Published: November 2016

AbstractA facile hydrothermal strategy is developed for the synthesis of SnS2 nanoplates with specific exposed facets. The crystallographic structure and the specific exposed facets of as‐prepared SnS2 are confirmed by X‐ray diffraction, Raman spectroscopy and TEM analysis, and the surface electronic state and the chemical composition of samples are investigated by X‐ray photoelectron spectroscopy (XPS). The band gaps of SnS2 nanoplates are directly measured from UV/Vis absorption spectra, and their detailed band alignments are determined by Mott–Schottky plots and ultraviolet photoelectron spectroscopy (UPS) analysis, which are well supported by DFT calculations. Significant transient photocurrent responses under visible‐light irradiation from photoelectrochemical analysis reveal that SnS2 samples are active and stable visible‐light‐driven photocatalysts and that SnS2 nanoplates dominated by {101} exposed facets should be better photocatalysts than those dominated by {100} exposed facets. The photocatalytic activities of SnS2 nanoplates are examined in two typical reactions, that is, rhodamine B (RhB) degradation and hydrogen production from water splitting. As expected, SnS2 nanoplates dominated by {101} exposed facets exhibit distinctly higher activity than those dominated by {100} exposed facets in the photocatalytic RhB degradation. For hydrogen production from water splitting, SnS2 nanoplates dominated by {101} exposed facets exhibit significant photocatalytic activity resulting from their suitable band edges to realize the photocatalytic redox reaction, in great contrast to the inactive SnS2 nanoplates dominated by {100} exposed facets.
The neurobiological causes and effects of alloparenting
Authors: Kenkel William M. , Perkeybile Allison M. , Carter C. Sue 
Published: November 2016

ABSTRACTAlloparenting, defined as care provided by individuals other than parents, is a universal behavior among humans that has shaped our evolutionary history and remains important in contemporary society. Dysfunctions in alloparenting can have serious and sometimes fatal consequences for vulnerable infants and children. In spite of the importance of alloparenting, they still have much to learn regarding the underlying neurobiological systems governing its expression. Here, they review how a lack of alloparental behavior among traditional laboratory species has led to a blind spot in our understanding of this critical facet of human social behavior and the relevant neurobiology. Based on what is known, they draw from model systems ranging from voles to meerkats to primates to describe a conserved set of neuroendocrine mechanisms supporting the expression of alloparental care. In this review we describe the neurobiological and behavioral prerequisites, ontogeny, and consequences of alloparental care. Lastly, they identified several outstanding topics in the area of alloparental care that deserve further research efforts to better advance human health and wellbeing. © 2016 Wiley Periodicals, Inc.

Corporate Strategies in Environmental Governance: Marine harvest and regulatory change for sustainable aquaculture
Authors: Vormedal Irja 
Published: December 2016

AbstractFocusing on Marine Harvest ASA, the world's largest salmon producer, this article examines the role of corporations in promoting sustainable aquaculture and regulation, exploring why a leading multinational may choose to adopt and implement a proactive sustainability strategy. It develops a neo‐pluralist model for conceptualizing drivers behind proactive strategy formation, and finds that a company‐specific combination of simple and mixed motives linking profit‐maximization and risk calculations to a longer‐term normative sustainability agenda can explain why corporations become entrepreneurs for sustainability. It concludes with some reflections on implications of the findings for understanding business in environmental governance more broadly. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment
An in situ toxicity identification and evaluation water analysis system: Laboratory validation
Authors: Steigmeyer August J. , Zhang Jiamin , Daley Jennifer M. , Zhang Xiaowei , Burton G. Allen 
Published: November 2016

