DNA packaging discovery reveals principles by which CRC mutations may cause cancer Posted: 17 Nov 2012 03:46 PM PST A new discovery concerning a fundamental understanding about how DNA works will produce a "180-degree change in focus" for researchers who study how gene packaging regulates gene activity, including genes that cause cancer and other diseases.

Anxiety linked to chest pain in children Posted: 17 Nov 2012 03:46 PM PST Psychological factors can have as much -- or more -- impact on pediatric chest pain as physical ones, a new study found recently. Psychologists discovered pediatric patients diagnosed with non-cardiac chest pain have higher levels of anxiety and depression than patients diagnosed with innocent heart murmurs -- the noise of normal turbulent blood flow in a structurally normal heart.

Daycare linked to being overweight Posted: 17 Nov 2012 03:46 PM PST Young children who attend daycare on a regular basis are 50% more likely to be overweight compared to those who stayed at home with their parents, according to a new study

Wandering minds associated with aging cells: Attentional state linked to length of telomeres Posted: 17 Nov 2012 03:45 PM PST Scientific studies have suggested that a wandering mind indicates unhappiness, whereas a mind that is present in the moment indicates well-being. Now, a preliminary study suggests a possible link between mind wandering and aging, by looking at a biological measure of longevity.

Is the detection of early markers of Epstein Barr virus of diagnostic value? Posted: 16 Nov 2012 01:11 PM PST Epstein-Barr virus (EBV) is the cause of infectious mononucleosis and a risk for serious disease in liver transplant recipients. Molecular tests that can identify early protein markers produced by EBV may have value for diagnosing active infection.

Hepatitis C treatment's side effects can now be studied in the lab Posted: 16 Nov 2012 01:10 PM PST Adverse side effects of certain hepatitis C medications can now be replicated in the lab, thanks to a research team. The new method aids understanding of recent failures of hepatitis C antiviral drugs in some patients, and could help to identify medications that eliminate adverse effects. The findings may aid the development of safer and more effective treatments for hepatitis C and other pathogens such as SARS and West Nile virus.

Exercise benefits found for pregnancies with high blood pressure, researchers say Posted: 16 Nov 2012 01:10 PM PST Contrary to popular thought, regular exercise before and during pregnancy could have beneficial effects for women that develop high blood pressure during gestation, a human physiology professor said.

Reconsidering cancer's bad guy Posted: 16 Nov 2012 09:46 AM PST Researchers have found that a protein, known for causing cancer cells to spread around the body, is also one of the molecules that trigger repair processes in the brain.

Teenagers urged to exercise to ward off bone disease Posted: 16 Nov 2012 09:45 AM PST Playing soccer or running for at least three hours a week could help teenagers counteract the potential damage to their bone health caused by prolonged spells of sitting.

Gene distinguishes early birds from night owls and helps predict time of death Posted: 16 Nov 2012 09:45 AM PST New research shows that a gene is responsible for a person's tendency to be an early riser or night owl -- and helps determine the time of day a person is most likely to die.

Improving quality of life for the bedridden: Textile pressure ulcer prevention Posted: 16 Nov 2012 05:55 AM PST Immobile patients are in constant danger of developing pressure ulcers on the skin. Medical researchers have worked together to develop a special sheet that is gentle on the skin and helps to make patients more comfortable.

Planning meals help people with diabetes enjoy the holidays Posted: 16 Nov 2012 05:52 AM PST A figurative mine field of savory dishes and desserts await many this holiday season, from pumpkin pies topped with whipped cream, green bean and mushroom casseroles, pork tamales, cranberries and cornbread dressing to fruit salads and oven-roasted turkey. Experts warn that while most will indulge in these tasty foods and some will gain weight, people with diabetes will need a plan to stay healthy during the holidays.

Mechanism of breathing muscle 'paralysis' in dreaming sleep identified Posted: 16 Nov 2012 05:52 AM PST A novel brain mechanism mediating the inhibition of the critical breathing muscles during rapid eye movement (REM) sleep has been identified for the first time in a new study.

Sports-related injuries requiring surgery on the rise among high school athletes Posted: 16 Nov 2012 05:51 AM PST As the nearly 8 million U.S. high school students who participate in sports every year suit up this season, scientists are encouraging them to focus on something more valuable than winning – their health. New research shows fracture and ACL prevention programs are essential in ensuring injuries don't sideline players.

Protein tug of war points toward better therapies for cardiovascular disease Posted: 15 Nov 2012 10:35 AM PST Two proteins are in a tug of war that determines how much the body makes of superoxide, a highly reactive and potentially destructive product of oxygen that's dramatically elevated in cardiovascular disease, researchers report. Their finding indicates an antiulcer drug just may help the body reduce excessive levels.

Asthma is not linked to lower educational attainment Posted: 15 Nov 2012 10:34 AM PST Having asthma is not linked to poorer scores in national school examinations, a new study shows. In contrast, ethnicity and social deprivation were associated with poorer educational outcomes in the study.

A new way of looking at Prader-Willi Syndrome Posted: 15 Nov 2012 10:33 AM PST An Australian study reveals that people with the rare genetic disorder known as Prader-Willi Syndrome may have an impaired autonomic nervous system. This discovery opens up a new way of looking at the insatiable appetite experienced by all sufferers, as well as their very high risk of cardiovascular disease.

Plant derivative, tanshinones, protects against sepsis, study suggests Posted: 15 Nov 2012 10:33 AM PST Researchers have discovered that tanshinones, which come from the plant Danshen and are highly valued in Chinese traditional medicine, protect against the life-threatening condition sepsis.

Dietary glucose affects the levels of a powerful oncogene in mice Posted: 15 Nov 2012 10:31 AM PST In this study, researchers help establish the mechanisms of why a low carbohydrate diet slows tumor growth in mice. The findings do not mean that cancer patients should cut back on the sugar in their diets, but it does pose questions about the consequences of diet on increased activity of an oncogene that drives tumor growth.

Influenza curbs part of immune system and abets bacterial infections Posted: 15 Nov 2012 10:31 AM PST When infected with influenza, the body becomes an easy target for bacteria. The flu virus compromises the capacity of the host's immune system to effectively fight off bacteria. Now immunologists have discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome -- and signals scavenger cells of the immune system to ingest fewer bacteria.
