Authors: Aldaz Caicedo Priscilla Andreina , Utreras Figueroa Bryan Jason , Flores Droira Sebastian Rene , Castillo Córdoba Lisseth Viviana 
Published: June 2024

La amaurosis fugaz se refiere a la pérdida temporal de la capacidad de ver de forma repentina en un solo ojo, debido a una obstrucción momentánea del flujo de sangre hacia la retina, pudiendo extenderse desde unos cuantos segundos hasta varios minutos. Normalmente, esta condición actúa como un indicador de la presencia de otros problemas de salud. A continuación, vamos a detallar las razones comunes por las que ocurre y las estrategias recomendadas para abordar este problema. La amaurosis fugaz no constituye una enfermedad independiente, sino que puede presentarse como un resultado derivado de la presencia de otros desórdenes médicos. Esto suele ocurrir en los casos en que hay una obstrucción en la arteria. Este fenómeno se produce cuando un coágulo sanguíneo, que es sangre que ha coagulado, o un fragmento de placa formado por la acumulación de sustancias como el colesterol en las arterias, se origina a partir de una arteria de mayor tamaño. La pérdida repentina e inesperada de la capacidad de ver en uno de los ojos es la forma en que se caracteriza el síntoma más importante en este caso. Puede ocurrir durante un breve período de tiempo, que puede ser breve, es decir, de varios segundos a incluso unos pocos minutos, tras lo cual la visión se restablece a su estado normal. Los individuos que han experimentado esto relatan que perciben una presencia de color gris o negro que se desplaza hacia abajo a través de sus ojos. Se reporta un paciente masculino de 60 años de edad, acude por presentar perdida de la visión repentina por varios segundos.

The “Magnificent Seven” X-Ray Isolated Neutron Stars Revisited. I. Improved Timing Solutions and Pulse Profile Analysis
Authors: Bogdanov Slavko , Ho Wynn C. G. 
Published: June 2024

Abstract
We present the first systematic X-ray pulse timing analysis of the six members of the so-called “Magnificent Seven” nearby thermally emitting isolated neutron stars (XINS) with detected pulsations. Using the extensive collection of archival XMM-Newton, Chandra, and NICER observations spanning over two decades, we obtain the first firm measurement of the spin-down rate for RX J2143.0+0654, while for the rest we improve upon previously published spin ephemerides and extend them by up to an additional decade. Five of the XINS follow steady spin-down with no indication of major anomalies in their long-term timing behavior; the notable exception is RX J0720.4−3125, for which, in addition to confirming the previously identified glitch, we detect a second spin derivative. The high-quality folded X-ray pulse profiles produced with the updated timing solutions exhibit diverse and complex morphologies, as well as striking energy dependence. These peculiarities cannot be readily explained by blackbody-like isotropic emission and simple hot-spot configurations, hinting at the presence of complex multitemperature surface heat distributions and highly anisotropic radiation patterns, such as may arise from a strongly magnetized atmospheric layer.
On Calculating Diffusion Coefficients Numerically in Synthetic Turbulence Using Particle Pushers
Authors: Els P. L. , Engelbrecht N. E. 
Published: June 2024

Abstract
Numerical simulations of test particle transport in the presence of synthetic turbulence with known properties still provide the most reliable estimations of the diffusion coefficients of charged particles in turbulent space plasmas available. The development and implementation of such simulations, however, are far from straightforward. The present study provides a comprehensive treatment of the development and testing of such a simulation code, detailing the simulation of synthetic turbulence and diffusion coefficients, as well as various numerical tests to validate code output. Furthermore, a novel test for such codes is proposed, namely, the transport of charged particles in pure slab turbulence, which proves sensitive to numerical factors prior tests remain insensitive to.
Relativistic Brueckner–Hartree–Fock Calculations for Cold and Hot Neutron Stars
Authors: Farrell Delaney , Weber Fridolin 
Published: June 2024

Abstract
This study investigates the properties of symmetric and asymmetric nuclear matter using the relativistic Brueckner–Hartree–Fock formalism, examining both zero and finite temperatures up to 70 MeV. Employing the full Dirac space, we incorporate three Bonn potentials (A, B, and C), which account for meson masses, coupling strengths, cutoff parameters, and form factors. The calculated properties of asymmetric nuclear matter form the basis for constructing equation-of-state (EOS) models tailored for neutron stars. These models, in turn, enable the computation of bulk properties for nonrotating, uniformly rotating, and differentially rotating neutron stars. Notably, the EOS models studied in this paper are sufficiently versatile to accommodate the mass of the most massive neutron star ever detected, PSR J0952–0607, estimated to be 2.35 ± 0.17 M
⊙. Furthermore, they yield masses and radii for PSR J0030+451 that align with the confidence intervals established for this pulsar.
Oblique Compressible Waves in the Reconnection Exhaust Region Embedded in the Inner Heliospheric Current Sheet Observed by Parker Solar Probe
Authors: Zhuo Rui , He Jiansen , Duan Die , Zhu Xingyu , Hou Chuanpeng 
Published: June 2024

