Scientists develop tool to study a deadly parasite’s histone code

In the Japanese art of paper folding, a series of folds can make the same sheet of paper into a ballerina or baby elephant. But try unfolding the baby elephant and making it into a ballerina. It's like trying to make a neuron from a kidney cell. Epigenetics, it turns out, isn't much different from this old Japanese art: Each fold, or epigenetic crease, both limits and permits further potential folds in a way that mirrors how epigenetic changes seal a cell's fate.

Traumatic brain injury haunts children for years

Traumatic Brain Injury (TBI) is the single most common cause of death and disability in children and adolescents, according to the Centers for Disease Control. Now, according to a new study by UCLA researchers, the effects of a blow to the head, whether it's mild or a concussion, can linger for years.

Anti-viral ribavirin may prove effective in treatment of many cancers

A ground-breaking Canada-wide clinical trial led by Dr. Katherine Borden, at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal, has shown that a common anti-viral drug, ribavirin, can be beneficial in the treatment of cancer patients.

New insights into immune exhaustion

A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out.

Diuretic drug works best at reducing risk of heart failure in hypertension

New research supports the findings of a landmark drug comparison study published in 2002 in which a diuretic drug or "water pill" outperformed other medications for high blood pressure. A scientific team including investigators from The University of Texas Health Science Center at Houston reports the findings in the May 11 issue of the Archives of Internal Medicine.

New mathematical model predicts immune response to influenza A virus

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). This model examines the contributions of specific sets of immune cells in fighting influenza A virus.
