Published: July 2022

Background: Time spent on social networking sites and the images trolling may have variable effects on physical and mental well-being including changes in perception of body image (BI) and dietary behavior. Particularly, junk food photos are highly popular on Instagram. Exposure to this type of content may have a negative effect on eating behavior by potentially setting an altered standard for food quantities and preferences. Aim: The present study aimed to assess the effects of junk food-related content exposure on Instagram on BI dissatisfaction (BID), state BI, mood, and cravings. Method: A randomized crossover experimental design was used. Sixty-three university students filled out an online baseline survey assessing baseline BID, physical activity, healthy eating, and social media use. They were then asked to browse either a control Instagram account feed or junk food account for 15 minutes, after which they filled out a short survey on state BI, mood, and cravings. After a washout period of 1 week, participants were exposed to the other type of account and asked to fill out the same short survey. A focus group of 9 participants was conducted after data collection to understand the level of awareness of participants on the effect of social media exposure on BID, mood, and cravings. Results: Results indicated significantly higher scores of state BID, reported feelings of stress, sadness, hunger, and exhaustion as well as higher salty, savory, and fatty food cravings when participants were exposed to junk food content as compared to control content exposure. Participants reported higher cravings of junk food (burger and pizza) and lower cravings of healthy foods (whole grain turkey bagel and chicken salad) when exposed to the junk food content as compared to the control content. Regression analyses revealed that cravings for junk food was mediated by state BID and feelings of hunger after being exposed to junk food content on Instagram. Qualitative analysis revealed that young adults are aware that junk food content can increase their cravings and sometimes cause them to feel negatively about their body. Conclusion: The present study revealed that SNS junk-food related content may negatively affect BID as well as mood and cravings. The results shed light on the need for interventions to increase community awareness such as social media literacy programs that provide technical, cognitive, and emotional competencies for mindful SNS use and reduce the negative impact of certain types of social media content.
Palladin Regulates Invadopodia Formation in Glioblastoma. (c2021)
Authors:   ,   Lebanese American University, Abi Khalil Elie
Published: July 2022

Glioblastoma multiforme (GBM), also referred to as glioblastoma is a rapidly dividing glioma that develops from astrocytes and oligodendrocytes (glial cells that nourish the brain). GBM can also be classified as a grade IV astrocytoma, which represents the most invasive, rapidly growing, and metastatic type of glial tumors. Our lab has been primarily interested in identifying and studying pathways relevant to the progression of this disease through which we recently determined that hypoxia and EGF stimulation contribute to VEGF expression via the differential regulation of the PI3K/Rho-GTPase and MAPK signaling pathways. Palladin is a relatively novel actin-associated phosphoprotein that has been reported to be implicated in a variety of cancers such as pancreatic adenocarcinoma and ductal carcinoma of the breast. It has also been reportedly involved in the development of invadopodia, dorsal ruffles, podosomes, focal adhesions, and has been shown to be involved in regulating the expression of the Rho-GTPases, Cdc42 and Rac1. More recently, palladin has been shown to alter actin dynamics in podocytes as well as replace the Arp2/3 complex during Listeria infections, contributing to the assembly of actin-based structures. In this study, we used a palladin knockdown model in order to assess invadopodia formation in glioblastoma cell line U87. The results show an increase in invadopodia as seen by TKS4 and TKS5 staining as well as a decrease in Cdc42 activity following palladin knockdown. We have also been able to demonstrate a novel role for palladin in the expression of Rac1. This study serves to characterize palladin within the context of invadopodia formation and as such we have been able to identify potential crosstalk between palladin and Rho GTPases such as Cdc42 and Rac1.
Soil-water characteristic curve of polypropylene fibrereinforced sandy soil
Authors: Castro Cíntia , Soares Anderson , Aguiar Marcos
Published: July 2022

