Evaluación del efecto del secado con combustión directa de GLP sobre la composición química del grano de café
Authors: Quintero-Yepes Laura
Published: February 2025

El secado mecánico del café es utilizado en fincas cafeteras que no cuentan con el área suficiente para realizar el secado solar o cuando las condiciones climáticas no son las apropiadas para el mismo. Cuando en el proceso de secado mecánico se utilizan combustibles sólidos se emplea un intercambiador de calor, el cual es necesario para lograr una transferencia de calor limpia. Cuando se emplea Gas Licuado de Petróleo (GLP) generalmente, con el fin de reducir los costos, los secadores que utilizan este combustible se instalan sin intercambiador de calor, asumiendo que la combustión del GLP es limpia. No obstante, se desconoce si los gases de combustión generados en el proceso contaminan el grano de café con compuestos tóxicos para la salud humana o afectan su calidad en taza. En el seminario se presentarán los resultados de la evaluación del efecto del secado con combustión directa del GLP sobre la calidad en taza y la composición química del grano, con el fin de determinar la presencia compuestos tóxicos para la salud humana.

Pedestrian Safety in South Africa: A Comprehensive Analysis
Authors: Modipa Mmakwena
Published: February 2025

Pedestrian safety remains a critical concern for road traffic authorities globally, including in South Africa, where pedestrian fatalities are alarmingly high. Numerous factors contribute to the elevated rate of pedestrian deaths in the country. One of the significant issues in South Africa is the lack of prioritization of pedestrian safety. The study analysed pedestrian safety in South Africa and identified factors contributing to pedestrian fatalities and measures to counteract them. This qualitative article utilized a non-empirical research design through a systematic review, relying entirely on secondary data. The systematic review thoroughly examined the collected literature. Key findings revealed that road users often disregard traffic rules, increasing their risk of involvement in road accidents, and are frequently distracted while on the road. Additionally, the study found that road traffic authorities do not adequately focus on pedestrian safety, and resource shortages further hinder their ability to respond effectively to road user safety. Based on these findings, several recommendations were made: it is advised that road users should be engaged in road safety campaigns to enhance their understanding of the importance of following traffic regulations. Moreover, it is recommended that road traffic authorities should be provided with sufficient resources to tackle the issue of pedestrian fatalities. Lastly, it is suggested that road traffic authorities should establish partnerships to address pedestrian safety. The study will assist policymakers, road safety strategists, road traffic authorities, the
Department of Transport, and its agencies in dealing with pedestrian fatalities.

Strategies to Improve School-Based Support Towards Access and Success of Rural Learners
Authors: Netshipale Adziliwi Martha , Tlale Lloyd Daniel Nkoli , Phala Thembi AL
Published: February 2025

Rural schools are susceptible to various challenges due to their geographical locations, which places them far from the resources and amenities necessary for teaching and learning. This creates barriers that impede access to and success in education. To address these, schools require specific interventions or approaches that target contextual challenges and rely on the availability and functionality of support systems. This paper aimed to outline the school-based support strategy that can be used to reinforce support initiatives at the school level to promote access to and improve success in education. The paper emanates from a study that adopted a qualitative approach, interpretivism paradigm and instrumental case study design. Data was collected through questionnaires, field notes, focus groups and individual interviews with 35 participants in five rural schools in Gauteng North district, South Africa. The findings revealed that three out of five schools did not have functional school-based support teams in place and conducted unstructured and disorganised support services in silos. Non-functionality of support teams was attributed to time constraints, misalignment of policies with rural contexts, inadequate educational resources and inadequacies of teachers’ skills and capabilities. The study recommends reinforcement of support services through a school-based support strategy with five pillars of support. The findings contribute to existing discussions around school-based support in education and its role in educational achievement and accessibility of learning opportunities. Findings also pave the way for further studies that employ different methodologies to expand the existing knowledge.

