Abstract
OBJECTIVE. This pilot study is the first to examine the effects of an occupational therapist–led African drumming group on mental well-being among adult psychiatric inpatients with mood disorders.
METHOD. We used a quasi-experimental, uncontrolled, one-group, pretest–posttest design. We collected data for six different drumming groups (N = 13) using the Stellenbosch Mood Scale, the Primary Health Questionnaire–9, the Generalized Anxiety Disorder–7 scale, and the Enjoyment of Interaction Scale.
RESULTS. Participants significantly improved on all six domains of the Stellenbosch Mood Scale, with a large clinical effect. Participants with higher self-reported anxiety and depression benefited the most. According to the Enjoyment of Interaction Scale results, all the participants enjoyed the drumming “a great deal.”
CONCLUSION. Our positive findings suggest that drumming may be an effective intervention for adults with acute mood disorders. We recommend further research that uses a control intervention.

Published: July 2018

Objective: At an academic health sciences library serving a wide variety of disciplines, studying library users’ technology use provides necessary information on intersection points for library services. Administering a similar survey annually for five years generated a holistic view of users’ technology needs and preferences over time.Methods: From 2012 to 2016, the University of Florida Health Science Center Library (HSCL) annually administered a sixteen-to-twenty question survey addressing health sciences users’ technology awareness and use and their interest in using technology to engage with the library and its services. The survey was distributed throughout the HSC via email invitation from liaison librarians to their colleges and departments and advertisement on the HSCL home page.Results: Smartphone ownership among survey respondents was nearly universal, and a majority of respondents also owned a tablet. While respondents were likely to check library hours, use medical apps, and use library electronic resources from their mobile devices, they were unlikely to friend or follow the library on Facebook or Twitter or send a call number from the catalog. Respondents were more likely to have used EndNote than any other citation management tool, but over 50% of respondents had never used each tool or never heard of it.Conclusions: Annual review of survey results has allowed librarians to identify users’ needs and interests, leading to incremental changes in services offered. Reviewing the aggregate data allowed strategic consideration of how technology impacts library interactions with users, with implications toward library marketing, training, and service development. This article has been approved for the Medical Library Association’s Independent Reading Program.

After the Riot? Rancière, Hamilton, and Radical Politics
Authors: Piper Laurence 
Published: July 2018

Abstract
In recent years, political forces from the Occupy movement in North America to the #FeesMustFall student protest in South Africa have attempted to disrupt the political order in the name of democratic equality. Inspired by radical theorists like Rancière, this politics promises a model of social change through the combination of the disruption of institutions and the reinvention of daily life and political subjectivities. I argue that this radical politics comes with significant limits if it ignores the requirement to build more inclusive policies and new institutions too. This is because disruption alone may extend exclusion by prompting more elite coercion and popular backlash. This claim is illustrated through the example of the #FeesMustFall movement. What is needed instead is a radical politics that also includes a clear theoretical focus on policy and institutional change, such as is contained in Hamilton's account of freedom as power through representation.

Objective
Gastric cancer (GC) is the fourth most common cause of cancer-related deaths in the world. In the current study, we aim to identify the hub genes and uncover the molecular mechanisms of GC.

Methods
The expression profiles of the genes and the miRNAs were extracted from the Gene Expression Omnibus database. The identification of the differentially expressed genes (DEGs), including miRNAs, was performed by the GEO2R. Database for Annotation, Visualization and Integrated Discovery was used to perform GO and KEGG pathway enrichment analysis. The protein–protein interaction (PPI) network and miRNA-gene network were constructed using Cytoscape software. The hub genes were identified by the Molecular Complex Detection (MCODE) plugin, the CytoHubba plugin and miRNA-gene network. Then, the identified genes were verified by Kaplan–Meier plotter database and quantitative real-time PCR (qRT-PCR) in GC tissue samples.

