Rapid response to kids' stroke symptoms may speed diagnosis Posted: 02 Jul 2015 03:38 PM PDT A rapid response plan for children at a hospital quickly identified stroke and other neurological problems. One in four children with stroke-like symptoms were diagnosed with stroke and 14 percent were diagnosed with other neurological emergency conditions, the study states.

Infection with Wolbachia bacteria curbs fighting among fruit flies Posted: 02 Jul 2015 01:11 PM PDT Male fruit flies infected with the bacterium, Wolbachia, are less aggressive than those not infected, according to research. This is the first time bacteria have been shown to influence aggression.

The sting in dengue's tail Posted: 02 Jul 2015 12:13 PM PDT Scientists have identified how small changes in dengue's viral genome can affect the virus' ability to manipulate human immune defenses and spread more efficiently.

Novel HIV vaccine regimen provides robust protection in non-human primates Posted: 02 Jul 2015 12:12 PM PDT A new study shows than an HIV-1 vaccine regimen, involving a viral vector boosted with a purified envelope protein, provided complete protection in half of the vaccinated non-human primates (NHPs) against a series of six repeated challenges with simian immunodeficiency virus (SIV), a virus similar to HIV that infects NHPs.

Vaccines and treatment for dengue virus possible Posted: 02 Jul 2015 11:23 AM PDT Researchers have determined the structure of a human monoclonal antibody which, in an animal model, strongly neutralizes a type of the potentially lethal dengue virus.

Viral protein in their sights Posted: 02 Jul 2015 10:27 AM PDT A team using electron cryomicroscopy has for the first time revealed at the atomic level the structure of a protein required for viral replication in vesicular stomatitis virus, a virus that is a model for a group of RNA viruses that includes Ebola and other threats to human health.

Telomeres linked to origins of idiopathic pulmonary fibrosis Posted: 02 Jul 2015 10:23 AM PDT Researchers have now discovered that telomeres, the structures that protect the chromosomes, are at the origin of pulmonary fibrosis. This is the first time that telomere damage has been identified as a cause of the disease. This finding opens up new avenues for the development of therapies to treat a disease for which there is currently no treatment.

Commonly prescribed drugs affect decisions to harm oneself and others Posted: 02 Jul 2015 10:23 AM PDT Healthy people given the serotonin-enhancing antidepressant citalopram were willing to pay almost twice as much to prevent harm to themselves or others than those given placebo drugs in a moral decision-making experiment. In contrast, the dopamine-boosting Parkinson's drug levodopa made healthy people more selfish, eliminating an altruistic tendency to prefer harming themselves over others.

Can autism be measured in a sniff? Posted: 02 Jul 2015 10:22 AM PDT Imagine the way you might smell a rose. You'd take a nice big sniff to breathe in the sweet but subtle floral scent. Upon walking into a public restroom, you'd likely do just the opposite -- abruptly limiting the flow of air through your nose. Now, researchers have found that people with autism spectrum disorder don't make this natural adjustment like other people do.

Working out in artificial gravity Posted: 02 Jul 2015 10:15 AM PDT Engineers have built a compact human centrifuge with an exercise component: a cycle ergometer that a person can pedal as the centrifuge spins. The centrifuge was sized to just fit inside a module of the ISS. After testing the setup on healthy participants, the team found the combination of exercise and artificial gravity could significantly lessen the effects of extended weightlessness in space -- more so than exercise alone.

Review indicates where cardio benefits of exercise may lie Posted: 02 Jul 2015 08:20 AM PDT A systematic review of 160 clinical trials of the cardiometabolic benefits of exercise shows which health indicators improve most with physical activity and for whom. For example, some of the benefits are greater for men, people under 50 and among those battling type 2 diabetes or other cardiovascular conditions.

Digesting bread and pasta can release biologically active molecules Posted: 02 Jul 2015 07:42 AM PDT Biologically active molecules released by digesting bread and pasta can survive digestion and potentially pass through the gut lining, suggests new research. The study reveals the molecules released when real samples of bread and pasta are digested, providing new information for research into gluten sensitivity.

Cause of acute liver failure in young children discovered Posted: 02 Jul 2015 07:41 AM PDT Acute liver failure is a rare yet life-threatening disease for young children. It often occurs extremely rapidly, for example, when a child has a fever. Yet in around 50 percent of cases it is unclear as to why this happens. Now, researchers working on an international research project have discovered a link between the disease and mutations in a specific gene.

Authors raise concerns about industry dominance in diabetes research Posted: 01 Jul 2015 06:45 PM PDT Diabetes research is dominated by a small group of prolific authors, raising questions about the imbalance of power and conflict of interests in this field, argue experts in a new article.

End pharmacists' monopoly on selling certain drugs, argues British expert Posted: 01 Jul 2015 06:45 PM PDT Evidence is lacking that having a category of drugs that can be sold only by pharmacists or under their supervision ('pharmacy medicines') has benefits, writes a pharmacy professor in a new article.

Make no bones about it: Female athlete triad can lead to problems with bone health Posted: 01 Jul 2015 12:23 PM PDT Participation in sports by women and girls has increased from 310,000 individuals in 1971 to 3.37 million in 2010. At the same time, sports-related injuries among female athletes have skyrocketed. According to a new study, women with symptoms known as the 'female athlete triad' are at greater risk of bone stress injuries and fractures.
