Introduction. Les communs et leurs promesses. Pour une analyse documentée en matière de transition écologique et sociale
Authors: Eynaud Philippe , Feger Clément , Vercher Corinne
Published: July 2024

De par sa position intermédiaire entre gestion publique et gestion privée, l’approche par les communs est porteuse d’un certain nombre de promesses, que ce soit pour une meilleure gestion des ressources, pour une société plus écologique et plus juste, et pour des projets d’émancipation. Dans ce contexte, la recherche académique se doit de poursuivre son travail de connaissance et d’explorer les conditions soulevées par la tenue de ces promesses. Le papier pointe pour cela quatre perspectives de recherche. La première concerne la prise en compte du cycle de vie des communs et les conséquences à en déduire en termes de gestion des ressources partagées. La deuxième est en rapport avec la question du travail et de sa valorisation en vue de pérenniser l’engagement des commoners. La troisième a trait à l’accueil par les cadres institutionnels existants des innovations portées par les communs, et, a contrario, le risque de capture et de dénaturation du caractère inventif par ces mêmes cadres institués. La dernière perspective porte sur les contradictions possibles autour de la gestion des communs naturels lorsque ceux-ci nécessitent le renoncement à certains usages. Le numéro spécial que nous introduisons participent de l’exploration de ces angles mort et contribuent à une analyse documentée afin de consolider le chemin vers une transition écologique et sociale.
Organisation et rémunération du travail dans les communs : les paradoxes du modèle « contributif »
Authors: Louey Sophie , Robert Pierre , Gardin Laurent , Jany-Catrice Florence , Lefebvre-Chombart Amélie
Published: July 2024

Les communs impliquent du travail collectif, mais l’organisation de ce travail et sa rémunération fait l’objet d’un impensé. L’article interroge ces aspects à partir d’une étude du modèle « contributif » développé par des commoner·es lillois·es. Cette étude repose sur une observation au long cours, des entretiens semi-directifs et la diffusion d’un questionnaire auprès du collectif enquêté. Notre étude met en évidence l’importance des activités de communauté dans les communs (Ballon & Veyer, 2020). Dans la mise en application du modèle contributif, ces activités sont pourtant sous-valorisées. Ce mode de fonctionnement a alors tendance à contrevenir aux communs. L’article interroge en définitive les conditions d’une économie des communs pouvant soutenir une organisation du travail coopératif.
A suspension bridges with a fractional time delay: Asymptotic behavior and Blow-up in finite time
Authors: Hajjej Zayd
Published: July 2024

In the present paper, we examine a suspension bridges model subject to frictional damping, a fractional delay term, and a source term. First, we prove the existence of global solutions of the problem. Second, for small initial data, we establish the exponential stability of the system by using the energy method. Additionally, we show that if the initial energy assumes a negative value, the solution blows up in finite time.

Published: July 2024

Peripheral facial paralysis (PFP) causes deficits in muscle and sensory functions of the face due to damage to the facial nerve. In this study, we evaluated the effectiveness of the “Fisiobem” app in rehabilitating patients with PFP through facial mimicry exercises. The app uses the device’s camera to identify the user and measure the range of motion during the exercises, applying the ARKit framework to quantify the intensity of the movements. We conducted a usability study with 34 participants unaffected by PFP, performing mimics with different amplitudes. Results show that glasses did not affect recognition accuracy in exercises such as raising eyebrows, frowning, and closing the eyes tightly. As for wrinkling the nose exercise, glasses impacted higher intensities. As for the beard or mustache, lower lip protrusion, compressing the lips, smiling, showing teeth and blowing out filling cheeks were not affected. However, when smiling with lips together, beard and mustache influenced intensities above 75%. It is important to highlight that this study has limitations, such as the sample size and lack of consideration for ethnic diversity among participants. Future research with larger and more diverse samples is needed to validate and generalize these findings and explore the nuances of interactions between facial features and facial recognition algorithms. Despite these limitations, the approach facilitated by the “Fisiobem” application offers significant benefits, especially for patients with PFP who face challenges in accessing specialized therapists. It allows patients to complement their treatment by performing guided facial mimicry exercises at home. The application helps individuals accurately perform the exercises and effectively track the progress of their rehabilitation.

