More rapid test for Group B strep successful Posted: 08 Mar 2013 03:38 PM PST 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.

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.

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 Posted: 07 Mar 2013 09:45 AM PST 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 Posted: 07 Mar 2013 09:42 AM PST 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.

Fatty acids could lead to flu drug Posted: 07 Mar 2013 09:39 AM PST Flu viruses are a major cause of death and sickness around the world, and antiviral drugs currently do not protect the most seriously ill patients. A new study reveals that a compound derived from fats found in fish oils prevents death in influenza-virus-infected mice, even at advanced stages of disease. The study offers a promising strategy for the treatment of patients with severe influenza virus infections.

Money talks when it comes to losing weight Posted: 07 Mar 2013 09:29 AM PST Weight loss study participants who received financial incentives were more likely to stick with a weight loss program and lost more weight than study participants who received no incentives, according to new research.

Majority of Albertans support assisted suicide, Canadian study shows Posted: 07 Mar 2013 08:07 AM PST New research gauges public opinion about assisted suicide as part of an ongoing legal, moral and health policy discussion in Canada.
