Stable formulations of inactivated polio vaccine (IPV) could reduce cold-chain requirements and increase distribution of the vaccine to developing countries. Recently, significant improvement in thermal stability of IPV vaccines has been achieved by including urea in lyophilized formulations. In the present study, we investigated the effects of urea on recovery of potency of IPV after lyophilization and storage at 37°C and the correlation of potency recovery with key biophysical properties of IPV.

September 11, 2001 provides a vantage point for examination of questions that arise from looking at the interrelationship between current environment and intrapsychic life. Two cases are presented as a focus for discussing the interaction of the memorialized past and occurrences in present reality, the significance for an analysis of analyst and patient sharing the same experience, instigations to progress that a current event may provide and the ways in which communal experience influences intrapsychic life.
