Immune system has evolved to prevent autoimmune disease

... be an immune system that responds faster and more effectively against disease."This should help us get well faster, so the question becomes, 'Why didn't we evolve that kind of adaptive response?'" Deem said. Deem's analysis falls within a branch of physics called statistical mechanics, which uses a system's ph...

New results validating Pall prion reduction filter disclosed at ISBT Congress

...iewed results of new studies that found the filter effectively reduced prions under a range of different blood processing conditions, which may vary by country and blood center. Allan Ross, President of Pall Medical, who opened the symposium, noted that concerns about vCJD are not limited to the UK and Europe, ...

Brain networks change according to cognitive task

... research presented in the Journal of Neuroscience effectively sets the stage for further development in our understanding of neuroscience. In their article, the Northwestern scientists provide evidence of the ways in which different cognitive goals are achieved from the interaction between different brain regio...

Fish and chips: A fast track to understanding blood development

...rom a single collection of umbilical cord blood to effectively treat adults and older children. This research provides insight into understanding how to stimulate blood stem cells to multiply so that scientists could generate enough cells from a single umbilical cord to treat more patients. Importantly, the res...

Study: Plants use dual defense system to fight pathogens

...ntists found that both of these effector molecules effectively shut down the PAMP pathway. But the plant's R-proteins detect this, and come to the rescue. "The R-proteins detect the insidious activity by which the pathogen's effectors block the PAMP pathway," Mackey said. "PAMP defense responses are probably of...

Infectious disease expert warns of spread of Rocky Mountain spotted fever

...ntially deadly impact of the disease, which can be effectively treated with specific antibiotics if caught early. "Rocky Mountain spotted fever is a dangerous and potentially fatal disease, unlike its more widespread cousin, Lyme disease, which is almost never fatal," he says. In the latest study, researchers a...

Virus uses tiny RNA to evade the immune system

...ound the target of the plentiful SV40 microRNA. It effectively targeted the messenger RNA for a protein known as T antigen, leading to its cleavage. "SV40 may be the world's most studied virus," Sullivan said, "and T antigen is its most studied part." When SV40 enters a cell, it produces T antigen, which functi...

Study charts origins of fear

...l be able to reduce levels of NR2B accordingly and effectively reduce fear memory. In the future, perhaps people can take therapeutic measures before experiencing a particularly discomforting situation." The University of Toronto Innovations Foundation is currently working with Zhuo to push for the translation ...

How HIV disables the cells' call for help

...nvolved in invoking a large-scale immune response, effectively shutting them down. From their new understanding of how a tiny virus can gain control of the body's immune response, the scientists made an intuitive leap. In autoimmune diseases, the same T cells that play host to HIV viruses are overactive, mistak...

Locusts' built-in 'surface analysis' ability directs them to fly overland

...a discovery that could pave the way for efforts to effectively combat this periodic scourge by controlling their natural inclination to fly over land rather than water. The desert locusts, known scientifically as Schistocerca gregaria, are able to swarm for great distances and in numbers measuring in the millio...

Columbia scientists develop cancer terminator viruses

...f immune modulating and toxic genes. These viruses effectively eliminate primary tumors and distant tumors (metastases) without harming normal cells or tissues. Dr. Fisher's cancer research team includes Columbia University Medical Center investigators: Drs. Zao-zhong Su (research scientist), Devanand Sarkar (a...

Newly Discovered Role for Heart Response Enzyme May Yield Better Heart Failure Therapy

...or inhibiting PI(3)K's enzymatic activity -- might effectively block heart receptor loss to maintain or restore normal heart function in those at risk or suffering from heart failure, he added. Collaborators on the study include Sathyamangla Naga Prasad, Arundathi Jayatilleke and Aasakiran Madamanchi, all of Du...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...r. "This work is a truly remarkable example of how effectively ants can manipulate their environment in order to promote their own survival," he adds. A devil's garden begins when a M. schumanni queen colonizes a single D. hirsuta tree, the authors write: "Over time, D. hirsuta saplings grow within the vegetat...

Newfound roadblock to interferon effectiveness against malignant melanoma

...a mechanism that blocks the ability of the drug to effectively inhibit growth. Confirming this initial finding, the researchers found that when they inhibited STAT5 in interferon-resistant melanoma cells, they were able to restore the effectiveness of interferon. This demonstrates the relevance of STAT5 and its...

Organic farms produce same yields as conventional farms

...nally produced crops. Organic farming can compete effectively in growing corn, soybeans, wheat, barley and other grains, Pimentel said, but it might not be as favorable for growing such crops as grapes, apples, cherries and potatoes, which have greater pest problems. ...

US Army plans to bulk-buy anthrax

...ven fears that they could be used to determine how effectively anthrax is dispersed when released from bombs or crop-spraying aircraft. "I can definitely see them testing biological weapons delivery systems for threat assessment," says Hammond. Whatever use it is put to, however, the move could be seen as highl...

Drug resistance testing in treatment-naive HIV patients is cost-effective

...al HIV diagnosis--before treatment is started--can effectively guide a physician's choice of treatment regimen and increase a patient's quality-adjusted life expectancy. (Quality-adjusted measurements of time reflect that survival with an illness is presumed to be of lower quality than healthy survival.) "For ...

Analysis of flower genes reveals the fate of an ancient gene duplication

...functions. Duplications are important because they effectively allow at least one of the gene copies to evolve while the (likely important) function of the original gene can remain intact. In this way, the duplication of pre-existing genetic information provides the raw material from which new gene functions can...

Secrets to antibody's success against West Nile Virus surprise scientists

...uding dengue fever. A monoclonal antibody that can effectively treat mice infected with West Nile virus has an in...re less effective at stopping infection could more effectively prevent the virion from binding to host cells. How does an antibody that's better at preventing t...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

...f medulloblastoma could enable researchers to more effectively disrupt the genes and proteins that fuel its growth. Stem cells are immature cells that have the potential to differentiate into multiple types of adult cells. They are known for their unique ability to proliferate extensively and give rise to both ...
