Epigenetics: A key to controlling acute and chronic pain Posted: 25 Oct 2013 10:52 AM PDT Epigenetics, the study of changes in gene expression through mechanisms outside of the DNA structure, has been found to control a key pain receptor related to surgical incision pain, according to a new study. This study reveals new information about pain regulation in the spinal cord.

Understanding DNA damage from common radiation threat, low-energy electrons Posted: 25 Oct 2013 09:30 AM PDT Every day, all day, our DNA gets beaten up by chemicals and radiation -- but remarkably, most of us stay healthy. Now, an investigation has produced insights into a little-studied but common radiation threat to DNA: low-energy electrons (LEEs), with energies of 0-15 electron volts.

Nano-dwarves turn tumor assassins Posted: 25 Oct 2013 07:22 AM PDT Chemotherapy is often preferred for fighting cancer, but its side effects can be considerable. A new technique may reduce these in future: nanoparticle-encapsulated substances could kill off tumor cells selectively. This will be easier on patients.

Children with brain injuries nearly twice as likely to suffer from depression Posted: 25 Oct 2013 06:19 AM PDT Researchers have found that compared to other children, 15 percent of those with brain injuries or concussions were diagnosed as depressed -- a 4.9 fold increase in the odds of diagnosed depression.

Important step towards stem cell-based treatment for stroke Posted: 25 Oct 2013 06:17 AM PDT Brain infarction, or stroke, is caused by a blood clot blocking a blood vessel in the brain, which leads to interruption of blood flow and shortage of oxygen. Now a reserach group has taken an important step towards a treatment for stroke using stem cells.

Lou Gehrig’s disease: From patient stem cells to potential treatment strategy Posted: 25 Oct 2013 06:14 AM PDT A study is believed to be one of the first in which a specific form of Lou Gehrig's disease, or amyotrophic lateral sclerosis, was replicated in a dish, analyzed and "treated," suggesting a potential future therapy all in a single study.

'High-risk' organs from deceased donors safe when screened with current methods Posted: 25 Oct 2013 06:14 AM PDT A study has shown that after a median of 2.4 years of follow up, 86.5% of transplants of donor kidneys considered "high-risk" for infection and disease were functioning with no evidence of infections. Such "high-risk" organs are relatively safe when screened with current methods.

Kids' asthma medication frequently administered inaccurately, leading to poor health outcomes Posted: 24 Oct 2013 03:24 PM PDT Caregivers' often administer their child's asthma medication inaccurately, which leads to poor health outcomes for those children.

Insights into genetic architecture of OCD, tourette syndrome Posted: 24 Oct 2013 03:24 PM PDT An international research consortium has answered several questions about the genetic background of obsessive-compulsive disorder (OCD) and Tourette syndrome (TS), providing the first direct confirmation that both are highly heritable and also revealing major differences between the underlying genetic makeup of the disorders.

Study finds that paying people to become kidney donors could be cost-effective Posted: 24 Oct 2013 03:24 PM PDT Paying living donors $10,000 could be cost-saving even if it only resulted in a 5% increase in the number of donors.
