- High-normal uric acid linked with mild cognitive impairment in the elderly
01-01-2007 · EurekAlert!
Researchers at the Johns Hopkins and Yale university medical schools have found that a simple blood test to measure uric acid, a measure of kidney function, might reveal a risk factor for cognitive problems in old age. Of 96 community-dwelling adults aged 60 to 92 years, those with uric-acid levels at the high end of the normal range had the lowest scores on tests of mental processing speed, verbal memory and working memory.

- Blood test predicts mortality in hospitalized heart failure patients, says UCLA researcher
05-07-2007 · EurekAlert!
A simple blood test -- beyond standard lab tests -- taken at hospital admission strongly predicted in-hospital mortality risk for heart failure patients and may be useful in helping doctors decide which patients need higher-level monitoring and more intensive treatment.

- Lab on a chip developed at University of Alberta for cheap, portable medical tests
01-29-2008 · EurekAlert!
University of Alberta researchers have developed a portable unit for genetic testing about the size of a shoebox, which has the same capability as a lab full of expensive equipment. The device -- along with other, much smaller units the team is now in the process of developing -- paves the way for enormous savings to health care systems and will improve care for patients.

- Lab-on-a-chip could speed up treatment of drug-resistant pneumonia
11-14-2006 · EurekAlert!
A new lab-on-a-chip can identify single bacterial cells for the most common cases of drug-resistant pneumonia, cutting down the wait from days to hours for identifying the particular strain and treating it.

- Under-used colon cancer screening test is effective
09-25-2007 · EurekAlert!
New Kaiser Permanente study in Journal of the National Cancer Institute shows that an under-used fecal occult blood test specific for human blood is a better screening test for colon cancer than the stool screening tests most frequently used - the unrehydrated guaiac test and the sensitive GT -- because it finds more polyps and cancers. This new FIT test may help improve colon cancer screening rates and may be a popular alternative to colonoscopies.

- Lab-on-a-chip device from Berkeley Lab to speed proteomics research
05-02-2007 · EurekAlert!
Future proteomics research should see a substantial acceleration with the development of a new device that provides the first monolithic interface between mass spectrometry and silicon/silica-based microfluidic "lab-on-a-chip" technologies. This new device, called a multinozzle nanoelectrospray emitter array, was developed by scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).

- Undersea mission aids development of self-test for stress and fatigue
08-10-2007 · EurekAlert!
An undersea mission simulating the space environment is providing data for development of self tests to quickly assess stress, fatigue and cognitive fitness in preparation for performing critical mission tasks. The three-minute, handheld test measures vigilance, attention and psychomotor speed. The test is sensitive to fatigue and other factors that impact a person's ability to pay attention to a task and respond quickly.

- UT Health Science Center researchers decoding saliva to detect breast cancer
01-10-2008 · EurekAlert!
Researchers at The University of Texas Health Science Center at Houston can identify and quantify specific protein markers in human saliva to provide an early, non-invasive diagnosis of breast cancer, according to a study appearing today in the journal Cancer Investigation. The study is being applied to "lab-on-a-chip" technology that may bring this type of diagnostic test -- capable of detecting the presence of cancer before a tumor forms -- into everyday use.

- Fast test for low blood flow in dogs detects early heart trouble
11-12-2006 · EurekAlert!
Working with dogs and using the latest in imaging software and machinery, also known as a 64-slice CT scanner, Johns Hopkins heart specialists have developed a fast and accurate means of tracking blood that has been slowed down by narrowing of the coronary arteries. Researchers say it took them less than half the time of exercise stress tests and echocardiograms currently used to find early warning of vessels more likely to become blocked and cause heart attack.
