In this case a 44-year-old man presented with headache, tinnitus, and an intraventricular hemorrhage, as seen on computed tomographic scans. Cerebral angiography showed a right moyamoya pattern and an ipsilateral dural AVF fed by branches of the external carotid artery and draining into the transverse sinus. This extremely rare coincidental presentation may have deeper pathogenic implications.The research into the pathogenesis of moyamoya disease has found a breakthrough with the proposal of a "Mechano-biological theory" of pathogenesis of this disease. A research group in southern India have proposed this unifying theory based on computational fluid dynamics studies and longitudinal data. This proposal unifies the pathogenesis of moyamoya disease and moyamoya syndromes described in literature under a single mechanism. References

This functionality is then converted to its ylide; condensation with acetaldehyde then leads to the vinyl derivative (3); deprotection then gives cefprozil. Semisynthetic oral cephalosporin consisting of ~90:10 Z/E isomeric mixture. References
