Does Adwords participation affect organic rank?

I know this has been answered before but...

This is the most recent thread I can find on the matter (http://www.webmasterworld.com/forum81/3545.htm) but with Google's increasing reliance on their contentious quality score, I was wondering whether things had changed?

The questions posed on this thread were:
1. Do adwords ads on various search engines count as "links" when Google calculates PR or serp rank?
2. Do adwords ads on affiliate (content) sites count as "links" when Google calculates PR or serp rank?
3. Does the ctr for Google ads, if astronomically high, help a site's PR or serp rank?

The answer is still No to each of those questions.
