Transport of ribosomal RNA within the nucleolus
Staněk, David ; Koberna, Karel ; Pliss, Artem ; Čtrnáctá, Vlasta ; Malínský, Jan ; Mašata, Martin ; Večeřová, Jaromíra ; Raška, Ivan
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.
Charge ordering and phase transitions in perovskite manganites: correlation with CMR properties
Hervieu, M. ; Martin, C. ; Van Tendeloo, B. ; Mercey, B. ; Maignan, A. ; Jirák, Zdeněk ; Raveau, B.
Different parameters playing a role in the charge ordering are highlighted and analysed. The problem of phase segreg ation is discussed.
