Research Into the Safety of a New Agent (VT-5006) in People With and Without Parkinson's Disease

This is a first-in-human (FIH) study of orally administered VT-5006 (also known as AX-5006) in healthy adult volunteers (HVs) and adult participants with Parkinson's disease (PD). The goal of this clinical trial is to learn if VT-5006 is safe and tolerable in healthy volunteers and in participants with PD. It has three Parts (A, B, and C). Part A: Healthy volunteers aged 18-54 will attend a screening visit, take a single dose of VT-5006 or matching placebo after an overnight fast, stay in the clinic for three nights, and complete a follow-up visit. One group of participants in Part A will be asked to return to the clinic after approximately two weeks, take a single dose of VT-5006 or matching placebo after consuming a high-fat meal and stay in the clinic for another three nights. Part B: Healthy volunteers aged 18-54 will attend a screening visit, take one dose of VT-5006 or matching placebo each day for seven days after fasting overnight, stay in the clinic for 10 nights, and complete a follow up visit. Part C: Participants with PD aged 40-80 will attend a screening visit, take one dose of VT-5006 (high dose), VT-5006 (low dose), or matching placebo each day for 28 days, complete two overnight stays in the clinic, attend three clinic visits, one phone call and a follow up visit.

Effects of a Sleep Education Program on the Health Status of Healthcare Workers Working 12-hour Alternating Day-night Shifts

In a context of seeking a better balance between personal and professional life and labor shortages, the use of 12-hour alternating day-night shifts has become more common in work organizations, particularly in healthcare facilities. This work pattern combines exposure to alternating day and night shifts with long working hours, raising questions about its effects on health, particularly sleep quality and cardiovascular risk. Staff working alternating day/night or night shifts are at risk of cardiovascular disease, particularly in connection with sleep deprivation and the adoption of individual behaviors that increase the risk (smoking, poor diet, alcohol consumption, smoking and low physical activity). However sleep education is not integrated in a personalized way into the prevention advice provided by occupational health services. Therefore, this study aims to investigate the effects of a 6-month sleep education program conducted by occupational health nursing staff, on the sleep duration of healthcare workers newly exposed to alternating 12-hour day and night shifts.

Phase I Study of HXN6005 in Adult Healthy Participants

The goal of this clinical trial is to evaluate the safety, tolerability, pharmacokinetic characteristics and pharmacodynamics of HXN6005 in Healthy Participants. Researchers will compare HXN6005 to a placebo (a look-alike substance that contains no drug). Participants will take a single dose of HXN6005 or placebo on Day 1, and visit the clinic for followup and tests per the protocol scheme.

Signature Development and Validation Protocol for an Epigenetic Assay in Diagnosing Breast Cancer

The purpose of this research study is to test a new process for diagnosing breast cancer by examining changes to your DNA that can be detected from a blood test. The information we learn by doing this study could potentially help people in the future. Participants in this study will have blood samples collected, have their medical records reviewed by study personnel and fill out questionnaires at different time points during the study. Blood sample collection will occur during normal routine clinic visits. Participation in this study will last approximately 5 years.

Examining the Effects of Reformer Pilates Exercises on Physical Fitness and Cognitive Functions in Healthy Individuals

Pilates is an exercise method that aims to increase body awareness and improve physical fitness through controlled movements based on mind-body integration. Reformer Pilates strengthens the mind-body connection while increasing core muscle activation through equipment-assisted exercises. It is known that regular exercise has positive effects on cognitive functions through its neuroprotective and neuroplastic effects. However, the effects of Reformer Pilates on these functions have been studied in only a limited number of studies, particularly in healthy middle-aged individuals. The aim of this project proposal is to investigate the effectiveness of Reformer Pilates exercises on physical fitness and cognitive functions in healthy individuals. In this study, the effects of reformer Pilates on physical fitness and cognitive functions will be examined in healthy individuals aged 18-50. The intervention group will perform reformer Pilates twice a week for 8 weeks, while the control group will not participate in any physical activity. Body mass index, waist-to-height ratio, waist-to-hip ratio, cognitive reserve, cognitive functions, reaction time, physical fitness, grip strength, and general health status will be assessed at baseline and after 8 weeks. Cognitive functions will be assessed using the cognitive reserve index, and cognitive functions will be assessed using the Stroop test-anchor form and the tracking test. Stroop test-anchor form and tracking test; reaction time will be measured using a wireless system consisting of a laser LED light emitter and a central hand control unit; physical fitness will be assessed using The Senior Fitness Test; grip strength will be measured using a hand dynamometer; and general health status will be assessed using the General Health Questionnaire-12. Data analysis will be performed using SPSS version 25.0. For comparing pre- and post-treatment outcome measures within the group, analysis will be conducted using the t-test for dependent samples (if normally distributed) or the Wilcoxon signed-rank test (if not normally distributed). Effect size will be calculated to determine the impact of the exercise program. P\<0.05 will be considered statistically significant.

Effects of Integrative Neuromuscular Traning on Physical Fitness and Dribbling Performance Among High School Male Football Players in Shandong, China

This study investigates the effects of a 12-week Integrative Neuromuscular Training (INT) program on physical fitness, balance, and dribbling skills in male high school soccer players in Shandong, China. INT, which combines strength, agility, balance, core stability, and proprioception, has been shown internationally to enhance athletic performance and prevent injuries among youth athletes. While widely applied in sports like basketball, volleyball, and swimming abroad, research on INT in Chinese male soccer players remains limited. A total of 60 male soccer players (aged 16-18) with at least two years of training experience will be recruited from two high schools in Jinan and divided equally into experimental and control groups. The experimental group will undergo INT three times per week for 12 weeks, while the control group will continue regular soccer training. The study will measure changes in strength, speed, endurance, flexibility, static and dynamic balance, and dribbling performance. Data collection spans 16 weeks, including pre-tests, intervention, and post-tests. Statistical analysis will be conducted using SPSS 26.0, employing descriptive statistics, GEE models, and repeated measures ANOVA. This research aims to provide scientific evidence for the use of INT in youth soccer training in China.
