A pandemia da Covid-19 obrigou os países a reorganizarem suas verbas e serviços de saúde para atender as milhares de demandas por atendimento. Apesar das doenças contagiosas serem atravessadas por questões de gênero e sexualidade, as medidas de enfrentamento não levaram em consideração as particularidades dos diferentes grupos, como da população LGBTQIA+. Nesse sentido, objetivou-se discutir os impactos da pandemia sobre o acesso aos serviços de saúde e a saúde física e mental desta população, a partir de uma revisão sistemática da literatura e análise de redes dos estudos extraídos das bases de dados WoS e PubMed. Os resultados foram divididos em três seções: “Particularidades e acesso aos serviços de saúde”; “Sintomas psiquiátricos, sofrimento psíquico e uso de substâncias psicoativas: estudos por país”; e “Análise de redes”. Identificou-se maior número de estudos em países desenvolvidos, como Estados Unidos e Canadá, e apenas dois estudos que incluem o Brasil. Verificou-se que, além da pandemia potencializar as barreiras de acesso aos serviços de saúde, aumentou a vulnerabilidade frente à infecção por coronavírus, os índices de sofrimento psíquico e transtornos psiquiátricos, como depressão e ansiedade, e do uso de substâncias lícitas e ilícitas, além de acarretar a fragilização dos vínculos sociais.

Importance

ERBB2-low (ie, ERBB2 immunohistochemistry score of 1+ or 2+ in the absence of ERBB2 gene amplification) breast cancer (BC) is a new entity, with emerging dedicated treatments. Little is known about its prognosis and response to conventional therapy compared with ERBB2-zero breast tumors (ie, those with an immunohistochemistry score of 0).

Objective

To compare the outcomes for patients with ERBB2-low metastatic BC (MBC) with those of patients with ERBB2-zero MBC.

Design, Setting, and Participants

This cohort study was conducted from the Epidemiological Strategy and Medical Economics MBC platform and included patients with MBC treated between 2008 and 2016 in 18 French comprehensive cancer centers. The data analysis was conducted from July 16, 2020, to April 1, 2022.

Main Outcomes and Measures

The main outcome was overall survival (OS), and the secondary outcome was progression-free survival under first-line treatments (PFS1).

Results

The median (range) age was 60.0 (22.0-103.0) years. Among 15 054 patients with MBC, 4671 (31%) had ERBB2-low MBC and 10 383 (69%) had ERBB2-zero MBC. The proportion of ERBB2-low cancers was higher among patients with hormone receptor–positive MBC than those with hormone receptor–negative disease (4083 patients [33.0%] vs 588 patients [21.0%]). With a median follow-up of 49.5 months (95% CI, 48.6-50.4 months), the median OS of the ERBB2-low group was 38.0 months (95% CI, 36.4-40.5 months) compared with 33.9 months (95% CI, 32.9-34.9 months) for the ERBB2-zero group (P < .001). After adjustment for age, visceral metastases, number of metastatic sites, de novo disease, period of care, and hormone receptor status, patients with ERBB2-low MBC had slightly better OS compared with patients with ERBB2-zero MBC (adjusted hazard ratio, 0.95; 95% CI, 0.91-0.99; P = .02). In contrast, PFS1 did not differ by ERBB2 status (adjusted hazard ratio, 0.99; 95% CI, 0.95-1.02; P = .45). No significant differences in OS and PFS1 were observed in multivariate analyses by hormone receptor status and types of frontline treatment.

Conclusions and Relevance

In this large cohort study, patients with ERBB2-low MBC had a slightly better OS than those with completely ERBB2-zero tumors, but identical PFS1, which could help guide treatment selection.
Methods of Analysis for the Determination of Veterinary Drugs in Food: Focus on Antimicrobials
Authors: Spisso Bernardete F. , Pereira Mararlene U. , Ferreira Rosana G.
Published: September 2022