Published: July 2024

In the rapidly evolving digital age, the need for computational thinking (CT) skills is answered with the introduction of CT-Mobile, an innovative Android-based graphic design application. The app integrates basic computational concepts with graphic design principles, providing a unique platform for users to improve problem-solving, algorithmic thinking, and logical reasoning skills. This study used a research and development (R&D) approach with the 4-D Model (define, design, develop, and disseminate) as a guide. The validity test with experts categorized CT-Mobile as “valid” with values of 0.85 and 0.88 from media experts and material experts. The practicality of this application was rated as “very practical” by teachers (89.67%) and students (86.34%). These findings confirm the significant benefits of CT-Mobile in graphic design learning, both for educators and students. The analysis showed a positive impact on users’ CT ability, reflected by improved problem-solving efficiency and a deeper understanding of algorithmic processes. This study provides valuable insights into the relationship between mobile application development, graphic design education, and the development of CT skills. CT-Mobile emerges as a promising tool to bridge technology, creativity, and cognitive skill development in the digital age.

Published: July 2024

Partindo de uma conceção de formação como via de entrada no ofício, nosso objetivo é discutir o enriquecimento da experiência profissional por meio da análise da atividade de formação pelo trabalho no âmbito do Programa de Educação pelo Trabalho para Saúde (PET-Saúde) – um dos dispositivos de formação para Sistema Único de Saúde (SUS) no Brasil. Para isso, elegemos o método de instruções ao sósia, a partir do qual se propõe um exercício de grupo com o objetivo de explicitar, compartilhar, discutir e desenvolver coletivamente os diferentes modos de exercer a atividade. Quando os dispositivos de formação, como o PET-Saúde, oportunizam a emergência de zonas de desenvolvimento, trabalhadores experientes e novatos se veem juntos na criação de um saber coletivo que forma a todos. Primeiro, abordamos o tema apontando nossas bases teórico-metodológicas, em seguida, situamos brevemente o leitor com relação ao campo da saúde pública e suas políticas de formação. Por fim, a partir dos diálogos que pudemos acionar com as instruções ao sósia, analisamos com os estudantes seu processo formativo em torno do tema das emoções, apostando na ampliação dos recursos para agir como caminho operador de formação e saúde.
Dinâmicas coletivas em experiências de trabalho precário
Authors: Pujol Andrea
Published: July 2024

O artigo analisa a dinâmica coletiva como uma das formas de compreender a precariedade das experiências vividas pelos trabalhadores. Apresenta-se o resultado de dois exercícios analíticos: o primeiro refere-se à exploração da noção de precariedade associada ao conceito de informalidade na evolução do pensamento social latino-americano e como operador para o estudo do trabalho contemporâneo e das experiências de trabalho precário, considerando a dimensão subjetiva; o segundo, refletir sobre os múltiplos significados do coletivo nessas experiências, apresentando os resultados da revisão de pesquisas realizadas na última década. A partir da interação destes caminhos (meta)analíticos, conclui-se que as dinâmicas coletivas ocupam um lugar fundamental na precariedade do trabalho e nas suas possibilidades de transformação.
Los malentendidos de la emancipación. Una investigación ergológica
Authors: Martin Christine
Published: July 2024

Esta tesis analiza las condiciones y posibilidades de emancipación en el trabajo a través de un estudio de cinco años realizado en los puertos petroleros de Fos y Lavera. Se apoya en un enfoque ergológico para responder a las necesidades de la empresa e implementar una política de prevención primaria de los riesgos psicosociales. Al ampliar a continuación el campo de intervención e introducir las "entrevistas dialogadas", la tesis sostiene que la emancipación en el trabajo no sólo es posible, sino esencial para el bienestar de los trabajadores. Así, se propone una perspectiva alternativa a la del sufrimiento y la alienación en el trabajo. Los resultados de esta investigación se sitúan en la intersección de los ámbitos metodológico, filosófico y político.
1987: Publicación de “El desgaste mental en el trabajo : ensayo de psicopatología del trabajo”, por Christophe Dejours, en Brasil
Authors: Zambroni-de-Souza Paulo César , Araújo Anísio José da Silva , Barros Vanessa Andrade de
Published: July 2024

Siete años después de su publicación en Francia, en 1987 se publicó en Brasil la versión en portugués del libro de Christophe Dejours, intitulado “A loucura do trabalho : estudo de psicopatologia do trabalho” (“El desgaste mental en el trabajo : ensayo de psicopatología del trabajo”). Brasil atravesaba entonces un momento de regreso a la democratización, con la valorización de los derechos sociales, incluidos los valores sociales del trabajo. Este escenario hizo con que el libro encontrara un terreno fértil para su acogida. El libro tuvo un gran impacto al proponer una forma de entender la normalidad y la enfermedad en el trabajo desde una perspectiva que no se limitaba a modelos causales simplistas. Asimismo, el papel defendido en el texto sobre los colectivos de trabajo para el desarrollo de la salud y la realización del propio trabajo, alimentó reflexiones que superaron los enfoques solipsistas del problema, sirviendo de soporte a diversas investigaciones e intervenciones en la realidad brasileña.
L’espoir dans l’analyse économique : de l’approche psychologique à une conception transactionnelle et institutionnelle
Authors: Petit Emmanuel
Published: July 2024

