Filter by:The goal of this clinical trial is to learn about oxytocin ( a naturally occurring hormone made in the brain that transmits messages) and the effects it may have on thermal heat pain after intravenous administration. The main question it aims to define is the time course of change in pain score after a 5 minute heating of the skin administered at intervals during and following infusion of intravenous oxytocin in order to create a Pharmacokinetic and a Pharmacodynamic model for oxytocin-induced analgesia. Participants will be asked to rate thermal heat temperatures before, during and after the intravenous infusion of oxytocin.
The study medicine NNC0194-0499 is under development for non-alcoholic fatty liver disease (NAFLD) including non-alcoholic steatohepatitis (NASH). All participants will receive a single dose of 30 milligram (mg) of the study medicine. The study medicine will be given in the form of an injection of 0.6 millilitres in a skinfold of the thigh (subcutaneous). The study will last for up to 64 days. Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period. Women who are able to become pregnant must use highly effective contraception and will be counselled on the use of contraception. Participants with impaired liver function will undergo an ultrasound of the belly and measurement of brain activity.
In the present project, the investigators aim at proposing innovative ways of investigating spinal motoneuron hyperexcitability to counteract the associated impairments by using wide pulse high frequency neuromuscular electrical stimulation (WPHF NMES) in various populations. The investigators will use WPHF NMES contractions as a model to gain insights into the mechanisms underlying muscle cramps, restless legs syndrome or stroke-induced spasticity as there is evidence that they share common underlying mechanisms. The investigators will then use WPHF NMES as a training modality to improve plantar flexor neuromuscular function in stroke patients by taking advantage of their motoneuronal hyperexcitability.
The goal is to study the direct effects of long-term intermittent fasting on immune cell populations in the blood, combined with analyses of systemic metabolic fitness and inflammatory activation of leukocytes.
This is a Phase I, first-in-human, single-center, randomized, double-blind, placebo-controlled, single ascending dose study to evaluate the safety, tolerability, and PK of ascending doses of CBP-4888.
[14 C] Mass balance clinical trial of TY-9591 in healthy Chinese subjects
The purpose of this study is to confirm there is no significant effect of gastric pH changes of famotidine on the drug levels of afimetoran in healthy participants.
Numerous studies have shown that the extra-cranial application of near infrared light (λ=600-1000nm) (also called transcranial photobiomodulation or tPBM), has a positive impact on brain function in both humans and experimental animal models and a neuroprotective effect in animal models. Several of these studies have reported that tPBM could impart more beneficial effects in aged or diseased brains. The primary objective of this study is to use fMRI to compare the cerebral activations in response to a finger tapping motor task, before and after 24min of tPBM versus sham stimulation, in old and young healthy human subjects. The hypothesis of the investigators is that tPBM improves brain function in participants who will be treated using the active device in comparison with those treated with the sham device and that this effect should will be more pronounced in the older subjects.
Anorexia nervosa is characterized by intestinal dysbiosis, related to the feeding behavior impairment presented by these patients. Pathophysiologic hypotheses are involving the trouble of the microbiota-gut-brain axis in the field of mental diseases.
Participants with respiratory disease experience often a worsening of their condition, with increasing symptoms such as cough and shortness of breath. This worsening, often called exacerbation or flare up, impacts on the life of the participants, since they become limited in their daily activities. Healthcare is still based today on limited times for clinical appointments to perform investigations and to meet with specialists/clinicians. Very often, these evaluations do not reflect the way the disease is limiting the patient's life. Wearable devices offer the opportunity to collect data on physical activities and important clinical parameters (such as how the patient is active or just staying in bed during the day), on a daily basis. The HG Phoenix AI- based Smart Watch produced by Health Gauge, an Albertan company based in Edmonton, has the potential to measure heart rate, heart rate variability, blood pressure, pulse wave velocity, respiratory rate, temperature, arterial saturation, sleep pattern (deep, light sleep, awake time), duration and time, daily physical activities (site count and distance) and calories burnt in a simple and non-invasive fashion. Ideally, these parameters could be monitored and recorded 24 hours per 7 days per week. This study aims to demonstrate that this device can be used for a long time at home and it is comfortable to use for the participants, that it is not dangerous and, possibly, that it can help to identify exacerbations before the currently available investigations.
