AbstractRecently, the creation of new heterogeneous catalysts using the unique electronic/geometric structures of small metal nanoclusters (NCs) has received considerable attention. However, to achieve this, it is extremely important to establish methods to remove the ligands from ligand‐protected metal NCs while preventing the aggregation of metal NCs. In this study, the ligand‐desorption process during calcination was followed for metal‐oxide‐supported 2‐phenylethanethiolate‐protected gold (Au) 25‐atom metal NCs using five experimental techniques. The results clearly demonstrate that the ligand‐desorption process consists of ligand dissociation on the surface of the metal NCs, adsorption of the generated compounds on the support and desorption of the compounds from the support, and the temperatures at which these processes occurred were elucidated. Based on the obtained knowledge, we established a method to form a metal‐oxide layer on the surface of Au NCs while preventing their aggregation, thereby succeeding in creating a water‐splitting photocatalyst with high activity and stability.

Published: May 2021

AbstractSilicone is a synthetic polymer widely used in the biomedical industry as implantable devices since 1940, owing to its excellent mechanical properties and biocompatibility. Silicone biomaterials are renowned for their biocompatibility due to their inert nature and hydrophobic surface. A timeline illustration shows critical development periods of using silicone in varied biomedical applications. In this review, silicone properties are discussed along with several biomedical applications, including medical inserts, speciality contact lenses, drains and shunts, urinary catheters, reconstructive gel fillers, craniofacial prosthesis, nerve conduits, and metatarsophalangeal joint implants. Silicones are prone to microbial infections when exposed and interactions with the host tissue. As in the case of medical inserts, the development of specific antimicrobial strategies is essential. The review highlights silicone implants' interaction with soft and bone tissue and various antimicrobial strategies, including surface coating, physical or chemical modifications, treating with antibiotics or plasma‐activated surfaces to develop the resistance to bacterial infection. Finally, 3D printing technology, tissue engineering, regenerative medicine applications, and future trends are also critically presented, indicating the silicone's potential as a biomaterial.
The pandemic crisis as a crisis of the symbolic order and psychoanalytic work regarding imaginary objects
Authors: Küchenhoff Joachim 
Published: May 2021

AbstractThe title of the article already indicates the structure of the text. In the first part, it is argued that the Corona crisis is a crisis as it challenges the symbolic order in many ways. The virus becomes an imaginary object that is uncanny. In the second part, psychoanalytic work on the uncanny object (how is it dealt with?) and work with the uncanny object (how can work be done under the conditions of the uncanny?) are discussed.

AbstractBioprinting three‐dimensional (3D) tissue equivalents have progressed tremendously over the last decade. 3D bioprinting is currently being employed to develop larger and more physiologic tissues, and it is of particular interest to generate vasculature in biofabricated tissues to aid better perfusion and transport of nutrition. Having an advantage over manual culture systems by bringing together biological scaffold materials and cells in precise 3D spatial orientation, bioprinting could assist in placing endothelial cells in specific spatial locations within a 3D matrix to promote vessel formation at these predefined areas. Hence, in the present study, we investigated the use of bioprinting to generate tissue‐level capillary‐like networks in biofabricated tissue constructs. First, we developed a bioink using collagen type‐1 supplemented with xanthan gum (XG) as a thickening agent. Using a commercial extrusion‐based multi‐head bioprinter and collagen‐XG bioink, the component cells were spatially assembled, wherein the endothelial cells were bioprinted in a lattice pattern and sandwiched between bioprinted fibroblasts layers. 3D bioprinted constructs thus generated were stable, and maintained structural shape and form. Post‐print culture of the bioprinted tissues resulted in endothelial sprouting and formation of interconnected capillary‐like networks within the lattice pattern and between the fibroblast layers. Bioprinter‐assisted spatial placement of endothelial cells resulted in fabrication of patterned prevascularized constructs that enable potential regenerative applications in the future.

