Chronic Stress Can Impact Response to Radiation Therapy for Cancer, Roswell Park Study Suggests

Radiation is one of the oldest and most common therapies for cancer, and typically is delivered locally, or to specific targeted sites in the body. While it has long been thought that locally-delivered radiation therapy typically does not help to shrink tumors outside the field of irradiation, new preclinical research from a team at Roswell Park Comprehensive Cancer Center suggests a strategy for significantly increasing both the local and distant, or “abscopal,” effects of radiation. Results of the study, which was led by Elizabeth Repasky, PhD, have been newly published in Nature Communications.

Most Rehabilitating Sea Turtles with Infectious Tumors Don’t Survive

Fibropapillomatosis (FP) is the most significant infectious disease affecting sea turtle populations worldwide. FB leads to tumors on the turtles’ eyes, flippers and internal organs and is widespread in warmer climates like Florida. A large-scale study evaluated tumor score, removal and regrowth in rehabilitating green sea turtles with FP in the southeastern U.S. from 2009 to 2017, and found that 75 percent did not survive following admission into a rehabilitation facility, irrespective of whether or not tumor regrowth occurred after surgery.

Better Biosensor Technology Created for Stem Cells

A Rutgers-led team has created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders. The technology, which features a unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic material (RNA) involved in turning such cells into brain cells (neurons), according to a study in the journal Nano Letters.
