This trial is designed to develop and test the efficacy of cognitive training strategies to improve self-regulatory capacities for middle-aged adults to adopt and sustain a physically active lifestyle. The main questions it aims to answer are: * Can cognitive training designed to improve cognitive control improve physical activity adherence? * What are the psychological, physiological, cognitive, and sociodemographic factors that affect the impact of cognitive control on physical activity adherence? Participants will * Complete a 6-week home-based, computerized cognitive training program * Complete a 6-week home-based, aerobic exercise training program with supervision of a health coach and trainer * Complete a 6-week home-based, aerobic exercise training program prescribed by a health coach and trainer * Visit the laboratory before and after cognitive training, and before and after physical training, to complete assessments of cognition and aerobic fitness Read Less

This study aims to examine the effect of force levels in orthodontic treatment during canine retraction. Force levels refer to the pressure applied by the orthodontic devices to move teeth. Data collection will include gingival fluid, dental molds from a digital scanner, and x-rays of the upper canine region on both sides of the mouth during treatment. The null hypothesis to be tested is that there is no significant difference in the rate of canine movement between the light force and the heavy force levels. Read Less

The purpose of this study is to learn about the safety of islet transplantation when performed after kidney transplantation, which may provide more normal control of blood sugar without the need for insulin shots. Islets are special clusters of cells within the pancreas that produce insulin. These cells will be obtained from cadaver (non-living) donors and given to subjects by vein. Read Less

Participants in this study will either have heart failure (HF) and are scheduled to undergo pace maker (PM) implantation, cardiac resynchronization therapy pacemaker (CRT-P), cardiac resynchronization therapy defibrillator (CRT-D) implantation, His bundle pacing (HIBP) or left bundle area pacing (LBAP) (including HIBP/LBAP for patients with HF, for patients who have failed CRT implant or patients who are CRT non-responders), or have atrioventricular (AV) block or bradycardia and are scheduled to undergo dual chamber pacemaker implantation. In this study additional heart rhythm measurements will be collected during the implant procedure to better understand how His bundle and/or parahisian pacing (HISP) effects electrical conduction in the hearts of patients with HF or AV block. The hypothesis is that His bundle or parahisian pacing (HISP) and left bundle area pacing (LBAP) may normalize atrioventricular (AV) conduction with a narrow combination of the Q wave, R wave and S wave (QRS complex) in functional bundle branch block or conduction delay in patients with heart failure (HF).

The purpose of this study is to evaluate OBT076, which is a drug that combines an antibody with an anti-cancer drug. This class of drugs are called Antibody-Drug Conjugates (ADC). Antibodies are normally produced in the human body by the immune system to fight infections but can be designed to target cancer cells and deliver an anti-cancer drug. OBT076 is composed of an antibody that targets the CD205 protein on cancer cells and delivers an anti-cancer drug which can kill them. OBT076 is an "Investigational Drug", which means that it is still being studied and has not yet been approved by the US Food and Drug Administration (FDA), the European Medicines Agency (EMA) or any other regulatory authorities to be prescribed by doctors for the treatment of metastatic or recurrent solid tumors. The use of OBT076 in this study is investigational. This is a Phase I research study designed to look at several dose levels of the study drug to find the highest dose level that is safe and well-tolerated (does not cause unacceptable side effects), and to examine the effects of the study drug in a small group of research participants. The study will also look at the effectiveness of OBT076 as an anti-cancer therapy. Once the optimal dose is determined and safety is assessed, additional research participants will be treated at the optimal dose level to further evaluate safety and effectiveness. Read Less

Parkinson's disease (PD) is characterized by many non-motor symptoms that occur several years before the diagnosis, in particular idiopathic REM behavior disorder (iRBD), which is associated with autonomic impairment. The purpose of this study is to investigate the effect of treatment with the selective post-synaptic a1-adrenergic blocker terazosin on 123I-MIBG myocardial uptake in a population of subjects with defined pre-motor PD risks (i.e. hyposmia and RBD) and abnormal baseline 123I-MIBG uptake, with or without 123I-Ioflupane uptake abnormality or PD motor symptoms. Scintigraphic changes will be correlated to motor and non-motor severity of PD, measured by validated clinical scales and cardiac autonomic function tests. Read Less

This is a Phase 1b open-label, multicenter study, evaluating the safety, tolerability, preliminary clinical activity, pharmacokinetics (PK), and pharmacodynamics of ZN-c3 in combination with other drugs. Read Less

The purpose of this study is to assess the efficacy of the combined interventions, Skills Training in Affective and Interpersonal Regulation (STAIR) and Parent-Child Interaction Therapy (PCIT) or P-STAIR, for treating maternal PTSD and reducing maltreatment recidivism. Read Less

Background: The ability to treat early prostate cancer is still limited. Thermal ablation methods are being tested for focal prostate cancer therapy. Researchers want to improve on these methods. Objective: To understand if Transurethral UltraSound Ablation (TULSA) in combination with MRI guidance is useful to treat localized prostate cancer. Eligibility: English-speaking adults ages 18 and older with localized prostate cancer that can be seen on MRI and can be treated by thermal ablation. Design: Participants will be screened with the following: * Medical history * Physical exam * Digital rectal exam * Blood and urine tests * Electrocardiogram * Tumor biopsy * Questionnaire to assess urinary tract symptoms * MRI of the pelvis. The MRI scanner is a long, narrow tube. Participants will lie on a bed that moves in and out of the scanner. Participants may also be screened with the following: * Echocardiogram * Chest x-ray * Bone scan * Urodynamic studies to see how well the bladder, sphincters, and urethra hold and release urine * MRI of the brain * Transrectal ultrasound * Computer tomography (CT) scan of the chest, abdomen, and pelvis. A CT scan is a series of x-ray images taken of parts of the body. Some screening tests will be repeated during the study. Participants will have the TULSA procedure. They will have an MRI for guidance. A small ultrasound applicator will be placed into their urethra. It uses heat to destroy the cancer areas in the prostate. It is controlled by a robotic arm. A cooling catheter will be placed into their rectum. Participants will use a urethral catheter for 1-7 days. Participants will have follow-up visits at 3, 6, 12, 18, 24, and 36 months. Read Less

Healthcare workers and COVID-19 patients may experience psychological distress consequent to the pandemic, and are at particularly elevated risk for experiencing posttraumatic stress disorder (PTSD), based on evidence from previous infectious disease outbreaks. The best-validated treatment for PTSD is exposure therapy. Exposure therapy help patients suffering from PTSD to revisit and overcome their traumatic experiences. Including virtual reality in exposure therapy has a long history in treating PTSD; and has been used to treat military veterans and first-responders following 9/11. The investigators are developing and testing a virtual environment to treat PTSD including sub threshold PTSD symptoms in HCWs who experience occupational related trauma (e.g., working with COVID-19 patients) and COVID-19 patients. An independent evaluator will assess symptoms of PTSD and other psychopathology, using structured clinical interviews and self-report measures with well-established psychometric properties, at baseline, halfway through treatment, after completion of treatment, and at three-months post-treatment. Participants will complete ten ninety minute sessions (in-person or remotely), twice a week for five weeks aimed at mitigating their symptoms of PTSD. Remote participants will receive VR headsets after the baseline assessment and will keep them for the duration of the study. The pilot study will aim to demonstrate the feasibility and the tolerability of the virtual reality intervention in these populations. Read Less
