Valpromide increases amplitude of heart rate circadian rhythm in remitted bipolar and unipolar disorders.A placebo-controlled study
Authors: Lemoine P , Fondarai J , Faivre T 
Published: July 2002

The aim of this study was to investigate for the effects of valpromide on heart rate circadian rhythm in remitted recurrent unipolar and bipolar disorders (DSM-III-R). It consisted of a comparative, randomized, double-blind, repeated cross-over study of valpromide versus placebo over four four-week periods. The primary evaluation criteria was heart rate (HR). Secondary criteria comprised motor activity (MA) and the Bech and Rafaelsen mania assessment scale, Horne and Ostberg questionnaire, Montgomery and Asberg depression rating scale, Spiegel questionnaire, a sleep diary, and Clinical Global Impression. Fifteen patients were included, giving 60 one-month periods (30 valpromide periods and 30 placebo periods).Cosinor analysis of HR and MA data revealed a difference in amplitude (P = 0.037, analysis of variance, one-tailed test).The clinical sleep study shows that the duration of sleep was greater with valpromide than with placebo (P = 0.007, one-tailed test). Similarly, evaluation of the quality of sleep by patients themselves showed valpromide to be superior to placebo (P = 0.045, one-tailed test). The results of analysis of the Spiegel questionnaire also confirm the superiority of valpromide over placebo. Safety and compliance were comparable for the active drug and the placebo.In conclusion, the relatively small sample size requires cautious interpretation of this study. Nevertheless, these initial results show a definite effect of valpromide on a biological rhythm that leads one to suppose that it may be effective through a ‘synchronizing’ effect.

Abstract

Objectives
The cross-sectional study aimed to analyze the association between burnout, work-related factors, and metabolic syndrome (Mets) in nurses from several departments of a tertiary hospital in Taiwan. Exploring biomarkers could provide for prevention.

Methods
Demographic data were obtained through a written questionnaire and include the following information: gender, age, education level, psychosocial and work situations, such as departments, working hours, work shift, depression, and sleep time. Burnout was evaluated according to the Chinese Burnout inventory, Mets was evaluated according to the criteria of the National Cholesterol Education Program of Taiwan—Treatment Panel for Adults III (NCEP-ATP III).

Results
A total of 1758 nurses participated with a median age of 35.2 years. The prevalence of burnout and Mets was 6.4% and 13.84%, respectively. The results showed that burnout induced higher risk of Mets, odds ratio (OR) 1.70 (95% confidence interval, 1.04-3.05). Other factors, such as out-patient nurses, seniority (4-10 and &gt;10 years), working hours (51-59 h/wk), nigh shift, Brief Symptom Rating Scale-5 (score 10-14 and ≧15), poor self-rated health status, and inadequate sleep time, led to higher risk of Mets. Biomarkers research showed that Glycated hemoglobin (Hba1c) was significantly associated with burnout nurses (OR = 24.72, P &lt; .001), but thyroid-stimulating hormone and free thyroxin were not.

Conclusions
Results suggested positive associations between burnout and Mets in nurses. For nurses with higher seniority, long hours of work, night shifts, poor physical and mental conditions, and poor lifestyle habits in different departments, strategies are needed to prevent burnout and Mets.

AbstractThis article presents a quasi‐experimental intervention study designed to reduce the level of verbal aggression on a social networking service (Reddit). The interventions were based on three psychological mechanisms: induction of a descriptive norm, induction of a prescriptive norm, and empathy induction. Each intervention was generated using a communicating bot. Participants exposed to these interventions were compared with a control group that received no intervention. The bot‐generated normative communications (both the ones priming descriptive and the ones priming prescriptive norms), as well as the empathizing intervention, reduced the proportion of verbal aggression posted by Reddit accounts. All three interventions proved effective in reducing verbal violence when compared with the control condition.

AbstractThis article reports damping enhancement in a ferromagnetic NiFe thin film due to an adjacent α‐Sn thin film. Ferromagnetic resonance studies show that an α‐Sn film separated from a NiFe film by an ultrathin Ag spacer can cause an extra damping in the NiFe film that is three times bigger than the intrinsic damping of the NiFe film. Such an extra damping is absent in structures where the α‐Sn film interfaces directly with a NiFe film, or is replaced by a β‐Sn film. The data suggest that the extra damping is associated with topologically nontrivial surface states in the topological Dirac semimetal phase of the α‐Sn film. This work suggests that, like topological insulators, topological Dirac semimetal α‐Sn may have promising applications in spintronics.

