Authors: Gao Zhiqiu , Tong Bing , Horton Robert , Mamtimin Ali , Li Yubin , Wang Linlin 
Published: August 2017

AbstractSurface soil temperatures impact land‐atmosphere interactions in desert environments. Soil apparent thermal diffusivity (k) is a crucial physical parameter affecting soil temperature. Previous studies using the conduction‐convection algorithm reported k values of desert soils for only a few days. The main objective of this study is to determine the daily and monthly variations of desert k for a range of water contents over a 10 month period. The k values were estimated with a conduction‐convection algorithm using soil temperature measured at the 0.00 m and 0.20 m depths from 1 January to 11 October 2011 at the Tazhong station in the Taklimakan desert of China. Generally, the daily values of k ranged from 1.46  ×  10−7m2  s−1 to 5.88  × 10−7m2  s−1, and the 10 month average k value was 2.5(±0.8)  ×  10−7m2  s−1 for the 0.00 m to 0.20 m soil layer. The k values varied significantly with soil water content. The apparent convection parameter (W), which is the sum of the vertical gradient of k and apparent water flux density, was also determined. Comparison of the magnitudes of W and k gradients indicated that little water movement occurred during the dry months, some water infiltrated downward during the wet months, and some water moved upwards in response to evaporation following the wet months. These findings confirmed that the conduction‐convection algorithm described the general pattern of soil water movement. The presented daily and monthly values of k can be used as soil parameters when modeling land‐atmosphere interactions in the Taklimakan desert.

Published: August 2017

AbstractHighly efficient, yellow‐fluorescent organic light‐emitting diodes with a maximum external quantum efficiency exceeding 25.0% and extended lifetime are reported using iridium‐complex sensitizers doped in an exciplex host. Energy transfer processes reduce the lifetime of the exciplex and excitons on the Ir complexes and enable an excited state to exist in a conventional fluorescent emitter, thereby increasing device lifetime. The device stability depends on the location of the excited state.

Authors: Huang Yuan , Smith Kevin B. , Brown M. Kevin 
Published: August 2017

AbstractA method for the copper‐catalyzed borylacylation of activated alkenes is presented. The reaction involves borylcupration of the alkene, followed by capture of the generated alkyl–copper intermediate with an acid chloride. The reactions operated with low catalyst loading and generally occurre within 15 min at room temperature for a range of activated alkenes. In the case of vinyl arenes, enantioselective borylacylation was possible.

Published: August 2017

AbstractCarbon monoxide (CO) is one of the most important gaseous signal molecules in biological systems. However, the investigation of the functions of CO in living organisms is restricted by the lack of functional molecular tools. To address this critical challenge, we present herein the rational design, synthesis, and in vivo imaging studies of a powerful two‐photon excited near‐infrared fluorescent probe (1‐Ac) for endogenous CO monitoring. The advantageous features of the new probe include high stability, low background fluorescence, large fluorescence enhancement, high sensitivity, and two‐photon excitation with emission in the near‐infrared region. Significantly, these merits of the probe enable the tracking of endogenous CO in zebrafish embryos and mouse tissues for the first time.

Published: August 2017

AbstractThe redox chemistry of magnesium and its application in rechargeable Mg batteries has received increasing attention owing to the unique benefits of Mg metal electrodes, namely high reversibility without dendrite formation, low reduction potentials, and high specific capacities. The Mg/S couple is of particular interest owing to its high energy density and low cost. Previous reports have confirmed the feasibility of a rechargeable Mg/S battery; however, only limited cycling stability was achieved, and the complicated procedure for the preparation of the electrolytes has significantly compromised the benefits of Mg/S chemistry and hindered the development of Mg/S batteries. Herein, we report the development of the first rechargeable Mg/S battery with a MgTFSI2/MgCl2/DME electrolyte (DME=1,2‐dimethoxyethane, TFSI=bis(trifluoromethanesulfonyl)imide) and realize the best cycling stability among all reported Mg/S batteries by suppressing polysulfide dissolution. Mechanistic studies show that the battery works via S0/MgSx redox processes and that the large voltage hysteresis is mainly due to the Mg anode overpotential.
Peroxidyme‐Amplified Radical Chain Reaction (PARCR): Visible Detection of a Catalytic Reporter
Authors: Goertz John P. , White Ian M. 
Published: August 2017

