Philadelphia Researchers Found A Novel Way To Fight Several Kind of Cancers

...e, express TK, and only then could we use the FIAU tracer to make the cells light up," Pomper says. "So we were hoping to find a way to turn latent Epstein-Barr virus on in these cancers, and use the thymidine kinase it then produces to enable us to see the virus-associated tumors with radiolabeled FIAU." ...

New Guidelines For Assessing Lymphoma Treatment

...ique that uses radioactivity emitted from injected tracer chemicals to measure and image biological activity. The most commonly used PET radiotracer is fluorodeoxyglucose (FDG), a radiolabeled form of glucose, which is consumed more avidly by tumors than by normal tissue. In contrast to conventional compu...

RNA Nanotechnology To Rescue Cancer Patients In Future

...t is also important for the molecule to act like a tracer that can provide valuable information regarding the location and the outcome of treatment. Particles pass through cell membranes into the cell's interior, and the body has a hard time retaining particles smaller than 10 nanometers. But the tiny tria...
