Fake news, desinformação e necessidade de formar leitores críticos
Authors: Leurquin Eulália Vera Lúcia Fraga , Leurquin Chloé
Published: December 2021

Este artigo apresenta uma discussão sobre fake news e desinformação, considerando efeitos desses fenômenos na sociedade contemporânea e atentando para a necessidade de formar leitores críticos, conscientes da exigência de conhecer a origem das informações. Nosso objetivo é mostrar como as fake news e a desinformação se originam, se constituem e propagam seus efeitos na sociedade. Os dados analisados estão situados em dois momentos importantes no país: o período das eleições a Presidente da República do Brasil, em 2018, e o segundo ano da pandemia decorrente da Covid-19, em 2021. Analisamos o contexto de produção das fake news e da desinformação, considerando o contexto de produção, o mundo físico e o sociossubjetivo, bem como os mecanismos enunciativos (BRONCKART, 1999, 2019), buscando argumentar a favor da formação de leitores críticos (KLEIMAN; SANTOSMARQUES, 2020; LEURQUIN, 2001, 2014; LEURQUIN; LEURQUIN, 2021; BRASIL, 2017).

Authors: Martins Gustavo , Gomes Genildo , Conceição Júlia Luiza , Marques Leonardo , Da Silva Dan , Castro Thais , Gadelha Bruno , De Freitas Rosiane
Published: December 2021

The use of mobile devices, especially smartphones, is widespread across all social strata and age groups, helping to ensure faster access from anywhere, data collection, and more regular and frequent control to aid urban, environmental, and social management. In this scenario, the entertainment industry has benefited from this powerful individual technological resource in cultural and sporting events. In this way, this work presents a proposal for interaction and engagement in entertainment events in a more prosperous and more technological way, through the development of a collaborative and competitive mobile-­web crowd game, intended for enhancing interaction between the crowd and as a unified group, whether physically co-­located or online. The application, called Bumbometer, uses motion sensors during an interactive dynamic with the crowd applying concepts from Mobile Crowd Sensing and User eXperience. We conducted two experimental studies to evaluate the proposed technology, the first in a real scenario of a folk cultural festival and the second in a controlled environment, simulating an event considering a scenario in which users were geographically distant. The results indicate that people feel immersed and engaged during the interaction through the proposed game, which reinforces the statement that the game meets an increasingly growing need to use technologies to ensure more significant interaction and audience immersion at crowd entertainment events, a creative and far­-reaching form.

Environmental Particulate Air Pollution Exposure and the Oxidative Stress Responses: A Brief Review of the Impact on the Organism and Animal Models of Research
Authors: Brendler Goettems Fiorin Pauline , Stela Ludwig Mirna , Nunes Frizzo Matias , Gomes Heck Thiago
Published: December 2021

Particulate matter (PM) is a mixture of solid particles and liquid droplets found in the air, and it is one of the most harmful air pollutants. When inhaled, it affects the pulmonary system, cardiovascular systems, and other tissues. The size, composition, and deposition of PM, mainly related to fine and ultrafine particulate matter, are factors that determine the harmful effects of exposure to particles. Among the main effects is the inducer of ROS production, and consequently oxidative tissue damage in target organs and other responses, mediated by inflammatory cytokines and cellular stress response. The main pathway through which particles are potent mediators of oxidative stress is the damage caused to DNA and lipid molecules, whereas the pro-inflammatory response involves an immune response against PM, which in turn, it is related to cell stress responses observed by heat shock proteins (HSPs) expression and release. Thus, the ability of an organism to respond to PM inhalation requires anti-oxidative, anti-inflammatory, and cellular stress defenses that can be impaired in susceptible subjects as people with chronic diseases as diabetes and obesity. In this chapter, we discuss the mechanistic aspects of PM effects on health and present some animal research models in particle inhalation studies.
The orthography of Resava in the Baranja Transcription of Dušan's Code
Authors: Antić Aleksandra
Published: December 2021