Published: February 2025

When it comes to local economies, micro, small, and medium-sized enterprises (MSMEs) play a crucial role in creating jobs and generating tax money. Financial management and decision-making are two areas that management accounting information systems mostly seek to improve. This research aims to fill a gap in our understanding of what drives small and medium-sized enterprises (SMEs) in the Garut Region to use MAS. The Garut Cooperative Office-registered SMEs in the Garut Region were the primary subjects of this research. Researchers used a purposive sampling strategy to choose research participants. For this investigation, thirty samples were taken from MSMEs that had been in operation for more than two years. Researchers used traditional assumption testing and multiple linear regression to examine the data. While the research did find that accounting informing system usage was affected by education level, after adjusting for firm age and size, no influence was observed on management accounting informing system use. Micro, small, and medium-sized enterprises (MSMEs) are more likely to use a management accounting information system if employees have higher levels of education, the business is larger, and the organization is older. These linkages are illuminated by this research.
Hooks, Lines, and Sinkers: How Active Galactic Nucleus Feedback and Cosmic-Ray Transport Shape the Far-infrared–Radio Correlation of Galaxies

The far-infrared–radio correlation (FRC) is one of the most promising empirical constraints on the role of cosmic rays (CRs) and magnetic fields in galaxy formation and evolution. While many theories have been proposed in order to explain the emergence and maintenance of the FRC across a gamut of galaxy properties and redshift, the nonlinear physics at play remain unexplored in full complexity and within a cosmological context. We present the first reproduction of the z ∼ 0 FRC using detailed synthetic observations of state-of-the-art cosmological zoom-in simulations from the Feedback in Realistic Environments (FIRE-3) suite with explicitly evolved CR proton and electron (CRe) spectra, for three models for CR transport and multichannel active galactic nucleus (AGN) feedback. In doing so, we generally verify the predictions of “calorimeter” theories at high FIR luminosities (L
60 μm ≳ 109.5
L
⊙) and at low FIR luminosities (L
60 μm ≲ 109.5
L
⊙), the so-called “conspiracy” of increasing UV radiation escape in tandem with increasing CRe escape, and find that the global FRC is insensitive to orders-of-magnitude locally variable CR transport coefficients. Importantly, the indirect effect of AGN feedback on emergent observables highlights novel interpretations of outliers in the FRC. In particular, we find that in many cases “radio-excess” objects can be better understood as “IR-dim” objects with longer-lived radio contributions at low z from Type Ia supernovae and intermittent black hole accretion in quenching galaxies, though this is sensitive to the interplay of CR transport and AGN feedback physics. This creates characteristic evolutionary tracks leading to the z = 0 FRC, which shape the subsequent late-time behavior of each model.

Published: February 2025

We present an observational study of the S284-RE region, a low-metallicity area associated with the extended S284 H ii region. A thermally supercritical filament (mass ∼2402 M
⊙ and length ∼8.5 pc) is investigated using the Herschel column density map. The Spitzer ratio 4.5 μm/3.6 μm map traces the H2 outflows in this filament, where previously reported young stellar objects (YSOs) are spatially distributed. Analysis of the YSO distribution has revealed three active star-forming clusters (YCl1, YCl2, and YCl3) within the filament. YCl3 seems to be the most evolved and YCl2 the youngest, while YCl1 displays signs of nonthermal fragmentation. The JWST (F470N+F444W)/F356W ratio map reveals at least seven bipolar H2 outflows, with four (olc1–olc4) in YCl1 and three (ol1–ol3) in YCl2. The driving sources of these outflows are identified based on outflow geometry, Atacama Large Millimeter/submillimeter Array (ALMA) continuum peaks, and YSO positions. Two ALMA continuum sources—#2 and #3—from the M–R
eff plot are recognized as potential massive star formation candidates. ALMA continuum source #2 hosts at least three outflow-driving sources, whereas ALMA continuum source #3 contains two. The bipolar outflow olc1, driven by an embedded object within continuum source #2, is likely a massive protostar, as indicated by the Br-α and PAH emissions depicted in the JWST (F405N+F444W)/F356W ratio map. The presence of H2 knots in the outflows olc1 and ol1 suggests episodic accretion. Overall, the study investigates a massive protostar candidate, driving the ∼2.7 pc H2 outflow olc1 and undergoing episodic accretion.

