MRSA use amoeba to spread, new research shows

...kind of pathogenic behaviour first evolved. A good example is the bacterium that causes legionnaires disease. Probably it was pathogenic long before humans and other animals arrived on the evolutionary scene. Even today, it has no known animal host". "The most likely reason is that Legionella and many pat...

Birth defects: 8 million annually worldwide

...n be made within existing health care systems, for example by training health care providers to use simple diagnostic and preventive tools that are available. In the past, the toll of birth defects in these countries has been underestimated for a variety of reasons, the report authors say. These include po...

Men and women differ in brain use during same tasks

...he psychiatric condition of major depression as an example of the psychological differences between men and women, because twice as many women as men have this condition. He added that there are many other psychiatric conditions in which the male and female ratio is not equal or in which males and females sh...

Scientists directly view immune cells interacting to avert autoimmunity

...d that much of the movement is quite directed, for example toward the dendritic cells, rather than random activity. These directed movements are followed by prolonged interaction between autoimmune T cells and dendritic cells that lead to proliferation of autoimmune cells and eventually tissue destruction. ...

A salty tale: New bacterial genome sequenced from ancient salterns

...s from neighboring archaeal species, in an unusual example of cross-domain lateral gene transfer. "Scientists are increasingly learning how microbes adapt to harsh environments," remarks Mongodin, first author on the PNAS study, funded by a grant from the National Science Foundation and United States Depar...

Access to existing medical treatments could save more lives than spending to improve the treatments

...need them. Woolf illustrated the concept with an example of a theoretical disease that claims 100,000 lives a year. If a drug is available that reduces the mortality rate from that disease by 20 percent, it has the potential to save 20,000 lives each year. But if only 60 percent of eligible patients receiv...

Setting the standard for computer models of life

...proach has worked very well for other fields - for example the microarray community, by enabling authors, publishers and data providers to work together to improve access to meaningful biological information." ...

Sooner is better with cochlear implants, Stanford scientist shows

...'ga' then it must have been 'da.'" Another classic example of the McGurk effect is that the sound "pa" combined with the lip movements for "ka" ends up being heard as "ta." It is impossible to hear the proper sound while viewing the speaker's lips, noted Knudsen. Knudsen and Fox wondered if children born de...

Researchers use 'trickery' to create immune response against melanoma

...from adequate." These results mark the first ever example of targeted drug delivery using nanoparticle-aptamer bioconjugates. Significantly, the drug delivery was highly specific. Uptake of particles was not seen to be enhanced in cells which did not express the PSMA protein, indicating a selective tumour-t...

...ent problem solvers to the table." Thesecould for example be tools for precise, natural genetic enhancements, using non-GM approaches (for example, homologous recombination), new plant breeding methods such as marker assisted selection, or even true breeding hybrids of crop species that would allow farmers ...

'Good' bacteria could save patients from infection infection by deadlier ones

...a solutions saturated with harmless bacteria - for example "bioactive yoghurt." The same approach, perhaps, should be applied to patients' tissues that are to be exposed to surgery. Admitting that his ideas may sound absurd to some, the fact is that MRSA has become widespread in hospitals - including in I...

Eisai announces Phase II data on E7389, a potential new therapy for the treatment of breast cancer

...cology at Eisai Medical Research Inc. "E7389 is an example of Eisai's human health care (hhc) commitment to satisfy unmet medical needs of patients and their families. Eisai has targeted oncology/critical care as one of three key therapeutic areas of focus," she added. Seventy-one women were enrolled in the...

Technique offers new view of dynamic biological landscape

...u begin with a process you're interested in -- for example secretion -- and look for all the genes that affect secretion. It's a productive approach, but it's very process oriented," he said. "You might find a given gene that's involved in secretion, but it doesn't tell you about the many other processes it ...

Chlamydia parasite lives off our fat

...t the recruitment of lipid droplets constitutes an example of 'organelle mimicry' where Chlamydia escapes recognition by the host by cloaking itself in these fat-rich structures." Understanding host lipid transport by Chlamydiae may have further implication for chronic infections, the researchers say. For ...

Bacteria that cause tooth decay able to survive without important biochemical pathway

...f Dentistry. "As far as we know, this is the first example of any bacteria that can cope without this pathway; all of the existing literature indicated it is vital." The signal recognition particle, or SRP, pathway is a primary mechanism by which proteins are chaperoned from cellular assembly lines, where t...

The brain is broadly wired for reproduction

...ively express. Then those genes can be used -- for example in gene knockout studies -- to determine what role the neurons play in reproduction and behavior," Buck said. "Understanding how the brain's neural circuitry controls behavior has been largely a black box," she said. "I think that through studies li...
