Application of high-flow nasal cannula oxygen therapy in patient with pulmonary edema following cesarean-section under combined spinal-epidural anesthesia: A case report.

Background: High-flow nasal cannula (HFNC), which overcomes the disadvantages of the existing low flow mask, is an efficient method that can immediately provide a high volume of heated oxygen to the patient.[1] Therefore, this case reports a case in which HFNC was applied to a pregnant with acute respiratory failure.

Case: A 37-year-old woman pregnant (GA 30 + 5 weeks) with twin was diagnosed with preeclampsia.

Optical Tunneling Mediated Sub-Skin-Depth High Emissivity Tungsten Radiators.

Tailoring the spectrum of thermal radiation at high temperatures is a central issue in the study of thermal radiation harnessed energy resources. Although bulk metals with periodic cavities incorporated into their surfaces provide high emissivity, they require a complicated micron metal etch, thereby precluding reliable, continuous operation. Here, we report thermally stable, highly emissive, ultrathin (<20 nm) tungsten (W) radiators that were prepared in a scalable and cost-effective route.

Microstructured void gratings for outcoupling deep-trap guided modes.

Breaking the total internal reflection far above a critical angle (i.e., outcoupling deep-trap guided modes) can dramatically improve existing light-emitting devices.

Quick, large-area assembly of a single-crystal monolayer of spherical particles by unidirectional rubbing.

Rubbing a dry powder of particles in one direction between two rubbery substrates is found to be a quick and highly reproducible, yet inexpensive fabrication technique for assembling particle monolayers with perfect spatial registry on flat or curved surfaces. The optimum rubbing conditions - pressure and speed - for a single-crystal monolayer are shown to depend on particle size. Potential applications are in biosensors, photovoltaics, and light manipulators.

Mode tunable p-type Si nanowire transistor based zero drive load logic inverter.

A design platform for a zero drive load logic inverter consisting of p-channel Si nanowire based transistors, which controlled their operating mode through an implantation into a gate dielectric layer was demonstrated. As a result, a nanowire based class D inverter having a 4.6 gain value at V(DD) of -20 V was successfully fabricated on a substrate.

One-dimensional semiconductor nanostructure based thin-film partial composite formed by transfer implantation for high-performance flexible and printable electronics at low temperature.

Having high bending stability and effective gate coupling, the one-dimensional semiconductor nanostructures (ODSNs)-based thin-film partial composite was demonstrated, and its feasibility was confirmed through fabricating the Si NW thin-film partial composite on the poly(4-vinylphenol) (PVP) layer, obtaining uniform and high-performance flexible field-effect transistors (FETs). With the thin-film partial composite optimized by controlling the key steps consisting of the two-dimensional random dispersion on the hydrophilic substrate of ODSNs and the pressure-induced transfer implantation of them into the uncured thin dielectric polymer layer, the multinanowire (NW) FET devices were simply fabricated. As the NW density increases, the on-current of NW FETs increases linearly, implying that uniform NW distribution can be obtained with random directions over the entire region of the substrate despite the simplicity of the drop-casting method.

Secretory phospholipase A2 induces apoptosis through TNF-alpha and cytochrome c-mediated caspase cascade in murine macrophage RAW 264.7 cells.

Phospholipase A2 (PLA2) is an esterase that cleaves the sn-2 ester bond in glycerophospholipids, thereby releasing free fatty acids and lysophospholipids. In addition to the apoptotic activity of cytosolic PLA2 and Ca2+-independent PLA2, recent studies showed that secretory PLA2 (sPLA2) also play a role in apoptosis. However, the details of molecular mechanism have not been fully elucidated.
