NADPH-d - positive neurons in the auditory cortex of young and very old rats
Nwabueze-Ogbo, Fidel Chijoke; Druga, R.; Syka, Josef
2001 - anglický
In young and very old animals stained neurons were localized in layers II-VI and in the subcortical white matter. A significantly higher packing density of labeled supragranular layers. In very old animals the thickness of the auditory cortex and the neuronal density was reduced when compared to the young.

Representation of communication sounds in the inferior colliculus of the guinea pig
Šuta, Daniel; Kvašňák, Eugen; Popelář, Jiří; Syka, Josef
2001 - anglický
The spectrotemporal discharge patterns of the neuronal population were clearly related to the spectrotemporal acoustic patterns of vocalization sounds.This study provides evidence for encoding of the spoctrotemporal acoustic pattern of vocalization sounds in a spcific and distributed way by the firing patterns of a population of IC units.

Extracellular space volume fraction and geometry in human cortex and glial tumors
Homola, Aleš; Vargová, Lýdia; Zámečník, J.; Tichý, M.; Beneš, V.; Syková, Eva
2001 - anglický
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. Klíčová slova: glial tumors Plné texty jsou dostupné na jednotlivých ústavech Akademie věd ČR.

Peripheral and central changes of the auditory system in the elderly
Mazelová, Jana; Popelář, Jiří; Valvoda, Jaroslav; Syka, Josef
2001 - anglický
We compared the hearing abilities of 15 elderly subjects with a group of 15 young normal hearing. The results of this study support the opinion of many other suthors that the problems of aged people do not result ohly from elevated audiometric thresholds, but also from processes of central oring.

Transport of ribosomal RNA within the nucleolus
Staněk, David; Koberna, Karel; Pliss, Artem; Čtrnáctá, Vlasta; Malínský, Jan; Mašata, Martin; Večeřová, Jaromíra; Raška, Ivan
2000 - anglický
In the present study, we have explored the fact that incorporation of BrU into prerRNA did not interfere with pre-rRNA processing (11) and we have investigated the transport of non - isotopically labeled RNA within the nucleolus by means of transmissiion electron microscopy and confocal laser scanning microscopy.Within 20 minutes, BrU - labeled nucleolar RNA moved from the transcription sites in nucleolar DFC to GC. Double localization of bromouridine labeled RNA and fibrillarin revealed that only a ppart of the fibrillarin rich domains were transcriptionally active.

Interactions between PML nuclear bodies and nuclear DNA helicase II
Fuchsová, Beáta; Novák, P.; Kafková, J.; Hozák, Pavel
2000 - anglický
Our findings suggest that NDH II recruitment to PML NBs might be important for the role of this nuclear domain in transcriptional regulation and are consistent with the model that PML protein functions as a transcription factor. Plné texty jsou dostupné na jednotlivých ústavech Akademie věd ČR.

Morphology and distribution of nadph-diaphorase positive neurons in the auditory cortex of the rat
Nwabueze-Ogbo, Fidel Chijoke; Druga, R.; Syka, Josef
2000 - anglický
Our results indicate the preferred lacalization 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. Plné texty jsou dostupné na jednotlivých ústavech Akademie věd ČR.

Spliceosomal Assembly on Precursor mRNA Takes Place in the Nuclear Speckles
Melčák, Ivo; Cermanová, Štěpánka; Raška, Ivan
2000 - anglický
Nuclear speckles (speckles), enriched in splicing factors, form a distict nuclear compartment within the interchromatin space. It has been schown to serve vicinal active genes as a reservoir of splicing factors.We show that (pre-)spliceosomal assemblyy on pre-mRNA is associated with the speckles in HeLa cells.
