Entre éthiques du devoir et éthiques du bonheur, une troisième voie : l’éthique de l’imitation
Authors: Ide Pascal
Published: April 2024

Il est usuel de distinguer les éthiques, qu’elles soient philosophiques ou théologiques, en deux groupes : les éthiques téléologiques (l’eudémonisme et le conséquentialisme) et les éthiques déontologiques (l’éthique du devoir et les éthiques procédurales). Après en avoir souligné la valeur et les limites, l’article propose une troisième voie : la morale de l’imitation. Il montre que celle-ci se fonde autant dans la Révélation que dans l’expérience quotidienne, la philosophie et les sciences. Il cherche à articuler ces trois morales du bonheur (et de la vertu), de la loi et du modèle – faisant de celle-ci une médiation entre les deux premières –, et répond aux objections habituellement opposées à l’éthique mimétique.
Un grand thomisme de « l’être comme don » : la métaphysique de Ferdinand Ulrich (2023)
Authors: Tourpe Emmanuel
Published: April 2024

On connaît très peu dans le monde francophone l’extraordinaire développement qu’a connu le thomisme dans les pays de langue allemande. Un fossé sépare très nettement l’approche principalement historiciste de l’Hexagone, ou la méthode épistémologique belge, de la forme très spéculative qu’a pris le thomisme outre-Rhin.
Les presses dans le mandat Français en Syrie et au Liban : vers la création d’un espace public mandataire
Authors: Figeac Jean-François
Published: April 2024

La presse connaît un vif essor dans le contexte du mandat français en Syrie et au Liban. Moyens de soutenir ou de critiquer l’administration de Beyrouth, les journaux deviennent des organes indispensables de politisation alors que le nationalisme entre en concurrence avec les particularismes confessionnels. Dialoguant avec d’autres espaces publics, qu’ils soient métropolitains, coloniaux ou liés à la diaspora syro-libanaise, cette presse, loin de fonctionner en vase clos, s’insère dans des logiques globales.
François-Henri Schneider et son empire typographique au Tonkin fin du XIX e - début du XX e siècle
Authors: Lê Thu Hằng
Published: April 2024

François-Henri Schneider était la figure la plus importante de l’imprimerie et de l’édition au Tonkin (le nord du Vietnam) au début du XX e siècle. Fonctionnaire, il démissionna pour construire « son empire » qui deviendrait incontournable grâce à ses bonnes relations avec les autorités coloniales et son réseau. C’est à lui que devait la création de l’imprimerie, l’édition et la presse en quốc ngữ (écriture romanisée du langage vietnamien) dans la contrée où la culture chinoise restait bien enracinée. Homme d’affaires visionnaire, il sut toujours attacher ses propres intérêts aux projets de propagande des autorités coloniales en mettant à la position de celles-ci de différents moyens : création de journaux d’informations en quốc ngữ , manuels de quốc ngữ , traduction des œuvres littéraires françaises et chinoises en quốc ngữ… Ce travail lui tenait à cœur parce que lui-même était un fervent promoteur de cette écriture romanisée. Toute la première génération de journalistes, éditeurs et traducteurs tonkinois était liée directement ou indirectement aux entreprises de François-Henri Schneider.
Promouvoir l’action de la France en Indochine : la presse à l’Exposition de Hanoï (novembre 1902 - février 1903)
Authors: Puyo Jean-Yves
Published: April 2024

Pour faire la promotion de l’Indochine, ouverte à la colonisation française à fin du XIX e siècle, son gouverneur général Paul Doumer définissait les bases d’un projet d’exposition internationale pour l’année 1902. Et pour s’assurer d’un important traitement médiatique, les organisateurs initiaient la création d’un comité de la presse métropolitaine appelé à rejoindre les représentants de la presse coloniale locale - alors florissante - mais aussi de la presse internationale. À travers la redécouverte de cette exposition internationale, bien oubliée de nos jours, il s’agira pour nous d’analyser les relations tissées entre le monde de la presse et la machine coloniale alors à l’œuvre dans ce territoire colonial. Pour ce faire, notre article vise à explorer tant la « petite » que la « grande » histoire de ce comité : les réseaux métropolitains sollicités par les autorités coloniales, sa composition, les conditions matérielles mobilisées et enfin, les retombées médiatiques relevées.
La compagnie des volontaires de la Martinique dans l’expédition du Mexique (1862-1864)
Authors: Murez Jean-Baptiste
Published: April 2024

