Omega-3 fatty acids may help heal a broken heart

Posted: 30 May 2013 08:11 AM PDT

Procedures like angioplasty, stenting and bypass surgery may save lives, but they also cause excessive inflammation and scarring, which ultimately can lead to permanent disability and even death. A new research report shows that naturally derived compounds from polyunsaturated fatty acids (omega-3s) may reduce the inflammation associated with these procedures to help arteries more fully and completely heal.

New gene delivery method: Magnetic nanoparticles

Posted: 30 May 2013 08:11 AM PDT

Stent angioplasty saves lives, but comes with complications. A new nanoparticle gene delivery method will hopefully overcome limitations of gene therapy vectors and prevent complications associated with stenting. Stents are the platform for magnetically targeted gene delivery, where genes are moved to cells at arterial injury locations without side effects. These nanoparticles protect genes and help them reach their target in active form, a challenge in gene therapy.

New discovery permits rapid diagnosis and treatment of sepsis

Posted: 30 May 2013 08:11 AM PDT

Despite advances in treating infections and disease, effective treatments for sepsis remain elusive. New research could help health care providers predict who may or may not develop sepsis, and facilitate new therapies to address the root causes, rather than just managing the symptoms. This also may benefit patients suffering from viral infections, as well as chronic inflammatory diseases such as rheumatoid arthritis and chronic obstructive pulmonary disease.

Newly discovered hormone makes ovaries grow

Posted: 30 May 2013 08:11 AM PDT

Researchers have identified a new hormone called "R-spondin2" that promotes follicle development and stimulates ovary growth.

MRSA study slashes deadly infections in sickest hospital patients

Posted: 30 May 2013 06:50 AM PDT

Using germ-killing soap and ointment on all intensive-care unit (ICU) patients can reduce bloodstream infections by up to 44 percent and significantly reduce the presence of methicillin-resistant Staphylococcus aureus (MRSA) in ICUs. A new study tested three MRSA prevention strategies and found that using germ-killing soap and ointment on all ICU patients was more effective than other strategies.

Epigenetic biomarkers may predict if a specific diet and exercise regimen will work

Posted: 30 May 2013 06:49 AM PDT

Would you try a diet and exercise regimen knowing in advance it would actually help you lose weight? New research shows that this could become reality. Scientists have identified five epigenetic biomarkers in adolescents associated with better weight loss at the beginning of a weight loss program. This could help predict an individual's response to weight loss intervention, and offer targets for enhancing a weight loss program's effects.

Give barefoot running the boot?

Posted: 30 May 2013 06:48 AM PDT

Barefoot running has been making headlines ever since 1960, when a shoeless Abebe Bikila set a new world-record marathon time at the Rome Olympics. Even manufacturers have muscled in on the trend over the years, with most now offering their own version of 'barefoot' or 'minimalist' shoes.

Immune system to fight brain tumors

Posted: 30 May 2013 06:48 AM PDT

Research gives hope that one of the most serious types of brain tumor, glioblastoma multiforme, could be fought by the patients' own immune system. The tumors are difficult to remove with surgery because the tumor cells grow into the surrounding healthy brain tissue. A patient with the disease therefore does not usually survive much longer than a year after the discovery of the tumor.

Origins of key cells in the thymus

Posted: 30 May 2013 06:46 AM PDT

Medullary thymic epithelial cells (mTECs) allow the thymus to ensure that the body's T cells are able to distinguish between potentially harmful foreign antigens and those that are produced by the body itself. New research suggests that mTECs do not share a common progenitor with cortical-thymic TECs (cTECs) that produce T cells, but may actually evolve from them.

Big feet preference in rural Indonesia defies one-size-fits-all theory of attractiveness

Posted: 30 May 2013 06:44 AM PDT

People in most cultures view women with small feet as attractive and a sign of a potential mate's youth and fertility. But a new research study shows that the Karo Batak living in rural villages in Indonesia deem women with big feet as more appealing, suggesting that culture – not just genetics – plays a role in deciding what makes a mate attractive.