An overview of the methods of analysis that are currently being used for the determination of veterinary drugs in food is presented. Hyphenated techniques, mainly those based on the coupling of chromatographic separation and mass spectrometry detection have proven to be more appropriate. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) with quadrupole mass analyzers is still the most used analytical technique for the purpose, but high‐resolution mass analyzers are becoming more accessible and more frequently employed, due to their capability of untargeted screening, elucidation power of molecular structures of unknown substances and retrospective analysis. Among the sample preparation methods, modified QuEChERS extractions have brought considerable benefits regarding simplifications of sample preparation steps, resulting in cheaper and high throughput methods for veterinary drugs in complex matrices such as foods. A trend to implement more cost‐effective methods has led to attempts to include veterinary drugs, pesticides, mycotoxins, and environmental contaminants in multi‐residue mega‐methods.

Published: September 2022

Lead (Pb) halide perovskites have attracted significant attention in the field of optoelectronics. However, due to the disadvantages associated with the presence of Pb in perovskite, its use should be minimized, if not completely eliminated. Herein, an efficient Pb‐free Sn‐based halide perovskite photodetector (PD) that is sensitive to visible and near‐infrared light is developed. The Sn perovskite is characterized with low toxicity and a narrow bandgap, and exhibits lower shunt leakage and a higher built‐in potential compared with a Pb‐based perovskite. Also, the relatively stronger bond strength between Sn and iodine ions in comparison with that observed in the Pb‐based perovskite effectively prevents charge injections that are vulnerable to dark current suppression. The Sn‐based perovskite PD demonstrates a high signal‐to‐noise ratio (SNR) of 51.12 dB, as well as an excellent cut‐off frequency of 763 kHz. To the best knowledge, this device is one of the fastest and most efficient photodiode‐type Sn‐based perovskite PDs developed to date. Unlike the Pb‐based perovskite device, the Sn‐based perovskite PD retains its high SNR over time. This effect may be attributed to the low movement of ion vacancies and degree of vertical shunt leakage in the perovskite material.

Published: September 2022

Layered 2D materials display unique optical and electrical properties that can enable manipulation, propagation, and detection of electromagnetic waves over a broad spectral range, with a high level of control, offering the potential to activate different functionalities, by optical or electrical means, in a single chip. Here, a compact optoelectronic device behaving as an amplitude modulator, saturable absorber mirror (SA mirror), and frequency‐tuner is conceived at terahertz (THz) frequencies. It comprises a gate‐tunable single layer graphene (SLG), embedded in a quarter‐wave cavity, operating in the 1–5 THz range. The use of electrolyte ionic liquid gate ensures 40% optical amplitude modulation depth. Z‐scan self‐mixing interferometry reveals 60% reflectivity modulation, with ≈4.5 W cm−2 saturation intensity. By integrating the modulator/SA mirror with a heterogeneous THz quantum cascade laser frequency comb, in an external cavity configuration, fine‐tuning of the intermode beatnote frequency is also demonstrated. This opens intriguing perspectives for short pulse generation, phase‐locking, frequency tuning/chirping, phase modulation, and metrological referencing, inter alia.

Bioelectronic devices that allow simultaneous accurate monitoring and control of the spatiotemporal patterns of cardiac activity provide an effective means to understand the mechanisms and optimize therapeutic strategies for heart disease. Optogenetics is a promising technology for cardiac research due to its advantages such as cell‐type selectivity and high space‐time resolution, but its efficacy is limited by the insufficient number of modulation channels and lack of simultaneous spatiotemporal mapping capabilities in current implantable cardiac optogenetics tools available for in vivo investigations. Here, soft implantable electro‐optical cardiac devices integrating multilayered highly uniform arrays of transparent microelectrodes and multicolor light‐emitting diodes in thin, flexible platforms are designed for mechanically compliant high‐content high‐precision electrical mapping and single‐/multi‐site optogenetics and electrical stimulation without light‐induced artifacts. Systematic benchtop characterizations, together with ex vivo and in vivo evaluations on healthy and diseased small animal hearts and human cardiac slices demonstrate their functionalities in real‐time spatiotemporal mapping and control of cardiac rhythm and function, with broad applications in basic and ultimately clinical cardiology.

