AbstractSearching for a connection between the two‐electron redox behavior of Group‐14 elements and their possible use as platforms for the photoreductive elimination of chlorine, we have studied the photochemistry of [(o‐(Ph2P)C6H4)2GeIVCl2]PtIICl2 and [(o‐(Ph2P)C6H4)2ClGeIII]PtIIICl3, two newly isolated isomeric complexes. These studies show that, in the presence of a chlorine trap, both isomers convert cleanly into the platinum germyl complex [(o‐(Ph2P)C6H4)2ClGeIII]PtICl with quantum yields of 1.7 % and 3.2 % for the GeIV–PtII and GeIII–PtIII isomers, respectively. Conversion of the GeIV–PtII isomer into the platinum germyl complex is a rare example of a light‐induced transition‐metal/main‐group‐element bond‐forming process. Finally, transient‐absorption‐spectroscopy studies carried out on the GeIII–PtIII isomer point to a ligand arene–Cl. charge‐transfer complex as an intermediate.

AbstractThalattosuchians were a predominately marine clade of Mesozoic crocodylomorphs, including semi‐aquatic teleosauroid and obligately pelagic metriorhynchid subclades. Recent advances in our understanding of thalattosuchian endocranial anatomy have revealed new details of the evolutionary transition from terrestrial to marine to pelagic taxa. Paranasal sinuses, however, have received little attention. Herein, we investigate the evolution of the paranasal sinus system and part of the upper respiratory system (nasopharyngeal ducts) in Thalattosuchia, by reconstructing the nasal and paranasal anatomy in CT scans of seven thalattosuchian skulls: one teleosauroid, two basal metriorhynchoids and four metriorhynchids. Our outgroups were: three extant crocodylian species (including adult and subadult skulls) and the basal crocodyliform Protosuchus. We found thalattosuchians exhibit exceptionally reduced paranasal sinus systems, solely comprising the antorbital sinus, as has been previously proposed. The semi‐aquatic basal thalattosuchians Palgiopthalmosuchus gracilirostris and Pelagosaurus typus both have an antorbital sinus partially located medial to a reduced external antorbital fenestra and broadly communicating with the dorsal alveolar canal. In pelagic metriorhynchids, the antorbital cavity is more extensive than in basal taxa and possibly had an active function associated with a hypothesized accessory suborbital diverticulum, but our reconstructions are insufficient to confirm or reject the presence of such a diverticulum. The nasopharyngeal ducts of metriorhynchids are dorsoventrally enlarged, possibly enabling stronger ventilation. The sequence of acquisition of craniofacial adaptations show a mosaic pattern and appears to predate many skeletal adaptations, suggesting these changes occurred early in the thalattosuchian marine transition.
Green intellectual capital and environmental management accounting: Natural resource orchestration in favor of environmental performance

Published: August 2021

AbstractTaking inspiration from the natural resource‐based view of the firm and resource orchestration theory, we propose a new approach, that is, natural resource orchestration, to investigate how green intellectual capital and environmental management accounting stimulate environmental performance. Using survey data collected from 106 chief financial officers (CFOs) of publicly listed companies in Iran, findings show that the elements of green intellectual capital (green human capital, green structural capital, and green relational capital) are positively associated with both environmental management accounting and environmental performance. In addition, findings support the hypothesis that the use of environmental management accounting mediates the relationship between green intellectual capital and environmental performance. This study provides fresh insights into how an organization deals with the effective alignment (i.e., orchestration) of various green resources, for example, green intellectual capital and environmental management accounting, to promote environmental performance. This is the first study ever to introduce the natural resource orchestration approach for examining how environmental management accounting appears to play a role in translating green intellectual capital into enhanced environmental performance.

