Abstract
Multigenerational studies have become of great interest in ecotoxicology since the consequence of parental exposure to contaminants on offspring generations was established in situ or in laboratory conditions. The present study mainly examined the chronic effects of external Cs-137 gamma irradiation exposure at 4 dose rates (control, 0.5, 5, and 50 mGy h–1) on adult zebrafish (F0) exposed for 10 d and their progeny (F1) exposed or unexposed for 4 to 5 d. The main endpoints investigated included parental reproductive performance, embryo-larval survival, DNA alterations, and reactive oxygen species (ROS) production in F0 and F1. No effects on reproductive success, fecundity, or egg fertilization rate were observed. However, drastic effects were observed on F1 exposed to 50 mGy h–1, resulting in a mortality rate of 100%. The drastic effects were also observed when the progeny was not irradiated. It was demonstrated that the sensitivity of the embryos was mainly attributable to parental irradiation. Moreover, these drastic effects induced by adult irradiation disappeared over time when 10 d–irradiated adults were placed in a nonirradiated condition. Alterations in larval DNA were observed for the 3 dose rates, and an increase of ROS production was also shown for the 2 lowest dose rates. The present study improves our understanding of the consequences of parental exposure conditions to the progeny. Furthermore, it provides an incentive to take transmitted generational effects into account in ecological risk assessments. Environ Toxicol Chem 2019;38:2556–2567. © 2019 SETAC

Published: August 2019

AbstractThe anodic activity of anodic catalyst for borohydride oxidation reaction (BOR) and inhibiting the borohydride hydrolysis reaction (BHR) are crucial to development for direct borohydride fuel cells (DBFC). In this paper, binder free CoSnx‐B/Ni‐foam (x = 0, 0.33, 0.5, 1) anode catalysts for BOR were prepared by chemical reduction method. It is found that the tin (Sn) is favor for improving the catalytic activity of cobalt (Co) for BOR, meanwhile, the catalytic activity is in relation to Co/Sn atom ratios. A maximum power density of 158 mW cm−2 of DBFC anodic catalytic is achieved at 293 K using CoSn0.33‐B/Ni‐foam which is 1.58 times that of Co‐B/Ni‐foam (100 mW cm−2). The constant discharge test of DBFCs showed that the specific capacity or fuel conversion efficiency decrease with the catalytic activity increasing. However, for the same electrocatalyst, the fuel conversion efficiency increased with the discharge current grown, indicating that there is a BHR which was independent of electrocatalyst in the discharge process. The results showed that CoSnx‐B/Ni‐foam had superior activity for BOR, suggesting their potential application as anodes in DBFC.
Pricing executive stock options with averaging features under the Heston–Nandi GARCH model
Authors: Su Zhiwei , Wang Xingchun 
Published: August 2019

AbstractIn this paper, we focus on the pricing issue of four types of executive stock options (ESOs) in the Heston–Nandi generalized autoregressive conditional heteroskedasticity option pricing model. Based on the derived benchmark strike prices in the proposed framework, we obtain the closed‐form pricing formulae for four types of ESOs. In the numerical part, we investigate the sensitivity and cost efficiency of ESOs and suggest that systematic risk (stock β) and the fraction of wealth invested in restricted stock could impede the cost efficiency of ESOs.
The effects of high‐involvement work systems and shared leadership on team creativity: A multilevel investigation

Published: August 2019

AbstractUnderstanding how to effectively stimulate creative potential in the workplace through strategic human resource management (HRM) practices is critical to enhancing organizational competitiveness. This study investigates the effects of high‐involvement work systems (HIWS) on team creativity in terms of ability–motivation–opportunity theory and a team input–process–output model. It draws on a data set consisting of 668 employees from 112 teams in 41 organizations in China. The results reveal that HIWS are positively related to team creativity, not only directly, but also indirectly through a sequential mediating mechanism of involvement climate and shared leadership. We argue that when employees are placed in an autonomous work environment underpinned by HIWS, they will be more likely to be involved in creative activities and engage in mutual influence behaviors in their work teams, and lead each other to achieve a higher level of creativity. Our study extends the knowledge on strategic HRM/HIWS, shared leadership, and creativity.

