Jumping gene could provide non-viral alternative for gene therapy

... it's the only way to go because viruses have been killing people," says Dr. Moisyadi, who has avoided viruses in his transgenesis studies. "One of our next goals is to use transposons to deliver a radio-protective gene, called manganese superoxide dismutase, to potentially protect normal tissue from radi...

Different strategies underlie the ecology of microbial invasions

...e bacteria of two distinct microbial mechanisms of killing competitors: through the release of chemicals (for example, antibiotics or bacteriocins) and through the release of parasites (for example, bacterial viruses, known as phages). Focusing on the second mechanism in an experimental setting, the research...

Researchers map spread of pathogens in the human body

...ns. Some antibiotics and vaccines are better at killing bacteria outside of the cells; others are more effective at killing infections within the cells. By understanding where bacterial pathogens hide in the body and how th...

Innovative movies show real-time immune-cell activity within tumors

...ssues, making direct contact with tumor cells, and killing them. Insights from this new view of the body's on-board defenses against cancer may open the way for improved immunotherapies to treat the disease. With a series of movies made under different experimental conditions, the researchers resolved im...

Experimental vaccine protects mice against deadly 1918 flu virus

...as the most deadly flu outbreak in modern history, killing 50 million or more people worldwide. "A key to containing pandemic flu viruses is to understand their vulnerabilities and determine whether they can evade immune recognition," says Dr. Nabel. "What we learn about the H1N1 virus that caused the 191...

For crickets, parasitic flies can stop the music

...ek and then tear their way out in "Alien" fashion, killing the cricket as they emerge. Now, University of Florida zoologists have found that the danger posed by the flies has apparently affected when crickets sing. In experiments with Southeastern U.S. field crickets, known scientifically as Gryllus ruben...

... in our own backyard. That kind of complacency is killing people and it has to stop. This plan of action shows us the path forward to reversing this national disparity." "The U.S. government is showing leadership in addressing the global pandemic, but we are failing to confront AIDS here at home," said ...

Hope for major advance in fighting world killer disease

...use of dysentery - are the most deadly in terms of killing children. They cause only 20% of cases of diarrhoea but result in 60% of deaths. It is these two killers - EPEC and Shigella - that the Leicester-led project is targeting. Peter Williams, Professor of Microbiology in the Department of Genetics...

Technology exists to keep E. coli out of food

Using this technology, the team had identified glycosylation structures that significantly improved an antibodies ability to kill cancer cells compared to the same antibody manufactured using mammalian cell culture. "By en...

Researchers develop technologies to devour food pathogens

...sults have shown the gas to be highly effective at killing microbial pathogens. The largest obstacle remaining is optimizing the system to dispense the appropriate amount of chlorine dioxide, Morgan said. Enough of the gas must be deployed to kill the pathogens, but too much can cause a decrease of quality i...

Natural anti-viral enzyme helps keep cancer cells alive, researchers find

... however, a balance would have to be found between killing cancer cells and compromising a patient's ability to fight disease. UT Southwestern researchers are now looking for chemicals that block TBK-1. They are also screening cancer cells for similar biochemical pathways essential to their survival but n...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

... the surface of the virus and start the process of killing it. This works well for many diseases, such as smallpox, polio and measles, but is much less effective with influenza, as the coat of the flu virus is continually changing. Vaccination against one strain of flu, for instance H3N2, is totally ineffe...

British cattle give TB to badgers, finds UC Davis expert

The controversial practice of killing wild badgers to prevent tuberculosis in cattle is unlikely to succeed, according to a newstudy led by Rosie Woodroffe, an ecologist at the University ofCalifornia, Davis, and a member of Britain's Independent Scientific Group on Cattle TB. In Britai...
