Filter by:This study is conducted to evaluate the effectiveness of topical serum X containing arbutin and glutathione for skin brightening. The study duration is 12 weeks and the skin assessment will be carried out at baseline, week 4, 8 and week 12.The main questions this study aims to answer are: 1. The skin brightening effect of the product on facial skin. 2. To observe any adverse effect occurrence with the usage of the product.
The main purpose of this study in healthy participants is to find out whether the traditional ambulatory blood pressure monitor (ABPM) and newer wearable devices (EmbracePlus smartwatch device, Biobeat chest patch device, and Aktiia wrist device) will accurately pick up changes in blood pressure caused by 2 different medications (propranolol and pseudoephedrine). The study will last about 29 days excluding the screening period of 28 days.
Characterization of cortical activation patterns during movements in healthy adults may help our understanding of how the injured brain works. Upper limb motor tasks are commonly used to assess impaired motor function and to predict recovery in individuals with neurological disorders such as stroke. This study aimed to explore cortical activation patterns associated with movements of the hand and shoulder using functional near-infrared spectroscopy (fNIRS). The investigators hypothesized that the activation pattern observed with fNIRS would differ for shoulder and hand movements. More specifically, the investigators hypothesized that the cerebral activation during hand movements would mainly involve the contralateral hemisphere, particularly the lateral part of primary motor cortex; whereas activation during shoulder movements would be more medial and more extensive than that of the hand.
This study is conducted to evaluate the safety and effectiveness of facial cleanser X containing combination of olive oil, virgin coconut oil, butylene glycol and hyaluronic acid on skin hydration and skin elasticity. The study duration is 5 weeks and the skin assessment will be carried out at baseline, week 3 and week 5.The main questions this study aims to answer are: 1. The effect of product on skin hydration. 2. The effect of product on skin elasticity. 3. To observe any adverse effect occurrence with the usage of the product.
It is widely known that exercise creates structural and functional changes in the brain. Synaptic plasticity develops through exercise, thus improving brain functions. It is suggested that skeletal muscle contraction and peripheral signal molecules secreted from various tissues, especially skeletal muscle, contribute to exercise's effect on the brain's structure and function. These signals synthesized and released from skeletal muscle are called myokines. Brain-derived neurotrophic factor (BDNF) and Cathepsin B are two of these myokines, which have been reported to cross the blood-brain barrier following secretion in the periphery and affect the structure and functions of the brain. Transcranial magnetic stimulation (TMS) allows to evaluate the synaptic plasticity responses of the motor cortex to exercise, while cognitive function responses are evaluated via cognitive tests. Additionally, exercise type and intensity influence the responses of cortical excitability and cognitive function. This research proposal aims to investigate how acute high-intensity intermittent exercise (HIIT) changes primary motor cortex (M1) excitability, M1-related cognitive functions, and peripheral BDNF and Cathepsin B levels in healthy sedentary adults and to investigate the relationship between these neurophysiological parameters. All parameters will be measured before and after the acute exercise. M1 excitability will be evaluated through resting motor threshold, short interval intracortical inhibition, and input-output curve measurements. Cognitive functions will be evaluated through mental rotation and working memory tasks, and peripheral signal responses will be measured by serum levels of BDNF and Cathepsin B. Our hypotheses are: 1) Acute HIIT will increase peripheral BDNF and CTSB level, cortical excitability, and M1-specific cognitive function performance. 2) M1 excitability, cognitive function performance, and peripheral BDNF and CTSB increase will be related following exercise. Our findings will have the potential to be a guide for the integration of exercise into daily life and will provide cortical and peripheral data on the neurophysiological basis of the relationship between exercise and cognition.
Randomized study to determine whether the vaginally isolated strains of Lactobacillus gasseri and/or Lactobacillus crispatus can colonize the vagina when taken orally for 18 days. Secondary outcomes comprise evaluation of safety, tolerability, impact on vaginal microbiota and vaginal pH
The goal of this clinical trial is to learn about the effects of phase-targeted auditory stimulation in depressed patients and healthy controls. The main questions it aims to answer are: - Is auditory down-phase stimulation efficient in improving depression symptoms as compared to sham stimulation? - Can mood and other outcomes be prospectively estimated by multi-parametric passive data? Participants will perform auditory stimulation using a wearable device at home and provide data on their phone usage and activity. Researchers will compare depressed patients and healthy participants to see if auditory down-phase stimulation effects them differently.
The purpose of this study is to evaluate the SpO2 accuracy and performance of the Norbert Device during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-oximetry for SpO2 validation.
The purpose of this clinical trial is to learn about the safety of the study medicine (ponsegromab) and how it undergoes change and elimination in healthy Chinese adults. This study is seeking male and female Chinese participants who are very healthy as confirmed after some medical tests. All participants in this study will receive Ponsegromab only once: - for half of the participants, ponsegromab will be given as a shot in the front of the thigh, abdomen, or outer area of the upper arm at the study clinic. - for another half of the participants, ponsegromab will be given as four shots in the front of the thigh, abdomen, or outer area of the upper arm at the study clinic. We will measure the amount of the study medicine in the blood of the participants after giving the shots. Later we will examine experiences of people receiving the study medicine. This will help us understand how the medicine is changed and eliminated from your body and to decide if the study medicine is safe. Participants will take part in this study for 22 weeks. During this time, they will stay at the study clinic for the first 8 days and will visit the study clinic about 8 times.
