Published: April 2016

Schizophrenia (SCZ) is a complex and severe mental disorder with highly heritability (80%). Several large genome‐wide association studies have identified that the transcription factor 4 (TCF4) polymorphisms were strongly associated with SCZ. Therefore, the present study was to replicate the potential relationships between the TCF4 polymorphisms and SCZ. Furthermore, the study also investigated whether other variants were associated with SCZ in the Han Chinese. We conducted a case‐control study including 499 patients and 500 healthy controls. Five SNPs were successfully genotyped and evaluated the association with SCZ by using χ2 test and genetic model analysis. We found that the genotype “AG” of rs9320010 and “GA” of rs7235757 decreased SCZ risk (OR = 0.70, 95%CI = 0.50–0.99, P = 0.041; OR = 0.69, 95%CI = 0.49–0.97, P = 0.034, respectively). In the genetic model analysis, we also observed that the allele “A” of rs9320010 and “G” of rs7235757 were inversely related with the risk of SCZ in the dominant model (OR = 0.72, 95%CI = 0.52–0.98, P = 0.039; OR = 0.69, 95%CI = 0.50–0.96, P = 0.025, respectively). Further interaction and stratification analysis suggested that rs1452787 was notably correlated with increased SCZ risk in males (OR = 2.77, 95%CI = 1.43–5.35, P = 0.002). Our study indicated that rs9320010, rs7235757, and rs1452787 were prominently associated with SCZ. Further studies are required to verify our findings and focus on determining the biological functions of the SNPs. © 2016 Wiley Periodicals, Inc.

Published: April 2016

Two‐dimensional (2D) transition‐metal dichalcogenides (TMDs) have drawn much attention due to their unique physical and chemical properties. Using TMDs as templates for the generation of 2D sandwich‐like materials with remarkable properties still remains a great challenge due to their poor solvent processability. Herein, MoS2‐coupled sandwich‐like conjugated microporous polymers (M‐CMPs) with high specific surface area were successfully developed by using functionalized MoS2 nanosheets as template. As‐prepared M‐CMPs were further used as precursors for preparation of MoS2‐embedded nitrogen‐doped porous carbon nanosheets, which were revealed as novel electrocatalysts for oxygen reduction reaction with mainly four‐electron transfer mechanism and ultralow half‐wave potential in comparison with commercial Pt/C catalyst. Our strategy to core–shelled sandwich‐like hybrids paves a way for a new class of 2D hybrids for energy conversion and storage.
The Simplest Amino‐borane H2B=NH2 Trapped on a Rhodium Dimer: Pre‐Catalysts for Amine–Borane Dehydropolymerization
Authors: Kumar Amit , Beattie Nicholas A. , Pike Sebastian D. , Macgregor Stuart A. , Weller Andrew S.
Published: April 2016

The μ‐amino–borane complexes [Rh2(LR)2(μ‐H)(μ‐H2B=NHR′)][BArF4] (LR=R2P(CH2)3PR2; R=Ph, iPr; R′=H, Me) form by addition of H3B⋅NMeR′H2 to [Rh(LR)(η6‐C6H5F)][BArF4]. DFT calculations demonstrate that the amino–borane interacts with the Rh centers through strong Rh‐H and Rh‐B interactions. Mechanistic investigations show that these dimers can form by a boronium‐mediated route, and are pre‐catalysts for amine‐borane dehydropolymerization, suggesting a possible role for bimetallic motifs in catalysis.
MALDI‐MS Patterning of Caspase Activities and Its Application in the Assessment of Drug Resistance
Authors: Hu Junjie , Liu Fei , Ju Huangxian
Published: April 2016

Mass spectrometry (MS) has been widely used for enzyme activity assays. Herein, we propose a MALDI‐MS patterning strategy for the convenient visual presentation of multiple enzyme activities with an easy‐to‐prepare chip. The array‐based caspase‐activity patterned chip (Casp‐PC) is fabricated by hydrophobically assembling different phospholipid‐tagged peptide substrates on a modified ITO slide. The advantages of amphipathic phospholipids lead to high‐quality mass spectra for imaging analysis. Upon the respective cleavage of these substrates by different caspases, such as caspase‐1, ‐2, ‐3, and ‐8, to produce a mass shift, the enzyme activities can be directly evaluated by MALDI‐MS patterning by m/z‐dependent imaging of the cleavage products. The ability to identify drug‐sensitive/resistant cancer cells and assess the curative effects of anticancer drugs is demonstrated, indicating the applicability of the method and the designed chip.
Synthesis of Biaryls through Nickel‐Catalyzed Suzuki–Miyaura Coupling of Amides by Carbon–Nitrogen Bond Cleavage
Authors: Shi Shicheng , Meng Guangrong , Szostak Michal
Published: April 2016

