Authors: Gonçalves Brandão Santos Luana Carla , Lima da Silva Nathalia , Pereira do Nascimento Oliveira Keila Cristina , Santana Vieira Ana Carolina
Published: June 2021

Objetivo: analisar a relação entre orientações do pré-natal sobre o Sistema logí­stico/peregrinação e a internação do RN na UTIN em uma maternidade pública de alto risco. Métodos: Trata-se de um estudo descritivo, transversal de abordagem quanti-qualitativa, com 4 parturientes internadas na Maternidade Escola Santa Mônica (MESM) cujos RN"™s internos na Unidade de Terapia Intensiva Neonatal. O estudo aprovado pelo Comitê de Ética e Pesquisa com o parecer nº 2.145.000. Resultados: Sobre o perfil das puérperas, 67% tinham 24 anos, 80% cor parda e 33% com ensino fundamental incompleto. Referente ao sistema logí­stico, 50% foram orientadas no pré-natal sobre a maternidade de referência e 50% não receberam orientação. Conclusão: Através da análise dos prontuários percebe-se que muitas mulheres apresentam dúvidas que poderiam ter sido esclarecias durante o pré-natal, a peregrinação esteve associada a falta do conhecimento e das orientações.

Objetivo: analisar a relação da atividade fí­sica no lazer e de deslocamento ativo com a percepção do ambiente em pessoas com doenças crônicas não transmissí­veis. Métodos: estudo transversal constituí­do por 719 usuários do SUS. Para a coleta de dados utilizou-se o IPAQ e o Neighborhood Environmental Walkability Scale. Utilizou-se o teste qui-quadrado de Pearson e o modelo de regressão logí­stica. Resultados: dos 719 (100%), 512 (71,2%) participantes eram do sexo feminino e 504 (70,1%) relataram ter doença crônica não transmissí­vel. Não há relações entre mulheres com doença crônica e percepção do ambiente para a prática de atividade fí­sica no lazer e de deslocamento ativo. Por outro lado, os homens e os idosos apresentaram maior chance de serem mais ativos para a prática de atividade fí­sica. Conclusão: intervenções para incrementar a prática de atividade fí­sica em mulheres devem ser implementadas com vistas a prevenção e tratamento das doenças crônicas não transmissí­veis.
EFFECT OF AUSTENITIC GRAIN SIZE ON THE PHASE TRANSFORMATION OF A NOVEL 6.5% Cr STEEL FOR FORGED COMPONENTS
Authors: Di Schino Andrea
Published: June 2021

In this paper the effect of quenching and tempering (Q&T) thermal treatment on mechanical properties of a novel 6.5% Cr steel for forged components is studied. The main innovation is in the increased hardenability following the higher Cr content with respect to the more common 5% Cr steel allowing to lower the content of other chemical elements aimed to achieve the target mechanical properties. Following to the high intrinsic hardenability of such steel based on the Cr content a poor effect of prior austenite grain size should be expected after quenching. Aim of this work is to evaluate such effect and to analyse the dependence of mechanical properties on it.

Authors: Hong Dang Hue Thi , Thi Thuy Pham , Minh Ngung Dao , Quang Pham , Shchukin Valery Y.
Published: June 2021

A magnesium alloy AZ31 as plate of dimensions (60 x 60 x 3) mm has been constrained groove pressed (CGP) four deformation passes (16 pressings) at 250 oC by simulation and experiments. On the basis of the analysis of calculation results about the deformation distribution in the alloy AZ31 workpieces, the mechanism for its microstructure evolution during the severe plastic deformation (SPD) process was partly clarified. On the other hand, deformation heterogeneity distribution developed in the workpieces by applying CGP caused the evolution of a non-uniform microstructure. The TEM microstructure analysis results provided clear evidence that across the plate both the banded deformed microstructure where dislocation cell structure and/or partially or fully recovered polygonized subgrain microstructure are present. The recovering dynamic and local polygonization process contributes significantly to the formation of ultra-fine materials (UFG) microstructure.

Published: June 2021

В статье рассмотрен вопрос идентифицируемости математической модели кинетики химической реакции. В процессе решения обратной задачи по оценке параметров модели, характеризующих процесс, нередко возникает вопрос неединственности решения. На примере конкретной реакции продемонстрирована необходимость проводить анализ идентифицируемости модели перед проведением численных расчетов по определению параметров модели химической реакции.