Published: January 2021

AbstractInP quantum dots (QDs) are emerging as promising materials for replacing cadmium‐based QDs in view of their heavy metal‐free and tunable luminescence. However, the development of InP QD materials still lags due to the expensive and flammable phosphorus precursors, and also the unsatisfactory repeatability caused by the fast nucleation rate. Adopting lowly reactive P precursor aminophosphine can overcome this issue, but their low photoluminescence quantum yield (PLQY) and widening line widths do not apply to the practical application. Through engineering, the core‐shell structure of QD, significantly promoted green emissions of QDs were obtained with PLQY of 95% and full width and half maximum (FWHM) of 45 nm, which demonstrated the highest PLQY record obtained from the aminophosphine system. Moreover, due to the residue halogen atoms on the QD surface as inorganic ligands to prevent further oxidization, these InP QDs demonstrated the ultra‐long operational lifetime (over 1000 h) for QDs based color enhancement film. By optimizing the device structure, an inverted green InP quantum dot light‐emitting diode (QLED) with external quantum efficiency (EQE) of 7.06% was also demonstrated, which showed a significant promise of these InP QDs in highly effective optoelectronic devices.
Direction‐Controllable Plasmonic Color Scanning by Using Laser‐Induced Bubbles

AbstractBecause of the subwavelength pixel resolution, long‐term stability, and radiation resistance, plasmonic colors show great potential applications in high‐resolution color display, high‐density information storage, and stable color printing. Herein, laser‐induced bubbles are used to realize time‐ and direction‐controllable plasmonic color scanning in a metallic nanohole array, which can give rise to plasmonic colors. When the environment is changed from air to water, the peak wavelength of the metallic nanohole array is redshifted by ≈146 nm, and the color of the metallic nanohole array is changed from purple to yellow. Experimentally, these color changes are demonstrated when the water gradually covers the metallic nanohole array. More importantly, by using laser‐induced bubbles, time‐ and direction‐controllable plasmonic color scanning is achieved by controlling the movement speeds and positions of a control laser. Compared to the current state‐of‐the‐art plasmonic color scanning technology, the scanning time by using laser‐induced bubbles decreases by four orders of magnitude for the same scanning length. The time‐ and direction‐controllable color scanning provides additional degrees of freedom (scanning time and scanning direction), and it may have potential applications in information display, security, storage, and encoding.
Reactive Oxygenated Species Generated on Iodide‐Doped BiVO4/BaTiO3 Heterostructures with Ag/Cu Nanoparticles by Coupled Piezophototronic Effect and Plasmonic Excitation

Published: January 2021

AbstractAn effective generation of reactive oxygen species (ROS) is of interest from the perspective of environmental technology and industrial chemistry, and here piezocatalysis and photocatalysis using heterostructures based on iodide‐doped BiVO4/BaTiO3 with photodeposited Ag or Cu nanoparticles (BiVO4:I/BTO‐Ag or BiVO4:I/BTO‐Cu) is studied. The generation rates of •OH and •O2− radicals over BiVO4:I/BTO‐Ag during piezophotocatalysis are 371 and 292 µmol g−1 h−1, respectively, and significantly higher than those of sole piezocatalysis and photocatalysis. These rates are among the highest reported for the production of free radicals with the piezophototronic effect. Among the catalysts, BiVO4:I/BTO shows the highest reactivity for the production of H2O2 in piezocatalysis (with a concentration of 468 µm after 100 min of irradiation, and still constantly increasing). On BiVO4:I/BTO‐Ag and BiVO4:I/BTO‐Cu, it seems that redundant electrons and holes had reacted effectively with the generated H2O2 and in turn had reduced their activities; however, the amounts of H2O2 that are formed on BiVO4:I/BTO‐Ag or BiVO4:I/BTO‐Cu under piezophotocatalysis are superior to those of individual piezocatalysis and photocatalysis. A piezophototronic coupling via an ultrasound‐mediated and piezoelectric‐based polarization field and photoexcitation accounting for the enhanced photocatalytic activity of the iodine‐doped heterostructures with plasmonically sized Ag or Cu nanoparticles is suggested.
Photoreversible Loading and Unloading of Q–Silsesquioxane Dynamic Network Sponges
Authors: Hu Nai–hsuan , Furgal Joseph Coy 
Published: January 2021

