Filter by:The goal of this crossover study was to learn about the potential regulatory role of serotonin in interoceptive processing and its relationship to levels of state anxiety. This experiment directly compared the impact of a selective serotonin reuptake inhibitor (SSRI) (20mg CITALOPRAM) to that of a PLACEBO on the neural processing of ordinary interoceptive sensations and the relationship of these influences to anxious states. Healthy young volunteers completed the visceral interoceptive attention task with each treatment condition (citalopram and placebo). The task involves focusing attention on heart, stomach, or visual sensation control while scanned with functional magnetic resonance imaging (fMRI). The difference in haemodynamic response between interoceptive sensation(s) and visual sensation (i.e. the relative interoceptive response) is compared between treatment conditions. State anxiety is measured at each test period. It is used to test for a moderating effect of state anxiety on the influence of serotonin in interoceptive processing and used post-hoc to explore associations between changes in state anxiety and changes of interoceptive relative interoceptive response due to the SSRI.
Radial Extracorporeal Shockwave Therapy has been shown to restore shortened muscles and normalize fibrotic tissues in muscles or fascia. Shockwave therapy can soften fibrotic tissues and alleviate pain. While there are various methods to relax muscles and fascia, radial extracorporeal shockwave therapy can achieve good results in a short treatment time. Although there is research on the pain-related effects of radial extracorporeal shockwave therapy for conditions such as plantar fasciitis and knee osteoarthritis, there is a lack of literature on its functional effects. Therefore, this study aims to investigate the improvement of ankle functionality through the application of radial extracorporeal shockwave therapy.
Previous studies have shown that healthy individuals who take more steps per day and who spend more time on moderate- to vigorous-intensity activities exhibit better pain inhibition and less pain facilitation. Furthermore, exercise training (i.e., exercise performed over a number of sessions) can result in reduced pain sensitivity (increased pressure pain threshold). However, the optimal exercise prescription required to achieve pain sensitivity reduction is currently unclear. The next step is to determine experimentally whether increasing physical fitness will lead to positive effects on central pain processing (i.e., pain sensitivity, pain modulation, spinal nociception). The aim of this study is to examine the effects of two exercise programs on central pain processing in healthy sedentary individuals. In case of positive effects, this would provide a rationale for the future to investigate this in chronic pain patients with impaired pain modulation.
This study, based on preliminary experimental results, literature review, and expert consultations, developed the Attentional Rating Scale (ARS). The aim was to rapidly assess participants' attention and potential influencing factors. The research focused on the scale's reliability and validity among healthy adults. Additionally, the Attention Network Test (ANT) served as the gold standard for evaluating attention. The study attempted to identify correlations between various dimensions of attention and the three attentional networks.
The purpose of this study is to verify the immediate effects of Tissue Flossing on knee flexion range of motion
The goal of this open-label, placebo-controlled, dosage escalation study is to learn about the safety of a Cannabis/Hemp Isolate Extract in normal healthy adults engaged in elite contact sport competition. The main question it aims to answer is: • Are cannabis/hemp-based products with high CBD safe, well-tolerated and without adverse physiological and psychological dysfunction, when administered on a daily basis? Participants will: - be given CBD and a placebo. The placebo will be taken for 2 weeks prior to starting the CBD. Participants will start on a low dose of CBD, beginning at 5 mg CBD/kg body mass, which will be increased by 5 mg/kg every 2-weeks until 30 mg CBD/kg body mass is taken; - have blood samples taken to analyse how much CBD is used in the body and for how long it lasts in the body (pharmacokinetics and pharmacodynamics); - have saliva samples collected for genetic analysis; - undergo testing sessions, which will include psychological and health questionnaires, equipment to record signals from the brain and heart, and safety laboratory tests.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Charcot-Marie-Tooth disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for Charcot-Marie-Tooth disease.
According to the World Health Organization, physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. Positive effects of leading a physically active life and exercise have been shown in many areas ranging from diabetes to cardiovascular diseases, cancer to mortality, pain to autoimmunity .
Physical exercise, especially of high intensity, is a significant burden to the athlete's body. It should be emphasized that achieving high results in competitive sports requires significant, sometimes extreme, exercise loads during training, which may result in homeostasis disorders, adversely affecting athletes' fitness. Intense and prolonged physical exercise elevates reactive oxygen species, potentially impacting immune function. The mechanism, particularly in high-intensity activities, remains incompletely understood. Excessive oxygen radicals may induce metabolic changes, causing rapid erythrocyte damage and elevated redox-active free iron. This iron increase can be harmful, increasing oxidative stress and immune system activation. The sustained negative impact that may be observed even during post-workout recovery needs further exploration. "This study aims to explain the impact of an intense exercise test on the immune system, pro-antioxidant balance, and iron metabolism in athletes with varying training levels. The primary questions it seeks to address are: 1. How do athletes' experience and training background influence the immune system's response, pro-antioxidant balance, and iron regulation? 2. Can the level of adaptation to physical exercise (training status) affect the rate of regeneration and the time required to return to pre-exercise homeostasis?"
This is a single-dose, single-center, open-label, randomized, 2-way crossover study (2 treatments, 2 periods and 2 sequences) of a buccal formulation of Nalmefene 16 mg and a 1 mg intravenous dose of nalmefene injection, with a least 7 days washout period between doses.
