neuroblastoma cells resistant to chemotherapy. Because fenretinide, a derivative of retinoic acid, targets a different molecular pathway--one that induces apoptosis, or programmed cell death--in neuroblastoma cells and is well tolerated, there has be...

of the most economically damaging plant diseases in the world. Compared with other fungicides, "rhamnolipid, because of its biological nature, has less toxicity and better biodegradability," said Raina M. Maier, a professor in UA's department of soil...
