Unveiling the Role of MX1 and MX2 Gene Expression in Early Pregnancy of Kari Ewes: Insights into INF-tau Signaling and Potential as a Predictive Biomarker for Pregnancy Detection in Domestic Ruminants
Authors: Khan Taimur , haq Ihtesham-ul , Shahab Muhammad , Ahmad Sohail , Khan Sher Hayat , Zheng Guojun
Published: October 2023

Myxovirus resistance (MX) genes are relevant to a family of interferon (IFN)-stimulated genes. In domestic ruminants such as ewes and cattle, the MX genes have two isoforms called the Myxovirus Resistance 1 (MX1) gene and the Myxovirus Resistance 2 (MX2) gene. INF-tau (INFt) is released from embryonic trophoblast cells in the early days of pregnancy and induces expression of MX genes in the uterine endometrium. In the present study, we summarized the relative expression of the MX1 and MX2 genes during the early days of pregnancy in Kari ewes. Blood samples were taken from inseminated and non-inseminated (control) ewes on different days. Peripheral Blood Monocytes (PBMC) were isolated, and with the addition of MX1 and MX2 gene primers, complementary deoxyribonucleic acid (cDNA) was synthesized by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The cDNA was then amplified by rounds of PCR amplification. The amplified product was run on a 2% Agarose gel. The results showed expression of the MX1 and MX2 genes only in pregnant ewes, while no expression was observed in non-pregnant or control ewes. Expression in pregnant ewes was observed on days 14, 16, 17, and 18 after insemination. When comparing the MX1 and MX2 genes, the expression of the MX2 gene was relatively higher than that of the MX1 gene on all experimental days. The result suggested that INF-tau MX genes are expressed during the early days of pregnancy and are involved in the establishment of pregnancy. These results justify the development of this biomarker as a predictive tool for the early detection of pregnancy in ewes and other domestic ruminants.

Authors: Li Huanhuan , Zuo Xiangyi , Wang Chunkai , Yu Wanli , Deng Liwen , Zhao Yu , Wang Xuehu
Published: October 2023

Low Oscillating Shear Stress (LOSS) is known to promote inflammation and atherosclerosis, impacting the phenotype and function of Vascular Endothelial Cells (VECs). The microphthalmia/transcription factor E (MiT/TFE) family of transcription factors regulates autophagy and lysosomal biogenesis in response to internal and external stressors. However, whether LOSS affects the expression of MiT/TFE family members in Human Umbilical Vein Endothelial Cells (HUVECs) has remained unclear. In this study, we utilized qPCR and WB to examine how LOSS influenced the mRNA and protein expression of MiT/TFE family members (MITF, TFEB, TFEC, and TFE3) in HUVECs in vitro. The in vitro findings were further confirmed using immunohistochemistry in a mouse model with a partially ligated carotid artery. Our results showed that LOSS down-regulated the expressions of TFEC and TFE3, while having no impact on MITF and TFEB expressions in HUVECs, the down-regulated expression of TFE3 were validated in the animal model. In conclusion, this study systematically explored the expression patterns of the MiT/TFE family in VECs under LOSS, providing new insights into the molecular mechanisms of abnormal hemodynamics-induced vascular endothelial inflammation-related diseases like atherosclerosis.

The screen whether it is mobile, computer and tablet is a symbol of our modern age. For our children the” digital natives” who have grown up surrounded by digital information and entertainment on screens. Screen Time has become major part of contemporary life. There has been growing concern about the impact of screens on children and young people’s health. So, we plan to study the pattern of mobile phone use and reason behind the mobile use along with the various effects of mobile phones amongst the urban children and follow up after 3 months. Physical inactivity and sedentary behavior have been independently associated with wide range of negative health indicator including obesity, poor cardio metabolic and psycho social health. Total sedentary time can be classified by variety of specific sedentary behavior such as reading, playing quietly, watching television. Mobile phones use which comes under screen time takes almost 1/3rd of total sedentary time. Mobile phone use has become the major part of screen time use. Pediatric organizations recommend no more than 1-2 hour of daily screen time for age 2-5 years and discourage screen time below 2 years of age. Our aim is to systematically examine the pattern of mobile phone use and reason behind the use along with the effect on children in urban population and follow up after 3 months either in person or telephonically.
Musculoskeletal Manifestations of Transthyretin Cardiac Amyloidosis
Authors: Bukhari Syed
Published: October 2023

Transthyretin Cardiac Amyloidosis (ATTR-CA) is caused by the deposition of misfolded transthyretin fibrils, leading to restrictive cardiomyopathy and eventually death if untreated. ATTR-CA is associated with certain musculoskeletal conditions, notably carpal tunnel syndrome, lumbar spinal stenosis, nontraumatic biceps tendon rupture, trigger finger and hip, knee and shoulder arthropathies. These musculoskeletal manifestations could provide a clue and potentially help in the timely diagnosis of ATTR-CA.

