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.
Neuron-glia communication by extrasynaptic transmission
Syková, Eva
Dynamic changes in ECS ionic composition, volume and geometry accompany neuronal activity, neuronal loss, glial development and proliferation, aging, CNS injury, anoxia/ischemia, spreading depression, tumors, inflammation dyemyelination and many other brain pathological states.
Biocompatible polymer hydrogels usable for nervous tissue regeneration
Lesný, Petr ; DeCroos, Jane ; Přádný, Martin ; Vacík, Jiří ; Syková, Eva
PHPMA hydrogel matrices have the ability to induce tissue formation within them and therefore support the regeneration of nervous tissue.
Diffusion and MRS in a rat cortex after traumatic injury
Voříšek, Ivan ; Herynek, V. ; Burian, M. ; Hájek, M. ; Niclay, K. ; Syková, Eva
An increase in diffusion barriers, manifestes by a decrease of both ADCTMA and ADCW, occurs throughout the entire cortex of the wounded hemisphere. These changes are related to astrogliosis and to an accumulation of extracellular matrix molecules without significant changes in ECS volume.
Diffusion of PHPMA polymers in brain extracellular space
Vargová, Lýdia ; Kubinová, Šárka ; Tao, L. ; Ulbrich, Karel ; Šubr, Vladimír ; Nicholson, C. ; Syková, Eva
The movement of bulky PHPMA polymers through ECS is limited in contrast to linear PHPMA macromolecules which have the same ability to explore ECS as small molecules.