Results
A total of three mRNA expression profiles (GSE13911, GSE79973 and GSE19826) were downloaded from the Gene Expression Omnibus (GEO) database, including 69, 20 and 27cases separately. A total of 120 overlapped upregulated genes and 246 downregulated genes were identified. The majority of the DEGs were enriched in extracellular matrix organization, collagen catabolic process, collagen fibril organization and cell adhesion. In addition, three KEGG pathways were significantly enriched, including ECM-receptor interaction, protein digestion and absorption, and the focal adhesion pathways. In the PPI network, five significant modules were detected, while the genes in the modules were mainly involved in the ECM-receptor interaction and focal adhesion pathways. By combining the results of MCODE, CytoHubba and miRNA-gene network, a total of six hub genes including COL1A2, COL1A1, COL4A1, COL5A2, THBS2 and ITGA5 were chosen. The Kaplan–Meier plotter database confirmed that higher expression levels of these genes were related to lower overall survival, except for COL5A2. Experimental validation showed that the rest of the five genes had the same expression trend as predicted.

Conclusion
In conclusion, COL1A2, COL1A1, COL4A1, THBS2 and ITGA5 may be potential biomarkers and therapeutic targets for GC. Moreover, ECM-receptor interaction and focal adhesion pathways play significant roles in the progression of GC.

AbstractThis work demonstrates the efficacy of voxel‐based 90Y microsphere dosimetry utilizing post‐therapy SPECT/CT imaging and applies it to the prediction of treatment response for the management of patients with hepatocellular carcinoma (HCC). A 90Y microsphere dosimetry navigator (RapidSphere) within a commercial platform (Velocity, Varian Medical Systems) was demonstrated for three microsphere cases that were imaged using optimized bremsstrahlung SPECT/CT. For each case, the 90Y SPECT/CT was registered to follow‐up diagnostic MR/CT using deformable image registration. The voxel‐based dose distribution was computed using the local deposition method with known injected activity. The system allowed the visualization of the isodose distributions on any of the registered image datasets and the calculation of dose‐volume histograms (DVHs). The dosimetric analysis illustrated high local doses that are characteristic of blood‐flow directed brachytherapy. In the first case, the HCC mass demonstrated a complete response to treatment indicated by a necrotic region in follow‐up MR imaging. This result was dosimetrically predicted since the gross tumor volume (GTV) was well covered by the prescription isodose volume (V150 Gy = 85%). The second case illustrated a partial response to treatment which was characterized by incomplete necrosis of an HCC mass and a remaining area of solid enhancement in follow‐up MR imaging. This result was predicted by dosimetric analysis because the GTV demonstrated incomplete coverage by the prescription isodose volume (V470 Gy = 18%). The third case demonstrated extrahepatic activity. The dosimetry indicated that the prescription (125 Gy) isodose region extended outside of the liver into the duodenum (178 Gy maximum dose). This was predictive of toxicity as the patient later developed a duodenal ulcer. The ability to predict outcomes and complications using deformable image registration, calculated isodose distributions, and DVHs, points to the clinical utility of patient‐specific dose calculations for 90Y radioembolization treatment planning.

AbstractA Ni‐catalyzed decarboxylative cross‐coupling of potassium polyfluorobenzoates with unactivated phenol and phenylmethanol derivatives is described. This novel transformation provides a practical and efficient protocol towards the synthesis of important polyfluorobiaryls and polyfluorinated diarylmethanes, and greatly enlarges the range of electrophiles utilized in decarboxylative coupling. Remarkably, preliminary mechanistic studies indicated the essential role of Zn(OAc)2 might lie in the enhancement of decarboxylation step.magnified image
Photoexcitation in Solids: First‐Principles Quantum Simulations by Real‐Time TDDFT
Authors: Lian Chao , Guan Mengxue , Hu Shiqi , Zhang Jin , Meng Sheng 
Published: July 2018

