Protein S is a protein that is very important to the blood clotting process. When people don't have enough Protein S they run the risk of developing blood clots. This study is collecting samples from people who may have abnormal Protein S levels in order to develop a new way of checking the Protein S levels. This test is looking specifically for FREE Protein S. The free protein S is Protein S that is not bound or "tied up" and is therefore more ready to do its job in the clotting process.
The Acute Respiratory Distress Syndrome (ARDS) is a major cause of mortality and morbidity in critically ill patients. There are no proven effective pharmacologic therapies for the syndrome in part because the current understanding of the causes of ARDS is limited. The aims of this study are to examine the role that extracellular micro RNA play in the endothelial and epithelial dysfunction which occurs in ARDS.
Individuals with venous leg and diabetic foot ulcers often find these ulcers take a long time to heal and when they do, sometimes they come back. These ulcers can be quite painful making it hard to work, sleep and go about one's day to day activities. You will be asked to do a self-care routine of taking the temperature of the skin where the leg or foot ulcer just healed with a special thermometer and applying a small cooling gel patch over this skin. We want to know if this routine will prevent the ulcer from coming back, help you to become more active, and improve the quality of your life.
This study will test a low intensity foot exercise program for people with lower leg ulcers and who have problems with walking to see if it improves the condition of the legs. A small activity monitoring tracker called an accelerometer will be placed on the foot during the exercises that are to be done in the home for about 6 weeks. The tracker sends movement information to a cell phone that lets you and your doctor know about improvements in the foot movements. Better foot movements help condition the muscles and joints and may improve activity such as walking and getting up from a chair.
