MATERIAL AND METHOD: 46 healthy young individuals aged 19.2(±1.5) years participated in the study. The participants were randomly divided into 3 groups as Above Threshold Group (n:15; 10 females, 5 males), Under Threshold Group (n:15; 10 females, 5 males) and Control Group (no stimulation) (n:16; 11 females, 5 males) according to the sensation of electrical current on ears. The participants were evaluated 3 times; before the application, after the first and second bicycle exercises. Numerical pain scale (NPS), pulse rate, blood pressure, respiratory rate, and distance travelled during exercise for sportive performance were recorded in kilometers as the evaluation method. The stimulation was done during the first bicycle exercise with 5 minutes of duration. The Kruskal-wallis, mann-whitney u test were used for the quantitative independent data obtained. In the analysis of qualitative independent data, chi-squared test was used.
Rivaroxaban is a direct oral anticoagulant that target specifically activated factor X. Bleeding events related to rivaroxaban are the consequence of physiopathologic, pharmacokinetic issues or poisoning. A recent study, in healthy subjects, shows that activated charcoal can reduce significantly exposition to rivaroxaban. However, no results are available on the minimal dose of activated charcoal necessary in rivaroxaban poisoning. The objective of this study is to evaluate the effect of 4 dosing regimen activated charcoal on rivaroxaban pharmacokinetics. It corresponds to a randomised open trial with an incomplete cross over design (3 occasions). It will enrol 12 healthy subjects. Four treatments modalities will be studied: rivaroxaban with 50g, 24g, 12g and 6g of activated charcoal administrated 3 hours after rivaroxaban intake.
A single centre, placebo controlled, blinded (participant, investigator, outcome assessor) trial to evaluate the effects of COX-2 inhibition with celecoxib on endothelial function in healthy male volunteers.
Control of the dynamic functional leg alignment (dFLA) and biomechanical load are important joint related aspects regarding the development of osteoarthritis (OA). Research on level walking with feedback on load related parameters provided innovative treatment possibilities. Concerning walking on sloped surfaces, fundamental biomechanical knowledge exists. However, deeper insights into the control of the dFLA during decline walking, and the usefulness of real-time feedback are missing. This study is set up as cross-sectional observation of gait under four conditions, which follows a randomized sequence in order to avoid carry over effects. Thirty (30) participants aged between 18 and 35 years will be included. They will complete a three-dimensional gait analysis on a 5-m ramp with 10° inclination. Afterwards they will be observed under four different conditions a) self-paced walking b) self-paced walking with internal focus of attention, c) self-paced walking with real-time feedback, and d) condition c speed-matched walking, on a 10° declined split belt treadmill. The primary outcome parameter will be the frontal knee range of motion (fKROM). Secondary outcomes include the ground reaction force loading rate, spatial-temporal parameters, sagittal frontal and transversal kinematics, and kinetics for the lower extremities. The findings should improve the understanding of effects of real-time feedback on the control of the dFLA and lower limb loading. Results will be published in a peer-review journal.
An open-label, randomized, single-dose crossover study to evaluate the pharmacokinetics, safety and tolerability of HCP1903 in healthy subjects.
The purpose of the study is to assess the effect of dietary intervention that includes the daily consumption of a novel biscuit (enriched with the selected mushrooms rich in β-glucans) on gut health related parameters of healthy subjects over 60 years old.
This is a Phase 1, open-label, non-comparative study in healthy subjects performed in the US. It is designed to assess systemic exposure to articaine and its metabolite articainic acid after dosing a single topical ocular administration of AG-920 in the randomized study eye.
The main purpose of this study is to evaluate the safety and tolerability of LY3549492 in healthy participants. The blood tests will be performed to check how much LY3549492 gets into the bloodstream and how the body handles LY3549492. This study includes two parts and will last up to approximately 76 days for each participant, including screening.
Attention may influence the motor performance and frontal activity. This study will examine the effect of different attentional focus : internal, external and divided attention (dual task) on prefrontal cortical activation (fNIRS) and on gait performance. Thirty young healthy voluntary adults will participate in this study.
The 3Sm challenge study is a small clinical study in eight healthy volunteers who will be injected with a protein which includes a short portion ('3Sm peptide') which is derived from a part (the '3S region') of the coat protein of HIV. The researchers believe that the 3Sm peptide might trigger an immune response which includes rare antibodies able to neutralise a wide range of different strains of HIV. The results will be useful in guiding the development of future vaccines against HIV, and other diseases.