The identifiability of the mathematical model of the kinetics of a chemical reaction is investigated in the article. In the process of solving the inverse problem of estimating the parameters of the model, the question arises of the non-uniqueness of the solution. On the example of a specific reaction, the need to analyze the identifiability of the model before carrying out numerical calculations to determine the parameters of the reaction model was demonstrated.

Authors: Кузнецова Е.В.
Published: June 2021

При моделировании системы управления минерально-сырьевым комплексом региона необходимо учитывать влияние рисков на реализуемость горного проекта, как элементов внешней среды. В работе выполнено моделирование системы управления минерально-сырьевым комплексом региона с учетом рисков горных проектов.

One of the most important state tasks in the management system of the mineral resource complex, both at the national and regional levels, is to ensure the reproduction of mineral resources. The solution of this problem can be modeled using the theory of control of active systems, which, of course, can be attributed to the mineral resource complex. When modeling the management system of the mineral resource complex of the region, it is necessary to take into account the impact of risks on the feasibility of a mining project, as elements of the external environment. In this paper, the authors have modeled the management system of the mineral resource complex of the region, taking into account the risks of mining projects.

The preparation temperature influences the physicochemical nature and activity of nanoceria
Authors: Yokel Robert A , Wohlleben Wendel , Keller Johannes Georg , Hancock Matthew L , Unrine Jason M , Butterfield D Allan , Grulke Eric A
Published: June 2021

Cerium oxide nanoparticles, so-called nanoceria, are engineered nanomaterials prepared by many methods that result in products with varying physicochemical properties and applications. Those used industrially are often calcined, an example is NM-212. Other nanoceria have beneficial pharmaceutical properties and are often prepared by solvothermal synthesis. Solvothermally synthesized nanoceria dissolve in acidic environments, accelerated by carboxylic acids. NM-212 dissolution has been reported to be minimal. To gain insight into the role of high-temperature exposure on nanoceria dissolution, product susceptibility to carboxylic acid-accelerated dissolution, and its effect on biological and catalytic properties of nanoceria, the dissolution of NM-212, a solvothermally synthesized nanoceria material, and a calcined form of the solvothermally synthesized nanoceria material (ca. 40, 4, and 40 nm diameter, respectively) was investigated. Two dissolution methods were employed. Dissolution of NM-212 and the calcined nanoceria was much slower than that of the non-calcined form. The decreased solubility was attributed to an increased amount of surface Ce4+ species induced by the high temperature. Carboxylic acids doubled the very low dissolution rate of NM-212. Nanoceria dissolution releases Ce3+ ions, which, with phosphate, form insoluble cerium phosphate in vivo. The addition of immobilized phosphates did not accelerate nanoceria dissolution, suggesting that the Ce3+ ion release during nanoceria dissolution was phosphate-independent. Smaller particles resulting from partial nanoceria dissolution led to less cellular protein carbonyl formation, attributed to an increased amount of surface Ce3+ species. Surface reactivity was greater for the solvothermally synthesized nanoceria, which had more Ce3+ species at the surface. The results show that temperature treatment of nanoceria can produce significant differences in solubility and surface cerium valence, which affect the biological and catalytic properties of nanoceria.

Published: June 2021

The supernova remnant (SNR) 3C 397 is thought to originate from a Type Ia supernova (SN Ia) explosion of a near-Chandrasekhar-mass (M
Ch) progenitor, based on the enhanced abundances of Mn and Ni revealed by previous X-ray study with Suzaku. Here we report follow-up XMM-Newton observations of this SNR, conducted with the aim of investigating the detailed spatial distribution of the Fe-peak elements. We have discovered an ejecta clump with extremely high abundances of Ti and Cr, in addition to Mn, Fe, and Ni, in the southern part of the SNR. The Fe mass of this ejecta clump is estimated to be ∼0.06 M
⊙, under the assumption of a typical Fe yield for SNe Ia (i.e., ∼0.8 M
⊙). The observed mass ratios among the Fe-peak elements and Ti require substantial neutronization that is achieved only in the innermost regions of a near-M

∼ 5 × 109 g cm−3, significantly higher than typically assumed for standard near-M

Are the Magnetic Fields Radial in the Solar Polar Region?
Authors: Sun 孙旭 Xudong 东 , Liu 刘 Yang 扬 , Milić Ivan , Belén Griñón-Marín Ana
Published: June 2021

We investigate the orientation of the photospheric magnetic fields in the solar polar region using observations from the Helioseismic and Magnetic Imager (HMI). Inside small patches of significant polarization, the inferred magnetic field vectors at 1″ scale appear to systematically deviate from the radial direction. Most tilt toward the pole; all are more inclined toward the plane of sky compared to the radial vector. These results, however, depend on the “filling factor” f that characterizes the unresolved magnetic structures. The default, uninformative f ≡ 1 for HMI will incur larger inclination and less radial fields than f < 1. The observed trend may be a systematic bias inherent to the limited resolution.

