Viscoelastic Properties of the Cell Nucleus

Biochemical and Biophysical Research Communications, 2000
Mechanical factors play an important role in the regulation of cell physiology. One pathway by which mechanical stress may influence gene expression is through a direct physical connection from the extracellular matrix across the plasma membrane and to the nucleus.

Viscoelastic properties of cumulus oöphorus

Biorheology, 1976
An experimental technique suitable for the determination of the rheological properties of minute, biological viscoelastic solid specimens is presented. This technique is employed to ascertain the viscoelastic properties of the rabbit cumulus oöphorus. The experimental results when analyzed using the finite theory of elasticity reveal that the cumulus ...

VISCOELASTIC PROPERTIES OF NETWORKS

International Journal of Modern Physics C, 2009
A network was characterized by its viscoelastic properties. The viscoelastic property indicates the deformations or changes in the shape and in the internal structure during the evolution of a network. The change in the direction of motion was taken as elastic deformation and the change in the vertical direction as viscous deformation.

Viscoelastic Properties of Microtubule Networks

Macromolecules, 2007
Microtubules are filamentous protein biopolymers found in eukaryotic cells. They form networks that guide active intracellular transport and support the overall cell structure. Microtubules are very rigid polymers, with persistence lengths as large as a millimeter.

Attenuation Properties of Viscoelastic Material

pure and applied geophysics, 1989
The attenuation properties of eight Theological models have been studied theoretically. The expressions for Q have been obtained by using dissipated and stored energies and/or complex modulus for each model. The dependence of Q on frequency has been demonstrated.

MR imaging of viscoelastic properties

Journal of Magnetic Resonance Imaging, 1995
AbstractMechanical waves in magnetic resonance imaging, which have been suggested for possible clinical applications, were analyzed with regard to imaging of the viscoelastic properties of large objects. The method is based on the Larmor frequency modulation caused by the application of mechanical waves.

The viscoelastic properties of actin solutions

Archives of Biochemistry and Biophysics, 1982
Abstract The viscoelastic properties in actin solutions were investigated by measuring their elastic modulus and viscous modulus using a rheometer. The polymerization/gelation process of actin solutions was accompanied by an increase of both parameters, indicating the formation of a protein network. High shear rotational motion destroyed this network

Meniscal tears often lead to degenerative arthritis, attributed primarily to the changes in the magnitude and pattern of stress distribution in the knee. While meniscal replacement traditionally involves implantation of allografts, problems related to availability, size matching, and cost limit their use. In this regard, there are significant potential

Viscoelastic Properties of Ice

Journal of Applied Physics, 1956
An apparatus has been constructed for the study of deformation under tension of single and polycrystalline ice. Deformations down to 10−5 cm could be measured. Deformation of single and polycrystals was investigated as a function of time, stress, and temperature.

Viscoelastic Properties of Butter

Journal of Food Science, 1995
ABSTRACT Viscoelastic properties were studied on butters prepared from fractionated high‐melting triglyceride (HMT) and anhydrous milk fat (AMF). The elastic moduli (G′), the viscous moduli (G″) and the complex viscosities (η*) were determined as functions of angular frequency (ω).
