Agent could guide more precise removal of brain tumors
Scientists have created a nanoparticle contrast agent, consisting of a dye-coated gold core with a crust of silica, that highlights tumor margins during brain surgery. Researchers tested the agent in mice with glioblastoma tumors. Using a handheld Raman scanner, they found clusters of cancer that were not detectable with normal light or a Raman microscope. Details of the study appear in the journal ACS Nano. Chemical & Engineering News (8/25)

SPECT/CT imaging useful for guiding back pain treatment, study finds
A study that reviewed data from 29 patients with low back pain revealed that SPECT/CT data changed management in 76% of patients and could rule out the possibility of infection and distinguish joint and discogenic pain. Details of the study will be discussed at the Royal College of Radiologists Annual Scientific Meeting in London. Diagnostic Imaging (8/25)

Compound targets enzyme in brain cancer
Scientists have developed a neuraminidase inhibitor, targeting an enzyme that is highly expressed in some types of cancer. Researchers found the compound halted growth and appeared to convert glioblastoma cancer stem cells into healthy cells, suggesting the compound has properties that may be used to develop treatments to fight the disease. The study appeared in the journal Cell Death & Disease. Counsel & Heal (8/23)