AbstractPeroxidyme Amplified Radical Chain Reaction (PARCR), a novel enzyme‐free system that achieves exponential amplification of a visible signal, is presented. Typical enzyme‐free amplification systems that produce a visible readout suffer from long reaction times, low sensitivity, and narrow dynamic range. PARCR employs photocatalyzed nonlinear signal generation, enabling unprecedented one‐pot, naked‐eye detection of a catalytic reporter from 1 μm down to 100 pm. In this reaction, hemin‐binding peroxidase‐mimicking DNAzymes (“peroxidymes”) mediate the NADH‐driven oxidation of a colorless, nonfluorescent phenoxazine dye (Amplex Red) to a brightly colored, strongly fluorescent product (resorufin); illumination with green light initiates multiple radical‐forming positive‐feedback loops, rapidly producing visible levels of resorufin. Collectively, these results demonstrate the potential of PARCR as an easy‐to‐use readout for a range of detection schemes, including aptamer labels, hybridization assays, and nucleic acid amplification.

Published: August 2017

AbstractThe molar heat capacities of three tetrabutylammonium chloride (TBAC)‐based deep eutectic solvents (DESs) and their binary water mixtures were investigated in this work. Results showed a linear dependence of the molar heat capacity with temperature for all water compositions as well the pure components. The molar heat capacity decreased with increasing water composition for all systems. The TBAC : triethylene glycol system (DES2) showed the highest molar heat capacity (445.00–479.67 J mol−1 K−1) followed by the TBAC : ethylene glycol system (DES3); (288.34–312.59 J mol−1 K−1), while the TBAC : glycerol system (DES1) had the lowest molar heat capacity (281.20–310.85 J mol−1 K−1) among the three DES systems.The excess molar heat capacity, CPE, of the DES–water binary mixtures was determined. Results of CPE showed positive CPE for DES2 and negative CPE for DES3 for the entire range of water composition. DES1 showed a mix of positive and negative CPE values for the mixture. This behavior is explained as a result of the change in the intermolecular interaction between the DES–water molecules in the mixture compared with the DES–DES and water–water molecular interaction in the pure components. © 2017 Curtin University and John Wiley & Sons, Ltd.

Published: August 2017

ABSTRACTA gellan gum–Jeffamine superabsorbent hydrogel was obtained with different crosslink densities using different amounts of (1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide hydrochloride) and N‐hydroxysuccinimide. Infrared spectroscopy and thermal analysis confirm the crosslinking. A morphology analysis indicates denser structures for samples with higher crosslinking points. The swelling degree in high‐acyl gellan gum hydrogels was equivalent to 145 times their dry weight, and 77 times when low‐acyl gellan gum was used. Hydrogels also showed a 450 min water retention, as opposed to 280 min for pure water, evidencing good humidity control, suitable for use in arid climates. They also demonstrated a maximum release of commercial fertilizer of about 400 mg per gram for KH2PO4 and about 300 mg per gram for NPK 20‐5‐20. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

ObjectiveTo assess the prevalence of anti–carbamylated protein (anti‐CarP) antibodies in a French cohort of patients with early arthritis and to investigate their association with clinical features, final diagnosis, prognosis, and comorbidities.MethodsThe presence of anti‐CarP antibodies among patients with early arthritis in the French Etude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort (n = 720) was determined using enzyme‐linked immunosorbent assay. We investigated the prevalence of anti‐CarP antibodies in different patient subgroups stratified according to anti–citrullinated protein antibody (ACPA) and/or rheumatoid factor (RF) status. Diagnostic and prognostic values of the test were evaluated in this population.ResultsAnti‐CarP antibodies were present in approximately one‐third of the patients (32.6%) and in 23.6% of the patients who were seronegative for both RF and ACPA. Anti‐CarP positivity was associated with a more active disease status at baseline and over time. Anti‐CarP–positive patients had a significantly higher Disease Activity Score in 28 joints using the erythrocyte sedimentation rate at month 36 than anti‐CarP–negative patients (3.1 ± 0.11 versus 2.8 ± 0.06; P = 0.03). Anti‐CarP–positive early arthritis was associated with a higher risk of developing erosions after 96 months of follow‐up (55.6% of anti‐CarP–positive patients versus 37.3% of anti‐CarP–negative patients) (odds ratio 2.1 [95% CI 1.2–3.6]; P = 0.009). This association was particularly true when anti‐CarP was associated with ACPA positivity. Moreover, ACPA positivity alone in early arthritis was not associated with a higher risk of erosive evolution.ConclusionOur findings indicate that anti‐CarP antibodies are present in one‐third of patients with early arthritis and in one‐fourth of the RF‐negative and ACPA‐negative patients. They are particularly associated with a more severe radiographic outcome. Anti‐CarP antibody positivity may help to accurately identify those at risk of erosive evolution in an early arthritis population.
Toward the identification of adaptive functioning intervention targets for intellectually‐able, transition‐aged youth with autism: An examination of caregiver responses on the Vineland‐II

