We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well as glucose (sugar), certain fats, and other molecules related…
Depression and some antidepressants may be associated with an increased risk of breaking a bone. It is not clear why this could be the case. It is possible that depression and/or certain medications used for the treatment of depression cause bone loss, increase the risk of falls, are associated with lower physical activity, or effects on muscle function.…

The goal of this study is to determine if treating acute wheezing episodes with a 5-day course of an antibiotic called, Azithromycin is effective in shortening the duration and preventing future wheezing episodes. Azithromycin is an antibiotic taken by mouth.
We are studying the causes of and potential treatments for pregnancy & lactation-associated osteoporosis (PLO). We know little about the clinical features, causes, and prognosis of PLO. Our goal is to define the clinical characteristics of PLO and better understand similarities/differences among the women. We are looking for women with fractures during/…
Pain is a natural response to injury to let us know there may be damage to our bodies. Pain is the way our body tells us that we must take care of ourselves. Chronic pain is different and lasts for a long time. In some cases, chronic pain remains without any sign of body damage. Today, there is no way for a doctor to measure someone's chronic pain or…
Precision medicine is an individual-based care, a new approach to care based on someone's medical history, where they live, and profile (age, gender, and so on). We will use precision medicine to understand treatments for severe asthma. These treatments are not yet used for asthma today. We have two goals for the PrecISE study: 1. Make it easier to…
We're conducting a research study on how much insulin is needed to control blood sugar in people who are made temporarily resistant to insulin's effects. Insulin is the main hormone (chemical signal) that the body uses to lower the levels of sugar in the blood. We are interested in looking at insulin levels because we think that lowering insulin…
The goal of this study is to learn whether treatment with a safe, commonly used drug called ATENOLOL prevents bone loss in women after menopause. Who Qualifies? Healthy post-menopausal women who are between the ages of 50 and 75. You may not be eligible if you have certain medical conditions. What's Involved? If you are eligible, you will be assigned…
The shoulder joint is the most mobile joint in the human body, steered by a group of muscles and their respective tendons, together called the rotator cuff. A consequence of this mobility is a vulnerability to degradation, or wear and tear, of tendons and inflammation in the surrounding area. Our study aims to create biological samples and data bank to get…
