The purpose of the study is to determine the effects of amiloride on the blood pressure response to walking in PAD patients and healthy controls.

In each visit, you will be asked to walk on a treadmill. You will also be asked to take capsules prior to visit 2 and 3. The capsules for one visit will be a drug called amiloride (10mg, in 2 capsules with 5mg of amiloride in each capsule), which was traditionally used to lower blood pressure. The other capsules will be a placebo (no active medication). A blood sample will be drawn at each visit.

The purpose of this study is to survey hearing aid users over a 6 month time period to see if their music perception improves over time.

Study participants will complete surveys about their music experience four times: first at your initial clinic visit and then sent to your email at 1, 3, and 6 months following your visit. This survey will include questions about the participants experience with music as well as name, age, gender, and duration of hearing aid use.

The study will compare participants with primary central nervous system lymphoma which responded to initial treatment and are thereafter treated with Obinutuzumab (the study drug), with participants with primary central nervous system lymphoma which responded to initial treatment and are not treated with the study drug.

In addition to your routine care, you will be “randomized” into one of the study groups described below. You will have a MRI of your brain approximately every three months (plus or minus two weeks) for two years. You will undergo a neurocognitive assessment and complete a quality-of-life questionnaire two years after study entry. Group A – Obinutuzumab Arm If you are in the first group ("Group A") you will be given the study drug every two months for two years. Every two months you will have your vital signs taken, your blood drawn (one to two tablespoons), and you will be given the study drug through an IV infusion into your vein. Group B – No Obinutuzumab Arm If you are in the second group ("Group B") every six months you will have your vital signs taken and your blood drawn (one tablespoon).

To compare time to ctDNA (+ve) status in ctDNA (-ve) cohort following resection of stage III colon cancer treated with immediate vs delayed (based on serial ctDNA surveillance) chemotherapy. Time to positive event is defined as time from randomization to the first ctDNA positive result for the immediate arm (Arm 1) and to the 2nd ctDNA positive result for the delayed arm (Arm 2) to allow for the potential effect of delayed adjuvant chemotherapy. Patients recurred without a positive ctDNA result will be considered to have ctDNA positive status at the time of recurrence for both study arms.

We are asking you to take part in this research study because you have colon cancer that has been treated with surgery but has spread to some of your lymph nodes and is known as stage III colon cancer. Or, you have stage II or stage III colon cancer with a higher risk of cancer returning, your colon cancer has been treated with surgery, and you had ctDNA testing done and are ctDNA positive. Stage II colon cancer is an early stage colon cancer that has been treated with surgery but has not spread to your lymph nodes. ctDNA, or circulating tumor DNA, is DNA that has been released from tumor cells into your bloodstream. This DNA can be measured using a blood test.

People with narrowed blood vessels in their legs can only walk a short distance before needing to sit down due to pain in their calf muscles. Most of these patients do not follow their heart doctor's advice to walk at home because it hurts. A therapy that does not involve painful walking would be ideal for these patients to begin to treat their disease so they can eventually walk with less discomfort. We will ask patients with peripheral artery disease (PAD) to place both feet into inflatable ankle splints 30 minutes a day for 4 weeks to passively stretch their calf muscles. Before and after this 4-week program, we will measure the health and size of their leg blood vessels, the length, and function of their calf muscles and tendons, and how long they can walk without pain. We will also closely track their joint and foot movements and calf muscle oxygen levels while they walk down a hallway. People with and without risk factors for heart disease are also eligible for this study to compare differences in vascular and muscular health to patients with PAD. Volunteers without a PAD diagnosis or poor leg circulation will not undergo the 4-week stretch and no-stretch interventions.

Peripheral artery disease (PAD) and poor leg circulation patients: -4 visits to University Park Clinical Research Center ~3 hours per visit -1 blood draw -Wear a calf muscle stretching device for 30-min a day, 5 days a week, for 4 weeks and 4 weeks of no stretching -Several muscle and vascular ultrasound measurements -Walking performance tests on and off the treadmill -Wear a smartwatch to monitor physical activity during each 4-week stretch or no stretch intervention Participants with and without risk factors for heart disease: -2 visits to University Park Clinical Research Center within the same week lasting ~3 hours per visit -Not diagnosed with PAD or poor leg circulation -1 blood draw -Several muscle and vascular ultrasound measurements -Walking performance tests on and off the treadmill

PAD participants can receive up to $450 in compensation. Participants with and without heart disease risk factors (non-PAD participants) will receive $50 for their participation.

The goal of this study is to understand how babies and their mothers learn to respond to stress during the early years of the baby's life. Participating women complete questionnaires and do a mildly stressful task alone (during pregnancy) or with their babies (at four different times over the first two years of the baby's life) and collect saliva samples that tell us about stress responses, either at home or at one of our lab sites. We aim to use what we learn to better support expecting parents who may be at risk for stress-related health problems and improve their children's resilience to stress throughout life.