Abstract
Although advanced materials (AdMs) are beneficial in many applications, questions remain as to whether they are more or less sustainable than the conventional materials that they may replace. Currently, there is no available tool to provide clarity to these questions. Traditional approaches for evaluating the sustainability of a chemical or material are usually not standardized, and as a result, the metrics used in sustainability measurements are subjective and often vary from assessor to assessor. Additionally, sustainability characterizations resulting from these approaches are typically presented qualitatively and are often vaguely drawn, making it difficult to confidently and transparently conclude that 1 material is more sustainable than another. This paper aims to address these gaps by enabling stakeholders involved in the production, use, or governance of AdMs to assess the sustainability of AdMs in a consistent, objective, and quantitative way using a multicriteria decision analysis (MCDA)–based model. The model proposed herein adapts a triple-bottom-line (TBL) framework from the Institution of Chemical Engineers (IChemE) and incorporates criteria weights identified through a stakeholder values assessment conducted by surveying AdM practitioners. Results from the stakeholder values assessment show that the perceived importance of the economic component of the TBL varies the most across stakeholders, and that practitioners providing responses from the perspective of a nongovernmental environmental advocacy group or a regulator of AdMs such as the United States Environmental Protection Agency were more likely to score and weigh economic indicators lower and environmental indicators higher compared to when responding from a business owner perspective. The resulting MCDA-based model allows stakeholders to assess the sustainability of an AdM or AdM-enabled product and compare it to product alternatives, predict how other stakeholders might score a product by identifying the extent to which components of the TBL are valued by other stakeholders, and identify which subcriteria contribute most to an improvement in a product's sustainability score.

Published: August 2019

ABSTRACTBased on cross‐sectional research linking poor reflective functionining (RF) to eating disorders, the current follow‐up study tested whether maternal RF would explain the variance of mothers’ and children's weight beyond the effects of maternal emotional dysregulation. During pregnancy (Time 1 [T1]), 51 women were administered the Difficulties in Emotion Regulation Scale (DERS) and interviewed using the Adult Attachment Interview (AAI). Seven months after delivery (Time 2 [T2]), mother–baby dyads who remained in the study (n = 44) were videotaped (Feeding Scale) during their feeding interaction. Last (Time 3 [T3]), the weight of the 34 children who were still in the study was collected at 3 years of age. Maternal AAI‐RF at T1 did not correlate with the DERS at T1 nor with the quality of the feeding interacions at T2. However, it correlated, significantly, with maternal body mass index (BMI) at T1, r = −.298, P = .034, and marginally significantly with baby's BMI at T3, r = −.296, P = .089. Moreover, multiple regression models showed a trend indicating that maternal AAI‐RF might explain the variance of mothers’ and children's weight beyond the effects of maternal emotional dysregulation. These findings suggest that working on maternal mentalization might contribute to helping prevent childhood obesity from pregnancy.

AbstractOxygen‐releasing polycaprolactone/calcium peroxide (PCL/CaO2) composite microspheres were fabricated via homogenization, electrospray with a single nozzle, and electrospray with a co‐axial nozzle, resulting in homogenized, single‐walled, and double‐walled microspheres, respectively. Scanning electron microscopy revealed that homogenized microspheres had pores, while electrosprayed microspheres did not. Alizarin Red S staining showed a core‐shell structure for double‐walled microspheres. In a hypoxia incubator, single‐walled, double‐walled, and homogenized microspheres could maintain oxygen tension in PBS at or above 10% for approximately 5, 4, and 3 days, respectively. All the PCL/CaO2 microspheres could support viability of pancreatic β‐cell line MIN6 cells in 2D cultures in a hypoxia incubator for 1 week, with the cells supported by double‐walled and homogenized microspheres exhibiting the highest and the lowest metabolic activity, respectively. For 3D MIN6 cell cultures in a hypoxia incubator, single‐walled and homogenized PCL/CaO2 microspheres led to the highest and the lowest live cell densities, respectively. Double‐walled and single‐walled microspheres provided the best support for 2D and 3D cultures, respectively, suggesting that they are suitable for different applications.

AbstractScaffolds are models designed to aid the interaction between cells and extracellular bone matrix, providing structural support for newly formed bone tissue. In this work, wollastonite with β‐TCP porous ceramic scaffolds was developed by the polymer sponge replication. Their microstructure, cell viability and bioactivity were tested. in vivo was performed to evaluate the use of a calcium silicate‐based implant in the repair of rabbit tibias. Holes were made in the both proximal and distal tibial metaphysis of each animal and filled with calcium silicate‐based implant, and in the left tibia, no implant were used, serving as control group. Animals underwent euthanasia after 30 and 60 days of study. The animals were submitted to clinical‐radiographic evaluations and their histology was analyzed by optical and scanning electron microscope. The studied calcium silicate implant provided biocompatibility and promoted bone formation, stimulating the process of bone repair in rabbits, features observed by gradual radiopacity shown in the radiographic evaluations.

