Development of right-left asymmetry in the chick embryo
Buckiová, Daniela ; Kofroňová, Olga ; Jelínek, R.
Using SEM we have studied the ventral surface of the chick node. In contrast to mouse, we have found neither the pit nor the cilia.
Morphology and distribution of nadph-diaphorase-positive neurons in the auditory cortex of the rat
Nwabueze-Ogbo, Fidel Chijoke ; Druga, R. ; Syka, Josef
Our results indicate the preferred localization of the NADPH-d/NOS positive neurons in the infragranular layers, which are sources of the majority of corticofugal neurons projecting to the subcortical structures.
Nucleoli of naked megakaryocytic nuclei
Janoutová, J. ; Likovský, Zbyněk
The differentiation and maturation of megakaryocytes is characterized by endomitotic divisions which result in the formation of large polyploid cells the cytoplasm of which is segregated as thrombocytes. The present study was undertaken to provide more information on the incidence of nucleoli in naked magakaryocytic nuclei representing terminal stages of the megakaryocytic development after the loss of the cytoplasm transformed to thrombocytes.
Abnormal skeletogenesis occurs in the Splotch (Sp2H) Mutant
Lišková, J. ; Růžičková, Kateřina ; Buckiová, Daniela
Homozygous Splotch embryos (days 16.5-18.5 of gestation)displayed severe rib and neural arches abnormalities. (100% penetrance).
Up-regulation of delayed outwardly rectifying potassium currents in reactive astrocytes after certical stab wound
Anděrová, Miroslava ; Neprašová, H. ; Petřík, D. ; Chvátal, Alexandr ; Syková, Eva
Hypertrophied astrocytes in the close vicinity of the stab wound are characterized by an up-regulation of delayed outwardly rectifying K+ currents and increased K+ accumulation in the vicinity of the astrocyte membrane.
Extracellular space size and geometry in the brain of APP23 mice representing a model of Alzheimer´s disease
Mazel, Tomáš ; Antonova, Tatiana ; Meyer-Luhmann, M. ; Staufenbiel, M. ; Jucker, M. ; Syková, Eva
The decrease in ECS size observed during aging might contribute to increased extracellular amyloid concentration and deposition in APP23 mice.
Alterated diffusion parameters in the brain with kaolin-induced hydrocephalus
Fiala, Jindřich ; Antonova, Tatiana ; Voříšek, Ivan ; Syková, Eva
Compression of the ECS in the cerebral cortex following induction of hydrocephalus, slows down the diffusion of neuroactive substances in hydrocephalic tissue.
Extracellular space volume fraction and geometry in human cortex and glial tumors
Homola, Aleš ; Vargová, Lýdia ; Zámečník, J. ; Tichý, M. ; Beneš, V. ; Syková, Eva
Ecs diffusion parameters in human temporal cortex similar to those previously determined in rat cortex. Volume fraction ? and tortuosity ? are increased in astrocytic gliomas and the higher the glioma´s WHO grade the greater the ECS volume and tortuosity increase. Migration and invasiveness correlate with an increase in ECS volume.
