Study links cardiac hormone-related inflammatory pathway with tumor growth Posted: 28 Jun 2013 10:10 AM PDT A cardiac hormone signaling receptor abundantly expressed both in inflamed tissues and cancers appears to recruit stem cells that form the blood vessels needed to feed tumor growth, a new study finds.

Cancer risks double when two carcinogens present at 'safe' levels, epigenetics study finds Posted: 28 Jun 2013 10:07 AM PDT New research has found that low doses of arsenic and estrogen -- even at levels low enough to be considered "safe" for humans if they were on their own -- can cause cancer in prostate cells.

Scientists view 'protein origami' to help understand, prevent certain diseases Posted: 28 Jun 2013 09:07 AM PDT Scientists using sophisticated imaging techniques have observed a molecular protein folding process that may help medical researchers understand and treat diseases such as Alzheimer's, Lou Gehrig's and cancer. The study verifies a process that scientists knew existed but with a mechanism they had never been able to observe, according to researchers.

Dendritic cell therapy improves kidney transplant survival, team finds Posted: 28 Jun 2013 08:32 AM PDT A single systemic dose of special immune cells prevented rejection for almost four months in a preclinical animal model of kidney transplantation, according to experts. Their findings could lay the foundation for eventual human trials of the technique.

Specialized treatment helps cholesterol patients who suffer side effects from statins Posted: 28 Jun 2013 08:31 AM PDT Up to 15 percent of patients on cholesterol-lowering statin medications experience muscle pain or other side effects, and many stop taking the drugs. But a study has found that a specialized lipid clinic helps "statin-intolerant" patients control their cholesterol.

Better antibiotics: Atomic-scale structure of ribosome with molecule that controls its motion Posted: 28 Jun 2013 07:31 AM PDT Scientists have created an atomic-scale structure of a bacterial ribosome attached to a molecule that controls its motion. The image is also a possible roadmap to better antibiotics. Somewhere in its twists and turns could be a weakness that a new antibiotic can target.

Acid reflux surgery could help prevent rejection in lung transplant patients Posted: 28 Jun 2013 07:31 AM PDT A procedure to treat acid reflux could help prevent chronic rejection in lung transplant patients, according to a new study.

The 'gold' standard: A rapid, cheap method of detecting dengue virus Posted: 28 Jun 2013 06:21 AM PDT Researchers are reporting the development of an easy to use, low cost method of detecting dengue virus in mosquitoes based on gold nanoparticles. The assay is able to detect lower levels of the virus than current tests, and is easy to transport and use in remote regions.

Higher genetic risk tied to lifetime asthma suffering Posted: 28 Jun 2013 06:21 AM PDT Children with more genetic risks for asthma are not only more likely to develop the condition at a young age, but they are also more likely to continue to suffer with asthma into adulthood. The finding is one of the latest to come from a 40-year longitudinal study of New Zealanders.

Time is of the essence for reducing the long-term effects of iron deficiency Posted: 28 Jun 2013 06:21 AM PDT Iron deficiency is a worldwide problem, especially in developing countries and among infants and pregnant women. In infancy, iron deficiency is associated with poorer cognitive, motor, and social-emotional outcomes. In a new study, researchers report on a 25-year follow-up of infants studied in Costa Rica for iron deficiency.

Scientists discover new mechanism regulating the immune response Posted: 28 Jun 2013 06:21 AM PDT Scientists in Finland have discovered a new mechanism regulating the immune response that can leave a person susceptible to autoimmune diseases.

Scientists turn muscular dystrophy defect on and off in cells Posted: 28 Jun 2013 06:17 AM PDT For the first time, scientists have identified small molecules that allow for complete control over a genetic defect responsible for the most common adult onset form of muscular dystrophy.

Lithium reduces risk of suicide in people with mood disorders, review finds Posted: 27 Jun 2013 04:06 PM PDT The drug lithium is an effective treatment for reducing the risk of suicide and possibly deliberate self harm in people with mood disorders, an evidence review finds.

Fatty acids found in fish linked to lower risk of breast cancer Posted: 27 Jun 2013 04:06 PM PDT A high intake of fatty acids found in fish is associated with a 14 percent reduction in the risk of breast cancer in later life, a new study finds.

New red blood cell simulator invented Posted: 27 Jun 2013 09:52 AM PDT Engineers have developed the world's most precise computer simulation of how red blood cells might travel around the body to help doctors treat people with serious circulatory problems.

Insights into how brain compensates for recurring hearing loss point to new glue ear therapies Posted: 27 Jun 2013 09:52 AM PDT Important new insights into how the brain compensates for temporary hearing loss during infancy, such as that commonly experienced by children with glue ear, are revealed in a research study in ferrets. The study could point to new therapies for glue ear and has implications for the design of hearing aid devices.
