'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens
12-06-2006 · EurekAlert!Researchers in the Greene Infectious Disease Laboratory at Columbia University's Mailman School of Public Health and their colleagues in the WHO Global Laboratory Network have developed a new tool for pathogen surveillance and discovery -- the GreeneChip System. The GreeneChip is the first tool to provide comprehensive, differential diagnosis of infectious diseases, including those caused by viruses, bacteria, fungi or parasites.

- New 'GreeneChip' identifies multiple pathogens rapidly and accurately
12-07-2006 · EurekAlert!
An international group of researchers has recently developed a new technology for pinpointing pathogens. Called the "GreeneChip," this device consists of a glass slide onto which are attached nearly 30,000 pieces of genetic material taken from thousands of different viruses, bacteria, fungi and parasites. When human fluid and tissue samples are applied to the chip, these probes will stick to any closely related genetic material in the samples.

- Genomic variation easier to identify with UCSD/Brown software
12-22-2006 · EurekAlert!
Computer scientists at the University of California, San Diego, and Brown University have created a software system that more accurately detects "microinversions," mutations that consist of tiny sequences of reversed DNA. The software gives biologists a powerful new tool to study genomic variation between and within species. The system is explained in the online edition of the Proceedings of the National Academy of Sciences.

- Surfing the blues -- Internet questionnaire can accurately identify depression
04-10-2007 · EurekAlert!
The Internet offers a valuable opportunity for the public to screen themselves for depression. This is the conclusion of a study published today in BMC Psychiatry, which demonstrates that a Chinese online tool for assessing depression is both accurate and reproducible, and may offer a way to identify the growing number of people suffering from depression.

Mount Sinai researchers have discovered a new potential diagnostic tool that could provide clinicians with a much-needed window into the molecular activity of blood vessels. The findings, which could help identify patients at risk for heart attack and stroke, were published in the Jan. 16 issue of Proceedings of the National Academy of Sciences.

- UCLA scientists identify new genetic link to autism
01-10-2008 · EurekAlert!
UCLA scientists used language onset -- the age when a child speaks his first word -- as a tool for identifying a new gene linked to autism. The team also discovered that the gene is most active in developing brain regions involved with language and thought. Interestingly, evidence for the genetic link came from the DNA of families with autistic boys, not those with autistic girls.

- New diagnostic technologies offer non-invasive means
04-15-2007 · EurekAlert!
Molecular messages and signals circulating in blood or contained in cells lining the airway can identify early stage cancer, according to research reported today at the 2007 Annual Meeting of the American Association for Cancer Research. Scientists looking to apply basic science knowledge to medical practice are developing tests that diagnose, predict or monitor cancer risks, without invasive tissue sampling. Such tests could benefit all, particularly underserved populations, such as the poor, who often wait until symptoms appear before seeing a doctor.

- Jefferson neuroscientists show anti-inflammation molecule helps fight MS-like disease
11-11-2007 · EurekAlert!
An immune system messenger molecule that normally helps quiet inflammation could be an effective tool against multiple sclerosis. Neurology researchers at Jefferson Medical College have found that the protein interkeukin-27 (IL-27) helped block the onset or reverse symptoms in animals with an MS-like disease. The results suggest that IL-27 may someday be part of a therapy to temper over-active immune responses, which are thought to be at the heart of MS.
