Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

Marburg Virus Glycoprotein Is a Remarkable Virulent Factor Linked to Hemorrhagic Pathology: Evidence from Multimodal Experimental Systems

Advanced Science, EarlyView.
By integrating data from in vitro, ex vivo, and in vivo models, our research identifies the MARV glycoprotein as a remarkable hemorrhagic factor, filling a major gap in this important field. It also provides practical experimental tools for the basic research on viral pathogenesis and applied research aimed at antiviral intervention for hemorrhagic ...

Plasma production by laser

Physics Reports, 1973
Abstract A review of high density, high temperature plasma production with pulse lasers is presented. In view of possible applications to thermonuclear fusion we limit our discussion to plasma generation from solid targets of low atomic number Z, with particular emphasis on solid deuterium.

Thermal conductivity of a laser plasma

Physical Review E, 2023
We present a model of the electron thermal conductivity of a laser-produced plasma. The model, supported by Vlasov-Fokker-Planck simulations, predicts that laser absorption reduces conductivity by forcing electrons out of a Maxwell-Boltzmann equilibrium, which results in the depletion of both low-velocity bulk electrons and high-velocity tail electrons.

Plasma effects in the HCN laser

Applied Optics, 1974
The radial gain and refractive properties of an HCN amplifier using high current, short pulse excitation have been measured at 337 microm. The amplifier exhibits gain only after the electrons, which are produced at the wall, reach the amplifier axis, thus accounting for the delay normally observed between excitation and laser emission.

Laser beam-plasma coupling in laser solenoid plasmas

The Physics of Fluids, 1976
A model has been constructed to analyze the gross beam-plasma interaction in a laser solenoid plasma. The model includes a simple solution for a slab plasma response to a given laser beam, and a solution for axial beam size variations in response to arbitrary axial plasma structure.

INTERACTION OF LASER BEAMS WITH A PLASMA

Mathematical Models and Methods in Applied Sciences, 2009
In this paper, we construct a model for the propagation of two laser beams in a plasma. The originality of our model lies in the fact that it is valid uniformly in terms of the angle between both beams while it is not the case for standard models. In a simplified case we show that the solution converges towards the solution of the classical ones for ...
