Here, a rational design of a completely new family of halogen-free organic luminescent derivatives in amorphous matrices, displaying both conventional fluorescence and phosphorescence is reported. Hydrogen bonding between the newly developed emitters and an ethylene-vinyl alcohol copolymer (Exceval) matrix, which efficiently suppresses vibrational dissipation, enables bright long-lived phosphorescence with lifetimes up to 2.6 s at around 480 nm. The importance of the chosen matrix is shown as well as the implementation in an organic programmable luminescent tag. © 2020 The Authors. Published by WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.As a thriving member of the 2D nanomaterials family, MXenes, i.e., transition metal carbides, nitrides, and carbonitrides, exhibit outstanding electrochemical, electronic, optical, and mechanical properties. They have been exploited in many applications including energy storage, electronics, optoelectronics, biomedicine, sensors, and catalysis. Compared to other 2D materials, MXenes possess a unique set of properties such as high metallic conductivity, excellent dispersion quality, negative surface charge, and hydrophilicity, making them particularly suitable as inks for printing applications. Printing and pre/post-patterned coating methods represent a whole range of simple, economically efficient, versatile, and eco-friendly manufacturing techniques for devices based on MXenes. Moreover, printing can allow for complex 3D architectures and multifunctionality that are highly required in various applications. By means of printing and patterned coating, the performance and application range of MXenes can be dramatically increased through careful patterning in three dimensions; thus, printing/coating is not only a device fabrication tool but also an enabling tool for new applications as well as for industrialization. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The eicosanoid lipoxin A4 and aspirin-triggered 15-epi-lipoxin A4 (ATL) are potent anti-inflammatory agents. How their anti-inflammatory effects are mediated by receptors such as the formyl peptide receptor 2 (FPR2/ALX) remains incompletely understood. In the present study, fluorescent biosensors of FPR2/ALX were prepared and ATL-induced conformational changes were recorded. A biphasic dose curve consisting of a descending phase and an ascending phase was observed, with the descending phase corresponding to diminished FPR2 response such as Ca2+ mobilization induced by the potent synthetic agonist WKYMVm. Preincubation of FPR2-expressing cells with 100 pM of ATL also lowered the threshold for WKYMVm to induce β-arrestin-2 membrane translocation, and inhibited WKYMVm-induced interleukin 8 secretion, suggesting signaling bias favoring anti-inflammatory activities. At 100 pM and above, ATL-induced receptor conformational changes resembling that of the WKYMVm along with a weak but measurable inhibition of forskolin-induced cAMP accumulation. However, no Ca2+ mobilization was induced by ATL until its concentration reached 1 µM. Taken together, these results suggest a dual regulatory mechanism by which ATL exerts anti-inflammatory effects through FPR2/ALX. © 2020 Federation of American Societies for Experimental Biology.BACKGROUND The Veterans Health Administration (VHA) Opioid Safety Initiative (OSI) was implemented in 2013 and was associated with a 25% relative decrease in the dispensing of opioids. Although Emergency Department (ED) providers play a role in the initiation and continuation of opioids, the incumbent OSI did not target EDs. OBJECTIVE The goal of this feasibility study was to leverage the existing VHA OSI and test a novel ED-based quality improvement (QI) program to decrease opioid prescribing in multiple ED settings. METHODS This was a quasi-experimental study of phased-in implementation of a quality improvement ED-based OSI. The general setting for this pilot were four VHA EDs across the Veterans Integrated Services Network (VISN) region 19 Denver, Oklahoma City, Muskogee, and Salt Lake City. We developed and disseminated a dashboard to assess ED-specific prescribing rates and an ED-tailored toolkit to implement the program. Academic Detailing pharmacists provided focused audits-and-feedback with the highesOver the past 20 years, multiple studies have demonstrated the superiority of percutaneous catheter-based pulmonary vein isolation (PVI) in the management of atrial fibrillation (AF). Unfortunately, the results of catheter ablation can be limited by arrhythmia recurrence, which is often a result of a failure to achieve durable lesions around the pulmonary vein ostia. In response, significant efforts have been directed toward developing technologies to achieve safer and more durable PVI, including the development of dedicated catheters capable of achieving PVI with a single ablation lesion (eg, the Arctic Front Cryoballoon; Medtronic CryoCath, Pointe-Claire, Canada). The purpose of this review is to discuss the contemporary role of cryoballoon ablation in the invasive management of AF, with a focus on the characteristics that differentiate cryoballoon from radiofrequency ablation. © 2020 Wiley Periodicals, Inc.High-energy Li-rich layered cathode materials (≈900 Wh kg-1 ) suffer from severe capacity and voltage decay during cycling, which is associated with layered-to-spinel phase transition and oxygen redox reaction. Current efforts mainly focus on surface modification to suppress this unwanted structural transformation. However, the true challenge probably originates from the continuous oxygen release upon charging. Here, the usage of dielectric polarization in surface coating to suppress the oxygen evolution of Li-rich material is reported, using Mg2 TiO4 as a proof-of-concept material. The creation of a reverse electric field in surface layers effectively restrains the outward migration of bulk oxygen anions. Meanwhile, high oxygen-affinity elements of Mg and Ti well stabilize the surface oxygen of Li-rich material via enhancing the energy barrier for oxygen release reaction, verified by density functional theory simulation. Benefited from these, the modified Li-rich electrode exhibits an impressive cyclability with a high capacity retention of ≈81% even after 700 cycles at 2 C (≈0.