The paper examines the characteristics of the orthography of Resava in the Baranja Transcription of Dušan's Code, created at the beginning of the 16th century. The research included the following features: the writing of the grapheme x, the writing of the grapheme Q at the etymological place, the use of the grapheme J in front of j, the use of the ligature ] to mark the initial group [ja] and the use of the grapheme a to mark the aforementioned group after a vowel, the use of the graphemes e and j to mark the group [je] in all positions in the word, the use of the Greek letters, the latest punctuation system, and, lastly, the writing of the accents and spiritus lenis. A significant number of examples confirmed the use of the grapheme Q at the etymological place, the use of the grapheme J to mark the so-called reduced i, the use of the grapheme a to write the group [ja] after a vowel, the use of the comma and the full stop on the line on the bottom, as well as the writing of the accents and spiritus lenis. The research has also shown that the grapheme x was written in an isolated example, that the group [je] was primarily written by using graphemes j and e, which is in accord with the orthography of Resava, and, finally, that the rare use of the Greek letters is related to the Greek words. Therefore, it was concluded that the norms of the orthography of Resava were not consistently implemented in the Baranja Transcription of Dušan's Code. The research also confirmed the coexistence of Raška and Resava orthographic norms in some cases.
Possibilities of developing motivation for learning among students of the University of Priština with temporary headquarters in Kosovska Mitrovica
Authors: Davidović-Rakić Jelena , Đurić Igor
Published: December 2021

The paper strives to consider the intensity and structure of motivation for studying among undergraduates of the University of Priština in Kosovska Mitrovica, as well as to check whether there are differences in the intensity of intrinsic and extrinsic motivation among undergraduates of different faculties. In addition, drawing on the Theory of Self-Determination of Edward Deci and Richard Ryan, we were interested in the structure of motivation for studying in two sociocultural areas: Serbia and Croatia. The research was conducted during the summer semester of 2017 on the premises of five faculties. The Thomas-Miller scale was used to examine motivation for studying. The most intense individual motivator for studying is "I am studying, because I will be able to get / find a better job", and the presence of the intrinsic factor of motivation for studying is more pronounced. The research findings have indicated that all motivators are classified into two factors, intrinsic and extrinsic ones, and account for 51.40% of the variance of the observed measurement space. Our research obtained a different structure of factors, in relation to the research results in Croatia. Motivators "... because I simply have to" and "… because I will be able to get / find a better job" have replaced affiliation, in relation to the structure of factors obtained in the Croatian sample of respondents. Both observed factors of motivation for studying are the most intense among undergraduates of the Faculty of Medicine. Undergraduates from other faculties do not differ statistically significantly in the intensity of both motivational factors.

Authors: Nguyen Phong Thanh , Nguyen Thu Anh , Tran Thang Huynh Tat
Published: December 2021

This paper identifies potential barrier factors affecting effectiveness and development (ED) of ITS projects as well as criteria for measuring ED of ITS projects in Ho Chi Minh City, Vietnam. The study discovers the barrier constructs, and analyzes data using the Partial Least Squares Structural Equation Modeling method (PLS-SEM). The results provides a general and comprehensive overview of the main issues of ITS, and identifies 28 barrier factors with five main constructs affecting ED of ITS projects, namely the lack of undivided attention from the government (AG), financial constraints for ITS (FC), inadequate transport infrastructure (ITI), the over-development of urbanization (ODU), and the readiness and integration for ITS (RI). This paper fill the knowledge gap by discovering the causal relationships between barrier constructs and ED of ITS projects in Vietnam. Also it proposes several solutions for these issues, which are also a useful measurement tool for government agencies, planners, and traffic system designers to help them self-assess and make action plans now or in the near future.

