We believe that using a ceramide based foot cream two times a day for two weeks will prevent water loss and overall foot dryness in patients with non-insulin dependent diabetes.

BACKGROUND: Lymphomas are comprised of a diversity of tumors with different pathologic and clinical features. While distinct differences in gene expression profiles have been elucidated in different lymphomas, there has been inconsistent correlation with the few published proteo…

This study will investigate HIV infection and associated conditions by monitoring infected patients. The study will also serve as a means for recruiting HIV-infected individuals to NIAIDs ongoing clinical and laboratory studies and supporting the institute s infectious disease tr…

Arterial occlusion can lead to tissue ischemia and, if prolonged, end organ infarction. Clinical and experimental data would suggest that restoration of blood flow might trigger additional injury beyond that induced by the ischemia alone, so called Ischemia Reperfusion (IR) injur…

The aim of the study is to establish the existence of a relationship between the dietary intake of polyunsaturated fatty acids (PUFA) and the risk of colorectal cancer in humans, using 2 reliable and complementary biomarkers: the fatty acid-composition of lipids of the abdominal …
