...utic agents often has adverse effects on patients, noninvasive diagnostic tools to determine their need are essential for effective management of the disease. The new technique proposed here examines how bones respond to vibrations of various frequencies, with healthy bone responding differently to weak bone. Jo...Imaging study provides new information on how the brain processes sounds of different tones
...cal studies of repetition rate in humans have used noninvasive techniques for probing brain function, such as evoked potential and evoked magnetic field measurements. A limitation of this line of research is that the sites of response generation cannot always be reliably localized. Evoked magnetic field examina...Sandia pursues biotechnology as new technology focus area
...search. Among the first were an insulin pump and a noninvasive glucose monitor. Others included a bio-cavity laser, prosthetics, decontamination foam and the Rapid Syndrome Validation Project (RSVP). But no concerted effort existed to use this new technology in a big way. In 1999 John and Romig sponsored a study...Leading cancer research organization urges FDA to speed approval of drugs for precancers
...evel." Today, however, emerging technologies for noninvasive imaging are increasing the number of lesions that can be detected and identified at an early stage. The development of the gene chip, for example, is allowing scientists and clinicians to measure specific cancer-related genomic changes in patients u...Dartmouth researchers identify multi-tasking circadian protein
...ht or whether our discovery can be exploited for a noninvasive medical therapy," Dunlap says. "But, if you want to do therapy--antifungal, antibacterial or anything--you start looking for biochemical activities that the host does not have that can be targeted to the pathogen." Froehlich, working with Dunlap and ...18F-FDG PET predicts lymphoma treatment outcome
... converting food to energy--PET provides accurate, noninvasive detection and staging of many cancers. A radiopharmaceutical, such as 18F-FDG (fluorodeoxyglucose), which includes a radionuclide (a radioactive element) is injected into the patient and gives off signals that are measured by a PET scanner. Because...New way found to see light through novel protein identified by Dartmouth geneticists
...nd to light or whether that can be exploited for a noninvasive therapy," Dunlap acknowledges. It may be a long shot, but drug therapies start with properties people don't have. "If you want to do therapy--antifungal, antibacterial or anything--you start looking for biochemical activities that the host does not...Buffalo neuroimaging researchers studying multiple sclerosis from inside human brain
... suggest that this type of scan could be used as a noninvasive method to determine and monitor gray-matter tissue damage in MS patients. Fabiano has been awarded a prestigious research grant from the Alpha Omega Alpha Medical Honor Society to continue this work this summer in Bakshi's lab. Jitendra Sharma, M.D....HIV-like virus detected in wild chimpanzee
...the virus was critical to the studys success. This noninvasive test, developed by first author Mario L. Santiago, allowed the scientists to avoid having to capture the endangered animals to take blood samples. Of the tested animals only one -- a sexually active Pan troglodytes schweinfurthii male from the Gomb...Purdue leads center using pollution-busting plants, microbes
... industry and by community groups because they are noninvasive and low-cost." The EPA Hazardous Substance Research Center Program began in 1989. Purdue will replace two former centers that had been led by Kansas State University and the University of Michigan. "It was a fairly daunting task to go up against cent...University of Cincinnati and Air Force use algal enzyme to create new silicon-based materials
... Long-term applications of materials also include noninvasive cancer therapy, optical data storage and blue light lasers. Clarson noted that the worldwide market for silicon-based polymers is currently $10 billion a year. "So, there are many applications with potential for major economic impact," he said....Using brain activity to identify risk for disorders
...their risk for developing alcoholism can undergo a noninvasive measure of brain electrical activity called P300 event-related potential (ERP), one of the few brain measures associated with risk for alcoholism. A study in the September issue of Alcoholism: Clinical & Experimental Research examines the variatio...Normal salt levels in the lung of the cystic fibrosis mouse
...rmal and CFTR-/- mice. The authors note that this noninvasive approach may be of use in the study of other lung diseases where the properties of the ASL has not been adequately studied....New $35.5 million center for mind, brain and learning created at UW
...in. Advanced brain mapping technology will permit noninvasive measures across the life span that will be linked to state-of-the-art behavioral measures. This will permit brain and behavior measurements in the same individual and across time. Nature-nurture - Advances in genetics and behavioral science will al...Study suggests diabetics can use light to measure glucose
...feel is the first comprehensive demonstration that noninvasive measurements can be made with infrared light," Small says. Now that they know the technique works, the research team plans to improve the performance of the method. Small estimates the technique could be ready for commercial use in three to five ye...University of Florida scientist maps brain reactions to food
