A more rapid laboratory test for pregnant women to detect potentially deadly Group B strep (GBS) has been successful at identifying GBS colonization in six and a half hours, according to new results.

Why a hereditary anemia is caused by genetic mutation in mechanically sensitive ion channel

Posted: 08 Mar 2013 03:38 PM PST

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a new article.

Recommendations for use of electronic health records in pediatrics

Posted: 08 Mar 2013 03:38 PM PST

In order to speed the development and adoption of electronic health records for pediatrics, a group of experts from industry, academia and government has focused its attention on three key audiences -- records-system vendors and developers, small-group pediatric medical practices and children's hospitals.

Biological tooth replacement is a step closer

Posted: 08 Mar 2013 03:38 PM PST

Scientists have developed a new method of replacing missing teeth with a bioengineered material generated from a person's own gum cells. Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and, as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant.

Appetite suppression pills: Good or bad?

There are endless opportunities to spend a small fortune on a box of pills promising to ease hunger and help lose weight – but they may not be as safe as natural ways to reduce hunger.

Scientists identify buphenyl as a possible drug for Alzheimer's disease

Posted: 08 Mar 2013 03:37 PM PST

Studies in mice with Alzheimer's disease (AD) have shown that sodium phenylbutyrate, known as Buphenyl, successfully increases factors for neuronal growth and protects learning and memory, according to neurological researchers.

Protein lost in tumors blocks normal cells from being reprogrammed into stem cells

Posted: 07 Mar 2013 09:48 AM PST

Researchers have discovered that a particular protein prevents normal cells from being reprogrammed into cells that resemble stem cells, providing new insight into how they may lose their plasticity during normal development.

Vets' PTSD affects mental and physical health of partners

Posted: 07 Mar 2013 09:46 AM PST

A new study of veterans with PTSD and their partners looks at intimate relationship conflict and finds greater physiological and anger responses for the male veterans as well as their female partners. Researchers conclude that the findings may have important implications for treatment and services for returning veterans and their families.

Comparing combination therapies for advanced head and neck cancer shows no improvement

A team of scientists reports results of a clinical trial comparing combination treatments for head and neck cancer.

Novel marker helps identify preeclampsia risk in pregnancy

Posted: 07 Mar 2013 09:44 AM PST

Pregnant women who have a reduced number of capillaries under their skin during pregnancy may be at heightened risk for preeclampsia, according to new research. Researchers say monitoring such changes in small blood vessels early in pregnancy may allow for medical intervention long before the potentially life-threatening condition occurs.

Heart attack rates rise with plunging GDP in Greece's financial crisis

Posted: 07 Mar 2013 09:44 AM PST

Heart attack rates have spiked in Greece since the start of the country's financial crisis, especially among women and residents older than 45, according to a new study.

Cancer-promoting protein is found to also suppress cell growth

Posted: 07 Mar 2013 09:42 AM PST

The cancer-causing oncogene SRSF1, first discovered through its role in splicing, is now shown also to activate cell-growth arrest, or senescence. In states of ribosomal stress or overexpression of SRSF1 it binds to the ribosomal protein RPL5 and prevents degradation of p53. This leads to the phenomenon of oncogene-induced senescence, a program that prevents transformation of normal cells into proliferating cancer cells.

Cholesterol levels rise, fall with changing seasons

Posted: 07 Mar 2013 09:42 AM PST

Cholesterol levels seem to fluctuate significantly with the turning seasons, which may leave some people with borderline high cholesterol at greater cardiovascular risk during the winter months, according to new research.

Age matters in weight gain: Overweight at young age takes toll

Being overweight, especially from a young age, appears to lead to a bigger heart later in life, a condition that has been linked to serious heart problems and even death, according to new research.

Secondhand smoke exposure linked to signs of heart disease: Exposure to tobacco smoke may be more dangerous than previously thought

Posted: 07 Mar 2013 09:39 AM PST

Nonsmokers, beware. It seems the more you are exposed to secondhand tobacco smoke -- whether it was during your childhood or as an adult, at work or at home -- the more likely you are to develop early signs of heart disease.

Dual systems key to keeping chromosomes intact

Posted: 07 Mar 2013 09:39 AM PST

Scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable -- while it is being unzipped for replication.

Persistence pays off in solving hemophilia mystery, showing curiosity drives discovery

Posted: 07 Mar 2013 09:39 AM PST

A medical researcher has found the third and final piece in the genetic puzzle of hemophilia B Leyden, more than 20 years after he discovered the first two pieces. The results explain how more than half of the cases of this rare blood-clotting disorder occur, could have implications for other conditions such as thrombosis and show the value of curiosity-driven research.