AbstractAn aluminum metal–organic framework (Al‐MOF), [Al(OH)(BPDC)] (DUT‐5; BPDC = Biphenyl‐4,4′‐dicarboxylate), was synthesized using solvothermal reactions. The high surface area and micropores (approximately 1.2 nm) of DUT‐5 were characterized using N2 gas sorption measurements. The thermal stability of DUT‐5 and its phase purity were also investigated. The different amounts of DUT‐5 (0.1, 0.15, and 0.2 wt%) were successfully incorporated into the chitosan (CS) polymer to prepare a mixed matrix membrane (MMM) for the pervaporation of water/ethanol at 25°C. In particular, when 0.15 wt% of DUT‐5 was loaded, the DUT‐5@CS MMMs displayed excellent permeability and selectivity in ethanol/water separation. The results indicated that compared with pristine chitosan membranes, the flux of DUT‐5@CS membranes with 0.15 wt% loading significantly increased from 315 to 378 (g/m2 h−1) and the separation factor from 347 to 3,429. These promising results of the microporous Al‐MOF doped into chitosan MMMs reveal its good application potential for the bio‐ethanol separation processes.

AbstractHypoxia is a common pathological process caused by insufficient oxygen. Long noncoding RNAs (lncRNAs) have been proven to participate in this pathology. Hypoxia is reported to significantly reduce the secretion of tissue inhibitor of metalloproteinase 2 (TIMP2) and TIMP2 induces pheochromocytoma‐12 (PC12) cell cycle arrest. Thus, our study aimed to explore the mechanism by which lncRNA maternally expressed gene 3 (MEG3) was implicated in hypoxia‐induced PC12 cell injury through TIMP2 promoter methylation. To elucidate the potential biological significance of MEG3 and the regulatory mechanism between MEG3 and TIMP2, a hypoxia‐induced PC12 cell injury model was generated. The hypoxia‐exposed cells were subjected to a series of overexpression plasmids and short hairpin RNAs, followed by the measurement of levels of MEG3, TIMP2, lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), reactive oxygen species (ROS), Bcl‐2‐associated X protein, B‐cell lymphoma‐2, and caspase‐3, as well as the changes in MMP, cell proliferation, apoptosis, and cell cycle progression. On the basis of the findings, MEG3 was upregulated in hypoxia‐injured PC12 cells. MEG3 recruited methylation proteins DNMT3a, DNMT3b, and MBD1 and accelerated TIMP2 promoter methylation, which in turn inhibited its expression. Moreover, PC12 cells following MEG3 silencing and TIMP2 overexpression exhibited significantly decreased levels of LDH, MDA, and ROS along with cell apoptosis, yet increased SOD and MMP levels, as well as cell cycle entry to the S phase and cell proliferation. In conclusion, MEG3 silencing suppresses hypoxia‐induced PC12 cell injury by inhibiting TIMP2 promoter methylation. This study may provide novel therapeutic targets for hypoxia‐induced injury.

Published: August 2019

AbstractBrain‐derived neurotrophic factor (BDNF) and neurotrophin‐4/5 (NT‐4/5) are trophic factors belonging to the neurotrophin family; in addition to their trophic role, both neurotrophins play an important role in modulating corticostriatal synaptic transmission. Failures in BDNF supply and mitochondrial dysfunction are among the factors involved in the striatal degeneration that occurs in Huntington's disease (HD). While the effects of BDNF have been widely studied in striatal degeneration, the role of NT‐4/5 has been less addressed. NT‐4/5 does not appear to exert effects similar to those of BDNF in HD. The physiological roles of these molecules in corticostriatal transmission have been evaluated separately, and we have demonstrated that sequential exposure to both neurotrophins results in different modulatory effects on corticostriatal transmission depending on the exposure order. In the present study, we evaluated the effects of BDNF followed by NT‐4/5 or NT‐4/5 followed by BDNF on corticostriatal synaptic transmission with field recordings in a male mouse model of HD produced by in vivo treatment with the mitochondrial toxin 3‐nitropropionic acid. Here, we show that these neurotrophins elicit an antagonistic or synergistic effect that depends on the activation of the truncated isoform or the stimulation of the full‐length isoform of the tropomyosin receptor kinase B.
Can reanalysis products with only surface variables assimilated capture Madden–Julian oscillation characteristics?