Face aux maladies tropicales décimant le corps expéditionnaire français au Mexique, le commandement militaire ressent le besoin d’utiliser des troupes résistantes à ces affections et aux fortes chaleurs. Parmi celles-ci, une compagnie de volontaires recrutés à la Martinique, territoire colonial non soumis à la conscription. L’appel n’attire que peu de candidats, car ces troupes sont traitées différemment des autres unités françaises, malgré certaines mises en garde. Leur solde est moindre, leurs missions sont ingrates : garder les points principaux des terres chaudes littorales, surveiller les convois. Encadrés par des officiers des troupes de marine, ces volontaires s’acquittent toutefois bien de leur tâche, et leurs services sont appréciés. Pourtant, malgré une prise de conscience tardive, leurs conditions évoluent peu et, faute de volonté de se rengager, comme de nouveaux volontaires, la compagnie est dissoute après deux ans d’existence (1862-1864).
Les débats sur la départementalisation à La Réunion : logiques d’intégration et d’adaptation au contexte indiaocéanique (1945-1947)
Authors: Boulaire Marie , Fageol Pierre-Éric
Published: April 2024

La loi du 19 mars 1946 est perçue comme l’aboutissement d’un processus assimilationniste amorcé depuis longtemps au sein des vieilles colonies de l’empire français. Au niveau national, les débats parlementaires montrent que la loi a été incarnée par un petit groupe de députés ultramarins qui ont pu faire corps en partageant des logiques et des enjeux communs en dépit de leur ancrage politique différent. À La Réunion, les lenteurs et les difficultés d’application de la loi ont suscité de vives réactions au sein de la presse réunionnaise plutôt favorable à la départementalisation, même si des voix s’élèvent pour rappeler certaines urgences et l’état sanitaire déplorable de l’île. Bien que le sentiment d’appartenance nationale ne soit pas remis en cause, les logiques résultant de la départementalisation expliquent à elles seules l’échec de l’intégration de cette ancienne colonie à son aire géographique naturelle au sud-ouest de l’océan Indien.
Principes fondamentaux et axes stratégiques de la politique de protection des sols et des sous-sols en France
Authors: Bailly Guillaume
Published: April 2024

L’action de l’État en matière de protection des sols et des sous-sols s’est articulée autour de trois principes généraux indissociables : la prévention et remédiation des pollutions, l’étude au cas par cas de la situation de chaque site prenant en compte les vecteurs et les cibles d’exposition, et l’évaluation du risque fondée sur les usages du site. Dernièrement, la loi climat et résilience a consacré ces principes en introduisant dans le code de l’environnement un nouveau chapitre unique dédié aux « Principes généraux de la protection des sols et des sous-sols ».
Révision de la directive IED
Authors: Perrin Jean-Luc , Malgorn Loïc
Published: April 2024

Depuis 1996, la réglementation européenne encadre la conception et le fonctionnement des installations industrielles les plus émettrices de polluants, dans le but de promouvoir la mise en œuvre des meilleures techniques disponibles afin de réduire, à la source et de façon intégrée par rapport à tous les milieux, les émissions. L’application des meilleures techniques disponibles s’appuie sur le processus dit « de Séville » d’élaboration des documents « BREF ». Ce processus consiste à recueillir les données existantes d’émission des industries concernées et fonder les obligations techniques sur des données réelles quant à la disponibilité et l’efficacité des techniques. La révision en cours de la directive renforce les obligations de rapportage des États membres, les informations à publier pour le public, permet des dérogations supplémentaires pour les technologies innovantes et durcit les conditions de délivrance des permis. Les possibilités d’indemnisations des particuliers sont étendues.
Quel contrôle de la pollution industrielle en Chine ?
Authors: Boudet Julien
Published: April 2024

L’exceptionnel développement économique et industriel de la Chine s’est fait au détriment de son environnement. Néanmoins, une prise de conscience amorcée dans les années 2010 a mené à un renforcement rapide des politiques publiques environnementales. Au cœur de l’économie chinoise avec près de 28 % de son PIB, le secteur manufacturier est naturellement concerné au premier plan par ces nouvelles mesures. C’est particulièrement le cas pour le secteur des industries lourdes, source majeure de polluants atmosphériques et de gaz à effet de serre. En Chine, le contrôle de la pollution se fonde sur l’étude d’impact environnemental et le permis de rejets de polluants. Ce dernier est le principal outil de surveillance des pollutions industrielles. La réglementation met en place des mesures différenciées suivant les industries et les zones d’émissions. Le succès de cet outil encore en construction dépendra des moyens humains, techniques et politiques mis en place.
L’usage métaphorique du bouclier. Autour du scutum fidei dans l’imaginaire médiéval
Authors: Girbea Catalina
Published: April 2024