AbstractEndophytic fungi are an important class of microorganisms, able to interact with a host plant via a mutualistic mechanism without visible symptoms of the fungal colonization. The synergy between endophytic fungi and their host plant can promote morphological, physiological and biochemical changes through the expression of bioactive metabolites. This work aims to correlate metabolic changes in the Combretum lanceolatum plant metabolome with its endophytic fungi Diaporthe phaseolorum (Dp) and Trichoderma spirale (Ts), and to discover corresponding metabolite‐biomarkers, with the principal focus being on its primary metabolism. The 1H‐NMR metabolomic analysis of qualitative and quantitative changes was performed through multivariate statistical analysis and the identification of primary metabolites was achieved on the Madison Metabolomics Consortium Database. The presence of Dp significantly impacted the plant's metabolic pathways, improving the biosynthesis of primary metabolites such as threonine, malic acid and N‐acetyl‐mannosamine, which are precursors of special metabolites involved in plant self‐defence. This work represents a valuable contribution to advanced studies on the metabolic profiles of the interaction of plants with endophytes.

AbstractThe Society for Cardiovascular Angiography and Interventions (SCAI) Think Tank is a collaborative venture that brings together interventional cardiologists, administrative partners, and select members of the cardiovascular industry community annually for high‐level field‐wide discussions. The 2021 Think Tank was organized into four parallel sessions reflective of the field of interventional cardiology: (a) coronary intervention, (b) endovascular medicine, (c) structural heart disease, and (d) congenital heart disease. Each session was moderated by a senior content expert and co‐moderated by a member of SCAI's Emerging Leader Mentorship program. This document presents the proceedings to the wider cardiovascular community in order to enhance participation in this discussion, create additional dialog from a broader base, and thereby aid SCAI, the industry community and external stakeholders in developing specific action items to move these areas forward.

AbstractHeterotopic pregnancy (HP) describes the simultaneous presence of two pregnancies at different implantation sites. Usually, one pregnancy is intrauterine and the other one is ectopic. The incidence of HP after assisted reproductive technologies reaches 1:3900, but is very rare after a spontaneous pregnancy, with a reported incidence of 1 to 30,000 pregnancies.Due to its rarity, complex clinical picture, and laboratory findings, it is challenging to diagnose HP. We present a case of spontaneous HP diagnosed in the first trimester by ultrasound (US) and magnetic resonance imaging (MRI) and subsequently managed successfully. We present an analysis of the clinical and laboratory findings as well as imaging, including MRI that we used to diagnose the condition. Additionally, we performed a literature review.ConclusionsHP is a very rare condition frequently faced in obstetrics, gynecology, and emergency departments that requires a high index of clinical suspicion. US remains the imaging modality of choice in diagnosing a HP, however, in some cases, an MRI with a reported safety in the first trimester, can be used to provide additional information over US.

Published: August 2021

AbstractThe supported ionic liquid phase (SILP) concept, which included thin films of ionic liquid dispersed onto porous support surfaces, was applied for the gas‐phase hydroformylation of but‐1‐ene catalyzed by Rh‐bpp (bpp=biphephos ligand) complexes. The support material silica was carefully pre‐treated by a hydrothermal procedure to induce textural changes concerning the pore size. Starting with a mean pore size of 3 nm these could be enlarged by almost a factor of 10 up to 27 nm. Different particle size fractions having the same pore size of 10±1 nm were investigated regarding the hydroformylation activity. A clear limitation by pore diffusion can be found for particles larger than 500 μm in diameter. The limitation could be minimized by enlarging the pore size. To support the data, dimensionless numbers and criteria were calculated, including Thiele‐modulus, Mears, and Weisz‐Prater. All data support the assumption that limitation occurs around 500 μm particle size if 10 nm pores are present.
Understanding the Enhancement of Electrocatalytic Activity toward Hydrogen Evolution in Alkaline Water Splitting by Anodically Formed Oxides on Ni and C‐containing Ni

