- Hypoxia/hypoglycemia preconditioning prevents the loss of functional electrical activity in organotypic slice culturesJerome Badaut
Neurosurgery Research Group, Centre Hospitalier Universitaire Vaudois CHUV, Pavillon 3 Beaumont, 1011 Lausanne, Switzerland
Brain Res 1051:117-22. 2005..The major interest and advantage of this system over both the acute slice preparation and primary cell cultures is the ability to simultaneously measure the delayed neuronal damage and neuronal function...
- Time course of aquaporin expression after transient focal cerebral ischemia in miceMarlise de Castro Ribeiro
