Abstract: 

Introduction and purpose: This review aims to analyze causes, symptoms and diagnosis of overdosing vitamin D resulting in vitamin D toxicity (VDT). 

Material and method: This paper was based on medical articles collected in Pubmed from 2008 to 2021 year. The research has been done by looking through keywords such as “vitamin D” “toxicity”. 

Results: The review of studies showed that manifestation of VDT is mainly associated with hypercalcemia and its course can range from asymptomatic to life-threatening, including death. We also draw attention to inappropriate use and widespread of vitamin D products. 

Conclusion: There is a high demand for medical health workers to advise patients on possible effects of inappropriate use of vitamin D products and its toxicity. Medical practitioners should be attentive to quickly identify VDT.
Cuerpos migrantes: resistencias culturales y desigualdades entrelazadas

Published: August 2022

Este ensayo surge como parte de un proceso de exploración conceptual y empírica en torno a la disputa y transformación del espacio público, tanto en su expresión material como simbólica, a través de prácticas culturales. En particular, me he enfocado en aquellas expresiones que tienen un carácter performático, en consideración de la capacidad que tienen los cuerpos de irrumpir en el cotidiano, producir el espacio y generar presencias colectivas, al mismo tiempo que cons­tituye procesos de enunciación desde las diferencias. Esto resulta especialmente significativo para quienes tienen un acceso restringido a la constitución de lo público, dadas ciertas relaciones de poder que definen quién y qué cuenta para una comunidad. A partir de esta observación se analiza el caso de Mery Cortez Ortiz, madre de un joven ecuatoriano asesinado por el Ejército en el marco del llamado “Estallido social chileno”, desde una revisión bibliográfica y de prensa.

To describe survival according to prognostic factors of women with breast cancer in French overseas territory (Martinique) during 2008–2017. We performed a Cox model for prognostic factors for OS in breast cancer patients. The cut-off date for the analysis was 13/10/2018. The main factors were demographic data, stage, hormone receptors (HR) status and HER2 status. Curves were compared with the log rank test to select candidate variables for the multivariate analysis. We included 1,708 patients; median age at diagnosis was 57 years. Triple negative breast cancer (TNBC) accounted for 20.9% (n = 332). Among the patients, 72.3% (n = 1015) had localised or local spread cancer. One-year OS was 95.2% and was 80.1% at 5 years. In TNBC, 1-year-survival was 90.4%, which fell to 70.1% at 5 years. Patients with metastatic disease at diagnosis had 1-year-survival of 74.5%, and 20.1% at 5 years. Multivariate analysis by Cox regression identified 4 factors significantly associated with an increased risk of death: metastatic disease at diagnosis (hazard ratio (HR) = 15, p<0.0001), TNBC (HR 2.84, p<0.0001), HR+/HER2- status (HR 2.05, p<0.0084) and age >75 years (HR 3.8, p<0.0001). This is the first study performed on breast cancer survival in Martinique. Our findings show that breast cancer has overall good prognosis in patients and also how prognosis factors are distributed in the population.
Fragmentation of hunting bullets observed with synchrotron radiation: Lighting up the source of a lesser-known lead exposure pathway
Authors: Leontowich Adam F. G. , Panahifar Arash , Ostrowski Ryan
Published: August 2022

Bullet fragments have been previously observed in the remains and edible portions of big game animals that were harvested using rifles. The fragmentation issue has attracted attention because traditional hunting bullets are more than 70% lead, which is toxic to humans and scavengers in the ecosystem. We prepared gunshot wounds in ballistic gelatin blocks, and then applied synchrotron X-ray imaging technology to the bullet fragmentation process for the first time. The K edge subtraction (KES) imaging method allowed a clear separation of lead in an image from false positives, including the other major bullet component, copper, and non-lead objects such as bone fragments. The superior brightness of synchrotron radiation was also harnessed to resolve thousands of embedded sub-10 μm fragments, a size range not previously observed using commonly applied X-ray imaging modalities. The results challenge the current understanding of the maximum extent that fragments may be distributed, and the effectiveness of imaging methods used to screen wild game donations at food banks for lead bullet fragments.
Dietary self-care and associated factors among diabetic patients in Jimma University Medical Centre, South West Ethiopia; A path analysis
Authors: Jemal Musa , Argaw Alemayehu , Taye Abonesh , Sintayehu Tsion , Kedir Shemsu
Published: August 2022

