“…The fibre direction response observed was less stiff than the responses observed by both Morrow et al and Nie et al (Nie et al, 2011, Morrow et al, 2010, but close to the findings of Calvo et al (Calvo et al, 2010), see Figure 14 and Table 4. Calvo et al used a slightly lower strain rate of 0.025%/s, see Figure 4 and Table 4, and this may partially account for their lower stiffness results, as it is known that skeletal muscle is viscoelastic even at very low strain rates (Van Loocke et al, 2008).…”

“…Morrow et al observed stiffer fibre directional responses than was observed in this paper (Morrow et al, 2010), and this may be largely attributed to the different experimental protocol used. More importantly, Morrow et al, 2010 froze their samples within an hour of the animal sacrifice, but no effort was made to discuss the thawing process they used. Although it has been found that a freeze thaw cycle does not affect the post rigor response of muscle tissue (Van Ee et al, 2000), the thawing process remains an important part of their experiments as it is likely to have allowed rigor mortis to set in and make the tissue much stiffer (the rigor mortis characterisation investigation performed on freshly harvested porcine tissue (Van Loocke, et al,.…”

“…A Poisson's ratio of 0.5 was observed for the strain in both transverse directions (T and T' in Figure 2) arising from the compressive load applied in the fibre or longitudinal (L) direction, indicating isotropic and incompressible behaviour for this mode of loading. However when compressive load was applied in a transverse direction (T), the resulting expansion in the fibre (L) and the remaining transverse (T') directions was characterized by Poisson's ratios of 0.36 and 0.65 respectively, see The tensile response of passive skeletal muscle is also nonlinear and viscoelastic (Nie et al, 2011, Calvo et al, 2010, Morrow et al, 2010, Martins et al, 1998, Meyers, 1994, Grieve and Armstrong, 1988, Yamada, 1970, Lissner et al, 1960, Martins et al, 2006. Figures 1a shows the fibre direction tensile stress-stretch response observed by different authors, and some of the variability in the data may be a result of viscoelasticity.…”

The anisotropic mechanical behaviour of passive skeletal muscle tissue subjected to large tensile strain, Journal of the Mechanical Behavior of Biomedical Materials, http://dx.doi.org/10. 1016/j.jmbbm.2012.09.001 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form.

AbstractThe passive mechanical properties of muscle tissue are important for many biomechanics applications. However, significant gaps remain in our understanding of the three-dimensional tensile response of passive skeletal muscle tissue to applied loading. In particular, the nature of the anisotropy remains unclear and the response to loading at intermediate fibre directions and the Poisson's ratios in tension have not been reported. Accordingly, tensile tests were performed along and perpendicular to the muscle fibre direction as well as at 30, 45 and 60 degrees to the muscle fibre direction in samples of Longissimus dorsi muscle taken from freshly slaughtered pigs. Strain was measured using an optical non-contact method. The results show the transverse or cross fibre (TT') direction is broadly linear and is the stiffest (77kPa stress at a stretch of 1.1), but that failure occurs at low stretches (approximately λ = 1.15). In contrast the longitudinal or fibre direction (L) is nonlinear and much less stiff (10kPa stress at a stretch of 1.1) but failure occurs at higher stretches (approximately λ = 1.65). An almost sinusoidal variation in stress response was observed at intermediate angles. The following Poisson's ratios were measured: Ѵ LT = Ѵ LT' = 0.47, Ѵ TT' = 0.28 and Ѵ TL = 0.74. These observations have not been previously reported and they contribute significantly to our understanding of the three dimensional deformation response of skeletal muscle tissue.

“…Further work to characterise all the material properties in the human leg and match them to a material model in the same manner as undertaken by [23] would be of considerable benefit to future studies that are similar to the present one. Additionally, this study has assumed that the material properties are isotropic, whereas in reality they are highly anisotropic [30]. In future studies it will be interesting to incorporate anisotropic properties and assess its influence upon wave propagation and MRE measurements.…”

Purpose: To develop finite element analysis (FEA) of magnetic resonance elastography (MRE) in the human thigh and investigate inter-individual variability of measurement of muscle mechanical properties. Methods: Segmentation was performed on MRI datasets of the human thigh from 5 individuals and FEA models consisting of 12 muscles and surrounding tissue created. The same material properties were applied to each tissue type and a previously developed transient FEA method of simulating MRE using Abaqus was performed at 4 frequencies. Synthetic noise was applied to the simulated data at various levels before inversion was performed using the Elastography Software Pipeline. Maps of material properties were created and visually assessed to determine key features. The coefficient of variation (CoV) was used to assess the variability of measurements in each individual muscle and in the groups of muscles across the subjects.

Hollis) Preprint submitted to Magnetic Resonance Imaging June 27, 2017 A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTmeasurements for the set of muscles were ranked in size order and compared with the expected ranking.Results: At noise levels of 2% the CoV in measurements of |G * | ranged from 5.3 to 21.9% and from 7.1 to 36.1% for measurements of φ in the individual muscles. A positive correlation (R 2 value 0.80) was attained when the expected and measured |G * | ranking were compared, whilst a negative correlation (R 2 value 0.43) was found for φ. Conclusions:Created elastograms demonstrated good definition of muscle structure and were robust to noise. Variability of measurements across the 5 subjects was dramatically lower for |G * | than it was for φ. This large variability in φ measurements was attributed to artefacts.

Tuning Molecular Adhesion via Material Anisotropy

Cell adhesion with extracellular matrix depends on the collective behaviors of a large number of receptor-ligand bonds at the compliant cell-matrix interface. While most biological tissues and structures, including cells and extracellular matrices, exhibit strongly anisotropic material properties, existing studies on molecular adhesion via receptor-ligand bonds have been largely limited to isotropic materials. Here the effects of transverse isotropy, a common form of material anisotropy in biological systems, in modulating the adhesion behavior of a cluster of receptor-ligand bonds are investigated. The results provide a theoretical basis to understand cell adhesion on anisotropic extracellular matrices and to explore the possibility of controlling cell adhesion via anisotropy design in material properties. The combined analysis and simulations show that the orientation of material anisotropy strongly affects the apparent softness felt by the adhesive bonds, thereby altering their ensemble lifetime by several orders of magnitude. An implication of this study is that distinct cellular behaviors can be achieved through remodeling of material anisotropy in either extracellular matrix or cytoskeleton. Comparison between different loading conditions, together with the effects of material anisotropy, yields a rich array of out-of-equilibrium behaviors in the molecular interaction between reactant-bearing soft surfaces, with important implications on the mechanosensitivity of cells.