Spinal cord injury (SCI) is a severe body trauma that can cause permanent loss of somatic nerve function and lacks effective treatment. Transplantation of stem cells is a promising therapeutic approach for SCI but faces with the difficulty of long‐term tracking of stem cells in vivo precisely. Herein, this work wishes to report a kind of umbilical cord mesenchymal stem cells (UC‐MSCs) labeled with aggregation‐induced emission (AIE)‐Tat nanoparticles (NPs) for tracing the repair and treatment of SCI. These AIE‐Tat NPs have strong fluorescence, good biocompatibility, and long‐term tracking ability with a high signal‐noise ratio. The labeling of AIE‐Tat NPs does not induce adverse effects on the activity and performance of UC‐MSCs. The fluorescence signal of the UC‐MSCs can be monitored for up to 28 days, reflecting the viability, colonization, and function of the transplanted UC‐MSCs. The transplantation of UC‐MSCs can secrete nerve growth factors and maintain the viability of cells in the highly reactive oxygen species microenvironment, leading to effective recovery of injured spinal cord, which is further confirmed by the behavioral rehabilitation and histopathological results. These findings demonstrate that long‐term tracking of UC‐MSCs labeled with AIE‐Tat NPs is a promising method to monitor stem cell transplantation therapy for SCI.

Published: September 2022

Metal‐air batteries as alternatives to the existing lithium‐ion battery are becoming increasingly attractive sources of power due to their high energy‐cost competitiveness and inherent safety; however, their low oxygen evolution and reduction reaction (OER/ORR) performance and poor operational stability must be overcome prior to commercialization. Herein, it is demonstrated that a novel class of hydrothermally grown dual‐phase heterogeneous electrocatalysts, in which silver‐manganese (AgMn) heterometal nanoparticles are anchored on top of 2D nanosheet‐like nickel vanadium oxide (NiV2O6), allows an enlarged surface area and efficient charge transfer/redistribution, resulting in a bifunctional OER/ORR superior to those of conventional Pt/C or RuO2. The dual‐phase NiV2O6/AgMn catalysts on the air cathode of a zinc‐air battery lead to a stable discharge–charge voltage gap of 0.83 V at 50 mA cm−2, with a specific capacity of 660 mAh g−1 and life cycle stabilities of more than 146 h at 10 mA cm−2 and 11 h at 50 mA cm−2. The proposed new class of dual‐phase NiV2O6/AgMn catalysts are successfully applied as pouch‐type zinc‐air batteries with long‐term stability over 33.9 h at 10 mA cm−2.
Mechanical Intelligence (MI): A Bioinspired Concept for Transforming Engineering Design
Authors: Khaheshi Ali , Rajabi Hamed
Published: September 2022

Despite significant scientific advances in the past decades, most structures around us are static and ironically outdated from a technological perspective. Static structures have limited efficiency and durability and typically perform only a single task. Adaptive structures, in contrast, adjust to different conditions, tasks, and functions. They not only offer multi‐functionality but also enhanced efficiency and durability. Despite their obvious advantages over conventional structures, adaptive structures have only been limitedly used in everyday life applications. This is because adaptive structures often require sophisticated sensing, feedback, and controls, which make them costly, heavy, and complicated. To overcome this problem, here the concept of Mechanical Intelligence (MI) is introduced to promote the development of engineering systems that adapt to circumstances in a passive‐automatic way. MI will offer a new paradigm for designing structural components with superior capabilities. As adaptability has been rewarded throughout evolution, nature provides one of the richest sources of inspiration for developing adaptive structures. MI explores nature‐inspired mechanisms for automatic adaptability and translates them into a new generation of mechanically intelligent components. MI structures, presenting widely accessible bioinspired solutions for adaptability, will facilitate more inclusive and sustainable industrial development, reflective of Goal 9 of the 2030 Agenda for Sustainable Development.

