New formula accurately measures kidney function in children

Measuring a child's kidney function has traditionally been time-consuming, costly, and difficult to perform, but a new equation that uses parameters collected at routine office visits can effectively accomplish this, according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology ( JASN ).

Potential new target in the war on HIV/AIDS

The study revealed that a variant of a protein involved in HIV pathogenesis can suppress production of an HIV protein, known as Nef. Nef is required for the human immunodeficiency virus to develop into AIDS through a series of complex events involving viral elements and cellular proteins. Nef has never been a target for drug treatment in HIV patients.