Background

Diabetes Mellitus (DM), a chronic metabolic disorder that caused about 4.2 million deaths and at least 760 billion dollars’ expenditure in 2019, has been targeted for action by leaders of WHO member countries. In Ethiopia deaths, due to DM reached 34,262 in 2013. Studies show effective lifestyle interventions; particularly medical nutrition therapy reduces HbA1c by 0.5 to 2%. However, practicing recommended diet is reported to be difficult. Not only Knowledge and practice but also perception studies are therefore necessary to design future health programs.

Objective

To assess diabetic self-care, dietary practice and associated factors among diabetes patients.

Method

Institution-basedbased cross-sectional study design was employed from february15-May15, 2020 in Jimma university medical Centre (JUMC). Systematic sampling of every other patient (K = 2.7) was employed to interview 371 participants. A previously validated tool was used to collect data through a face-to-face interview. A path analysis was used to fit the structural model and tests the hypothesized Health Belief Model (HBM) relationships.

Result

Response rate was 95.4% (354). Around 52% of the participants were male and 76.8% follow diabetic education at least some times. 42.4% and 48% of respondents have good dietary and general self-care practices respectively. With unstandardized coefficient (standard error) self-efficacy0.10 (0.01) being the strongest cues to action0.10 (0.02), perceived threat0.02 (0.01), and perceived barrier-0.08(0.01) constructs of HBM have a significant effect on dietary practice. Knowledge, social support and diabetes distress exert a significant indirect effect on dietary practice through health belief constructs with unstandardized path coefficient (standard error) of 0.22(0.03), 0.02(0.01), and -0.03(0.004) respectively.

Conclusion

In this study, the proportion of good practice is found to be lower for both dietary as well as general self-care. HBM can best fit to explain variability in dietary self-care practice; therefore, future interventions should be designed to address the vast perception and psychosocial factors influencing dietary self-care practices.
Corrosion behaviour OF HVOF deposited Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coatings on mild steel
Authors: Ali Sheikh Idrees , Ahmad Sheikh Nazir
Published: August 2022

In this study, Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coatings were deposited using high-velocity oxy-fuel (HVOF) thermal spray technique on a mild steel substrate. Corrosion tests like neutral salt spray (NSS) following (ASTM B-117) standard and immersion cycle test following ASTM G-31, ASTM G1-03, standards were carried out for Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coated mild steel along with uncoated mild steel acting as a control. Both Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coated mild steel were corrosion resistant as compared to uncoated mild steel. Raman analysis following the immersion cycle test inferred that uncoated mild steel had all forms of rust. While Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coated mild steel developed very little rust. The characterization helped to understand the changes in the surface before and after tests. It was observed that both Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coated mild steel had little corrosion degradation of surface as compared to uncoated mild steel. Suggesting that both coatings performed significantly better compared to uncoated mild steel in corrosive environments. Polarization and EIS tests of both coated and uncoated mild steel in a 3.5% NaCl medium helped to understand the behaviour of coatings over a range of frequencies. Both coated samples had high polarization potential E
corr values and lower polarization current I
corr values as compared to uncoated mild steel. Inferring better performance of coatings in corrosive environments as compared to uncoated mild steel.

Impacts of long noncoding RNA MALAT1 on LPS-induced periodontitis via modulating miR-155/SIRT1 axis
Authors: Hu Wanjun , Lei Xiubing , Luo Jianglong , Gou Xing
Published: August 2022

Objectives

Periodontitis, a dental disease that causes inflammation of gums is triggered by a bacterial infection. Long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (lncRNA MALAT1) has been reported to participate in inflammatory diseases. In the present study, we investigated the effects of lncRNA MALAT1 on periodontal ligament cells (PDLCs) with lipopolysaccharide (LPS) induction.

