Published: May 2023

AbstractIntroductionLow levels of youth‐reported self‐efficacy to cope with suicidal urges have been shown to prospectively predict repeat emergency department (ED) visits and suicide attempts, yet little is known about how self‐efficacy may change following receipt of crisis services or about factors that may strengthen self‐efficacy. Protective factors (e.g., parent‐reported youth competence, parent‐family connectedness, and receipt of mental health services) were examined in relation to self‐efficacy at the time of a psychiatric ED visit and 2 weeks later.MethodsParticipants were 205 youth (ages 10–17), presenting to a psychiatric ED due to a suicide‐related concern. Youth primarily identified as biological female (63%) and White (87%). Multivariate hierarchical linear regressions were used to examine candidate protective factors in relation to initial and follow‐up suicide coping self‐efficacy.ResultsSelf‐efficacy significantly improved in the 2 weeks following the ED visit. Parent‐family connectedness was positively related to suicide coping self‐efficacy at the time of the ED visit. Parent‐family connectedness and receipt of inpatient psychiatric care following the ED visit were associated with higher follow‐up suicide coping self‐efficacy.ConclusionsDuring the adolescent developmental period when suicidal thoughts and behaviors notably increase, study findings highlight potential malleable intervention targets, including parent‐family connectedness, that may strengthen suicide coping self‐efficacy.

Published: May 2023

Organizational culture in sports affects well-being, performance, and overall success. Although team culture has been explored within able-bodied teams, little is known about culture development within parasport. Using a descriptive case study approach, our study examined the culture development and experiences of an elite parasport team. Two semistructured individual telephone interviews were conducted with nine participants (athletes and staff), and one athlete-participant completed one interview. An inductive thematic analysis revealed two themes: approach to culture development and team culture components. Culture development was linked with facilitative leadership and important resources. This supported the team to create their shared values and mechanisms, including a behavioral framework, other artifacts (e.g., shared language and team motto), and a relaxed environment. These helped to maintain their agreed culture and benefited their well-being, progress, and team cohesion. Our results offer a starting point regarding research into the culture of elite parasport and have practical implications for managers, coaches, and psychologists.
Regulation of Pro-/Antioxidant Balance in Higher Plants by Nanoparticles of Metals and Metal Oxides
Authors: Venzhik Yu. V. , Deryabin A. N. 
Published: May 2023

Abstract
A comparative analysis of available data suggests that metal and metal oxide nanoparticles widely used in plant physiology participate in the regulation of pro-/antioxidant balance in higher plants. The dual role of nanoparticles is shown: on the one hand, they act as triggers of oxidative stress and, on the other hand, they can counteract stress development and improve the efficiency of the plant’s antioxidant system. Under abiotic stress conditions, nanoparticles can act as adaptogens, thus enhancing the antioxidant defense of plants. Possible mechanisms of nanoparticle action, as well as the prospects for their application in fundamental science and agriculture are discussed.

Published: May 2023

Introduction
Current guidelines recommend abstinence from supervisedcardiacrehabilitation (CR) exercise training for 6 weeks post-sternotomy. This practice is not based on empirical evidence, thus imposing potentially unnecessary activity restrictions. Delayed participation in CR exercise training promotes muscle atrophy, reduces cardiovascular fitness and prolongs recovery. Limited data suggest no detrimental effect of beginning CR exercise training as early as 2 weeks post-surgery, but randomised controlled trials are yet to confirm this. The purpose of this trial is to compare CR exercise training commenced early (2 weeks post-surgery) with current usual care (6 weeks post-surgery) with a view to informing future CR guidelines for patients recovering from sternotomy.

Methods and analysis
In this assessor-blind randomised controlled trial, 140 cardiac surgery patients, recovering from sternotomy, will be assigned to 8 weeks of twice-weekly supervised CR exercise training commencing at either 2 weeks (early CR) or 6 weeks (usual care CR) post-surgery. Usual care exercise training will adhere to current UK recommendations. Participants in the early CR group will undertake a highly individualised 2–3 week programme of functional mobility, strength and cardiovascular exercise before progressing to a usual care CR programme. Outcomes will be assessed at baseline (inpatient), pre-CR (2 or 6 weeks post-surgery), post-CR (10 or 14 weeks post-surgery) and 12 months. The primary outcome will be change in 6 min walk distance. Secondary outcomes will include measures of functional fitness, quality of life and cost-effectiveness.

