Study shows hope for early diagnosis of Alzheimer's

...ng brain activity, and turn it into a cutting-edge tool for diagnosing Alzheimer's disease," Kounios added. The team members hope that eventually they or other researchers will develop a hand-held device that can be used to conduct similar evaluations as those done by the Rowan/Penn//Drexel group. “...

Scientists find method to pick noncompetitive animals, improve production

...of Animal Sciences geneticist. The new method is a tool that may contribute both to animal well-being and ...more animals to be domesticated, Muir said. The tool makes it possible to design selective breeding programs to effectively reduce competitive interactio...

Scripps research study reveals structural dynamics of single prion molecules

...ce resonance energy transfer is a highly sensitive tool used to measure molecular structure and dynamics such as in single proteins at the angstrom level, a measurement unit used to define molecular distances (a 10th of a millionth of a millimeter). Fluorescence correlation spectroscopy is a high resoluti...

...ey commented, show that "FC MRI is a promising new tool for the investigation of brain-behavior relationships in patient populations. It makes no demands on the subject other than holding still and possibly maintaining fixation and therefore can be acquired even in patients that cannot perform a task?This...

Researchers urge monitoring of bone health during chemotherapy

... in breast cancer patients. "We used G-CSF as a tool to understand the implications for tumor growth when osteoclast activity is revved up," Weilbaecher says. "But G-CSF isn't unique in its effect. For example, antihormone therapies used to treat breast and prostate cancer also can decrease bone minera...

Bats prey on nocturnally migrating songbirds

...til recently. Stable isotopes could be a promising tool for unravelling their furtive ecology. For now, Eurasian songbirds should mind not only the Mediterranean Sea and the immensity of the Saharan desert, with their harsh winds and storms, when engaging into their transcontinental journeys at night; ...

New research shows that flu is a trigger of heart attacks

... preventable. Therefore, our results give us a new tool for preventing heart attacks. "My public health message is that flu is an important killer in cardiac patients. If people can recognise that the flu vaccine has specific cardioprotective effects, then high-risk people will be more likely to make s...

Penn study on lung-infecting bacterial enzyme suggests new approach to cystic fibrosis treatment

... their membrane. These oocytes are an experimental tool that allows the researchers to assess the flow of ions across the membrane by measuring electrical current. The researchers found that direct exposure of the CFTR-containing oocytes to SMase of Staphylococcus aureus and Bacillus anthracis bacteria sh...

Scientists map key landmarks in human genome

...cleosomes throughout the human genome. The mapping tool could help uncover important clues for understanding and diagnosing cancer and other diseases, the scientists say. Moreover, it may shed light on the role of nucleosomes in the process of "reprogramming" an adult cell to its original embryonic state,...

New test for most virulent HPV strains under study

... not become widely accepted as a primary screening tool for women age 30 and older, he says, citing cost and the tradition of Pap smears as likely factors. “This new HPV test could lengthen the interval of screening for cervical cancer. If the new test is as good as the old one and if the HPV test is n...

Tiny clue reveals new path toward heart disease

... Genetics. "Our discovery could lead to a clinical tool for assessing a person's risk of coronary artery disease, so that physicians can try to prevent the disease from progressing." The team, which includes researchers from several universities in the United States and the United Kingdom, reports its ...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...ibed in the literature and the PhosphoMotif Finder tool allows any researcher to find potential phosphorylation sites in any protein of interest. “The power of this technique is not just in the numbers,?says Pandey. “Rather, we’ve found what you might call new information about old proteins, and we ho...

Neural bottleneck found that thwarts multi-tasking

...ation in these regions. While fMRI is an excellent tool for identifying a particular area in the brain involved in a given task, it generally provides limited information about how that area responds over time. To overcome this limitation, Dux and Marois rapidly sampled brain activity using fMRI while...

Ultrathin films deliver DNA as possible gene therapy tool

...iversity of Wisconsin-Madison are now developing a tool to tackle this problem. David M. Lynn and his colleagues have created ultrathin, nanoscale films composed of DNA and water-soluble polymers that allow controlled release of DNA from surfaces. When used to coat implantable medical devices, the films...

Scientists reveal structure of gateways to gene control

...tibodies that bind only to this H2A.Z protein as a tool for separating all these promoter nucleosomes from the other parts of the yeast's DNA. Next, the team used a state-of-the-art DNA-sequencing machine to identify, or "read," the sequence of base-pair building blocks along the DNA of each of the H2A.Z...