Si les épîtres de saint Paul, et particulièrement l’Epître aux Ephésiens, ont consacré au Moyen Âge l’image de la foi comme un bouclier, l’idée est bien plus ancienne et elle plonge ses racines dans l’Ancien Testament, qui ménage au bouclier de Dieu une place de choix. Cet usage métaphorique d’un objet qui appartient normalement à l’équipement militaire s’installe au cœur de l’imaginaire médiéval, qu’il s’agisse de romans, de récits didactiques et allégoriques ou tout simplement de chroniques. Le bouclier de Dieu ou de la foi se retrouve également dans l’iconographie des manuscrits contenant des textes théologiques, décrivant des représentations allégoriques complexes qui mettent en scène des psychomachies.
L’écu et l’épée dans Artus de Bretagne
Authors: Ferlampin-Acher Christine
Published: April 2024

Dans Artus de Bretagne , dont la première partie a été composée vers 1300, le héros porte un écu blanc ou échiqueté. L’article revient sur cette alternance ainsi que sur la paire constituée par l’écu et l’épée, deux éléments qui permettent de soutenir l’hypothèse d’une écriture en deux temps, la fin du roman étant une continuation allographe. Le motif du don des fées permet quant à lui d’éclairer la pratique intertextuelle à l’œuvre dans ce récit néo-arthurien. Malgré le caractère formulaire d’un certain nombre de mentions coordonnées, l’épée et l’écu ne constituent pas véritablement une paire : l’écu, dans la première partie du roman, vole la vedette à l’épée, pourtant distinguée par le nom de Clarence. Plus que l’épée, l’écu est associé à la lumière et à l’amour ; il trouve sa place dans les tableaux qui exaltent la cour et la chevalerie et en esthétisent les représentations, et contribue à construire Artus comme héros restaurateur de lumière ; de plus l’écu médiatise et met en image le corps à corps amoureux. Cependant le traitement de l’épée et de l’écu n’est pas uniforme tout au long du texte, la fin à partir du § 419 étant vraisemblablement une continuation allographe, qui a ajouté – maladroitement – l’échiqueté breton, et qui, plus épique que courtoise, rétablit la primauté de l’épée et rétrograde l’écu.
Les armoriaux arthuriens au xvi e siècle en France et Angleterre. Origine et développement des armoriaux arthuriens imprimés
Authors: Ilina Alexandra
Published: April 2024

Cette étude porte sur les transformations subies par les armoriaux arthuriens à l’époque du livre imprimé et s’intéresse aux fonctions de ces paratextes au xvi e  siècle. Les deux premiers armoriaux concernés sont ceux de François Regnault et de Benoît Rigaud, inspirés principalement par la liste publiée par le célèbre Antoine Vérard au début de son Guiron le Courtois de 1501. À la fin du xvi e  siècle, la Devise est traduite et adaptée en anglais par Richard Robinson. L’ancien armorial français est intégré dans les spectacles arthuriens organisés dans le milieu urbain anglais, où les identités des chevaliers arthuriens deviennent des rôles assumés par les membres les plus riches de la bourgeoisie londonienne. À travers les trois exemples investigués, l’armorial arthurien se décline comme une source prestigieuse pour l’imaginaire néo-chevaleresque.
Evaluating the environmental impact on connected vehicles during freeway accidents using VISSIM with probe vehicle data
Authors: Shin Hyunju , Ko Jieun , Lee Gunwoo , Oh Cheol
Published: April 2024

We evaluated emissions as an environmental effect resulting from connected vehicles (CVs) during freeway accidents. The CVs were used to determine the CV driving characteristics, whose values were used to implement the CV driving pattern using a microscopic traffic simulation. The environmental effect of implementation of CV was evaluated using the vehicle trajectory data derived from the simulation results. Implementation of CV effectively minimized the vehicle emissions regardless of the market penetration rate (MPR). In terms of vehicle type, the emissions reduction rate of passenger cars was the highest at a maximum of 33.4%. In the case of pollutants, the reduction rate of CO based on all vehicles was the highest at a maximum of 28.8%. Overall, we found that the implementation of CV positively affected vehicle emissions reductions, and an MPR of 60% could maximize the vehicle emissions reduction effect.
Architects’ houses in the Brussels-Capital Region (1830-1970)
Authors: Van de Voorde Stephanie , Raaffels Linsy , Van der Wee Barbara , Bertels Inge
Published: April 2024