De l’engagement armé à l’engagement humanitaire : trajectoires militantes, émotions et sentiments moraux dans la Syrie post-2011
Authors: Ruiz de Elvira Laura
Published: June 2021

L’articulation des émotions et des sentiments moraux avec les logiques d’engagement est désormais bien documentée, en revanche, elle l’est moins avec les processus de désengagement et de démobilisation. Ce sont ces deux articulations interdépendantes que j’explore dans le contexte syrien post-mars 2011, marqué par une « crise révolutionnaire » qui a débouché sur une guerre civile internationalisée toujours en cours. Pour ce faire, je m’appuie sur une enquête de terrain effectuée en 2019 à Gaziantep (Turquie) au cours de laquelle j’ai conduit une série d’entretiens biographiques auprès de six anciens combattants reconvertis dans l’action humanitaire. Suivant une perspective interactionniste et de carrière, j’interroge les parcours de ces anciens combattants et l’expression de leurs émotions et sentiments moraux. J’analyse leur imbrication avec des formes de légitimation et de justification de l’action et avec des références axiologiques dans la (re)présentation du conflit, de la cause et du militantisme. Ce faisant, je mets en lumière la centralité des registres de la corruption, de l’injustice, de la responsabilité et de la culpabilité, ainsi que l’existence d’un continuum entre l’engagement révolutionnaire, armé et humanitaire.

Cette présentation a pour objectif de partager et discuter nos premières observations de cette période inédite. La crise de la Covid-19, par la singularité de sa temporalité et de sa portée multidimensionnelle, nous invite à une problématisation spécifique. Situation traumatogène qui amène à s’interroger, dans un bref après-coup, sur sa dimension traumatique ou non. Si oui, quel type de trauma. Situation qui a également induit des modalités réactionnelles particulières, placées sous le sceau du paradoxe. Enfin, cette crise nous incite à réfléchir sur les ressources et opérateurs permettant de la traverser sans trop de dommages, dans le maintien d’une certaine continuité d’être.
L’adolescence, crise individuelle, familiale ou sociale ?
Authors: Ohayon Annick
Published: June 2021

De la Libération à la fin des années 1960, l’adolescence devient un sujet d’étude important pour les psychiatres, les psychologues et les psychanalystes, en lien avec le thème de la délinquance juvénile. Au centre de ces recherches, on trouve la notion de crise, issue des travaux du psychologue wallonien Debesse. Mais quel est le sens de cette crise ? Doit-elle nécessairement apparaître au cours du développement ? Quelles en sont les causes ? Individuelles ? sociales ? familiales ? Quels seraient les remèdes possibles ? L’auteure retrace quelques recherches de cette période qui visent à éclairer ces questions. Ce recul historique permet de s’interroger sur ce qui est permanent dans les difficultés des adolescents et sur ce qui est plus spécifique de la société contemporaine.
De toi(t) en toi(t) : une figure transdisciplinaire de l’adolescence « maudite » ?
Authors: Urgese Svetoslava , Ciccone Albert
Published: June 2021

Cet article porte sur l’approche transdisciplinaire au sein du travail d’équipe dans l’accompagnement d’adolescents aux parcours de vie difficiles. Ceux-ci sont rencontrés au sein d’une institution qui est un itep (institut thérapeutique éducatif et pédagogique). La réflexion émerge de la rencontre clinique d’un jeune et de l’observation des liens à l’équipe qui l’accompagne. Sont abordés les caractéristiques, les logiques et les effets d’un accompagnement transdisciplinaire pour ces adolescents. La diffraction transférentielle et la polyphonie groupale soutiennent les processus de remembrance, pour les jeunes comme pour les professionnels, dans l’espoir de retisser et réparer l’histoire « maudite » de ces adolescents.