The first Ni‐catalyzed Suzuki–Miyaura coupling of amides for the synthesis of widely occurring biaryl compounds through N−C amide bond activation is reported. The reaction tolerates a wide range of electron‐withdrawing, electron‐neutral, and electron‐donating substituents on both coupling partners. The reaction constitutes the first example of the Ni‐catalyzed generation of aryl electrophiles from bench‐stable amides with potential applications for a broad range of organometallic reactions.
Na2BaMQ4 (M=Ge, Sn; Q=S, Se): Infrared Nonlinear Optical Materials with Excellent Performances and that Undergo Structural Transformations
Authors: Wu Kui , Yang Zhihua , Pan Shilie
Published: April 2016

Infrared nonlinear optical (IR NLO) materials with excellent performances are particularly important in laser technology. However, to design and synthesize an efficient IR NLO material with a balance between the optical band gap and the NLO coefficient is still a huge challenge. With this in mind, four new IR NLO materials Na2BaSnS4, Na2BaSnSe4, Na2BaGeS4, and Na2BaGeSe4 were successfully designed and synthesized. The compounds exhibit excellent properties with a suitable balance of band gap and NLO coefficient measured for Na2BaSnS4 (3.27 eV and about 17×KDP, that is, about 17 times that of KH2PO4 (KDP)) and Na2BaGeS4 (3.7 eV and about 10×KDP), demonstrating that the systems satisfy the key requirements as promising IR NLO candidates. Remarkably, the new compounds also undergo a novel structural transformation from tetragonal to trigonal systems, the first time that this has been reported for quaternary metal chalcogenides.
A Phytochrome Sensory Domain Permits Receptor Activation by Red Light

Published: April 2016

Optogenetics and photopharmacology enable the spatio‐temporal control of cell and animal behavior by light. Although red light offers deep‐tissue penetration and minimal phototoxicity, very few red‐light‐sensitive optogenetic methods are currently available. We have now developed a red‐light‐induced homodimerization domain. We first showed that an optimized sensory domain of the cyanobacterial phytochrome 1 can be expressed robustly and without cytotoxicity in human cells. We then applied this domain to induce the dimerization of two receptor tyrosine kinases—the fibroblast growth factor receptor 1 and the neurotrophin receptor trkB. This new optogenetic method was then used to activate the MAPK/ERK pathway non‐invasively in mammalian tissue and in multicolor cell‐signaling experiments. The light‐controlled dimerizer and red‐light‐activated receptor tyrosine kinases will prove useful to regulate a variety of cellular processes with light.

Authors: Ochiai Tatsumi , Franz Daniel , Wu Xiao‐Nan , Irran Elisabeth , Inoue Shigeyoshi
Published: April 2016

The lithium bis(imino)stannylenoid (NIPr)2Sn(Li)Cl (1; NIPr=bis(2,6‐diisopropylphenyl)imidazolin‐2‐imino) was prepared by the reaction of LiNIPr with 0.5 equiv of SnCl2⋅diox (diox=1,4‐dioxane) and the ambiphilic character of the compound was demonstrated by investigations into its reactivity. Treatment of 1 with I2 or MeI yielded the oxidative addition products (NIPr)2SnI2 and (NIPr)2Sn(Me)I, respectively. In contrast, the reaction of 1 with one equivalent of Me3SiCl resulted in the formation of Me3SiNIPr and the chlorostannylene dimer [NIPrSnCl]2. Moreover, the substitution reaction of compound 1 with MeLi led to the formation of the methyl‐substituted stannate (NIPr)2Sn(Li)Me.
Pentavalent Lanthanide Compounds: Formation and Characterization of Praseodymium(V) Oxides
Authors: Zhang Qingnan , Hu Shu‐Xian , Qu Hui , Su Jing , Wang Guanjun , Lu Jun‐Bo , Chen Mohua , Zhou Mingfei , Li Jun
Published: April 2016