Mucus is a self‐healing gel that lubricates the moist epithelium and provides protection against viruses by binding to viruses smaller than the gel's mesh size and removing them from the mucosal surface by active mucus turnover. As the primary nonaqueous components of mucus (≈0.2%–5%, wt/v), mucins are critical to this function because the dense arrangement of mucin glycans allows multivalence of binding. Following nature's example, bovine submaxillary mucins (BSMs) are assembled into “mucus‐like” gels (5%, wt/v) by dynamic covalent crosslinking reactions. The gels exhibit transient liquefaction under high shear strain and immediate self‐healing behavior. This study shows that these material properties are essential to provide lubricity. The gels efficiently reduce human immunodeficiency virus type 1 (HIV‐1) and genital herpes virus type 2 (HSV‐2) infectivity for various types of cells. In contrast, simple mucin solutions, which lack the structural makeup, inhibit HIV‐1 significantly less and do not inhibit HSV‐2. Mechanistically, the prophylaxis of HIV‐1 infection by BSM gels is found to be that the gels trap HIV‐1 by binding to the envelope glycoprotein gp120 and suppress cytokine production during viral exposure. Therefore, the authors believe the gels are promising for further development as personal lubricants that can limit viral transmission.

Published: September 2022

Water scarcity and excessive N fertilization have a negative effect on maize (Zea mays L.) production. Low water and N fertilization are the major problem in sustainable agriculture by limiting crop growth and development. However, the combined effect of N fertilization and supplementary irrigation on chlorophyll fluorescence and maize yield is still not understood. The objective of the study was to signify the effect of supplementary irrigation and N fertilization on leaf area index (LAI), relative chlorophyll content (SPAD), maximum photosynthetic capacity (Fv/Fm), photochemical quenching coefficient (qP), and yield. The experiment was conducted in a split‐plot design, with water management in main plot and N fertilization in subplot with three replications. Treatments included two water managements, that is, rainfed (natural rainfall) and irrigation water (70% field capacity). Five N fertilization rates were N0 (0 kg N ha−1), N150 (150 kg N ha−1), N200 (200 kg N ha−1), N250 (250 kg ha−1), and N300 (300 kg N ha−1). The LAI, SPAD, Fv/Fm, qP, and yield were significantly affected by water management, N rates, and their interaction (P < .05). The LAI, SPAD, Fv/Fm, qP, total dry matter accumulation, and yield under supplementary irrigation were significantly increased by 10.99, 5.75, 6.57, 9.14, 15.64, and 14.58% than those under rainfed conditions, but the nonphotochemical quenching coefficient was significantly decreased by 22.82%. The 250 kg N ha−1 increased grain yield under irrigated conditions than that of other N treatments. The interaction between water management and N fertilization significantly and positively affected the SPAD, Fv/Fm, and grain yield in both years, but had no significant effect on LAI during 2021 and HI during 2020 and 2021. We concluded that N250 treatment with supplementary irrigation increased grain yield.
Silicon Catalyzed C−O Bond Ring Closing Metathesis of Polyethers
Authors: Ansmann Nils , Thorwart Thaddäus , Greb Lutz
Published: September 2022

The Lewis superacid bis(perchlorocatecholato)silane catalyzes C−O bond metathesis of alkyl ethers with an efficiency outperforming all earlier reported systems. Chemoselective ring contractions of macrocyclic crown ethers enable substrate‐specific transformations, and an unprecedented ring‐closing metathesis of polyethylene glycols allows polymer‐selective degradation. Quantum chemical computations scrutinize a high Lewis acidity paired with a simultaneous low propensity for polydentate substrate binding as critical for successful catalysis. Based on these mechanistic insights, a second‐generation class of silicon Lewis superacid with enhanced efficacy is identified and demonstrated.

PhI(OTf)2 and related ArI(OTf)2 species have been incorrectly invoked as intermediates in oxidation reactions for many years. We recently established that such compounds did not yet exist but remain an attractive target. Here we describe the synthesis, isolation, and structural characterization of NO2‐PhI(OTf)2, which is resistant to decomposition and more reactive than PhI(OTf)(OAc), the species previously misidentified as PhI(OTf)2.