Islamic Banking: the Term, Factors of Formation and Prerequisites for Development in Russia
Authors: Tokmakov E. A.
Published: October 2023

The article systematizes the history of the formation of Islamic banking, formulates and proposes an interpretation of this concept, and also structures the main types of services which are provided by Islamic financial institutions. The result of analyse of the external environment is conclusion that the concentration of assets managed by Islamic banks in 2020 has exceeded $1.7 trillion. This concentration has token place due to the accumulation of significant liquidity by the countries of the Middle East and the necessity of diversifying national investment portfolios. It affords them meaningful role in the global financial system. At the same time, the conducted internal Russian socio-demographic analysis shows that more than ten million people who profess Islam in Russia do not have access to Islamic banking products. Based on this, the author of the work has identified fundamental factors, due to which there are no credit institutions in the Russian Federation in the considered market niche. The result of the work is the presentation of banking products and services that can be adapted to the principles of Islamic banking in Russia. General recommendations for their development are presented as well.

Published: October 2023

Due to the increasing demand for water resources worldwide, this commodity and its spatial and temporal properties are of the interest of decision makers and scientists. In this respect, the accuracy in detecting the physical characteristics of the water movement such as velocity and its associated phenomena should be preauthorized in hydraulic studies. Although velocity, as the deriving factor of the water flow, can be determined with the help of theoretical or practical approaches, researchers continuously pushes the limits of science by improving the existing methods to the best. The pitot tube, which is not widely used in open channel hydraulic practices, is one of these methods. In this study, we have addressed a case from design to conducting a set of laboratory experiments. A 3D-printed pitot-tube is designed and used in a set of experiments carried out in an open channel, with different flow rates (three experiments). As a result, the relative error rates were interpreted by comparing the velocity rates obtained with the help of the water level difference in the differential manometer (Vm) and the velocity rates obtained from the flow continuity equation in the open channel (Vo). Results indicated a 50% bias in the experiments, while scatter analysis showed that the associated deviations matches a linear equation.

Analysis of Some Communication-Related Queuing System Modeling and Performance
Authors: Al-Matar Najeeb
Published: October 2023

The paper presents research into the analysis of queuing systems in the context of communication, with the goal of creating precise models and evaluating their efficacy. The importance of queueing systems cannot be overstated in fields as disparate as telecommunications, computer networks, and the service sector. Analyzing how these systems function allows us to better allocate resources, boost performance, and provide a better experience for end users. The main goals are to create mathematical models that precisely capture the queuing behavior and to assess the effectiveness of these models in terms of metrics like queue length, waiting time, and system utilization. To do so, it is necessary to perform an extensive analysis of the relevant literature and theoretical frameworks. The properties of communication-related systems are examined, and many queuing models, including the M/M/1, M/M/c, and M/G/1, are modified accordingly. In addition, simulation methods are used to verify the accuracy of the suggested models and assess how they would fare in practical applications. The research yields useful information on the dynamics of queuing systems used in the field of communication. They show how changes to the arrival rate, service rate, and number of servers affect the system's most important performance indicators. Different scheduling policies, routing tactics, and resource allocation methodologies are also investigated to determine their impact on system performance.
A shifting language-scape
Authors: García-Barroso Lorena , Torres-Vélez Víctor M.
Published: October 2023

By engaging the literature of transnationalism and Latinx studies with that of multiliteracies, this article contends that the cultural and linguistic complexities experienced by Spanishspeaking populations in global cities can be better addressed by a multiliteracies framework. We argue that using multiliteracies to teach adult learners can challenge negative linguistic and cultural stereotypes in the classroom. We conducted a qualitative study with at-risk adult learners. Using a TV show, we developed a series of pedagogical interventions and exercises to encourage cultural and linguistic pride to mitigate pervasive negative stereotypes around Latinx in the US. We contend that the development of language policies needs to engage the linguistic and cultural complexities experienced by Spanish-speaking people within the diasporic communities of global cities. The study was conducted at Hostos Community College in the Bronx, NY. The study shows that our pedagogical interventions mitigate negative linguistic and cultural stereotypes.
Role of iron-carbon interactions in the release of greenhouse gases from permafrost soils
Authors: Kappler Andreas , Patzner Monique , Chauhan Ankita , Voggenreiter Eva , Wunsch Katrin , Bryce Casey , Joshi Prachi
Published: October 2023

