Filter by:This study aims to evaluate the efficacy of fecal microbiota transplantation on the gastrointestinal symptoms, autistic symptoms and emotional behavior symptoms of patients with autism spectrum disorder, and investigate the relations between the brain-gut axis, cytokines and autism spectrum disorder. Fecal microbiota transplantation have the potentials to improve intestinal microbiota composition, regulate immunity, and then improve gastrointestinal symptoms, autistic symptoms, emotional behavior symptoms and sleep of children with autism spectrum disorder. Early intervention at school-age may even benefit development, improve cognition and prognosis.
Multiple studies have highlighted music's ability to evoke diverse emotional states. Past research reveals that factors like musical elements, and the environment impact how people respond emotionally to music. For instance, faster tempos tend to heighten arousal, while minor key compositions evoke more arousal compared to major key compositions. In efforts to induce specific emotions post-stress, the research found that both pleasant and sad music aided stress recovery. Similarly, other researchers noted that positively rated music was more effective in reducing stress than negatively rated music, especially low arousal compositions over high arousal ones. Several studies focused on applying music to reduce stress and anxiety. In addition to man-made musical tones, the positive impact of natural surroundings on emotional state has been widely explored. A psycho-evolutionary viewpoint was offered, suggesting that humans have evolved in natural settings, making us inherently attuned to them physically and psychologically. A non-threatening natural environment, rich in aesthetically pleasing elements like visible escape routes, greenery, and water, tends to reduce stress and generate interest. In this study, the researchers are exploring how different sounds-man-made instrumental music versus natural sounds-affect stress, anxiety, and mood among the students of Medgar Evers College. Using an experimental approach, the researchers will assess pretest stress levels (via the perceived stress scale (PSS), anxiety (generalized anxiety disorder (GAD-7), and mood (four-dimensional mood scale (4DMS) among a sample of students. After randomly dividing them into two groups, each group will listen to one of the designated sounds (man-made music or nature sounds) for 30 minutes daily over 15 days. The researchers will then have them retake the stress, anxiety, and mood scales for post-test comparison. Statistical analysis (mixed ANOVA) will help to compare scores within and between groups. Ultimately, this study aims to determine the influence of tonal input on stress and anxiety levels among students, crucial given the significant stress they often experience.
This study is a single center, randomized, open/double-blind, placebo-controlled, single dose, dose escalation Phase I clinical study aimed at evaluating the safety, tolerability, pharmacokinetics, pharmacokinetic characteristics, and immunogenicity of CM313 administered subcutaneously or intravenously at different doses in healthy male subjects.
Respiratory muscle training represents an effective method increasingly utilized in both sports and healthcare domains, employing various devices, among which threshold devices are prominent. The aim of this study is to determine the relationship between inspiratory muscle fatigue and maximal inspiratory pressure, diaphragmatic strength (guided by ultrasound image) and heart rate variability. According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue in healthy youngs could influence cardiorespiratory function. In this study, subjects will be divided into three groups: the experimental group , the activation group and the control group. Measurements of variables, such as maximal inspiratory pressure, heart rate variability and diaphragmatic strength (ultrasound image), will be conducted.
Respiratory muscle training represents an effective method increasingly utilized in both sports and healthcare domains, employing various devices, among which threshold devices are prominent. The aim of this study is to determine the relationship between inspiratory muscle fatigue and muscular strength in lower limbs, in both healthy and pathological subjects, as well as the association between such fatigue and other variables, including maximal inspiratory pressure and muscle tissue oxygen levels. According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue in healthy youngs could influence muscular strength, exercise capacity and muscle tissue oxygenation. In this study, subjects will be divided into three groups: experimental group , activation group and control group. Measurements of variables, such as maximal inspiratory pressure, peripheral muscle tissue oxygen levels, diaphragmatic strength (ultrasound image) and vertical jump performance, will be conducted.

As part of the ageing process muscles become weaker. One of the reasons for this is that mitochondria, the 'engines' that provide energy to fuel muscles, age and work less efficiently. Mitochondria are found in almost all cells in the human body. Mitochondria take in nutrients that are provided from food and break these down to create energy-rich compounds to fuel many different processes in the body. Muscles are loaded with mitochondria because they require a lot of energy. Mitochondria naturally produce small compounds called oxidants that can damage muscle cells and can cause inflammation. The cells in the body have a natural defence system to protect against oxidants, but when mitochondria age and become less efficient, the amount of oxidants that they produce can increase. These oxidants can damage muscles and the mitochondria themselves. Antioxidants, such as vitamin C, may help protect muscles from the damage caused by oxidants, and may help mitochondria work more efficiently. In this study, the investigators will explore whether vitamin C can help mitochondria work more efficiently, which may improve muscle strength, and help older people to remain mobile and independent for longer.
The purpose of this study is to investigate the effective connectivity between different regions of the human brain in healthy participants, and the mechanisms which influence and modulate its development. Specifically, the investigators will examine the effects of cortico-cortical paired associative stimulation (ccPAS) which is induced by the application of brief (< 1 ms) transcranial magnetic stimulation (TMS) pulses separated by a short millisecond-level time intervals ("asynchrony") to two different areas of the brain. All techniques are non-invasive and considered safe in humans: TMS, electroencephalography (EEG), and magnetic resonance imaging (MRI). Based on previous animal and human studies, it is hypothesized that ccPAS will increase or decrease effective connectivity between the stimulated areas depending on the asynchrony value. The main outcome measure is source-resolved EEG cortico-cortical evoked potentials (ccEPs) elicited by single-pulse TMS.
This is a single-center, open, randomized, single-dose, two-cycle, two-sequence, crossover pharmacokinetic study in healthy adult subjects. The trial is planned to enroll 24 healthy subjects. Subjects will be randomized to one of two groups (Group A: T-R, Group B: R-T) according to the randomization table. The washout period (dosing interval) between doses will be at least 7 days. For example, for a washout period of 7 days, all subjects will receive the appropriate drug according to the randomized schedule on Day 1 of Cycle 1 and Day 8 of Cycle 2 of the trial.