AbstractAn efficient and state‐of‐the‐art real‐time time‐dependent density functional theory (rt‐TDDFT) method is presented, as implemented in the time‐dependent ab initio package (TDAP), which aims at performing accurate simulations of the interaction between laser fields and solid‐state materials. The combination of length‐gauge and velocity‐gauge electromagnetic field has extended the diversity of materials under consideration, ranging from low dimensional systems to periodic solids. Meanwhile, by employing a local basis presentation, systems of a large size are simulated for long electronic propagation time, with moderate computational cost while maintaining a relatively high accuracy. Non‐perturbative phenomena in materials under a strong laser field and linear responses in a weak field can be simulated, either in the presence of ionic motions or not. Several quintessential works are introduced as examples for applications of this approach, including photoabsorption properties of armchair graphene nanoribbon, hole‐transfer ultrafast dynamics between MoS2/WS2 interlayer heterojunction, laser‐induced nonthermal melting of silicon, and high harmonic generation in monolayer MoS2. The method demonstrates great potential for studying ultrafast electron‐nuclear dynamics and nonequilibrium phenomena in a wide range of quantum systems.
Tin Oxide as a Protective Heterojunction with Silicon for Efficient Photoelectrochemical Water Oxidation in Strongly Acidic or Alkaline Electrolytes

Published: July 2018

AbstractPhotoelectrodes without a p–n junction are often limited in efficiency by charge recombination at semiconductor surfaces and slow charge transfer to electrocatalysts. This study reports that tin oxide (SnOx) layers applied to n‐Si wafers after forming a thin chemically oxidized SiOx layer can passivate the Si surface while producing ≈620 mV photovoltage under 100 mW cm−2 of simulated sunlight. The SnOx layer makes ohmic contacts to Ni, Ir, or Pt films that act as precatalysts for the oxygen‐evolution reaction (OER) in 1.0 m KOH(aq) or 1.0 m H2SO4(aq). Ideal regenerative solar‐to‐O2(g) efficiencies of 4.1% and 3.7%, respectively, are obtained in 1.0 m KOH(aq) with Ni or in 1.0 m H2SO4(aq) with Pt/IrOx layers as OER catalysts. Stable photocurrents for >100 h are obtained for electrodes with patterned catalyst layers in both 1.0 m KOH(aq) and 1.0 m H2SO4(aq).

AbstractOrganic–inorganic hybrid perovskite solar cells (PSCs) are currently attracting significant interest owing to their promising outdoor performance. However, the ability of indoor light harvesting of the perovskites and corresponding device performance are rarely reported. Here, the potential of planar PSCs in harvesting indoor light for low‐power consumption devices is investigated. Ionic liquid of 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([BMIM]BF4) is employed as a modification layer of [6,6]‐phenyl‐C61‐butyric acid methyl ester) (PCBM) in the inverted PSCs. The incorporation of [BMIM]BF4 not only paves the interface contact between PCBM and electrode, but also facilitates the electron transport and extraction owing to the efficient passivation of the surface trap states. Moreover, [BMIM]BF4 with excellent thermal stability can act as a protective layer by preventing the erosion of moisture and oxygen into the perovskite layer. The resulting devices present a record indoor power conversion efficiency (PCE) of 35.20% under fluorescent lamps of 1000 lux, and an impressive PCE of 19.30% under 1 sun illumination. The finding in this work verifies the excellent indoor performance of PSCs to meet the requirements of eco‐friendly economy.

Published: July 2018

AbstractA new porous organic poly(triphenylimidazole), PTPI‐Me, was prepared through a Yamamoto self‐coupling reaction of 2,4,5‐tris‐(4‐bromophenyl)‐1‐methyl‐1H‐imidazole (TPI‐Me) in the presence of bis(1,5‐cyclooctadiene)nickel(0). The polymer was subsequently decorated with Pd nanoparticles (NPs) to afford a heterogeneous cyanation catalyst, Pd@PTPI‐Me. Pd NPs with an average diameter of 2.7 nm were grown within the PTPI‐Me framework, owing to the coordination of the imidazole rings to the Pd species. The resultant Pd@PTPI‐Me catalyst, with a Pd loading of 0.13 mmol g−1, exhibited superior catalytic activity for the cyanation of aryl iodides. More importantly, the heterogeneous catalyst was also readily recycled and displayed negligible deactivation after five cycles.
Boron Ester‐Catalyzed Amidation of Carboxylic Acids with Amines: Mechanistic Rationale by Computational Study
Authors: Jiang Yuan‐Ye , Hu Ben , Xu Zhong‐Yan , Zhang Rui‐Xue , Liu Tian‐Tian , Bi Siwei 
Published: July 2018