Abstract

It is difficult to assess the toxicity of a single stressor and establish a strong stressor–causality link when multiple stressors coexist. Toxicity identification evaluation (TIE) methodology uses a series of chemical and physical manipulations to fractionate compounds within a matrix and systematically identify potential toxicants. The current US Environmental Protection Agency application of TIE can provide valuable information but often lacks ecological realism and is subject to laboratory-related artifacts. An in situ TIE device (iTIED) was designed to assess the sources of toxicity in aquatic ecosystems. For this laboratory validation, each unit was equipped with a sorbent resin chamber, an organism exposure chamber, a water collection container, and a peristaltic pump. Chemical analyses of water processed by each iTIED unit were compared with both lethal and sublethal molecular responses of the organisms. The compound removal effectiveness of different sorbent resins was also compared. In addition to successfully fractionating diverse chemical mixtures, the iTIED demonstrated a potential for early detection of molecular biomarkers, which could identify chronic toxicity that may go unnoticed in traditional TIE assays. Utilizing this novel in situ system will reduce the uncertainty associated with laboratory-based simulations and aid management efforts in targeting compounds that pose the greatest threat.

Multiple linear combination (MLC) regression tests for common variants adapted to linkage disequilibrium structure
Authors: Yoo Yun Joo , Sun Lei , Poirier Julia G. , Paterson Andrew D. , Bull Shelley B. 
Published: November 2016

ABSTRACTBy jointly analyzing multiple variants within a gene, instead of one at a time, gene‐based multiple regression can improve power, robustness, and interpretation in genetic association analysis. We investigate multiple linear combination (MLC) test statistics for analysis of common variants under realistic trait models with linkage disequilibrium (LD) based on HapMap Asian haplotypes. MLC is a directional test that exploits LD structure in a gene to construct clusters of closely correlated variants recoded such that the majority of pairwise correlations are positive. It combines variant effects within the same cluster linearly, and aggregates cluster‐specific effects in a quadratic sum of squares and cross‐products, producing a test statistic with reduced degrees of freedom (df) equal to the number of clusters. By simulation studies of 1000 genes from across the genome, we demonstrate that MLC is a well‐powered and robust choice among existing methods across a broad range of gene structures. Compared to minimum P‐value, variance‐component, and principal‐component methods, the mean power of MLC is never much lower than that of other methods, and can be higher, particularly with multiple causal variants. Moreover, the variation in gene‐specific MLC test size and power across 1000 genes is less than that of other methods, suggesting it is a complementary approach for discovery in genome‐wide analysis. The cluster construction of the MLC test statistics helps reveal within‐gene LD structure, allowing interpretation of clustered variants as haplotypic effects, while multiple regression helps to distinguish direct and indirect associations.
Physiologically based pharmacokinetic model for ethyl tertiary‐butyl ether and tertiary‐butyl alcohol in rats: Contribution of binding to α2u–globulin in male rats and high‐exposure nonlinear kinetics to toxicity and cancer outcomes

Published: November 2016

AbstractIn cancer bioassays, inhalation, but not drinking water exposure to ethyl tertiary‐butyl ether (ETBE), caused liver tumors in male rats, while tertiary‐butyl alcohol (TBA), an ETBE metabolite, caused kidney tumors in male rats following exposure via drinking water. To understand the contribution of ETBE and TBA kinetics under varying exposure scenarios to these tumor responses, a physiologically based pharmacokinetic model was developed based on a previously published model for methyl tertiary‐butyl ether, a structurally similar chemical, and verified against the literature and study report data. The model included ETBE and TBA binding to the male rat‐specific protein α2u–globulin, which plays a role in the ETBE and TBA kidney response observed in male rats. Metabolism of ETBE and TBA was described as a single, saturable pathway in the liver. The model predicted similar kidney AUC0–∞ for TBA for various exposure scenarios from ETBE and TBA cancer bioassays, supporting a male‐rat‐specific mode of action for TBA‐induced kidney tumors. The model also predicted nonlinear kinetics at ETBE inhalation exposure concentrations above ~2000 ppm, based on blood AUC0–∞ for ETBE and TBA. The shift from linear to nonlinear kinetics at exposure concentrations below the concentration associated with liver tumors in rats (5000 ppm) suggests the mode of action for liver tumors operates under nonlinear kinetics following chronic exposure and is not relevant for assessing human risk.

