  • In her early research in systematic cytology Goldschmidt was especially interested in adaptations to harsh conditions, such as extreme salinity.

    Elisabeth Goldschmidt.

  • The study of cells was transformed from descriptive cytology into molecular cell biology (Alberts et al. 1983; Alberts et al. 2002; Bechtel 2006).

    Molecular Biology

  • That the linked amino acid components alone are insufficient causally, even if they are sufficient constitutionally, allows for a more explicit appreciation of the significance of temporality, especially because the relations of interest concern molecular biological phenomena (as opposed to appeals to higher levels of organization from cytology or anatomy).

  • Examples of fields are genetics, biochemistry and cytology.

    The Unity of Science

  • And there are a number of studies out there right now trying to compare if chest x-rays provide as much information as these CT scans, bronchoscopy, sputum cytology, and even little tests involving needle biopsies to fin out if we can locate these cancers early and extend those patients 'lives.