Les émotions ont été progressivement intégrées dans l’analyse économique depuis une trentaine d’années. L’espoir demeure cependant une émotion peu mobilisée par les économistes. Aucun des concepts proches couramment utilisés ne correspond à la définition consensuelle que l’on trouve en psychologie. En s’appuyant sur des notions comme les attentes, les aspirations, l’optimisme, les anticipations ou même la confiance, l’économie comportementale fournit les premiers jalons (certes insuffisants) d’une théorie économique de l’espoir. En nous reposant sur la théorie psychologique de Richard Snyder, et en la comparant à l’approche transactionnelle de John Dewey, nous montrons que l’espoir peut être perçu comme un mode de conduite capable de produire une transformation des comportements individuels. En mobilisant la théorie institutionnelle de John Commons – et notamment la notion de « futurité » – il apparaît que la conception transactionnelle de l’espoir approfondit la nature des anticipations dans la théorie institutionnelle.
Talking Back to Virginia Woolf in Her Own Words: Gendered, Racial, and Literary Passing as Forms of Counter-Interpellation in Kabe Wilson’s “Dreadlock Hoax”
Authors: Favre Valérie
Published: July 2024

On 19 May 2014, British multimedia artist Kabe Wilson presented the result of a five-year-long creative endeavour, as he displayed for the first time his literary and artistic recycling of A Room of One’s Own, Virginia Woolf’s landmark 1929 feminist essay. Yet, more than a mere exhibition, Wilson staged a performance art piece entitled “The Dreadlock Hoax” during which the artist, dressed up as Virginia Woolf, proclaimed a speech which questioned our ability to appropriate and negotiate past literary texts and authors. Unbeknownst to his audience, Wilson’s speech was yet another literary recycling, this time of Woolf’s 1937 essay, “Craftsmanship”. Wilson’s performance thus highly relied on both the notion and practice of passing, in terms of gender, race, and language. This article analyses how Kabe Wilson’s multifaceted and multi-scaled creative passing enables him to talk back to Virginia Woolf in her own words, and acts as a form of counter-interpellation through which Wilson reclaims his agency both as a reader and as an artist, while questioning the contemporary relevance of Woolf’s words and recycling them for the twenty-first century.
Charles Bukowski’s Online Reading Community: Safeguarding the Author’s Work by Building a Consensus
Authors: Macaud Amélie
Published: July 2024

This article is a study of a lively online reading community focusing on mid-twentieth century Californian writer Charles Bukowski. For several years, this community of readers, whose behaviors and actions can be compared to that of fans, has tried to right the wrongs of an issue relating to the editing of Charles Bukowski’s posthumous work. They share the belief that John Martin, Charles Bukowski’s former publisher, heavily edited his poems after his death, to the point of making them unrecognizable. An analysis of this forum – more particularly through a close reading of a fourteen-page long discussion thread – will therefore highlight how this community received the posthumous work of their author, slowly but surely managing to build a consensus through the forging of a common enemy.
Les masques de l’animalité : violence et métaphores dans le décor sculpté des jardins de La Granja de San Ildefonso (1721-1746)
Authors: Ruiz Caroline
Published: July 2024

Dans les jardins de La Granja de San Ildefonso, ancien pavillon de chasse transformé en domaine royal au XVIIIe siècle, les animaux sauvages côtoient les animaux sculptés, en marbre ou en plomb. Réelles ou légendaires, ces représentations servent une démonstration de pouvoir en illustrant de diverses manières la domination de l’homme sur la nature. Derrière les masques, de l’enfance, de la mythologie ou de l’animal, se cachent souvent les souverains et leurs adversaires politiques. Placés au service d’une rhétorique de lutte entre le bien et le mal, ces affrontements mettent en scène un détournement ou une justification de la violence exercée sur l’être animalisé, figuré comme féroce voire diabolique.
La realización histórica de la clausura femenina en la Edad Moderna. Entre problemáticas, tensiones y consensos
Authors: Atienza López Ángela
Published: July 2024