As permafrost thaws, vast stocks of organic carbon which accumulated over long time periods within these soils are vulnerable to microbial decomposition and carbon may be released as the greenhouse gases CO2 and CH4. The release of these greenhouse gases from permafrost systems is expected to lead to runaway positive feedbacks. The timescale and magnitude of the permafrost-climate feedback is highly uncertain as knowledge gaps remain regarding the rate of decomposition of permafrost organic carbon. These knowledge gaps stem, in part, from lacking understanding of the association between organic carbon (in the form of natural organic matter) and minerals, especially high surface area iron (oxyhydr)oxide minerals. This iron-carbon association has the potential to stabilize the organic matter, lower its bioavailability and therefore protect it from biodegradation – representing a “rusty carbon sink”. In this work, we investigated the coupling of iron and carbon cycles in permafrost peatlands and its effect on greenhouse gas release. Our initial work showed that up to 20% of the organic carbon in intact permafrost sites may be associated with iron(III) (oxyhydr)oxides and thereby protected from microbial decomposition. We then found that at the onset of thaw, this association is broken down, likely due to the microbial reduction and dissolution of iron(III) minerals. As a consequence, the previously protected organic carbon is thus released and becomes bioavailable. Using microbiological and molecular biological tools as well as greenhouse gas measurements, we linked this breakdown to an increase in the abundance of methanogenic microorganisms and concentrations of methane. Additional work also suggests that part of the released organic carbon may re-associate with dissolved iron in thaw ponds to form flocs. Currently, we are investigating the molecular composition of organic matter with high-resolution mass spectrometry techniques (FT-ICR-MS) as it undergoes these redox processes with the goal of linking bioavailability to composition. We complement our studies with laboratory microbial enrichment and isolation approaches and microbial community analyses to determine the microbial key players controlling iron(III) reduction and the potential for subsequent microbial Fe(II) oxidation. Collectively, the results of this project suggest that upon thawing, organic matter previously associated with minerals is mobilized and is likely susceptible to microbially mediated release as CO2 and CH4.
Microbial pyrite formation: mineral morphology and precipitation kinetics
Authors: Mansor Muammar , Višić Hrvoje , Runge Eric , Shuster Jeremiah , Fischer Stefan , Kappler Andreas , Duda Jan-Peter
Published: October 2023

Pyrite (FeS2) is a mineral of wide interest due to its importance in the biogeochemical cycling of Fe and S, which is tied to those of carbon and other trace metals and nutrients. The mineral itself has potential applications as biosignatures, for environmental remediation and as semiconductors. Despite being a common authigenic mineral in sedimentary environments, most laboratory-based experiments have failed to form pyrite in microbial cultures at ambient temperatures. To fill this knowledge gap, we have employed cultivation-based approaches, using different combinations of microorganisms (Fe(III)- and S0-reducers; S0-disproportionaters) and initial Fe and S sources to identify the conditions that are optimal for pyrite formation. Scanning electron microscopy (SEM), Raman spectroscopy and X-ray diffraction (XRD) demonstrate that pyrite is not formed within ~3 years at circumneutral pH when oxidants (e.g., Fe(III) minerals, elemental sulfur, S0) are exhausted. In contrast, pyrite is formed within months when S0 and Fe(III) minerals are both present. The precipitation timescale is consistent with those expected in sedimentary environments Mansor and Fantle 2019), albeit some natural pyrite framboids are expected to form even faster Rickard 2019). The pyrite crystals formed in our experiments are in the low micrometer range, with either a spherical or euhedral morphology depending on the initial crystallinity of the supplied Fe(III) minerals. Framboids are not formed in our system, perhaps due to the relatively slow precipitation kinetics. Time-based sampling indicates mackinawite (FeS) as the first product, with rare (and minor) detection of greigite (Fe3S4) and vivianite [Fe3(PO4)2.8H2O]. We hypothesize that pyrite formation and growth proceed mainly from transformation of precursor minerals, with potential contributions via dissolution-precipitation and/or particle attachment pathways. Our preliminary study is the first step in optimizing a system for microbial pyrite formation, with the intention of investigating the properties and the reactivity of the mineral with implications for biosignatures, environmental remediation and industrial applications.
As green infrastructure, linear semi-natural habitats boost regulating ecosystem services supply in agriculturally-dominated landscapes

Published: October 2023

Semi-natural linear landscape elements, such as hedgerows, are vital structures within agricultural landscapes that have an impact on ecosystem processes and support biodiversity. However, they are typically omitted from green infrastructure planning, which could lead to significant undervaluing of landscapes and their multifunctionality in terms of ecosystem service supply. Using the InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) model suite, we tested the effects of additionally including semi-natural linear landscape elements on the model outcomes for crop pollination, nutrient regulation, erosion regulation and water flow regulation ecosystem services supply. The results showed that linear semi-natural landscape elements contribute positively to the landscape’s multifunctionality. Small changes have been identified for water flow regulation, whereas, considering both spatial extent and magnitude of the changes, the greatest changes have been found with respect to the supply of pollination and nutrient regulation. Direct proximity of the linear elements had the greatest effect on ecosystem service supply, in particular with regard to pollination. Based on our results, a more pronounced consideration of semi-natural linear landscape elements as an important element of green infrastructure is advisable.

