The apparent viscosity of baker's yeast suspensions was employed to control the cell concentration of the mixing of baker's yeast and distilled water. The apparent viscosity of baker's yeast was found to be a function of cell concentration and independent of the flow rate through the rotational...
近日,美国斯坦福大学Onn Brandman在Cell发表文章Cellular Control of Viscosity Counters Changes in Temperature and Energy Availability,指出细胞质也有一套机制可以使其在不同温度下维持黏性恒定。这种胞质黏性的调节是细胞应对不同温度或急性环境刺激,维持稳态的重要手段。 为了研究细胞质内环境的稳态调节机制,作者建立了...
Viscosity The important factor for cell suspension cultured in stirred vessels or when cells are dissociated after trypsinization [52] Table 2. The cell cultures environment [71, 73, 75, 79, 80]. In the 1920s, composition of salt solutions was formulated specifically for cell cultures, for ex...
Cells respond to physical stimuli, such as stiffness1, fluid shear stress2and hydraulic pressure3,4. Extracellular fluid viscosity is a key physical cue that varies under physiological and pathological conditions, such as cancer5. However, its influence on cancer biology and the mechanism by which ...

which is valid where the viscosity of the protein condensed phase (ηint) is much higher than the viscosity of the protein dilute phase (ηext). For instance, viscosity of the Bik1 droplet phase has been reported previously as \(\eta _{{\mathrm{int}}} \approx 18.2\left( {Pa \cdot ...
The relative roles of two fundamental determinants of red cell deformability, namely cell size and cellular viscosity, in affecting red cell passage through narrow channels have been assessed by determining the filterability of red cells subjected to osmotic variations. Suspensions of red cells (10(6...
A special type of phase transition where increasing (jamming) or decreasing (unjamming) the packing of particles in a granular material leads to a macroscopic viscosity change. This theoretical framework has been used to describe the packing of cells in a biological tissue. Wetting The spreading ...