Methods

MALAT1, microRNA-155 (miR-155), Sirtuin 1 (SIRT1), Bax, and Bcl-2 RNA expressions were detected by using real-time quantitative polymerase chain reaction (RT-qPCR). PDLC viability and apoptosis were assessed by using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium salt (MTT) assay and flow cytometry. Enzyme-linked immunosorbent assay (ELISA) assessed secretions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Luciferase reporter test was applied for confirming the binding of miR-155 with MALAT1 and SIRT1, respectively.

Results

Overexpression of MALAT1 facilitated the LPS-induced periodontitis while MALAT1 suppression restrained LPS-induced injury. Also, miR-155 was expressed in LPS-induced PDLCs. Moreover, MALAT1 negatively regulated miR-155 followed by the up-regulation of SIRT1 which in turn reduced the inflammation in LPS-induced PDLCs.

Conclusions

We concluded that upregulated lncRNA MALAT1 could accelerate periodontitis through the regulation of miR-155/SIRT1. Our findings suggested a novel MALAT1/miR-155/SIRT1 pathway for the treatment of periodontitis.
Metodología para evaluar la vulnerabilidad de sistemas hidrológicos ante los potenciales efectos del cambio climático
Authors: Orozco Medina Ismael , Martínez Bárcenas Adrián
Published: August 2022

Existe una gran incertidumbre sobre el grado de vulnerabilidad de un sistema hidrológico ante los potenciales efectos del cambio climático, principalmente la posible alteración del régimen pluvial, además de las prácticas poco eficientes, la sobreexplotación de acuíferos y el tratamiento inadecuado de aguas. Es por ello que esta investigación se ha enfocado a determinar la vulnerabilidad actual y futura de los sistemas hidrológicos a través de una metodología que acopla un modelo hidrológico distribuido, un modelo de circulación general, un modelo de crecimiento poblacional, redes neuronales artificiales (ANN, por sus siglas en inglés) y una serie de indicadores que describen de forma integral el sistema. Esta metodología ha permitido proyectar la vulnerabilidad del sistema al futuro cercano (año 2035) para los escenarios RCP4.5, RCP6.0 y RCP8.5. Los resultados obtenidos muestran que el sistema ya es vulnerable y que el escenario RCP4.5 presenta las mayores vulnerabilidades con una alta variabilidad espacial y temporal.

Authors: Rodríguez Egas Nathalie Alejandra , Fernández Muñoz Cristóbal
Published: August 2022

Este artículo estudia las técnicas de comunicación persuasiva y neuromarketing aplicadas a publicidad alimentaria en redes sociales. En concreto, se efectúa un análisis de campañas relativas al consumo de azúcar. Este estudio tiene como objetivo explicar algunos factores predominantes en la viralización de bulos nutricionales a través del análisis de los casos de: “149 calorías de felicidad” de Coca-Cola y de la campaña crema de cacao del influencer Carlos Ríos del movimiento Real Fooding. La metodología utilizada responde a técnicas como el análisis Backwards Mapping, según la teoría del cambio, para evaluar el impacto social. La fundamentación teórica utiliza como referencia los sesgos cognitivos del neuromarketing en concordancia con varios autores especializados de los cuales se amplía en la metodología. La observación del alcance de las campañas analizadas en Redes sociales traza la relación causal con respecto al efecto en el público e impacto generado en el periodo establecido. La viralización e impacto de estas campañas se ha medido a partir de indicadores cuantitativos y cualitativos. En base a los resultados obtenidos, se constata cómo la controversia acerca de la fiabilidad de la información ha afectado la percepción de la campaña, el grado de satisfacción del usuario y la reputación de los promotores de los productos en cuestión.

The emergence of SARS‐CoV‐2 variants has exacerbated the COVID‐19 global health crisis. Thus far, all variants carry mutations in the spike glycoprotein, which is a critical determinant of viral transmission being responsible for attachment, receptor engagement and membrane fusion, and an important target of immunity. Variants frequently bear truncations of flexible loops in the N‐terminal domain (NTD) of spike; the functional importance of these modifications has remained poorly characterised. We demonstrate that NTD deletions are important for efficient entry by the Alpha and Omicron variants and that this correlates with spike stability. Phylogenetic analysis reveals extensive NTD loop length polymorphisms across the sarbecoviruses, setting an evolutionary precedent for loop remodelling. Guided by these analyses, we demonstrate that variations in NTD loop length, alone, are sufficient to modulate virus entry. We propose that variations in NTD loop length act to fine‐tune spike; this may provide a mechanism for SARS‐CoV‐2 to navigate a complex selection landscape encompassing optimisation of essential functionality, immune‐driven antigenic variation and ongoing adaptation to a new host.

