Major Advance In Cancer Radiotherapy (November 15, 2008) -- Radical improvements in outcome for many cancer sufferers are in prospect following one of the most significant advances in radiotherapy since x-rays were first used to treat a tumor in 1904. The use of charged particles as an alternative to x-ray or gamma ray radiation can extend the scope of radiotherapy to tumors previously requiring invasive surgery, while speeding up diagnosis and reducing collateral damage to surrounding tissue. ... > full story

Repairing DNA Damage: Researchers Discover Critical Process In Cancer Treatment (November 15, 2008) -- From the sun's UVA rays to tobacco smoke, our environment is chock-full of DNA-damaging agents that can lead to cancer. Thanks to our body's DNA repair mechanisms, however, the effects of many carcinogens can be reversed thereby preventing the formation of tumours. Now, scientists have identified a new biochemical pathway which controls DNA repair. ... > full story

Predictive Tests And Early Treatment Delay Progression Of Blood Cell Cancer, Researchers Find (November 15, 2008) -- Mayo Clinic researchers say they have moved closer to their goal of providing personalized care for a common blood cell cancer. They have found that the use of predictive biomarkers along with two targeted treatments significantly delays the need for conventional chemotherapy in patients with early-stage, but high-risk, chronic lymphoid leukemia. ... > full story

Doctors Must Look After Their Health, Too, Study Recommends (November 15, 2008) -- Short term counseling followed by a modest cut in work hours may help reduce emotional exhaustion and sick leave in doctors, according to a new study. ... > full story

Unraveling Mystery Of Brain Aneurysms (November 15, 2008) -- Researchers have taken the first critical steps in unraveling the mysteries of brain aneurysms, the often fatal rupturing of blood vessels that afflicts 500,000 people worldwide each year and nearly killed Vice President-elect Joseph Biden two decades ago. ... > full story

Caring For The Caregiver: Redefining The Definition Of Patient (November 15, 2008) -- One quarter of all family caregivers of Alzheimer's disease patients succumb to the stress of providing care to a loved one and become hospital patients themselves, according to a new study in the Journal of General Internal Medicine. ... > full story

Protecting Neurons Could Halt Alzheimer's, Parkinson's Diseases (November 15, 2008) -- Researchers have identified a group of chemical compounds that slow the degeneration of neurons, a condition behind old-age diseases like Alzheimer's, Parkinson's and amyotrophic lateral sclerosis (ALS). ... > full story

Herpes Drug Inhibits HIV Replication, But With A Price (November 15, 2008) -- The anti-herpes drug acyclovir can also directly slow down HIV infection by targeting the reverse transcriptase enzyme, researchers report. This beneficial effect does pose a risk though, as HIV-infected cells treated with acyclovir promote the emergence of multi-drug resistant HIV variants. ... > full story

Therapy May Block Expansion Of Breast Cancer Cells (November 15, 2008) -- Breast cancer stem cells are known to be involved in therapy resistance and the recurrence of cancerous tumors. A new study shows the mechanisms governing stem cell expansion in breast cancer (called Notch activity), and finds that therapy targeting a protein called cyclin D1 may block the expansion of cancerous stem cells. ... > full story

With GPS, They Know Where You Are (November 15, 2008) -- How can we keep our personal location private in a society where GPS-enabled devices and internet-connected computing is ubiquitous? That is the question posed by a computing and legal specialist in Belgium. ... > full story

Vitamin C Lowers Levels Of Inflammation Biomarker Considered Predictor Of Heart Disease (November 14, 2008) -- For people who have elevated levels of C-reactive protein, a predictor of heart disease, taking vitamin C supplements can help lower levels of the inflammation biomarker, according to a new study. The new findings come just days after a major, eight-year clinical trial failed to show that vitamins C or E could cut the risk of heart attacks or strokes. ... > full story
