Most of amateur athletes undergoing hypoxic training are not advised by specialists Posted: 26 Jun 2015 07:51 AM PDT Physical performance after periods of hypoxic training -- in low-oxygen conditions -- has become a matter of growing controversy within the scientific community. An international study compared professional and amateur athletes' knowledge and understanding of this type of training According to the results, just 25 percent of amateurs are assessed and monitored by specialists.

3-D heart printed using multiple imaging techniques Posted: 26 Jun 2015 06:55 AM PDT Congenital heart experts have successfully integrated two common imaging techniques to produce a three-dimensional anatomic model of a patient's heart. This is the first time the integration of computed tomography (CT) and three-dimensional transesophageal echocardiography (3DTEE) has been used in this way. A proof-of-concept study also opens the way for these techniques to be used in combination with a third tool -- magnetic resonance imaging (MRI).

High blood pressure linked to reduced Alzheimer's risk, meds may be reason Posted: 26 Jun 2015 06:55 AM PDT People with a genetic predisposition to high blood pressure have a lower risk for Alzheimer's disease, new research suggests. However, authors conclude the connection may have more to do with anti-hypertension medication than high blood pressure itself.

Action spectrum of sun skin damage documented Posted: 26 Jun 2015 06:55 AM PDT Scientists have documented for the first time the DNA damage that can occur to skin across the full range of ultraviolet radiation from the sun providing an invaluable tool for sun-protection and the manufacturers of sunscreen.

Inactivity reduces people's muscle strength Posted: 26 Jun 2015 06:55 AM PDT It only takes two weeks of not using their legs for young people to lose a third of their muscular strength, leaving them on par with a person who is 40-50 years their senior, new research shows.

Key protein may affect risk of stroke Posted: 26 Jun 2015 05:41 AM PDT Studies on mice reveal that a special protein in the brain's tiniest blood vessels may affect the risk of stroke. Scientists are learning how the blood-brain barrier develops and what makes the capillaries in the brain different from small blood vessels in other organs.

Want to be seen as more loving and a better cook? Posted: 26 Jun 2015 05:39 AM PDT Do you want to be seen as a better cook and a more loving parent? It's as easy as serving a vegetable at dinner, according to recent research. Families are most likely to consume vegetables at dinner time, yet only about 23% of dinners contain a full serving of vegetables, the study discovered.

Exercising early in life yields rewards in adult years Posted: 26 Jun 2015 05:39 AM PDT What impact can exercise done early in life have on the propensity for exercising during the adult years? Researchers did experiments on mice in the lab to find out. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass -- results that may have relevance for the public policy debates concerning the importance of physical education for children.

Researchers uncover epigenetic switches that turn stem cells into blood vessel cells Posted: 26 Jun 2015 05:38 AM PDT A molecular mechanism that directs embryonic stem cells to mature into endothelial cells -- the specialized cells that form blood vessels -- has been discovered by researchers. Understanding the processes initiated by this mechanism could help scientists more efficiently convert stem cells into endothelial cells for use in tissue repair, or for engineering blood vessels to bypass blockages in the heart.

Online computer game can help shed weight, reduce food intake Posted: 26 Jun 2015 05:34 AM PDT A simple new computerized game could help people control their snacking impulses and lose weight. Psychologists report that participants lost an average of 0.7kg and consumed around 220 fewer calories a day whilst undergoing the week of training.

Rapid Ebola diagnostic successful in field trial Posted: 26 Jun 2015 05:34 AM PDT A new test can accurately diagnose Ebola virus disease within minutes, providing clinicians with crucial information for treating patients and containing outbreaks.

Emergency visits for childhood food allergy on rise in Illinois Posted: 26 Jun 2015 05:34 AM PDT Emergency room visits and hospitalizations of children with severe, potentially life-threatening food allergy reactions increased nearly 30 percent in Illinois over five years, reports a new study. Hispanic children, who previously had the lowest cases of food allergies, had the biggest increase with a 44 percent rise. This study shows severe food allergies are beginning to impact children of all races and income. It is no longer primarily a disease of children who are white and/or from higher income families.

These 'skins' are in: Students' designs give prosthetics a new look Posted: 25 Jun 2015 10:13 AM PDT Students have produced "skins" or covers for prosthetic limbs.

Development of new blood vessels not essential to growth of lymph node metastases Posted: 25 Jun 2015 10:11 AM PDT The growth of metastases in lymph nodes -- the most common site of cancer spread -- does not require the development of new blood vessels, researchers have discovered, potentially explaining why antiangiogenesis drugs have failed to prevent the development of new metastases.

Targeting nerve endings to curb allergic asthma Posted: 25 Jun 2015 10:09 AM PDT A study supports a surprising alternative approach to controlling asthma: targeting certain sensory nerve endings in the lungs. The researchers show that specialized sensory neurons called nociceptors are not only activated by allergic inflammation, but also exacerbate the allergic immune response. When these neurons are selectively silenced in mouse models of acute and chronic asthma, both inflammation and bronchial twitchiness are reduced.

Updated guidance on use of hepatitis C drugs Posted: 25 Jun 2015 10:01 AM PDT The online Recommendations for Testing, Managing, and Treating Hepatitis C has been updated to aid practitioners treating patients infected with hepatitis C virus (HCV). HCV is a blood-borne virus that infects the liver and may lead to cirrhosis or liver cancer (hepatocellular carcinoma). In the past 25 years HCV has gone from an undiagnosed disease to an epidemic level, with the World Health Organization (WHO) estimating that up to 150 million people worldwide live with chronic disease.