Published: November 2016

AbstractTitanium alloys (Ti‐6Al‐4V and Ti‐6Al‐7Nb) are widely used for implants, which are characterized by high elastic modulus (∼110 GPa) with (α + β) structure and that may induce undesirable stress shielding effect and immune responses associated with the presence of toxic elements. In this regard, we have combined the attributes of a new alloy design and the concept of additive manufacturing to fabricate 3D scaffolds with an interconnected porous structure. The new alloy is a β‐type Ti‐24Nb‐4Zr‐8Sn (Ti2448) alloy with significantly reduced modulus. In the present study, we explore the biological response of electron beam melted low modulus Ti2448 alloy porous mesh structure through the elucidation of bioactivity and osteoblast functions. The cellular activity was explored in terms of cell‐to‐cell communication involving proliferation, spreading, synthesis of extracellular and intracellular proteins, differentiation, and mineralization. The formation of fine apatite‐like crystals on the surface during immersion test in simulated body fluid confirmed the bioactivity of the scaffold surface, which provided the favorable osteogenic microenvironment for cell‐material interaction. The combination of unique surface chemistry and interconnected porous architecture provided the desired pathway for supply of nutrients and oxygen to cells and a favorable osteogenic micro‐environment for incorporation (on‐growth and in‐growth) of osteoblasts. The proliferation and differentiation of pre‐osteoblasts and their ability to form a well mineralized bone‐like extracellular matrix (ECM) by secreting bone markers (ALP, calcium, etc.) over the struts of the scaffold point toward the determining role of unique surface chemistry and 3D architecture of the Ti2448 alloy mesh structure in modulating osteoblasts functions. © 2016 Wiley Periodicals, Inc.

Popdc1/Bves Functions in the Preservation of Cardiomyocyte Viability While Affecting Rac1 Activity and Bnip3 Expression
Authors: Kliminski Vitaly , Uziel Orit , Kessler‐Icekson Gania 
Published: November 2016

ABSTRACTThe Popeye domain containing1, also called Bves (Popdc1/Bves), is a transmembrane protein that functions in muscle regeneration, heart rate regulation, hypoxia tolerance, and ischemia preconditioning. The expression of Popdc1/Bves is elevated in cardiomyocytes maintained in serum free defined medium. We hypothesized that Popdc1/Bves is important for cardiomyocyte survival under the stress of serum deprivation and investigated the mechanisms involved. A deficit in Popdc1/Bves, achieved by siRNA‐mediated gene silencing, results in cardiomyocyte injury and death, upregulation of the pro‐apoptotic protein Bcl‐2/adenovirus E1B 19‐kDa interacting protein3 (Bnip3), as well as reduction in Rac1‐GTPase activity and in Akt phosphorylation. Combined Popdc1/Bves and Bnip3 silencing attenuated cell injury and prevented Bnip3 upregulation induced by the silencing of Popdc1/Bves alone. Chromatin immunoprecipitation indicated an increased binding of the transcription factor FoxO3 to the Bnip3 promoter although augmentation of FoxO3 in the nuclei was not detected. By contrast, the transcription factor NFκB was excluded from the nuclei of Popdc1/Bves deficient cardiomyocytes and exhibited decreased binding to the Bnip3 promoter. The data indicates that Popdc1/Bves plays a role in the preservation of cardiomyocyte viability under serum deficiency through the alteration of Rac1 activity and the regulation of Bnip3 expression by FoxO3 and NFκB transcription factors pointing to Popdc1/Bves as a potential target to enhance heart protection.