Published: August 2019

AbstractThe Madden–Julian Oscillation (MJO), as a dominant mode of tropical intraseasonal oscillation, plays an important role in the variability of global weather and climate. However, current state‐of‐the‐art atmospheric circulation models have difficulty in reproducing observed MJO characteristics when forced by observed daily sea surface temperature alone. An important practical question is how much data a model needs in assimilation to reproduce real MJO events? By analysing ERA‐20C and NOAA‐20CR reanalysis data, the authors tried to figure out whether a model could reproduce observed MJO events by assimilating the observed surface signal alone. The phase propagation and vertical structure associated with MJO were compared between the reanalysis data and observations during 1979–2010. A total skill score considering both temporal correlation and spatial standard deviation were defined. The result showed that both ERA‐20C and NOAA‐20CR could reproduce the observed MJO characteristics very well, with the former superior to the latter, regardless of MJO intensity. Thus, a minimum requirement for an operational atmospheric model for MJO prediction is the assimilation of the observed surface signals.

AbstractBACKGROUNDThis study aimed to evaluate the possibility of cotton waste enrichment with glycine betaine (GB) for production of two strains (P9, P10) of king oyster (Pleurotus eryngii). Cotton waste was used as (100%) control (T0 = cotton waste) and augmented with various combinations of GB, (T1 = 2 mmol L−1, T2 = 4 mmol L−1, T3 = 6 mmol L−1, T4 = 8 mmol L−1 and T5 = 10 mmol L−1). The response of king oyster to GB was evaluated by earliness, yield, biological efficiency (BE), minerals (nitrogen, phosphorus, potassium, zinc (Zn), copper (Cu), magnesium (Mg), manganese (Mn), iron (Fe), sodium (Na), calcium (Ca)), total sugars, total soluble solids, reducing sugars, non‐reducing sugars, ascorbic acid, proximate (crude protein, carbohydrates, crude fibers, ash, fats) content of fruiting body and Fourier‐transform infrared (FTIR) spectroscopy analysis compared with the control substrate (cotton waste).RESULTSThe earliness, yield, and BE were higher as compared to control substrate and increased with an augmentation in the concentration of GB within the cotton waste. Two strains showed (on dry weight basis) 33.9–54.9 mg g−1 nitrogen, 6.8–12.5 mg g−1 phosphorus, 16.9–25.1 mg g−1 potassium, 40.5–64.2 mg kg−1 Zn, 17.1–37.3 mg kg−1 Cu, 1174–1325 mg kg−1 Mg, 20.1–29.1 mg kg−1 Mn, 129–265 mg kg−1 Fe, 779–835 mg kg−1 Ca), 6.3%–11.3% total sugars, 7.3–14.9 °Brix total soluble solids, 2.1–7.3% reducing sugars, 10.4–18.1% crude protein, 3.6–4.4% crude fiber and 5.6–16.7 mg (100 g)‐1 on various concentration of GB enrich cotton waste. Cotton waste enriched with GB significantly affected nutritional profile of king oyster mushroom.CONCLUSIONThe results revealed that GB enriched cotton waste can be used as an innovative substrate to enhance the yield and quality of king oyster mushroom. © 2019 Society of Chemical Industry

AbstractBackgroundSeprafilm did not decrease small bowel obstruction (SBO), but significantly decreased reoperation in patients with inflammatory bowel disease. However, the preventive effect in colon cancer remains unclear.MethodsWe conducted a randomized controlled trial in patients with colon cancer. The study group comprised 345 patients with colon cancer. In the seprafilm group (n = 166), two sheets of seprafilm were inserted under a midline incision. Patients who were admitted and required decompression were considered to have SBO.ResultsThe median follow‐up was 61.9 months. Patient characteristics were well balanced. There was no significant difference in the incidence of SBO between the seprafilm group (7.8%) and the control group (10.6%) (P = .46). In patients who underwent reoperation, SBO occurred in a midline incision in one patient and at other sites in four patients in the seprafilm group as compared with two patients and five patients, respectively, in the control group. Multivariate analysis showed that only a history of laparotomy was an independent risk factor for SBO.ConclusionsSeprafilm did not decrease SBO or reoperation in colon cancer. The incidence of SBO caused by adhesion to the midline incision was relatively low as compared with that caused by adhesion to other sites.
