  • vivo
  • In this study, an in vivo stable isotope-mass spectrometric technique was used to measure the turnover, or dynamicity, of MTs in brains of living animals. (jneurosci.org)
  • Since radiolabeled isotopes can be substituted in biomolecule monomers without any changes to the chemical structure, they are readily incorporated in vivo . (thermofisher.com)
  • nucleus
  • The nucleus of deuterium is called a deuteron , contains ONE proton and (typically for the deuterium isotope) ONE neutron, whereas the far more common hydrogen nucleus contains no neutron. (answers.com)
  • fact
  • Such mutualisms are considered evolutionarily stable and, in fact, are often characterized by a high level of phylogenetic congruency among partners (Sauer et al. (springer.com)
  • possible
  • This appears to be possible because P . gracilis relies less on host-derived food resources than does the mutualist, as shown by behavioral and stable isotope studies. (springer.com)
  • vary
  • The times that the decay event takes to occur vary as the isotope, and are called half-lives. (answers.com)
