Official Title Mechanisms of Negative Affectivity

Purpose

Symptoms related to depression and anxiety can affect a person’s daily life and relationships. Some research suggests that people with mood and anxiety disorders process information differently than people without these types of disorders.

The purpose of this study is to better understand the way the brain works in people who have depression and anxiety. Researchers hope their findings will lead to better ways to diagnose and treat mood and anxiety disorders in the future.

Participation involves an initial phone call and a 3 to 5 hour visit to find out if you are eligible. This visit will include completing questionnaires and interviews. If eligible, participants will have a second 3-5 hour visit for an MRI scan.

The 3rd and 4th visits (at 6 and 12 months) will include 1.5 to 3 hours of questionnaires and interviews each.

Following the scan, the 6-month follow-up, and the 12-month follow-up, participants will also complete daily online questionnaires for 7 days.

Official Title Adipocyte-T Cell Interactions Modulate Adipose Inflammation and Insulin Sensitivity Following Weight Gain

Purpose

The purpose of this research study is to better understand the role of fat tissue, how cells in fat tissue communicate, and determine what signals specific cells use to cause inflammation and insulin resistance during weight gain. This may help researchers better understand the process that happens in Type 2 Diabetes. As a result, through the course of six--nine weeks, participants will be asked to gain at least 10% of their starting body weight. A dietitian will meet with participants to give advice to help with meeting the study weight gain goals, as well as provide additional meal vouchers and supplemental shakes as needed. Following the study, participants will receive guidance how to lose the weight they've gained if they would like to do that.

Official Title Perinatal Arterial Stroke: The I-ACQUIRE Study

Purpose

Children who suffered a stroke before or shortly after being born that was caused by blockage of blood flow in an artery, it often results in the child showing some weakness on one side of their body.

All children will be in the study for about 13 - 15 months. Some children may be in the study for a longer period, depending on which treatment they receive during Phase 1 of the study. The I-ACQUIRE therapy involves fun learning and play, self-help activities, and manipulating interesting toys and objects.
