Does Google AdSense hurt MSN rankings?

I am ranking well in MSN, but am wondering if I should implement AdSense

Does anyone know if MSNs algorithms include decreasing rank for sites who support competing ad revenues?

Using AdSense on your web site will NOT hurt your ranking in anyway. I have over ten web sites that all use AdSense and each one ranks number one or two for their main keywords in MSN search results.

I use Adsense and I think MSN has been fair to me in the SERPS.