Les maisons d’architecte constituent une catégorie de logements à part, qui revêtent une signification particulière en tant que « carte de visite » de l’architecte, projet expérimental, aboutissement ou synthèse de l’ensemble de son œuvre, englobant des caractéristiques stylistiques, géographiques, techniques, sociales et autres. Toutefois, afin de saisir pleinement l’importance et la valeur ajoutée de ce genre architectural, il est essentiel de disposer d’un cadre théorique et typologique bien défini pour comprendre les maisons d’architecte. Sur la base des données recueillies à partir d’inventaires et de documents existants, de recherches dans les archives et de visites sur le terrain, un vaste registre dans lequel sont recensées 370 maisons d’architecte de la Région de Bruxelles-Capitale a été établi, qui constitue le point de départ de l’analyse. Ce registre se concentre sur la période de 1830 à 1970, au cours de laquelle la construction de maisons d’architecte et de logements en général s’est intensifiée. Il comprend des maisons d’architecte emblématiques et célèbres, ainsi que des exemples moins connus, dans des proportions à peu près égales : nombre de ces édifices n’étaient pas répertoriés auparavant et peuvent désormais être qualifiés à juste titre de maisons d’architecte. Témoignant de la diversité de ces maisons, le registre constitue la base indispensable pour apprécier de manière approfondie les différents cas, ainsi que la maison d’architecte en tant que type de bâtiment particulier.
Calculation of Equal Resistance Riveted Joint
Authors: Charkasov Shahin
Published: April 2024

Rivet joints are used in structures that can withstand large vibration and repeated loads, as well as for connecting parts made of non-weldable materials and not allowing welding due toheating parts. In addition, riveted connections widely used to connect seversl parts in one package. In instrument making, rivet connections are used more often than in mechanical engineering. Among all constructions applied in the technique, constructions with equal resistance are considered optimal. Thus, equal stresses are created in any element of these constructions and even at any point of each element. When the value of these stresses is equal to the allowable stress, the mass of the structure is minimal. With a theoretically correct choice of the optimal elements of the connection, its destruction should occur along all of the above sections simultaneously. Riveted connections must be of equal strength. This means that the calculation must ensure the strength of the rivets against shear and crushing, the walls of the holes for the rivets-against crushing, thr parts connected along weakened sections-against tension, and their edges-against shear (puncture). The issue of design of riveted joint with equal resistance is considered. A formula has been obtained that indicates that the diameter of the rivet depends on the thickness, width and number of rivets of the connected parts (sheets).

Effect of Addition of Sn on High-Temperature Tensile Strength of Rare-Earth Free Mg-1Ca Alloy
Authors: Rashed H.M. Mamun Al , Mim Shad Inquiad , Mallick Bijoy
Published: April 2024

Magnesium alloys have spurred a strong interest in automobile and aerospace industries owing to their high specific strength and stiffness, with magnesium being the lightest structural metal. Alloying with rare earth improves tensile properties considerably. However, the availability of rare-earth elements is a concern. Therefore, attempts are being made to prepare alloys without rare-earth elements. One Mg-1Ca alloy was prepared with different amounts of Sn to study the impact on the high-temperature strength after dynamic recrystallization by hot rolling. Optical and electron microscopy analyzed the change in the microstructure. XRD and EDS were used to identify phases and composition of different microconstituent particles and high-temperature strength was measured at 250°C, 300°C, and 350 °C under 2 x 10-4 s -1 strain rate and at 3000C, 3500C, 4000C, and 4500C temperature under 5 x 10 -4 s -1 strain rate. According to XRD investigation, the alloys essentially comprise the Ca-containing phase and Mg2Sn particles. The Mg-1Ca-1Sn alloy exhibited maximum high-temperature strength at 250°C, attributed to the maximum amounts of MgCaSn particles. It was also found that dynamic recrystallization was accelerated by particle-stimulated nucleation and maximum refinement was found at 1% Sn-containing alloys.
Dynamic Mechanical Analysis of Graphene Oxide/ Low Density Polyethylene Nanocomposite
Authors: Neena Prasad
Published: April 2024