AbstractBackgroundAlthough aggression is conceptualized as a dimensional construct with violent behavior representing the extreme end of a spectrum, studies on the involvement of personality traits in human aggression have typically only included data representing a restricted spectrum of aggressive behaviors.MethodsIn the current study, we therefore examine whether trait aggression is associated with five‐factor model personality traits in an enriched sample of 259 men with a broad continuum of trait aggression, ranging from very low to very high including 39 incarcerated aggressive violent offenders. All participants completed the NEO Personality Inventory‐Revised (NEO PI‐R) and the Buss–Perry Aggression Questionnaire (BPAQ). The association between each of the five NEO PI‐R personality traits and trait aggression (BPAQ) was investigated using five linear regression models, covarying for group status, age and educational level.ResultsHigher BPAQ scores were positively associated with Neuroticism and negatively associated with Agreeableness and Conscientiousness.ConclusionOur results indicate that those high in Neuroticism and low in Agreeableness and Conscientiousness are at higher risk of exhibiting aggressive behavior, underlining the relevance of these higher order personality traits in understanding aggressive behavior. We argue that studying individual personality differences should be offered a greater attention within violent and criminal behaviors.

AbstractAlthough the literature on eco‐friendly strategies followed by firms is abundant, the focus on the reduce, reuse, and recycle (3Rs) policies as the cornerstone of environmental sustainability is scarce. This study examines the 3Rs environmental strategy among 143 large organizations in the hospitality industry. We use the resource‐based view (RBV) of the firm theory to test the strategy's determinants and its impact on business performance on a suggested conceptualization level. As hypothesized, green corporate governance and environmental management systems, along with slack financial resources, were found to positively influence the adoption of a 3Rs environmental strategy. In turn, the implementation of the latter leads to superior business performance, measured in terms of operating profits and Tobin's Q. The study has several implications on a theoretical, managerial, and public policy level where intriguing directions for future research are provided.
Corporate climate‐related voluntary disclosures: Does potential greenwash exist among Australian high emitters reports?
Authors: Wedari Linda Kusumaning , Jubb Christine , Moradi‐Motlagh Amir 
Published: May 2021

AbstractThis study examines the issue of greenwashing among corporate high emitters subject to government scrutiny. To do so, we investigate the relationship between the actual environmental performance, measured as carbon emissions, of companies subject to the Australian National Greenhouse Energy Reporting Act 2007 (NGER) and their climate‐related voluntary disclosures. To measure climate‐related disclosure, we construct a climate‐related disclosure index based on four prominent frameworks and score corporate report content against that Index. Using a sample of 150 companies with NGER emissions data for Years 2016 and 2017, a period that precedes the issuance of recommendations for disclosure by the Task Force on Climate‐Related Financial Disclosure (TCFD), our regression results show a disappointingly low level of climate‐related disclosure by most companies. We also find a negative relationship between climate‐related disclosure and 1‐year lagged environmental performance among companies exhibiting a year‐on‐year rise in carbon emissions. That is, our findings provide evidence of potential greenwashing by poor environmental performers, presumably to change negative perceptions by stakeholders, as predicted by socio‐political theories. In contrast, we find no evidence of greenwashing among companies experiencing a year‐on‐year decrease in emissions.

