Overreaching in Healthy Men

The goal of this study is to learn how different amounts of supervised indoor cycling training change gut health (gut bacteria, the substances gut bacteria make, and the gut barrier integrity), and how these changes relate to changes in fitness, muscle health, and signs of doing too much training (a state called 'overreaching'). The study includes healthy, recreationally active men aged 18 to 45 years. The primary questions, for which the study is powered (sufficient participants included), are: 1. Does moderate load training change blood and faecal levels of butyrate (a short-chain fatty acid made by gut bacteria) after eight weeks compared with a control group? 2. Compared to moderate load training, do higher training loads lead to different responses in blood and faecal levels of butyrate? Researchers will compare: * A control group that does not complete structured training; * A moderate-load training group that completes eight weeks of supervised cycling (4x/week); * A high-load training group that completes four weeks of moderate-load training followed by four weeks of higher training load (twice the number of training sessions). Participants will: * Be randomly assigned to one of the three groups; * Complete 8 weeks of supervised indoor cycling sessions if assigned to a training group; * Complete four study assessment periods (baseline, after week four, after week eight, and after a short taper (rest period); * Provide blood, stool, skeletal muscle, urine, saliva, and breath samples during the assessment periods; * Complete fitness and performance tests and questionnaires during the assessment periods.

Amylin-Induced Migraine Attacks Without Aura

Pramlintide is a peptide analogue of human amylin which is a vasoactive signaling molecule involved in the pathogenesis of migraine. This study investigates whether pramlintide induces migraine attacks without aura in people with migraine without aura.

Hypersensitivity to Amylin in Post-Traumatic Headache

Pramlintide is a peptide analogue of human amylin which is a vasoactive substance involved in the pathogenesis of headache. This study investigates whether pramlintide induces migraine-like headache in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).

Decision-making and Food Intake

The study will investigate how the expectation of food availability impacts the response to food cues, mood, interoceptive awareness, and consumption of food intake in healthy, naturally cycling women.

Apple Health Study

The Apple Health Study aims to build a diverse and inclusive group of participants to help researchers advance our understanding of how signals and information collected from apps and devices relate to health and may be used to predict, detect, monitor, and manage changes in health. To enroll, US residents who have an iPhone can download the Apple Research app from the App Store and go through the introduction and informed consent for the Apple Health Study. This study is fully remote, and all are invited to enroll if the eligibility criteria are met. Participants will be asked to complete tasks and surveys, using their iPhone and Apple Research app which include: * Selecting the types of data they would like to share with the study such as health and sensor data * Completing tasks and surveys including areas such as personal demographic information, personal medical history, family history, and social determinants of health

A Study of Abemaciclib (LY2835219) With Abiraterone in Men With Prostate Cancer That Has Spread to Other Parts of the Body and is Expected to Respond to Hormonal Treatment (Metastatic Hormone-Sensitive Prostate Cancer)

The purpose of this study is to learn whether adding abemaciclib to abiraterone plus prednisone prolongs the time before prostate cancer gets worse. Participation may last approximately 60 months.

Impact of Menstrual Cycle-Based Resistance Training on Neuromuscular Performance in Female Athletes

The goal of this clinical trial is to assess the impact of menstrual cycle-based resistance training on neuromuscular function in female athletes. The primary questions it aims to answer are : * Does varying resistance training intensity according to menstrual phases improve maximal knee extensor strength? * How do different training protocols affect voluntary activation, rate of force development, muscle stiffness, and vertical jump height? Researchers will compare natural menstrual cycle groups with an oral contraceptive control group to determine if menstrual phase-specific training influences neuromuscular adaptations. Participants will: * Undergo 2 weekly resistance training sessions over 13 weeks with intensity adjustments based on menstrual phase * Complete periodic neuromuscular assessments across three menstrual phases: early follicular, late follicular, and mid-luteal before and after resistance training intervention
