Now scientists have shown that interferon-gamma plays a deciding role in whether immune cells attack and injure the central nervous system (brain and spinal cord) in mice. ... > full story
Cell Changes Leading To Impaired 'Artificial Kidney' Function Identified (November 1, 2008) -- Molecular targets identified by a Spanish research team may hold the key to freedom for some sufferers of kidney disease. A new study reveals the cellular signals which cause one treatment for kidney failure to lose its usefulness over time. ... > full story
'Old Blood' Linked To Infection (November 1, 2008) -- Patients who received transfusions with blood stored for 29 days or more were twice as likely to suffer from nosocomial infections, including pneumonia, upper respiratory infections and sepsis, with the oldest blood being associated with the most infections.

Once Improbable James Bond Villains Now Close To Real Thing, Spy Researcher Says (October 31, 2008) -- Researchers say that the once improbable seeming villains in the Bond movies have become close to the real threats face faced by modern security services. One researcher said, "Remarkably, the Bond villains - including Dr No, Goldfinger and Blofeld - have always been post-Cold War figures.

Gaining Too Much Weight During Pregnancy Nearly Doubles Risk Of Having A Heavy Baby (October 31, 2008) -- A study of over 40,000 women and their babies found that women who gained more than 40 pounds during their pregnancies were nearly twice as likely to have a heavy baby. The study found that more than one in five women gains excessive weight during pregnancy, doubling her chances of having a baby that weighs 9 pounds or more. ... > full story
By Imaging Live Cells, Researchers Show How Hepatitis C Replicates (October 31, 2008) -- The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery. Now new research -- in which scientists have for the first time used fluorescent proteins to image hepatitis C virus replication in live cells -- shows that the microscopic viral factories are a diverse mix of big, immobile structures and tiny replication complexes that zip zanily around inside the cell. ... > full story
