NCT07606885
This observational follow-up study extends a previously completed 15-day intensive longitudinal study (WeF) of the gut microbiome in healthy adults. The objective of WeF2 is to characterize the long-term stability and dynamics of the gut and oral microbiota in the same cohort across multiple timescales, and to determine whether the day-to-day variability patterns observed at baseline persist over months and years. Participants who completed the WeF baseline protocol will be invited to attend periodic follow-up visits for low-frequency biospecimen collection and to repeat the original 15-day high-frequency sampling protocol at planned intervals, beginning approximately six months after the WeF baseline and continuing at extended intervals thereafter. By combining sparse routine sampling with recurring high-density sampling windows, the study aims to distinguish the stable core microbiome from transient and seasonal fluctuations, to track gradual community shifts under free-living conditions, and to further explore relationships among microbiome dynamics, dietary intake, and host glycemic regulation over an extended observation period.

Limited ankle mobility can affect functional movement and balance, even in healthy individuals. Floss band application is a technique in which an elastic band is wrapped around a joint during active movement to potentially improve joint mobility and functional performance. Another approach combines floss band application with mobilization with movement (MWF), which integrates joint mobilization techniques during movement. This study examined the effects of floss band application on ankle range of motion (ROM), functional ROM, and static and dynamic balance in fifty healthy adults. Participants were randomly assigned to either a floss band group or a mobilization with movement floss band (MWF) group. Measurements were taken before and after the intervention.

The goal of this clinical trial is to validate if temporal interference brain stimulation (TIBS) is safe in healthy volunteers aged 20 to 65. The main questions it aims to answer are: * Is it safe to apply TIBS intervention to the left hippocampus in healthy participants? * Is it safe to apply TIBS intervention to the left insula in healthy participants? * Is it safe to apply TIBS intervention to the left anterior cingulate cortex in healthy participants? * Is it safe to apply TIBS intervention to the right inferior frontal cortex in healthy participants? Participants will: * Be Randomly allocated to either sham-first group or treat first-group, stratified by stimulated brain region, following a crossover-controlled experimental design * Complete baseline cognitive evaluations and mental status assessments, and undergo a baseline MRI scan on the same day * Receive stimulation for 5 consecutive days, followed by a 2-days washout period, then complete the remaining 5 days of stimulation. * Complete post-intervention cognitive evaluations and mental status assessments, and undergo a post-intervention MRI scan on the same day
NCT07245225
The goal of this study is to investigate the acute effects of drop-landing exercise on the bone metabolism biomarkers and extracellular vesicles in healthy young males, in order to gain a deeper understanding of the mechanotransduction mechanisms involved in bone metabolism. The main question aims to answer: • Does a single bout acute drop-landing exercise change serum sclerostin, other bone signaling markers, and circulating extracellular vesicles levels? Participants complete both the drop-landing and control trials in a randomized order, with a minimum washout period of one week between trials. During each trial, blood samples are collected at three time points: pre-, immediately post, and 1-hour post drop-landing/control exercise.

Sacroiliac joint (SIJ) dysfunction is a common cause of lumbopelvic instability, often linked to altered load transfer between the spine and lower limbs. Although various therapeutic interventions are used to restore joint alignment and improve neuromuscular control, the immediate effects of chiropractic manipulation on core stabilization in asymptomatic individuals remain unclear. This randomized controlled study aimed to examine the acute impact of bilateral sacroiliac joint high-velocity, low-amplitude (HVLA) manipulation on trunk stability in healthy adults. Sixty participants aged 18-40 years were randomly assigned to either a manipulation group or a control group. Core stabilization performance and postural control were evaluated using standardized tests including the Centaur Trunk Training (CTT) biofeedback system, plank, sit-ups endurance, and flexibility assessments. The findings demonstrated significant short-term improvements in trunk stability and flexibility following manipulation, suggesting that sacroiliac joint adjustments may positively influence neuromuscular activation and motor control in healthy individuals.

This study will determine the effect of dietary protein not absorbed in the small intestine on the bacteria in the large intestine and the metabolites those bacteria produce when they break down the protein. The three specific goals are: 1. Determine if increasing dietary protein increases the purine breakdown product, allantoin, as observed in our previous study. 2. Establish a model to examine the effect of dietary protein on the gut microbiota and metabolites. 3. Identify gut bacteria and metabolite changes that occur with increased consumption of animal (whey) or plant (pea) protein sources.