AbstractThe influence of the different side chain residues on the thermodynamic and kinetic parameters for complexation reactions of the Co2+ and Ni2+ ions has been investigated by using the isothermal titration calorimetry (ITC) technique supported by potentiometric titration data. The study was concerned with the 2 common tripodal aminocarboxylate ligands, namely, nitrilotriacetic acid and N‐(2‐hydroxyethyl) iminodiacetic acid. Calorimetric measurements (ITC) were run in the 2‐(N‐morpholino)ethanesulfonic acid hydrate (2‐(N‐morpholino) ethanesulfonic acid), piperazine‐N,N′‐bis(2‐ethanesulfonic acid), and dimethylarsenic acid buffers (0.1 mol L−1, pH 6) at 298.15 K. The quantification of the metal‐buffer interactions and their incorporation into the ITC data analysis enabled to obtain the pH‐independent and buffer‐independent thermodynamic parameters (K, ΔG, ΔH, and ΔS) for the reactions under study. Furthermore, the kinITC method was applied to obtain kinetic information on complexation reactions from the ITC data. Correlations, based on kinetic and thermodynamic data, between the kinetics of formation of Co2+ and Ni2+ complexes and their thermodynamic stabilities are discussed.

AbstractNew biosourced chiral cross‐linkers were reported for the first time in the synthesis of methyltestosterone (MT) chiral molecularly imprinted polymers (cMIPs). Isosorbide and isomannide, known as 1,4:3,6‐dianhydrohexitols, were selected as starting diols. The cMIPs were synthesized following a noncovalent approach via thermal radical polymerization and monitored by Raman spectroscopy. These cross‐linkers were fully characterized by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy and high‐resolution mass spectrometry. The cross‐polarization magic angle spinning 13C NMR, Fourier transform infrared spectroscopy, scanning electron microscopy, and specific surface areas following the Brunauer‐Emmett‐Teller (BET) method were used to characterize the cMIPs. The effect of stereochemistry of cross‐linkers on the reactivity of polymerization, morphology, and adsorption‐recognition properties of the MIP was evaluated. The results showed that the cMIP exhibited an obvious improvement in terms of rebinding capacity for MT as compared with the nonimprinted polymer (NIP).The highest binding capacity was observed for cMIP‐Is (27.298 mg g−1) for high concentrations (500 mg L−1). However, the isomannide homologue cMIP‐Im showed higher recovery—up to 65% and capacity for low concentrations (15 mg L−1). The experimental data were properly fitted by the Freundlich adsorption isothermal model.
Homogenized monthly upper‐air temperature data set for Australia
Authors: Jovanovic Branislava , Smalley Robert , Timbal Bertrand , Siems Steven 
Published: November 2016

ABSTRACTWe present a homogenized, monthly, upper‐air temperature data set comprising 22 stations across the Australian continent, as well as five Australian remote island sites. The data set is based on 2300 UTC radiosonde soundings, with most records starting in 1958. The data are mostly complete since that time, with missing data more frequent at higher levels. The quality control process involved the examination of station metadata and an objective statistical test to detect discontinuities in the data, for which monthly temperature series were adjusted. Homogenized temperature data were analysed at standard levels. The all‐Australian annual mean temperature shows statistically significant trends over the 1958–2011 period, larger than the trends in surface temperature. Over this period, the annual 850 and 700 hPa mean temperatures show positive trends of 0.21 and 0.16 °C decade−1, respectively, more than the surface temperature which shows positive trend of 0.12 °C decade−1. Mid‐troposphere (the 500, 400 and 300 hPa levels) also shows positive trends of 0.13, 0.15 and 0.20 °C decade−1, respectively. Trends are small and of reverse sign at levels that intercept the tropopause: +0.08 °C decade−1 at 200 hPa and −0.14 °C decade−1 at 150 hPa. In the lower stratosphere (at 100 hPa), temperature trend is strongly negative, −0.39 °C decade−1. A similar vertical structure in the trends was found for the remote islands. The homogenized upper‐air radiosonde records for the Australian region are an independent confirmation of the expected physical response to increased atmospheric greenhouse gas concentrations: (1) a general warming in the troposphere, (2) a cooling in the lower stratosphere and (3) a faster warming of the troposphere than the surface.
Intercomparison of projected changes in climate extremes for South Korea: application of trend preserving statistical downscaling methods to the CMIP5 ensemble
Authors: Eum Hyung‐Il , Cannon Alex J. 
Published: November 2016