L’homme de Yama. Traitement de la « fracturation » de soi
Authors: Hiers Svetlana
Published: October 2023

« L’homme de Yama. Traitement de la fracturation de soi. » Notre réflexion porte sur l’homme ordinaire dans le collimateur de l’Histoire, à partir de la psychothérapie d’un demandeur d’asile politique et de sa femme. L’homme a été enlevé et détenu dans une prison secrète à l’époque de la seconde guerre de Tchétchénie. Leur histoire familiale dramatique est spécifique à ce conflit où l’État russe a instauré un système de violence et de peur, dont la pierre angulaire était la torture. Ces enlèvements font écho au destin de leurs grands-parents, déportés avec le peuple tchétchène en janvier 1944. Les questions qui nous animent sont : comment intégrer l’expérience de l’innommable dans la vie de famille ? Comment leur récit s’inscrit-il dans l’histoire transgénérationnelle ? Comment soigner la psychose post-traumatique, quand la cruauté est l’expression du pouvoir d’un régime totalitaire ?
Écologie et thérapie familiale : prendre soin des familles et de l’institution
Authors: Gianèse-Madelaine Catherine
Published: October 2023

« Écologie et thérapie familiale ; prendre soin des familles et de l’institution ». Nous vivons une évolution importante dans les orientations et les pratiques des institutions. Dans ce contexte de crise sanitaire, les appuis et les repères sont ébranlés, tant pour les enfants et leurs parents que pour les soignants. Les capacités de contenance en sont bien fragilisées. L’environnement semble traversé par un bouleversement général ; le sentiment de sécurité individuel et collectif est ébranlé. À l’image de ce qui se pratique en agriculture biologique, l’auteur propose l’approche groupale et psychanalytique de la famille comme voie « à contre-courant » ! Respecter les mouvements du groupe familial et ses mécanismes de défense, l’accompagner dans la recherche de ses propres capacités de croissance, tenir compte de son rythme d’évolution, telles seraient les principales modalités de ce travail un peu marginal au regard des évolutions actuelles. Prendre soin à plusieurs des liens humains comme de la nature demande du temps et de l’attention. Une vignette clinique illustre ce long travail fertile.
Intérêt de la sculpture en thérapie de couple
Authors: Nguyen Pascal
Published: October 2023

« Intérêt de la sculpture en thérapie psychanalytique de couple. » La sculpture est un outil de médiation groupal corporel qui permet une relance du travail thérapeutique par un travail de figuration. Présenté ici dans le cadre d’une thérapie de couple, nous allons essayer d’identifier le moment auquel le thérapeute va y avoir recours et les aspects transféro-contretransférentiels qui y sont mobilisés. Il apparaît que le désir du thérapeute d’introduire cet outil s’inscrit dans une évolution du néo-groupe et notamment au moment de l’émergence d’un matériel corporel conjugal. Le processus de symbolisation primaire remobilisé nous semble s’organiser à un niveau archaïque pour constituer une entité co-sensorielle que nous nommons corps familial.
Engrammes corporels encapsulés et narration somatique – Intégration de la mémoire corporelle dans la technique psychanalytique
Authors: Leikert Sebastian
Published: October 2023

Avec comme point de départ l’observation qu’une bonne intégration du soma et de la psyché manque souvent dans notre travail avec des analysants sévèrement perturbés, deux concepts sont discutés, qui se concentrent sur des constellations de matériel inconscient encodé corporellement nécessitant une forme spécifique de perlaboration. Le concept d’engrammes corporels encapsulés est exposé, se référant à des structures défensives tournant autour de l’inhibition ou de la désorganisation d’une impulsion corporelle affective. Le déséquilibre qui surgit ainsi est perçu comme un corps étranger au sein du self corporel. Ces engrammes sont répétitifs et ne sont pas susceptibles d’être transformés symboliquement. Des parallèles sont discutés entre les engrammes corporels encapsulés, les objets autistiques (Tustin, F. (1980). « Autistic Objects. » International Review of Psycho-Analysis 27  : 27-39) et la théorie freudienne de l’inhibition (Freud, S. [1926]. Inhibition, symptôme et angoisse. OCF-P. XVII  : 113-205). Les sensations corporelles émergeant dans la chaîne associative sont comprises comme des tentatives de communiquer, afin de débloquer les engrammes encapsulés. Dans un processus appelé narration somatique, ces perceptions sont contextualisées avec d’autres sensations corporelles. La perlaboration de ce matériel dans le transfert et le contre-transfert est décrit à la lumière des concepts de Lombardi (Lombardi, R. [2017]. Body-Mind Dissociation in Psychoanalysis – Development after Bion . New York : Routledge). Deux cas cliniques précèdent la discussion théorique.

