Living donor liver transplants may drastically decrease mortality from liver failure
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.
New evidence on the robustness of metabolic networks
Biological systems are constantly evolving in ways that increase their fitness for survival amidst environmental fluctuations and internal errors. Now, in a study of cell metabolism, a Northwestern University research team has found new evidence that evolution has produced cell metabolisms that are especially well suited to handle potentially harmful changes like gene deletions and mutations.
Studies spot numerous undiscovered gene alterations in pancreatic and brain cancers
HHMI investigators have detected a multitude of broken, missing, and overactive genes in pancreatic and brain tumors, in the most detailed genetic survey yet of any human tumor. Some of these genetic changes were previously unknown and could provide new leads for improved diagnosis and therapy for these devastating cancers.
