I just have to post congratulations to Team, who just got back from the US , he set up a trip to visit a Professor he met at a Toxicology Conference in China last year. The Professor works at Beth Israel Hospital in the Nephrology Dept. (Kidney Transplant Section) in Boston. Team obtained his 10yr. -US VISA and arranged to visit the Professor for 2 weeks at the hospital. Quite a accomplishment. Although we are not together anymore â€“ I sincerely wish him all the best in the future and I am sure he is capable and will be a ultimate success in what ever path he chooses to follow â€“ at the present time he is working on completing his theses for his Masterâ€™s Degree in Toxicology at CMU.