Women are asked to participate in six sessions over Zoom and/or at the PACT Center between their 28th week of pregnancy and when their child is 2 years old. During these sessions, which last up to 2 hours each, mothers and babies will 1. participate in mildly stressful tasks (like having the mother leave the room for up to 3 minutes and then return) and games to assess the baby’s emotional and cognitive development 2. provide saliva samples by drooling into a tube (for the mother) or holding a cotton swab in their baby’s mouth to get it wet 3. fill out questionnaires about themselves and their baby 4. take part in clinical interviews that ask about mood and other markers of psychological ill-being

Adolescence is a critical period during which many important healthhttps://irb.psu.edu/IRB/sd/ResourceAdministration/Project/ProjectEditor?Project=com.webridge.entity.Entity[OID[058ACDEB3E43384D816C7E390C2B83F6]]&Mode=smartform&WizardPageOID=com.webridge.entity.Entity[OID[E4552FC57E491543A6B7FD8268E23FD7]] habits form in humans. However, animal models provide mixed information about habit formation across development and there are relatively few human studies that address differences between habit formation in adolescents and adults. To address this gap, the proposed study will assess differences in habit formation in adolescents and adults as measured by the "Slips of Action" task, which seeks to discriminate between habitual and goal-directed learning of visual stimuli pairings.

There will be one in-person visit lasting about one hour. Visits will begin with informed consent. Participants will complete a computer task where they are asked to learn associations between pictures and then will be tested on the associated pairings. They will also complete questionnaires and cognitive tasks.

To compare overall survival (OS) in patients with inoperable, early stage non-small cell lung cancer (NSCLC) randomized to stereotactic body radiation therapy (SBRT) with or without atezolizumab.

Patients will need to keep all of their radiation treatment appointments and keep all appointments with the study doctor. Patients will be expected to complete questionnaires and have extra blood samples taken at specific time point throughout the study.

We are investigating how the starch from pulse crops (chickpeas, lentils and dry peas) affects the gut microbiome, particularly with regards to the production of butyrate, a microbial metabolite with a number of known health benefits. We are recruiting people from two groups, those that consume a lot of these pulses and those who rarely consume them. These participants will then track their food intake for 48 hours before collecting a fecal sample which they will return to the lab. We will then use these fecal samples to conduct laboratory fermentations with pulse starches processed in a number of different ways to see what factors are important for determining the amount of butyrate that is produced. This will serve as pilot data for designing future human clinical trials.

We wish to investigate the role of a specific gene in visceral pain sensation and perception. This gene, Nav1.8 has a known change present in 10% of the population which may affect the way we feel inflammatory pain in the gut. This is an important symptom in inflammatory bowel disease (IBD). Some patients feel high levels of pain we would like to control, other patients feel little to no pain in the presence of very active disease, which can lead to dangerously under-treated disease. In this study, we will use healthy volunteers as well as IBD patients, and test their sensitivity using rectal balloon dilation. Research subjects will be asked to fast, skipping solid foods and opaque liquids for 6 hours before the testing. Usually this means skipping 1 meal. At the beginning of the study visit. they will use an over the counter enema to clear their rectum of any stool. Healthy control subjects that have never had a colonoscopy before and all IBD patients will undergo a very brief proctoscopy to either verify rectal health or check for any IBD disease activity. Healthy controls that have had a prior colonoscopy within the last 5 years will skip that prior step. Then a trained physician on the research team will insert a thin, lubricated tube into the rectum, which will be inflated to specific pressures. Most of these tests will be designed to measure any change in sensation, then the need to use the toilet, followed by urgent need or discomfort, and lastly the lower threshold of pain. Test subjects will be able to stop testing at any time, should they become too uncomfortable. The testing takes between 1 and 1 and a half hours, and volunteers are compensated $200 for their time.

To simulate abdominal pain, we use a thin tube placed in the rectum that inflates a small balloon to very precise and safe pressures. Our bodies interpret these pressures (in ascending order) as the need to go to the bathroom; first just a little, then with increasing urgency and eventually discomfort and pain. During these experiments, we only measure the lower threshold of pain, and stop immediately when you tell us to stop. We have significant experience using this approach and we have found it consistently informative while causing the least amount of discomfort possible. The whole thing takes about an hour and we’re paying volunteers $200 for participating. We'll ask that you skip a meal before the study visit, and perform an over-the-counter enema at the start of the visit.

This is dietary intervention trial that will examine the impact of consuming three different types of resistant starch on the gut microbiome and butyrate levels in normal weight and obese individuals. Participants will consume starch samples daily for 24 weeks, collecting weekly fecal samples that will be returned to the lab. Researchers will analyze the bacterial fermentation products in these samples, particularly butyrate and analyze the microbiome composition. This will allow identification of differences in resistant starch (a dietary fiber) processing between normal weight and obese individuals and will also determine if the three resistant starches tested have differing impacts on the microbiome and butyrate levels.

The purpose of this study is to compare the usual treatment of chemotherapy and radiation to adding MEDI4736 (durvalumab) immunotherapy to the usual treatment. The addition of MEDI4736 (durvalumab) immunotherapy to the usual treatment may help shrink your cancer better than the current standard of care or usual approach for bladder cancer. But, it could also cause side effects, which are described in the risks section. This study will help determine if this different approach is better than the usual approach. To decide if it is better, the study doctors will be looking to see if the study approach increases the life of patients by 6 months or more compared to the usual approach.

