Excitatory amino acids exert a depolarizing action on central nervous system cells through an increase in cationic conductances. Non-NMDA receptors have been considered to be selectively permeable to Na+ and K+, while Ca2+ influx has been thought to occur through the NMDA receptor subtype. Recently, however, the expression of cloned non-NMDA receptor(More)
Glutamic acid is an important excitatory neurotransmitter in the mammalian CNS. It has been established that synaptic transmission is mediated mostly by the ionotropic glutamate receptors AMPA and NMDA, with fast and slow kinetics, respectively. The recent demonstration in hippocampal neurones of a class of glutamate receptors that are activated by kainate(More)
The study of regulated vesicle exocytosis, which underlies neurotransmitter and neuropeptide release, has benefited from a convergence of several independent approaches. These include the use of genetically tractable organisms and model preparations that allow a direct characterization of presynaptic ionic currents. Aiming for a comprehensive analysis of(More)
Horizontal osteotomy allows the surgeon to safely down-fracture the maxilla for wide exposure of the central skull base. This surgical approach is easily extended posteriorly in the midline to include the clivus and the arch of C1, providing 8 cm of horizontal anterior exposure and 5 cm of posterior. Wide operative exposure and a low rate of complications(More)
ACKNOWLEDGEMENTS The Channel Islands Golden Eagle Translocation Project has been successful over the past five years due to the efforts of many people from several different agencies and groups many of whom have made the preservation and recovery of the island fox a priority in their personal and professional lives. These people deserve our thanks and(More)
