This newly-identified DNA aptamer, representing as the first molecular probe reported capable of recognizing a protein dimer, could serve as an important tool to uncover the mystery of this particular protein dimer in a biological context.

Methods All the 15 cases of ICCAAns underwent the direct microsurgery via the carotid artery-cavernous sinus space approach. Results Immediate carotid arteriography after the surgery showed that the aneurysms disappeared and the carotid artery could be showed clearly and normall. In a follow up period ranged frcm 1 months to 9 years,it was showed that,among 5 cases with 333,IV,V a,VI nerve paralysis before the surgery, three completely recovered,one recovered incompletely. All patients regained the capability of undertaking mormal cativities. None experienced rebleeding or neuroparalysis. Conclusion Direct microsurgery via this is approach is an ideal treatment of ICCAAns. 6 refs.展开更多
