Wine-based antioxidantmay shield against radiation
What could be better? A little wine, a littlecheese-with a side of radiation protection.University of Pittsburgh researchers arestudying the radiation protective propertiesof resveratrol, a natural antioxidant commonlyfound in red wine and many plants.
What could be better? A little wine, a little cheese-with a side of radiation protection. University of Pittsburgh researchers are studying the radiation protective properties of resveratrol, a natural antioxidant commonly found in red wine and many plants.
Dr. Joel Greenberger and colleagues at Pitt's Center for Medical Countermeasures Against Radiation found that resveratrol,when altered with acetyl, shielded mouse cells from the effects of radiation. Greenberger's group had already made news in 2004 when it discovered the agent JP4-039, which can be delivered directly to mitochondria to resist radiation-induced cell death.
Greenberger's team released its latest findings on acetylated resveratrol at the 2008 American Society for Therapeutic Radiology and Oncology meeting in Boston.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
