Dear Janet & list mates: I am very optimistic about stem cell research..... but.... some of these articles bring some underlying questions to mind: Do we know what actually kills our natural brain cells in the first place? If not, what's to prevent the new stem cells from dying a similar death soon after being implanted in the same environment? Using chemicals to induce P&D-like symptoms in test animals does not create the environment that's killing the cells in the first place. Don't get me wrong! I still want to be among the first to get a stem cell implant! I'm just trying to get my self up to speed on the state of the art.....;-) Luv t'all, Bill - PWP New Joisey PS - Two ladies were overheard at the luncheon: "Do you have a steady boyfriend?"...."No...he has Parkinsons".... :-) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ janet paterson [[log in to unmask]]: PMID: 10996018: Anti-apoptotic activity of rasagiline -----Original Message----- From: janet paterson [mailto:[log in to unmask]] Sent: Saturday, February 03, 2001 7:50 PM To: [log in to unmask] Subject: PMID: 10996018: Anti-apoptotic activity of rasagiline Mechanism underlying anti-apoptotic activity of a (-)deprenyl-related propargylamine, rasagiline --SNIP --
