'Trojan Horse' agent halts bone metastasis in mice

...es of mice, investigators say it likely could help prevent the growth of other cancers in bones such as breast, multiple myeloma, lung and renal cell. "Many tumors invade bone in the same way, so these findings suggest it may be possible to shut down this process regardless of the tumor type," says the st...

Researchers discover that sheep need retroviruses for reproduction

...ally harmless and generally contain mutations that prevent them from producing infectious retroviruses," he said. However, several endogenous retroviruses appear to provide protection from infection and are involved in reproduction. For instance, the exogenous Jaagsiekte Sheep Retrovirus or JSRV causes lun...

U of S Vaccine and Infectious Disease Organization team discovers key step in flu virus replication

...s may help to develop new influenza treatments and prevent the disease, as well as add to global pandemic preparedness research." To survive, the influenza virus hijacks the host animal or human's cellular machinery and forces it to make more copies of the virus. The researchers believe that the cellular ...

Edge density key to controlling gypsy moth spread

...reshold." This would decrease edge populations and prevent the periodic surges of growth that expand the territory. Other invading species may also exhibit pulsed spreading. If researchers can determine that the Allee effect is in place, than this same plan of containment might aid in controlling a variety...

Male circumcision reduces HIV risk, study stopped early

...integrated with all the other things that we do to prevent new HIV infections, such as treating sexual transmitted diseases and providing condoms and behavioral counseling," Bailey said. "We can't expect to just cut off a foreskin and have the guy go on his merry way without additional tools to fight against...

Worms produce surprise insight into human fever

... pH, lytic enzymes, and antimicrobial peptides to prevent microbial colonization of the intestine. In dissecting two conserved pathways required for C. elegans immunity to bacteria, Aballay found a wealth of data on innate immunity plus a surprising insight into another classic metazoan response to in...

New HIV statistics indicate increasing toll of AIDS on African American community

Human stem cells delay start of Lou Gehrig's disease in rats

...on. Both groups of rats were treated with drugs to prevent transplant rejection. The rats were weighed and tested for strength twice a week for 15 weeks. Weight loss, according to Koliatsos, indicates disease onset. On average, rats injected with live stem cells started losing weight at 59 days and lived...

Friendly bacteria in alcoholic milkshake could fight food allergies

...rgies in young children. Kefir is also reported to prevent food antigens from passing through the intestinal wall. Liu believes that the milky drink could be a promising tool in the prevention of allergies. "In the future, maybe we can screen out the certain components (bacterial strains or bioactive pept...

Emergency contraception fails to halt abortions

... abortion in 1984 said they had used it to try and prevent the pregnancy, 6% of women had done so in 1996 and 12% in 2002. Emergency contraception has been heralded as the solution to rising abortion rates, says Professor Glasier, but in the UK, abortion rates have increased from 11 per 1,000 women aged 15...

UCSD researchers discover internal compass of immune cell

...s of anti-inflammatory drugs could be developed to prevent rheumatoid arthritis, inflammatory bowel diseases, asthma, and many other chronic inflammatory diseases," said Junger. Conversely, drugs that boost these amplification systems and the internal compass could be used to coax neutrophils to migrate t...

HIV exploits competition among T-cells

...strategy that the computer simulations suggest may prevent the final onset of AIDS. The research, which is slated for publication in Physical Review Letters, is available online at http://arxiv.org/abs/q-bio.PE/0610018 . "Competition among T cells exerts a small influence for most diseases, but it's fata...

Caterpillars tell us how bacteria cause disease

PNNL staff scientist and co-author Uljana Mayer devised new tagging methods that enabled the team to isolate sufficient amounts of protein. The tags also allowed fast measurements of protein-mineral ...

Quality not quantity important for immune response to HIV

...spite being first identified in 1981, a vaccine to prevent infection has so far proved elusive. When HIV infects the body, it hides out in so-called "helper T-cells". T cells play an important role in the immune response generated by the body to fight infection. There are a number of different types of T ...
