Molecular imaging scientist shares Nobel Prize for Chemistry
Roger Tsien, Ph.D., addressed the media Oct. 8 after learning he would share the 2008 Nobel Prize for Chemistry with Osamu Shimomura, Ph.D., and Martin Chalfie, Ph.D., for the discovery and application of green fluorescent protein as a tagging tool in bioscience and molecular imaging.
Roger Tsien, Ph.D., addressed the media Oct. 8 after learning he would share the 2008 Nobel Prize for Chemistry with Osamu Shimomura, Ph.D., and Martin Chalfie, Ph.D., for the discovery and application of green fluorescent protein as a tagging tool in bioscience and molecular imaging. Shimomura isolated the protein from a jellyfish in 1961 as a researcher at Princeton University. Chalfie demonstrated at Columbia University that the fluorescing protein could tag intracellular material in a roundworm.
At the University of California, San Diego, Tsien engineered a series of mutations creating a palette of fluorescing molecular dyes (right) that have revolutionized small animal optical imaging and molecular pharmaceutical research. (Provided by UCSD)
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
