Proteasome activator enhances survival of Huntington's disease neuronal model cells

...h HD model and patient cells. These remarkable results demonstrate for the first time that it is possible to intervene therapeutically in the proteolytic pathways and organelles that participate in the specific degradation of misfolded and abnormal proteins. ...

York mathematician probes geometric route to combat viruses

... from the University of Durham, she has used these results to model the assembly of viruses. Subsequent work with collaborators Professor Peter Stockley, Dr Neil Ranson and their groups at the Astbury Centre for Structural Molecular Biology at the University of Leeds suggests that not only the geometry o...

Man's best friend lends insight into human evolution

...nate ones. "Taken together," Hare writes, "the results on chimpanzee cooperation and their use of social cues support the hypothesis that evolution in human social problem solving, much like that of dog social problem solving, occurred after changes in our species' social emotions lifted social constrain...

Researchers wake up viruses inside tumors to image and then destroy cancers

...erimental therapy, called lytic induction therapy, results in tumor death. As the first step in this study, researchers screened a wide variety of drugs to see if any of them could reawaken the virus. They were fortunate in that one of the genes that is expressed upon viral lytic induction is EBV's thymid...

It's never too late to get it back! Aging interrupted

...mans? says Professor Spindler who will present his results at the Society for Experimental Biology’s Main Meeting in Glasgow on Monday 2nd April. Previous research has show that mice can live up to 40% longer if they simply consume fewer calories, but a highly nutritious diet. Because people are not very ...

Rare cell prevents rampant brain activity

... ?is prevented from becoming over-activated. Their results show that a rarer cell type that links collections of pyramid cells ?called a Martinotti cell ?acts as a kind of safety device. When a Martinotti cell receives signals above a certain frequency, it responds by sending back inhibitory signals that mod...

Scientists see DNA get 'sunburned' for the first time

Rapid response was crucial to containing the 1918 flu pandemic

...but the effect was smaller. These conclusions--the results of systematic analyses of historical data to determine the effectiveness of public health measures in 1918--are described in two articles published online this week in the journal Proceedings of the National Academy of Sciences. “These important p...

Male owls pitch their hoots to advertise body weight to competitors

...ombination of approaches and vocal responses). The results show that male owls respond more strongly to the high-pitched calls that simulate lighter individuals, confirming that territorial males attend to pitch information advertising body weight in the calls of their competitors. The authors also found tha...

Tundra disappearing at rapid rate

...th the rapidly decaying Arctic ice cap. "These results are very relevant to the current debate surrounding climate change because they provide real evidence that vegetation change will be quite considerable in response to future warming, potentially transforming tundra landscapes into open spruce woodlan...

Stanford-led study closes in on genes that may predispose some people to severe depression

...d eventually, treatment possibilities. The team's results are reported in two papers that will be published in the February issue of the American Journal of Psychiatry. Levinson's group, comprising researchers from six universities, achieved this breakthrough by studying 650 families in which at leas...

Biodiesel study targets cleaner air, cleaner engines

...n widely used by farmers. It is hoped the research results ?expected in early May ?will help increase demand for biodiesel, which in turn will increase market opportunities for recycled materials and oils and give farmers the chance to grow some of their own fuel. Recent government announcements supporting r...

Heart failure: Intervention possibilities from imaging programmed cell loss

...ns left ventricular events," said Hofstra. "Our results indicate that heart muscle cell death is an active and ongoing process in heart failure, and that annexin imaging could possibly guide treatment for heart patients and be used to determine whether a treatment was working," said Hofstra, co-author of ...

Sandia researchers take new approach to studying how cells respond to pathogens

...r stains at a time in three dimensions. The end results of the imaging and protein analysis are large amounts of data that must be categorized and understood. Computational modeling is then used to develop network models from experimental data and predictive modeling generates hypotheses to be tested next...

Out-of-body experiences may be caused by arousal system disturbances in brain

...port, "Out-of-body experience and arousal." The results are intriguing, and show that some people's brains already may be predisposed to these sorts of experiences. They found that an out-of-body experience is statistically as likely to occur during a near death experience as it is to occur during the tra...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

The company will also soon be starting an additional Phase IIb trial with the same candidate in South Africa. The Joint United Nations Programme on HI...

Jefferson scientists find rabies-based vaccine could be effective against HIV

...hod used is technically possible. He says that the results indicate the need for future studies in larger groups of animals, and that these currently are underway. In addition, one key question remains unanswered: Is such a rabies-based vaccine feasible as an HIV vaccine in humans? ...