Design and psychometric analysis of a suicide risk scale for Argentinean adolescents and young people
Abstract: Suicidal behavior in adolescents and youth has become a public health issue which requires improving the available scales in order to enable the early detection of risk cases. Therefore, for this purpose, this study presents the design and psychometric analysis of the Argentinean Scale of Suicidality for Adolescents (EASA-I by its Spanish acronym) Screening. It measures a specific dimension of suicidal ideation and five risk factors: low self-esteem, negative perspective of the future, low emotion regulation, difficulties in problem-solving and lack of social support. This study was aimed at analyzing content construct and face validity, as well as convergent and discriminant validity evidence with external measures. Internal consistency of the scores was also examined. The sample was composed of 291 adolescents and young adults. Results suggest that the EASA-I constitutes a short and simple scale with adequate psychometric properties suitable to be used in different areas of application and research.
Keywords: adolescents; youth; suicide risk; multidimensional assessment; screening.
Resumen: Los comportamientos suicidas en la adolescencia y la juventud constituyen un problema de salud pública que exige mejorar las herramientas de evaluación disponibles, de cara a detectar precozmente casos en riesgo. Se presenta el diseño y análisis psicométrico de la Escala Argentina de Suicidalidad para Adolescentes EASA-I Screening. Su objetivo reside en la medición de una dimensión específica, i.e., la ideación suicida, más cinco factores de riesgo: baja autoestima, perspectiva negativa del futuro, baja regulación emocional, dificultades para la resolución de problemas y falta de apoyo social. Basándonos en una muestra de 291 adolescentes y jóvenes, se analizaron evidencias de validez de contenido, aparente y de constructo, así como de validez convergente y discriminante con medidas externas. Se examinó, además, la consistencia interna de las puntuaciones obtenidas. Los resultados indican que la EASA-I posee adecuadas propiedades técnicas para su uso en población local en diferentes ámbitos de aplicación e investigación.

How do spouses’ levels of ambivalent sexism predict allocations of household chores? Probing why women still perform most of the work in the U.S.
Authors: Gerst Katherine , Reifman Alan , Niehuis Sylvia , Weiser Dana
Published: December 2021

This study’s main objective was to examine whether, in a U.S. sample, ambivalent sexism would show stronger associations with heterosexual husbands and wives’ housework division (hours and proportion) than have previous gender-ideology measures. Unlike earlier conceptions of sexism emphasizing hostile and negative stereotypical views toward women, ambivalent sexism combines the two dimensions of hostile sexism and benevolent sexism (seemingly positive views and behaviors toward women that nevertheless convey underlying paternalistic and patronizing motivations). We hypothesized that male and female respondents high in both hostile and benevolent sexism would report the typical pattern of wives’ housework exceeding their husbands’, whereas those lower in hostile or benevolent sexism would report less housework being performed by wives. Married individuals (N = 249) were recruited via advertisements on Amazon.com’s Mechanical Turk (MTurk) platform and announcements at a university to complete an online survey. Several variables were measured, including own and spouse’s housework hours, hostile and benevolent sexism, and demographic control variables previously associated with housework allocation. An interaction emerged for women, in which those high in benevolent, but low in hostile, sexism reported performing the highest proportion of housework, whereas those low in both forms of sexism performed the lowest proportion. These results provided full or partial support for different aspects of our hypotheses. Men reported greater housework (hours and proportion) the more hours their wife worked outside the house. Discussion examines implications for ambivalent sexism theory, housework sharing, and conceptions of sexism.

EL PATRIMONIO EN LA IMAGEN TURÍSTICA INDUCIDA DE ANDALUCÍA
Authors: Albarrán Periáñez José David , De la Calle Vaquero Manuel
Published: December 2021

El turismo es un sector eminentemente visual, lo que favorece que los destinos trabajen en la generación de representaciones seductoras con las que atraer a los potenciales visitantes. En este trabajo se analiza el modo en que el patrimonio ha sido incorporado a la construcción de la imagen inducida andaluza en las últimas décadas, desarrollándose un análisis semiótico de las representaciones proyectadas en el material promocional. A través del mismo se constata la idea de que dicha imagen es herencia de la identidad universal de la región construida durante el Romanticismo, en la que imperan los elementos propios de su pasado árabe, determinándose que territorios que cuentan con una imagen universal consolidada, en la que el patrimonio ejerce un papel fundamental, se valen de ésta para la formación de su imagen inducida por su fácil reconocimiento internacional.

