A tumor grade reflects how likely it is to grow and spread. In general, this is what those grades mean: Grade 1: Low grade, or well-differentiated: The cells look a little different than regular ...
That’s what researchers at Apnimed hope. Apnimed is a company that’s developed a new oral drug for sleep apnea – currently called AD109. AD109 combines the drugs aroxybutynin and atomoxetine ...
