Study: Some HIV strains cause early damage to immune system
HealthDay News
Fast-replicating strains of HIV damage the immune system in the very early stages of infection, resulting in quicker disease progression, a new study says. The results confirmed previous findings that people with faster-replicating HIV strains have a quicker decline in levels of infection-fighting immune system CD4 T-cells, the researchers reported in the Proceedings of the National Academy of Sciences.More

New trend in use of real-time management dashboards gives clinical laboratories ability to achieve improved quality and faster test TAT
DARK Daily
Clinical laboratories and anatomic pathology groups are information-rich environments. Yet, there is irony in the fact that — in response to financial pressures and incentives to improve the quality of medical laboratory testing services — most of the nation's clinical labs cannot tap that rich vein of information to support performance improvement goals.

Chickenpox virus may be linked to serious condition in the elderly
American Academy of Neurology via Infection Control Today
A new study links the virus that causes chickenpox and shingles to a condition that inflames blood vessels on the temples and scalp in the elderly called giant cell arteritis. The study is published in the Feb. 18 online issue of Neurology, the medical journal of the American Academy of Neurology. The condition can cause sudden blindness or stroke and can be life-threatening.More

US cancer survival rates improving
The proportion of people surviving years after a cancer diagnosis is improving, according to a new analysis. Men and women ages 50 to 64, who were diagnosed in 2005 to 2009 with a variety of cancer types, were 39 to 68 percent more likely to be alive five years later, compared to people of the same age diagnosed in 1990 to 1994, researchers found.More

Stem cell breakthrough revolutionizes surgery
Newsmax Health
VideoBriefMillions of Americans suffer from crippling wounds that won't heal — including burn victims, cancer patients and military veterans injured in Iraq and Afghanistan. But one southern Florida doctor is out to change that reality with a revolutionary new stem cell procedure that is revolutionizing modern-day surgery. More

Breast cancer spread may be tied to cells that regulate blood flow
University of Texas MD Anderson Cancer Center via Medical Xpress
Tumors require blood to emerge and spread. That is why scientists at the University of Texas MD Anderson Cancer Center believe that targeting blood vessel cells known as pericytes may offer a potential new therapeutic approach when combined with vascular growth factors responsible for cell death.More

New ALS gene, signaling pathways identified
Columbia University Medical Center via ScienceDaily
Using advanced DNA sequencing methods, researchers have identified a new gene that is associated with sporadic amyotrophic lateral sclerosis, or Lou Gehrig's disease. ALS is a devastating neurodegenerative disorder that results in the loss of all voluntary movement and is fatal in the majority of cases. More

DNA damage causes immune reaction and inflammation and is linked to cancer development
Health Canal
For the first time, scientists from Umeå University show the importance of DNA damage in the fine tuning of our innate immune system, and hence the ability to mount the optimal inflammatory response to infections and other biological dangers. The study was published Feb. 17 in the very prestigious international journal Immunity.More

Study identifies potential new drug target for MS
Medical News Today
More than 2.3 million people worldwide are living with multiple sclerosis, a debilitating condition triggered by damage to nerve cells in the central nervous system. But in a new study published in the Annals of Clinical and Translational Neurology, researchers say they may have found a way to reduce this nerve cell damage, paving the way for new treatments for the disease.More

New insight on how brain performs 'mental time travel'
Lab Manager
It is an extreme example of what neuroscientists term "mental time travel" — the recollection of memories so rich in detail regarding the time and place of an original experience that it is much like traveling through time. In a paper published Feb. 18 in the Journal of Neuroscience, a team of Vanderbilt University scientists shed new light on how the brain processes these elaborate memories by analyzing the brain activity of individuals performing a simple memory recollection task.
