How the brain's backup system compensates for stroke

...nsation for neuronal interference, the adult brain exploits pre-established patterns of functional specialization. When a key node in an information-processing circuit is impaired, healthy cortical networks can flexibly reconfigure processing in a way that is rapid, functionally-specific, and preserves behavi...

LIAI scientists make important finding on cytomegalovirus transmission

...tal Medicine in a paper entitled, "Cytomegalovirus exploits IL-10-mediated immune regulation in the salivary glands." LIAI scientists Ian Humphreys, Ph.D., Carl Ware, Ph.D., and Michael Croft, Ph.D. led the study. CMV is a virus that affects the majority of the world’s population, but produces little or no ...

Danish researches solve virus puzzle

.... The researchers have investigated how a virus exploits the machinery of human cells to produce the proteins which the virus needs in order to replicate to billions of new vira. The virus penetrates into the host cell where it liberates its RNA which is a copy of the heritage material, DNA. RNA is like a ...

SARS: No evidence that any of the treatments worked

...hers, led by Rikard Holmdahl from Lund University, exploits a new finding in a mouse model that lack of reactive oxygen species makes arthritis worse rather than, as had been expected, better in a mouse model with arthritis. Reactive oxygen species are thought to be important in defense against pathogens. The...

Nanotech tools yield DNA transcription breakthrough

...erial version of the machine; our applied research exploits those vulnerabilities." One of the studies reported in Science was conducted by Ebright's laboratory in conjunction with Shimon Weiss' laboratory at the California NanoSystems Institute of the University of California-Los Angeles (UCLA). The stud...

Cell wall of pneumonia bacteria can cause brain and heart damage

...ule on the bacteria's cell wall, resembles PAF and exploits this similarity to bind to PAFr. The researchers demonstrated the role of PAFr by injecting fragments of S. pneumoniae cell wall into normal mice as well as mice that lacked the gene for PAFr (Pafr-/- mice). None of the regular mice survived after...

NYU algorithm enhances ability to detect cancer genes

...ore function. Their algorithm is unique in that it exploits the high resolution of gene-chips and prior biological models through Bayesian statistics in order to optimally pinpoint the genes involved in the cancer, even when these genomes may have many other unrelated deletions, which happen as "collateral da...

DOE JGI finishes 100th microbial genome

... barkeri fusaro, a methane-producing organism that exploits a unique metabolic pathway to do the job. This microbe, while isolated from a fresh water mud sample, also lives in the rumen of cattle where cellulose and other polysaccharides are digested. "We are delighted that the DOE JGI's 100th genome is a m...

New MRI technique quickly builds 3-D images of knees

...d of imaging cartilage. However, Block's technique exploits the difference in resonant frequencies between fat and water. During the scan time, then, the technique maximizes each component of the image, so that a technician can view any aspect. High-resolution 3-D images are important not only from diagnost...

Research details how a virus hijacks cell signals to cause infection

...ack door" approach to evade natural barriers, then exploits biological signals to infect human cells. Broadening knowledge of how viruses cause infection, a new study describes elaborate methods that the virus has evolved to bypass the body's defenses. "This study helps to explain how group B coxsackieviruse...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units

...to create a molecular complex (supramolecule) that exploits cisplatins tumor targeting to deliver a light activated drug. The latest results from the group's research to create a DNA targeting, light activated anticancer drug will be presented at the 231st American Chemical Society national meeting in Atlant...

UCLA scientists reveal how Nipah virus infects cells

...the National Biodefense Research Agenda, the virus exploits a protein essential to embryonic development to enter cells and launch its attack. The online edition of Nature reports the findings July 6. "In its natural state, the Nipah virus can be used as a potential bioterrorism agent capable of devastating ...
