Researchers discover new way to attack some forms of leukemia

Each year, some 29,000 adults and 2,000 children are diagnosed with leukemia, a form of cancer that is caused by the abnormal production of white blood cells in the bone marrow. Current treatments rely primarily on killing the cancer cells, which also destroys normal cells. But what if a way could be found to reprogram cancerous cells back into normal cells? A team of Syracuse University researchers believes it may have found a way to do just that.

New strategy to treat human infections caused by the yeast Candida albicans

Researchers at Georgetown University Medical Center (GUMC) have successfully tested a genetic strategy designed to improve treatment of human infections caused by the yeast Candida albicans, ranging from diaper rash, vaginitis, oral infections (or thrush which is common in HIV/AIDS patients), as well as invasive, blood-borne and life-threatening diseases.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Discovery of earliest known cases of human tuberculosis in Neolithic village

The discovery of the earliest known cases of human tuberculosis (TB) in bones found submerged off the coast of Israel shows that the disease is 3000 years older than previously thought. Direct examination of this ancient DNA confirms the latest theory that bovine TB evolved later than human TB.

Children with cystic fibrosis not well covered by guidelines for vitamin D needs

Existing recommendations for treating vitamin D deficiency in children with cystic fibrosis (CF) are too low to cover the serious need, leaving most at high risk for bone loss and rickets, according to researchers at Johns Hopkins Children's Center.