IS MEMBRANE USAGE REALY NECESSARY FOR SINUS LIFTING OPERATION IN LATERAL WINDOW TECHNIQUE
Authors: OCAK Hakan , DEMETOĞLU Umut , GÜRSOYTRAK Burcu , ÇOLPAK Halis Ali , YILDIRIM Gülsün
Published: August 2022

Background
Although the placement of a membrane after sinus floor augmentation promotes faster initialization of bone formation, there is evidence that these procedures may be successful and predictable without membrane barriers. The aim of this study was to investigate the presence of defects that might occur due to soft tissue invasion in the antrostomy area in two groups where membrane application was used or not used on the lateral window.

Methods
Comparisons of implant survival in the groups and the amounts of bone generation were also investigated. Forty patients were selected for the study, and they were randomized into two groups in which membrane application was used (study group) or not used (control group). Twelve months following the procedure, images of the region were taken with computerized dental volumetric tomography.

Results
The difference between the groups in terms of bone diameter was evaluated with an independent t test. No defect areas were found radiographically in the lateral window region in the groups. The mean bone diameter of the control group was 13.063 mm (±2.4 mm) and that of the study group was 14.10 mm (±5.8 mm). There was no significant difference between the groups in bone diameter. There were no losses in any of the implants that were placed in either group.

Conclusion
The use of a membrane to close the lateral window did not play any important role in the formation of bone defects.

Published: August 2022

The magnetoresistance of GaPxAs1-x (x = 0…0.45) whiskers with doping concentration of silicon in the range from the deep dielectric side of metal-insulated transition (~1017 сm-3) to its critical concentration (Nc ~ 5´1018 сm-3) at cryogenic temperatures of 4.2¸77 K and magnetic field induction of 0¸14 T was studied. A negative magnetic resistance (NMR) with maximum value of 7 % was found at temperature 4.2 K and magnetic field 4.5 T, which is dependent on magnetic field induction and current direction. The NMR absolute value reduces with increasing temperature was observed in the transverse and longitudinal magnetoresistance. The nature of the revealed NMR effect was discussed in the studied samples. There are four possible reasons of the NMR effect in the GaPxAs1-x whiskers such as the dimensional quantization, the magnetic ordering of electron spins or magnetic ordering due to uncontrolled magnetic dopant introduction and quantum interference of the electron wave function. The GaPxAs1-x whisker application as the temperature sensor was proposed due to the studied results of the temperature dependence of their conductivity.

Authors: Sanchez Gonzalez Juan Franco , Attorresi Horacio Félix , Abal Facundo Juan Pablo
Published: August 2022

El Neuroticismo (N), a pesar de ser un rasgo de personalidad normal, se vincula con el padecimiento de diversas psicopatologias. Se estudió la continuidad entre el N y su variante desadaptativa, la Afectividad Negativa (AN), aplicando un modelo de la Teoría de Respuesta al Ítem (TRI) a dos escalas que miden estos constructos. Participaron 619 personas de población general (64.3 % mujeres), quienes respondieron un protocolo que incluyó 20 ítems de N del International Personality Item Pool (IPIP-NEO) y 23 ítems de AN del Personality Inventory for DSM-5 (PID-5). Inicialmenete se realizó una depuración progresiva de los ítems de N y AN a partir de criterios psicométricos del Modelo de Respuesta Graduada. Luego se calibraron conjuntamente los 22 ítems retenidos aunque se eliminaron 6 ítems por mostrar dependencia local y problemas de ajuste. Se aportaron evidencias de la continuidad postulada entre N y AN. Sin embargo, se encontró un marcado solapamiento en la localización de los ítems procedentes de ambas escalas en el continuo del rasgo que conforman N y AN.

