Hi Jessie

Glad that article was of use - you're clearly far more knowledgeable on the specific medical terminology than I am - I can usually manage to decipher the basic gist of most abstracts - enough to know if they may be relevant or not - but the heavy technical stuff is often beyond me - your explanation helped clarify it some more. That's what I love about this website - everyone's willingness to share and learn from each other.