En décembre 2020 sortait en France le documentaire de Sébastien Lifshitz Petite fille , adulé par les médias. L’auteure soulève ici les questions qu’a suscitées pour elle le visionnage de ce film, dans une perspective critique. Puis, en le comparant à un autre film français très remarqué au moment de sa sortie, Les garçons et Guillaume, à table ! , elle explique, depuis la théorie et la clinique psychanalytiques, la complexité du processus de sexuation par lequel un enfant, puis un adolescent, devient « garçon » ou « fille », puis « homme » ou « femme ». Ce qui pose la question de l’accompagnement des enfants et des adolescents, ainsi que des familles, qui sont traversés, et parfois bouleversés, par ces problématiques.
La construction d’une posture de clinicienne… à travers l’accueil et l’élaboration d’un éprouvé socialement impensé : le deuil périnatal
Authors: Gaspari Daphné
Published: June 2021

Cet article propose, par le biais d’une écriture clinique articulant le registre du vécu et celui de la réflexivité, de montrer l’importance de la posture clinique dans l’accueil et l’accompagnement de sujets confrontés à une situation difficilement pensable au niveau social, celle de la perte d’un enfant au cours d’une grossesse. L’invisibilité des enfants nés sans vie, la difficile considération du deuil périnatal, la prégnance des normes et représentations sociales qui entourent la naissance sont autant d’éléments à réinterroger pour accroître la capacité des professionnels et de l’entourage dans l’accompagnement de parents endeuillés. L’auteure montre également comment un événement biographique particulièrement impactant peut être un point de contact essentiel avec la nécessité d’une approche clinique permettant d’élaborer à partir de son propre vécu.
Stochastic perturbation of a cubic anharmonic oscillator
Authors: Bernardi Enrico , Lanconelli Alberto
Published: June 2021

We perturb with an additive noise the Hamiltonian system associated to a cubic anharmonic oscillator. This gives rise to a system of stochastic differential equations with quadratic drift and degenerate diffusion matrix. Firstly, we show that such systems possess explosive solutions for certain initial conditions. Then, we carry a small noise expansion's analysis of the stochastic system which is assumed to start from initial conditions that guarantee the existence of a periodic solution for the unperturbed equation. We then investigate the probabilistic properties of the sequence of coefficients which turn out to be the unique strong solutions of stochastic perturbations of the well-known Lamé's equation. We also obtain explicit expressions of these in terms of Jacobi elliptic functions. Furthermore, we prove, in the case of Brownian noise, a lower bound for the probability that the truncated expansion stays close to the solution of the deterministic problem. Lastly, when the noise is bounded, we provide conditions for the almost sure convergence of the global expansion.
On a class of differential quasi-variational-hemivariational inequalities in infinite-dimensional Banach spaces
Authors: Treanţă Savin
Published: June 2021

A class of differential quasi-variational-hemivariational inequalities (DQVHI, for short) is studied in this paper. First, based on the Browder's result, KKM theorem and monotonicity arguments, we prove the superpositionally measurability, convexity and strongly-weakly upper semicontinuity for the solution set of a general quasi-variational-hemivariational inequality. Further, by using optimal control theory, measurability of set-valued mappings and the theory of semigroups, we establish that the solution set of (DQVHI) is nonempty and compact. This kind of evolutionary problems incorporates various classes of problems and models.

We show that, for any nonsingular projective 4-fold $ V $ of general type with geometric genus $ p_g\geq 2 $, the pluricanonical map $ \varphi_{33} $ is birational onto the image and the canonical volume $ {\rm Vol}(V) $ has the lower bound $ \frac{1}{480} $, which improves a previous theorem by Chen and Chen.
Game value for a pursuit-evasion differential game problem in a Hilbert space
Authors: Badakaya Abbas Ja'afaru , Halliru Aminu Sulaiman , Adamu Jamilu
Published: June 2021

We consider a pursuit-evasion differential game problem with countable number pursuers and one evader in the Hilbert space \begin{document}$ l_{2}. $\end{document} Players' dynamic equations described by certain \begin{document}$ n^{th} $\end{document} order ordinary differential equations. Control functions of the players subject to integral constraints. The goal of the pursuers is to minimize the distance to the evader and that of the evader is the opposite. The stoppage time of the game is fixed and the game payoff is the distance between evader and closest pursuer when the game is stopped. We study this game problem and find the value of the game. In addition to this, we construct players' optimal strategies.
Local Kalman rank condition for linear time varying systems
Authors: Maarouf Hamid
Published: June 2021

In this paper, we study some non-negative integers related to a linear time varying system and to some Krylov sub-spaces associated to this system. Such integers are similar to the controllability indices and have been used in the literature to derive results on the controllability of linear systems. The purpose of this paper goes in the same direction by studying the local behavior of these integers especially nearby instants in the time interval with some maximal rank condition and then apply them to get some results which generalize the mentioned existing results.

