  • Diffusion
  • Our measurements of single-particle trajectories in cytoplasm and their random-walk interpretations elucidate two of these mechanisms: molecular diffusion in crowded environments and cytoskeletal transport along microtubules. (nih.gov)
  • The more complex simulations performed surprisingly well when asked to predict molecular behaviors, such as diffusion and stability, in the E. coli cytoplasm. (biomedicalcomputationreview.org)
  • viruses
  • As with most RNA viruses, this class replicates in the "Core" capsid that is in cytoplasm, not having to use the host replication polymerases to as much a degree as DNA viruses. (wikipedia.org)
  • These can be divided into two groups, both of which reproduce in the cytoplasm: Viruses with polycistronic mRNA where the genome RNA forms the mRNA and is translated into a polyprotein product that is subsequently cleaved to form the mature proteins. (wikipedia.org)
  • proteins
  • Sera from 105 HIV-infected patients were tested for anti-neutrophil cytoplasm antibodies (ANCA) by indirect immunofluorescence (IIF), by specific ELISAs using target proteins of ANCA and by a neutrophil cytoplasm extract ELISA. (springer.com)
  • A computational box of 1008 proteins is still a far stretch from the complex E. coli cytoplasm, says Allen Minton, PhD , a pioneer in the study of crowding effects and researcher of physical biochemistry at the National Institutes of Health. (biomedicalcomputationreview.org)
  • The cytoplasm also contains proteins that control the replication of DNA in bacterial cells. (reference.com)
  • A solid glass cytoplasm would freeze subcellular structures in place, preventing damage, while allowing the transmission of very small proteins and metabolites, helping to kickstart growth upon the cell's revival from dormancy. (wikipedia.org)
  • cells
  • Cytoplasm can be found in both plant and animal cells. (sophia.org)
  • It is equally plausible that the exceptional male fertility is the result of occasional transfer of normal cytoplasm through the male germ cells of maintainer parents. (genetics.org)
  • According to Hartnell College, cytoplasm is a common feature of all cells regardless of the type of organism the cells come from. (reference.com)
  • By using fluorescent probes and microscopy, Cheng and Ferrell show that in frog eggs (which are very large cells), waves of apoptotic signals can be seen passing through the egg cytoplasm. (sciencemag.org)
  • molecules
  • While small signaling molecules like calcium ions are able to diffuse with ease, larger molecules and subcellular structures often require aid in moving through the cytoplasm. (wikipedia.org)
  • It is thought that the component molecules and structures of the cytoplasm behave at times like a disordered colloidal solution (sol) and at other times like an integrated network, forming a solid mass (gel). (wikipedia.org)
  • qualitative
  • In addition to providing a dramatic, qualitative description of the crowded cytoplasm, this first atomically detailed computational model of E. coli innards is also a tool for quantitative predictions of molecular conduct within the cell. (biomedicalcomputationreview.org)
  • liquid
  • Recently it has been proposed that the cytoplasm behaves like a glass-forming liquid approaching the glass transition. (wikipedia.org)
  • Sonneborn demonstrated during his research on Paramecium that the structure of the cortex was not dependent on genes, or the liquid cytoplasm, but in the cortical structure of the surface of the ciliates. (wikipedia.org)
  • found
  • The team, led by Ming Guo, the Brit and Alex d'Arbeloff Career Development Assistant Professor in MIT's Department of Mechanical Engineering, found that an organelle feels a certain resistance in cytoplasm, depending on that organelle's size and the speed at which it moves through a cell. (eurekalert.org)
  • Exoerythrocytic schizogony occurs in the mononuclear phagocyte system A blue, pale blue or white globule, frequently refractory, can be found in the cytoplasm. (wikipedia.org)
  • allow
  • The apoptotic control network includes several positive feedback loops that may allow apoptosis to spread through the cytoplasm in self-regenerating trigger waves. (sciencemag.org)