The chemistry of lanthanides (Ln=La–Lu) is dominated by the low‐valent +3 or +2 oxidation state because of the chemical inertness of the valence 4f electrons. The highest known oxidation state of the whole lanthanide series is +4 for Ce, Pr, Nd, Tb, and Dy. We report the formation of the lanthanide oxide species PrO4 and PrO2+ complexes in the gas phase and in a solid noble‐gas matrix. Combined infrared spectroscopic and advanced quantum chemistry studies show that these species have the unprecedented PrV oxidation state, thus demonstrating that the pentavalent state is viable for lanthanide elements in a suitable coordination environment.
Interface Engineering of MoS2/Ni3S2 Heterostructures for Highly Enhanced Electrochemical Overall‐Water‐Splitting Activity
Authors: Zhang Jian , Wang Tao , Pohl Darius , Rellinghaus Bernd , Dong Renhao , Liu Shaohua , Zhuang Xiaodong , Feng Xinliang
Published: April 2016

To achieve sustainable production of H2 fuel through water splitting, low‐cost electrocatalysts for the hydrogen‐evolution reaction (HER) and the oxygen‐evolution reaction (OER) are required to replace Pt and IrO2 catalysts. Herein, for the first time, we present the interface engineering of novel MoS2/Ni3S2 heterostructures, in which abundant interfaces are formed. For OER, such MoS2/Ni3S2 heterostructures show an extremely low overpotential of ca. 218 mV at 10 mA cm−2, which is superior to that of the state‐of‐the‐art OER electrocatalysts. Using MoS2/Ni3S2 heterostructures as bifunctional electrocatalysts, an alkali electrolyzer delivers a current density of 10 mA cm−2 at a very low cell voltage of ca. 1.56 V. In combination with DFT calculations, this study demonstrates that the constructed interfaces synergistically favor the chemisorption of hydrogen and oxygen‐containing intermediates, thus accelerating the overall electrochemical water splitting.
Synthesis of a new iron–sulfur cluster compound and its photocatalytic H2 evolution activity through visible light irradiation
Authors: Wang Xiao‐Bo , Zheng Hui‐Qin , Rao Heng , Yao Hong‐Chang , Fan Yao‐Ting , Hou Hong‐Wei
Published: April 2016

A new iron–sulfur cluster compound, namely [(μ‐BNT)Fe2(CO)6] (A; BNT = (R)‐1,1′‐binaphthalene‐2,2′‐dithiol), was synthesized by self‐assembly of BNT with [Fe3(CO)12] and characterized using 1H NMR, 13C NMR, infrared spectra and elemental analysis. The H2 evolution activity of A was evaluated in a constructed homogeneous photocatalytic system by combining A as catalyst, xanthene dyes as photosensitizer and triethylamine as sacrificial reagent, to give efficient H2 generation under visible‐light irradiation (λ > 420 nm). The maximum H2 evolution of 404 turnovers (versus catalyst) was recorded under optimal conditions in CH3CN–H2O (1:1, v/v) after 4 h irradiation. The mechanism of H2 evolution is briefly discussed using fluorescence spectra and electrochemical analysis. Copyright © 2016 John Wiley & Sons, Ltd.
Anisotropy of the elastic modulus for hybrid composites reinforced by short fibers and particles with respect to material porosity
Authors: Dai Hong‐Liang , Mei Chao , Rao Yan‐Ni
Published: April 2016

Hybrid composites reinforced by short fibers and particles (HCRSFPs) have been widely used in many fields, and more and more scholars are paying attention to hybrid composites. In this study, the elastic moduli of HCRSFPs in arbitrarily chosen directions were investigated with respect to their porosities. A material model was built with the assumption of a compound of particles and polymer matrix containing voids as an effective matrix, and the HCRSFPs were treated as the compound of short fibers and the effective matrix. With consideration of the three‐dimensional spatial orientation distribution and the length distribution of the short fibers, the laminate analog approach and the Halpin–Tsai model were used to predict the elastic moduli of the HCRSFPs. Numerical examples and analyses showed that the fiber orientation distribution, reinforcement volume fraction, and porosity had great effects on the elastic moduli of the HCRSFPs. © 2016 Wiley Periodicals, Inc.