Published: February 2025

Radio-quiet Seyfert galaxies have been detected in GeV gamma rays by the Fermi Large Area Telescope (LAT), but the origin of much of this emission is unclear. We consider the nearby example GRS 1734−292, which exhibits weak starburst and jet activities that are insufficient to explain the observed gamma-ray flux. With the first detailed multiwavelength study of this source, we demonstrate that an active galactic nucleus (AGN) disk wind can account for its gamma-ray emission. Using a lepto-hadronic emission model based on a shocked ambient medium and a shocked wind region created by an AGN accretion disk wind, we identify two viable scenarios that are consistent with the Fermi-LAT data and multiwavelength observations: a hadronic pp-dominated scenario and a leptonic external-Compton-dominated scenario. Both of these show that future observations with the Cherenkov Telescope Array and the Southern Wide-field Gamma-ray Observatory could detect TeV emission from a disk wind in GRS 1734−292. Such a detection would substantially improve our understanding of cosmic-ray acceleration efficiency in AGN disk wind systems and would establish radio-quiet Seyfert galaxies as cosmic-ray accelerators capable of reaching ultrahigh energies.
Analytical and Numerical Methods for Circumbinary Disk Dynamics. II. Inclined Disks
Authors: Pirog Michal , Mahesh Siddharth , McWilliams Sean T.
Published: February 2025

To gain insight into the dynamical influence of a supermassive black hole binary on a circumbinary accretion disk, we investigate the binary and viscous torque densities throughout such a disk, with emphasis on the final density distribution, particularly the size and stability of the central gap between the binary and the inner edge of the disk. We limit ourselves to the simplified case of a massless viscous thin accretion disk under the influence of the gravitational potential from a binary system whose orbital plane is inclined relative to the disk. We employ two-dimensional Newtonian hydrodynamics simulations to examine the influence of two model parameters: the mass ratio of the binary and the inclination angle between the binary and the disk. We investigate their impact on the density and torque distribution. In our analytical approach, we consider the stability of epicycles induced by the perturbative effect of the asymmetric inclined binary gravitational potential on Keplerian circular orbits. Through our simulations, we observe that certain configurations never attain a quasi-steady state, where the density profile averaged over many orbits stabilizes. This instability occurs when the inclination is close to 45°. Furthermore, we identify configurations where there is never a persistent balance between the dynamical and viscous torque densities, as well as cases where the location of this balance oscillates or exhibits other time-dependent behavior over viscous timescales. These findings have implications for understanding both the expected gravitational-wave signal and electromagnetic counterparts from supermassive black hole binaries.
Predicting Solar Energetic Particle Events with Time Series Shapelets

Published: February 2025

Solar energetic particle (SEP) events pose significant risks to both space and ground-level infrastructure, as well as to human health in space. Understanding and predicting these events are critical for mitigating their potential impacts. In this paper, we address the challenge of predicting SEP events using proton flux data. We leverage some of the most recent advances in time series data mining, such as shapelets and the matrix profile, to propose a simple and easily understandable prediction approach. Our objective is to mitigate the interpretability challenges inherent to most machine learning models and to show that other methods exist that can not only yield accurate forecasts but also facilitate exploration and insight generation within the data domain. For this purpose, we construct a multivariate time series data set consisting of proton flux data recorded by the National Oceanic and Atmospheric Administration's geosynchronous orbit Earth-observing satellite. Then, we use our proposed approach to mine shapelets and make predictions using a random forest classifier. We demonstrate that our approach rivals state-of-the-art SEP prediction, offering superior interpretability and the ability to predict SEP events before their parent eruptive flares.
Shaping Outflows and Jets by Ambient Pressure: A Unified Framework
Authors: Baan Willem A. , An Tao
Published: February 2025

Astrophysical outflows are ubiquitous across cosmic scales, from stellar to galactic systems. While diverse launching mechanisms have been proposed, we demonstrate that these outflows share a fundamental commonality: their morphology follows the physics of pressure-confined supersonic flows. By extending classical de Laval nozzle theory to account for ambient pressure gradients, we present a unified framework that successfully describes outflows from young stellar objects to active galactic nuclei. This simplified approach, compared to full magnetohydrodynamic treatments, captures the essential physics governing outflow shapes across different scales. Our model reveals a remarkable consistency of pressure profiles, characterized by a power-law exponent near “–2” across 6 orders of magnitude in spatial scale, independent of the internal characteristics of the outflow or the nature of the central engine. This discovery suggests a universal mechanism for outflow collimation and acceleration, bridging the gap between theoretical models and observational features across a wide range of astronomical scales.
Intrinsic Pulse Widths of FRB 20121102A and Calculation of Broadening from Propagation and Instrumental Effects
Authors: Wei Jia-Peng , Huang Yong-Feng , Cui Lang , Liu Xiang , Geng Jin-Jun , Wu Xue-Feng
Published: February 2025