If you decide to take part in this study, you will either get chemotherapy and radiation for 6-8 weeks, or you will get durvalumab immunotherapy in addition to chemotherapy and radiation for 6.5-8 weeks. After you finish your study treatment, your doctor will continue to follow you for up to 3 years. The follow-up will consist of visits to his or her office and CT scans of the bladder.

There is a growing body of data demonstrating that polyphenols from foods including cocoa and chocolate are metabolized by the gut microbiome to produce small molecular weight metabolites that have greater systemic bioavailability and a potential role in the health-related effects of the parent compounds. The objective of this protocol is to collect fecal samples from human subjects, aged 18 - 40 years old, with overweight or obesity (BMI = 25 – 40 kg/m2), to use as a source of gut microbiota. These fecal samples will be used in in vitro fermentation experiments where fecal samples will be mixed cocoa powder or cocoa extracts in buffer. Samples from these fermentation experiments will be analyzed by chemical methods to identify the metabolites present and will be tested in bioassays to determine potential health-related bioactivities. Because biological sex can impact the composition of the microbiome, we plan to recruit both biological males and females.

There will be two in-person visits. Screening and consent collection will be done at the first and participants will receive supplies for stool collection. The participant will collect the stool samples at home and then return the sample at the second visit.

In addition to using the application, participants will be asked to complete 3 check-in phone calls through-out the 8 weeks.

Up to 50 older adults (age 60+ years) will participate in a two-visit CRC study with blood sampling (40 ml per visit) occurring before and after a breakfast meal. Specifically, there will be four (10 ml) blood draws during each of the visits, with each blood draw timed one hour apart (T1 to T4). The two visits (short- and long-fasting) will be randomly assigned and counterbalanced for the order in which they occur and will occur at least a week apart. During the short-fasting visit, participants will arrive fasting and be given breakfast after the second blood draw (T2). During the long-fasting visit, participants will arrive fasting and be given breakfast after the fourth blood draw (T4). Aside from blood draws, and vitals obtained at the start of each visit, participants will be seated comfortably in a chair in a small room by themselves. They will be checked upon periodically to ensure they are not falling asleep, they are comfortable, etc. They will also be given a small packet of written questionnaires to complete after T1 and after T3 (i.e., after the 1st and 3rd blood draws). Each visit will be between 3.5 and 4 hours.

There will be two in-person visits both will include four blood draws.

Patients will be expected to come to the clinic for all radiation treatments and all chemotherapy treatments.

The purpose of this study is to compare the usual approach of chemo/radiation followed by one year of MEDI4736 (durvalumab) to chemo/radiation with MEDI4736 (durvalumab) followed by one year of MEDI4736 (durvalumab). The addition of MEDI4736 (durvalumab) during chemo/radiation could prevent your cancer from returning and extend your life. But, it could also cause side effects. This study will help the study doctors find out if this different approach is better, the same, or worse than the usual approach. To decide if it is better, the study doctors will be looking to see if the study drug extends the life of patients and/or prevents the tumor from coming back as compared to the usual approach. This drug, MEDI4736 (durvalumab), is already approved by the FDA for use in other cancers, and for use in your type of cancer after the completion of chemotherapy and radiation. At this time MEDI4736 (durvalumab) is not yet approved (experimental) when given with chemotherapy and radiation. There will be about 660 people taking part in this study.

The overall goal of this proposal is to develop robots that can help people correctly calibrate their trust in the robot. We look at this problem within the context of robot-guided emergency evacuation. We believe that robots stationed inside of buildings can serve as instantaneous first responders helping people safely evacuate during an emergency, thus saving lives. Participants will be asked to interact with an emergency guidance robot and decide whether to follow the robot to an exit.

This study will follow symptomatic ALS participants and control participants for 2 years, measuring a wide range of ALS outcome measures and gathering long term survival data.

Study visits will be conducted both in an in-clinic setting (on-site) and remotely (off-site) over the course of 24 months (2 years). The symptomatic ALS cohort participants can either participate in on-site or off-site visits, depending on their location and ease of access to one of the participating sites. During this 2-year period, symptomatic ALS participants will complete a screening visit (2-3 hours to complete), a total of 7 in-person study visits (1-3 hours to complete) and 24 remote self-assessment activities (completed each month, takes 35-45 minutes to complete). Participants and will need access to a personal device (i.e. a computer and/or smartphone or tablet) and an internet connection to participate in this study. All control participants will participate on-site, completing their on-site visits every 12 months. Biospecimens will be collected at regular intervals to support biofluid biomarker analyses. Biospecimens will include plasma, serum, whole blood for generation of induced pluripotent stem cells (iPSCs) and DNA for whole genome sequencing, and cerebrospinal fluid (CSF). For on-site symptomatic ALS and control participants, CSF will be collected through optional Lumbar Puncture (LP) procedure. Only plasma, serum and whole blood will be collected for off-site participants through home phlebotomy collection process.