Abstract
Magnetic reconnection is an important physical process of energy conversion in the heliosphere. Parker Solar Probe (PSP) passes through current sheets of the inner heliosphere and is likely to encounter magnetic reconnection events there. PSP traversed a magnetic reconnection exhaust region that occurred in the coronal streamer during its perihelion Encounter 8. We report an observation of the counterstream of strahl electrons and compressible waves in the exhaust region on the antisunward side of the reconnection site. We analyze the wave characteristics using electromagnetic singular value decomposition techniques and find that the propagation direction of the compressible waves is quasi-perpendicular to the local magnetic field. Combining with the topology of the magnetic field, we infer that the compressible waves converge from the edge to the center of the exhaust region, and then propagate away from it. Further, we select 12 magnetic reconnection events during Encounter 5–8 for statistics and find that the oblique compressible waves are commonly detected throughout the inner heliospheric current sheet. In addition, we discuss the possible nature of wave branches for these compressible waves. Our work shows that magnetic reconnection in the heliosphere not only changes the topology of the large-scale magnetic field in the heliosphere, but also affects the transport characteristics of solar wind plasma and suprathermal particles, and regulates the states of waves and turbulence in the heliosphere.
Low-frequency Absorption and Radio Recombination Line Features of the Galactic Center Lobe
Authors: Hurley-Walker Natasha , Anderson L. D. , Luisi M. , McClure-Griffiths N. M. , Benjamin Robert A. , Kuhn Michael A. , Linville Dylan J. , Liu B. , Zucker Catherine 
Published: June 2024

Abstract
The Galactic center lobe (GCL) is a ∼1° object located north of the Galactic center. In the mid-infrared, the GCL appears as two 8.0 μm filaments that roughly define an ellipse. There is strong 24 μm and radio continuum emission in the interior of the ellipse. Due to its morphology and location in the sky, previous authors have argued that the GCL is created by outflows from star formation in the central molecular zone or by activity of the central black hole Sgr A*. We present images of the GCL from the GaLactic and Extragalactic All-sky Murchison Widefield Array survey in radio continuum that show thermal absorption against the Galactic center, incompatible with an interpretation of synchrotron self-absorption. Estimates of the cosmic-ray emissivity in this direction allow us to place a distance constraint on the GCL. To be consistent with standard emissivity assumptions, the GCL would be located 2 kpc away. At a distance of 8 kpc, the synchrotron background emissivity is enhanced by ∼75% in the direction of the GCL. We also present radio recombination line data from the Green Bank Telescope that constrain the electron temperature and line widths in this region, which are also more explicable if the GCL lies relatively close.
La parole ‘hors-plateau’ comme source : Réflexion sur l’usage d’une retranscription de table-ronde dans le cadre d’une recherche sur le théâtre au Rwanda
Authors: Le Lay Maëline 
Published: June 2024

