Filter by:Skeletal muscle plays a critical role in supporting human health. Beyond its role in providing the force to move, skeletal muscle accounts for a large proportion of metabolic rate, glucose disposal, and amino acid storage. Skeletal muscle is dynamically regulated by environmental stimuli, such as loading (i.e., resistance training]) and unloading (i.e., disuse atrophy) as well as the intake of essential amino acids (EAAs). However, the precise mechanisms that regulate skeletal muscle mass in response to various conditions (e.g., EAA supplementation, resistance training, and unloading) are not completely understood. Therefore, concerted efforts to better understand the mechanisms regulating skeletal muscle size are needed that aid in the development of therapeutic interventions to combat age, disease, and disuse related muscular atrophy.
This is a Phase I, randomized, subject-blinded, placebo controlled study to assess the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD),and food effect (FE) of HSK39297 following (1) a single ascending dose (part 1), (2) 10 days of multiple ascending dose (part 2), and (3) a single dose two-period crossover FE cohort.
The purpose of the study is to look at how various tablets of a study medicine called vepdegestrant are processed in the body. This will be studied in healthy adult participants after food. This study looks at how the medicine is changed and removed from the body after a participant takes it. This study is seeking for participant who: - are healthy males, and healthy females who do not have the possibility to have children. - are 18 years of age or older. - weigh more than 45 Kilograms (99 pounds). The study consists of 3 treatments. Each participant will be assigned by chance to receive the 3 treatments in a certain sequence. This will be done over 3 study periods. Each treatment consists of a single amount of vepdegestrant taken by mouth in each study period. There will be a washout period between each study periods. The washout period is the time allowed for the medicine to get washed out from the body. How the medicine was processed will be calculated following each dose in each period. The total study duration is about 13 weeks.
There are no previous studies of the effects of a combination of whole-body immersions in hot and cold baths on adaptive responses and health-related markers. Thus, the primary aim of this project is to determine whether interventions consisting of whole body immersion in hot and cold baths over 16 days develop heat and/or cold adaptation by remodeling thermoregulatory, metabolic, cardiovascular and physiological responses, and the secondary aim is to determine if current cold-hot acclimation has any effects on physical and mental health-related markers.
Rare and very rare neurological diseases primarily or exclusively affect the nervous system with a prevalence of < 5 out of 10'000 and 100'000 people, respectively. Besides these, there are undiagnosed neurological diseases: neurological conditions without a diagnosis after completing a full diagnostic examination. Rare, very rare, and undiagnosed neurological diseases are complicated and progressive and often cause variegated motor signs, impairments, and syndromes. Balance and gait are frequently affected in these conditions, already at the clinical examination. These balance and gait impairments limit activities and cause an increased risk of falling. Falls can eventually result in injuries, even severe. There are only a few studies about these diseases, likely because of their rarity. Hence, the clinical presentation and the course of rare and very rare diseases are poorly known or even unknown. Essential information for these conditions' diagnosis, prognosis, treatment and rehabilitation is missing. MaNeNeND is an observational study underway at the Fondazione IRCCS Istituto Neurologico "Carlo Besta" (Milano) aimed at detailing the clinical and biological features of very rare and undiagnosed neurological diseases. Research questions: 1. Do patients with rare (Ra), very rare (V) and undiagnosed (U) neurological diseases suffer a balance and gait impairment? 2. Is there a correlation between the clinical and instrumental severity of the balance and gait impairment in RaVU neurological diseases? 3. Are instrumental measures more sensitive in detecting balance and gait impairments in patients affected by a RaVU neurological disease than the clinical measures? 4. Do the balance and gait impairments in RaVU neurological diseases worsen in time? The current project aims at diagnosing, quantifying and detailing the balance and gait impairment in rare, very rare and undiagnosed neurological diseases. To this aim, questionnaires, clinical scales and instrumental tests will be administered to these patients to collect a wide range of balance and gait measures. These measures will also integrate those collected with MaNeNeND to provide a more detailed description of patients with rare, very rare and diagnosed neurological diseases. Participants will complete two questionnaires: the Dizziness Handicap Inventory - short form (DHI-sf, an ordinal score of self-perceived balance) and the Modified Fatigue Impact Scale (MFIS, an ordinal score of self-perceived fatigue). Moreover, a clinician will administer the Mini Balance Evaluation Systems Test (Mini-BESTest, an ordinal score of balance), the 10 m walking test (for measuring the gait speed and other gait parameters) and the Timed Up and Go test (an instrumental measure of mobility and balance). Walking and the Timed Up and Go tests will be recorded with a trunk-worn inertial measurement unit. Finally, participants will be asked to complete an instrumental upright stance and gait assessment, the first consisting of standing on posturographic plates and the second of walking on a treadmill equipped with force sensors. When walking on the treadmill, an optoelectronic system will also record the position in time of limbs and trunk. The quantification of the severity of the balance and gait impairment of the patients suffering a rare, very rare or undiagnosed neurological disease will highlight these persons' therapeutic and rehabilitative needs. Comparing the balance and gait impairment of rare, very rare and undiagnosed diseases with those of multiple sclerosis, Parkinson's disease and peripheral neuropathy will highlight if the formers' balance and gait impairment has unique characteristics that could help ease the diagnosis of these uncommon conditions. The longitudinal measurements on rare, very rare and undiagnosed diseases will be paramount to identifying prognostic factors. In addition, the data collected in the current study will be crucial for future studies, for example, for estimating the sample size in clinical trials.
There is some clinical evidence showing that Baduanjin (BDJ) practice, a type of mind-body based physical exercise, can improve executive function (EF). However, the neurophysiological changes associated with improved cognitive function remain elusive. Therefore, this study aims to carry out randomised controlled trial to explore how the single-session BDJ practice affect the function of prefrontal cortex(PFC) and also the EF of healthy adults, measure by fNIRS and verbal fluency test accordingly. A total of 60 healthy adults (based on power analysis 80% (β= 0.20) chance (α = 0.05, two-tailed)), aged 18 to 40 year old, without any physical, neurological, and neuropsychiatric disorder, classified as right-handed by Edinburgh Handedness Inventory, also with normal intelligence as verified by the Test of Nonverbal Intelligence will be recruited and randomly assigned to treatment(i.e. BDJ), active control(i.e, exercise), and passive control(i.e. video viewing) group. The investigator anticipate that this single-session BDJ practice will result in - (1) enhancing executive functioning , and (2) changes in functional brain activation pattern in PFC in adults. The result will give a spotlight to neurophysiological treatment effect of single-session Baduanjin on healthy adults, in developing intervention for improving executive functioning of adults.
This interventional study aims to test the effects of sleep disruption on pain sensitivity and biomechanics in healthy individuals during experimental knee and shoulder pain. The main question the study aims to answer is: 1) Does sleep fragmentation increase experimental knee and shoulder pain and what are the underlying mechanisms? Participants will receive two injections a) Hypertonic saline (painful) in the knee and b) hypertonic saline (painful) in the upper arm.
The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will - ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time - ingest a soluble form of oxalate and sugar preparations to test gut permeability - collect urine, blood, stool and breath sample during the fixed diets and the soluble oxalate test
The aim of this study was to investigate the effects of different concentric and eccentric muscle fatigue protocols on the knee joint position sense of healthy individuals.
This interventional study aims to test gait biomechanics in healthy individuals with and without experimental knee pain. The main questions it aims to answer are: - How do gait patterns change during painful walking? - Can pain sensitivity testing and gait biomechanics predict experimental knee pain intensity? Participants will receive two knee injections: a) Hypertonic saline (painful condition) and b) Isotonic saline (control condition).