AbstractThe synthesis and mechanical properties of photoswitchable silsesquioxane/azobenzene hybrid 3D‐polymers (“dynamic sponges”) are presented and discussed. The hybrid is capable of extensive macroscopic movement, and overcomes previously problematic crosslink locking issues. A hydride‐functionalized Q‐type silsesquioxane (Q8M8H) is reacted with di‐allyloxyazobenzene using hydrosilylation methods. The properties of the resulting materials are controlled via careful choice of starting material ratios and solvent, leading to gels or films. Both morphologies show pronounced photoresponsive behavior in and on the surfaces of different solvents. Photoactuation is tracked by microscopy, dynamic mechanic analysis, and UV–vis spectroscopy. The gel system has a porous structure similar to a sponge. It undergoes shrinkage in volume by 18.3% in toluene under UV irradiation, and shows excellent recovery to the swollen state after irradiation with visible light. These novel photodynamic materials offer reversible modulus switching from 160 kPa in the swollen state to 500 kPa in the “wrung‐out” sponge. The sponges can engage in uptake and release of a range of substances (i.e., reversible hydrophobic sponging), with overall performance determined by solvent specific quantities such as polarity and size. Such behavior gives these materials high potential for soft robotics applications and great promise as reusable environmental remediators.

Published: January 2021

AbstractWith the rapid growth in energy consumption, renewable energy is a promising solution. However, renewable energy (e.g., wind, solar, and tidal) is discontinuous and irregular by nature, which poses new challenges to the new generation of large‐scale energy storage devices. Rechargeable batteries using aqueous electrolyte and multivalent ion charge are considered more suitable candidates compared to lithium‐ion and lead‐acid batteries, owing to their low cost, ease of manufacture, good safety, and environmentally benign characteristics. However, some substantial challenges hinder the development of aqueous rechargeable multivalent ion batteries (AMVIBs), including the narrow stable electrochemical window of water (≈1.23 V), sluggish ion diffusion kinetics, and stability issues of electrode materials. To address these challenges, a range of encouraging strategies has been developed in recent years, in the aspects of electrolyte optimization, material structure engineering and theoretical investigations. To inspire new research directions, this review focuses on the latest advances in cathode materials for aqueous batteries based on the multivalent ions (Zn2+, Mg2+, Ca2+, Al3+), their common challenges, and promising strategies for improvement. In addition, further suggestions for development directions and a comparison of the different AMVIBs are covered.

AbstractThe development of all‐solid‐state Li metal batteries (ASSLMBs) has attracted significant attention due to their potential to maximize energy density and improved safety compared to the conventional liquid‐electrolyte‐based Li‐ion batteries. However, it is very challenging to fabricate an ideal solid‐state electrolyte (SSE) that simultaneously possesses high ionic conductivity, excellent air‐stability, and good Li metal compatibility. Herein, a new glass‐ceramic Li3.2P0.8Sn0.2S4 (gc‐Li3.2P0.8Sn0.2S4) SSE is synthesized to satisfy the aforementioned requirements, enabling high‐performance ASSLMBs at room temperature (RT). Compared with the conventional Li3PS4 glass‐ceramics, the present gc‐Li3.2P0.8Sn0.2S4 SSE with 12% amorphous content has an enlarged unit cell and a high Li+ ion concentration, which leads to 6.2‐times higher ionic conductivity (1.21 × 10−3 S cm−1 at RT) after a simple cold sintering process. The (P/Sn)S4 tetrahedron inside the gc‐Li3.2P0.8Sn0.2S4 SSE is verified to show a strong resistance toward reaction with H2O in 5%‐humidity air, demonstrating excellent air‐stability. Moreover, the gc‐Li3.2P0.8Sn0.2S4 SSE triggers the formation of Li–Sn alloys at the Li/SSE interface, serving as an essential component to stabilize the interface and deliver good electrochemical performance in both symmetric and full cells. The discovery of this gc‐Li3.2P0.8Sn0.2S4 superionic conductor enriches the choice of advanced SSEs and accelerates the commercialization of ASSLMBs.
Recent Developments in Z‐Selective Olefin Metathesis Reactions by Molybdenum, Tungsten, Ruthenium, and Vanadium Catalysts

Published: January 2021

AbstractThis review article summarizes reports for Z‐selective olefin metathesis reactions by molybdenum, tungsten, ruthenium, and vanadium catalysts. It is clearly demonstrated that the ligand modifications play essential roles in achieving the stereospecific olefin metathesis reactions. In particular, Mo‐ and W‐alkylidene based complex catalysts having pyrrolide‐aryloxide [or bis(aryloxide)] were highly effective in the efficient enantioselective ring opening/cross‐metathesis (EROCM), cross metathesis (CM), homodimerization, ring‐opening metathesis polymerization (ROMP), and in ring closing metathesis (RCM) with high Z‐ selectivities (∼>98%). Ruthenium‐carbene catalysts having cycloadamantyl, catechothiolate, phenolate and thiophenolate ligands display pronounced Z‐selectivity (>98%) in efficient CM, ROCM, AROCM, RCM, ROMP reactions. Halogenated (arylimido)‐alkoxo vanadium‐alkylidenes were thermally robust and effective for efficient highly cis‐specific ROMP of cyclic olefins to afford end‐functionalized ring‐opened polymers.magnified image
Current trends and key considerations in the clinical translation of targeted fluorescent probes for intraoperative navigation
Authors: Liu Renfa , Xu Yunxue , Xu Kun , Dai Zhifei 
Published: January 2021