Arrimé à la retranscription d’une table-ronde sur « Théâtre, mémoire et réparation au Rwanda » co-animée par l’auteure au Kenya (IFRA-Nairobi) en février 2019, cet article propose une réflexion sur l’usage d’un tel document pour la recherche sur le théâtre et les arts de la scène au Rwanda depuis le génocide. La table-ronde réunissait Carole Karemera, metteuse en scène et directrice de Ishyo Arts Center à Kigali ; Assumpta Mugiraneza, psychologue sociale et politologue, co-fondatrice et directrice de Iriba, centre pour le patrimoine multimédia à Kigali et Ariane Zaytzeff, docteure en études théâtrales, auteure d’une thèse sur le théâtre au Rwanda après le génocide et ex-coordinatrice de la compagnie de danse Amizero basée à Kigali et du festival East African Nights of Tolerance. Tant l’analyse des spectacles des principales femmes de théâtre du Rwanda (Carole Karemera, Hope Azeda, Odile Gakire Katese) que celle d’autres spectacles sur le génocide mettent en exergue l’importance des récits et témoignages sur le génocide portés à la scène. Ces formes semblent être les plus à mêmes de dire la nécessité de porter une parole juste dans une société où la prise de parole n’est pas toujours aisée et tend même à laisser place à un silence polymorphe (à plusieurs facettes et recouvrant des motifs variés). Il s’agit en effet pour les artistes de réinventer une langue et un langage scénique spécifiques qui ne se confondent pas avec les langages du « Nouveau Rwanda » forgés par le gouvernement occupé à reconstruire le pays depuis 1994. Ressortent aussi de la conversation entre les trois intervenantes tenue pendant la table-ronde les questionnements éthiques soulevés par les choix scénographiques et les orientations esthétiques des différent·e·s metteur·e·s en scène, qu’ils viennent d’Europe et du Rwanda. Ce dernier aspect nous conduit à interroger ce qui est représentable sur scène et pour quel(s) public(s), tant les besoins mais aussi les attentes et surtout les limites (éthiques, psychologiques) ne convergent pas nécessairement en fonction qu’on est un spectateur européen en Europe ou un spectateur rwandais. L’article se conclut sur l’opportunité de travailler à partir de matériaux spécifiques comme cette transcription d’une parole publique (puisque déroulée lors d’une table-ronde), et non comme on le fait coutumièrement dans la recherche en sciences humaines et sociales, à partir d’entretiens individuels. Non seulement ce type d’échange peut venir opportunément pallier une difficulté d’accès aux principales informatrices dans le cas d’un terrain délicat comme le Rwanda, mais surtout sa dimension publique et son devenir matérialisé par l’écrit peuvent en faire une source utile tant pour des chercheurs en études théâtrales (africaines, rwandaises) que pour des chercheurs travaillant sur le Rwanda, et plus particulièrement le génocide et ses suites.
« Toute histoire a ses deux versions » : traduire et raconter l’histoire américaine dans Le Dernier des Mohicans de James Fenimore Cooper et ses traductions françaises
Authors: Pilote Pauline 
Published: June 2024

Cet article s’intéresse au Dernier des Mohicans, roman historique américain de James Fenimore Cooper (1826) et à deux de ses traductions en français : celle, contemporaine, par Defauconpret en 1826 et sa retraduction par François Happe en 2017. Plus précisément, l’article se penche sur le discours historique proposé par Cooper et sur le rôle joué par les traducteurs dans la transmission de celui-ci. Proposant une réflexion sur l’écriture de l’Histoire, cet article s’attache à montrer comment les traductions et retraductions en français permettent de faire ressortir les enjeux historiographiques du roman, tels qu’ils sont inscrits par Cooper dans la trame du roman historique, et tels qu’ils sont adaptés au contexte de production de chacune des traductions.
Voyager par la langue : fonctions et autotraductions du pérégrinisme français en fiction et non-fiction anglophone
Authors: Brisset Frédérique 
Published: June 2024

La problématique fiction/non-fiction pose la question de la mimesis. Une forme ou l’autre renverrait-elle plus au « monde-objet » barthésien et par quel biais scriptural ? On compare l’usage de pérégrinismes français dans deux ouvrages, l’un américain, l’autre britannique, de genres littéraires distincts : le premier est un texte pragmatique, précis de conseils diététiques, l’autre une fiction littéraire policière. Signés d’auteur·es bilingues anglais-français, ils s’affichent comme variations transatlantiques du récit de voyage et proposent un nombre inusité de pérégrinismes. Le signalement typographique par l’italique met ces segments hétéroglossiques en relief comme signes de renforcement, exemplificateurs de la véracité du dit diététique dans un « réel » stéréotypique pour le premier ouvrage ; dans le second, ils sont autant de points d’ancrage linguistiques du monde diégétique dans le monde physique extra-diégétique, géographique, sociologique et culturel.En s’appuyant sur la théorie des mondes possibles développée par la logique modale et la sémiotique, ainsi que sur les études lexicologiques, traductologiques, narratologiques, cette étude de cas explore comment et à quelles fins les auteurs du corpus usent de ces ressources verbales allophones, comment, enfin, celles-ci servent la mimesis pour dépasser l’opposition entre fiction et non-fiction. Il s’agit aussi de cibler les stratégies discursives et traductives qui permettent à ce lexique d’être appréhendé à sa réception par le lectorat monolingue originel sans perdre l’effet de « réel » voulu par les écrivain·es.
Le “Parangon de Nouvelles” (1531). Vérité et civilité entre France et Italie
Authors: Cavallini Concetta 
Published: June 2024