Published: August 2022

Este artículo presenta una propuesta metodológica y epistémica para el desarrollo de proyectos de investigación que, desde las ciencias sociales, las ciencias de la salud, las artes y las humanidades involucran a niños, niñas y jóvenes que viven con enfermedades crónicas, o a sus familias y agentes relacionales como pares, agentes educativos, personal médico y comunidad próxima. Se plantea esta propuesta reconociendo la necesidad de generar investigaciones híbridas que comprendan nuevas formas de aproximación a los sujetos y a su realidad. El documento recoge un análisis que permite comprender la importancia del cuidado de la intimidad y el respeto por los lenguajes artísticos, simbólicos y metafóricos de los niños y las niñas, especialmente en contextos de vulnerabilidad en donde la vida adquiere mayor valor y significado. Finalmente, tomando recursos de las ciencias sociales y las artes, se presenta una metodología simbiótica, denominada hermenéutica sensible y creativa, la cual se fundamenta en la hermenéutica y las artes para permitir que quienes viven en situación de enfermedad encuentren recursos propios y resignifiquen su experiencia de vida.
Teorías cognitivas dinámicas o de tercera generación: análisis documental de artículos originales de investigación cualitativa
Authors: Pérez-Parra Julio Ernesto , Restrepo de Mejía Francia
Published: August 2022

En los últimos años ha crecido el interés por la búsqueda de evidencia científica sobre el nuevo paradigma de la cognición dinámica, pero la gran mayoría de publicaciones se han hecho a partir de diseños cuantitativos, lo que evidencia que es necesario complementar la investigación con diseños cualitativos. El objetivo del presente manuscrito es valorar la cantidad y calidad de la publicación científica basada en diseños de investigación cualitativos, en el área de las teorías dinámicas de la cognición o teorías cognitivas de tercera generación. Estas teorías proponen que la cognición es un fenómeno corporeizado, extendido, situado y enactivo. Se realizó un análisis documental en las principales bases de datos internacionales sobre artículos científicos con diseño cualitativo. Se seleccionaron catorce (14) artículos que cumplieron los criterios de inclusión y respondían al objetivo de la revisión. Se encontró que, aunque la investigación cualitativa en este campo es escasa, comparada con la investigación cuantitativa, se observó un potencial de estos diseños en el estudio de las teorías cognitivas dinámicas en distintos ámbitos, a saber, psicología, salud, funcionamiento y discapacidad, educación, actividad física y deporte, arte, lingüística, filosofía de la mente, entre otros. Los resultados y conclusiones de las investigaciones revisadas aportan sustento teórico de la cognición corporeizada, enactiva, extendida y situada, y soportan el objeto de estudio de las ciencias cognitivas emergentes: “el sistema cerebro-cuerpo-en el mundo”.

Published: August 2022

El propósito de este trabajo es presentar un estado del arte sobre los estudios en el campo académico de la discapacidad en un intento por aportar  elementos teóricos a quienes vienen trabajando la discapacidad como problema social y no como un asunto de tipo médico y rehabilitador. Se realizó una revisión documental de artículos de investigación, capítulos de libros y libros en diversas bases de datos  donde se analizaron 55 fuentes documentales utilizando como técnica el análisis documental a partir del instrumento de la regilla documental. Entre los resultados se destaca que los problemas sobre los que ha girado el estudio de la discapacidad han sido en educación inclusiva, desarrollo humano, justicia social, estudios decoloniales y críticos de la discapacidad, y alrededor de la identidad y el reconocimiento. Se concluye que aún prevalece una mirada a la discapacidad y las personas con discapacidad desde la deficiencia, la superación, la rehabilitación y la limitación, y aunque existen estudios que interpelan a los sujetos con discapacidad, en estos prevalecen los abordajes alrededor de los obstáculos o elementos facilitadores para la inclusión.

