Surface Structure of Isolated Neurons
Freehand, isolated neuronal perikarya from the hypoglossal nucleus of the rabbit have been examined with light-and electron-microscopy (transmission and scanning). The surface of the cell bodies was largely covered with spherical particles which were 0.5-2 micro in diameter. Transmission electron microscopy proved that the spherical particles were synaptic nerve terminals. Crush of the hypoglos...
متن کاملEffects of dalteparin on structure of hippocampal neurons of rats in chronic stress
Introduction: Stress is defined as any environmental change that disturbs the maintenance of brain homeostasis. Stress leads to production of pro-inflammatory cytokines that provoke neurodegenerative disorders. In the present study, we investigated the effects of dalteparin on hippocampal neuronal death induced by chronic stress in rats. Methods: the study was carried out on 60 adult male wista...
متن کاملEarthquake Analysis of Base Isolated Structures Including Soil-Structure Interaction
A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...