The Parangon de Nouvelles (1531), a collection of stories from different sources (Boccace, Pogge, Valla but also the popular German anthology Til Eulenspiegel) allows to consider the analysis of the «franc parler» as a social phenomenon. The parresia can be considered as a narrative strategy but also as an element identifying characters or groups of characters; it can also be considered as a true actant in the narration.
Sustained Alleviation of Autoimmunity by Activating α2B-adrenergic Receptors
Authors: Viswanath Veena , Mistry Shruti , Cabrera-Ghayouri Sara , Leang Ronika , Frail Don , Donello John , Gil Daniel 
Published: June 2024

Abstract
Catecholamines binding to α- and β-adrenergic receptors on immune cells have recently been shown to play an important role in regulating immune responses. Although α2-adrenergic receptors are known to modulate the immune response in different ways, the therapeutic exploration of their utility has been limited by the lack of agonists selective for the three α2-adrenergic subtypes. We report in this study the identification of the agonist AGN-762, which activates α2B- and α2C-adrenergic subtypes, but not the α2A subtype. We show that AGN-762 reduced clinical disease in an experimental autoimmune encephalitis model of autoimmune disease via direct or indirect effects on T regulatory cells. The activity of AGN-762 was abrogated by depletion of T regulatory cells, which express the α2B-adrenergic receptor. Furthermore, a drug-induced shift to an anti-inflammatory phenotype was demonstrated in immune cells in the spleen of drug-treated experimental autoimmune encephalitis mice. AGN-762 does not display sedative and cardiovascular side effects associated with α2A subtype agonists. Immune modulation by selective α2-adrenergic agonists represents a novel, to our knowledge, approach for treating autoimmune disease.
Transcription Factor Activity Regulating Macrophage Heterogeneity during Skin Wound Healing

Published: June 2024

Abstract
Monocytes and macrophages (Mos/Mϕs) play diverse roles in wound healing by adopting a spectrum of functional phenotypes; however, the regulation of such heterogeneity remains poorly defined. We enhanced our previously published Bayesian inference TF activity model, incorporating both single-cell RNA sequencing and single-cell ATAC sequencing data to infer transcription factor (TF) activity in Mos/Mϕs during skin wound healing. We found that wound Mos/Mϕs clustered into early-stage Mos/Mϕs, late-stage Mϕs, and APCs, and that each cluster showed differential chromatin accessibility and differential predicted TF activity that did not always correlate with mRNA or protein expression. Network analysis revealed two highly connected large communities involving a total of 19 TFs, highlighting TF cooperation in regulating wound Mos/Mϕs. This analysis also revealed a small community populated by NR4A1 and NFKB1, supporting a proinflammatory link between these TFs. Importantly, we validated a proinflammatory role for NR4A1 activity during wound healing, showing that Nr4a1 knockout mice exhibit decreased inflammatory gene expression in early-stage wound Mos/Mϕs, along with delayed wound re-epithelialization and impaired granulation tissue formation. In summary, our study provides insight into TF activity that regulates Mo/Mϕ heterogeneity during wound healing and provides a rational basis for targeting Mo/Mϕ TF networks to alter phenotypes and improve healing.
Analgesic and anti-inflammatory activity of Cotinus coggygria Scop. extracts in vivo
Authors: Lu Kai , Yang Chong-Yu , Yan Zhao-Hong 
Published: June 2024

Objective:
To assess the analgesic and anti-inflammatory effects of standardized extract of Cotinus coggygria (C. coggygria) in different animal models.

Methods:

C. coggygria extracts (25, 50, and 100 mg/kg) were administered to rats and mice (n=6) during hot plate, tail-flick, acetic acid-induced writhing, and formalin tests to determine its analgesic efficacy. The anti-inflammatory activity of C. coggygria extracts was evaluated by histamine and carrageenan-induced paw edema, cotton pellet-induced granuloma, and acetic acid-induced peritoneal capillary dye leakage tests.

Results:

C. coggygria extracts (50 and 100 mg/kg) significantly alleviated thermal and chemical-induced pain in rodents (P<0.05). It also demonstrated notable anti-inflammatory properties by mitigating histamine and carrageenan-induced paw edema, granuloma deposits, and vascular permeability (P<0.05). Moreover, C. coggygria extracts remarkably reduced TNF-α, IL-1β, IL-6, COX-2, and oxidative stress in rat paws (P<0.05). Carrageenan-induced histological aberrations in hind paw tissues were effectively (P<0.05) mitigated by treatment with C. coggygria extracts.

Conclusions:

C. coggygria Scop. extracts show analgesic and anti-inflammatory effects via inhibition of COX-2 and inflammatory and oxidative mediators.