Ethics and dissemination
Recruitment commenced on July 2017 and will complete by December 2019. Results will be disseminated via national governing bodies, scientific meetings and peer-reviewedjournals.

ObjectiveTo describe differences between North America and Europe in the perioperative management of patients undergoing surgical aortic valve replacement (SAVR).MethodsPatients with moderate or greater aortic stenosis or regurgitation requiring SAVR were enrolled in a prospective observational cohort evaluating the safety and efficacy of a new stented bioprosthesis at 25 centres in North America (Canada and the USA) and 13 centres in Europe (Germany, the Netherlands, France, the UK, Switzerland and Italy). While all patients underwent implantation with the same bioprosthetic model, perioperative management was left to the discretion of participating centres. Perioperative care was described in detail including outcomes up to 1-year follow-up.ResultsAmong 1118 patients, 643 (58%) were implanted in North America, and 475 (42%) were implanted in Europe. Patients in Europe were older, had a lower body mass index, less bicuspid disease and worse degree of aortic stenosis at baseline. In Europe, anticoagulant therapy at discharge was more aggressive, whereas length of stay was longer, and discharges directly to home were less common. Rehospitalisation risk was lower in Europe at 30 days (8.5% vs 15.9%) but converged at 1-year follow-up (26.5% vs 28.1%). Within continents, there were major differences between individual countries concerning perioperative management.ConclusionContemporary perioperative management of SAVR patients varies between North America and Europe in patient selection, procedural techniques, antithrombotic regimen and discharge management. Furthermore, rehospitalisation differed largely between continents and countries. Hence, geographical setting must be considered during design and interpretation of trials on SAVR.Trial registration numberNCT02088554.

Published: May 2023

Short duration, intensive grazing management with high stocking rates may result in sufficient turn-over of nitrogen (N) to compensate for production-limiting soil-N deficiencies for grass pasture. In central Alberta a 0.5 ha block was seeded to “Fleet” meadow bromegrass ( Bromus riparius Rehmann) in August 2002. Within this block, six fenced (9 m × 30 m) treatments were established in three replicates. They were (1) ungrazed—clip removal, (2) grazed—alone, (3) grazed—fertilizer, (4) grazed—fertilizer-compost, (5) grazed—hog manure, and (6) grazed—alfalfa ( Medicago sativa L.) grass. Measurements were conducted over a 4-year period between 2003 and 2006 and grazing occurred at identical times as vegetative mass permitted. Biomass was harvested before and after grazing for calculation of dry matter (DM) yield and biomass consumed. Sub-samples were used for determination of N concentration and in vitro digestibility. Mean herbage N-yield for grazed treatments was 131% of ungrazed and greatest for grazed-fertilizer and grazed-fertilizer plus compost. Grazed paddocks with no added N produced similar DM yield to those with added N. Estimated nitrogen fixation contributed an annual average of 82 kg ha−1 to herbage-N yield from the alfalfa-grass paddocks. Barley ( Hordeum vulgare L.) silage grown after termination of the grazed pastures produced 72% more herbage DM from grazed paddocks than ungrazed, but no significant ( P < 0.05) differences occurred among amendments.

The phylogeny of the species from Phrymaceae and Mazaceae has undergone many adjustments and changes in recent years. Moreover, there is little plastome information on the Phrymaceae. In this study, we compared the plastomes of six species from the Phrymaceae and 10 species from the Mazaceae. The gene order, contents, and orientation of the 16 plastomes were found to be highly similar. A total of 13 highly variable regions were identified among the 16 species. An accelerated rate of substitution was found in the protein-coding genes, particularly cemA and matK. The combination of effective number of codons, parity rule 2, and neutrality plots revealed that the codon usage bias is affected by mutation and selection. The phylogenetic analysis strongly supported {Mazaceae [(Phrymaceae + Wightiaceae) + (Paulowniaceae + Orobanchaceae)]} relationships in the Lamiales. Our findings can provide useful information to analyze the phylogeny and molecular evolution within the Phrymaceae and Mazaceae.
Vertex-Bipartition: A Unified Approach for Kernelization of Graph Linear Layout Problems Parameterized by Vertex Cover
Authors: Liu Yunlong , Li Yixuan , Huang Jingui 
Published: May 2023

