NCT07227259
The main goal of this clinical study is to see if consuming pecan nuts will result in improvements in overall body metabolism such as in blood lipids, markers of inflammation, blood pressure, cognitive performance and changes in bacteria living in the gut in adults 45 to 75 years of age. Participants will take part in two 3-month intervention periods, separated by 4-6 weeks, in random order ( a total of approximately 7 months). During one intervention period, they will include pecan nuts in their diet each day, while during the other intervention period they will avoid pecans in their diet. There will be an initial screening visit to evaluate eligibility and four study visits to the clinic. Participants will be asked to complete some questionnaires about their diet, physical and cognitive health, and provide blood and stool samples, and have their blood pressure measured.

This is a single center, open label (i.e. participants and study staff will not be masked to the intervention) single ascending dose study to evaluate the safety, tolerability, pharmaokinetics and pharmacodynamics of MIB-725 in community dwelling, healthy adults. Up to 4 successive groups (cohorts) of 8 subjects each will be enrolled in this trial. This study will determine the safety and tolerability of orally administered single ascending (increasing) doses (100, 200, 400, and 800 mg) of MIB-725 in healthy adults. The safety will be assessed by evaluating physical examination that includes an external eye examination, vital signs, adverse events, and changes in blood counts, EKG, urinalysis, coagulation measures, and blood chemistries, including but not limited to blood glucose, electrolytes, creatinine, liver function tests, uric acid, and creatine kinase.
NCT04933656
In this research study, the investigators will use a novel approach to measure what people eat. The goal is to find out whether stable isotopes that can be measured in blood, hair, and fingernails are better at measuring what people eat than the surveys that are currently used. To meet the goal, the investigators will do three things. First, the investigators will feed study participants known amounts of foods and nutrients. Second, after study participants have eaten the food, the investigators will measure stable isotopes in samples of study participants' blood, hair, and fingernails. Third, the investigators will determine how well these samples reflect what was eaten. The investigators will also give surveys to study participants to determine how well the surveys reflect what was eaten. This will allow the investigators to do a relative comparison of the measurements from isotopes and surveys.
NCT07305753
The aim of this study is to develop a dataset with reference body composition measurements using criterion methods. This dataset will be used to develop new protocols to study patients with cancer. Obtaining measurements of sodium bromide (NaBr), deuterium dilution (D2O), and D3-Creatine in a stratified sample of adults will determine the accuracy (and precision) of the available devices for ECW, TBW, and skeletal muscle mass measurements.
NCT07301112
With the third wave of the Transitions and Old Age Potential (TOP) study, the longitudinal study of initially 5,002 individuals was completed in 2019. Initial findings were published in 2020 through a brochure, policy brief, and methodological report, and presented publicly. The third wave produced two datasets: a panel of 1,561 individuals surveyed across all three waves (2013, 2015/16, 2019) and a couple datasets with 576 complete interviews. Additional data sources such as DEAS, FWS, and SHARE complement the analyses. In 2021, efforts centered on preparing scientific articles for peer-reviewed journals and archiving the third wave at GESIS Leibniz Institute for the Social Sciences, concluding the study that ran from 2011 to 2021.

NCT07275619
Cardiorespiratory fitness (CRF) is a physical attribute which represents how effectively various bodily systems work together to transport and utilize oxygen to support muscular activity during prolonged, rhythmic, large-muscle, whole-body exercise. A key element associated with physical fitness is VO2max, which is referred to as cardiorespiratory fitness. Queen's college step test will be used to estimate the VO2max. This study will be cross sectional, normative study. Healthy adults aged 18-65 years from community setting will be recruited through non probability convenient sampling technique to collect data as per inclusion criteria. Sample size will be approximately 800, consist of equal ratio of males and females. Heart Rate, Recovery Heart Rate, VO2 max and METS will be calculated of each subject. Following equation is used to calculate VO2max, for females: VO2max = 65.81- \[0.1847× HR\] for males: VO2max = 111.33- \[0.42× HR\]. Data analysis will be conducted by using SPSS (Statistical Package for the Social Sciences) version 28.

