This is a Phase 1, FIH, randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, PK and PD after SAD and MAD in healthy adult participants. Read Less

The investigators currently lack an understanding of barriers to completing the male factor infertility evaluation. Furthermore, as the investigators continue to expand access to fertility treatment particularly within low-resourced settings, it is important that all aspects of infertility within a couple are equally explored. The COVID-19 pandemic has disproportionately affected low-income communities and communities of color at greater rates in terms of not only disease morbidity/mortality but how medical systems are accessed and care is delivered.

The study will compare gene expression differences between blistered and non-blistered skin from individuals with all subtypes of EB, as well as normal skin from non-EB subjects. State of the art computational analysis will be performed to help identify new drugs that might help all EB wound healing and reduce pain. Researchers will focus on drugs that have already been approved for treatment of other dermatologic or non-dermatologic diseases, and therefore be repurposed for treatment of EB. Drug development is a very expensive process taking decades for execution. Drug repurposing on the other hand, significantly reduces the cost and shortens the amount of time that is needed to bring effective treatments to clinical use. To date, there is no specific treatment targeting the physiology and immunologic response in EB patients during wound healing. Market availability of repurposed medications will provide all EB patients rapid access to treatments, thus improving their quality of life. Read Less

The primary objective is to evaluate the laboratory safety of Ashwagandha standardized root extract 500 mg capsules in healthy adults over 12-week therapy based on Complete Blood Count, Renal Function Test, Liver Function Test, Lipid Profile and Thyroid Function Test, Fasting blood sugar and HbA1c Test. The secondary objectives are to evaluate the clinical safety of Ashwagandha standardized root extract 500 mg capsules in healthy adults over 12-week therapy and to evaluate the effect of the Ashwagandha standardized root extract 500 mg on Quality of Life (QoL) using the SF-36 tool.

There is reason to believe the current dietary reference intakes for dietary protein for children are too low. Furthermore, children with high levels of physical activity and fitness may require a higher requirement. To better understand the protein requirements in minimally and highly physically fit and active children 8-10 y old, investigators will use the indicator amino acid oxidation technique. Read Less

The purpose of this study is to evaluate the Genesis Electrical Impedance Tomography (EIT) imaging system for use in pediatric respiratory disease populations including neuromuscular and bronchopulmonary dysplasia, as well as in age and height matched controls. The EIT does not use radiation, and is read through electrodes. Read Less

Emerging evidence demonstrates that animals and people can exert control over the level of excitability in spinal and corticospinal neural circuits that contribute to movement. This discovery has important implications, as it represents a new strategy to improve motor control in people of all ability levels, including those with neurological conditions. Operant conditioning is a well-studied mechanism of learning, in which the modification of a behavior can be brought about by the consequence of the behavior, and reinforcement causes behaviors to become more frequent. In recent years, operant conditioning has been applied to spinally-mediated reflex responses in mice, rats, monkeys and people. By electrically stimulating a peripheral nerve, recording the muscle response, and rewarding responses that are within a desirable range, it is possible to increase or decrease the neural circuit's excitability. This may alter the level of resting muscle tone and spasticity, as well the muscle's contribution to planned movements and responses to unexpected events. Operant conditioning of spinal reflexes has been applied to a lower limb muscle in healthy people and those with spinal cord injuries. In this project, we will expand the use of operant conditioning to muscles of the upper limb, demonstrating feasibility and efficacy in healthy people and people post-stroke. We will determine whether operant conditioning can be used to decrease excitability of spinal reflexes that activate a wrist flexor muscle. Additionally, in a separate group of healthy people, we will determine whether operant conditioning can be used in a similar way to increase corticospinal excitability. We will stimulate the motor cortex with transcranial magnetic stimulation to elicit motor evoked potentials in the same wrist flexor muscle, and will reward responses that exceed a threshold value. We will examine the effects of these interventions on motor control at the wrist, using an innovative custom-designed cursor-tracking task to quantify movement performance. We will determine whether changes in spinal reflex excitability or corticospinal excitability alter motor control. The overall goal of this research is to develop a new, evidence-based strategy for rehabilitation that will improve recovery of upper limb function in people after stroke. Read Less

The goal of this clinical trial is to determine the effect of maximal mental effort combined with elastic band training on strength and neuromuscular function in healthy, older females. The main questions it aims to answer are: * Does elastic band training in combination with maximal mental effort increase strength more than elastic band training alone? * Does elastic band training in combination with maximal mental effort improve neuromuscular function more than elastic band training alone? Participants will be randomly assigned to 1 of 3 groups: * Elastic band training * Elastic band training with maximal mental effort * Control Researchers will compare groups to determine differences in changes in strength, neuromuscular function, and body composition.

Sedentary behavior has been linked to cardiovascular morbidity and mortality, and is particularly common in older adults with type 2 diabetes. The purpose of this observational, mixed-methods study is to better understand the relationship between prolonged sedentary behavior and cardiovascular and metabolic health in older women. Read Less

Expressive writing involves writing about one's deepest thoughts and feelings surrounding an emotional event. The current literature on the efficacy of expressive writing is mixed and warrants further investigation into how, when, and for whom expressive writing is an effective intervention. The goal of this study is to compare the efficacy of expressive writing interventions in young adults when people imagine that they're writing to themselves vs. a loved one. Participants will carry out an expressive writing exercise for 14 consecutive days. Participants are randomized into 3 groups: Self, Other, and Control. The Self group is instructed to write as if they were talking to themselves. The Other group is instructed to direct their writing to someone they feel close to. The Control group is asked to write down a factual description of their routine that day, and direct this writing to themselves. We will recruit participants until we have usable data from 53 participants per group (i.e., 159 in total). Read Less

Healthy adult subjects will participate in two sessions. The first session will involve measurements of brain activity using simultaneous recordings with electroencephalography (EEG) and functional Magnetic Resonance Imaging (fMRI). During brain activity measurement, participants will perform cognitive tasks assessing attention. The second will involve fMRI-based neurofeedback during simultaneous EEG-fMRI recording. Participants will receive real-time visual feedback of signals measured from specific parts of their brain and will try to control that activity. Read Less
