Cells able to switch genetic profile: Implications for cancer drug testing
ScienceDaily    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Scientists at the University of East Anglia have made an important breakthrough in the way anti-cancer drugs are tested. A tumor cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumors taking hold. More



First babies born in IVF full gene screening study
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Two women have given birth to healthy babies from eggs screened for genetic defects before being implanted in the womb, in a study of a new technique that could improve the success rate of in-vitro fertilization. Twin girls born in Germany in June and a boy born in Italy in September are the first deliveries in a pilot study of a technique called comparative genomic hybridisation (CGH) by microarray, European scientists said.

Gene offers possible target for blocking neuron loss
early in Parkinson's disease

Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A gene that regulates the expression of numerous other genes involved in cellular energy supply has been identified as a strong therapeutic target for early Parkinson's disease. The controlling gene, PGC-1α, is underexpressed in Parkinson's patients, whereas its overexpression blocks the loss of dopaminergic neurons in Parkinson's disease models, researchers report. The study, published in the first-anniversary issue of Science Translational Medicine, is the first research published by the Global Parkinson's Disease Gene Expression Consortium, a group of international researchers united in 2003 by their interest in cellular mechanisms of Parkinson's.

Army finds simple blood test to identify mild brain trauma
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Army says it has discovered a simple blood test that can diagnose mild traumatic brain damage or concussion, a hard-to-detect injury that can affect young athletes, infants with "shaken baby syndrome" and combat troops. "This is huge," said Gen. Peter Chiarelli, the Army vice chief of staff. Army Col. Dallas Hack, who has oversight of the research, says recent data show the blood test, which looks for unique proteins that spill into the blood stream from damaged brain cells, accurately diagnosing mild traumatic brain injury in 34 patients.

Cell culture-derived influenza vaccine as effective as traditional one
Reuters Health via Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A flu vaccine made through a speedier production method appears to be as safe and effective as one produced in the traditional way, a study suggests. The conventional flu vaccine is produced using chicken eggs to grow the virus, a slow process that makes it hard to quickly boost production in response to a pandemic, such as the H1N1 flu outbreak of 2009.

Mystery virus still keeping secrets
MedPage Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The mysterious retrovirus recently associated with prostate cancer and chronic fatigue syndrome remains, mysterious. … The virus was first linked with prostate cancer in 2006 after investigators found it in a subset of patients with a genetic variant that impairs innate immune responses to viral infection. Because people with chronic fatigue syndrome have the same variant, researchers also looked for — and found — XMRV in a cohort of such patients. More

WHO: Control of neglected tropical diseases is feasible
Medical News Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The misery and disability caused by a group of chronic infectious diseases, found almost exclusively in very poor populations, can now be substantially reduced, according to a new report released today by WHO. The report, "Working to overcome the global impact of neglected tropical diseases," covers 17 neglected tropical diseases1 that thrive in impoverished settings, where housing is often substandard, environments are contaminated with filth, and disease-spreading insects and animals abound.

Is your touch-screen dirtier than a toilet flusher?
TIME Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Insert "going viral" joke here: a study conducted by Stanford researchers found that letting your friends handle your cool new touch-screen device could mean sharing more than the latest technology. You could also be passing around all manner of viruses and bacteria, including the influenza virus. The study found that the risk of transmitting illness-causing bugs through the glass surfaces of an iPhone, iPad, Droid or other similar device is pretty high. Study co-author, Stanford doctoral student Timothy Julian. More
