Filter by:The aim of this randomized cross-over study is to collect information for the design of a precision exercise therapy cohort that will predict what modality of physical activity a physically inactive individual with overweight should perform to increase insulin sensitivity given their unique biology, environment, and context.
This study is a single-center, randomized, double-blind, placebo-controlled, dose-increasing phase I clinical study.
This study is conducted to investigate the safety and efficacy of the formulation containing stem cell secretome and licorice root extract in improving vagina laxity (VL) condition of women in Malaysia. This formulation may stimulate cell rejuvenation and trigger cell renewal efficiently as they contained rich mixture of natural, bioavailable polypeptides and plant extracts and these might help improving the VL condition in women. The study duration is 5 weeks and vagina assessment will be carried out at baseline, week 2 and week 5.The main objectives of this study are: 1. To assess the vagina laxity of women in Malaysia after using the formulation. 2. To observe any adverse effect occurrence with the use of the formulation.
The aim of the study is to evaluate autonomic function and cerebrovascular control in 30 healthy subjects by means of noninvasive analysis of time series variability. To this extent, heart period, systolic and mean arterial blood pressure, cerebral blood velocity, peripheral resistances, respiration will be recorded from subjects during an orthostatic challenge. The interactions between autonomic cardiovascular function, cerebrovascular and peripheral control will be evaluated exploiting the most advanced signal processing techniques.
This is a single-center, randomized, open study to evaluate the pharmacokinetics, safety and immunogenicity CM310 in healthy subjects.
The goal of this clinical trial is to give an answer to the question of whether an automated calculation of voided volumes would produce a more accurate set of bladder diary data when compared to the traditional ''eye-balling'' method of estimated voided volumes of paper bladder diaries, in female adult patients with lower urinary tract symptoms (LUTS). The main question[s] it aims to answer are: - Does an automated measurement of voided volumes improve the accuracy of bladder diary data? - Does an automated measurement of voided volumes improve the utility of bladder diaries? Participants will be asked to: - void in the disposable measuring jug and record their estimated voided volume for a total of three consecutive days in a paper diary (as per usual care). - transfer their voided volume from the disposable jug to the automated vessel (diary pod) after each void for the same three consecutive days. The reports generated from the paper diaries (estimated volumes) will be compared to the reports generated from the electronic automated measurement of voided volumes to understand whether there is a clinically significant difference between the two. The investigators aim to recruit healthy female adult volunteers with no lower urinary tract symptoms to understand the normal voiding patterns and volumes of adult females using the diary pod. The investigators will also recruit adult females with lower urinary tract symptoms and compare the two methods of capturing the voided volume
The purpose of this research is to compare sympathetic function (flight or fight system) and arterial health including structure and mechanics of participants with history of spontaneous coronary artery dissection (SCAD) to age and sex matched control participants.
Gut microbiota produce different metabolites within the human body, which include neurotransmitters. Animal studies have demonstrated a critical role for the gut microbiota in various aspects of brain and behavioural function, and a smaller number of studies in humans have shown differences of gut microbiota composition in psychiatric conditions. However, almost nothing is known about the impact of neurotransmitters produced by the gut microbiota on human brain and behaviour. The way in which differences in brain, behaviour and personality traits are associated with the gut microbiota, and how they are influenced by a probiotic will be explored, with a special focus on GABA (Gamma Amino Butyric Acid). Abnormalities of microbiota composition have been identified in metabolic disorders, such as inflammatory bowel disease and obesity, and psychiatric conditions, such as depression and anxiety. The aim of this intervention trial will be to answer the following fundamental questions: 1. Does the population of gut bacteria capable of producing GABA modulate brain-based measures of GABA? 2. Does the population of gut bacteria capable of producing GABA influence performance in behavioural tasks known to depend on GABA-ergic function? The impact of a GABA producing probiotic on the measures of GABA in the brain and serum, relevant metabolites in blood, faecal and urine samples and performance in GABA dependent behavioural tasks will be investigated in this trial.
The objective of the NAD-brain study is to determine the blood and brain pharmacokinetics of NAD replenishment therapy (NRT) using Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN).
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.