Tourism is an eminently visual sector, which encourages destinations to work on generating seductive representations to attract potential visitors. This paper analyses how heritage has been incorporated into the construction of the Andalusian induced image in recent decades, developing a semiotic analysis of the representations projected in the promotional material. Through this, it emerges that this image is the inheritance of the universal identity of the region built during Romanticism, in which the elements of its Arab past prevail. Finally, the study provides that territories that have a consolidated universal image, in which heritage plays a fundamental role, they use it to form their induced image due to its easy international recognition.
Livros didáticos em espaços sociocomunitários
Authors: Gracia Tânia Maria Braga , Barbosa Wagner Luis
Published: December 2021

O estímulo a práticas de leitura deve ser assumido como um dever e um direito, pois é fator de desenvolvimento social especialmente em países com acentuada desigualdade social e acesso restrito de grande parte da população a níveis mais elevados de escolarização. Os livros didáticos, no Brasil, são distribuídos gratuitamente para uso em escolas públicas, em um Programa Nacional criado em 1985 para dar suporte ao ensino. O programa entrega às escolas livros avaliados e aprovados com base em critérios estabelecidos em editais públicos. Os livros são utilizados pelos alunos e alunas e permanecem na escola ao final de cada ano, para serem reutilizados nos anos seguintes, durante ciclos de 3 a 4 anos. Para onde vão os livros quando o ciclo de uso termina? A pesquisa investigou o que acontece com os livros após o seu período legal de uso, para saber se eles continuam circulando, como e onde circulam, quem os utiliza e com quais finalidades. Os procedimentos metodológicos incluíram análise da legislação sobre o descarte de livros, entrevistas em escolas para conhecer processos de reaproveitamento e descarte dos livros e um levantamento exploratório de experiências de reutilização de livros após seu ciclo de uso nas escolas. Os resultados indicaram caminhos que os livros percorrem fora dos muros das escolas, em especial por ações de sujeitos que atuam em cooperativas de catadores de materiais recicláveis que destinam os livros descartados para projetos sociais e para salas de leitura em espaços comunitários, nas regiões periféricas das cidades. As conclusões destacam o valor de experiências individuais e institucionais de reaproveitamento dos livros, apontando sua relevância em comunidades vulneráveis que, assim, dão novos significados e funções aos livros didáticos, evidenciando o valor dessas ações para o desenvolvimento social de tais comunidades.

Published: December 2021

El presente artículo pretende analizar la funcionalidad didáctica de cuatro materiales educativos dirigidos al alumnado de Educación Secundaria Obligatoria y Postobligatoria. El contenido del material, con estructura de unidad didáctica, abarca diferentes aspectos de las ciencias sociales y ha sido diseñado por un equipo mixto de investigadores y docentes, con la finalidad de promover formación ciudadana en los y las discentes. Nuestro análisis se centra en dos aspectos, ya que pretende evaluar la empleabilidad de este material en las aulas, con relación a la promoción de aprendizaje interactivo, e investiga la posición ocupada por el docente con respecto a su alumnado. Estos dos aspectos se consideran factores significativos para una didáctica orientada a la promoción de experiencias de aula en línea con la educación ciudadana. El contexto sociodemográfico se sitúa en el ámbito educativo catalán con una muestra intencional criterial. El tratamiento de los datos recogidos parte de la observación directa no participante en las aulas, y de un análisis léxico-métrico utilizando el programa Iramuteq. Los resultados se tratan a partir de las reflexiones narrativas recogidas durante la observación de la puesta en escena de dicho material, considerando como dimensiones de análisis: el clima de aula, el desempeño de los materiales con relación al desarrollo competencial social del alumnado, y la metodología docente. El estudio concluye sobre la importancia de una preparación adecuada del profesorado, en relación al uso del material didáctico, para generar situaciones de aprendizaje activo, y la necesidad de un planteamiento pedagógico de dicho material que predisponga actividades cuya intención es la de promover estas mismas situaciones, desde enfoques didácticos que permitan tratar la competencia desde contenidos directamente relacionados con ella