The pulse widths of fast radio bursts are always broadened due to the scattering of the plasma medium through which the electromagnetic wave passes. The recorded pulse width will be further affected by the radio telescopes since the sampling time and the bandwidth cannot be infinitely small. In this study, we focus on the pulse widths of at least 3287 bursts detected from FRB 20121102A as of 2023 October. Various effects such as the scattering broadening, the redshift-induced broadening, and the instrumental broadening are examined. At a redshift of 0.193, the pulse width is broadened by a factor of approximately 0.16 due to cosmological time dilation. It is found that the instrumental broadening only contributes a fraction of 10−3–10−1 to the observed pulse width. The scattering broadening is even smaller, which constitutes a tiny fraction of 10−5–10−2 in the observed pulse width. After correcting for these broadenings, the intrinsic pulse width is derived for each burst. The maximum and minimum pulse widths at different frequencies are highlighted. The intrinsic widths of most bursts are in a narrow range of 1–10 ms, which leads to a quasi-linear correlation between the fluence and the peak flux. Additionally, the mean value and the dispersion range of intrinsic pulse width are found to scale with the central frequency as ν
−1.2±0.2 and ν
−1.7±0.6, respectively.
Testing the Flux Rope Paradigm for Coronal Mass Ejections Using a Three-spacecraft Encounter Event

7 east of Earth. The reconstruction assumes a magnetic flux rope (MFR) structure for the CME. With this event, we test whether field tracings observed by a spacecraft passing near the central axis of a CME MFR (STEREO-A) can be used to successfully predict the field behavior seen by a spacecraft 17∘ away (SolO), which has a more grazing encounter with the CME. We find that the MFR model does have significant success in simultaneously reproducing the field signs and rotations seen at STEREO-A, Wind, and SolO. This provides support for the MFR paradigm for CME structure. However, the SolO measurements, which are farthest from the central axis of the MFR, show less defined MFR signatures, presumably due to a greater degree of erosion and degradation of the MFR structure far from its central axis.
Fundamental Understanding of Magnetic Reconnection via Spiral CT Scan. I. Density, Temperature, Pressure, and Method Validation
Authors: Fu H. S. , Wang Z. , Cao J. B.
Published: February 2025

For the first time, we reveal the distribution of plasma density, electron temperature, thermal pressure, and total pressure around a reconnection X-line, by using the spiral CT scan technique, which is a novel technique analogous to that in the hospital. This X-line was detected by the Magnetospheric Multiscale spacecraft and has been widely believed to host a non-guide-field reconnection in previous studies. With the help of such an advanced technique, we find that (1) the plasma density is low on the magnetosphere side but high on the magnetosheath side; (2) the electron temperature is high on the magnetosphere side but low on the magnetosheath side; (3) the thermal pressure is high near the current sheet but low away from the current sheet; (4) the total pressure in the inflow region is higher than near the current sheet. Among these findings, the first three agree with classical theories, hence validating our novel scan technique; the last one implicates that antiparallel magnetic field lines were being pushed together and the reconnection process was ongoing.

The near-Earth asteroid (98943) Torifune, previously designated 2001 CC21, is the flyby target of the Hayabusa2 extended mission, nicknamed Hayabusa2# (Small Hazardous Asteroid Reconnaissance Probe (SHARP)). The ground-based telescope observations offer a key science input for the mission's scientific investigation. During 2022–2024, this asteroid was at visible apparent magnitudes brighter than 18.5, allowing for a detailed characterization using ground-based telescope observations. We determined its rotation period P = 5.021516 ± 0.000106 hr and its absolute magnitude H = 18.78  ±  0.14.

Telomere DNA in the insect order Dermaptera and the first evidence for the non-canonical telomeric motif TTCGG in Arthropoda
Authors: Lukhtanov Vladimir A.
Published: February 2025

Despite recent advances in telomere research, the telomere DNA organization remains unknown for representatives of several insect orders. In this study, analysis of the chromosome-level genome assembly shows that the telomeric DNA of the earwig Labia minor (Linnaeus, 1758) (Polyneoptera, Dermaptera, Spongiphoridae) consists of repeats of the 5 bp motif TTCGG/CCGAA. This is the first record describing the structure of telomeric DNA in the order Dermaptera. This record expands the spectrum of the known telomeric sequences, since the TTCGG motif has not been reported for insects previously.
Micro-CT assessment of sealant penetration in different types of fissures in primary molars
Authors: Hristov Krasimir , Bogovska-Gigova Ralitsa , Georgieva Nedana
Published: February 2025

Introduction: Sealants prevent the development of dental caries by forming a protective barrier that reduces bacterial growth and food retention. The morphology of the pits and fissures and the material of the sealant can affect the depth to which it penetrates into the fissures and the longevity and durability of the sealant.

