NCT07577622
Strength exercise is an active and dynamic activity that involves applying force against a resistance. This produces fatigue, seen as a reduced ability to apply force during and after the exercise, and perceived effort, which is a person's subjective feeling of how hard they are working. Strength exercise can also be used for therapy, as it has many benefits for different parts of the body. One of these is changing how the individual feels pain. It has been shown that doing strength exercises can reduce pain perception, a phenomenon called exercise-induced hypoalgesia (EIH), although the exact physical reasons and the amount of exercise needed to cause this effect are not yet known. One of the most studied exercises in this area is the leg extension machine. This is a specific exercise where the legs move freely (open kinetic chain) and the machine guides the movement, which helps keep things stable and limits the effect of other factors. It is usually used to strengthen and grow the muscles in the front of the thigh, especially the quadriceps, but it can also be used to study the effects on EIH. The main goal of this study is to see if fatigue and perceived effort during strength exercise are important for EIH to happen in healthy people. Participants will complete 3 sessions, at least 7 days apart. These will include a control session and 2 sessions designed to show different levels of fatigue. Before, during, and after the sessions, the investigators will measure pain sensitivity, isometric strength, and perceived effort. Also, there will be a test to find the maximum weight for 10 repetitions and several questionnaires to collect basic info (sex, age, height...), weekly physical activity, experience with strength training, and other factors like sleep quality, stress, and mood. All this information will be completely anonymous when the study results are shared.

NCT05966532
This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 120 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 120 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.
NCT07300202
This Phase I clinical study is designed to evaluate the safety and determine the maximum tolerated dose (MTD) of Orialpha (BD-C) in healthy adult volunteers.
NCT07182500
Journeying along the historic Silk Road exposes travelers to dramatic dietary shifts, unfamiliar microbial environments, and the physical stresses of long-distance travel-all known to disrupt gut health and cause gastrointestinal complaints, including traveler's diarrhea and sleep disturbances. Such disruptions may also elevate the risk of acquiring antibiotic-resistant organisms. This randomized, double-blind, placebo-controlled trial evaluated whether probiotic supplementation can help maintain gut microbial balance and support traveler well-being during trips to Silk Road regions. In addition to monitoring changes in gut microbiota composition, the study assessed gastrointestinal symptoms, sleep quality, anxiety levels, overall well-being, gut immune markers, functional profiles of the microbiome, and the presence of antibiotic resistance genes.
NCT06681389
This Phase 1b/2a clinical development plan is focused on the use of NP-201 acetate injection to investigate the pharmacokinetics (PK), safety, efficacy, PD (pharmacodynamic) markers (Phase 1b) and tolerability of NP-201 acetate injection after subcutaneous (SC) injection of multiple doses in healthy adults and in the ulcerative colitis (UC) patient population.
NCT05162274
This Clinical Trial is an open, randomized, fasted, single-dose, oral administration 2-sequence, 2-period crossover study to assess bioequivalence of lazertinib between two formulations in healthy adult volunteers. The subjects administer 240mg of lazertinib of different formulations on the fasted status on each period and have a wash-out period for 14-21 days between the first and second period.
NCT05017987
To compare and evaluate safety and pharmacokinetic Characteristics after administration of ATB-101 or co-administration of ATB-1011 and ATB-1012 in fasted Healthy Adult Volunteers
NCT04204772
This is a pilot study designed to test feasibility, tolerability, and safety of medical grade oral Activated Charcoal (AC) in 12 healthy volunteers. To determine the two most palatable and tolerable AC combinations. There will be a total of 4 combinations (2 AC doses and 2 solutions) in stage 1. Each participant will drink an assigned combination every day for 3 consecutive days (Monday, Tuesday, Wednesday, "M/T/W") and switch to a different assigned combination M/T/W the following week. AC solution assignments will be defined before the study using a balanced incomplete block design. Each subject will rate their experience using a 5-point scale every day for the 12 days they are on study.
NCT05074368
The investigators conduct a prospective analysis to compare homologous and heterologous adenovirus vector ChAdOx1-nCov-19 (Astra-Zeneca) or SARS-CoV-2 messenger RNA-1273 (Moderna) vaccine inoculation. Healthy volunteers will be enrolled and divided into five groups. The first group is the subjects who received ChAdOx1- nCov-19 vaccine with 8 weeks apart; the second group is the SARS-CoV-2 messenger RNA-1273 vaccine after the first dose of ChAdOx1-nCov-19 vaccination with 8 weeks apart; the third group is the first dose of ChAdOx1-nCov-19 vaccine and the SARS-CoV-2 messenger RNA-1273 vaccine with 4 weeks apart; the fourth group is the SARS-CoV-2 messenger RNA-1273 vaccination with 4 weeks apart; the fifth group is the first dose of ChAdOx1-nCov-19 vaccine and the SARS-CoV-2 messenger RNA-1273 vaccine with 12 weeks apart. There will be 100 volunteers in each group. Antibody test on the day before and the 14th, 28th day and 12th week after the second dose of vaccination, including 100 subjects in each group for SARS-CoV-2 ELISA antibody titer and 50 people in each group for SARS-CoV-2 neutralizing antibody titer. Adverse reactions at the first day, the 14th day, the 28th day, and the 12th week. The research team follow up each volunteer at the 6th month.
NCT01672242
Respiratory distress is a common problem in an intensive care unit. There are multiple mechanisms that are used to help patients who are in respiratory distress including mechanical ventilation, continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), high flow oxygen, and oxygen supplementation through nasal cannula or a facemask. The purpose of this study is to evaluate the mechanism by which Vapotherm, a high flow oxygen system, provides breathing support. Vapotherm provides high flow oxygen at different flow rates, meaning one can increase the amount of oxygen flow to help with breathing support. The investigators believe that this high flow oxygen system may provide similar breathing support that a continuous positive airway pressure machine (CPAP) machine does.
NCT02942771
The purpose of this Study is to find out whether an investigational drug is safe and well tolerated. MW189 is being studied as a possible short-term treatment for people with different types of brain injury. MW189 has previously been given to healthy human volunteers as a single dose, and there were no significant problems or bad effects in people who received the Study drug. However, before it can be tested in people with brain injury, it is important to test MW189 in healthy volunteers when given multiple doses.
NCT03748758
The purpose of this study is to evaluate the safety and tolerability of two dose levels of OP0201 and placebo, when administered intranasally in healthy adults subjects.
NCT01354379
The purpose of this study is to test the safety and immune response of a new intranasal vaccine against influenza, called NB-1008. The vaccine is composed of a licensed vaccine that is normally given as an injection, called Fluzone, and an adjuvant (additive that helps a vaccine work better), called W805EC. In a prior clinical study this vaccine showed promising results in terms of being well tolerated and eliciting mucosal and systemic immune responses after administration by a dropper. In this study NB-1008 is being administered by dropper as well as a nasal sprayer to determine if the sprayer further enhances the immune response.
