Just as France and Germany took an increasingly divergent stand with the United States over the Iraq issue, on January 3rd, 2003, eight countries including Britain, Italy, Spain, Portugal, Denmark, Poland, Czech Republic and Hungary made a joint statement in the British Times, appealing to Europe to act in concert with U. S. over the issue of using force against Iraq.

Exosomes （EXO） derived from dendritic cells （DC） and tumor cells have been used to stimulate antitumor immune responses in animal models and in clinical trials. However, there has been no side-by-side comparison of the stimulatory efficiency of the antitumor immune responses induced by these two commonly used EXO vaccines. In this study, we selected to study the phenotype characteristics of EXO derived from a transfected EG7 tumor cells expressing ovalbumin （OVA） and OVA-pulsed DC by flow cytometry. We compared the stimulatory effect in induction of OVA-specific immune responses between these two types of EXO. We found that OVA protein-pulsed DCOVA-derived EXO （EXODC） can more efficiently stimulate naive OVA-specific CD8^＋ T cell proliferation and differentiation into cytotoxic T lymphocytes in vivo, and induce more efficient antitumor immunity than EG7 tumor cell-derived EXO （EXOEG7）. In addition, we elucidated the important role of the host DC in EXO vaccines that the stimulatory effect of EXO is delivered to T cell responses by the host DC. Therefore, DC-derived EXO may represent a more effective EXO-based vaccine in induction of antitumor immunity. Cellular ＆ Molecular Immunology. 2006;3（3）：205-211.

The theoretical conditions for the bend development or attenuation have been reviewed and tested for a study reach of the Meghna river. The field observations in the natural alluvial meander do not support the theories developed for bend development. The limitations of the theory to apply in the natural meandering river are discussed.
