• protein
  • To confirm that the homologous recombination event resulted in a allele for protein expression, myofibrils were purified from tibialis anterior, which in +/+ mice expresses high levels of MyHC-IId/x and IIb. (nih.gov)

  • Our results indicate that by incorporating various myofibril inhomogeneities such as skew and domain effect in the theoretical model, a variety of observations in single fiber diffraction under different experimental conditions can be reproduced in the simulation. (osapublishing.org)
  • length
  • Based on the framework of sliding-filament theory and on the cross-bridges dynamics, a mathematical model for the simulation of the force response and length change of individual myofibril is presented. (springer.com)
  • development
  • A study of the developing leg muscle in a 12-day chick embryo using electron microscopy proposes a mechanism for the development of myofibrils. (wikipedia.org)
  • A model experiment is described which demonstrates the importance of the rate of tension development in causing myofibril splitting. (biologists.org)
  • presence
  • Myofibrils which lengthen by several per cent in the presence of ATP and magnesium ions were prepared by teasing indirect flight muscle of Drosophila in solutions containing ethylenediaminetetraacetate. (rupress.org)