Published: October 2023

Présentation de l’article par les traducteurs 3  : À l’occasion du décès de Philip Bromberg qui était un collaborateur et ami personnel de l’auteur, celui-ci présente le personnage et expose ses idées originales sur la pratique analytique. Il s’agit du courant dit de l’école interpersonnelle, dont l’inspirateur est Levenson. La menée de la cure est ici centrée moins sur l’élucidation des conflits internes que sur le vécu de l’expérience de rencontre avec le patient. Le concept de trouble dissociatif de l’identité est central ; il correspond à un mécanisme de défense primaire, sorte de mise en suspens de l’existence du soi, face au traumatisme précoce. Un autre concept original est celui de soi multiple, une multiplicité normale des états du soi.
L’éducation des adultes et les enjeux des sciences et technologies pour tous face aux défis de la catégorisation scolaire au Cameroun
Authors: Temkeng Albert Étienne
Published: October 2023

L’éducation des adultes en général et les apprentissages scientifiques en particulier sont influencés par des déterminants cognitifs, affectifs et conatifs dont l’appréhension consiste à évaluer l’empreinte de la formation scolaire initiale dans les choix des adultes à reprendre les études. En effet, la démarche de reprise d’études s’inscrit en droite ligne des principes fondamentaux de la théorie du rapport au savoir (Charlot, 2021), rapport à la fois singulier et social, fruit des activités des générations antérieures qui permettent la sédimentation de l’apprenant au monde. À cet effet, dans le cadre de nos recherches doctorales, l’enquête sur les enjeux de la reprise d’études au Cameroun (Temkeng, 2020) a révélé que, victimes des effets durables de la catégorisation scolaire passée, les adultes en général et les femmes en particulier préfèrent poursuivre leur formation dans leurs disciplines, filières et spécialités non scientifiques. Leur attitude peut être mise en relation avec un Sentiment d’Efficacité Personnelle (SEP) insuffisant pour les autres matières. Néanmoins, les jeunes adultes, et particulièrement les hommes, sont très engagés dans les études scientifiques, au regard de l’acculturation scientifique globale de la société et des défis incontournables qu’elle implique. Malheureusement et malgré les injonctions aux sciences pour tous, le système socioéducatif n’est pas toujours incitatif. Par conséquent, il est essentiel de trouver les moyens psychopédagogiques et les stratégies socioéducatives modernes et efficaces pour amener les apprenants à transgresser la catégorisation scientifique pour s’investir durablement en sciences.
Accompagner le développement professionnel des entraîneurs pour optimiser la dynamique de leurs interactions avec les athlètes : les cas des entraîneurs de badminton
Authors: K/Bidy Julie , Escalié Guillaume
Published: October 2023

Notre étude cherche à comprendre l’activité des entraîneurs eu égard à sa portée sur celle des athlètes. Elle s’inscrit dans un programme de recherche en anthropologie culturaliste permettant de conceptualiser les significations que deux acteurs associent aux expériences qu’ils vivent, mais également d’apprécier le niveau d’intersubjectivité entre eux. Les résultats d’une première étude ont montré que les interactions entraîneur-athlètes étaient régulièrement le lieu de désaccords pouvant mener à une collaboration improductive. Une étude à visée transformative a été menée pour permettre à l’entraîneur de tendre vers un plus haut niveau d’intersubjectivité avec son athlète. Méthodologiquement, après l’enregistrement audio-vidéo (EAV) d’une séance d’entraînement suivi d’un entretien d’autoconfrontation (EAC) mené avec l’entraîneur puis l’athlète, nous avons mené un second entretien dit « transformatif » avec l’entraîneur. Confronté à l’EAC de l’athlète, il devait interpréter les désaccords observés. L’EAV d’une seconde séance suivie des EAC de l’entraîneur et de l’athlète a été mis en place pour repérer un possible processus de développement chez l’entraîneur. Malgré certaines résistances qui accompagnent ce processus réflexif, les résultats montrent que l’accès au vécu de l’athlète et plus particulièrement le constat des désaccords de signification constituent une occasion pour l’entraîneur de s’engager dans une activité réflexive, source de développement professionnel.
Analyse de l’activité d’apprenants dans un dispositif visant le développement d’apprentissage tactique en badminton
Authors: Royet Thomas , Mascret Nicolas , Vors Olivier
Published: October 2023