ABSTRACTGlobal climate models (GCMs) provide the fundamental information used to assess potential impacts of future climate change. However, the mismatch in spatial resolution between GCMs and the requirements of regional applications has impeded the use of GCM projections for impact studies at a regional scale. This study applied statistical post‐processing methods that preserve long‐term temporal trends, bias‐correction/spatial disaggregation with detrended quantile mapping (SDDQM) and BCSD with quantile delta mapping (SDQDM), to downscale 20 CMIP5 GCM climate projections for daily precipitation, minimum temperature, and maximum temperature over South Korea. Using the downscaled CMIP5 climate projections, we investigated absolute changes in extreme indices between the reference and three 30‐year future periods. In addition, the biases in change signals from GCM projections for different statistical downscaling methods were compared to evaluate how well long‐term trends in indices are preserved. The results showed that the statistical downscaling methods significantly improved the skill in reproducing extreme indices. For temperature‐related extreme indices, we found strong significant trends while trends for precipitation‐related indices varied depending on the index and climate projection horizon. Specifically, more frequent, longer duration, and more intense hot extremes may occur under the CMIP5 climate projections, while corresponding decreases may occur for extreme cold indices. Prominent upward trends are found in extreme precipitation events. Regarding analysis of the bias in change signals, SDQDM, which explicitly preserves changes in all quantiles of the underlying variables, better preserved long‐term trends in extreme indices simulated by GCMs.

AbstractThe Australian Commission on Safety and Quality in Health Care (ACSQHC) coordinates nation‐wide audits of the National Inpatient Medication Chart (NIMC). Electronic Medication Management Systems (eMMS) are beginning to replace NIMCs in Australian hospitals. This article describes the NIMC audit experience in two Australian tertiary hospitals that have established eMMS. Medication charts at both hospitals were audited using the ACSQHC‐provided audit tools (2012 Version). At both hospitals, eMMS charts exhibited higher levels of compliance with audit criteria than NIMCs, except for documentation of indication for medication. With eMMS, both hospitals exceeded national averages on many audited parameters, with the exceptions of documentation of weight and indication for medication. eMMS produces clearer, more complete medication orders and patient information, which may improve quality and safety of prescribing and reduce medication errors. Feedback was provided to the ACSQHC regarding aspects of the NIMC audit that did not align with eMMS for consideration in future audits.
Isotope ratio mass spectrometry in combination with chemometrics for characterization of geographical origin and agronomic practices of table grape

Published: November 2016

AbstractBACKGROUNDAlthough table grape is one of the most cultivated and consumed fruits worldwide, no study has been reported on its geographical origin or agronomic practice based on stable isotope ratios. This study aimed to evaluate the usefulness of isotopic ratios (i.e. 2H/1H, 13C/12C, 15N/14N and 18O/16O) as possible markers to discriminate the agronomic practice (conventional versus organic farming) and provenance of table grape.RESULTSIn order to quantitatively evaluate which of the isotopic variables were more discriminating, a t test was carried out, in light of which only δ13C and δ18O provided statistically significant differences (P ≤ 0.05) for the discrimination of geographical origin and farming method. Principal component analysis (PCA) showed no good separation of samples differing in geographical area and agronomic practice; thus, for classification purposes, supervised approaches were carried out. In particular, general discriminant analysis (GDA) was used, resulting in prediction abilities of 75.0 and 92.2% for the discrimination of farming method and origin respectively.CONCLUSIONThe present findings suggest that stable isotopes (i.e. δ18O, δ2H and δ13C) combined with chemometrics can be successfully applied to discriminate the provenance of table grape. However, the use of bulk nitrogen isotopes was not effective for farming method discrimination. © 2016 Society of Chemical Industry
