Exhaustion within Children regarding Auto-immune Encephalitis.
Low-density lipoprotein cholesterol (LDL-C) is usually considered as a "bad cholesterol" for it is one of the major risk factors for coronary heart disease. As a scavenger of LDL-C, the low density lipoprotein receptor (LDLR) binds with LDL-C in the liver. However, the protein levels and function of LDLR are regulated by Proprotein convertase subtilisin/kexin type 9 (PCSK9). Loss of PCSK9 induces the increase of LDLR levels and reduction of plasma LDL-C. Here, we developed a novel style of artificial platelets with biomimetic properties, high stability, and long circulation which enabled the efficient delivery of siRNA targeting Pcsk9. The bioinspired nanoparticles induced Pcsk9 mRNA reduction by 66% in vitro. Xevinapant cost For in vivo studies, the nanoparticles accumulated in the liver to reduce Pcsk9 transcription, which results in ∼28% reduction in plasma LDL-C concentrations with negligible effects on either high density lipoprotein cholesterol (HDL-C) or triglycerides (TGs). These results demonstrated the use of artificial platelets to deliver siRNA and induce effective RNAi therapeutics to specifically lower LDL-C which provides a potential strategy to lower PCSK9 and treat hypercholesterolemia.In this study, a highly flexible, patternable multiwalled-carbon nanotube (MWCNT) paper electrode was specially designed and fabricated. The addition of a nitrocellulose (NC) polymer binder at less than the critical amount (≤2 wt %) was found to be effective for maintaining both the flexibility and electrical conductance of the resulting MWCNT paper electrode. The fabricated MWCNT paper electrode was then employed as a heating platform to ignite Al/CuO nanoparticle-based nanoenergetic materials (nEMs). The nEM layer was drop-cast on the surface of the MWCNT paper electrode with specially patterned shapes using a plotter, and its ignition was evaluated by applying various voltages through the MWCNT paper electrode. To increase the adhesion between the nEM layer and MWCNT paper electrode and to decrease the sparking sensitivity of the nEM layer, it was essential to incorporate NC in the nEM matrix. However, the combustion and explosion properties of nEM layers deteriorated with the addition of NC, enabling the estimation of the optimum amount of NC to be incorporated. The fabricated igniter can be employed in various thermal engineering applications, such as in the ignition of explosives and propellants, and in pyrotechnics. To demonstrate this, a compact, flexible, and patternable igniter composed of the NC/nEM layer (NC/nEM = 28 wt %) on an MWCNT paper electrode was used to successfully ignite solid propellants for launching a small rocket.Lithium (Li) metal is among the most promising anode materials for next-generation rechargeable batteries. However, inevitable Li dendrite growth and huge volume expansion severely restrict its practical application. Here, we propose a melamine sponge@silver nanowires (MS@AgNWs) current collector to achieve highly reversible Li storage. By combining the strength advantages of lithophilic nanoseeds, 3D current rectification structure and stress-releasing soft substrate, the MS@AgNWs host can successfully release the compress stress generated during the Li-plating process and hence give rise to uniform Li deposition. In particular, the MS@AgNWs-Li composite anode shows high Coulomb efficiency of 99.1% over 300 cycles and ultralow overpotentials of 10 mV at 1 mA cm-2 and 19 mV at 2 mA h cm-2. Superior long-term cycle stability over 1000 h is attained in symmetric cell under various densities. The assembled full cells with LiFePO4 cathode deliver excellent cycle performance with capacity retention of 138.2 mAh g-1 at 1C after 400 cycles and outstanding rate performance (discharge capacity of 119 mAh g-1 at 10 C). Scalable fabrication of 3D MS@AgNWs flexible host can be easily realized, which is potential for developing practical flexible Li metal based batteries.Conventional systemic chemotherapeutic regimens suffer from challenges such as nonspecificity, shorter half-life, clearance of drugs, and dose-limiting toxicity. Localized delivery of chemotherapeutic drugs through noninvasive spatiotemporally controllable stimuli-responsive drug delivery systems could overcome these drawbacks while utilizing drugs approved for cancer treatment. In this regard, we developed photoelectro active nanocomposite silk-based drug delivery systems (DDS) exhibiting on-demand drug release in vivo. A functionally modified single-walled carbon nanotube loaded with doxorubicin (DOX) was embedded within a cross-linker free silk hydrogel. The resultant nanocomposite silk hydrogel showed electrical field responsiveness and near-infrared (NIR) laser-induced hyperthermal effect. The remote application of these stimuli in tandem or independent manner led to the increased thermal and electrical conductivity of nanocomposite hydrogel, which effectively triggered the intermittent on-demand drug release. In a proof-of-concept in vivo tumor regression study, the nanocomposite hydrogel was administered in a minimally invasive way at the periphery of the tumor by covering most of it. During the 21-day study, drastic tumor regression was recorded upon regular stimulation of nanocomposite hydrogel with simultaneous or individual external application of an electric field and NIR laser. Tumor cell death marker expression analysis uncovered the induction of apoptosis in tumor cells leading to its shrinkage. Heart ultrasound and histology revealed no cardiotoxicity associated with localized DOX treatment. To our knowledge, this is also the first report to show the simultaneous application of electric field and NIR laser in vivo for localized tumor therapy, and our results suggested that such strategy might have high clinical translational potential.Noncompressible torso hemorrhage accounts for a significant portion of preventable trauma deaths. We report here on the development of injectable, targeted supramolecular nanotherapeutics based on peptide amphiphile (PA) molecules that are designed to target tissue factor (TF) and, therefore, selectively localize to sites of injury to slow hemorrhage. Eight TF-targeting sequences were identified, synthesized into PA molecules, coassembled with nontargeted backbone PA at various weight percentages, and characterized via circular dichroism spectroscopy, transmission electron microscopy, and X-ray scattering. Following intravenous injection in a rat liver hemorrhage model, two of these PA nanofiber coassemblies exhibited the most specific localization to the site of injury compared to controls (p less then 0.05), as quantified using immunofluorescence imaging of injured liver and uninjured organs. To determine if the nanofibers were targeting TF in vivo, a mouse saphenous vein laser injury model was performed and showed that TF-targeted nanofibers colocalized with fibrin, demonstrating increased levels of nanofiber at TF-rich sites.