The linear layout of graphs problem asks, given a graph [Formula: see text] and a positive integer [Formula: see text], whether [Formula: see text] admits a layout consisting of a linear ordering of its vertices and a partition of its edges into [Formula: see text] sets such that the edges in each set meet some special requirements. Specific linear layouts include [Formula: see text]-stack layout, [Formula: see text]-queue layout, [Formula: see text]-arch layout, mixed [Formula: see text]-stack [Formula: see text]-queue layout and others. In this paper, we present a unified approach for kernelization of these linear layout problems parameterized by the vertex cover number [Formula: see text] of the input graph. The key point underlying our approach is to partition each set of related vertices into two distinct subsets with respect to the specific layouts, which immediately leads to some efficient reduction rules. We first apply this approach to the mixed [Formula: see text]-stack [Formula: see text]-queue layout problem and show that it admits a kernel of size [Formula: see text], which results in an algorithm running in time [Formula: see text], where [Formula: see text] denotes the size of the input graph. Our work does not only confirm the existence of a fixed-parameter tractable algorithm for this problem mentioned by Bhore et al. (J. Graph Algorithms Appl. 2022), but also derives new results for the [Formula: see text]-stack layout problem and for the [Formula: see text]-queue layout problem respectively. We also employ this approach to the upward [Formula: see text]-stack layout problem and obtain a new result improving that presented by Bhore et al. (GD 2021). Last but not least, we use this approach to the [Formula: see text]-arch layout problem and obtain a similar result.
ROLE OF SPACE IN AN ECO-EPIDEMIC PREDATOR-PREY SYSTEM WITH THE EFFECT OF FEAR AND SELECTIVE PREDATION

Published: May 2023

In ecological systems, the fear of predation risk asserts a privilege to the prey species by restricting their exposure to the potential predators. It also imposes costs by constraining the exploration of optimal resources. Additional foods for predators play a pivotal role in the biological conservation programs. The predators have ability to distinguish between the susceptible and infected prey items, and they avoid the latter ones to reduce their fitness cost. A predator-prey model with disease in prey is investigated in this study with an aim to explore the effects of fear factor, additional foods and selective predation on the ecological systems. We also investigate the spatio-temporal model to incorporate the facts that the prey and predator populations perform active movements in the spatial directions for their biological relevance. Both the temporal and spatio-temporal models are analyzed through noteworthy mathematical as well as numerical techniques. Our simulation results show that the level of fear responsible for the reduction in the birth rate of susceptible prey, rate of disease transmission and the selective feeding behavior of predators have potentials to create instability in the ecosystem. In contrast, the level of fear responsible for reduction in the disease prevalence can restore stability in the ecosystem by killing the persistent oscillations. Our eco-epidemic system exhibits chaotic nature if the growth of predators due to additional food sources is very low. We find that the spatio-temporal model demonstrates different spatial patterns of the prey and predator populations in the ecosystem.

Abstract
Non-marine gastropod fossils are abundant in the Middle Jurassic Toutunhe Formation in the Ziniquanzi section of the southern Junggar Basin, Xinjiang, NW China, and in the Lower Jurassic Sangonghe Formation in the Tuziakeneigou section of Karamay in the northwestern Junggar Basin. Nine species attributed to the families Viviparidae, Valvatidae and Hydrobiidae and one undetermined species attributed to Truncatelloidea are systematically re-described. Most of these species are widely distributed in China and can be used for biostratigraphic correlation. The palaeoenvironment was reconstructed by using available sedimentological data combined with ecological data for extant gastropod relatives.
Linguistic capital and international circulation: a comparative study between Argentina, Brazil and Chile
Authors: Beigel Fernanda , Almeida Ana Maria , Piovani Juan Ignacio 
Published: May 2023

While the hyper centrality of English has been considered a central feature of the world academic system and an increasing tendency in the Latin American academic circuit, one that has been pushed by state scientific policies and by the beliefs of researchers, no attempt has been made so far to observe to which extent publication in English is indeed a requirement for developing an academic career in the region. We attempt to shed new light in this issue by exploring the results of a survey that compares the use of foreign languages in publications and the experiences of acquiring linguistic competence in English for researchers based in Argentina, Brazil and Chile. The results show a more complex reality than that advanced by the evidence of hyper centrality of English. Bibliodiversity and multilingualism seems to be more the norm than the exception among these researchers. A steady stream of publication in the national language was identified among them, as well as the use of other languages. As these results vary by disciplinary field and related to phd formation abroad, the article proposes a more nuanced view of the processes and dynamics of publication practices in the Southern Cone.