Nuestro propósito en este artículo es trabajar con la noción de realización histórica de la clausura femenina durante la Edad Moderna y ofrecer una síntesis interpretativa e integradora a la luz de las aportaciones historiográficas de las últimas décadas. Los dictados tridentinos de clausura estricta se toparon con numerosos factores y dinámicas que la condicionaron y la tensionaron cotidianamente. La clausura, en su realización histórica, fue el resultado de múltiples interacciones entre religiosas, autoridades eclesiásticas y seculares y el conjunto de la sociedad. Fue una encrucijada en la que se dieron cita agencias diversas y en la que se gestionaron, entre tensiones y consensos, los variados intereses y objetivos de los distintos actores y actrices implicados. Atendemos a las dinámicas y problemáticas que condicionaron la clausura y que incidieron en su práctica y en su deriva histórica, desencadenando procesos de apertura y su configuración como una realidad franqueada y franqueable.
El manicomio ¿cárcel o refugio? Perspectivas de estudio a partir del ejemplo del Hospital Nuestra Señora de Gracia de Zaragoza
Authors: Aslot Kassandre
Published: July 2024

El departamento de locos del Hospital Nuestra Señora de Gracia de Zaragoza sirve de punto de enfoque para una evocación del encierro en el tratamiento de la locura en la Edad Moderna. Aunque los textos reglamentarios hacían de la exclusión la condición necesaria a la protección de los dementes y de los otros enfermos, la vida cotidiana reflejada en los archivos judiciales y los testimonios coetáneos revela el carácter ilusorio de dicho encierro que no era radical. Las problemáticas financieras de la institución provocaron frecuentes salidas organizadas por el propio Hospital para permitir el trabajo de los locos; a estas se sumaban las salidas furtivas que la institución, carente del personal necesario, no conseguía evitar. El artículo incide en la dualidad del encierro hospitalario que refleja la complejidad de la relación entre la sociedad y la enfermedad mental en el contexto histórico de la primera modernidad.
No cualquiera es Júpiter para introducirse en una casa-torre. El caso de El Celoso extremeño de Miguel de Cervantes
Authors: Meunier Philippe
Published: July 2024

La configuración cerrada de la casa-torre sevillana del viejo Carrizales incita a leer la novela corta como la reescritura paródica e invertida del fabuloso episodio metamórfico de Dánae y la lluvia de oro. Ya no se trata de la historia de una preñez exitosa sino de la de un ciclo biológico abortado, pese a las estrategias inmateriales y la sexualidad hipertrofiada del virote Loaysa para meterse dentro de la casa-torre donde vive recluida la joven esposa, y seducirla. Así se puede entender por qué en la colección de 1613, la novela del celoso extremeño se sitúa precisamente entre La fuerza de la sangre y La ilustre fregona.
« Rejeter la France » en immigrant au Québec ?
Authors: Mazot-Oudin Antoine , Belkhodja Chedly , Paquet Mireille
Published: July 2024

Depuis le début des années 2000, l’immigration de ressortissants français au Québec, souvent présentée comme privilégiée, est en forte croissance. Toutefois, l’analyse des variations des trajectoires migratoires de Français diplômés et racisés ayant immigré au Québec laisse apparaître le poids des assignations à la fois raciales et nationales vécues par ces migrants dans leurs pays d’origine et d’accueil. Si plusieurs espèrent s’extirper des processus de minoration subis en France malgré leurs qualifications en immigrant vers un pays perçu comme davantage multiculturel, l’entrée dans une telle carrière migratoire les confronte à une « double présence », assignés au fait d’être « français » une fois arrivés au Québec.

Suspendendo a paz nas lutas pela autodeterminação protelada na Palestina e no Saara Ocidental
Authors: Crivelente Moara Assis
Published: July 2024

Este artigo explora o protelamento dos processos diplomáticos favorecendo regimes coloniais no Saara Ocidental e na Palestina, suspendendo a possibilidade da paz emancipatória. Os povos saharaui e palestino lutam pela libertação nacional como realização da sua autodeterminação, mas tal direito tem sido diluído em processos infindáveis de negociações pautadas por estratégias coercivas numa correlação de forças desfavorável para os oprimidos. Com abordagem crítica e marxista ao Direito Internacional e às Relações Internacionais, o artigo parte de uma investigação histórico-materialista desses processos para discutir o problema e as suas alternativas. O objetivo é discutir essas condições históricas, as estratégias de “diplomacia emancipatória” e a “autodeterminação continuada” de saharauis e palestinos, atores em movimento de afirmação como sujeitos históricos através da luta por libertação nacional.