Published: December 2021

La presencialidad en las distintas esferas de las relaciones sociales y profesionales de las TIC, ha dado paso a la necesidad de comunicación digital a través de las redes. En este sentido, cobra plena actualidad abordar la problemática relacionada con la brecha digital en poblaciones vulnerables. Esta carencia se pone de manifiesto no solo en la disposición de los recursos tecnológicos, sino también en las competencias asociadas a su uso y utilidad. Este estudio describe esta brecha en un grupo social especialmente vulnerable. Se expone la construcción y los datos de validación del instrumento de medida Valora 1001 diseñado por el grupo de expertos del Observatorio para la Inclusión Social de la Ciudad de León. Con la información recogida en una muestra de 1.125 personas en situación de vulnerabilidad social, los resultados pusieron de manifiesto la existencia de una importante brecha digital, tanto de acceso (disponibilidad de recursos tecnológicos y posibilidad de acceso a internet) como de uso (utilización para la búsqueda de empleo y trámites administrativos), comparados con los valores de referencia a nivel autonómico y estatal, situando a este grupo poblacional en situación de fractura social. La solución a esta profunda desigualdad conlleva la implantación de políticas activas que fomenten, no solo la adquisición de recursos e infraestructura, sino que motiven y formen a los ciudadanos en su uso y apropiación. Sería necesario que las administraciones competentes tomaran medidas específicas para atender a esta población, mediante la realización de talleres y cursos de formación en el manejo de estas herramientas tecnológicas. Se describen algunas de las que ha adoptado el Ayuntamiento de León basándose en los resultados alcanzados en este estudio.

Marine sediments harbor an outstanding level of microbial diversity supporting diverse metabolic activities. Sediments in the Gulf of Mexico (GoM) are subjected to anthropic stressors including oil pollution with potential effects on microbial community structure and function that impact biogeochemical cycling. We used metagenomic analyses to provide significant insight into the potential metabolic capacity of the microbial community in Southern GoM deep sediments. We identified genes for hydrocarbon, nitrogen and sulfur metabolism mostly affiliated with Alpha and Betaproteobacteria, Acidobacteria, Chloroflexi and Firmicutes, in relation to the use of alternative carbon and energy sources to thrive under limiting growth conditions, and metabolic strategies to cope with environmental stressors. In addition, results show amino acids metabolism could be associated with sulfur metabolism carried out by Acidobacteria, Chloroflexi and Firmicutes, and may play a crucial role as a central carbon source to favor bacterial growth. We identified the tricarboxylic acid cycle (TCA) and aspartate, glutamate, glyoxylate and leucine degradation pathways, as part of the core carbon metabolism across samples. Further, microbial communities from the continental slope and abyssal plain show differential metabolic capacities to cope with environmental stressors such as oxidative stress and carbon limiting growth conditions, respectively. This research combined taxonomic and functional information of the microbial community from Southern GoM sediments to provide fundamental knowledge that links the prokaryotic structure to its potential function and which can be used as a baseline for future studies to model microbial community responses to environmental perturbations, as well as to develop more accurate mitigation and conservation strategies.
Aerodontalgia among Airline Pilots of India: A Cross-sectional Survey
Authors: Gujral Sabreen , Chopra Shruti , Sood Shveta , Sharma Naresh , Singh Akshara
Published: December 2021

Introduction: Barometric pressure-induced dental pain is a clinical entity elicited by atmospheric changes in pressure. Barodontalgia (also known as aerodontalgia) among pilots is of marked interest as it can be a potential flight safety hazard and compromise the personnel’s operational capability and performance. Due to its overlapping signs and symptoms, it may also remain unnoticed and represent itself during a pressure change which may be during ascend or descend of flight. Aim: To assess presence of barodontalgia and awareness of the phenomenon among commercial pilots based in India. Materials and Methods: This cross-sectional study was conducted from June to August 2020 using self-reported questionnaire submitted via Google forms (Alphabet, Mountain view, CA, USA) among 410 pilots based in India. It consisted of questions inquiring about the occurrence, localisation, intensity and recurrence of in- flight dental pain. Inferential statistics were performed using Chi- square test, One way analysis of variance (ANOVA) and Independent t-test. The level of statistical significance was set at 0.05. Results: A total of 370 pilots responded to the questionnaire with a response rate of 90.24%. The incidence was reported among 10.54% (n=39) pilots although 42.7% (n=158) lacked awareness regarding the same. Only a single case of recurrence of pain was reported while none reported any risk to flight safety or accident, secondary to barodontalgia. Conclusion: The incidence level of barodontalgia among commercial pilots in India is low. However, the lack of awareness is still an unsettling risk and was not found to be of significant difference when compared on the basis of gender and work experience.

