Examination of Mechanical Stretching to Increase Alignment in Carbon Nanotube Composites
… State University (FSU). Through the use of mechanical stretching procedures to increase the alignment of the nanotubes within the CNT sheets, the tensile strength and Young's modulus of the composites in the FSU study averaged 3081 MPa and 350 GPa, respectively. These values are for …

The interplay of matrix rigidity and mechanical stretching for the development of artificial skin
… vessel, cartilage and bone but they lack the mechanical properties and biological functionality of their real counterparts which leads to failure in vivo. Matrix rigidity and mechanical forces are key regulators of tissue homeostasis and are essential for tissue formation, remodeling and …

Effect of mechanical stretching on the maturation of 3-D fascicle-like muscle tissue
… muscle is well known for a rapid adaptation to mechanical environmental changes. Understanding the effects of the mechanical stimulation such as stretching to muscle tissues is important for understanding the nature of muscle development and muscle diseases. While there are many reports studying …

Stretch induced hyperexcitability of mice callosal pathway
… nervous system plasticity is also sensitive to mechanical stretch. This is important, given the host of clinical conditions involving changes in mechanical tension on the brain, and the normal role that mechanical tension plays in brain development. A novel platform is developed to investigate …

1D-to-3D transition of photon heat conduction in polyethylene using molecular dynamics simulations
Experiments have demonstrated that the mechanical stretching of bulk polyethylene can increase its thermal conductivity by more than two orders of magnitude, from 0.35 W/mK to over 40W/mK, which is comparable to steel. This strong effect is believed to arise from the increased alignment of the …

The role of autophagy in protecting periodontium integrity, and lipopolysaccharide-induced osteoclast differentiation
… that autophagy can be activated by both mechanical stretching and inflammation, however the mechanisms involved are highly context dependent. Autophagy may also be important for bone remodeling in the oral cavity. Two scenarios where bone remodeling is key to the physiological outcome are …

Investigating Mechanotransduction and Mechanosensitivity in Mammalian Cells
… clear that cells are also influenced by the mechanical forces and mechanical properties of the local microenvironment. Extracellular forces causing cellular deformation can originate from many sources, such as fluid shear stresses arising from interstitial or blood flow, mechanical stretching …

Modulation of mesenchymal stem cell invasion into decellularized engineered tissues
Mechanical forces play an important role in shaping the organization and alignment of the extracellular matrix (ECM) in developing and mature tissues, where the organization gives the tissue its unique functional properties. This dissertation will discuss research that is fundamental to the …

Transparent Tissues and Porous Thin Films: A Brillouin Light Scattering Study
… difficult with traditional techniques such as mechanical stretching and nanoindentation being ineffective at these spatial length scales. In this thesis, Brillouin light scattering is shown to offer an effective approach to accurately measure the elastic properties of transparent tissues within …

Effects of GATA4-targeted compounds in hypertrophic models of hypoplastic left heart syndrome cardiomyocytes
Synnynnäiset sydänviat kehittyvät sydämen kehityksen aikana ja määritellään syntymähetkellä läsnä oleviksi sydämen rakenteellisiksi poikkeavuuksiksi, joista vasemman sydänpuoliskon vajaakehittyneisyysoireyhtymä (HLHS) edustaa harvinaista mutta hengenvaarallista alatyyppiä. HLHS:lle on ominaista …