Little is known about specific adaptive functioning impairments in intellectually‐able individuals with autism spectrum disorder. In adolescents (n = 22) and young adults (n = 22) matched on composite IQ scores, this study examined profiles of cognitive and adaptive functioning, and caregiver responses on individual Vineland‐II items. Adaptive functioning standard scores were significantly lower than IQ scores, and the adult group had significantly lower adaptive functioning standard scores than the adolescent group. Examination of caregiver responses to individual Vineland‐II items identified more than 100 potential intervention targets. Differences favoring the adult group were observed on only 16 items across all three adaptive functioning domains, suggesting that little skill development is occurring during the transition to adulthood. Future research will examine the relevance of identified intervention targets to optimal outcomes. Autism Res 2017, 10: 2023–2036. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryAdolescents and young adults with autism spectrum disorder (ASD) without intellectual disability demonstrated impaired adaptive functioning skills (i.e., age appropriate skills necessary for independent living). Development of adaptive functioning skills appears to slow with age among individuals without intellectual disability. Findings clarify the specific adaptive functioning skills that transition‐aged youth with ASD have difficulty completing independently and will inform the development of interventions to increase the likelihood of independent living in adulthood.

Abstract5‐Fluorouracil (5‐FU), an anticancer drug, causes severe gastrointestinal damage, which may affect the absorption of orally administered drugs including the substrates of intestinal uptake and efflux transporters. This study aimed to investigate quantitatively the effect of 5‐FU‐induced intestinal damage on the expression of intestinal transporters: P‐glycoprotein (P‐gp), breast cancer resistance protein (BCRP) and peptide transporter 1 (PEPT1) in rats. The rats were treated with 5‐FU (30 mg/kg/day, p.o.) for 5 days to induce intestinal damage, and then the upper, middle and lower intestinal segments were removed. The mRNA and protein expression levels of these transporters in each segment were determined using quantitative real‐time PCR and Western blotting, respectively. In the 5‐FU‐treated rats, the protein levels of P‐gp and Bcrp in the upper segment were significantly increased to 15‐ and 2.6‐fold of the control, respectively, while those in other segments were unaffected. Pept1 expression was increased by 5‐FU in almost all segments. A remarkable increase in P‐gp expression was shown, the uptake of digoxin, a P‐gp substrate, in each intestinal segment was measured using a rat everted sac. As a result, the uptake of digoxin in the upper segments of 5‐FU‐treated rats was decreased compared with that of the control. In conclusion, 5‐FU‐induced intestinal damage was shown to alter the expression of these transporters, especially in the upper intestinal segment, while the characteristics of the influence varied among the transporters. The 5‐FU‐induced intestinal damage may affect transporter‐mediated drug absorption of orally administered drugs in the clinical setting.

Published: August 2017

AbstractFew studies have explored the relationship between green products development (GPD) and product portfolio management (PPM). When considering evidence from emerging economies, the knowledge gap is even deeper. Consequently, the objective of this work is to analyze how green and traditional practices of new product development (NPD) influence product portfolio and NPD performance. In addition, we explore how GPD opens new markets and technology opportunities. The empirical evidence is based on a sample of firms that are developing products and belong to innovative industrial sectors in Brazil. In general, the framework developed and tested in this research indicates the following: (i) the adoption of GPD practices significantly influences product portfolio performance; (ii) the adoption of GPD practices tends to generate positive results with regard to obtaining technological and market opportunities; (iii) the adoption of traditional PPM practices influences the dependent factors. Unexpectedly, correlations between a firm's size or age and its performance were not confirmed. This is the first empirical evidence relating GPD, PPM, and market and technology opportunities in Brazil. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
SIRT1 mediates salidroside‐elicited protective effects against MPP+‐induced apoptosis and oxidative stress in SH‐SY5Y cells: involvement in suppressing MAPK pathways