Die enantioselektive C−H‐Aktivierung hat sich zu einem transformativen Werkzeug für den effizienten Aufbau chiraler Moleküle entwickelt. Trotz großer Fortschritte in der Rhodium‐ und Palladiumkatalyse hat sich die ruthenium(II)‐katalysierte enantioselektive C−H‐Aktivierung bisher jedoch als weitgehend herausfordernd erwiesen. Im Gegensatz dazu berichten wir nun über eine ruthenium(II)‐katalysierte hochregio‐, diastereo‐ und enantioselektive C−H‐Alkylierung. Als Schlüssel zum Erfolg wurden C2‐symmetrischen chiralen Imidazolidincarbonsäuren (CICAs), die leicht in einer Eintopfreaktion hergestellt werden können, als hochwirksame chirale Liganden identifiziert. Dieses Ruthenium/CICA‐System ermöglichte die effiziente Installation der zentralen und axialen Chiralität und verfügte über ausgezeichnete verzweigte bis lineare Verhältnisse mit im Allgemeinen >20 : 1 dr und bis zu 98 : 2 er. Experimentelle und computerchemische mechanistische Studien wurden durchgeführt, um die Wirkungsweise des Katalysators zu entschlüsseln.

Published: September 2022

N−N Atropisomers are a common motif in natural products and represent a significant dimension for exploration in modern pharmaceutical and medicinal chemistry. However, the catalytic atroposelective synthesis of such molecules remains challenging, hampering meaningful development. In particular, an enantioselective synthesis of N−N bisindole atropisomers is unprecedented. Herein, the first enantioselective synthesis of N−N bisindole atropisomers via the palladium‐catalyzed de novo construction of one indole skeleton is presented. A wide variety of N−N axially chiral bisindoles were generated in good yields with excellent enantioselectivities via a cascade condensation/N‐arylation reaction. Structurally diverse indole‐pyrrole, indole‐carbazole, and non‐biaryl‐indole atropisomers possessing a chiral N−N axis were accessed using this protocol. Moreover, investigations using density functional theory (DFT) calculations provided insight into the reaction mechanism and enantiocontrol.
Impact of dope extrusion rate and multilayer polydimethylsiloxane coating on asymmetric polyethersulfone hollow fiber membrane for CO2/N2 and CO2/CH4 separation
Authors: Zainuddin Muhd Izzudin Fikry , Ahmad Abdul Latif
Published: September 2022

Carbon dioxide (CO2) emissions to the atmosphere have greatly contributed to climate change as the concentration has increased since the pre‐industrial period. Various mitigation strategies have been developed to combat climate change with membrane being one of the growing alternatives. Pristine hollow fiber (HF) membrane typically exhibits lower selectivity as compared to dense flat sheet membrane. In this study, we developed an asymmetric HF polyethersulfone (PES) membrane with critical concentration at two different dope extrusion rate (DER) at 3 and 6 mL/min to be studied for CO2/N2 and CO2/CH4 gas separation for flue gas and biogas upgrading applications by testing the fabricated membrane with pure gas permeation test with variable pressure at room temperature. It was observed that HF membrane extruded with high DER exhibits finger‐like structure beneath the skin layer with more pinholes compared to HF extruded with low DER. The gas permeance was observed to increase in linear fashion as function of upstream pressure while the gas selectivity appears to be relatively constant regardless of upstream pressure. Meanwhile, polydimethylsiloxane (PDMS) coated HF PES membrane shows lower gas permeance as compared to its pristine membrane with improved CO2/N2 and CO2/CH4 selectivity. HF PES membrane extruded at 3 mL/min shows relatively low gas permeance, CO2/N2 and CO2/CH4 selectivity as compared to HF PES extruded at 6 mL/min. Additionally, this study shows that sequential coating of PDMS layer does not improve gas selectivity performance of the fabricated asymmetric PES HF membrane while the gas permeance reduction was observed.
Complete mitochondrial genome of Distenia punctulatoides (Coleoptera: Chrysomeloidea: Disteniinae) and its phylogenetic implications
Authors: Nie Ruie E. , Gao Rong‐Rong , Yang Xing‐Ke , Lin Mei‐Ying
Published: September 2022

