Social network site (SNS) use has been very integrated into our daily practices. The distinctions between offline and online social relationship management become blurred with the mediation of SNSs. We are interested in how people perceive and use SNS and engage in social relationship management, such as self-disclosure or privacy management. Users may appropriate technological features to meet their own needs and such practices may be different from how others use the sites. The discrepancy of usage may in turn influence social relationship maintenance.

This study is designed to better understand how people complete complicated tasks, and the best ways in which to measure their performance. If you agree to the study, you will be asked to fill out questionnaires on your thoughts, feelings, and behaviors; take a short interview on the same; and complete brain teasers and computerized tests of attention and learning.

There are several steps to determining whether you are a good fit for the study. If you agree to be in the study, then we will send you a link to complete online questionnaires (~10 min) on your thoughts, feelings, and behaviors. If you are a good fit, then we will schedule a laboratory visit in Moore Building at the University Park campus (maximum length of time = 3 hours). During that visit you will complete an interview and more questionnaires, brain teasers, and computerized tests of attention and learning. The visit will be video recorded for quality assurance.

This is a study of the drug DFMO (difluoromethylornithine) for medulloblastoma that has returned or not responded to treatment. DFMO is an oral drug that inhibits a certain enzyme (protein) in blood which is associated with a bad outcome in neuroblastoma cases. Cancer cells have pathways that drive the cancer to grow and DFMO targets the specific pathway of this enzyme to turn these cells off.

You will have exams, tests, and procedures while on the study to evaluate whether you can participate in the study and how you are doing while on the study. These include physical exams, blood tests, urine tests, bone marrow aspirate and biopsies, heart tests, hearing tests, and imaging evaluations such as MRI of your brain and spine. You will receive treatment on this study for a total of about 2 years. After treatment, you will have follow-up examinations and medical tests. We would like to continue to find out about your health for about 5 years after you complete the study.

Postural tachycardia syndrome (POTS) is a chronic syndrome in which the heart beats too quickly when standing. POTS primarily affects young women. People with POTS also experience symptoms such as feeling faint, fatigue, nausea, and mental clouding or "brain fog." “Brain fog” is one of the most bothersome symptoms of POTS and it is unknown why people with POTS experience this symptom. Some studies have shown that POTS patients have problems with attention, memory and executive function (ability to plan, organize information, and adapt to changes) while seated and when upright. In this study, we will evaluate how brain function during mental tasks is affected in people with POTS compared to healthy volunteers. All volunteers will complete mental tasks while lying down and standing. If eligible, we will measure brain activity using functional magnetic resonance imaging (fMRI).The findings from this study will increase our understanding of the mental complaints in people with POTS, to hopefully help with development of new treatments.

There will be three in person visits for this study. At the screening visit, participants will undergo a detailed medical history and physical examination and then will complete a mental test while lying down and standing. If eligible based on the results of the mental test, participants will undergo a pregnancy test if female and of childbearing potential, measurements of blood pressure and heart rate and blood draws while lying down and standing up, and a test to determine if they can tolerate being in a lower body negative pressure (LBNP) device that distributes more blood to the legs to mimic standing. If eligible based on the results of the screening visit, participants will be asked to complete an online questionnaire and two study visits that are separated by at least one week. At these study visits, they will perform a mental test in a magnetic resonance imaging (MRI) scanner. The LBNP device will also be used while in the MRI scanner to distribute more blood to the legs to mimic standing.

Menthol, capsaicin, and camphor are active ingredients often found in over-the-counter pain relief creams and gels. These ingredients typically work by interacting with certain receptors in the skin that are sensitive to temperature changes. There is limited information on how combining menthol with other substances that target similar receptors affects the body. These naturally occurring substances found in plants can widen small blood vessels in the skin through specific processes controlled by nerves in the skin. This study aims to understand how menthol, camphor, and capsaicin individually and together affect sensory function and blood flow in the skin. Additionally, as people age, their skin's nerve and blood vessel function tends to decrease. The study also seeks to explore how aging impacts the effects of these substances on sensory perception and how nerves and blood vessels work together in the skin.

There will be a screening visit and then 6 experiment visits where different topical analgesics will be applied to the forearm skin. We will measure skin blood flow.

The purpose of this study is to test how social decisions are affected by possible risk of infection. We aim to examine the neural and behavioral mechanisms underlying how choices in a risky social decision-making situation can be influenced by viewing images of infection threat (e.g., person with runny nose) vs. images of neutral scenes or other threatening scenes.

Participants will come to the research site for a one-time visit. They will complete brief questionnaires, followed by playing a social decision-making game while undergoing fMRI scanning.

This research study is to provide expanded access to a new investigational drug DFMO (difluoromethylornithine) for patients with neuroblastoma, medulloblastoma, and certain rare tumors that have no other curative options. DFMO is an oral drug that inhibits a certain enzyme (protein) in blood which is associated with a bad outcome in neuroblastoma cases. Cancer cells have pathways that drive the cancer to grow and DFMO targets the specific pathway of this enzyme to turn these cells off.

If you are enrolled on this study, DFMO will be started in clinic on Day 1. After this first day you will be seen in clinic approximately once every 30 days for the first 6 months of study and once every 90 days for the last 18 months of study. These visits will last about 2 hours, and involve a physical exam, blood tests, and other testing.