AbstractRecent studies indicate that umbilical cord stem cells are cytoprotective against several disorders. One critical limitation in using stem cells is reduction in their viability under stressful conditions, such as diabetes. However, the molecular intricacies responsible for diabetic conditions are not fully elucidated. In this study, we found that high glucose (HG) conditions induced loss of chaperone homeostasis, stabilized PTEN, triggered the downstream signaling cascade, and induced apoptosis and oxidative stress in Wharton's jelly derived mesenchymal stem cells (WJMSCs). Increased Carboxyl terminus of Hsc70 interacting protein (CHIP) expression promoted phosphatase and tensin homolog (PTEN) degradation via the ubiquitin‐proteasome system and shortened its half‐life during HG stress. Docking studies confirmed the interaction of CHIP with PTEN and FOXO3a with the Bim promoter region. Further, it was found that the chaperone system is involved in CHIP‐mediated PTEN proteasomal degradation. CHIP depletion stabilizes PTEN whereas PTEN inhibition showed an inverse effect. CHIP overactivation suppressed the binding of FOXO3a with bim. Coculturing CHIP overexpressed WJMSCs suppressed HG‐induced apoptosis and oxidative stress in embryo derived cardiac cell lines. CHIP overexpressing and PTEN silenced WJMSCs ameliorated diabetic effects in streptozotocin (STZ) induced diabetic rats and further improved their body weight and heart weight, and rescued from hyperglycemia‐induced cardiac injury. Considering these, the current study suggests that CHIP confers resistance to apoptosis and acts as a potentiation factor in WJMSCs to provide protection from degenerative effects of diabetes.
Do buyer–seller personality similarities impact compulsive buying behaviour?

Published: May 2021

AbstractThis study investigates the influence of buyer–seller personality similarities on compulsive buying behaviour in a dyadic setting. To provide insights into the gaps in previous research, we collected both buyer and corresponding seller data, and considered sellers' personalities. Specifically, using difference score analyses and variance‐based structural equation modelling, we analysed 1038 buyer–seller dyads in service encounters. Compared with the effects of individual buyers' personalities on compulsive buying, the combined personality results showed that buyer–seller agreeableness similarities increase the compulsive buying behaviour of agreeable buyers. On the other hand, buyer–seller similarities in openness and neuroticism reduce compulsive buying. A further analysis showed that buyer–seller interactions mediate the effect of their extraversion and openness similarities on compulsive buying, while buyers' shopping enjoyment mediates the effect of their extraversion and neuroticism similarities on compulsive buying. Overall, compulsive buyers have interpersonally different buying behaviours when their personalities match (differ) with their corresponding sellers'. Thus, marketers can match agreeable buyers with similar sellers to promote sales, while dissimilar sellers should be complemented with open‐minded and neurotic buyers, in particular, to reduce losses.

AbstractThe development of novel and operationally simple synthetic routes to carbene‐metal‐amido (CMA) complexes of copper, silver and gold relevant for photonic applications are reported. A mild base and sustainable solvents allow all reactions to be conducted in air and at room temperature, leading to high yields of the targeted compounds even on multigram scales. The effect of various mild bases on the N−H metallation was studied in silico and experimentally, while a mechanochemical, solvent‐free synthetic approach was also developed. Our photophysical studies on [M(NHC)(Cbz)] (Cbz=carbazolyl) indicate that the occurrence of fluorescent or phosphorescent states is determined primarily by the metal, providing control over the excited state properties. Consequently, we demonstrate the potential of the new CMAs beyond luminescence applications by employing a selected CMA as a photocatalyst. The exemplified synthetic ease is expected to accelerate the applications of CMAs in photocatalysis and materials chemistry.

Published: May 2021

AbstractImageJ and CellProfiler have long been leading open‐source platforms in the field of bioimage analysis. ImageJ's traditional strength is in single‐image processing and investigation, while CellProfiler is designed for building large‐scale, modular analysis pipelines. Although many image analysis problems can be well solved with one or the other, using these two platforms together in a single workflow can be powerful. Here, we share two pipelines demonstrating mechanisms for productively and conveniently integrating ImageJ and CellProfiler for (1) studying cell morphology and migration via tracking, and (2) advanced stitching techniques for handling large, tiled image sets to improve segmentation. No single platform can provide all the key and most efficient functionality needed for all studies. While both programs can be and are often used separately, these pipelines demonstrate the benefits of using them together for image analysis workflows. ImageJ and CellProfiler are both committed to interoperability between their platforms, with ongoing development to improve how both are leveraged from the other. © 2021 Wiley Periodicals LLC.Basic Protocol 1: Studying cell morphology and cell migration in time‐lapse datasets using TrackMate (Fiji) and CellProfilerBasic Protocol 2: Creating whole plate montages to easily assess adaptability of segmentation parameters