Influence of process parameters on the structure formation of man‐made cellulosic fibers from ionic liquid solution
Authors: Michud Anne , Hummel Michael , Sixta Herbert
Published: April 2016

The influence of dry‐jet wet spinning parameters on the production of man‐made cellulosic fibers from 13 wt % cellulose/1,5‐diazabicyclo[4.3.0]non‐5‐ene acetate solutions was investigated. The spinneret nozzle diameter, extrusion velocity, draw ratio, and coagulation bath temperature were the studied parameters. The production of highly oriented fibers was favored by selecting higher extrusion velocity and lower spinneret diameter. A spinneret size of 100 µm and a draw ratio of 6 were sufficient to highly orient the cellulose macromolecules and achieve tenacities above 40 cN/tex (600 MPa). Total orientation assessed via birefringence measurement, tenacity, and Young's modulus values reached a plateau at a draw of 6 and no further development in properties was observed. A temperature of the aqueous coagulation bath of 15 °C slightly promoted greater orientation of the fibers by hampering structural changes of the cellulose macromolecules in the nascent solid fibers. Furthermore, the determination of the elongational viscosity of the liquid thread via the measurement of radial force tensor was tested and showed promising results. © 2016 Wiley Periodicals, Inc. J.

Development of biodegradable polymeric nanoparticles for encapsulation, delivery, and improved antifungal performance of natamycin
Authors: Bouaoud Clotilde , Xu Sala , Mendes Eduardo , Lebouille Jérôme G. J. L. , De Braal Henriette E. A. , Meesters Gabriel M. H.
Published: April 2016

The aim of this study was to evaluate biodegradable poly(lactide‐co‐glycolide) nanoparticles as potential nano‐delivery systems for the food antifungal compound natamycin. Natamycin‐loaded nanoparticles were prepared at various ratios polymer/antifungal by the nanoprecipitation technique, resulting in nano‐size particles (80–120 nm) with a narrow distribution and a spherical morphology. Complexation of natamycin with PLGA and active participation to the nanoparticle formation were evidenced by a mean diameter reduction of 10–30 nm, although encapsulation levels remained low due to the zwitterionic and partially hydrophilic nature of natamycin. Physical state analyses highlighted the presence of natamycin in an amorphous or molecularly dispersed state within the polymeric matrix. This translates into high availability of free antifungal molecules reflected in burst release and fast in vitro release kinetics rates as well as enhanced antifungal performance against the model food yeast Saccharomyces cerevisiae, offering a potential benefit for antifungal protection compared with the commercially available natamycin products. © 2016 Wiley Periodicals, Inc.

Scaling and Accommodation of Jaw Adductor Muscles in Canidae
Authors: Penrose Fay , Kemp Graham J. , Jeffery Nathan
Published: April 2016

The masticatory apparatus amongst closely related carnivoran species raises intriguing questions about the interplay between allometry, function, and phylogeny in defining interspecific variations of cranial morphology. Here we describe the gross structure of the jaw adductor muscles of several species of canid, and then examine how the muscles are scaled across the range of body sizes, phylogenies, and trophic groups. We also consider how the muscles are accommodated on the skull, and how this is influenced by differences of endocranial size. Data were collected for a suite of morphological metrics, including body mass, endocranial volume, and muscle masses and we used geometric morphometric shape analysis to reveal associated form changes. We find that all jaw adductor muscles scale isometrically against body mass, regardless of phylogeny or trophic group, but that endocranial volume scales with negative allometry against body mass. These findings suggest that head shape is partly influenced by the need to house isometrically scaling muscles on a neurocranium scaling with negative allometry. Principal component analysis suggests that skull shape changes, such as the relatively wide zygomatic arches and large sagittal crests seen in species with higher body masses, allow the skull to accommodate a relative enlargement of the jaw adductors compared with the endocranium.

Toward multiviewpoint ontology construction by collaboration of non‐experts and crowdsourcing: The case of the effect of diet on health
Authors: Zhitomirsky‐Geffet Maayan , Erez Eden S. , Judit Bar‐Ilan
Published: April 2016

Domain experts are skilled in buliding a narrow ontology that reflects their subfield of expertise based on their work experience and personal beliefs. We call this type of ontology a single‐viewpoint ontology. There can be a variety of such single viewpoint ontologies that represent a wide spectrum of subfields and expert opinions on the domain. However, to have a complete formal vocabulary for the domain they need to be linked and unified into a multiviewpoint model while having the subjective viewpoint statements marked and distinguished from the objectively true statements. In this study, we propose and implement a two‐phase methodology for multiviewpoint ontology construction by nonexpert users. The proposed methodology was implemented for the domain of the effect of diet on health. A large‐scale crowdsourcing experiment was conducted with about 750 ontological statements to determine whether each of these statements is objectively true, viewpoint, or erroneous. Typically, in crowdsourcing experiments the workers are asked for their personal opinions on the given subject. However, in our case their ability to objectively assess others' opinions was examined as well. Our results show substantially higher accuracy in classification for the objective assessment approach compared to the results based on personal opinions.