This is a phase 1, open-label, non-randomized, parallel-group, single-dose study to assess the effect of hepatic impairment (assessed by the criteria of the Child-Pugh scale) on the pharmacokinetics (PK) and safety of KP-001 in adult male and non-childbearing potential female participants aged ≥20 years old. The purpose of this study is to evaluate the effect of hepatic impairment on the PK and safety of KP-001. The study will also assess the effect of hepatic impairment on other PK parameters after single dose administration of KP-001. The study will comprise 3 parts, and the study period for each part will consist of the following: * Screening period: Up to 28 days before the administration of study intervention * Treatment Period: Participants will be residential at the Clinical Unit from the day before the administration of the single dose of KP-001 (Day -1) until Day 3 (Discharge) * Follow-up Visit: 7 days after discharge from the Clinical Unit (ie, Day 10) Participants will be enrolled into 4 cohorts according to the hepatic function status as summarized below. The study includes a control group of healthy participants with normal hepatic function.
NCT06811545
The goal of this study is to see if gentle electrical stimulation can help children with cerebral palsy (CP) walk more easily. This stimulation, called neuromuscular electrical stimulation (NMES), sends small pulses to muscles to help them activate. Researchers will test different ways of using NMES to find out which method works best. Participants will walk on a treadmill at a comfortable speed while NMES is applied to leg muscles. The study will compare different stimulation settings to see which one helps the most.

NCT07027982
This study will evaluate the pharmacokinetics and safety of Diluted and Undiluted Intravenous DA-5217 in healthy adult subjects.
NCT07117292
This study aims to evaluate how accurate and reliable two wearable sensor systems (inertial measurement units or IMUs) and a goniometer are in measuring cervical spine (neck) motion. Healthy adult volunteers will be asked to perform simple head movements in different directions while being assessed using the devices. The goal is to compare how closely these tools agree with each other and how consistently they record motion across repeated tests. This information will help determine whether the sensors are suitable for use in clinical settings to assess neck movement in future patient populations.

Respiratory muscle training (RMT) strengthens breathing muscles and may improve exercise performance and reduce breathlessness. However, different training methods and devices create controversy in the field. Two main types of RMT exist: inspiratory muscle training (IMT) and respiratory endurance training, like voluntary isocapnic hyperpnea (VIH). While IMT is well-studied, the impact of VIH on breathlessness remains unclear. This study will use the Canadian-developed BreathWayBetter device to examine how 5 weeks of VIH affects breathing discomfort and muscle function. Findings may help personalize RMT for athletes and clinical patients, improving respiratory care and exercise tolerance.
NCT07033793
Student musicians are particularly vulnerable to both physical and psychological health issues, with studies showing that 38% report pain from musical practice and over 50% experience high stress. Despite these risks, health resources tailored specifically to student musicians remain limited. This study aims to address this gap by testing a preventive, digital intervention to improve the well-being of this population. The intervention, delivered via a smartphone or tablet app, is designed to accommodate the unique demands of student musicians, such as frequent travel and time constraints. It includes health education, self-assessment tools, preventive health behavior advice, and interactive games designed to promote healthier work habits, daily routines, and overall health knowledge.
NCT06312930
Transcranial pulse stimulation (TPS) is a newly developed non-invasive brain stimulation (NIBS) technique from Austria \& Germany with highly promising applicability in neuropsychiatric disorders. Clinical trials have shown a beneficial effect of TPS in patients with Alzheimer\'s disease and depression. However, the mechanism of action of TPS treatment is unknown. There is a lack of controlled studies with sufficient sample size to draw reliable conclusions on the modulatory effect of TPS. The primary motor cortex is a common target when investigating the neuromodulation effect of NIBS techniques. Here, a randomized, cross-over, single-blind, sham-controlled clinical trial is proposed to probe the effects of TPS over the primary motor cortex on modulating motor response and motor behavior.
NCT06116838
The goal of this study is to understand how transcutaneous spinal cord stimulation (tSCS) waveform, modulation frequency, and stimulation location impact lower extremity muscle activation and participant comfort in adults without neurologic conditions.