The family Disteniidae is a moderately large and widely distributed lineage. Distenia punctulatoides belongs to the family Disteniidae from the cerambycoid assemblage. Here, we report the complete mitogenome of D. punctulatoides, which is 15,675 bp in length. It contains 37 genes and a noncoding control region, which are arranged in the same order as that of the putative ancestor of beetles. The total base composition of the new mitogenome is 40.2% for A, 17.1% for C, 10.0% for G, and 32.7% for T. The new mitogenomic organization, nucleotide composition, and codon usage do not differ significantly from other beetles. Using available complete mitogenomes, the high‐level phylogeny of the family Disteniidae was explored. The phylogenetic analyses showed that Disteniidae were monophyletic, and the genus Distenia grouped with the genus Clytomelegena as sister groups. Combining the morphological and molecular data, Typodryas Thomson, 1864 is suggested to be a junior synonym of Distenia Lepeletier and Audinet‐Serville, 1828.
Comparison of geophysical prospecting and geochemical prospecting at the medieval and modern Cistercian Abbey of Carnoët (Finistère, France)

Published: September 2022

Saint‐Maurice Abbey in Carnoët (Finistère) underwent an in‐depth archaeological appraisal during 2018–2019, involving several non‐destructive technologies: the geophysical survey revealed the presence of expected structures, drawn on ancient plans, but also the presence of structures unknown up until now. A group of buildings on the edge of the pond in particular raised several questions. A geochemical survey was carried out there in order to try to characterize these buildings and observe the potential complementarity between geophysical and geochemical surveys. The results of the chemical analysis do not highlight the same level of detail of the structures as electrical resistivity, but these analyses seem to be able to clarify the geophysical diagnosis by discriminating signals of structures from echoes linked to the geological substrate.
Spatial correction of low‐cost sensors observations for fusion of air quality measurements
Authors: Bobbia Michel , Poggi Jean‐Michel , Portier Bruno
Published: September 2022

The context for this article is the statistical fusion of several pollutant measurement networks: a reference one of fixed sensors of high quality and others of fixed or mobile micro‐sensors of heterogeneous quality. The challenge is to use together the measurements of such different networks to obtain a better air quality map. Since pollution maps are often obtained from the correction of numerical model outputs by the measurements provided by the monitoring stations of air quality networks, the quality of the reconstructed map may be improved by increasing the density of sensors by adding low‐cost micro‐sensors. A geostatistical approach is very often used for the fusion of measurements. But the first step is to correct micro‐sensors measures using those given by the reference sensors. Usually, this preprocessing is performed during an offline preliminary study for which reference and micro‐sensor are located at the same position, which does not allow to adapt quickly to changes and to cope with time‐related nonstationarities. We propose in this article to complement these approaches by a simple online spatial correction of micro‐sensors. The principle is to use the reference measurements to correct the network of micro‐sensors. More precisely, by kriging only the measurements from micro‐sensors, the reference measurements are estimated; allowing to calculate a correction by kriging the differences, finally applied to the micro‐sensors. Then one can iterate this fundamental sequence of steps. Numerical experiments exploring the proposed algorithm by simulation and an application to a real‐world dataset are provided.

Published: September 2022

This study examined the factors associated with social‐communicative outcomes for children on the autism spectrum receiving early intervention in inclusive versus specialised early childhood education programmes. Fifty‐eight preschool‐aged children randomly assigned to receive the Group‐Early Start Denver Model (G‐ESDM) in either inclusive or specialised (i.e., autism‐specific) classrooms across one calendar year showed similar outcomes at group mean‐level across measures of communication and social behaviour. We examined factors moderating outcomes across settings. Novel moderation analyses revealed that higher baseline social interest and nonverbal cognitive skills were associated with increased social communication gains for children in the inclusive classrooms, but not for those in specialised settings. Children who spend more time paying attention to people and have higher cognitive skills might benefit from receiving early intervention in inclusive settings, whilst these factors might be less relevant for children educated in specialised settings.

