13. Cell sorting is analogous to phase ordering in fluids
Morphogenetic processes, like sorting or spreading of tissues, characterize early embryonic development. An analogy between viscoelastic fluids and certain properties of embryonic tissues helps interpret these phenomena. The values of tissue-specific surface tensions are consistent with the equilibrium configurations that the Differential Adhesion Hypothesis

14. Measurement of fluid viscosity at microliter volumes using quartz impedance analysis
The purpose of this work was to measure viscosity of fluids at low microliter volumes by means of quartz crystal impedance analysis. To achieve this, a novel setup was designed that allowed for measurement of viscosity at volumes of 8 to 10 μL. The technique was based on the principle of electromechanical coupling of piezoelectric quartz crystals. The arran

15. An Engineering Study of the Peristaltic Drive of Axonal Flow*
By determination of the rheological flow curve of minute quantities of axoplasm drawn into a microcapillary tube connected to a high vacuum, extruded axoplasm was shown to behave as a pseudoplastic fluid with a viscosity of 106-times that of water and without significant signs of time-dependent thixotropic or viscoelastic properties. A theoretical analysis o

16. Tree shrew lavatories: a novel nitrogen sequestration strategy in a tropical pitcher plant
Nepenthes pitcher plants are typically carnivorous, producing pitchers with varying combinations of epicuticular wax crystals, viscoelastic fluids and slippery peristomes to trap arthropod prey, especially ants. However, ant densities are low in tropical montane habitats, thereby limiting the potential benefits of the carnivorous syndrome. Nepenthes lowii, a

17. Characterization of exosome-like vesicles released from human tracheobronchial ciliated epithelium: a possible role in innate defense
Airway mucus forms the structural basis of the local innate immune defense mechanism. It is an integrated, active, viscoelastic gel matrix evolved to protect the exposed lung from physical, chemical, and pathological erosion. Exosomes are biologically active vesicles secreted by different cell types including epithelial, hematopoietic, and some tumor cells.