Aim: To compare the depth of penetration into fissures and pits of different types of sealants in primary molars using micro-CT assessment.

Material and methods: Forty intact primary molars were extracted just prior to their physiologic exfoliation. They were sealed with glass ionomer cement (GIC) and resin sealant. The samples were scanned with a desktop X-ray microtomograph. The fissure profile, sealant penetration depth, and depth of the unfilled part of the fissure were measured. Descriptive and inferential statistics were used to analyze the data.

Results: The median penetration depth of GIC was 89% (IQR 81.31%–100.00%) in U-type fissures and 66% (IQR 55.64%–76.77%) in V-type fissures. The deepest median penetration with resin sealant was found in U-type fissures 89% (IQR 73.16%–100.00%) and the shallowest median depth was found in IK-type fissures 34% (IQR 25.39%–41.73%). Penetration depths ranged from 34% to 43% in the I and IK fissure types. No statistically significant difference was found in the penetration of the two types of sealants in the different types of fissures (p>0.05), except for those classified as other types. There, a significantly greater depth of penetration was found in the group of teeth sealed with GIC - median 56%, compared to the resin sealant, which reached only 40% of the fissure depth (p=0.003).

Conclusion: The morphology of the fissure plays a more important role in determining the depth to which the sealant will penetrate the fissure than the type of sealant material used.

Aquatic ecosystems in riverine wetlands are important refuges and nurseries for freshwater biota. Given the significant global loss and degradation of wetlands, regular conservation assessments of these habitats, even in not easily accessible regions, are crucial for implementing effective management. Thus, developing cost-effective approaches for rapid ecological and conservation screening of water bodies in floodplains, such as the Danube, is a priority. One potential solution is the use of UAV-based (Unmanned Aerial Vehicle) ecological indicators to complement existing monitoring frameworks. This paper aims to explore whether UAV-based macrophyte data can provide a more precise indication of the trophic state and conservation indices (assessed through fish and macroinvertebrate communities) of temperate wetland lentic ecosystems, compared to traditional field surveys. The fieldwork was conducted during the summer months of 2019 at 23 sampling sites within eight lentic water bodies located in three wetland areas along the Middle Danube in Serbia. Data on aquatic vegetation, fish, and macroinvertebrate communities, and samples for water quality analysis were collected simultaneously. UAV images were acquired using an RGB camera. Orthomosaics were processed using supervised object-based image (OBIA) classification to obtain a single vector layer with macrophyte functional groups and taxa. Macrophyte cover metrics obtained during the fieldwork and UAV data processing were correlated against water quality parameters and conservation indices calculated for fish and macroinvertebrate assemblages. The study demonstrated that UAV photogrammetry can provide relatively precise measurements of macrophyte cover characteristics compared to traditional plot-based monitoring methods, making it effective for assessing aquatic ecosystems. The analysis revealed that sites with high values of fish and macroinvertebrate conservation indices, optimal oxygen conditions, and mesotrophic states were associated with UAV orthomosaic polygons showing relatively high macrophyte functional diversity and a presence of floating-rooted species. Conversely, sites experiencing eutrophication and a poor oxygen regime with species-poor fish assemblages correlated positively with a higher cover of amphibian and free-floating vegetation, as well as filamentous algae. In conclusion, UAV photogrammetry offers a cost-effective method to monitor aquatic habitats along large river floodplains, including those that are not easily accessible.

Published: February 2025

Les approches moléculaires de recherche des variants des gènes codant la prothrombine (F2) et la proaccélérine (F5) ont considérablement évolué, depuis leur description et le rapport du Groupe Français d’étude sur l’Hémostase et la Thrombose émis en 2009, en raison de l’apparition de nombreuses trousses diagnostiques. L’objectif de cette revue est de faire l’état des pratiques actuelles des laboratoires spécialisés dans cette analyse. Nous exposerons ainsi les performances analytiques des trousses commerciales disponibles et utilisées en 2019 par la plupart des laboratoires français autorisés.

