A common blood test for triglycerides – a well-known cardiovascular disease risk factor – may also for the first time allow doctors to predict which patients with diabetes are more likely to develop the serious, common complication of neuropathy. 

Triglycerides are a type of lipid, or fat, that the body makes from calories it doesn't need immediately. Triglycerides are stored in fat cells until they are needed to provide energy. When higher-than-normal amounts circulate in the blood, a person is at higher risk of cardiovascular disease. 

In a previous article here I considered from a statistical standpoint the signal of Omega_b candidate decays extracted by the DZERO collaboration in a large dataset of proton-antiproton collisions -the ones produced by today's most powerful hadron collider, the Tevatron at the Fermi National Accelerator Laboratory.

A recent study of adult neural stem cells suggests a new route for research and development of  treatments for neurodegenerative disease in elderly patients.

Within the last 20 years neuroscientists have shown that new neurons are generated in the brain throughout the lifespan. This finding opened a new area of research aimed at understanding if adult neural stem cells can be used in therapies for neurodegenerative diseases.

A challenge with this approach is that there are fewer neural stem cell in the aged brain and the loss of stem cells occurs at just the time when neurodegenerative diseases are most common. But a new study is providing important information that neural stem from an aged brain still have the capacity to mature into functional neurons.

Astronauts blazed through their third of five spacewalks Saturday as they continued servicing the Hubble Space Telescope, installing the new Cosmic Origins Spectrograph (COS) and repairing the main science camera of the Advanced Camera for Surveys (ACS) which has been disabled since February 2007.  Initial tests verified that both instruments were alive and able to communicate with ground control.

Some pregnant women do not wear seat belts due to fear that the belt itself could injure the baby in a car crash.  Urban myth or legitimate concern?

It is well established that seat belts save lives but if some pregnant women do not wear seat belts out of fear that the belt could harm the baby in a car crash, are they really helping or just placing themselves in danger?    It's difficult to fault mothers for erring on the side of caution when it comes to unborn babies but is it actually the case that the seat belt can put the baby at risk?

Could sleep be a critical component to maintaining a healthy body weight?    Studies on subjects like this tend to have correlation arrows that point in all kinds of directions but new research presented on Sunday, May 17, at the American Thoracic Society's 105th International Conference in San Diego, says body mass index (BMI) is linked to length and quality of sleep in a surprisingly consistent fashion. 

As part of the Integrative Cardiac Health Project at Walter Reed Army Medical Center, researchers analyzed the sleep, activity and energy expenditures of 14 nurses who had volunteered for a heart-health program at the Walter Reed, where the nurses were employed. The program included nutritional counseling, exercise training, stress management and sleep improvement. 

A new study using advanced cardiac imaging technology indicates that cardiac abnormalities experienced by some marathon runners following competition are temporary, and do not result in damage to the heart muscle. The study, conducted by researchers at the University of Manitoba, marked the first use of cardiac magnetic resonance imaging, or CMR, in a post-marathon setting.
