With endearing honesty and vulnerability, Raghava KK tells the colorful tale of how art has taken his life to new places, and how life experiences in turn have driven his multiple reincarnations as an artist — from cartoonist to painter, media darling to social outcast, and son to father.
Stem cells have been a focal point for hype and hope for years now. Besides healing horses and dogs, they have promising effects on diabetes, corneal blindness, even HIV. It’s pretty clear that they’re also the future of organ transplants. Just the news of a stem cell related development or patent will cause a biotech company’s stocks to soar. The FDA, which regulates all interstate drug sales and related clinical trials is not trying to keep Americans from these “miraculous” cures, it’s simply trying to make sure they are safe first. Apparently, that’s taking too long. Medical tourism agencies are starting to cater to those seeking stem cell treatments. Whether or not they are ready for widespread medical use, stem cell therapies are in high demand, not just in the US but around the world. It’s no longer a question of when we will have access to these treatments, it’s a question of how.