Published: August 2021

AbstractNickel oxides/hydroxides are active electrocatalysts for the hydrogen evolution reaction (HER) in alkaline water electrolysis. A durable activity of Ni with Ni(OH)2 was observed mainly on porous substrates, such as nickel foam or carbon cloth. Herein, we examined the effect of anodic oxidation on the HER using smooth samples of Ni, Ni with graphene, and Ni with C introduced by a low‐temperature plasma treatment. Electrochemical measurements in 1.0 M KOH showed that a strong activation toward HER was achieved by voltammetric cycling to potentials of the formation of Ni3O4, Ni2O3, and/or NiO2. The presence of C enhanced this activation. The effect of C was explained by the accumulation of larger amounts of these products as a result of a deteriorated passivity, their higher compactness (demonstrated by higher impedance), and the longer durability under conditions of HER (revealed by a slower cathodic reduction). The durability of oxides in porous C structures can be explained by anodic potentials in pores owing to the ohmic potential drop. It is proposed that anodic oxidation might be used for the reactivation of Ni cathodes for water electrolysis.

AbstractAlthough X‐ray absorption spectroscopy (XAS) was conceived in the early 20th century, it took 60 years after the advent of synchrotrons for researchers to exploit its tremendous potential. Counterintuitively, researchers are now developing bench type polychromatic X‐ray sources that are less brilliant to measure catalyst stability and work with toxic substances. XAS measures the absorption spectra of electrons that X‐rays eject from the tightly bound core electrons to the continuum. The spectrum from 10 to 150 eV (kinetic energy of the photoelectrons) above the chemical potential—binding energy of core electrons—identifies oxidation state and band occupancy (X‐ray absorption near edge structure, XANES), while higher energies in the spectrum relate to local atomic structure like coordination number and distance, Debye‐Waller factor, and inner potential correction (extended X‐ray absorption fine structure, EXAFS). Combining XAS with complementary spectroscopic techniques like Raman, Fourier transform infrared (FTIR), X‐ray photoelectron spectroscopy (XPS), and electron paramagnetic resonance (EPR) elucidates the nature of the chemical bonds at the catalyst surface to better understand reaction mechanisms and intermediates. Because synchrotrons continue to be the light source of choice for most researchers, the number of articles Web of Science indexes per year has grown from 1000 in 1991 to 1700 in 2020. Material scientists and physical chemists publish an order of magnitude articles more than chemical engineers. Based on a bibliometric analysis, the research comprises five clusters centred around: electronic and optical properties, oxidation and hydrogenation catalysis, complementary analytical techniques like FTIR, nanoparticles and electrocatalysis, and iron, metals, and complexes.

BackgroundThe Bethesda System for Reporting Thyroid Cytopathology contains an atypia of undetermined significance (AUS) category with heterogeneous and distinct inclusion criteria. The purpose of this study was to investigate differences in malignancy rates and molecular alterations based on the presence of different criteria.MethodsA laboratory information search was conducted to identify thyroid fine‐needle aspiration specimens signed out as AUS. The cases were reclassified as architectural atypia (3A), cytologic atypia (3C), both architectural and cytologic atypia (3B), or Hürthle cell aspirate (3H). Surgical follow‐up and concurrent molecular test results, if available, were collected.ResultsFive hundred ten specimens, including 258 reclassified as 3A, 40 reclassified as 3B, 119 reclassified as 3C, and 86 reclassified as 3H, were identified. The risks of malignancy for the subcategories were 13.4%, 26.3%, 44.1%, and 13.8%, respectively. Additionally, BRAF V600E mutations were more prevalent in specimens with cytologic atypia (3B/3C), whereas low‐risk alterations, including KRAS, PTEN, and PAX8‐PPARy2, were more prevalent in those with architectural atypia (3A).ConclusionsSubdividing AUS specimens on the basis of the type of atypia can yield categories associated with distinct molecular alterations and risks of malignancy.

