The process of β-amyloid accumulation in cerebral vessels is presented. Cerebral amyloid angiopathy (CAA) was confirmed during an autopsy. It was diagnosed according to the Boston criteria. Cerebral amyloid angiopathy can involve all kinds of cerebral vessels (cortical and leptomeningeal arterioles, capillaries and veins). The development of CAA is a(More)
Bystander CPR in first minutes after cardiac arrest appears to be a crucial component of the chain of survival.

Three calcium-binding proteins (CaBPs), calbindin D28k, calretinin and parvalbumin, were immunohistochemically examined in the cerebellum of ten-day-old rat pups of ethanol-treated dams. Dams were treated with ethanol during pregnancy and/or lactation. In the cerebellar cortex of the pups from control groups, Purkinje cells with their processes and Golgi(More)
A bstract-The design and implementation of a microprocessor-based system to control the interaction forces between a five-axis articulated robot and a workpiece is described.
