Leaflet Thickening or Immobility Following Aortic Valve Replacement: Results from the Evolut Low Risk Sub-study.

Journal of the American College of Cardiology, 2020
BACKGROUND Subclinical leaflet thrombosis has been reported after bioprosthetic aortic valve replacement, characterized using 4-dimensional computed tomographic (CT) imaging by hypoattenuated leaflet thickening (HALT) and reduced leaflet motion (RLM ...

Multi-Layered Regulation of Plant Cell Wall Thickening.

Plant and Cell Physiology, 2021
Plants need to develop thickened cell walls with appropriate localization through precise regulation during the process of growth and development in order to support their body weight and to build long distance transportation systems.

Coordination between root cell wall thickening and pectin modification is involved in cadmium accumulation in Sedum alfredii.

Environmental Pollution, 2020
Root cell wall (RCW) modification is a widespread important defense strategy of plant to cope with trace metals. However, mechanisms underlying its remolding in cadmium (Cd) accumulation are still lacking in hyperaccumulators.

Effect of dispersing media and temperature on inter-yarn frictional properties of Kevlar fabrics impregnated with shear thickening fluid

, 2020
Shear thickening fluid (STF) treated Kevlar fabrics is a potential method to improve the stab resistance of flexible body armors, whereas the STFs were significantly influenced by the temperature during their practical application.

Evaluation of gallbladder wall thickening: a multimodality imaging approach

Expert Review of Gastroenterology & Hepatology, 2020
Introduction Gallbladder (GB) wall thickening is a relatively common finding on imaging. While there are clear recommendations for the management of gallstones, GB wall thickening presents a significant challenge. Despite advances in radiological as well

Conductive shear thickening gel/Kevlar wearable fabrics: A flexible body armor with mechano-electric coupling ballistic performance

Composites Science And Technology, 2019
This work reported a novel conductive shear thickening gel-Kevlar fabrics (c-STG/Kevlar) body armor material which possessed both anti-impact performance and dynamic mechano-sensing behavior. Due to the excellent shear thickening effect, the c-STG/Kevlar

Development of novel guar gum hydrogel based media for abrasive flow machining: Shear-thickening behavior and finishing performance

International Journal of Mechanical Sciences, 2019
Abrasive flow machining (AFM) is a non-traditional finishing method by extruding abrasive media through workpieces’ surfaces. In AFM process, the machining capacity of traditional shear-thinning media will be reduced with the decline of viscosity at high
