OBJECT Cerebral aneurysm is a major cause of subarachnoid hemorrhage, but the mechanisms of its development remain unclear. Mechanical stretch has been reported to induce vascular smooth-muscle cell apoptosis via endothelin B receptors (ETBRs). The objectives of this study were to clarify the expression and localization of ETBR in cerebral aneurysms and to(More)
BACKGROUND Recently it is reported that proliferative activity remains in vascular walls of cerebral arteriovenous malformations (AVMs). These reports indicate that endothelial cells in AVMs have the neoangiogenic property. In this study, we assess the role of thioredoxin-1 (Trx-1) and hypoxia-inducible factor 1a (HIF-1α) in AVMs. These factors are reported(More)
Code clone analysis is valuable because it can reveal reuse behaviours efficiently from software repositories. Recently, some code reuse analyses using clone genealogies and code clones over multiple projects were conducted. However, most of the conventional analyses do not consider the developers' individual difference to reuse behaviors. In this paper, we(More)
In the software industry and OSS projects, it is said that source code reuse could improve productivity and reliability of software development, and reduce development time. On the other hand, source code reuse requires professional skills to developers. Ad-hoc reuse might introduce some maintenance problems. The source code reuse analysis for software(More)
In the software industry and OSS projects, it is said that code reuse could improve productivity and reliability of software development, and reduce development time. In many software development organizations, reuse of existing libraries and source code is recommended. Developers in such organizations are required to implement reusable source code and(More)
We report a case of longstanding asymptomatic direct carotid-cavernous fistula (CCF) which caused fatal subarachnoid hemorrhage (SAH). A 91-year-old female with no history of previous head trauma and optic symptoms presented acute subarachnoid hemorrhage. Angiography revealed a left direct carotid-cavernous fistula draining only into the contralateral(More)
It is well-known that idiopathic neuralgias of the trigeminal and glossopharyngeal nerves are caused by vascular compression at the root entry zone of the cranial nerves. Because they are functional diseases, initial treatment is medical, especially with carbamazepine. However, if medical therapy fails to adequately manage the pain, microvascular(More)
