A Royal Jelly Mixture with Berberine for Dressing Change on a Refractory Skin Ulcer: A Case Report

It has been reported that a 92-year-old female had got a bruise superficialwound on her right leg one and a half years ago, developing into refractoryskin ulcer due to improper management before. A prepared cream, mixedroyal jelly with berberine for dressing change, was made on the scenethrough the crush of berberine tablets, working with fresh royal jelly.Topical dressing change with the cream was done every 3 days, and twomonths later, such the ulcer became clean and was covered fully with freshgranulation tissue. This kind of cream consists of the ingredients of TCMpurely, free of antibiotic, and being quite effective clinically, also helpfulfor proper use of antibiotic

An Introduction of the Vaporized Therapy with Tea Herb Drink for Relieving Agitation due to Pulmonary Encephalopathy

What methods would you choose apart from increasing sedatives foragitation in an advanced patient with hypercapnic encephalopathy dueto AECOPD? This is a 94-year-old female who suffered from COPD forover 30 years, occurred with an accelerated episode of cough, productivesputum and a dropping down to 86% in SatO₂ due to a cold weather. Adiagnosis of pulmonary encephalopathy (PE) was made on the basis of thesubsequent agitation and delirium, and the sedatives, such as quatiepineand haloperidol, had to be given for her mental excitation respectively, butshe still pulled out indwelling needle herself and refused to any infusiontherapy. As an alternative, a vaporized therapy integrated with tea herbdrinking had to be applied to relieving her agitation, being designedas the vaporization of the inhaled oxygenation by means of high-flowoxygenation device (HFOD), with an ampoule of ambroxol mixed into theinhaler and simultaneous drinking of TCM tea herb for reducing sputum,helping dissolve the mucoid bolts inside her terminal bronchioles whenbeing infected. We thought that a better efficacy would be achieved forhypercapnic encephalopathy due to AECOPD if we concentrate on a goodventilation of small airway through the vaporized therapy

High optical transmittance of aluminum ultrathin film with hexagonal nanohole arrays as transparent electrode

We fabricate samples of aluminum ultrathin films with hexagonal nanohole arrays and characterize the transmission performance. High optical transmittance larger than 60% over a broad wavelength range from 430 nm to 750 nm is attained experimentally. The Fano-type resonance of the excited surface plasmon plaritons and the directly transmitted light attribute to both of the broadband transmission enhancement and the transmission suppression dips

A gate-variable spin current demultiplexer based on graphene

Spintronics, which utilizes spin as information carrier, is a promising solution for nonvolatile memory and low-power computing in the post-Moore era. An important challenge is to realize long distance spin transport, together with efficient manipulation of spin current for novel logic-processing applications. Here, we describe a gate-variable spin current demultiplexer (GSDM) based on graphene, serving as a fundamental building block of reconfigurable spin current logic circuits. The concept relies on electrical gating of carrier density dependent conductivity and spin diffusion length in graphene. As a demo, GSDM is realized for both single-layer and bilayer graphene. The distribution and propagation of spin current in the two branches of GSDM depend on spin relaxation characteristics of graphene. Compared with Elliot-Yafet spin relaxation mechanism, D'yakonov-Perel mechanism results in more appreciable gate-tuning performance. These unique features of GSDM would give rise to abundant spin logic applications, such as on-chip spin current modulators and reconfigurable spin logic circuits.Comment: 18 pages,3 figures,1 tabl

Field-free spin-orbit torque-induced switching of perpendicular magnetization in a ferrimagnetic layer with vertical composition gradient

Current-induced spin-orbit torques (SOTs) are of interest for fast and energy-efficient manipulation of magnetic order in spintronic devices. To be deterministic, however, switching of perpendicularly magnetized materials by SOT requires a mechanism for in-plane symmetry breaking. Existing methods to do so involve the application of an in-plane bias magnetic field, or incorporation of in-plane structural asymmetry in the device, both of which can be difficult to implement in practical applications. Here, we reported bias-field-free SOT switching in a single perpendicular CoTb layer with an engineered vertical composition gradient. The vertical structural inversion asymmetry induces strong intrinsic SOTs and a gradient-driven Dzyaloshinskii-Moriya interaction (g-DMI), which breaks the in-plane symmetry during the switching process. Micromagnetic simulations are in agreement with experimental results, and elucidate the role of g-DMI in the deterministic switching. This bias-field-free switching scheme for perpendicular ferrimagnets with g-DMI provides a strategy for efficient and compact SOT device design.Comment: 27 pages, 5 figure
