Dana-Farber researchers are already using these new insights in clinical trials of a cancer vaccine, GVAX, that previously has produced rare but dramatic responses in some patients with advanced melanoma. "We have just...

Brain-computer link lets paralyzed patients convert thoughts into actions

...nn added, "this is the strangest, most interesting surgery I've ever done. Not the technical stuff, but the data that we get from the neurons firing in different patterns when you're thinking in different ways. And seeing it is only the beginning." The system is constantly being improved. Next steps includ...

Promising cell protein may play role in infection and dry eye

Tumor wizardry wards off attacks from the immune system

...ays David C. Linehan, M.D., associate professor of surgery and a researcher with the Siteman Cancer Center. "The new findings show that tumors are directly responsible for the increase of T-reg cells and can attract T-reg cells to their vicinity. This could be one way for tumors to evade immune surveillance....

Failure of 'scout cells' may lead to cancer in transplant patients

... leader Anne M. VanBuskirk, assistant professor of surgery and an OSU Comprehensive Cancer Center researcher. If we can understand the mechanism, perhaps we can discover how to prevent this type of cancer in transplant patients. The incidence of this cancer varies according to the organ transplanted, o...

Wild vs. lab rodent comparison supports hygiene hypothesis

...ker, Ph.D., an assistant professor of experimental surgery and senior member of the study team. "On the other hand, rodents living in the wild are exposed to a wide variety of microbes and parasites, much like humans living in societies without modern health care and where hygiene is harder to maintain."

New genetic test for breast cancer

...d to the lymph nodes. The standard treatment is surgery to remove the tumor, plus radiation and hormonal therapy, which cures about 80 to 85 percent of patients. Adding chemotherapy can further reduce the risk of recurrence by about 25 percent, but it benefits only a small proportion of women. Currently...

With cochlear implants, earlier use leads to better speech

... Even when deafness is confirmed, the idea of head surgery for their baby makes many parents hesitate. And they may be daunted by the fact that a cochlear implant is forever -- the device destroys any residual hearing so that hearing aids are no longer an option.
