Investigational antisense medicine lowers disease burden, reduces myeloma cell abundance in mice

Many patients with multiple myeloma, a type of blood cancer, eventually develop resistance to one treatment after another. That's in part because cancer stem cells drive the disease -- cells that continually self-renew. If a therapy can't completely destroy these malignant stem cells, the cancer is likely to keep coming back.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.