L’intérêt de la dimension tactique des apprentissages en sports de raquette a été maintes fois démontré scientifiquement : au stade conatif « contextuel » en badminton (Dieu, 2012), lors de la phase « exploratoire » en tennis de table ( e.g ., Sève et al. , 2003). Professionnellement, les textes officiels (AFC, Programme lycée, 2019) comme la littérature spécialisée ( e.g ., Joing & Jospin, 2013) insistent sur la notion de choix tactique. Les rares études en badminton montrent une préoccupation principalement affective plutôt que tactique en lien avec l’histoire de match (Guillou & Durny, 2008). Il est également démontré divers décalages entre les prescriptions des enseignants et l’activité réelle des élèves lors du jeu du « Banco » (Rossard, Testevuide & Saury, 2005) ou en situation coopérative (Guérin et al. , 2004 ; Rossard & Saury, 2009). L’enjeu de notre étude compréhensive est d’analyser l’activité typique d’étudiants non spécialistes dans le dispositif scolaire d’apprentissage tactique en badminton « Les maîtres du jeu » (Deutz D’Arragon, Mascret & Vors, 2020) selon le programme de recherche du « cours d’action » avec l’objet théorique « cours d’expérience » à partir du signe tétradique (Saury et al. , 2013 ; Theureau, 2015). Les trois participants de niveaux différents de 18 ans sont des étudiants non optionnaires de badminton, en première année de STAPS. Le recueil de données s’est fait en début et en fin de séquence (leçons 1 et 12) avec les données remplies par l’observateur sur la fiche d’observation, l’espace de jeu où les volants sont envoyés et les données de verbalisation des joueurs lors de six séances d’entretiens d’autoconfrontation explicitant le point de vue des joueurs lors de 12 sets. Notre étude compréhensive a visé à analyser la dynamique des apprentissages tactiques d’étudiants placés dans le dispositif « Les maîtres du jeu » au travers de l’analyse de leur cours d’expérience. Les apprentissages tactiques ont été identifiés au travers du cours d’expérience des joueurs. Notre discussion portera sur une réflexion sur les usages des dispositifs d’apprentissage tactique et sur des pistes professionnelles.

Published: October 2023

Purpose:

To evaluate the visual outcome, light distortion index (LDI), and quality of life (QoL) of patients implanted with two complementary intraocular lenses (IOLs) to treat cataract and presbyopia.

Methods:

Twenty-seven consecutive patients with cataract were treated with the implantation of the Artis Symbiose Mid (Mid) IOL (Cristalens Industrie) in the distance-dominant eye and the Artis Symbiose Plus (Plus) IOL (Cristalens Industrie) in the contralateral eye following phacoemulsification. The primary objective was to ascertain the monocular and binocular defocus curves. Secondary endpoints included uncorrected distance visual acuity, corrected distance visual acuity, uncorrected intermediate visual acuity, and distance-corrected intermediate visual acuity at 90 and 70 cm, uncorrected near visual acuity and distance-corrected visual acuity at 40 cm, contrast sensitivity, LDI with a halometer, stereopsis, and patients' QoL with the validated Visual Function Index (VF-14) questionnaire. These measurements were collected in two visits, at 4.14 ± 3.13 and 10.30 ± 3.14 months postoperatively.

Results:

Statistically significant differences in the monocular defocus curves were found at the defocus steps of −1.00, −1.25, −1.50, −1.75, −2.50, −2.75, −3.00, −3.50 diopters and the −4.00 diopters (
P
< .050). The mean binocular defocus curve was 0 logMAR or better from the +0.50 to the −2.50 D defocus steps. Contrast sensitivity was within normal values. The LDI was 12.57 (6.61)% for the Mid eyes, 14.99 ± 5.70% for the Plus eyes, and 10.36 ± 4.42% binocularly. The patients' stereopsis was 40.0 (12.5) arc-seconds. The QoL score was 95.99 (7.14) at 10 months.

Conclusions:

The implantation of the Artis Symbiose IOLs was a safe and effective treatment for presbyopia compensation in patients with cataract. Both IOLs are complementary and may produce a binocular depth-of-field of 3.00 diopters over 0 logMAR when used together.