Fibre reinforcement is considered a good alternative for improving the geotechnical properties of soil. However, studies that investigate its behaviour, accounting for the unsaturated condition, and the hydraulic behaviour of soil mixtures with fibre, are limited. Therefore, the current study evaluates the impact of the inclusion of polypropylene fibres on the hydraulic behaviour of soil through geotechnical characterisation, scanning electron microscopy (SEM), macroporosity and microporosity tests, and filter paper tests. The soil-water characteristic curve (SWCC) of different mixtures of fibre-reinforced soil was adjusted by the models enshrined in the literature, using polypropylene fibres of length 6 mm, diameter 18 μm, and fibre contents 0.25% (SF025), 0.75% (SF075), 1.0% (SF100), and 1.25% (SF125) relative to the dry weight of the soil. The results indicated a transition from unimodal to bimodal shape in the SWCC for the polypropylene fibre-reinforcement, suggesting that their inclusion altered the soil structure. The same bimodal behaviour of SWCC was observed in all reinforced samples that produced similar values of air-entry suction and residual volumetric water content, but with increased water retention for the same level of suction for higher fibre content. The results of the tension table test indicated an increase in the volume of macropores with an increase in fibre content and a decrease in micropore volumes. These results agree with the compaction tests, which showed a decrease in the dry maximum density with an increased fibre content, whereas the optimum water content increased.

ESTENOSE MITRAL CALCÍFICA (CALCIFICAÇÃO DO ANEL MITRAL)
Authors:   Instituto Dante Pazzanese de Cardiologia., Minuzzo Luiz , Magro Kroll Roberto Tadeu ,   Instituto Dante Pazzanese de Cardiologia.
Published: July 2022

A calcificação do anel mitral (MAC) é uma doença complexa e multifatorial, que pode acarretar tanto estenose quanto insuficiência mitral e que necessita de avaliação detalhada para seu diagnóstico, passando pelo estudo de uma equipe multidisciplinar para decisão acerca da melhor conduta a ser estabelecida em cada caso. Atualmente, a avaliação por multimodalidades de imagem é fundamental para o estudo dos detalhes anatômicos e estratificação da gravidade da doença, bem como para auxiliar na definição estratégica que pode se limitar à terapêutica clínica exclusiva ou envolver medidas intervencionistas. A intervenção é desafiadora, pois se aplica a um perfil de pacientes de maior riscopré--intervenção, além da complexidade anatômicatípica da doença. A intervenção pode se dar por cirurgia convencional, porém com alto risco de complicações graves associadas, sendo a disjunção atrioventricular a mais temida. Há também os procedimentos per-cutâneos quando realizado o acesso valvar via transeptal e os híbridos, que necessitam de pequena toracotomia e utilização de dispositivos originalmente desenhados para a intervenção percutânea valvar aórtica. Recentemente, foram realizados estudos sobre o desenvolvimento de próteses dedicadas ao cenário de intervenção valvar na MAC, que nas fases iniciais contemplaram um número limitado de pacientes com insuficiência mitral. Portanto, novos estudos necessitam ser realizados, com o desenvolvimento de novas técnicas cirúrgicas e dispositivos dedicados à MAC, objetivando a redução das complicações associadas que ainda são muitas e avaliação da melhora dos sintomas, o que não é fácil numa doença que envolve pacientes com múltiplas comorbidades e cujos sintomas não ocorrem necessariamente apenas pela disfunção valvar.

A estenose aórtica (EAo) degenerativa apresenta aumento progressivo da prevalência associada ao aumento global da expectativa de vida e envelhecimento populacional. A intervenção valvar, seja cirúrgica ou transcateter, é a única estratégia de tratamento as-sociada à redução de mortalidade em pacientes portadores de EAo e, por isso, o ponto chave é o momento de indicação da intervenção valvar. O desafio atual é a indicação cada vez mais precoce visando pacientes ainda assintomáticos e com isso melhorando significativamente o prognóstico relacionado à doença valvar. O método de intervenção pode ser cirúrgico ou via transcateter e cada uma possuindo indicações e contraindicações específicas. Este capítulo tem como objetivo resumir o raciocínio clínico que norteia a tomada de decisão para proposta de intervenção, assim como abordar questões inerentes à abordagem cirúrgica do paciente portador de valva aórtica bicúspide (ou bivalvularizada), aortopatia associada e estratégias transcateter.

