Gene mutation discovery sparks hope for effective endometriosis screening Posted: 06 Feb 2012 02:43 PM PST Researchers have, for the first time, described the genetic basis of endometriosis, a condition affecting millions of women that is marked by chronic pelvic pain and infertility. The researchers' discovery of a new gene mutation provides hope for new screening methods.

Metabolic 'breathalyzer' reveals early signs of disease Posted: 06 Feb 2012 02:42 PM PST The future of disease diagnosis may lie in a "breathalyzer"-like technology currently under development.

Big jolt to California economy with new tax on cigarettes Posted: 06 Feb 2012 02:42 PM PST A new analysis has found that a state ballot initiative to increase the cigarette tax would create about 12,000 jobs and nearly $2 billion in new economic activity in California.

Three 'targeted' cancer drugs raise risk of fatal side effects Posted: 06 Feb 2012 02:42 PM PST Treatment with three "targeted" cancer drugs has been linked to a slightly elevated chance of fatal side effects, according to a new analysis. These risks remain low, but they should be factored in when developing patients' treatment plans.

School Closures Slow Spread of pH1N1 Posted: 06 Feb 2012 02:42 PM PST Using high-quality data about the incidence of influenza infections in Alberta during the 2009 H1N1 flu pandemic, the researchers show that when schools closed for the summer, the transmission of infection from person to person was sharply reduced.

Clues to common birth defect found in gene expression data Posted: 06 Feb 2012 12:41 PM PST Researchers have uncovered 27 new candidate genes for congenital diaphragmatic hernia, a common and often deadly birth defect. Their sophisticated data-filtering strategy offers a new, efficient and potentially game-changing approach to gene discovery.

Medical debt keeps rising, new report shows Posted: 06 Feb 2012 11:41 AM PST A comprehensive new report on health insurance shows the so-called Great Recession caused hundreds of thousands of Californians to lose coverage and acquire medical debt.

Discovery predicts patient sensitivity to important drug target in deadly brain cancer Posted: 06 Feb 2012 11:41 AM PST A recent discovery enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma – the most common and most aggressive malignant brain tumor in humans.

PET techniques provide more accurate diagnosis, prognosis in challenging breast cancer cases Posted: 06 Feb 2012 11:39 AM PST Researchers are revealing how molecular imaging can be used to solve mysteries about difficult cases of breast cancer. One recent article focuses on an imaging agent that targets estrogen receptors in estrogen receptor–positive breast cancer patients with formerly inconclusive assessments, and the second highlights a different imaging agent's ability to help predict the prognosis for patients undergoing chemotherapy for a very aggressive type of breast cancer.

Exercise triggers stem cells in muscle Posted: 06 Feb 2012 11:39 AM PST Researchers have determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age.

Raw milk is a dangerous raw deal for farmers and consumers, experts say Posted: 06 Feb 2012 11:38 AM PST Researchers and experts on food safety have commented on the danger presented to farmers and consumers by the raw milk movement.

Key finding in stem cell self-renewal Posted: 06 Feb 2012 09:27 AM PST Scientists have proposed a mechanism for the control of whether embryonic stem cells continue to proliferate and stay stem cells, or differentiate into adult cells like brain, liver or skin. The work has implications in two areas. In cancer treatment, it is desirable to inhibit cell proliferation.

Low levels of lipid antibodies increase complications following heart attack Posted: 06 Feb 2012 07:29 AM PST Coronary patients with low levels of an immune system antibody called anti-PC, which neutralizes parts of the "bad" cholesterol, run a greater risk of suffering complications following an acute cardiac episode and thus of premature death.

Combined approach to global health has benefits Posted: 06 Feb 2012 06:26 AM PST A new analysis demonstrates that confronting several diseases at once is a viable way to make the most of thinly stretched donor dollars and national health care budgets, and help save more lives.

Strategy shift with age can lead to navigational difficulties Posted: 06 Feb 2012 06:26 AM PST A researcher believes studying people's ability to find their way around may help explain why loss of mental capacity occurs with age.

Children hospitalized at alarming rate due to abuse, U.S. study finds Posted: 06 Feb 2012 06:26 AM PST In one year alone, over 4,500 children in the United States were hospitalized due to child abuse, and 300 of them died of their injuries, researchers report in a new study.

Positive parenting during early childhood may prevent obesity Posted: 06 Feb 2012 06:25 AM PST Programs that support parents during their child's early years hold promise for obesity prevention, according to a new study.

Did your surgeons miss something? New system to prevent retained surgical items Posted: 06 Feb 2012 06:25 AM PST It may sound like something from a TV medical drama, but the incidence of surgeons leaving something behind in the body is very real at hospitals across the country. But researchers have now created a new system using state-of-the-art technologies to insure that no foreign objects are left behind during surgery.