Efficacy and Safety of Implantable Collamer Lens V4c Implantation in 1,834 Myopic Eyes for 1 Year of Follow-up
Authors: Du Jingxiao , Zhou Wenkai , Zhao Ting , Qian Tianwei , Lu Yi , Li Haiyan , Zhang Zhihua , Lian Jingcai
Published: October 2023

Purpose:

To evaluate visual outcomes of patients with myopia after EVO Implantable Collamer Lens (ICL) (STAAR Surgical) implantation and predict risk factors of postoperative vault abnormalities.

Methods:

In this single-center, retrospective analysis, 1,834 eyes of 926 patients with myopia who underwent EVO ICL implantation were recruited between 2020 and 2021. Patients were followed up for 1 year, during which surgery outcomes were evaluated. In addition, 31 eyes with vault abnormalities who underwent secondary surgery were enrolled to form a generalized linear model, which aimed to predict risk factors contributing to vault abnormalities.

Results:

At the final follow-up visit, safety and efficacy indexes were 1.12 ± 0.17 and 1.10 ± 0.19, respectively, and there was no statistical significance between the low and high myopia groups. Furthermore, 79.18% of eyes achieved a residual spherical equivalent within ±0.50 diopters. Except for the temporary elevation of intraocular pressure at 1 week postoperatively, IOP and endothelial cell density remained stable during follow-up visits. The rate of postoperative adverse events was 21.97% and most adverse events were transient. Vault abnormalities accounted for the majority of complications (9.54%). Results of generalized linear model showed that age was a risk factor for postoperative vault abnormalities, and the anterior chamber depth served as a protective factor (
P
< .05).

Conclusions:

Visual outcomes of EVO ICL implantation were satisfactory in safety and efficacy indexes in both the low and high myopia groups for 1 year of follow-up, with acceptable stability in postoperative spherical equivalent, intraocular pressure, and endothelial cell density. This study emphasized cautious ICL size selection for older patients and those with shallow anterior chamber depth.

Thinking Together: Advising as Collaborative Deliberation
Authors: Habgood-Coote Joshua
Published: October 2023

We spend a good deal of time thinking about how and when to advise others, and how to respond to others advising us. But philosophical discussions of the nature and norms of advising have been scattered and somewhat disconnected. The most focused discussion has come from philosophers of language interested in whether advising is an assertive or directive kind of speech act. This paper argues that the ordinary category of advising is much more heterogenous than has been appreciated: it is possible to advise by asserting relevant facts, by issuing directives, by asking questions, and by other kinds of adviceless advising. The heterogeneity of advising makes speech act-theoretic accounts of advising look like accounts of special cases, which motivates us to look elsewhere for an account of what advising is. I suggest that we think about advising as a distinctive species of joint practical thinking, which I shall call collaborative deliberation, and show how our need for a concept to pick out this kind of joint activity emerges from our practical needs as deliberators. This view helps to illuminate a number of puzzling features of advising, and offers some guidance to be better at advising and at being advised.
Movimiento indígena, ecologías y contrahegemonía en Nayarit (México)
Authors: Rodríguez Carlos Rafael Rea
Published: October 2023

Este artículo analiza el movimiento indígena en Nayarit, México, abordando algunas de las luchas de resistencia producidas por los pueblos originarios que conforman este movimiento, así como la creación de capacidades contrahegemónicas para enfrentar la dominación de la modernidad capitalista-colonial-heteropatriarcal. Se concluye que la articulación de este movimiento social, permite recuperar, actualizar y potenciar elementos ontológicos y epistemológicos que han persistido a lo largo de siglos y que se mantienen, reconfigurados, como plenamente contemporáneos. Este estudio se basa en la teoría de las epistemologías del Sur, propuesta por Boaventura de Sousa Santos, particularmente en la operación de la sociología de las emergencias. El trabajo se efectuó a partir de una investigación bibliográfica y del análisis de pronunciamientos, así como de mesas redondas, discursos, notas periodísticas y entrevistas.
Exploring Communication Skills, Transformational Leadership, and Intergenerational Climate in Educational Institutions
Authors: Demirdağ Seyithan , Efe Ayşe Kalo
Published: October 2023

This chapter aims to examine the relationship between communication skills according to teacher perceptions and transformational leadership behaviors of school administrators with intergenerational climate in the instructional environment. Developments, changes, and innovations in scientific, social, and technological fields around the world have brought about significant changes in social life. The accumulation and production of knowledge resulting from the rapid progress in these fields has made it necessary for societies, institutions, and organizations to adapt to the changes and developments that occur. Educational institutions, which play a significant role in this necessity, must closely monitor global changes and developments by updating themselves. This is because the education system of a country or a society, which is a significant contributor to its progress, and the schools, which are the fundamental components of this system, contribute to the development of societies by following scientific, social, cultural, and technological advancements.
Minority Groups and Street Children Listening and Inclusion
Authors: Julien Gabriel
Published: October 2023