Authors: Dolenc‐Voljč Mateja , Povšič Katja , Kučič Alja Cmok , Gašperšič Rok
Published: September 2022

A patient presented with ulcerations of the buccal mucosae, palate and gingiva. A gingival biopsy confirmed the diagnosis as pemphigus vulgaris. Despite medication with systemic corticosteroids and mycophenolate mofetil, desquamative gingivitis persisted. Adjunct treatment with rituximab was therefore introduced. Regular follow‐ups revealed no inflammatory gingival changes even 6 years later.

Published: September 2022

Hematite is a suitable precursor to obtain catalytically active iron (oxide) phases for CO2 Fischer‐Tropsch synthesis after a reductive pretreatment. As concluded from in situ Raman spectroscopy, in hydrogen atmosphere the transformation from α‐Fe2O3 to Fe3O4 is faster than the further reduction from Fe3O4 to Fe (metallic iron). The rate of these steps highly depends on the temperature. Starting from pure hematite, surface formate species are formed at a CO2/H2 gas mixture at elevated temperatures, observable by DRIFT‐spectroscopy. The exposure to CO2 and CO led to surface carbonate‐carboxylate surface species. Reduced samples with varying contents of Fe3O4 and Fe did not show any observable adsorbates at reaction conditions. The same behavior was found during the dosage of the single gases CO2 and CO to these reduced catalysts. The formation of carbonaceous species, detected by Raman spectroscopy, could indirectly hint to the occurrence of carbidation and was especially observed for a good performing catalyst with a medium reduction degree.

The economics of advanced and unresectable hepatocellular carcinoma
Authors: Mattingly T. Joseph , Shetty Kirti
Published: September 2022

The cost‐effectiveness analysis by Li et al. offers important insights into value‐based therapy for advanced hepatocellular carcinoma; however, it is important to consider that their analysis focuses on a single binary decision. In practice, it is necessary to consider all available options for the patient.
Polarity Inversion of Ga‐Polar GaN Surfaces by Exposing to Mg and NH3 in Metal–Organic Vapor Phase Epitaxy
Authors: Li Chengguo
Published: September 2022

A metal–organic vapor phase epitaxy process of polarity inversion (PI) from Ga‐ to N‐polar is reported by exposing the Ga‐polar surface simultaneously to Mg and ammonia flows. This process differs from the conventional Mg heavy‐doping technique by intentionally predepositing a Mg‐rich thin layer on the Ga‐polar surface for PI. A full PI with a smooth surface in the subsequent GaN overgrowth is achieved by an exposure process for 900 s at 700 °C. Atomic force microscopy and piezo‐force microscopy characterizations reveal that the polarity change undergoes simultaneously with pyramid formation after ≈15 nm thick GaN overgrowth. The electron dispersion spectroscopy mapping of Mg indicates high Mg concentrations at the regrowth interface and in the PI domain boundary. A Mg‐rich thin layer is believed to cover the surface after the exposure process and release Mg dopants in the subsequent growth, leading to a high Mg incorporation in the GaN overlayer and therefore inducing PI. P‐type conduction with a hole concentration of ≈2.7 × 1017 cm−3 is achieved in the N‐polar GaN overlayer. It is also demonstrated that such a PI technique can be employed in the growth of a hybrid polarity structured ultraviolet‐light‐emitting diode with a reversed N‐polar contact layer on a Ga‐polar main body.
A Self‐Separating Multiphasic System for Catalytic Hydrogenation of CO2 and CO2‐Derivatives to Methanol
Authors: Diehl Thomas , Lanzerath Patrick , Franciò Giancarlo , Leitner Walter
Published: September 2022

Catalytic conversion of CO2 and hydrogen to methanol was achieved in a self‐separating multiphasic system comprising the tailor‐made complex [Ru(CO)ClH(MACHO‐C12)] (MACHO‐C12=bis{2‐[bis(4‐dodecylphenyl)phosphino]ethyl}amine) in n‐decane as the catalyst phase. Effective catalyst recycling was demonstrated for the carbonate and the amine‐assisted pathway from CO2 to methanol. The polar products MeOH or MeOH/H2O generated from the catalytic reactions spontaneously formed a separate phase, allowing product isolation and catalyst separation without the need for any additional solvent. In the amine‐assisted hydrogenation of CO2, the catalyst phase was recycled over ten subsequent runs, reaching a total turnover number to MeOH of 19200 with an average selectivity of 96 %.
A figurational viewpoint of the complexity of policy enactment: An opportunity for agonistic dialogue?
Authors: Scanlon Dylan , MacPhail Ann , Calderón Antonio
Published: September 2022