Dietary intake of galacto-oligosaccharides (GOS) may have beneficial effects on host health by affecting the microbiota composition and -activity. So far studies focused on analyses in fecal samples, while the primary site of carbohydrate fermentation is the proximal colon. To date, no studies have been performed in humans on the more proximal microbiota and the impact of fermentable carbohydrates. Further insights on the more proximal colonic microbiota would aid to targeted approaches to improve intestinal health. Therefore, we aim to study the effect of GOS on the intestinal microbiota composition and -activity in healthy adults, by sampling the more proximal human colon in a physiological condition. The primary objective of this study is to investigate the impact of four weeks GOS supplementation on intestinal microbiota composition and -activity, by sampling the proximal part of the human colon in a physiological condition. Furthermore, this study has four secondary objectives: First, to compare the intestinal microbiota composition and -activity of the proximal colon vs. distal colon at baseline and after four weeks GOS supplementation. Second, compare the luminal microbiota composition vs. mucosa adherent microbiota composition of the proximal vs. distal colon at baseline and after four weeks GOS supplementation. Third, monitor the effects of four weeks GOS supplementation on gastrointestinal symptoms. The study conforms to a randomized, double-blind, placebo-controlled, parallel design. Study population includes healthy human volunteers (male and female), 18-50 years of age. One intervention arm will include 7.2 grams of Vivinal® GOS Powder three times daily for four weeks. The other intervention arm subjects will receive placebo product (7.2 grams maltodextrin) three times daily for four weeks. At the start and end of the intervention period, several measurements will take place. The main study parameter is the change in microbial composition and -activity induced by GOS intervention.

Since the 19th century, perception has been regarded as an inferential process in which sensory input is compared with prior knowledge, namely the internalised representation of the visual environment. This notion is central to the understanding of everyday perception and cognition in general, and is attracting much attention in various areas of psychology and cognitive neuroscience. However, it is unclear whether and how the primary visual refinement that is thought to underlie the convergence of bottom-up inputs with top-down prior knowledge applies to the processing of meaningful stimuli in our everyday lives. The investigators have shown that human face processing mechanisms are shaped by prior knowledge that the horizontal range of face information conveys the richest and most reliable cues. Furthermore, investigators' previous data suggest that the primary visual cortex is recruited during the progressive refinement of face representation. Using very high field neuroimaging, the present project proposes to follow the neural mechanisms underlying the cortical refinement of horizontal information in human face processing, and to study their contribution to behaviour.
NCT06411782
The aim of this study is to examine the acute effect of the foam roller (FR) method applied to the sternocleidomastoid (SCM) muscle after respiratory muscle fatigue on joint range of motion (ROM), accessory respiratory muscle activity and muscle strength. The aim of this study is to examine the changes in fatigue and pain symptoms by applying relaxation on the tense fascia and shortened muscle as a result of resistance training, and the effect of these changes in the sternocleidomastoid (SCM) muscle on joint range of motion (ROM) and muscle strength in healthy male or female participants aged 18-30. In line with the investigators' results, it may be recommended to add foam roller (FR) to the accessory respiratory muscles in the pulmonary rehabilitation program in patients with chronic lung diseases. For this reason, the investigators think that it will provide clinical and scientific benefits. The investigators believe that it will lead studies to add foam roller (FR) to the pulmonary rehabilitation program in patients with chronic lung diseases. Participants will be informed about the risks and benefits of participating in the study and a voluntary consent form will be signed. Participants will be given a demographic data form before starting the study and will be asked to fill it out. The hypermobility value will be measured according to the Beighton score before the participants start the tests. After the inspiratory muscle training (IMT) study, foam roller (FR) will be applied to the right sternocleidomastoid (SCM) muscle. A one week washout period will be given. Afterwards, the cases will be applied foam roller (FR) to the left sternocleidomastoid (SCM) muscle after the inspiratory muscle training (IMT) study. All evaluation parameters will be repeated before and after the applications. Maximum inspiratory pressure measurement, range of motion (ROM) measurements, muscle strength tests, flexibility with a myotony measuring device, electromyography (EMG) measurements will be made before the study one by one.
