Unraveling Alzheimer's: Clues may be found visualizing plaques in human brain, mad cowtype diseases
SAN DIEGO, Calif.--An exciting new tracer allows visualization of abnormal protein deposits-...s 53rd Annual Meeting in San Diego. "This amyloid tracer IMPY--which detects amyloid plaques in the human brain--provides an excellent starting point for par...Getting ahead of cancer: SPECT/Spiral CT technology enhances bone scanning, earlier diagnosis
...abolism rather than changes in bone structure. The tracer usually requires several hours to be absorbed into the bone and cleared from the remaining tissues of the body. By evaluating the images taken at different times after the administration of the tracer, information about bone metabolism and blood flow...Patients to benefit from novel technology revolutionizing high-speed molecular imaging
... San Diego. "The potential of using more than one tracer and more than one isotope simultaneously means that more than one medical condition can be searched in one go--ultimately improving the diagnosis of cancer, heart and brain diseases," explained James A. Patton, professor of radiology and physics with...New clues to how major weight-loss drugs work
...known to regulate the body's energy balance. Their tracer experiments showed that receptors for serotonin are, indeed, expressed on particular neurons in this circuitry that are potent modulators of food intake and body weight. What's more, the researchers found that both serotonin and drugs that affect ser...News tips from the Journal of Neuroscience
...a. The authors injected the GP with the retrograde tracer cholera toxin subunit b (CTb), and then co-immunostained the striatum for CTb and dopamine receptors or opioid peptides. Surprisingly, they found evidence of all four proteins in both pallidal areas. This pattern was not affected by the presence of p...Developing radiotracers for imaging studies in addiction
...T scanner picks up the radioactive signal from the tracer and continuously tracks its concentration and movement through the body. The data can be used to reconstruct three-dimensional images that reveal where the compound goes in the body/brain and how long it stays, for example.

...ng projections. Whereas in adults, the size of the tracer injection was nearly identical to that of its corresponding projection, in 1-week-old mice, the projections targeted a much broader area. The projection areas gradually refined to adult precision during the first 7 weeks of life. Interestingly, the i...PET imaging shows young smokers quick benefit of quitting
...y a cold pressor test by using PET with the oxygen tracer called 15O-water. Additional research is necessary, said Tamaki. "We would like to compare the current information with data from middle-aged smokers to see whether such response after smoking cessation may be seen in an older generation. Also, it wo...New clean-up project builds upon success gained in field

By injecting a viral tracer agent in various muscles, the researcher traced the cerebellar modules involved in the control of a single muscle. She then inactivated one of the modules by injecting a neurotoxin. The rat's ability to walk was scarcely altered but there was a stron...HIV protein enlisted to help kill cancer cells
...ology, they are linking the anticancer proteins to tracer molecules that selectively bind to cancer cells. "Dr. Mach designed tracers to visualize cancer in PET (positron emission tomography) scans," Hawkins says. "By binding our molecules to the tracers, we can deliver them to cancer cells. We've seen phen...Researchers wake up viruses inside tumors to image and then destroy cancers
...e, express TK, and only then could we use the FIAU tracer to make the cells light up," Pomper says. "So we were hoping to find a way to turn latent Epstein-Barr virus on in these cancers, and use the thymidine kinase it then produces to enable us to see the virus-associated tumors with radiolabeled FIAU." ...Bioluminescence at the service of a novel cerebral imaging technique