Who are minorities? Who are street children? Are they important? Is there merit in understanding them? This chapter tried to address these cardinal issues. It is highly convoluted and intricate to arrive at a precise definition for minorities since, according to Wikipedia, it cannot be only comprehended in terms of demographic sizes within a specific population. It is interesting to note that previous studies revealed several definitions for street children. Although it is complex to offer precise definitions for minorities and street children, it must be acknowledged that there is a nascent body of research and literature. When this non-empirical research was undertaken, there was no tangible evidence to demonstrate a sound understanding of minorities and street children.
Compressive Stress-Strain and Rebound Resilience Properties of Deproteinized Natural Rubber Latex Foam

Published: October 2023

Deproteinized natural rubber (DPNR) latex is a modified version of natural rubber (NR) latex that is hypoallergenic and odorless when used in products. However, due to the lack of studies in this field, there are relatively few DPNR latex foam products to date. Our laboratory has developed a novel manufacturing technique that involves a heat-enzymatic reaction followed by a concentration procedure to generate DPNR latex directly from freshly tapped latex and to manufacture a novel DPNR latex foam using the Dunlop batch foaming procedure. To investigate the mechanical properties of the foam, ball-rebound resilience studies and compression tests were conducted on DPNR latex, commercial grade polyurethane (PU) and polyurethane memory (PM) foams as a comparison. Compressive stress-strain study revealed that the hysteresis loss ratio of DPNR latex foam, PU foam, and PM foam is 0.19, 0.66, and 0.86, respectively. DPNR latex foam exhibits the lowest hysteresis loss ratio due to its elastic behavior thus able to store a high amount of energy when under compressed. On the other hand, the rebound resilience of DPNR latex foam, PU foam, and PM foam is 74%, 29%, and 9%, respectively, indicating that DPNR latex foam has the highest rebound resilience. The resilience property is correlated with the elasticity, dimensional stability and durability of foam materials. Thus, DPNR latex foam is suitable for heavy-duty cushion applications including seats for transportation industry.
Clinical and radiological characteristics of cerebral vein thrombosis: a retrospective study
Authors: Almegren Mosaad
Published: October 2023

Cerebral vein thrombosis (CVT) is a rare type of stroke that can present with a wide range of symptoms and signs, making it challenging to differentiate from other neurological conditions. Therefore, this study aimed to evaluate the clinical characteristics and risk factors of cerebral vein thrombosis patients. This descriptive analysis included 103 CVT patients registered in two centers, one in Saudi Arabia and one in Oman. The study covered all patients who presented to these centers from 2006 to 2020 with a confirmed diagnosis. Out of the 103 CVT patients included in the study, 32% were male, and 68% were female, with a mean age of 39 years. Headache was the commonest presenting symptom, followed by seizures. Identifiable risk factors were observed in most patients, with oral contraceptive pills and pregnancy being the most prevalent risk factors. The transverse sinus was the most commonly involved sinus, followed by the sagittal sinus, while intracerebral bleeding was present in 22% of patients. CVT is an uncommon type of stroke that affects individuals in the middle age group, particularly child-bearing age females. The clinical characteristics of CVT vary, with headache being the most prevalent clinical presentation, and its diagnosis requires a high degree of clinical suspicion.

This article presents a systematic review and analysis of grey literature to identify and address gaps in knowledge regarding the role and influence of bystander activation on pre-hospital emergency care (PEC) response time. We conducted a systematic search for full-text articles published since 2000 in Web of Science, PubMed, Science Direct, and Google Scholar databases. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, using “pre-hospital emergency care response time” and “bystanders” as search keywords. The risk of bias was assessed using the ROBINS-I tool. Our analysis included forty-six relevant studies meeting the inclusion criteria. However, we observed that many studies were poorly reported, posing risks of selection and detection biases. Additionally, we identified methodological and study design weaknesses in five studies. Given the critical role of PEC services in saving lives and preventing medical complications, the timely provision of these services is paramount. Bystanders play a central role in activating emergency medical services (EMS) and providing cardiopulmonary resuscitation. Prompt calls to EMS by bystanders resulted in reduced PEC response times, improved survival chances, and better neurological outcomes, particularly among out-of-hospital cardiac arrest patients. There is substantial evidence that prompt bystander activation of EMS significantly reduces PEC response times, thereby saving lives and strengthening existing PEC systems. However, further research is necessary to accurately assess the impact of different interventions aimed at enhancing bystander activation of EMS and reducing PEC response times.