This article argues that Mistry’s unusual use of narrative voice in Such a Long Journey is one of the ways he challenges the conventional dichotomies of private/public, and political/personal. Narrative voice becomes a linguistic equivalent to the political and personal exchanges that occur within and beyond the walls in the novel.
When the Contextual Serves the Textual: Epeli Hau’ofa’s Tales of the Tikongs
Authors: Gillet Nelly
Published: July 2024

Epeli Hau’ofa is a true Pacific writer; in his Tales of the Tikongs, he portrays the imaginary island of Tiko, a fictitious blend of all the islands he personally knows. These twelve short stories about Pacific people and their culture sketch the absurdity of life when taken in the process of ‘development’. Epeli Hau’ofa looks at indigenous responses to politics, love, religion, culture and foreign aid in the context of cultural and economic imperialism. Tales of the Tikongs has long been regarded as a milestone in Pacific literature and establishes Epeli Hau’ofa’s reputation as an acute and delightful observer of his fellow countrymen.
Fictional Contexts, Actual Contexts, and Virtual Contexts in Brick Lane, by Monica Ali
Authors: Král Françoise
Published: July 2024

Monica Ali’s novel Brick Lane chronicles the life of a family from Bangladesh who leaves their home country to settle in England. Like most narratives of exile and migration, this narrative brings into play several contexts: the context in which the text was produced and that where the narrative is set, but also the homeland versus the new country. This paper focuses on the tensions at play in the context represented in the novel. The context is seen as a complex zone of influence where various forces come into play, where global mechanisms produce new frames and settings, which both open up new possibilities and disrupt established patterns, thus unsettling the characters.
Research Methodology for Cost Modelling Development on Smart Living Features Implementation in Malaysian Housing
Authors: Chieng Koh Fung , Mustapa Fara Diva
Published: July 2024

The development of smart living housing in Malaysia, despite its 'people-centric' concept that focuses on resident well-being, faces implementation challenges. Notably, uncertainties related to the monetary implications of integrating smart living features into conventional houses. Consequently, such a situation highlights the need for a decision-making tool – a cost model, to address these uncertainties during feasibility studies. Thus, this chapter proposes the research methodology through a PRISMA-guided literature review to develop the cost model per se. By employing the interpretivism constructivism paradigm, the study utilizes a sequential explanatory mix-method. Quantitatively, an open-ended questionnaire survey identifies the cost drivers, while qualitatively a case studies document survey gathers the cost data. The content analysis legitimizes the claims of both findings for cost modeling development. The research establishes relationships between the cost drivers and cost data, facilitating a monetary implication study to manage uncertainties in Smart Living development.
Genetic Bat Algorithm-Based Multi-Objective Selective Disassembly Sequence Planning
Authors: Xu Zhi Gang
Published: July 2024

The genetic bat algorithm is being actively investigated for its application in the complex multi-objective product selective disassembly sequence planning problem. To broaden the scope of the search space and enhance the overall search efficiency, the traditional bat algorithm has undergone discretization, incorporating a cross-mutation mechanism into the construction of the fitness function model. To assess the efficacy of this novel approach, an industrial mechanical arm is utilized as a representative case study. Upon comparison with the traditional bat algorithm, the proposed method exhibits shorter convergence times across a range of population sizes, thus validating its effectiveness.

Addressing Technical Pitfalls in Pursuit of Molecular Factors That Mediate Immunoglobulin Gene Regulation
Authors: Engelbrecht Eric , Rodriguez Oscar L , Watson Corey T
Published: July 2024

The expressed Ab repertoire is a critical determinant of immune-related phenotypes. Ab-encoding transcripts are distinct from other expressed genes because they are transcribed from somatically rearranged gene segments. Human Abs are composed of two identical H and L chain polypeptides derived from genes in IGH locus and one of two L chain loci. The combinatorial diversity that results from Ab gene rearrangement and the pairing of different H and L chains contributes to the immense diversity of the baseline Ab repertoire. During rearrangement, Ab gene selection is mediated by factors that influence chromatin architecture, promoter/enhancer activity, and V(D)J recombination. Interindividual variation in the composition of the Ab repertoire associates with germline variation in IGH, implicating polymorphism in Ab gene regulation. Determining how IGH variants directly mediate gene regulation will require integration of these variants with other functional genomic datasets. In this study, we argue that standard approaches using short reads have limited utility for characterizing regulatory regions in IGH at haplotype resolution. Using simulated and chromatin immunoprecipitation sequencing reads, we define features of IGH that limit use of short reads and a single reference genome, namely 1) the highly duplicated nature of the DNA sequence in IGH and 2) structural polymorphisms that are frequent in the population. We demonstrate that personalized diploid references enhance performance of short-read data for characterizing mappable portions of the locus, while also showing that long-read profiling tools will ultimately be needed to fully resolve functional impacts of IGH germline variation on expressed Ab repertoires.