AbstractThe rapid development of fluorescence imaging for intraoperative navigation has spurred further development of targeted fluorescent probes in the past decade. Only a few nontargeted dyes, including indocyanine green and methylene blue, are currently applied for fluorescence guided surgery in the clinic. While no targeted fluorescent probes have been approved for the clinic, a number of them have entered clinical trials. These probes have emission wavelengths in the visible and near infrared (NIR)‐I (700‐900 nm) range. Among them, activatable probes and nanoprobes have generated special interest. Compared with NIR‐I fluorescent probes, NIR‐II (1000‐1700 nm) fluorescent probes exhibit better intravital performance in terms of increased penetration depths, reduced tissue autofluorescence, and higher signal‐to‐background ratios. However, more challenges are expected before the successful translation of NIR‐II probes from bench to bedside. This review provides a brief overview of targeted fluorescent probes under clinical evaluation and recent achievements in the field of NIR‐II fluorescence imaging. In addition, we outline key considerations concerning the design of fluorescent probes for clinical translation.

Published: January 2021

AbstractHydrogels are polymeric materials widely used in medicine due to their similarity with the biological components of the body. Hydrogels are biocompatible materials that have the potential to promote cell proliferation and tissue support because of their hydrophilic nature, porous structure, and elastic mechanical properties. In this work, we demonstrate the microwave‐assisted synthesis of three molecular weight varieties of poly(ethylene glycol) dimethacrylate (PEGDMA) with different mechanical and thermal properties and the rapid photo of them using 1‐hydroxy‐cyclohexyl‐phenyl‐ketone (Irgacure 184) as UV photoinitiator. The effects of the poly(ethylene glycol) molecular weight and degree of acrylation on swelling, mechanical, and rheological properties of hydrogels were investigated. The biodegradability of the PEGDMA hydrogels, as well as the ability to grow and proliferate cells, was examined for its viability as a scaffold in tissue engineering. Altogether, the biomaterial hydrogel properties open the way for applications in the field of regenerative medicine for functional scaffolds and tissues.

AbstractIn archaeo‐geophysical investigations, the accuracy and resolution of the generated geophysical models are crucial parameters for excavation decision. Therefore, the combined use of different geophysical data sets is necessary to improve the interpretability of archaeological ruins, particularly in case of low physical contrast objects. The present study's objective is to validate the outputs of integrated ground penetrating radar (GPR) and electrical resistivity tomography (ERT) surveys in Tanis, which is considered one of the most important archaeological sites in the Nile Delta, Egypt. The GPR survey was carried out along an area of 24 × 31.5 m with profile interval of 0.5 m in two orthogonal directions using 100, 200 and 600 MHz shielded antenna. Moreover, nine ERT profiles were performed along the same GPR lines for comparison and integration using Wenner‐beta (WB) and dipole–dipole (DD) arrays with 1 m electrode spacing and 3 m profile spacing. In addition, the ERT measurements were executed by implementing two tie lines of the same length, electrode spacing and electrode arrays to reduce the effect of banding or directional bias. The processed 2D GPR and ERT profiles have illustrated series of mud‐brick walls within the top 2 m in silt–clay background which is underlined by the turtle‐back of Sand Island. In such conditions, the mud‐brick walls in conductive soils with complex spatial distributions have produced tricky and difficult anomalies to be interpreted using only 2D data sets. To overcome this challenging case, the GPR orthogonal profiles were collated in 3D domain, while the ERT profiles were gathered and inverted using 3D robust inversion algorithm and validated with an identified mud‐brick wall. Therefore, the created 3D visualizations demonstrated the efficiency of the joint use of the ERT and GPR surveys as an enhanced mapping tool for buried archaeological ruins and can be used at similar archaeological sites all over the world.

Published: January 2021

AbstractThis paper proposes high‐degree cubature Kalman filter for nonlinear systems with missing measurements. We derive out the explicit formulas for the prediction and update in the filtering. To fulfill the numerical computation, especially the numerical integrals, of these formulas, the fifth‐degree spherical‐radial cubature rule is adopted to give a high‐degree cubature Kalman filtering algorithm. Through numerical example, it is shown that the fifth‐degree cubature Kalman filter has better precision and stability than the extended Kalman filter, the unscented Kalman filter, and the fifth‐degree unscented Kalman filter.
