A design framework for gradually stiffer mechanical metamaterial induced by negative Poisson's ratio property

open access: yesMaterials & Design, 2020
Gradually stiffer (GS) mechanical metamaterial is a novel kind of adaptive structures under nonlinear varying loads for cushioning and vibration damping in engineering. These man-made metamaterials in applications are usually tailored by trial-and-error.

MiR-492 impairs the angiogenic potential of endothelial cells [PDF]

open access: yes, 2013
Endothelial cells growing in high glucose-containing medium show reduced cell proliferation and in vitro angiogenesis. Evidence suggests that the molecular pathways leading to these cellular responses are controlled by microRNAs, endogenous post ...