Authors: Romero León Manuel Alejandro , Martínez Aguilera Cynthia
Published: August 2022

El objetivo de la investigación es elaborar una metodología para desarrollar la psicomotricidad de niños con disartria pseudobulbar que revele las peculiaridades fundamentales del proceso. La problemática fundamental se dirige a las carencias detectadas en el proceso didáctico de los estudiantes con este trastorno que restringen su desarrollo psicomotriz y su inclusión social. Los referentes principales de la temática son Bécquer (2002), López (2012), Figueredo (2014) y Huepp (2018). Ellos han ofrecido tratados cognitivos en las dimensiones motriz, cognitiva y afectiva de los alumnos; no obstante, sus contribuciones no se destinan a personas con disartria pseudobulbar. Para la investigación fueron empleados métodos científicos como el análisis-síntesis, sistémico estructural funcional, así como técnicas entre las que se encuentran pruebas motoras y el estudio de caso. La propuesta contribuye, desde el desarrollo de operaciones psicomotrices, a beneficiar la eficacia motora y la inclusión social de los escolares con este trastorno y les permite apropiarse de una movilidad independiente, segura y con calidad, desde la superación de barreras sociales impuestas.

Del aula al consultorio: propuesta inmersiva para fortalecer competencias laborales en contadores públicos
Authors: Romero Cristian , Escarraga Catalina
Published: August 2022

Desde una investigación desarrollada en Bogotá (Colombia), se evidenció la importancia de fortalecer, durante la etapa lectiva, las competencias laborales del hacer en los contadores públicos. Allí surgió el objetivo de proponer un consultorio contable comunitario como estrategia pedagógica para atender esta necesidad y apoyar la inserción laboral de los estudiantes de contaduría. Mediante el método cualitativo, se abordó el fenómeno desde sus protagonistas, usando la hermenéutica contextual al triangular entrevistas, encuestas semiestructuradas y relatos emergentes. Se concluyó que las competencias del saber y del ser son fortalecidas mientras el estudiante desarrolla competencias del hacer en escenarios reales, en los cuales la inmersión resulta pertinente. La investigación, acudiendo a la autogestión universitaria, planteó una didáctica en contextos comunitarios que facilite la práctica en espacios reales y fortalezca el perfil laboral usando el voluntariado disciplinar; así, los contadores en formación se acercan a la práctica durante la etapa académica mediante la consultoría.

Artigo sobre o ensaio que é romance
Authors: Veloso Jeymeson de Paula
Published: August 2022

O presente artigo objetiva realizar uma leitura do romance Ensaio sobre a cegueira (1995), de José Saramago, abordando o processo de mescla genológica que permeia toda a obra e que compõe a lista das características atribuídas aos romances pós-modernos. A mescla genológica questiona a função fixa dos gêneros literários, revisando o conforto do pacto ficcional estabelecido entre o leitor e a obra de ficção. Apesar de não ser um artifício novo na literatura, no Ensaio sobre a Cegueira temos um processo deliberado de mistura de gêneros que remonta às primeiras obras de José Saramago, a exemplo do romance Manual de Pintura e Caligrafia (1977). Para realizar a pesquisa, são utilizados os estudos teóricos de Lyotard (2011) para discutir a pós-modernidade como um novo momento sociopolítico cultural. Posteriormente, estreitando o debate, são utilizados os trabalhos de Hutcheon (1991) e Arnaut (2002), apresentados em diálogo com Luiz Costa Lima (2002), Aguiar e Silva (1993), e Angélica Soares (2007) para a elaboração do conceito de gênero textual, especificamente, o gênero literário e como eles se fundem na obra saramaguiana. Verifica-se que essas características, embora abordadas separadamente, concorrem para a fragmentação da narrativa e para sua leitura como uma obra pós-modernista.

Az emlő bőrén kialakuló pyoderma gangrenosum egy igen ritka, hirtelen kezdődő ulceratív betegség. Hátterében leggyakrabban szisztémás kórok áll, a gyulladásos bőrelváltozás kialakulását leggyakrabban műtét vagy trauma indítja be. A betegség korai diagnózisa és megfelelő kezelése igazi kihívás. Egy diabetes mellitusban szenvedő nőbeteg emlőjének bőrén minor sérülést követően kialakult pyoderma gangrenosum esetét mutatjuk be. Kezdetben bakteriális fertőzésként kezeltük, később a pontos diagnózis birtokában terápiánkat szisztémás szteroidokra váltottuk, végül a beteg kérésére emlőjét abláltuk.