В работе исследованы распределения As в p-n-структурах, формируемых в сильнолегированном кремнии КДБ 0,001 (концентрация 1,3 10 см) диффузией As в эвакуированной ампуле. Использовались методы дифференциальной проводимости и нейтронно-активационный. Выявлено существенное различие распределений, что объясняется наличием части As в диффузионном слое в электрически неактивной форме в виде нейтральных кластеров вакансионного типа VAs. Параллельно исследованиям профилей As исследованы профили распределения в кремнии КДБ 0,001 фосфора, полученные диффузией в газовой фазе с источником в виде треххлористого фосфорa PCl в аналогичном по температуре и времени режиме диффузии. Полученные активационные профили распределения As и Р служат наглядным подтверждением преимуществ выбора донорной примеси As относительно других легирующих примесей для формирования в сильнолегированном кремнии низковольтных р-n-структур с туннельным и смешанным механизмами пробоя (напряжение пробоя U < 6 В), на основе которых изготавливаются низковольтные стабилитроны и ограничители напряжения. Критерии сравнения: соотношение поверхностных концентраций – Ns мышьяка 1 10 см, Ns фосфора 1,6 10 см, глубины залегания p-n-переходов – xj мышьяка 2 мкм, xj фосфора 1 мкм соответственно.

Aims: Pterygota macrocarpa, a common species in the forests of Côte d'Ivoire, is threatened with extinction due to overexploitation. Protective measures for P. macrocarpa could consist in the integration of arbuscular mycorrhizae in the reforestation of this species. The objective of this study was to evaluate the impact of arbuscular mycorrhizae inoculation on the resistance and development of P. macrocarpa plants.

Study Design: The design is completely randomized and includes one (1) plant species (Pterygota macrocarpa), three (3) treatments (local inoculum 1, commercial inoculum 2 and non-inoculated control) and 20 seedlings per treatment.

Place and Duration of Study: The experimental study was set up at the border of the experimental forest of the Northern site of INP-HB (National Polytechnic Institute Houphouët-Boigny, Yamoussoukro, Côte d’Ivoire) from February to May 2018.

Methodology: Thus, from seedlings collected in the arboriculture of the INP-HB of Yamoussokro, the effects of mycorrhization through treatments on the mineral nutrition and on the growth parameters of P. macrocarpa were evaluated during 120 days of culture in nursery.

Results: The mycorrhised plants survived 100% while the control plants had 90% survival rate. The mycorrhizal intensity of the roots was 19.21% for inoculum 1 and 10.40% for inoculum 2. The plants treated with inoculum 1 had the highest mineral content, especially phosphorus (0.3 ppm) and nitrogen (2.6%). The vegetative growth of inoculum 1 treated plants was more accelerated than that of the other two treatments. Local inoculum 1 was more effective than commercial inoculum 2.

Conclusion: The integration of local mycorrhizal inocula in the reforestation of P. macrocarpa seedlings could be a sustainable solution for the restoration of degraded forests.

Background: Atorvastatin is a recent HMG-COA reductase inhibitor used to treat primary hypercholesterolemia, homozygous familial hypercholesterolemia, and mixed dyslipidemias. It is also taken to prevent heart disease, including strokes and heart attacks. In addition, Atorvastatin is used to lower bad cholesterol low-density lipoproteins (LDL) levels, increase good cholesterol high-density lipoprotein (HDL) levels, and lower triglycerides. It works by reducing the amount of cholesterol produced in the body, hence reducing the amount of cholesterol that may build up on the walls of arteries. Atorvastatin is long-acting, has few adverse effects, and is low in price. Nevertheless, it interacts with a wide variety of medications. These interactions may be lead to adverse drug reactions.

Objective: The study aims to identify and asset atorvastatin interactions with other medicines at King Abdulaziz Hospital. Also, to prevent atorvastatin interactions in the future.

Methods: The retrospective study investigated 280 electronic prescriptions inside the inpatient clinic at King Abdulaziz Hospital in Saudi Arabia between January and April 2021 to identify and asset interactions among atorvastatin and different medications.

