Ultrastructural morphological alterations during hyperoxia exposure in relation to glutathione peroxidase activity and free radicals productions in the mitochondria of the cortical brain

Int. j. morphol; 36 (4), 2018
Exposure to normobaric hyperoxia (NH) is known to increase the production of reactive oxygen species (ROS) by mitochondria. The present study was designed to examine mitochondrial ultrastructure morphological changes in the cortical brainin relation to glutathione peroxidase (GPX) activity and free radic...

Impact of dexmedetomidine on amino acid contents and the cerebral ultrastructure of rats with cerebral ischemia-reperfusion injury

Acta cir. bras; 32 (6), 2017
Abstract Purpose: To investigate the effects of dexmedetomidine (DEX) on amino acid contents and the cerebral ultrastructure of rats with cerebral ischemia-reperfusion injury (I/R). Methods: Thirty-six, male, Wistar rats were randomly divided into three groups: the sham operation group (group C), the i...

Poda selectiva de las proyecciones comisurales del colículo superior de la rata durante el desarrollo posnatal
Selective pruning of commisural projections in the superior colliculus of the rat during posnatal development

Rev. chil. anat; 12 (4), 1994
En el presente trabajo he estudiado los cambios que ocurren en proyecciones intercoliculares rata durante el desarrollo posnatal de la rata. El uso de la carbocianina DiI ha permitido marcar los axones comisurales del colículo superior. Durante el período postnatal temprano (P-1 a P-5), se observan pro...
