LIAI scientists make major finding on potential smallpox treatment

... protecting society against a smallpox outbreak by identifying an antibody in humans that quickly fights the smallpox virus. "This is a very important finding because it has the potential to be an effective treatment for smallpox in humans and therefore could help quickly stop a smallpox outbreak," said Mitch...

Learning how SARS spikes its quarry

...ts cells. The information could also be helpful in identifying potential weak points that can be exploited by novel antiviral drugs or vaccines. The SARS (severe acute respiratory syndrome) coronavirus was responsible for a worldwide outbreak in 2002-2003 that affected more than 8,000 people and killed 774 bef...

Skull study sheds light on dinosaur diversity

...son restudied the skulls and found characteristics identifying them as skulls of titanosaurs, a late surviving sauropod lineage. "Titanosaurs, which were surprisingly common at the end of the dinosaur era, were really the only sauropod lineage that flourished. All the others went extinct," said Wilson, an assis...

Study charts origins of fear

...ory that fear memory develops in that region. "By identifying NR2B in the pre-frontal cortex of the brain, we propose that fear memory originates from a network of receptors, rather than one simple area," Zhuo says. "It is more complex than previously thought." The next step, according to Zhuo, is to determine...

New technique could alter field of mouse genetics

...s bodes well for its use in mutating genes and for identifying unrecognized genes in places of the genome that have been especially difficult to sequence. Furthermore, the markers it carries make it easy to find. In Xu's lab, the jumping gene carried red fluorescent protein and an enzyme that changes the coat co...

Modification of program enables prediction of gene transcription

...he protein-coding region of the gene. By correctly identifying UTRs, we can avoid labeling them incorrectly as part of the protein-coding region," said Brent, who, with various colleagues, developed both TWINSCAN and N-SCAN. "It's important to know these two areas. Some of the signals that regulate transcription...

U-M researchers identify new blood test for prostate cancer

...te cancer. The 22-biomarker test was reliable at identifying prostate cancer even in the PSA ranges of 4-10 ng/ml or 2.5-10 ng/ml, intermediate PSA scores that do not always suggest cancer. The study authors suggest the 22 biomarkers could be used for patients in this range to help determine whether to undergo...

Unweaving amyloid fibers to solve prion puzzles

...urnal Nature. "They solve the important problem of identifying the intermolecular contacts that hold the amyloid fiber together." Amyloid fibers are often composed of prions--proteins that misfold and recruit neighboring proteins to misfold as well, a process that Lindquist calls a "conformational cascade." Whe...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

...t the MRI-MNP imaging technology may be helpful in identifying people at immediate risk of developing autoimmune diabetes, but most of all for early prediction of response to therapy, which might be very useful for reducing the time and cost of clinical trials.

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...ly, there are three diagnostic tests available for identifying respiratory viruses like RSV. The "gold standard" involves incubating an infected sample in a tissue culture for five days and then using a fluorescent dye to test for the presence of the virus. The main problem with this technique is that the virus ...
