UCLA scientists have identified a new mechanism that delivers a key substance that fuels the growth of pancreatic and prostate cancer cells, a finding that offers new hope in the fight against two of the deadliest forms of the disease.  The findings in the study, which was published online today in the journalPNAS, provide the first promising evidence that positron emission tomography (PET) imaging techniques and SGLT2 inhibitors could be used to better diagnose and treat pancreatic and prostate cancers , said Ernest Wright, professor of physiology in the David Geffen School of Medicine at UCLA and lead author of the three-year study. {read more here}

Researchers studied 600 rhesus monkeys [with PET} from a multi-generational family.  They measured anxiety-related behavior with structural brain imaging.  Scans revealed a brain circuit linked with anxiety is inherited.  Monkeys, like humans, can be temperamentally anxious and pass their anxiety-related genes on to the next generation. {read more here}

Researchers believe middle-life changes in key biomarkers of Alzheimer’s disease may predict who will develop dementia years later. Investigators from Washington University School of Medicine in St. Louis studied brain scans and cerebrospinal fluid of healthy adults for more than 10 years. They followed 169 cognitively normal research participants ages 45 to 75 when they entered the study. {read more here}

The use of interim PET/CT imaging has limited prognostic value to patients with diffuse large B-cell lymphoma (DLBCL) being treated with R-CHOP-14 (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone given every 14 days), the results of a large trial have indicated. {read more here}