Results: Most atorvastatin interactions are category C (44.64%) and category B (41.43%). Atorvastatin had the most common interactions with esomeprazole (16.07%), clopidogrel (14.64%), and sitagliptin (12.14%). Atorvastatin had clinical interactions with medications metabolized by the cytochrome P450 3A4 )CYP3A4(. Use of atorvastatin with cyclosporine or clarithromycin increased the risk for atorvastatin toxicities such as myopathy and rhabdomyolysis. In addition, Atorvastatin decreases clopidogrel's antiplatelet effect and increases the risk of skeletal muscle toxicity of daptomycin.

Conclusion: The majority of atorvastatin interactions may be avoided by adhering to best practices in clinical care and clinical pharmacology, such as avoiding complicated treatment regimens, utilizing a single pharmacy for all prescriptions, and recognizing patient risk factors. Health care professionals should use drug-drug interaction checkers such as Medscape and Micromedex, as well as a book such as the Handbook of Drug Interactions.

Osteosarcoma (OS) is the most common primary malignancy of bone. Epigenetic regulation plays a pivotal role in cancer development in various aspects, including immune response. In this study, we studied the potential association of alterations in the DNA methylation and transcription of immune‐related genes with changes in the tumor microenvironment (TME) and tumor prognosis of OS. We obtained multi‐omics data for OS patients from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) and Gene Expression Omnibus (GEO) databases. By referring to curated immune signatures and using a consensus clustering method, we categorized patients based on immune‐related DNA methylation patterns (IMPs), and evaluated prognosis and TME characteristics of the resulting patient subgroups. Subsequently, we used a machine‐learning approach to construct an IMP‐associated prognostic risk model incorporating the expression of a six‐gene signature (MYC, COL13A1, UHRF2, MT1A, ACTB, and GBP1), which was then validated in an independent patient cohort. Furthermore, we evaluated TME patterns, transcriptional variation in biological pathways, somatic copy number alteration, anticancer drug sensitivity, and potential responsiveness to immune checkpoint inhibitor therapy with regard to our IMP‐associated signature scoring model. By integrative IMP and transcriptomic analysis, we uncovered distinct prognosis and TME patterns in OS. Finally, we constructed a classifying model, which may aid in prognosis prediction and provide a potential rationale for targeted‐ and immune checkpoint inhibitor therapy in OS.
Comparative transcriptomics of the Djungarian hamster hypothalamus during short photoperiod acclimation and spontaneous torpor

The energy‐saving strategy of Djungarian hamsters (Phodopus sungorus, Cricetidae) to overcome harsh environmental conditions comprises of behavioral, morphological, and physiological adjustments, including spontaneous daily torpor, a metabolic downstate. These acclimatizations are triggered by short photoperiod and orchestrated by the hypothalamus. Key mechanisms of long‐term photoperiodic acclimatizations have partly been described, but specific mechanisms that acutely control torpor remain incomplete. Here, we performed comparative transcriptome analysis on hypothalamus of normometabolic hamsters in their summer‐ and winter‐like state to enable us to identify changes in gene expression during photoperiodic acclimations. Comparing nontorpid and torpid hamsters may also be able to pin down mechanisms relevant for torpor control. A de novo assembled transcriptome of the hypothalamus was generated from hamsters acclimated to long photoperiod or to short photoperiod. The hamsters were sampled either during long photoperiod normothermia, short photoperiod normothermia, or short photoperiod‐induced spontaneous torpor with a body temperature of 24.6 ± 1.0 °C, or. The mRNA‐seq analysis revealed that 32 and 759 genes were differentially expressed during photoperiod or torpor, respectively. Biological processes were not enriched during photoperiodic acclimatization but were during torpor, where transcriptional and metabolic processes were reinforced. Most extremely regulated genes (those genes with |log2(FC)| > 2.0 and padj < 0.05 of a pairwise group comparison) underpinned the role of known key players in photoperiodic comparison, but these genes exhibit adaptive and protective adjustments during torpor. Targeted analyses of genes from potentially involved hypothalamic systems identified gene regulation of previously described torpor‐relevant systems and a potential involvement of glucose transport.