Published: May 2023

O artigo analisa as disputas entre elites para expansão de mercados ligados aos veículos rumo a setores populares. Tomamos dois casos como entrada empírica: o setor de leilões de carros usados, que opõe elite tradicional e elites financeiras globais; e as disputas entre seguradoras tradicionais e elites emergentes ligadas às associações de proteção veicular. Argumentamos que a recorrência do uso do termo confiança nesses conflitos evidencia a centralidade do crime, como fato ou ameaça, para a construção e funcionamento de mercados legais de veículos e produtos a eles ligados. O artigo é baseado em entrevistas e na observação participante em eventos; conferências e entrevistas disponíveis na internet; materiais secundários produzidos pelos atores engajados nas disputas; e projetos de lei e legislações.

Published: May 2023

Em meio à dificuldade dos governos em promover políticas e projetos participativos, testemunhamos processos emergentes de envolvimento da sociedade na construção de espaços coletivos. O objetivo desse artigo é colocar em discussão o potencial do Urbanismo Tático, das experiências na escala humana (ações que testam ideias e transformam os espaços urbanos) e das micropolíticas híbridas (iniciativas de pequena escala que promovem a interação entre poder público e a sociedade) em possibilitar a participação da sociedade na transformação de espaços públicos. Como caso referencial, investigamos o Programa de Praças de Nova York que promove a reconfiguração de segmentos viários subutilizados em praças e estudamos como o programa incorporou medidas temporárias e participativas, passando a representar uma micropolítica híbrida para a cidade.
Polycomb Group Protein CBX7 Represses Cardiomyocyte Proliferation Through Modulation of the TARDBP/RBM38 Axis

Background:
Shortly after birth, cardiomyocytes exit the cell cycle and cease proliferation. At present, the regulatory mechanisms for this loss of proliferative capacity are poorly understood. CBX7 (chromobox 7), a polycomb group (PcG) protein, regulates the cell cycle, but its role in cardiomyocyte proliferation is unknown.

Methods:

We profiled CBX7 expression in the mouse hearts through quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry. We overexpressed CBX7 in neonatal mouse cardiomyocytes through adenoviral transduction. We knocked down CBX7 by using constitutive and inducible conditional knockout mice (

Tnnt2-Cre;Cbx7
fl/+

and

Myh6-MCM;Cbx7
fl/fl

, respectively). We measured cardiomyocyte proliferation by immunostaining of proliferation markers such as Ki67, phospho-histone 3, and cyclin B1. To examine the role of CBX7 in cardiac regeneration, we used neonatal cardiac apical resection and adult myocardial infarction models. We examined the mechanism of CBX7-mediated repression of cardiomyocyte proliferation through coimmunoprecipitation, mass spectrometry, and other molecular techniques.

Results:

We explored
Cbx7
expression in the heart and found that mRNA expression abruptly increased after birth and was sustained throughout adulthood. Overexpression of CBX7 through adenoviral transduction reduced proliferation of neonatal cardiomyocytes and promoted their multinucleation. On the other hand, genetic inactivation of
Cbx7
increased proliferation of cardiomyocytes and impeded cardiac maturation during postnatal heart growth. Genetic ablation of
Cbx7
promoted regeneration of neonatal and adult injured hearts. Mechanistically, CBX7 interacted with TARDBP (TAR DNA-binding protein 43) and positively regulated its downstream target, RBM38 (RNA Binding Motif Protein 38), in a TARDBP-dependent manner. Overexpression of RBM38 inhibited the proliferation of CBX7-depleted neonatal cardiomyocytes.

Conclusions:
Our results demonstrate that CBX7 directs the cell cycle exit of cardiomyocytes during the postnatal period by regulating its downstream targets TARDBP and RBM38. This is the first study to demonstrate the role of CBX7 in regulation of cardiomyocyte proliferation, and CBX7 could be an important target for cardiac regeneration.