AbstractA novel boron ester‐catalyzed amidation reaction of carboxylic acids and amines with unprecedented functional group tolerance was recently reported. To gain deeper insights into this reaction, a computational study with density functional theory methods was performed in this manuscript. Calculations indicate that the amidation starts with the condensation of carboxylic acids with the boron ester catalyst. The resulting monoacyloxylated boron species further undergoes the carboxylic acid‐assisted nucleophilic addition with amines to generate the amide product and a monohydroxyboron species. The condensation of the carboxylic acid with the monohydroxyboron species with the assistance of an amine regenerates monoacyloxylated boron species to finish the catalytic cycle. The rate‐determining step is catalyst regeneration and the amine‐coordinated monohydroxyboron species is the resting state in the catalytic cycle. The present results are consistent with the previous NMR study and the observed reaction orders of catalyst and substrates; it is expected to benefit further reaction optimization.

AbstractThe development of effective bioanalytical methods for rapid, sensitive and specific detection of HOCl in vitro and in vivo plays a key role for better understanding the roles of this molecule in normal and diseased conditions, but remains challenging due to the highly reactive nature of HOCl and the complicated biological conditions. In this work, a new fluorescence probe, PQI, was developed for monitoring of the HOCl level in biological samples. PQI was easily synthesized by a one‐step condensation reaction. Upon addition of HOCl, significant changes in the absorption spectra and the color of the solution were noticed, facilitating the “naked eye” detection of HOCl in PBS buffer. The fluorescence of PQI was found to be significantly increased within a few seconds, leading to “OFF‐ON” fluorescence response towards HOCl. The sensing mechanism, oxidation of thioether by HOCl, was confirmed by HRMS titration analysis. PQI features a large Stokes shift, high sensitivity and selectivity, and rapid fluorescence response towards HOCl. Quantitative detection of HOCl in single live cells was demonstrated through fluorescence imaging and flow cytometry analysis. PQI was then successfully used in visualisation of HOCl in live zebrafish and nude mice.
Control Schemes for Autonomous Car‐following Systems with two Classical Compensators
Authors: Zhu Wen‐Xing , Zhang Li‐Dong 
Published: July 2018

AbstractIn this paper, we improve the dynamics of an autonomous car‐following system with two classical compensation methods: proportional‐differential (PD) and velocity feedback (VF) control methods. Based on an optimal velocity model, the system transfer function was derived and control block diagram was given with an open‐loop transfer function. Three theorems were proposed and proven with the use of small gain theorem. The analytical results show that two compensation factors play important roles in stabilizing the car‐following system. In the simulation, three dynamical models were derived in reverse from the closed‐loop transfer function and the numerical results show that, with increasing factors, the stability of car‐following was enhanced and traffic jams were eliminated. The analytical results are supported by the numerical results.

AbstractA novel and straightforward synthesis of highly substituted isoquinoline‐5,8‐dione fused tricyclic pyrazoles is reported. The key step of the synthetic sequence is a regioselective, Ag2CO3 promoted, 1,3‐dipolar cycloaddition of C‐heteroaryl‐N‐aryl nitrilimines and substituted isoquinoline‐5,8‐diones. The broad functional group tolerability and mild reaction conditions were found to be suitable for the preparation of a small library of compounds. These scaffolds were designed to interact with multiple biological residues, and two of them, after brief synthetic elaborations, were analyzed by molecular docking studies as potential anticancer drugs. In vitro studies confirmed the potent anticancer effects, showing promising IC50 values as low as 2.5 μm against three different glioblastoma cell lines. Their cytotoxic activity was finally positively correlated to their ability to inhibit PI3K/mTOR kinases, which are responsible for the regulation of diverse cellular processes in human cancer cells.