A presente pesquisa tem como objetivo a descrição de aspectos da morfologia Manxineru com foco especial na estrutura dos nomes e a relação deles com outras classes de palavras. A língua Manxineru conta com aproximadamente 1.106 falantes, que vivem em 12 aldeias na Terra Indígena Mamoadate, localizada no sudoeste do estado do Acre, Brasil. Para este trabalho, foi de fundamental importância a colaboração de três falantes nativos da língua Manxineru, que proporcionaram a construção e revisão de um banco de dados, que contém mais de 1700 itens lexicais. Com esses dados, foi possível, na perspectiva da linguística descritiva, elaborar o presente artigo, tendo como suporte teórico trabalhos de Couto (2012) e (2016), Hanson (2010), Matteson (1954), Ramirez (2001), Rodrigues (2002) entre outros. Para este artigo, foi possível descrever algumas características da morfologia dos nomes do Manxineru, como, por exemplo, a existência de marcador de aspecto e de gênero nos nomes; a obrigatoriedade da concordância de gênero entre nomes e adjetivo; a presença de um mediador de posse; além de verificarmos alguns dos fenômenos característicos das línguas Aruák, que são a distinção entre nomes absolutos e nomes relativos e a presença produtiva dos prefixos possessivos e pessoais.
Considerações sobre variação linguística na língua Terena
Authors: Teixeira Lovania Roehrig , De Oliveira Caroline Pereira , Vertelino Marques Kassiely Odeth
Published: July 2022

Este artigo procura discutir o fenômeno da variação linguística na língua Terena a partir de pressupostos da Sociolinguística (LABOV, 2008; BAGNO, 2015). A discussão parte de exemplos coletados em três aldeias Terena situadas em dois municípios de Mato Grosso Sul: Aldeias Lagoinha e Bananal (Aquidauana) e Aldeia Cachoeirinha (Miranda) a partir de conversas espontâneas com os residentes. Uma pesquisa nesses moldes se justifica pela importância de compreender que o fenômeno da variação linguística e a existência de variedades linguísticas diferentes dentro de uma mesma língua não é um problema, e sim é um resultado natural da riqueza linguística, cultural e social de seus falantes. Assim, evitam-se conflitos sociolinguísticos entre os falantes dessa língua natural e a perpetuação de preconceito linguístico em relação a uma ou outra comunidade de fala. A partir das entrevistas, verificou-se que nas três aldeias Terena ocorre o fenômeno da variação linguística. Especificamente, encontraram-se exemplos de variação diastrática, decorrente da faixa etária dos falantes de Terena e, internamente, observou-se variação de natureza lexical, isto é, referente a nomes que designam objetos. A partir disso, verificou-se que há também variação linguística na língua Terena, fenômeno orgânico em todas as línguas naturais e, por isso, não há variedade de Terena mais adequada ou mais original, pois todas elas possibilitam a interação entre os falantes dessa comunidade de fala.

The article focuses on the challenges of improving the energy efficiency when using the solar energy for electrical power generation. The key point is that improvement of the energy efficiency in application of this method depends on enhancement of theoretical knowledge on physical phenomena and regularities in technical devices. The objective of this research is to clarify the cause-and-effect relations and to explain regularities of physical phenomena in devices that convert solar power into electric energy in terms of fundamental axioms of the quantum theory in molecular systems, which would open up the possibilities to enhance the energy efficiency of solar power engineering. The paper analyzes the notions that are common in the scientific and educational literature and are related to electric current, free and superfluous electrons in atoms, and the motion of charged particles under the action of electric current. The scientific novelty consists in conceptualization of scientific statements in the fields of physics, electrical engineering and chemistry. A new concept of the energy phenomena in multilayer structures of semiconductor-based devices for conversion of solar radiation into the electric current has been formed for the first time ever. A schematic diagram of electric power generation upon solar irradiation of these devices is presented. The electric current in a closed circuit is the total solar energy absorbed by the valence electrons of the device's semiconductors, which they emit in a concentrated manner within a closed electric circuit. The practical value of the new knowledge lies in improving the professional competences and enhancing the energy efficiency of technological devices used to convert solar energy into electric current.

The article provides an overview of the major global manufacturers of mixing and charging equipment, as well as a presentation of several Russian companies. As the consumption of industrial explosives increases, the share of equipment that produces these substances is also growing. The purpose of this article is to identify the competitive advantages and the role of import substitution in Russia. Before 2014, most of the fleet in all mining companies was made up of imported equipment. Given the political circumstances after 2014, the situation in the country has changed, and the Russian mining industry began to replace foreign machinery with domestic mixing and charging machines, which are not inferior in quality, but more competitive in price. There are already more than 10 manufacturers of mixing and charging equipment in Russia, including the following companies: AZOTTECH LLC (Berezniki), NIPIGORMASH JSC (Yekaterinburg), Research Institute of Mechanization (Krasnoarmeysk), SpetsTransMash LLC (Novokuznetsk) and others. The article also presents a comparative analysis of two lines of mixing and charging machines manufactured by AZOTTECH LLC, i.e. the BAZA and the TECHNO families.