The global scientific community for the last three decades focuses mainly on polymer-based nanocomposites due to their ease of fabrication, flexibility, and above all easiness to handle them. Among the polymer materials, polyethylene got the attraction because of its readiness to be combined with most of the filler materials available in natural form as well as newly synthesized ones. The present study focuses on the synthesis of nanocomposites of Low-density polyethylene (LDPE) with graphene oxide nanoparticles as the filler. The graphene oxide nanoparticles are synthesized using a modified Hummers method. The composites are prepared by varying the amount of graphene oxide nanoparticles in the LDPE matrix using the melt extrusion method. The nanocomposites prepared were found to have good mechanical properties compared to the virgin LDPE material. The Dynamic Mechanic Analysis (DMA) confirmed that the quantity of the graphene oxide nanoparticles has a major role in the viscoelastic behaviour of the composites.

Published: April 2024

Objectives: Bicipital tendinopathy causes shoulder pain and reduced range of motion (ROM). Analgesics and physiotherapy are used as treatments. The objective is to study the effectiveness of myofascial release for bicipital tendinopathy.Methods: Sixty patients with anterior shoulder pain were randomly allocated to control and experimental groups (n=30/group). Control group received conventional physiotherapy for 10 days, while experimental group received myofascial release. Pain scores and ROM of the shoulder were assessed using a visual analog scale and digital inclinometer respectively, on days 1, 5 and 10. On each day, measurements were obtained before and after intervention.Results: Control group consisted of 8 females and 22 males with a mean age of 35.1± 15.2 years. Interventional group consisted of 9 females and 21 males with a mean age of 34.4± 12.3 years. Rest pain for control group on day 1, day 5 and day 10 (pre and post intervention) were 6.7±0.29,6.03±0.29, 5.63±0.29, 5.17±0.24, 4.90±0.26, 4.43±0.27, respectively. Same parameters for the experimental group were 6.60±0.35, 5.00±0.39, 4.30±0.30, 3.60±0.26, 3.10±0.26, 2.56±0.25, respectively. Both interventions significantly reduced pain scores compared to the baseline. Notably, experimental group demonstrated a greater reduction in pain score from day 1 to day 10 compared to the control group (p<0.0001). In the control group, change in ROM from the baseline for each session was 2.960±0.97, 3.660±1.22, 4.560±1.27, 4.430±1.07, and 5.200±1.17. In the experimental group, the corresponding values were 15.100±5.37, 16.430±5.51, 20.870±6.66, 22.670±7.41, and 23.330±7.71. The experimental group showed significantly greater improvement in ROM compared to the control group at each session (p<0.001).Conclusions: Myofascial release works better than conventional physiotherapy for bicipital tendinopathy as it results in greater improvement of pain and ROM. Further research warrants to explore what could be the exact mechanism by which those improvements were happened.

Authors: Turner Jeffrey A. , Hartshorne Matthew , Cameron Kenneth L. , Padua Darin
Published: April 2024

Context

Lower extremity joint (LE) kinematics during landing tasks are important predictors of injury risk and performance outcomes in athletes.

Objective

To establish sex-related differences and normative ranges for LE kinematics during the jump-landing task in a large cohort of healthy military service academy cadets.

Design

Cross-Sectional Study.

Setting

US Air Force, Naval, and Military Academies.

Participants

5308 cadets (2062 females [38.8%]).

Main Outcome Measure(s)

Sex-related differences in LE kinematics were analyzed using independent samples t-tests. Mean differences (MD) and effect sizes (d) were reported for interpretability. Normative ranges for hip and knee joint angles were established separately for males and females at initial contact (IC) and 50% of the stance phase.

Results

Compared to males, moderate effect sizes (d ≥ .5) were observed for knee external rotation (negative value) where females displayed greater motion at IC and at 50% stance (MD: - 3.9˚ and -5.0˚, respectively, p < .001). The following findings were of small effect size (.2 ≥ d > .5). Females exhibited less knee and hip flexion at IC (MD: -1.8˚ and -0.5˚, respectively, p < .001) and at 50% stance (MD: -4.1˚ and -4.6˚, respectfully, p < .001). This was accompanied by females having greater knee valgus (negative value) and hip adduction at IC (MD: -2.2˚ and 1.06˚, respectively, p < .001) and at 50% stance (MD: -3.2˚ and 1.8˚, respectfully, p < .001).