Published: August 2017

AbstractParkinson's disease (PD) is a progressive neurodegenerative disease, leading to tremor, rigidity, bradykinesia, and gait impairment. Salidroside has been reported to exhibit antioxidative and neuroprotective properties in PD. However, the underlying neuroprotective mechanisms effects of salidroside are poorly understood. Recently, a growing body of evidences suggest that silent information regulator 1 (SIRT1) plays important roles in the pathophysiology of PD. Hence, the present study investigated the roles of SIRT1 in neuroprotective effect of salidroside against N‐methyl‐4‐phenylpyridinium (MPP+)‐induced SH‐SY5Y cell injury. Our findings revealed that salidroside attenuates MPP+‐induced neurotoxicity as evidenced by the increase in cell viability, and the decreases in the caspase‐3 activity and apoptosis ratio. Simultaneously, salidroside pretreatment remarkably increased SIRT1 activity, SIRT1 mRNA and protein levels in MPP+‐treated SH‐SY5Y cell. However, sirtinol, a SIRT1 activation inhibitor, significantly blocked the inhibitory effects of salidroside on MPP+‐induced cytotoxicity and apoptosis. In addition, salidroside abolished MPP+‐induced the production of reactive oxygen species (ROS), the up‐regulation of NADPH oxidase 2 (NOX2) expression, the down‐regulations of superoxide dismutase (SOD) activity and glutathione (GSH) level in SH‐SY5Y cells, while these effects were also blocked by sirtinol. Finally, we found that the inhibition of salidroside on MPP+‐induced phosphorylation of p38, extracellular signal‐regulated kinase (ERK) and c‐Jun NH2‐terminal kinase (JNK) were also reversed by sirtinol in SH‐SY5Y cells. Taken together, these results indicated that SIRT1 contributes to the neuroprotection of salidroside against MPP+‐induced apoptosis and oxidative stress, in part through suppressing of mitogen‐activated protein kinase (MAPK) pathways.

Rational Design of Rod‐Like Liquid Crystals Exhibiting Two Nematic Phases
Authors: Mandle Richard J. , Cowling Stephen J. , Goodby John W. 
Published: August 2017

AbstractRecently, a polar, rod‐like liquid‐crystalline material was reported to exhibit two distinct nematic mesophases (termed N and NX) separated by a weakly first‐order transition. Herein, we present our initial studies into the structure–property relationships that underpin the occurrence of the lower‐temperature nematic phase, and report several new materials that exhibit this same transformation. We have prepared material with significantly enhanced temperature ranges, allowing us to perform a detailed study of both the upper‐ and lower‐temperature nematic phases by using small‐angle X‐ray scattering. We observed a continuous change in d spacing rather than a sharp change at the phase transition, a result consistent with a transition between two nematic phases, structures of which are presumably degenerate.

Published: August 2017

AbstractThis paper presented a study on the role of yttrium addition to Ru‐based catalysts for liquid phase paranitrotoluene hydrogenation reaction. An impregnation‐precipitation method was used for preparation of a series of yttrium doped Ru/NaY catalysts with yttrium content in the range of 0.0026–0.0052 g/g. Properties of the obtained samples were characterized and analyzed by X‐ray diffraction (XRD), H2‐TPR, Transmission electron microscopy (TEM), ICP atomic emission spectroscopy, and Nitrogen adsorption‐desorption. The results revealed that catalytic activity of NaY supported Ru catalysts increased with the yttrium content at first, then decreased with the further increase of yttrium content. When yttrium content was 0.0033 g/g, a Ru‐Y/NaY2 catalyst showed the most excellent performance of paranitrotoluene hydrogenation reaction (paranitrotoluene conversion and the selectivity toward P‐methyl‐cyclohexylamine reached 99.9 % and 82.5 %, respectively). In addition, to compare with the performance of Ru‐Y/NaY catalysts, the active carbon supported Ru catalysts were prepared using the same method in view of its higher surface area and adsorption capacity. Finally, the effect of solvent on the reaction over Ru‐Y/NaY2 catalyst has been investigated, it was found that the best performance of paranitrotoluene hydrogenation reaction took place in protic solvents (isopropanol and ethanol). This was mainly ascribed to their polarity and hydrogen‐bond accepting capability.
