The Role of Pulse Energy On Laser Induced Secondary Plasma Generation [PDF]

, 2005
An observation about the role of laser pulse energy on the secondary plasma generation has been point out. The plasma emission intensity as a function of laser pulse energy was detected by using a monochromator combined with photomultiplier tube.

Laminar shocks in high power laser plasma interactions

, 2013
We propose a theory to describe laminar ion sound structures in a collisionless plasma. Reflection of a small fraction of the upstream ions converts the well known ion acoustic soliton into a structure with a steep potential gradient upstream and with ...

The influence of laser assistance on the machinability of the titanium alloy Ti555-3 [PDF]

, 2013
The Ti533-3 alloy is a new titanium alloy which is starting to see increased use in the aeronautical domain to improve the durability of components and to optimize the weight/resistance ratio. This alloy is characterized by greater resistance compared to

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

Scaling of Laser-Plasma Interactions with Laser Wavelength and Plasma Size [PDF]

, 1984
Laboratory experiments on the wavelength scaling of laser-plasma interactions have thus far been restricted to relatively modest laser energies (EL ≤ 200 J), short pulse lengths (τL ≤ 2 nsec), and small focal spot diameters (d ≲, 200 µm). Thus the plasma sizes have been quite modest.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly
