A system for the directed evolution of the insecticidal protein from Bacillus thuringiensis.

Theoretically, the activity of AB-type toxin molecules such as the insecticidal toxin (Cry toxin) from B. thuringiensis, which have one active site and two binding site, is improved in parallel with the binding affinity to its receptor. In this experiment, we tried to devise a method for the directed evolution of Cry toxins to increase the binding affinity to the insect receptor.

[Ruptured aneurysm of distal posterior inferior cerebellar artery located at caudal loop].

We report an unusual case of subarachnoid hemorrhage (SAH) due to ruptured aneurysm originating at the caudal loop of posterior inferior cerebellar artery (PICA). The patient was a 77-year-old female presented with a sudden onset of headache and vomiting. Initial CT scan demonstrated a SAH with thick hematoma mainly in the cisterna magna.
