Description:
The objective of the current study is to present data on the splitting of skeletal muscle fibers in C57BL/6NCrl mice. Skeletal muscles (m. rectus femoris (m. quadriceps femoris)) from 500 (250 ♀ and 250 ♂) C57BL/6NCrl mice in the 16th week of life were sampled during autopsy and afterwards standardly histologically processed. Results show spontaneous skeletal muscle fiber splitting which is followed by skeletal muscle fiber regeneration. One solitary skeletal muscle fiber is split, or is in contact with few localized splitting skeletal muscle fibers. Part of the split skeletal muscular fiber is phagocytosed, but the remaining skeletal muscular fiber splits are merged into one regenerating skeletal muscle fiber. Nuclei move from the periphery to the regenerating skeletal muscle fiber center during this process. No differences were observed between female and male mice and the morphometry results document <1 % skeletal muscle fiber splitting. If skeletal muscular fibers splitting occurs 5 %> of all skeletal muscular fibers, it is suggested to describe and calculate this in the final histopathological report.

Description:
V referátu přinášíme shrnutí některých našich výsledků z oblasti studia růstu atomárních struktur kombinací experimentálního a teoretického přístupu. Řádkovací tunelová mikroskopie (STM) nám poskytuje atomárně rozlišenou informaci v reálném prostoru, která umožňuje navržení modelu růstu, jenž je dále rozvíjen pomocí kinetických Monte Carlo (KMC) simulací., We briefly summarize our results concerning the field of growth of atomic structures, using a combination of experimental and theoretical approaches. Scanning tunnelling microscopy (STM) provides atomically resolved information in real space allowing us to propose growth models, which can be further developed using kinetic Monte Carlo (KMC) simulations., Pavel Kocán, Pavel Sobotík, Ivan Ošťádal., and Obsahuje bibliografii
