Development of a uniaxial mechanical loading device to evaluate osteogenic differentiation of stem cells seeded on a scaffold material

2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2015
The present study was designed to investigate the effect of the uniaxial mechanical strain on the proliferation and differentiation of mouse mesenchymal stem D1 cells seeded into the octacalcium phosphate (OCP)/ Gelatin (Gel) composite in vitro. The mechanical stimulation with a uniaxial loading device was analyzed by finite element analysis in order ...

Tunneling injection into modulation doping structures: a mechanism for negative differential resistance three-terminal high-speed devices

IEEE Transactions on Electron Devices, 1988
A tunneling injection mechanism into the channel of a modulation doping field effect transistor is discussed. In the presaturation regime of the drain current, the source current exhibits negative differential resistance as a result of the charge control by the gate field in the channel.

Controlled Drug Release from Polymeric Delivery Devices II: Differentiation Between Partition-Controlled and Matrix-Controlled Drug Release Mechanisms

Journal of Pharmaceutical Sciences, 1974
The drug release pattern of micronized ethynodiol diacetate from silicone devices was thoroughly investigated in polyethylene glycol-containing elution media with a wide range of solubility and partition properties. When high drug solubility was maintained, the drug release pattern followed a Q - t1/2 relationship (matrix controlled). Under this matrix-

Increase in Frequency of Terminally Differentiated and Exhausted CD8+ T Cells Is Associated with Worse Clinical Outcomes after Mechanical Circulatory Support Device Implantation

The Journal of Heart and Lung Transplantation, 2016
LVAD+Pulsatility immediately post-OHT, with partial attenuation of this difference by 6 months, and normalization by 12 months post-OHT. Conclusion: Aortic stiffness is markedly increased immediately post-OHT among patients bridged with CF-LVADs, with attenuation of this increased stiffness over the first year after transplant.

The negative differential resistance mechanism of a molecular device based on double‐cage fluorinated fullerene C20F18(NH)2C20F18: A theoretical study

International Journal of Quantum Chemistry, 2018
AbstractThe electronic transport properties of the molecular device based on double‐cage fluorinated fullerene C20F18(NH)2C20F18 were studied theoretically. The results show that the device exhibits two negative differential resistance (NDR) peaks in its I‐V curve.

Impact of Magneto‐Mechanical Actuation on Cell Differentiation: A Study Using Wireless, 3D‐Printed Device and a Porous Ferrogel

Small
AbstractCells perceive external and internally generated forces of different kinds, significantly impacting their cellular biology. In the relatively nascent field of mechanobiology, the impact of such forces is studied and further utilized to broaden the knowledge of cellular developmental pathways, disease progression, tissue engineering, and ...

New Biaxial Compression Test Device for Metallic Materials with Reverse-Type Differential Rotary to Linear Conversion Mechanism

Applied Mechanics and Materials, 2011
New rotary to linear conversion mechanism named "reverse-type differential rotary to linear conversion mechanism (RDRLCM)" was invented for simultaneous achievement of large load capacity and precise displacement control, for compression test devices and press forming machines. The new mechanism was developed and incorporated as loading systems into an