Conclusion

This study establishes normative ranges for LE kinematics during the jump-landing task in a large cohort of healthy military service academy cadets entering their first year. Sex- related differences in LE kinematics were observed, highlighting the importance of considering sex as a factor in the evaluation of lower extremity movement quality and management of injury risk.
Health-seeking Behavior among Mothers of Under-five Children in Sokoto Metropolis, Sokoto, Nigeria
Authors: Adamu Asma’u , Ango Umar Mohammad
Published: April 2024

Background:

In most developing countries, the health of the children is strongly dependent on maternal health-care-seeking behavior. The ability of caregivers to recognize and seek appropriate care for childhood illnesses is instrumental in reducing childhood deaths and preventing significant number of complications. The study aimed to determine the health-care-seeking behavior and associated factors among the mothers of under-five (U5) children in Sokoto Metropolis.

Methodology:

This was a descriptive, cross-sectional study carried out among 386 mothers of U5 children in Sokoto metropolis from August 1 to September 30, 2021. The study participants were selected using the multistage sampling technique. A structured questionnaire was used to collect the information. Data were analyzed using the SPSS version 24. The level of significance for Chi-square was set at a P < 0.05.

Results:

Majority 312 (80.8%) of the respondents U5 children had fallen sick in the last 6 months, most of which 238 (61.7%) were not taken to a health facility. The major reasons why respondents do not take their U5 children to a health facility when sick are because they bought drugs from patent medicine vendor and perceiving the illness of the U5 as not serious to warrant taking the child to a health facility in 93 (24.1%) and 63 (16.3%), respectively. There was association (P ≤ 0.05) between health-care-seeking behavior and respondents’ level of education, occupation, monthly income, as well as distance taken to reach a health facility within 30 min’ walk.

Conclusions:

The health-seeking behavior of the mothers for their U5 was poor. Maternal level of education, occupation, income, and lesser number of children in the family were the factors that were significantly associated with seeking health facility care for a sick U5. This study recommends girl child education, women empowerment, and increase access to family planning by the government.

Over the past twenty years, participatory digital platforms have emerged where observations of more-than-humans are shared. Such citizen science initiatives are considered important for science and policy. This research article draws on affect theory to bring to the fore the affective side of encounters between humans and more-than-humans that comes with this practice. Based on ethnographic fieldwork with Dutch observers, we analyse how observers experience the mediation of the digital observation platform Waarneming.nl, specifically in the context of environmental loss. Based on observations of and conversations with observers, we found that bodily and sensory attentiveness of observers is important in establishing encounters with more-than-humans whilst mediated by Waarneming.nl. We propose that sharing an observation on such platforms is an affective act in itself. Observers show deep care about the more-than-humans they encounter, expressing love as well as worry over their decline. The (not) sharing of these encounters is a way for them to care for more-than-humans. We end this analysis by calling for further reflection on the contrast between the data points on the platform and the affective experiences in the field.

Langerhans cell histiocytosis (LCH), previously known as histiocytosis X, is an idiopathic uncommon haematological condition affecting infants and young children but can occur at any age group characterized by clonal proliferation of abnormal Langerhans cells. Langerhans cells express an immunophenotype positive for S100 protein, CD1a and Langerin (CD207). Here we present a case of 2-year-old male patient presented with a multiple raw area associated with oozing, bleeding and crusted lesions were present over scalp, trunk and post-auricular areas. Radiographic examination revealed multiple osteolytic bone involvement. Histopathological examination revealed Langerhans cell histiocytosis. Immunophenotyping was positive for vimentin, CD1a, and S100. Based on radiological, histological and immunophenotyping findings suggestive of multisystem LCH. The purpose of this report is to describe a rare case of LCH in the 2-year-old male child with multisystem LCH involving skin, soft tissue and bones and to discuss clinical, radiological and histopathological features of LCH.