Published: July 2024

Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie’s syndrome, is an uncommon postoperative complication of major orthopedic surgery that is characterized by massive colonic dilatation and the potential for substantial morbidity and mortality. Most patients who had Ogilvie’s syndrome had risk factors that could be identified preoperatively, such as immobility, elevated comorbidity, and polypharmacy, prefiguring the frail elderly patient. In modern terms, it is considered a typical orthogeriatric syndrome. In these kinds of patients, we need to be vigilant for its development and judicious in the use of epidural anesthesia. We present an ACPO case in an elderly frail patient with a hip fracture, and we review the available literature to outline clinical characteristics and outcomes. Our patient presented numerous risk factors for developing the syndrome in the preoperative period: nonautonomy in basic and daily living activities, polypharmacotherapy, spinal trauma, and hyposodiemia. In this patient, epidural anesthesia was an additional risk factor. The purpose of this case report is to emphasize the presence of this rare syndrome (1.5% of orthogeriatric patients) in orthogeriatric departments and to identify not only pharmacological, traumatic, and electrolytic risk factors but also those that can be identified even through geriatric evaluation to avoid the use of anesthesiologic techniques and drugs that may have an impact on the prognosis of these patients.

A street called Boom - some glimpses of pioneer Klerksdorp
Authors: Orford J.G.
Published: July 2024

Before the discovery of gold, Klerksdorp was a peaceful village depending for its existence mainly on transport riders, hunters and farmers who used it as a centre for trade. Rumours of promising gold deposits in Klerksdorp in 1888 changed the town overnight into a hive of activity. Towards the end of 1890 the survival of the town and the mining industry was threatened by inefficient mining methods and overcapitalization. However, ruin was averted when a new process of gold recovery was discovered and applied.

Die betekenis van 'n streeksargief vir die Vaaldriehoek
Authors: Van Jaarsveld F.A.
Published: July 2024

The Vaal Triangle comprising Sasolburg, Vanderbijlpark, and Vereeniging has been labelled the Ruhr area or hub of South African industry. Because of the area's relative isolation from the Central State Archives in Pretoria the Town Council of Vanderbijlpark, in conjunction with the University of Potchefstroom's Vaal River branch, has taken the initiative in establishing local archives. Care will be taken to conserve and store documents relating to the whole range of human activities in the Triangle. However, since industry is the central feature of the area, emphasis will be placed on collecting documents of a socio-economic nature. Among other things this will benefit inter-disciplinary research. The co-operation of individuals and institutions is essential if the archives are to be a success.
Paradoxical embolic stroke during catheter-directed thrombolytics in a patient with massive pulmonary embolism
Authors: Ghorbanzadeh Atefeh , Bendel Emily C , Houghton Damon E.
Published: July 2024

Paradoxical embolism represents a critical and potentially fatal complication that can be associated with pulmonary embolism (PE). This case details a unique case of massive PE, further complicated by embolic stroke occurring during catheter-directed thrombolytic therapy. There was no evidence of thrombosis during the initial evaluation with lower extremity Doppler ultrasound, abdominal computed tomography scan, and transthoracic echocardiography. Differentials for the source of the emboli include unrecognized left atrial appendage thrombus, pulmonary arteriovenous malformations, and a patent left foramen ovale. Our findings highlight the complexities and treatment challenges of massive PE.
Effect of different oil extraction techniques for Moringa Peregrina seed on its meal content of glucosinolates
Authors: Abd El-lateaf Hisham A. , Uthe Henriette
Published: July 2024

Background

Moringa peregrina (M.P) is a multipurpose promising tree that grows widely in Asia and Africa’s tropical and subtropical regions. It is generally rich in nutrients especially oil which can be used for edible or nonedible purposes and also rich in protein. However, some anti-nutritional substances, namely glucosinolates (GSLs), remain in M.P meal preventing its utilization in animal or human feeding. These substances though good for the plant to defend against herbivores, cause deleterious effects or are even toxic to animals and humans. GSLs are the most important anti-nutritional substances in M.P seed and meal.

