Prototype just-in-time medical device enables untrained bystanders to save lives

...?even those with no emergency medical training ?to perform life-saving actions for victims of sudden cardiac arrest. The just-in-time support, or JITS, device provides bystanders with guidance and information on how to administer CPR and assess the state and needs of the victim. The researchers will present...

Male circumcision reduces HIV risk, study stopped early

...medical tools, equipment and supplies necessary to perform large numbers of circumcisions safely. "Already, there are large numbers of boys and young men who are seeking circumcision in areas of Africa where men are not traditionally circumcised," he said. "The danger is that unqualified practitioners wil...

Poor athletic performance linked to vitamin deficiency

...ollege athletes and other elite competitors -- may perform worse during high-intensity exercise and have a decreased ability to repair and build muscle than counterparts with nutrient-rich diets, according to recent Oregon State University research published in the International Journal of Sport Nutrition an...

Hope for major advance in fighting world killer disease

...nts to clinical professors, had the opportunity to perform the tests with their own hands and see the results with their own eyes. They were very impressed!" In the developing world it is not possible on cost grounds to give antibiotics to every child with diarrhoea, and in any case antibiotics would not wo...

Older men treated for early prostate cancer live longer than those who are not

...e analysis of existing data, the researches had to perform extensive statistical adjustments to account for study participants differences. Even with all these differences taken into account, there was still a significant improvement in the overall survival of those men who received active treatment. "This b...

Regulating the nuclear architecture of the cell

... What other functions abundant heterochromatin may perform are still an open question. Even epigenetics ultimately has its roots in the genes; the researchers' first step was to identify which genes affect organization of the heterochromatin, then to identify the proteins expressed by these genes, and fi...

Evolution and the workaround

...es, and they do this by evolving new mechanisms to perform old tasks. Somehow the bad guys find a workaround. That observation led Norman Pavelka, Giulia Rancati, and Rong Li, researchers at the Stowers Institute for Medical Research in Kansas City, MO, to step back and consider the basic process by whic...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...than their maximum capacity, and only occasionally perform very long dives. By limiting dive duration, seals maintain aerobic metabolism, avoid lactate buildup that occurs in the face of insufficient oxygen and require little time to recover, Folkow explained. Seals often spend 80-90% of their time at sea un...

Artificial cornea offers better results for infants, some blind patients

...n, successful transplants can be more difficult to perform than in adults. "The vibrancy of a child's immune system has been one of the main reasons why cornea transplants haven't worked well in children," said Gearinger. "The risk of rejection is huge, and it just goes up with every subsequent operation....

MIT material stops bleeding in seconds

...er visibility during the operation. "The time to perform an operation could potentially be reduced by up to 50 percent," said Ellis-Behnke. Unlike some methods now used for hemostasis, the new materials can be used in a wet environment. And unlike some other agents, it does not induce an immune response ...

GlycoFi and Dartmouth report full humanization of yeast glycosylation pathway in Science

...mammalian cell culture. "By engineering yeast to perform the final and, most complex step of human glycosylation, we are now able to conduct far more extensive structure-function investigations on a much wider range of therapeutic protein targets," Dr. Gerngross commented....

First major study of mammalian 'disorderly' proteins

... and confirmed that most of these unruly molecules perform critical functions in the cell. The St. Jude team completed the first large-scale collection, investigation and classification of these so-called intrinsically unstructured proteins (IUPs), a large group of molecules that play vital roles in the dail...

Mysterious 'neural noise' actually primes brain for peak performance

...ggest mysteries; why it's so noisy, and how it can perform such complex calculations. As counter-intuitive as it sounds, the noise seems integral to making those calculations possible. In the last decade, Pouget and his colleagues in the University of Rochester's Department of Brain and Cognitive Sciences...

Train your brain to hear your friends at a party

...imics a hearing loss. They then got the ferrets to perform the same task twice a day for two weeks and made a startling discovery. At first, the ferrets' ability to identify where the sound was coming from was dramatically reduced (because their spatial hearing had been disrupted by the earplug) but after tw...

Researchers identify neurons that assign value during learning

...t brain complexity, the fruit fly larva is able to perform such associative-learning tasks. Because of its neuronal simplicity and the fact that it can be genetically manipulated, the fruit fly offers a favorable study case to address a principal question in the field of learning and behavior: Which neurons ...

Genome archaeology illuminates the genetic engineering debate