Published: June 2021

Endophytes represent microorganisms residing within plant tissues without typically causing any adverse effect to the plants for considerable part of their life cycle and are primarily known for their beneficial role to their host-plant. These microorganisms can in vitro synthesize secondary metabolites similar to metabolites produced in vivo by their host plants. If microorganisms are isolated from certain plants, there is undoubtedly a strong possibility of obtaining beneficial endophytes strains producing host-specific secondary metabolites for their potential applications in sustainable agriculture, pharmaceuticals and other industrial sectors. Few products derived from endophytes are being used for cultivating resilient crops and developing non-toxic feeds for livestock. Our better understanding of the complex relationship between endophytes and their host will immensely improve the possibility to explore their unlimited functionalities. Successful production of host-secondary metabolites by endophytes at commercial scale might progressively eliminate our direct dependence on high-valued vulnerable plants, thus paving a viable way for utilizing plant resources in a sustainable way.

In the present paper, some necessary and su?cient optimality conditions for a convex optimization problem over inequality constraints are presented which are not necessarily convex and are based on convex intersection of non-necessarily convex sets. The oriented distance function and a characterization of the normal cone of the feasible set are used to obtain the optimality conditions. In the second part of the paper, a non-linear smooth optimization model for customer satisfaction in automotive industry is introduced. The results of the first part are applied to solve this problem theoretically.

Authors: Marakovits Scott J.
Published: June 2021

The purpose of this chapter is to identify and offer solutions based on four barriers to facilitating 21st century competencies through digitalization. The first barrier includes the technological challenges faced by families, including devices and reliable broadband internet. The second barrier explores the training and support needed by teachers in implementing digital tools and instructional technology. The third barrier is a pedagogical shift from teacher-centered to student-centered teaching and learning, especially in remote environments where this approach is needed for student engagement. The fourth barrier is training for parents and families to become familiar with the technology and digital tools that their children are using. Practical solutions backed by research are presented by the author for consideration by teachers, administrators, and the school community. Prompts for reflection and discussion based on identified barriers and real-life examples are presented by the author at the conclusion of the chapter.

Authors: Zitko Peter Anthony
Published: June 2021

The purpose of this chapter is to describe educational barriers confronting incarcerated college students in the age of digitalization. This chapter will also explore how to mitigate barriers to developing 21st century competencies. Many incarcerated college students are academically disenfranchised due to the lack of access to essential modern learning modalities for traditional college students. Failure to provide incarcerated students with adequate 21st century competencies may impede their successful reintegration into society.
The Scope of Colonial Writing in Enhancing Sri Lankan Cultural Diplomacy
Authors: Dissanayake Achala K.
Published: June 2021

Culture is a necessary ingredient in the definition of a nation. Cultural diplomacy is the use of cultural values and norms by nations in the processes of strengthening, revising, or redefining their national identities both within the country and externally. Works of literature are among the many tools of cultural diplomacy. As a source of soft power widely used by countries in their relationships with foreign nations, cultural diplomacy has been criticized from a postcolonial perspective for contributing to the homogenization of cultures and nations. This paper argues that, where Sri Lankan cultural diplomacy is concerned, certain literary representations of Sri Lanka as was seen through the colonizer's gaze could be used in order to construct national culture, strengthen national identity and portray a more holistic picture of Sri Lanka to the world.
Effect of Latency for a Reputation Based Trust Model of Peer-to-Peer Content Distribution Networks
Authors: Ekanayake Shanika
Published: June 2021

