Cancer cells have multiple ways to avoid apoptosis, programmed cell death the means by which organisms deal with defective cells. One defense is to produce quantities of phosphatic acid, a phospholipid constituent of cellular membranes.

Patients with acute liver failure (ALF) could be saved by a transplant from a living donor (LDLT), according to a new study in the September issue of Liver Transplantation, a journal by John Wiley & Sons. The recent experience of U.S. patients shows that recipient mortality rates and donor morbidity rates are acceptable.