Published: April 2016

The effect of vitamin D3 in oral solution (VD3) and vitamin D3‐loaded nanocapsules (NC‐VD3) was analysed in animals with complete Freund's adjuvant (CFA) induced arthritis (AR). For this purpose, we evaluated scores for arthritis, thermal hyperalgesia and paw oedema, as well as histological analyses and measurements of the activity of the ectonucleoside triphosphate diphosphohydrolase (E‐NTPDase) and ecto‐adenosine deaminase (E‐ADA) enzymes in rat lymphocytes. Haematological and biochemical parameters were also determined. The doses administered were 120 UI/day of VD3 and 15.84 UI/day of NC‐VD3. Fifteen days after the induction of AR, the groups were treated for 15 days with vitamin D3. The results demonstrated that VD3 was able to reduce arthritis scores, thermal hyperalgesia and paw oedema in rats with CFA‐induced arthritis. However, treatment with NC‐VD3 did not reduce arthritis scores. The histological analyses showed that both formulations were able to reduce the inflammatory changes induced by CFA. The activity of E‐NTPDase in rat lymphocytes was higher in the AR compared with the control group, while the activity of E‐ADA was lower. This effect was reversed after the 15‐day treatment. Data from this study indicates that both forms of vitamin D3 seem to contribute to decreasing the inflammatory process induced by CFA, possibly altering the activities of ectoenzymes.

Significance of the Study

The effects promoted by both formulations of vitamin D3, either in oral solution or nanoencapsulated form, strongly suggests the softening of the inflammatory process induced by complete Freund's adjuvant (CFA), possibly altering the E‐NTPDase and E‐ADA activities. However, it is known that vitamin D has a beneficial effect on the modulation of the immune system components responsible for the inflammatory process. Moreover, the establishment of responses to treatment with vitamin D3 may provide an alternative for inhibiting the proinflammatory response, assisting in our understanding of the immunopathology of this disease and possibly improving the signs and symptoms that hinder the quality of life of patients with rheumatoid arthritis.

Highlights:

Evaluation of the effects on the E‐NTPDase and E‐ADA activities in an animal model of induced arthritis.

Two formulations of vitamin D3 were used: form oral solution and nanoencapsulated.

Vitamin D3 seems to contribute to the inflammatory process induced by CFA.

Vitamin D3 possibly alters the E‐NTPDase and E‐ADA activities.

Vitamin D3 may be an alternative supplementary treatment for chronic arthritis.
Family intervention in a prison environment: A systematic literature review
Authors: Roberts Anna , Onwumere Juliana , Forrester Andrew , Huddy Vyv , Byrne Majella , Campbell Catherine , Jarrett Manuela , Phillip Patricia , Valmaggia Lucia
Published: April 2016

Background

The prison population in England and Wales is approximately 85,000, and elevated rates of mental health difficulties have been reported among the prisoners. Despite frequent recommendations for family interventions to optimise prisoner outcomes, the evidence for its use and impact in prison remain unclear.

Aim

The aim of the study is to conduct a systematic review of published literature on family interventions in prisons.

Methods

Embase, PsychINFO and Medline were searched using terms for family interventions and for prisoners or young offenders. No limit was imposed on study design, but, for inclusion, we required that papers were written in English and published in peer‐reviewed journals.

Results

Nine hundred eighty‐three titles were retrieved. Twenty‐two met criteria for inclusion. Three were case studies, 12 were descriptive, 6 were quasi‐experimental and one was a randomised controlled trial. Interventions and study methods were too heterogeneous for meta‐analysis. All studies gave positive conclusions about family interventions, but empirical data on effectiveness were slight.

Conclusions

Consistency in findings across the wide‐ranging studies suggested that family therapies may indeed be helpful for prisoners and their families, so further research is warranted. The fact that a randomised controlled trial proved feasible should encourage researchers to seek more robust data and to determine which form of intervention is effective and in which circumstances. It would also be useful to develop an improved understanding of mechanisms of change. Copyright © 2016 John Wiley & Sons, Ltd.