The results of investigations of the treatment conditions influence on the regularities of structural-phase transformations, microstructure and mechanical properties of heat-resistant low-activation 12 % chromium ferritic-martensitic steel EK-181 are summarized. The physical factors responsible for increasing the yield strength of steel, the relationship of microstructure features with strength and plastic properties are revealed. The regularities of plastic deformation of steel are established. The modes of step-by-step heat treatment (SHT) and high-temperature thermomechanical treatment (HTMT) are presented, which lead to the formation of structural states with high values of dispersion and volume fraction of nanoscale particles V(C, N), dislocation density and internal stresses. These modes provide a significant (by ≈ 20 %) increase in the strength properties of steel in a wide (from –196 to 800 °C) temperature range, while maintaining a sufficient reserve of plasticity and increasing its thermal stability, compared with the traditional heat treatment mode (THT).
Cognitive Understanding of the Semantic Field «Йәш» / “Age” in the Bashkir Language (by the Material of Monosyllabic Stems)
Authors: Nigamatova Albina Alfredovna
Published: July 2022

The paper addresses the issues of the cognitive approach in the study of the semantic field «Йәш» / “Age” in the Bashkir language and in a number of closely related languages of the Urals-Volga region. The research aims to develop a comprehensive interpretation of the conceptual field «Йәш» / “Age” not only as a separate concept but also as a phenomenon in the cognitive system of the Bashkir language and a number of related languages of the Urals-Volga region, as well as to identify coinciding monosyllabic stem types. The research is novel in that it is the first to identify stems of unexplored Bashkir dialect vocabulary associated with the conceptual field “Age”. As a result, similar monosyllabic stems belonging to the semantic field «Йәш» / “Age” in closely related languages have been found, which allowed the researcher to draw certain conclusions regarding the ethnogenetic connections of languages and individual dialects of the region.

Authors: Lutfullina Gulnara Firdavisovna
Published: July 2022

The aim of this article is to identify the specific features of the case and prepositional forms of the substantives of the aspectual semantics of the initial phase in the Russian and English languages. The scientific novelty of the study lies in the fact that for the first time the features of the adverbial modifiers of temporal-aspectual semantics are considered including the substantives of the initial phase in various case and prepositional forms. As a result, it has been proved that in the Russian language, the case form of the substantive «начало» (“beginning”) in adverbial modifiers strictly correlates with the prepositional one and is limited to four cases. In English, the prepositional form of the substantives “beginning”, “start” as a part of adverbial modifiers is limited to one case and is compensated by the variety of the prepositional one.
Locative Meanings of Words with ‘пурэбэ’ and ‘албэ’ Components in the Tundra Yukaghir Language
Authors: Kurilova Ladina Gavrilovna
Published: July 2022

The aim of the study is to determine the semantic, structural and morphological features and functioning of nominal formations with the affix -бэ indicating the location: пурэбэ ‘upper part of something’ and албэ ‘lower part of something’. The scientific novelty is due to the fact that for the first time in the studies of the Yukaghir language, complex formations with the affix -бэ, expressing locative semantics, have been analysed. As a result, it has been revealed that the nominal components пурэбэ ‘upper part of something’ and албэ ‘lower part of something’ convey the semantics of the upper and lower locations of the earth’s space layers, nature and the surrounding world and the localization of the upper and lower parts, positions of items, subjects, objects.

Authors: Svetaylov Boris Vladimirovich
Published: July 2022

The aim of this study is to determine the linguistic and socio-cultural features of hedging in the text of an English-language scientific article on economic topics. The paper provides a definitional analysis of the notion “hedging”, defines its functions in a scientific text from the position of rhetorical potential and perception of a text by recipients, and notes the pragmatic potential of hedging as an argumentation tool within the framework of scientific discourse. The scientific novelty of the study lies in a comprehensive analysis of hedging markers within the framework of economic articles, both in terms of linguistic and socio-cultural characteristics. As a result, it has been proved that hedging markers are of key importance in the text of a scientific article on economic topics, being an effective method of argumentation, interaction with a reader and obscuration of epistemic responsibility by the author.