The aim of this paper is to explore and provide an alternative theoretical viewpoint, informed by empirical studies, of the curriculum policy enactment process which spans across different curriculum policy spaces by drawing on figurational sociology. This paper constructs this alternative figurational viewpoint of the policy enactment process by drawing on curriculum policy and policy enactment literature. This viewpoint highlights how a curriculum policy can be (re‐)interpreted, (re‐)translated and (re‐)enacted by multiple, interconnected and interdependent (face‐to‐face and non‐face‐to‐face, recognised and unrecognised, past and present) relationships. We argue the need for agonistic dialogue between the stakeholders of the educational community and how his could lead to these stakeholders working together across curriculum policy spaces (e.g., curriculum development, teacher education, professional development) and on different aspects of ‘doing’ policy work. We encourage ourselves, and colleagues, to advocate for, support and provide evidence on the centrality of construction and enactment of curriculum policy in effective curriculum change.

Lobaria pindarensis is an endemic species of the Himalayas and the Hengduan Mountains. Little information is available on the phylogeography genetics and colonization history of this species or how its distribution patterns changed in response to the orographic history of the Himalayas and Hengduan Mountains. Based on samples covering a major part of the species' distribution range, we used 443 newly generated sequences of nine loci for molecular coalescent analyses in order to reconstruct the evolutionary history of L. pindarensis, and to reconstruct the species' ancestral phylogeographic distributions using Bayesian binary MCMC analyses. The results suggest that current populations originated from the Yunnan region of the Hengduan Mountains in the middle Pliocene, and that the Himalayas of Bhutan were colonized by a lineage that diverged from Yunnan ca. 2.72 Ma. The analysis additionally indicates that the Nepal and Xizang areas of the Himalayas were colonized from Yunnan as well, and that there was later a second dispersal event from Yunnan to Bhutan. We conclude that the change in climate and habitat related to the continuous uplift of the Himalayas and the Hengduan Mountains in the late Pliocene and middle Pleistocene influenced the geographic distribution pattern of L. pindarensis.
Life history traits vary between geographically distinct populations in a protogynous hermaphrodite
Authors: Kolodzey Stina , Wing Stephen R.
Published: September 2022

Sequential hermaphroditic species, such as blue cod (Parapercis colias), are particularly vulnerable to selective harvesting as it can directly influence the sex ratio, timing of sex change, and consequentially recruitment success. We analyzed the population structure, at which males dominate the populations, and modeled fecundity of blue cod from the Marlborough Sounds in the north of New Zealand's South Island, and compared these results with previously collected data from a blue cod population in Fiordland on the southwest coast of the South Island. In addition to the geographical difference, there were differences in the time the two populations were sampled, and the fisheries management regime between regions. Within the Marlborough Sounds population, the length‐frequency distribution was skewed toward high numbers of smaller individuals with an average length of 290 ± 59 mm. In Fiordland, the average length of blue cod was 380 ± 78 mm. Larger proportions of males within each length class were observed in the Marlborough Sounds, whereas females were the dominant sex in the Fiordland population. The estimated length at which males dominate the population was significantly smaller for the Marlborough Sounds population (182 mm) than for blue cod from the Fiordland population (419 mm). Geographical and temporal differences in sampling likely played important roles in the observed life history differences, particularly in the observed differences in growth. However, when compared to length and age data from national surveys, the life history traits of both sampled populations have remained relatively stable over the past 15 years, indicating that differences in population management and fishing pressure are the most likely explanation for the observed differences in length frequency and length‐at‐sex‐change. For effective and sustainable management of species with sequential hermaphroditism, size‐sensitive management, particularly protecting larger individuals, is required to avoid declines in length structure and recruitment limitations.