Skin cancer accounts for most malignancies across the globe. They are primarily divided into melanoma and nonmelanoma skin malignancies. Nonmelanoma skin cancer includes basal cell carcinoma and squamous cell carcinoma. Glycyrrhetinic acid (GA) is a bioactive compound extracted from licorice that exhibits an inhibition effect on various cancers. GA has been reported to have in vitro cytotoxic effects on several human cancer cells. However, reports on the mode of action and detailed mechanism of GA in vitro in skin cancer disease are limited. Hence, GA’s effect on the human skin cell line BJ and MCC13 was investigated. MTT assay showed that GA had cytotoxic effects on MCC13 cells but was non-toxic to the normal cells of BJ in a time-dose dependent manner. GA also inhibited the angiogenic sprouting of new blood vessels in tumor progression. In gene expression assay, GA induces mitochondrial apoptosis through the induction and inhibition of Cytochrome C and Bcl2 respectively. In conclusion, GA is a potent candidate to induce apoptosis and concurrently inhibit the invasion, migration, and angiogenesis of the MCC13 cell line through increasing TNF-alpha concentration resulting in the necroptotic pathway induction.

Authors: Hanafy Samy , Mostafa Taymour , Abd-Elhameed Heba , Rashed Laila , Akl Essam M.
Published: April 2024

Background

Varicocele is considered a common and correctable cause of male infertility. This is established by the improvement of sperm parameters after surgical correction. Endoglin (Eng) is presented in two forms, a membrane and soluble forms, and the equilibrium between these forms depends on the oxidative status. Eng is linked to several pathological conditions common in varicocele as hypoxia and apoptosis.

Aim

This study aimed to evaluate the seminal level of soluble Eng in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocele.

Methods

Sixty men were enrolled in this study. They were divided into two groups: infertile OAT men with varicocele and healthy fertile men as a control group. These participants were subjected to complete history taking, clinical and genital examination, semen analysis, and assessment of soluble Eng pre- and 6 months after the surgical intervention.

Results

The results showed a significant elevation of seminal soluble Eng in infertile OAT men associated with varicocele than in fertile control. Six months postsurgical correction, there was a significant improvement in semen parameters accompanied by a significant decrease in the seminal level of soluble Eng.

Conclusions

It was concluded that seminal soluble Eng is elevated in infertile OAT men linked to varicocele concurrent with the negative effect on sperm parameters. The surgical correction of varicocele in these cases shows significant improvement in these criteria.

Mutations in the hydroxymethylbilane synthase (HMBS) gene can lead to a deficiency of the HMBS enzyme, allowing porphyrins to accumulate to toxic levels in the liver and other organs, leading to acute intermittent porphyria (AIP). This case report describes the medical journey of a 20-year-old female, previously in good health, who experienced multiple hospitalizations and clinic visits due to severe abdominal pain episodes and remained undiagnosed for over 6 years. Despite the nonspecific nature of these symptoms, a suspicion of acute porphyria confirmed by genetic analysis revealed a splice pathogenic variant (c.826-2A>T) in the HMBS gene in a heterozygous state. As the disease progressed, the patient developed a series of complications, including hyponatremia, autonomic instability, and motor neuropathy, culminating in complete paralysis (quadriplegia) and respiratory failure. The case highlights the importance of early recognition and differential diagnoses in managing AIP, with genetic testing playing a crucial role in confirming the diagnosis.

Published: April 2024

Background & objectives:

Dengue poses a considerable public health threat in Saudi Arabia, with escalating outbreaks in Jazan, where seasonal rains create ideal mosquito breeding conditions. Elucidating local epidemiological dynamics is imperative to strengthen evidence-based prevention policies. This study analyzed the spatiotemporal, demographic, and meteorological patterns of dengue in Jazan from 2015-2020.

Methods:

This retrospective cross-sectional study utilized surveillance records for 3427 confirmed dengue cases. Descriptive analyses characterized geographic, seasonal, age, gender, and nationality distributions. Forecasting models project expected epidemics through 2025. Regression analysis identified climate factors associated with monthly case counts.

Results:

Dengue exhibited shifting seasonal peaks, transitioning into year-round transmission by 2019, indicating endemic establishment. Cases clustered in different high-burden sectors annually, requiring localized vector control. The majority of affected individuals were young male adults, with gender gaps narrowing over time. Saudi nationals had an escalating incidence, but non-citizens showed a higher risk, signaling importation threats. Seasonal outbreaks were associated with temperature, wind speed, and direction.

Interpretation & conclusion:

Enhanced surveillance, outbreak forecasting, targeted control activities, and integrated prevention policies grounded in continuous evidence assessment can effectively address endemic dengue transmission in Jazan. This study provides key insights to optimize data-driven decision-making for dengue control in Saudi Arabia.