AbstractThe quality of the wheat (Triticum aestivum L.) grain is determined by several factors that lead to different physical, chemical, and/or rheological characteristics. Our aim was to evaluate the effects of the type of cultivar quality and agricultural region of production on parameters that define the commercial and industrial quality of wheat. A total of 3,486 wheat samples were collected from producer lots. The samples corresponded to commercial cultivars classified according to the quality type following a system used in Argentina which is based on the combination of commercial and baking quality indicators. These wheat varieties were produced in three different regions according to resource availability (fertility of the soil and average rainfall). The technological quality of the different grain samples and flours was determined by means of physicochemical analyses. The samples from the region of high resource availability with higher productivity and lower industrial quality differed from those from the regions of low and medium resource availability. Grain test weight and ash content were significantly affected by the interaction between the quality group of the cultivars and the region of origin. Grain protein and gluten contents were mainly conditioned by the resource availability of the region. However, the quality of the gluten was genetically conditioned by quality group of the cultivars. As results of the relationships among these parameters, most of the variables of flour quality (color, deformation energy, tenacity/extensibility ratio, and farinograph stability) would be explained by the interaction between the cultivar and the environment where it was grown.

AbstractAimsHigh resting heart rate (RHR), one abnormal manifestation of autonomic nervous system, is associated with metabolic disorders. However, the association between RHR and metabolic syndrome (MetS) and its components remains controversial. We aimed to explore the link between these two parameters.Materials and MethodsThe study included 6589 Dong adults (1434 cases of MetS) from the cross‐sectional survey of the China Multi‐Ethnic Cohort Study. Logistic regression model was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) and assess the association between RHR and MetS, clustered metabolic risk, and MetS components. Restricted cubic splines model was used to evaluate the dose response association.ResultsA positive association existed between RHR and MetS, and people in the highest RHR quartile had a higher MetS risk (OR 1.75 [95% CI 1.42–2.15]) than those in the lowest quartile. The clustered metabolic risk associated with RHR (p < 0.05). Furthermore, RHR was related to elevated blood pressure (BP), elevated triglycerides (TG) and elevated fasting plasma glucose (FPG); the ORs (95% CIs) for the highest versus lowest RHR quartile were 2.06 (1.75–2.43), 1.37 (1.17–1.62) and 2.53 (2.04–3.14), respectively. Similar results were found in sensitivity and subgroup analyses. Also, non‐linear dose response association existed between RHR and MetS and elevated levels of BP, TG and FPG (p < 0.001).ConclusionsRHR was related to increased risk of MetS, three MetS components (elevated BP, elevated TG and elevated FPG) and the clustered metabolic risk. RHR may be a useful indicator for MetS.

Published: May 2021

AbstractBackgroundMetamorphosis in marine species is characterized by profound changes at the ecophysiological, morphological, and cellular levels. The cnidarian Clytia hemisphaerica exhibits a triphasic life cycle that includes a planula larva, a colonial polyp, and a sexually reproductive medusa. Most studies so far have focused on the embryogenesis of this species, whereas its metamorphosis has been only partially studied.ResultsWe investigated the main morphological changes of the planula larva of Clytia during the metamorphosis, and the associated cell proliferation and apoptosis. Based on our observations of planulae at successive times following artificial metamorphosis induction using GLWamide, we subdivided the Clytia's metamorphosis into a series of eight morphological stages occurring during a pre‐settlement phase (from metamorphosis induction to planula ready for settlement) and the post‐settlement phase (from planula settlement to primary polyp). Drastic morphological changes prior to definitive adhesion to the substrate were accompanied by specific patterns of stem‐cell proliferation as well as apoptosis in both ectoderm and endoderm. Further waves of apoptosis occurring once the larva has settled were associated with morphogenesis of the primary polyp.ConclusionClytia larval metamorphosis is characterized by distinct patterns of apoptosis and cell proliferation during the pre‐settlement phase and the settled planula‐to‐polyp transformation.