Objective

Accordingly, this investigation aims to use different techniques for oil extraction from M.P seed and their effect on the GSLs content of the meal remaining after oil extraction, then the meal is detoxified to be suitable for using in animal or human feeding.

Materials and methods

In this study, M.P meal was obtained as a by-product left over after oil extraction from moringa seed by different extraction procedures including (hydraulic press, screw pressing, extraction by solvent via Soxhlet, and prepress − solvent extraction at room temperature).The sinalbin, moringin, and total GSLs were determined and identified by HPLC. Detoxification of GSLs was then applied for M.P meal remaining after oil extraction by hexane, using soaking in water followed by a water-washing treatment.

Results and conclusion

The results indicated that sinalbin and moringin are the major dominant GSLs in M.P seed and meal. Moreover, the total GSLs content in the meal that remained after all different oil extraction techniques was significantly higher when compared with their content in the seed. Also, the results showed that there was a significant decrease in the level of total GSLs in M.P meal as a result of the water treatment. It decreased from 941.8±34.14 nmol/mg in defatted meal before water treatment to 23.97±18.31 nmol/mg in residues left after treatment with water for 15 min. Therefore, soaking in water followed by a water-washing treatment is the simplest and most efficient process to remove the GSLs from M.P meal to be suitable for animal feeding.

Backgrounds and objectives

Microglia play a regulatory role in central nervous system inflammatory diseases, such as Alzheimer’s, Parkinson’s, and multiple sclerosis. Natural remedies like black cumin seeds (Nigella sativa) are rich in bioactive compounds that potentially can modulate inflammatory processes in the brain. In the current work, we studied the protective and anti-inflammatory properties of black cumin seed oil (BCSO) and its nano-form on lipopolysaccharide (LPS)-induced neurotoxicity in mice.

Materials and methods

Forty-eight mice were divided randomly into eight groups (n=6), three control groups (negative control, BCSO control, nano-BCSO control), LPS group, and four treatment groups [BCSO+LPS, nano-BCSO+LPS, indomethacin (5 mg/kg)+LPS, BCSO+indomethacin(2.5 mg/kg)+LPS]. At the end of the experiment, the brain tissues were removed for histopathological and biochemical assessments. Malondialdehyde and interleukin (IL)-10 were assessed using enzyme-linked immunosorbent assay while the gene expression of IL-6, toll-like receptor-4, brain-derived neurotrophic factor, nerve growth factor, cyclooxygenase-2, and B-cell lymphoma-2 were assessed by real-time PCR. IL-1β was quantified immunohistochemically along with the histopathological studies of the cerebral cortex of mice brains.

Results and conclusions

In our study, BCSO and its nano-form demonstrated a reduction in LPS-induced neurotoxicity, exhibiting comparable or better anti-inflammatory effects to indomethacin. These treatments significantly elevated the gene expression levels of neuroprotective factors brain-derived neurotrophic factor and nerve growth factor in LPS-treated mice. Pretreatment with BCSO and its nano-form reduced the malondialdehyde levels, in addition to gene expressions of cyclooxygenase-2, toll-like receptor-4, IL-6, and B-cell lymphoma-2. Immunohistochemical analysis indicated a decrease in IL-1β with BCSO and the lowering effect of the nano-form was superior. The histopathological studies corroborated with biochemical and molecular findings, suggesting that BCSO and its nano-form attenuated the inflammation and enhanced the microglial antioxidative and anti-inflammatory status. BCSO could enhance the anti-inflammatory activity of indomethacin, so lower doses of indomethacin with BCSO may be suggested for protecting against the adverse effects of high doses of NSAIDs as gastritis. Consequently, BCSO can serve a potential stimulatory supplement of the immunity for neurodegenerative conditions.

Epidermolysis bullosa (EB) is a heterogeneous group of genetic disorders characterized by the formation of blisters either spontaneously or at the sites of trauma. These heal with post-inflammatory hypopigmentation, scarring, or milia formation. We hereby present a child who presented with widespread hypopigmented atrophic areas, blistering at trauma-prone sites, and nail dystrophy. The significance of this particular case lies in the challenge of distinguishing between epidermolysis bullosa and bullous extragenital lichen sclerosus et atrophicus.