Scientific efforts have been made for a better understanding of the pathogenesis of hepatocellular carcinoma (HCC). We investigated the possible role of miR-192/nuclear factor-κB (NF-κB)/transforming growth factor-β (TGF-β)/E-cadherin in hepatic tumorigenesis. We expected a modulatory impact of thymoquinone. Thirty adult male rats were assigned into 3 groups (n = 10); (1) Control group. Group (2): Experimental HCC induced by intraperitoneal injection of diethylnitrosamine (DENA) followed by carbon tetrachloride (CCl4). Group (3): Thymoquinone 20 mg kg−1/oral supplementation starting from the model induction to the end of the 8th week. The HCC (DENA-CCL4) model was confirmed by elevated serum levels of alpha-fetoprotein and transaminases (ALT, AST) and by histopathological examination which denoted marked cellular atypia and features of neoplasia. Suppressed hepatic miR-192 and E-cadherin expression were detected in the HCC (DENA-CCL4) group accompanied by elevated tumor necrosis factor (TNF-α), interleukin (IL6)/NF-κB & TGF-β1. Thymoquinone treatment protected the rat livers from hepatic tumorigenesis. Thymoquinone diminished (P < 0.001) alpha-fetoprotein and improved ALT, AST. It preserved hepatic miR-192 and normal E-cadherin expression. Thymoquinone-treated rats showed abrogated TNF-α, IL6/NF-κB/TGF-β. Thymoquinone increased cell apoptosis markers Bax/Bcl2 and diminished cellular atypia. Pearson's correlations revealed positive association between miR-192 expression and E-cadherin and Bax/Bcl2 as well, and it was negatively correlated to alpha-fetoprotein, NF-κB and TGF-β and the cellular atypia score. In conclusion, thymoquinone protected the liver tissues through preserving miR-192 and E-cadherin and aborting NF-κB & TGF-β signaling. The current results highlight a new role for thymoquinone in preventing hepatic tumorigenesis.
Conditions near a crack tip: Advanced experiments for dislocation analysis and local strain measurement
Authors: Gammer Christoph , An Dayong
Published: August 2022

The local stress state and microstructure near the crack-tip singularity control the fracture process. In ductile materials multiple toughening mechanisms are at play that dynamically influence stress and microstructure at the crack tip. In metals, crack-tip shielding is typically associated with the emission of dislocations. Therefore, to understand crack propagation on the most fundamental level,in situtechniques are required that are capable to combine imaging and stress mapping at high resolution. Recent experimental advances in x-ray diffraction, scanning electron microscopy, and transmission electron microscopy enable quantifying deformation stress fields from the bulk level down to the individual dislocation. Furthermore, through modern detector technology the temporal resolution has sufficiently improved to enable stress mapping duringin situexperiments.

Mobile Phones in Migrant Contexts: Commercial Discourses and Migrants' Appropriations of ICT in Spain
Authors: Gordano Cecilia
Published: August 2022

As part of the digital technological environment in which contemporary migrations occur, mobile phones constitute a paramount resource for maintaining bonds with geographically scattered family members, as well as for building networks in the original, destination and in-between spaces of migrants’ trajectories. In this context, enterprises have quickly identified a business opportunity in migrants’ cross-border belongings, adapting their business models to transnational family communication (TFC) needs. Focused on Spain, this paper proposes a qualitative approach to migrants' use of mobile phones from a double perspective: Ecuadorian and Moroccan users' accounts, and those of telecom providers’ marketing spokespersons. Preliminary results suggest that spokespersons acknowledge migrants' needs to communicate both abroad and within Spain, although advertising stresses only mobile phone use for TFC. In turn, migrants interviewed face emotional and socio-economic factors that condition their communicative practices in accordance with different intersectional variables, leading them to build complex strategies for the appropriation of mobile phones and other ICT, such as owning multiple SIM cards and visiting cybercafés. This paper argues for a deeper understanding of TFC by partially bringing to the fore the inherent tensions between the discourses of telecom suppliers and the resourceful ICT practices of low-income migrant users.
Mobile Media Architecture: Between Infrastructure, Interface, and Intervention
Authors: Verhoeff Nanna
Published: August 2022

