New system translates improved diagnostic information to target radiation at tumors
...opy (MRS) and the latest techniques for delivering precise doses of radiation to tumors. The system can also compensate for how tumors change and shift between diagnosis and treatment, during treatment, between treatments and even as patients breathe. Based on advanced computer modeling, the image trans...Sealing corneal incisions with a drop of chemistry, BU researchers develop gel for cataract surgery

The researchers also will focus on developing precise islet cell-survival monitoring techniques, including contrast agents and probes, that will use real-time noninvasive magnetic resonance imaging of islet mass and function. This imaging technique will ultimately be able to be translated into human stu...The 23rd Congress of the European Society for Therapeutic Radiology and Oncology (ESTRO)

The gene silencing allows precise molecular characterization of targets that are relevant for therapeutic response while the imaging allows non-invasive assessment of drug activity towards implanted tumors. This approach saves time and money because it is possible to see the effects ...Rice cartilage experts win $1.5M NIH grant to bioengineer TMJ discs
...Americans suffer from TMJ disorders. Though the precise cause of many TMJ disorders remains a mystery, symptoms can range from minor and occasional pain due to clenching the jaw or grinding the teeth to severe, debilitating pain that requires hospitalization or surgery. Because the TMJ is essential for ba...Researchers find circulating tumor cells in long-term cancer survivors
... the body. Dr. Uhr said that there appears to be a precise balance between tumor cell replication and cell death. Those who stay healthy may have developed a way of keeping the size of the tumor cell population in check, making breast cancer a chronic illness in these patients, he said.
