Scientists Receive Patent for Development of "combination" Proteins to Produce Vaccines for Lyme Disease

...id Dunn. Moreover, by incorporating unique protein fragments from various pathogenic families of Borrelia, these chimeric proteins could be used to distinguish clinically important exposure to disease-causing Borrelia from exposures to other non-pathogenic families of Borrelia. The patent covers the developm...

Rotavirus can Spread Beyond the Intestine

...rhea in children,// and who have antigens (protein fragments from the surface of the virus) in their blood, also have infectious virus in their blood. Margaret Conner and colleagues from Baylor College of Medicine, Houston Texas, tested samples obtained from hospitalized children with gastroenteritis and compa...

Shockwave Lithotripsy is Effective for Pediatric Urolithiasis

...ey called an insignificant less than 3-mm residual fragments of 15%. The re-treatment rate was 58%. The efficiency quotient was 47. They also found that stone size correlated with a stone free rate while patient age and stone location did not have a significant impact. The group concluded that shockwave lith...

DNA-damage Test Could Aid Drug Development

...ng an easily detected 'micronucleus' consisting of fragments of nuclear DNA. Unlike the current procedure, which injects the compound into a live mouse, the new assay is a cell-culture system that could allow hundreds or thousands of tests to be performed from the bone marrow of a single mouse, and potentially...

New Tumor Markers for Pancreatic Cancer

...ility to join complementary DNA. The organized DNA fragments contained on a microarray can detect all possible messages sent by the nearly 30,000 genes that exist in the human genome. When RNA is exposed to the microarray, each message binds to its matching DNA, producing fluorescent signal. These findings r...

Researchers Have Found the Role of Protein in Accelerating Breast Cancer Progression

...erent subtypes and new elastin synthesis. Collagen fragments are known to stimulate growth of carcinoma cells and to stimulate anti-apoptotic pathways, favouring growth of the carcinoma cells," he added. Other authors of the study, Secretion of Pleiotrophin Stimulates Breast Cancer Progression Through Remodel...

Genes Influence the Ability to Listen Two Things at a Time

...e-syllable words or nonsense syllables (short word fragments such as ba, da, and ka) were played into their right and left ears simultaneously, and then tried to name both words or syllables. In two other tests, volunteers listened to digitally altered one-syllable words played into the right ear and tried ...

Penguins Altered Diet When Humans Began Hunting Whales and Seals

...s began hunting seals and whales, ancient eggshell fragments reveal. According to Steven Emslie of the University of North Carolina in Wilmington, and William Patterson of the University of Saskatchewan in Saskatoon, it suggests that when humans removed krill-eating predators, the penguins exploited the res...

Completely Neutral Evolutionary Changes Helped Shape Our Genome

...s to the organism it inhabits. Repeat elements are fragments of DNA containing the same repetitive sequence of chemical base pairs several hundred times. "For a long time, the basic belief of evolution was that all random genetic changes that manage to stick around have some selective advantage. But our work...

Prions Prevent Alzheimers Disease

...g up amyloid protein into the smaller beta-amyloid fragments needed to build plaques. Further evidence for th...enetic forms of prion disease because beta-amyloid fragments are able to form when the normal prion protein is corrupted by genetic mutation. Professor Hooper ...

A new century of Alzheimer's disease research

...eakthrough came when the gene that produced the AB fragments (amyloid-beta precursor protein, or APP) was found on chromosome 21. This made sense, because patients with Down syndrome, all of whom inherit an extra chromosome 21, typically develop early brain plaques and tangles. Then scientists linked mutation...

Biologics valuable treatment option for patients with inflammatory bowel disease

...he literature on monoclonal antibodies or antibody fragments currently approved by the FDA or likely to be approved in the near future. The participants of the Consensus Development Conference, medical experts in IBD convened by the AGA Institute, sought to answer a series of questions about the treatment of I...
