Mechanical response of human female breast skin under uniaxial stretching

Mechanical response of pig skin under dynamic tensile loading

Uniaxial tensile experiments were performed on pig skin to investigate the tensile stressestrain response at both quasi-static and dynamic rates of deformation. A Kolsky tension bar, also called a split Hopkinson tension bar (SHTB), was modified to conduct the dynamic experiments. Semiconductor strain gages were used to measure the low levels of the transmitted signal from pig skin. A pulse sha...

Ratchetting of porcine skin under uniaxial cyclic loading.

Skin soft tissue (e.g., porcine skin) was tested in vitro under uniaxial cyclic loading, and its biomechanical responses were investigated to realize some basic properties which are very significant in assessing the fatigue life of skin soft tissue. The results show that a cyclic accumulation of peak and valley strain, which can be terminologically called as ratchetting in terms of material sci...

Flexibility of short DNA helices under mechanical stretching.

The flexibility of short DNA fragments is studied by a Hamiltonian model which treats the inter-strand and intra-strand forces at the level of the base pair. The elastic response of a set of homogeneous helices to externally applied forces is obtained by computing the average bending angles between adjacent base pairs along the molecular axis. The ensemble averages are performed over a room tem...

DNA under Hydrodynamic and Mechanical Stretching: Structure and Dynamics

Proliferation and collagen production of human patellar tendon fibroblasts in response to cyclic uniaxial stretching in serum-free conditions.

We studied the effect of cyclic mechanical stretching on the proliferation and collagen mRNA expression and protein production of human patellar tendon fibroblasts under serum-free conditions. The role of transforming growth factor-beta1 (TGF-beta1) in collagen production by cyclically stretched tendon fibroblasts was also investigated. The tendon fibroblasts were grown in microgrooved silicone...
