Deer proliferation disrupts a forest's natural growth Posted: 08 Mar 2014 06:55 AM PST Researchers have discovered that a burgeoning deer population forever alters the progression of a forest's natural future by creating environmental havoc in the soil and disrupting the soil's natural seed banks.

Opioid regimens that deliver best pain control reflect assay findings of cytochrome defects Posted: 08 Mar 2014 06:48 AM PST Most patients with multiple defects of the cytochrome P450 system, which is largely responsible for metabolizing opioids, naturally gravitated toward an opioid regimen primarily metabolized through the cytochrome P450 3A4 enzyme or a non-cytochrome, metabolic pathway, a new study suggests.

Combined use of oxytocin and human chorionic gonadotropin in intractable pain patients Posted: 08 Mar 2014 06:48 AM PST Two hormones credited with reducing pain and need for opioid analgesics when released naturally during pregnancy and childbirth worked similarly when administered simultaneously to patients with intractable pain, research shows.

Stem cell transplant shows 'landmark' promise for treatment of degenerative disc disease Posted: 08 Mar 2014 06:48 AM PST Stem cell transplant was viable and effective in halting or reversing degenerative disc disease of the spine, a meta-analysis of animal studies showed, in a development expected to open up research in humans. Recent developments in stem cell research have made it possible to assess its effect on intervertebral disc (IVD) height, researchers reported.

New NASA Van Allen Probes observations helping to improve space weather models Posted: 07 Mar 2014 01:59 PM PST Using data from NASA's Van Allen Probes, researchers have tested and improved a model to help forecast what's happening in the radiation environment of near-Earth space -- a place seething with fast-moving particles and a space weather system that varies in response to incoming energy and particles from the sun.

Ever-so-slight delay improves decision-making accuracy Posted: 07 Mar 2014 01:59 PM PST Researchers have found that decision-making accuracy can be improved by postponing the onset of a decision by a mere fraction of a second. The results could further our understanding of neuropsychiatric conditions characterized by abnormalities in cognitive function and lead to new training strategies to improve decision-making in high-stake environments.

The dark side of fair play Posted: 07 Mar 2014 01:59 PM PST We often think of playing fair as an altru­istic behavior. We're sac­ri­ficing our own poten­tial gain to give others what they deserve. What could be more self­less than that? But new research sug­gests another, darker origin behind the kindly act of fairness. An expert in the evolution of spite has investigated possible explanations for fair behavior that hadn't been considered before.

Personalized treatment prolongs the life of lung cancer patients Posted: 07 Mar 2014 01:59 PM PST Mexican scientists have increased survival rates for patients diagnosed with lunch cancer in metastatic stage (when the disease has spread to different parts of the body) from a rate of nine months of survival to 30 with personalized treatments. Tumor tissue samples were used to extract DNA in order to analyze mutations in the neoplasia (abnormal mass of tissue). Based on the mutations, personalized treatments were provided to the study participants.

Over demanding market affects fisheries more than climate change Posted: 07 Mar 2014 01:59 PM PST Fisheries that rely on short life species, such as shrimp or sardine, have been more affected by climate change, because this phenomenon affects chlorophyll production, which is vital for phytoplankton, the main food for both species.

Blue paint on Japanese bullet trains can inhibit bacterial growth Posted: 07 Mar 2014 01:58 PM PST Using an artificial protein that contains metal, researchers were able to inhibit the growth of a pathogenic bacterium prevalent in hospitals which cause diseases to humans and has a high resistance to antibiotics.

Anti-Psychotic Meds Offer Hope Against Brain Cancer Posted: 07 Mar 2014 11:30 AM PST FDA-approved anti-psychotic drugs possess tumor-killing activity against the most aggressive form of primary brain cancer, glioblastoma, new research indicates. "The anti-glioblastoma effects of these drugs are completely unexpected and were only uncovered because we carried out an unbiased genetic screen," said the lead author.

Primary care needs to 'wake-up' to links between domestic abuse, safeguarding children Posted: 06 Mar 2014 04:15 PM PST Researchers looking at how healthcare professionals deal with domestic violence cases have identified that GPs, practice nurses and practice managers are uncertain about how to respond to the exposure of children to domestic violence. In this study, researchers found that primary care practitioners had little knowledge of local domestic violence services and few had direct communication with children's social services. The study also found practitioners' face-to-face communication with children and young people was limited.
