Linear and nonlinear rheology of living cells
Nettethere. For example, sections have been included on controlled/living free radical polymerization, and sections on metathesis type polymerization and metallocene catalysts were expanded. The book was also expanded to include discussions of thermodynamics of elasticity, thermodynamics of polymeric solutions, and rheology and viscoelasticity. NettetMeasuring rheological properties of cells in monolayers enables quantifying average cell properties in single experimental runs despite large cell-to-cell variations. Here, we describe how to modify a commercial rotational rheometer to accomplish the …more

Nettet7. mar. 2016 · Here, v is the vector velocity of the cells inside the tumor (a liquid); is the 'homeorhetic' or mechanical pressure defined as the isotropic force per unit area exerted by cells normally on any arbitrary surface within the steadily-growing tumor, i.e. , while are the Darcy permeability, and the effective cell viscosity that reflects the complex … NettetFigure 1 MAP plotted as function of Hct for the study population of individuals described in Table 1. Notes: The association MAP/Hct is positive and significant (P=0.04, r=0.10) for women (n=442) and negative but not significant (r=−0.05) for men (n=174). This association becomes negative but not significant for women when individuals with …

NettetIn this study, we examine the effects of injectable liberase (a blend of collagenase and thermolysin enzymes) treatments on the linear and nonlinear rheology of allograft 4T1 mouse mammary tumors. We perform two sets of in vivo mouse studies, in which either one or multiple treatment injections occur before the tumors are harvested for …
