FLASH irradiation, an emerging cancer treatment that delivers radiation at ultrahigh dose rates, has been shown to significantly reduce acute skin toxicity in laboratory mice compared with conventional radiotherapy. Having demonstrated this effect using proton-based FLASH treatments, researchers from Aarhus University in Denmark have now repeated their investigations using electron-based FLASH (eFLASH).

A photothermal, nanoparticle-based deep brain stimulation (DBS) system has successfully reversed the symptoms of Parkinson’s disease in laboratory mice. Under development by researchers in Beijing, China, the injectable, wireless DBS not only reversed neuron degeneration, but also boosted dopamine levels by clearing out the buildup of harmful fibrils around dopamine neurons. Following DBS treatment, diseased mice exhibited near comparable locomotive behaviour to that of healthy control mice.

Biomedical microrobots could revolutionize future cancer treatments, reliably delivering targeted doses of toxic cancer-fighting drugs to destroy malignant tumours while sparing healthy bodily tissues. Development of such drug-delivering microrobots is at the forefront of biomedical engineering research. However, there are many challenges to overcome before this minimally invasive technology moves from research lab to clinical use.

The American College of Radiology (ACR) Learning Network introduced its first two vendor partners, Inflo Health and Radloop, to its ImPower program. ACR ImPower connects health systems and radiology practices with resources, expertise, and a structured approach to identifying, training, and supporting multidepartment quality improvement (QI) teams. The program combines QI education with the direct application of QI tools to projects for team analytical problem-solving, according to the ACR.

FLASH radiotherapy is an emerging cancer treatment that delivers radiation at extremely high dose rates within a fraction of a second. This innovative radiation delivery technique, dramatically faster than conventional radiotherapy, reduces radiation injury to surrounding healthy tissues while effectively targeting malignant tumour cells.