The category mobile media architecture, mobile design between “media” and “architecture” consists of urban interfaces: digital screens used in urban public space, often in conjunction with location-based and/or mobile media technologies. These interfaces intervene temporarily, yet fundamentally, in the city’s built environment. I consider the spatiotemporal logic of two installations that challenge more traditional ideas of spatial design and architecture as fixed, stable, and permanent: the selfie pillar as example of (temporary) urban advertising and narrowcasting, and the art project The Bridge, designed for a traveling screen. These very different examples of urban screens both construct temporary and mobile architectures for spatial extension and connectivity. In so doing they demonstrate an intersection of architectural and cartographic logic. This twin logic is inherent in the intersection of spatial design (architecture) and mobile and location-based technologies that offer tools for spatial orientation (cartography). Between infrastructure, interface and intervention, these forms of mobile media architecture exemplify our current visual regime of navigation.
Marginal Scenes and the Changing Face of the Urban Public Library: The Vancouver Downtown Eastside’s Carnegie
Authors: Mickiewicz Paulina
Published: August 2022

Through an analysis of one of North America’s earliest Carnegie libraries, located in Vancouver, the aim of this article is to question increasingly antiquated discourses of the urban public library as a static cultural institution in order to ascertain how contemporary urban libraries are both representative and generative media institutions that are increasingly central to marginalized urban communities. Marginalized communities, such as those living in Vancouver’s Downtown Eastside, are often overlooked as contributing to the cultural fabric of a city. The Carnegie Library is a site in which precarious, often pre- defined publics, whose members already suffer from established forms of discrimination and exclusion, come together to form a new iteration of the scene (Straw, 2004). I will argue that marginalization, when integrated into a semi-public space and institution such as the Carnegie Community Centre, creates a generative scene that holds the potential of fostering nascent forms of both cultural and political association and education amongst marginalized groups themselves. As a result, the contemporary urban public library emerges as a responsive medium of communication in its own right that is shaped by its siting across distinct urban environments.
News on the move: Towards a typology of Journalists in Exile
Authors: O’Loughlin Conor , Schafraad Pytrik
Published: August 2022

Over the last eleven years, 706 journalists around the world have been forced to flee their homelands as a direct consequence of their work. The aim of this study is to provide insight into how the experience of going into exile has affected the motivations and professional standards of these journalists. The study consisted of in-depth interviews with journalists from five countries who have previously fled their homelands. The study shows that adherence to the truth, a basic tenet of journalism in a liberal democracy, is a cornerstone of professional practice for these journalists. Journalists can be seen to have a bi-dimensional relationship with the truth, considering it an end in itself but also recognising its utility value to help further their democratising goals. Journalists' motivations were also found to be strong towards helping create a better country for their compatriots. Motivations were found to be symbolic or functional. A typology of journalists in exile is proposed. The results are discussed in the context of relevant literature on the roles of journalists in and out of democracies.

Published: August 2022

La implantación global de la telefonía móvil y el espectacular crecimiento del parque de smartphones y tabletas ha animado a la industria de los medios de comunicación a una clara apuesta por el diseño de estrategias para la elaboración de productos de contenidos pensados para los nuevos dispositivos.

Este artículo presenta los resultados de catorce plataformas de medios digitales, 14 de ellas europeas y una de EE.UU. El trabajo analiza las similitudes y diferencias en sus iniciativas con el fin de observar cómo producen contenidos para diferentes canales y gestionan la conversación y el comercio. Para este propósito se ha usado una metodología mixta que combina técnicas cuantitativas y cualitativas de recopilación de la información. El análisis de contenido se centra en los sitios de noticias y sus apps móviles. Los resultados muestran que el contenido de la información en los móviles es principalmente textual pero también incluye fotografías. Hay limitadas posibilidades para la conversación y los proveedores de contenido informativo no se aprovechan de las características específicas de los dispositivos móviles.
