Stubborn infection, spread by insects, is called
'The new AIDS of the Americas'

The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Chagas disease, caused by parasites transmitted to humans by blood-sucking insects, has been named "the new AIDS of the Americas" in a lengthy editorial published in PLoS Neglected Tropical Diseases. The authors argue that the dangerous spread of Chagas through this hemisphere somewhat resembles the early spread of HIV. Chagas is also known as American trypanosomiasis, because the bugs carry single-celled parasites called trypanosomes. More

New microscope uses rainbow of light to image blood cell flow
R&D Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as traditional blood test in real-time, simply by shining a light through the skin. This optical instrument is able to provide high-resolution images of blood coursing through our veins without the need for harsh and short-lived fluorescent dyes. More

Era of iatrogenic CJD transmission 'nearly closed'
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
After nearly 40 years of surveillance, no new sources of Creutzfeldt-Jakob disease (CJD) have been reported, and iatrogenic cases are dwindling in numbers, a new report shows. More

Flesh-eating disease can elevate from seemingly minor incident
CNN    Share    Share on FacebookTwitterShare on LinkedinE-mail article
VideoBrief When Percy von Lipinski pricked his hand on a pine needle while decorating a Christmas tree, he had no idea that the incident in 2008 would nearly cost him his entire hand – and perhaps his life. What seemed like an insignificant injury resulted in a flesh-eating disease from necrotizing fasciitis, the same condition that's responsible for two serious cases in the United States that have recently risen to prominence.

Designer flu
Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Unlike in the movies, news of the lab-made viruses was not delivered as a threat, and the scientists doing the work weren’t henchmen of an evil dictator or members of a shadowy terrorist organization. Instead, the researchers were on the good-guy team — respected academics investigating how a type of flu virus that typically targets birds might become contagious in people. More

High-def endoscope lets doctors 'resect and discard' more
colorectal polyps

Reuters via Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new Olympus endoscope, not yet commercially available, can diagnose small colorectal polyps with high confidence and nearly 96 percent accuracy, as judged against pathology results, a new study found. Standard practice now calls for every polyp to be removed and studied. But with polyp detection becoming increasingly common, the work can burden pathology units. More

How one strain of MRSA becomes resistant to last-line antibiotic
American Society For Microbiology    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have uncovered what makes one particular strain of methicillin-resistant Staphylococcus aureus (MRSA) so proficient at picking up resistance genes, such as the one that makes it resistant to vancomycin, the last line of defense for hospital-acquired infections. Researches said, "MRSA strains are leading causes of hospital-acquired infections in the United States, and clonal cluster 5 is the predominant lineage responsible for these infections." More

In wild animals, charting the pathways of disease
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Eco-immunology works to understand how disease spreads in wildlife populations — the bighorn sheep are in trouble because of pneumonia that spread from domestic sheep — and how it can be worsened by human and environmental factors like climate change. Another major goal is to understand the pathways that deadly diseases can follow from wildlife to humans. In the last 30 years, more than 300 infectious diseases in humans originated in animals, including AIDS, Ebola, SARS, Lyme, hantavirus, West Nile virus and new strains of flu.

Powerful new approach to attack flu virus
Infection Control Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An international research team has manufactured a new protein that can combat deadly flu epidemics. The paper, featured on the cover of the current issue of Nature Biotechnology, demonstrates ways to use manufactured genes as antivirals, which disable key functions of the flu virus, says Tim Whitehead, assistant professor of chemical engineering and materials science at Michigan State University.

Device may inject a variety of drugs without using needles
MIT News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The researchers say that among other benefits, the technology may help reduce the potential for needle-stick injuries, which occur 385,000 times a year, the Centers for Disease Control and Prevention estimates.

New target identified in rheumatoid arthritis battle
Medical News Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have now discovered the mechanism by which a cell signaling pathway contributes to the development of rheumatoid arthritis, which affects more than one million adults in the U.S. The study, published ahead of the print version of Nature Immunology, shows evidence that drugs that are being developed for diseases like cancer, could potentially be used to treat RA.

Scientists: Sperm gene discovery may lead to male birth control
CBS News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A male birth control pill might not be so far-fetched, now that Scottish scientists have uncovered a key gene essential for sperm development. The gene — called Katnal1 — is critical for sperm production because it enables sperm to mature in the testes. Thus, if scientists can somehow regulate this gene with a pill, sperm production will be stalled. More

Science journal produces a different kind of viral video
Technology Review    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A scientific journal dedicated to video – a medium seldom seen in peer-reviewed publications – has scientists increasingly including short video clips when they submit their manuscripts. The Journal of Visualized Experiments – JoVE for short – is an online journal where video is the main medium rather than a supplement. More
