Inflammation potentiates miR-939 expression and packaging into small extracellular vesicles

Journal of Extracellular Vesicles, 2019
Extracellular RNA in circulation mediates intercellular communication in normal and pathological processes. One mode of circulating miRNA transport in bodily fluids is within 30–150 nm small extracellular vesicles (sEVs) or exosomes.

Dynamics of turbulent flow over mobile dune

Flow
The present study reveals the turbulence dynamics and morphological adjustments of mobile dune-shaped bedforms in an alluvial stream. Results demonstrate acceleration of flow over the dune crest enhancing streamwise velocity, while the initial and the ...

Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis

Flow
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investigated, and moderate stagnation conditions are used to provide ...

Data-driven modelling for on-demand flow prescription in fan-array wind tunnels

Flow
Fan-array wind tunnels are an emerging technology to prescribe wind fields through grids of individually controllable fans. This design is especially suited for the turbulent, dynamic, non-uniform flow conditions found close to the ground, and has ...

MicroRNA-939 Directly Targets HDGF to Inhibit the Aggressiveness of Prostate Cancer via Deactivation of the WNT/β-Catenin Pathway

OncoTargets and Therapy, 2020
Purpose MicroRNA-939 (miR-939) has crucial roles in several types of human cancer. However, the expression profile and precise functions of miR-939 in prostate cancer (PCa) are still unclear.

Vortices produced by swirl-mixing grids in nuclear fuel assembly: a wind-tunnel experiment

Flow
Longitudinal vortices produced by a swirl-mixing grid are experimentally explored in an upscaled model of nuclear fuel assembly. The flow is mapped using particle image velocimetry in several planes downstream of the grid.
