There are two main aims of this study. The first aim is to describe rates of jaw pain symptoms in patients who have root canal treatment. The second aim is to test whether a short questionnaire can identify patients with jaw pain.

. I introduce the phenomenon of reverse migration of social entrepreneurs that presumably contributes to the diffusion of this form of entrepreneurship. In this study, using the theoretical frameworks causation and effectuation, I aim to explain the establishment of social enterprises in developing economies founded by non-native entrepreneurs.

The purpose of this study is to establish that a Xenon MRI can detect brown fat and brown fat activity in greater detail in humans than a FDG-PET.

We are surveying individuals with sickle cell disease (SCD) and/or parents of a child with SCD to get a sense of the types of treatment they would choose based on the harms and benefits of those treatment options. The proposed study will be designed to meet the following objectives: 1) Elicit individual respondent's maximum acceptable risk (MAR) for treatment benefits 2) Elicit individual respondent's minimum 3) Characterize heterogeneity in MARs and MABs among respondents

To evaluate the HomeLink program, which is a service designed to provide housing, case management and occupational therapy to individuals living with serious and persistent mental illnesses.

The purpose of this study is to learn how having specific help over a period of time (financial navigation) can help reduce your distress related to the cost of cancer. You will complete a survey to see if you have financial distress. If you have financial distress, you will then fill out a few more surveys and be asked more details about your current financial situation to determine what programs could be helpful for you. The surveys can be completed in person, by email, or over the phone. The navigator can help you complete the surveys if needed. After that, depending on your needs, you will have 1-6 appointments with the financial navigator over a period of 2 weeks -4 months. Risks to you are small due to the educational nature of this study. They may include mild emotional distress while talking about your cancer and financial experiences. Benefits

The purpose of this study is to determine which new magnetic resonance sequences provide better, faster and more useful information. A sequence is a distinct method of obtaining magnetic resonance (MR) images. A magnetic resonance imaging (MRI) exam is made up of many different imaging sequences. These new sequences will be implemented on either on a 3 Tesla (3T) MR system, a 7 Tesla (7T) MR system (single- or multi- transmit), or both. Since the signal-to-noise ratio for MR images is highly dependent on the magnetic field strength, the anticipated signal-to-noise will be 7T greater than 3T and 3T greater than 1.5T systems. The 3T MR system is FDA approved whereas the 7T system is not FDA approved, but is built to the same standards as other FDA approved scanners. In addition, the FDA has approved magnetic field strength up to 8T for human imaging. Participants will be told ahead

Primary: To demonstrate the safety of autologous LSCs administered by intravenous infusion in patients with idiopathic pulmonary fibrosis. Secondary: To demonstrate the efficacy of autologous LSCs administered by intravenous infusion in patients with idiopathic pulmonary fibrosis.
