Cells in mucus from lungs point to a unique screening method that could lead to earlier treatment of lung cancer

In a group of high-risk patients, a test that examined DNA from cells expelled in sputum for evidence of "silenced" genes correctly identified the majority of patients who were later diagnosed with lung cancer, say researchers in a study published in the March 15 issue of Cancer Research.

Researchers find viable new sources for stem cell transplants to the heart

Stem cell transplantation is among one of the most exciting and hotly debated areas of medical research today. While the promise of personalized medicine and effective treatments for debilitating diseases drive progress in this area, moral and ethical dilemmas about embryonic cells continues to cloud the field.

Low pressure and low oxygen factors in DVT and long flights

Researchers say that the risk of deep vein thrombosis (DVT) during flights may not be due simply to sitting still; they say the low pressure and low oxygen environment during air travel may also contribute to the development of deep vein thrombosis in some susceptible individuals.

Study reveals mechanisms behind Thiazolidinediones used to treat type 2 diabetes

Thiazolidinediones (TZD's) are drugs commonly prescribed to patients with type 2 diabetes, the most common form of diabetes. Current U.S. Food and Drug Administration-approved agents are known as Actos (pioglitazone) and Avandia (rosiglitazone).

Scientists exploit novel route to reverse enlarged hearts in obese mice

Working on genetically engineered obese mice with seriously thickened hearts, a condition call cardiac hypertrophy, scientists at Johns Hopkins have used a nerve protection and growth factor on the heart to mimic the activity of the brain hormone leptin, dramatically reducing the size of the heart muscle.
