Background: The aim of this study was to develop methods for cryopreservation and long-term maintenance of putative bovine embryonic stem cells (ESCs). Materials and Methods: Putative bovine ESC (bESC) lines (n=3) isolated in conventional medium were used to compare slow-freezing and vitrification. Results: After warming, vitrified cells (96.9%) demonstrated significantly (p<0.05) better surviv...
three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
