An ultrastructural study of human pineal glands obtained at autopsy from 7 patients older than 70 years was conducted in order to clarify the functional anatomy of the pineal in the aged. By light microscopy, the pineal glands from aged patients were parenchymatous and almost indistinguishable from those of younger controls. Electron microscopy of the(More)
Japanese common newts (Cynops pyrrhogaster) have high ability to regenerate their injured organs including neural tissues, for example, the neural retina belonging to central nervous system. We attempted to clarify the molecular mechanism underlying the formation of a neural network during newt retina regeneration, and focused on the microtubule dynamics(More)
Programs executing on a private-memory parallel system exchange data by explicitly sending and receiving messages. Two communication styles have been identified for such systems: memory communication (each message exchanged between two processors is buffered in memory, e.g. as in message passing) and systolic communication (each word of a message is(More)
— In this paper, we presented a design for an automated cell supply system that can be used with complex microfluidic applications requiring single cell loading such as the current nuclear transplantation method. The aim of the system is to automatically transfer mammalian donor (∼15µm) or egg (∼100µm) cells one by one from a container to a PDMS(More)