Over the last few decades, pioneering tools and techniques for successful communication have been invented with the remarkable evolution of attention in information sharing and knowledge. As a result, sophisticated communication environments are invented in order to have a better communication and information delivery. Internet has become the most outstanding discovery among extensive communication technologies with gigantic volumes of information. Content Delivery Networks (CDNs) have been introduced for rich and rapid data delivery over the Internet. Hence the capability enhancements of CDN nodes have been improved the reputation and the scope. Various challenges appeared on those open and autonomous network architectures in order to achieve confidentiality, authenticity and availability security dimensions. This paper resolves trust issues between content delivery nodes on Peer to Peer (P2P) network infrastructures by an enhancing trust algorithm of my previous research “de-centralized reputation based trust model for peer to peer content delivery networks” (Shanika Ekanayake, 2014). Moreover, performance comparison between previous trust algorithm and the enhanced trust algorithm is evaluated through the ns-2 simulator.
Strategic Marketing Approach in Container Shipping: Application of Ten S Model
Authors: Edirisinghe Lalith
Published: June 2021

The application of strategic marketing theories is rather difficult due to the complexities in demand and supply factors in the shipping industry. Shipping is a derived demand of international trade. The supply of shipping also has its exclusiveness leading to very complicated outcomes. Given the fact that shipping has more services characteristics than that of a product the key fundamentals such as perishability, intangibility, non-separability, and heterogeneity make it further complicated. This paper attempts to systematically apply the Ten S marketing model because it is expected that the model could be applied in highly complicated marketing environments.

Background: Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are significant public health issues in the world, but the epidemiological data pertaining to HAP/VAP is limited in Korea. The objective of this study was to investigate the characteristics, management, and clinical outcomes of HAP/VAP in Korea.Methods: This study is a multicenter retrospective cohort study. In total, 206,372 adult patients, who were hospitalized at one of the 13 participating tertiary hospitals in Korea, were screened for eligibility during the six-month study period. Among them, we included patients who were diagnosed with HAP/VAP based on the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) definition for HAP/VAP.Results: Using the IDSA/ATS diagnostic criteria, 526 patients were identified as HAP/VAP patients. Among them, 27.9% were diagnosed at the intensive care unit (ICU). The cohort of patients had a median age of 71.0 (range from 62.0 to 79.0) years. Most of the patients had a high risk of aspiration (63.3%). The pathogen involved was identified in 211 patients (40.1%). Furthermore, multidrug resistant (MDR) pathogens were isolated in 138 patients; the most common MDR pathogen was Acinetobacter baumannii. During hospitalization, 107 patients with HAP (28.2%) had to be admitted to the ICU for additional care. The hospital mortality rate was 28.1% in the cohort of this study. Among the 378 patients who survived, 54.2% were discharged and sent back home, while 45.8% were transferred to other hospitals or facilities.Conclusion: This study found that the prevalence of HAP/VAP in adult hospitalized patients in Korea was 2.54/1,000 patients. In tertiary hospitals in Korea, patients with HAP/VAP were elderly and had a risk of aspiration, so they were often referred to step-down centers.

The respiratory epithelium forms the first line of defense against inhaled pathogens and acts as an important source of innate cytokine responses to environmental insults. One critical mediator of these responses is the IL-1 family cytokine IL-33, which is rapidly secreted upon acute epithelial injury as an alarmin and induces type 2 immune responses. Our recent work highlighted the importance of the NADPH oxidase dual oxidase 1 (DUOX1) in acute airway epithelial IL-33 secretion by various airborne allergens associated with H2O2 production and reduction-oxidation–dependent activation of Src kinases and epidermal growth factor receptor (EGFR) signaling. In this study, we show that IL-33 secretion in response to acute airway challenge with house dust mite (HDM) allergen critically depends on the activation of Src by a DUOX1-dependent oxidative mechanism. Intriguingly, HDM-induced epithelial IL-33 secretion was dramatically attenuated by small interfering RNA– or Ab-based approaches to block IL-33 signaling through its receptor IL1RL1 (ST2), indicating that HDM-induced IL-33 secretion includes a positive feed-forward mechanism involving ST2-dependent IL-33 signaling. Moreover, activation of type 2 cytokine responses by direct airway IL-33 administration was associated with ST2-dependent activation of DUOX1-mediated H2O2 production and reduction-oxidation–based activation of Src and EGFR and was attenuated in Duox1−/− and Src+/− mice, indicating that IL-33–induced epithelial signaling and subsequent airway responses involve DUOX1/Src–dependent pathways. Collectively, our findings suggest an intricate relationship between DUOX1, Src, and IL-33 signaling in the activation of innate type 2 immune responses to allergens, involving DUOX1-dependent epithelial Src/EGFR activation in initial IL-33 secretion and in subsequent IL-33 signaling through ST2 activation.
