Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

..., have found that biomarkers may able to assist in identifying infants who have a brain injury that might otherwise be missed and who would benefit from additional evaluation with a head computed tomography (CT) scan. Identifying cases of SBS that might otherwise be missed has important implications for decreasi...

Researchers use dirt to stay one step ahead of antibiotic resistance

... study of bacteria found in dirt may be the key in identifying how and why antibiotic resistance happens in bacteria that infect people, predicting future clinical problems, and testing new antibiotics. Antibiotic resistance has become an increasing public health concern because the organisms that cause infecti...

U of MN researchers identify ataxia gene

...of the different types of ataxias vary greatly, so identifying the specific type of ataxia provides patients with a more accurate picture of what the future holds. Ranum added: "Finding the SCA5 mutation in Lincoln's family makes it possible to test Lincoln's DNA ?if it becomes available ?to unequivocally deter...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...vidence to build their case -- as opposed to first identifying a suspect through other evidence and then using DNA to confirm their case. Some critics claimed that this practice could snag an innocent person, but Roeder has demonstrated through her own research that the likelihood of a false hit are miniscule --...

Screening blood for West Nile virus

...r (during the mosquito season) was as effective at identifying contaminated blood samples as screening throughout the year. These results suggest that a modification of the current policies would save large costs without significantly increasing the risk for blood recipients. Korves and colleagues also propose...

Terahertz imaging may reduce breast cancer surgeries

...is technology could aid the surgeon in immediately identifying residual cancer after the main tumor has been removed, thus minimizing the need for additional surgical procedures." Currently, excised tissue samples must be sent for histopathologic examination, which typically takes several days. Thus, surgeons d...

Minimal genome should be twice the size, study shows

...ium with desired metabolic properties, for example identifying which genes would a bacterium need to efficiently digest specific waste chemicals. The research has been supported by the Hungarian Scientific Research Fund, EMBO, the Human Frontier Science Program, DFG and the Biotechnology and Biological Sciences...

Largest study of human 'interactome' reveals a novel way

...ons between proteins in our cells hold promise for identifying new genes involved in genetic diseases, according ...disorders offers a novel approach for more rapidly identifying new candidate genes involved in human diseases," he says. The analysis included interactions among...

Parents need to be educated about HPV vaccinations for daughters

...of cytology has become an established strategy for identifying women at risk of developing cervical cancer and has been responsible for a dramatic fall in incidence and death rates. Vaccination programmes will still require some form of screening to be in place either for unvaccinated women or for women who dev...

Scientists develop protein-sequence analysis tool

...o control function. Biochemists are interested in identifying "active sites" -- regions of proteins that determi...his suggests that CPDL will have broad utility for identifying amino acid residues likely to play a role in distinguishing protein classes," Shanklin said. Scient...

New nanosensor uses quantum dots to detect DNA

...e Materials. "Conventional methods of finding and identifying samples of DNA are cumbersome and time-consuming," said Jeff Tza-Huei Wang, senior author of the paper and supervisor of the research team. "This new technique is ultrasensitive, quick and relatively simple. It can be used to look for a particular pa...

Stress substantially slows human body's ability to heal

...Behavioral Medicine Research. The work is aimed at identifying and then explaining the ways psychological stress can affect human immunity. Jan Kiecolt-Glaser, a professor of psychiatry and psychology, and partner Ronald Glaser, a professor of molecular virology, immunology and medical genetics, both at Ohio S...

Bees solve complex colour puzzles

... the surfaces in a scene are under the same light, identifying a particular surface when the global illumination changes is in principle an easy problem to solve, since all vision needs to do is adapt itself to the scene's average colour, a bit like adapting to the darkness of a cinema. Far more difficult is to ...

ASU researchers 'wire' DNA to identify mutations

...te for the first time, the possibility of directly identifying these mutations, or single nucleotide polymorphisms (SNPs), by means of measuring the electrical conductance of a single DNA molecule. SNPs are buried in the 3 billion DNA bases of the human genome. On average, SNPs occur about once in every 1,00...

Mutations in the BRAF gene predict sensitivity to a novel class of cancer drugs

... called the Cancer Genome Project, has the goal of identifying the causative mutations that cause human cancers. "This represents what we believe will be the first of a series of new drugs that specifically target cancer cells that contain mutations identified by the Cancer Genome sequencing effort," said Dr. S...

New study identifies key gene in development of connections between brain and spinal cord

...owever, there is still much research to be done in identifying the key target genes in the brain. Fezl is another critical step in piecing together a complete picture of brain and spinal cord development." ...

Genes involved in biofilms

.... The first, following the usual methods, involved identifying mutants that had lost the capacity to form biofilm, thus enabling identification of the essential genes and positive regulators of the process. The results showed that a positive regulator known as Pnp (Polynucleotide phosphorylase) exists and which ...

Finding the mind's eye

...tanding of the brain's interaction with the eye by identifying the neural basis of conscious experience, a relationship important to the fields of medicine, neurology and psychology. Tse and his co-authors, Susana Martinez-Conde, Alexander A. Schlegel and Stephen L. Macknik of the Barrow Neurological Institute,...

Finding rewrites the evolutionary history of the origin of potatoes

...ugh the mountains of South America, collecting and identifying wild potatoes and researching them. "When researchers discover an important trait - for example, that a certain species is resistant to disease - then everything related to that species becomes potentially useful," Spooner says. "We can scree...

Adult stem cells aid recovery in animal model of cerebral palsy

... Drosophila, in which scientists have also started identifying “speciation genes,?should tell us if similar genes are employed repeatedly in different genera during the formation of new species. ...