Digital health interventions can overcome geographical barriers and prepare health-care providers for better health outcomes in rural and remote tribal areas, however, it has not been explored among traditional birth attendants (TBAs). A mobile application, “maternal and infant care” (MAI) for capacity building of tribal birth attendants was developed and its quality was evaluated using the Mobile Application Rating Scale for user’s interest in and satisfaction with the esthetics, information, and functionality. Thirteen Android user TBAs with the MAI application were piloted with the MARS checklist. Engagement, functionality, esthetics, and information quality; and one subjective quality scale having 29 items were used. The application was found to be entertaining excellent rating (mean score ± standard deviation) (4.00 ± 0.58), and scored high on performance (3.77 ± 0.93); layout design (3.85 ± 0.90); subjective quality (4.23 ± 0.93), however, scored minimum on interest; gestural design; visual appeal, etc. MAI is a user-friendly, culturally acceptable Android app that can be used for the capacity building of frontline workers.
Regional Disparity and Determinants of Body Mass Index Status among Tribal Women in Eastern India
Authors: Shit Bichitra , Behera Jagannath , Mandal Subhadip
Published: July 2024

The body mass index (BMI) is a commonly employed metric for determining the nutritional status and health risks associated with weight. Tribal women in India face neglect and discrimination in terms of livelihood, nutrition, education, wealth, and health-care access. The study examined 18,697 tribal women from Bihar, West Bengal, Jharkhand, and Odisha, using data from the National Family Health Survey-5. Multinomial logistic regression has been used to determine how the multiple background factors are associated with the BMI of tribal women. The study found that the prevalence of underweight and overweight was 28.5% and 7.6% among tribal women, respectively. Rural tribal women had a higher likelihood of being underweight, whereas urban women were more likely to be overweight. Odisha had a higher prevalence of underweight tribal women, whereas the prevalence is lower in Bihar. The higher prevalence of underweight among tribal women is alarming and necessitates a reconsideration of health infrastructure in the tribal areas.

Published: July 2024

Background:

The closure of educational institutions due to COVID-19 conditions created a situation where contact between students and teachers became almost impossible. It imposed a potential need for adopting alternative learning methods.

Objective:

The objective of this study was to carry out an evaluation of synchronous and asynchronous e-learning methods planned among MBBS students.

Materials and Methods:

An educational interventional study was carried out, including two equipotent academic potential groups of all students of phase 3 part one. Two groups were created (Group A – Synchronous and Group B – Asynchronous) and taught five sessions for each group with asynchronous and synchronous e-learning styles, and perceptions of students regarding learning style were recorded. The data were analyzed using SPSS, and paired t-test and independent t-test were used to compare responses. A descriptive analysis of responses received for perceptions of both learning on a 5-point Likert was carried out.

Results:

Despite the asynchronous group having a higher pretest mean score (33.63 ± 12.03) compared to the synchronous group (25.20 ± 10.1), the post-test mean scores revealed greater improvement in the synchronous group (82.21 ± 12.2) compared to the asynchronous group (81.08 ± 13.32). The study revealed statistically significant higher posttest scores (P < 0.001) in both groups. Asynchronous e-learning was slightly preferable for phase 3 students compared to synchronous e-learning based on the perception given by students.

Conclusion:

Online methods and teaching implemented with the right planning will definitively serve as an alternative in situations like COVID-19. Although these methods cannot replace face-to-face learning, they help develop students’ interest in new learning styles and prepare them for adverse learning conditions.

ABSTRACT

Objectives:

Guo Min decoction (GMD) is a Chinese traditional medicine that can regulate allergy-related symptoms. Although GMD treatment was reported to treat allergy-associated symptoms by regulating the immune response, the rationale between GMD treatment and angiogenesis has not been reported yet. Our objective is to investigate the angiogenesis-modulating activity of GMD.

Materials and Methods:

In this study, we used fluorescence recording, alkaline phosphatase (AP) activity staining, and real-time polymerase chain reaction (PCR) experiments to examine the effects of GMD on angiogenesis in a zebrafish model.

Results:

GMD-treated zebrafish embryos exhibited more intercapillary spaces in the caudal vein plexus (Mock: 11.1 ± 1.8 [n = 20; n: numbers of embryos]; GMD-treated: 16.2 ± 1.9 [n = 20]). AP activity staining showed that treatment with GMD and liquorice (Gan Cao, a component of GMD) induced subintestinal vein outgrowth. However, glycyrrhizin (a component of Gan Cao) had no obvious pro-angiogenic effects on zebrafish. Furthermore, real-time PCR experiments indicated that GMD exposure might be through regulating angiogenesis-related genes (cdh5, nrp1a, and flt1) expressions.

Conclusion:

Based on these observations, we proposed that GMD had pro-angiogenic activity in a zebrafish model, and it might partially be contributed by one of the components, liquorice.