Published: August 2021

SummaryWith the emergence of intelligent vehicles, how to satisfy the demands of the vehicles with computing‐intensive and delay‐sensitive tasks has become a challenging issue. Vehicular edge computing (VEC) is proposed as an advanced paradigm to improve the service of vehicles through offloading the task to the VEC servers. Nevertheless, VEC servers always have limited computation resources and do not satisfy the offloading requirements of vehicles. To this end, in this paper, we propose a more flexible offloading scheme by jointly considering the offloading strategies and the price strategy. In the proposed scheme, where the task can be dynamically divided into two parts parallel executed at the vehicles and VEC servers. A multi‐leader and multi‐follower Stackelberg game ‐based distributed algorithm is proposed to maximize the utilities of the vehicles and the VEC servers under the delay constraint. Finally, the game equilibrium is analyzed and achieved. Extensive experiments demonstrate that the proposed offloading scheme converges fast and always outperforms the existing schemes in terms of the vehicular utility under different network conditions. For instance, the proposed scheme achieves the utility improvement over 56.62% compared to the fixed selection strategy and achieves the utility improvement up to 161.0% compared to the complete offloading with fixed price strategy when the number of vehicles is 10. Additionally, the effects of key parameters such as the offloading strategies and, the price strategy, and the computation resource on the average utility of vehicles are also discussed and analyzed based on the simulation results.

AbstractObjectiveAlthough individuals with eating disorders (EDs) often experience significant body dissatisfaction and perceptual body image distortions, the presence and impact of weight misperception in clinical samples have been minimally examined. The aims of this study were to quantify weight misperception in individuals with EDs, examine whether weight misperception predicts ED severity at treatment discharge, and explore changes in weight misperception across treatment.MethodParticipants were 98 women seeking residential treatment for their ED who reported weekly on their perceived weight. Objectively measured weight was subtracted from perceived weight to determine weekly “weight misperception.” Participants completed the Eating Disorder Examination Questionnaire (EDE‐Q) at intake and discharge to assess ED severity. Weight misperception at intake and change in weight misperception over treatment were examined as predictors of ED pathology at discharge.ResultsApproximately 74.5% of the sample overestimated their weight, with an average weight misperception of 2.7 (SD = 5.6) pounds (1.2 kg; SD = 2.5). Weight misperception spanned from −6.2 to 43.6 pounds (−2.8 to 19.8 kg) and did not differ based on ED diagnosis. On average, weight misperception increased throughout treatment. Greater weight misperception at intake as well as greater increases in weight misperception over treatment significantly predicted EDE‐Q scores at discharge.DiscussionFindings highlight that weight misperception is not limited to underweight patients. Misperceiving one's weight may predict symptom severity across a range of EDs, and future research is needed to examine whether targeting weight misperception during residential treatment could improve treatment outcomes for individuals with EDs.
Prostaglandin regulation of type 2 inflammation: From basic biology to therapeutic interventions
Authors: Oyesola Oyebola O. , Tait Wojno Elia D. 
Published: August 2021

AbstractType 2 immunity is critical for the protective and repair responses that mediate resistance to parasitic helminth infection. This immune response also drives aberrant inflammation during atopic diseases. Prostaglandins are a class of critical lipid mediators that are released during type 2 inflammation and are integral in controlling the initiation, activation, maintenance, effector functions, and resolution of Type 2 inflammation. In this review, we explore the roles of the different prostaglandin family members and the receptors they bind to during allergen‐ and helminth‐induced Type 2 inflammation and the mechanism through which prostaglandins promote or suppress Type 2 inflammation. Furthermore, we discuss the potential role of prostaglandins produced by helminth parasites in the regulation of host–pathogen interactions, and how prostaglandins may regulate the inverse relationship between helminth infection and allergy. Finally, we discuss opportunities to capitalize on our understanding of prostaglandin pathways to develop new therapeutic options for humans experiencing Type 2 inflammatory disorders that have a significant prostaglandin‐driven component including allergic rhinitis and asthma.