Published: February 2025

Les lymphomes T sont des pathologies fréquemment investiguées par les seuls pathologistes, le clinicien n’ayant, la plupart du temps, pas accès aux données que pourraient proposer les laboratoires d’hématologie. La connaissance, par les biologistes, des principales caractéristiques de leur classification est importante afin que le dialogue inter-spécialités puisse être fructueux et que la pathologie soit catégorisée le plus précisément possible. L’objet de cet article est de rappeler aux biologistes les principaux caractères cliniques, morphologiques, immunophénotypiques, cytogénétiques et moléculaires de ces pathologies hétérogènes répertoriées par l’Organisation mondiale de la Santé, en rappelant, sur différentes figures, les principaux aspects souvent observables par le cytologiste.
La découverte de la quinine par Joseph Pelletier et Joseph B. Caventou (1820)
Authors: Chast François
Published: February 2025

C’est dans le contexte d’une révolution de la conception des médicaments que Pelletier et Caventou découvrirent la quinine en 1820, à Paris. Cette révolution consistait à ne plus proposer l’approche thérapeutique des maladies au moyen de préparations galéniques complexes de plantes (extraits, teintures, etc.) et de n’utiliser que les substances pures qui pouvaient en être extraites. Pelletier avait déjà isolé l’émétine de l’ipéca, dès 1817 et avec Caventou, il avait extrait la strychnine de la fève de Saint-Ignace en 1819. De son côté, Sertürner, en Allemagne, avait publié sa découverte de la morphine dans l’opium dès 1817. Ce contexte avait incité les deux pharmaciens parisiens à isoler le principe actif des quinquinas, ce qui revêtait une difficulté particulière compte tenu de la diversité des espèces en usage et de la complexité chimique de ces plantes. Leur travail présenté à l’Académie des sciences fut immédiatement reconnu comme fondateur, non seulement en matière de chimie extractive des alcaloïdes, mais aussi pour l’utilisation thérapeutique qui pouvait être faite de la quinine dans le traitement des fièvres en général et du paludisme en particulier. Le fait qu’ils aient renoncé à tout droit sur leur invention n’est pas étranger à leur désignation comme « bienfaiteurs de l’humanité ».
Complications thromboemboliques lors de la première vague de COVID-19 : quels enseignements pratiques pour le biologiste médical ?

Le 31 décembre 2019, l’Organisation mondiale de la Santé (OMS) est informée de l’existence de cas de pneumonies virales d’étiologie inconnue détectés à Wuhan, dans la province du Hubei, en Chine. En quelques semaines, ce nouveau virus dénommé le SARS-CoV-2 ( severe acute respiratory syndrome coronavirus 2 ), responsable de la COVID-19 ( coronavirus disease 2019 ), a conduit à une pandémie d’une ampleur exceptionnelle. Si la maladie est le plus souvent bénigne, elle est responsable chez certains patients d’un syndrome de détresse respiratoire aiguё qui nécessite une prise en charge hospitalière. Ces patients atteints par une forme grave de la maladie développent des événements thromboemboliques veineux avec une fréquence inhabituellement élevée pour une infection virale. Dans cette revue, nous présentons les fréquences des thromboses veineuses profondes et embolies pulmonaires observées lors de la première vague de la pandémie, à partir des études publiées. Nous décrivons également la physiopathologie de la maladie thromboembolique veineuse (MTEV) chez ces patients et les anomalies biologiques associées. Enfin, nous présentons les schémas de thromboprophylaxie et de traitement de la MTEV actuellement proposés par les sociétés savantes, dans l’attente des résultats d’essais randomisés sur cette pathologie.
Rôle central du biologiste dans le diagnostic du syndrome MYH9
Authors: Delecourt-billet M. , Avon Catherine , Binard S. , Fenneteau O. , Hurtaud Marie-Françoise
Published: February 2025

Le syndrome MYH9 est une thrombopénie héréditaire de degré variable, caractérisée par la présence de grandes plaquettes et d’agrégats de myosine intraleucocytaires, révélés par des inclusions basophiles après coloration de May-Grünwald-Giemsa d’un frottis sanguin. Cliniquement, il peut s’accompagner : (a) d’un éventuel syndrome hémorragique corrélé à la profondeur de la thrombopénie, (b) de l’apparition, au cours de la vie, d’une surdité, d’une cataracte précoce et/ou d’une atteinte rénale pouvant évoluer jusqu’à une insuffisance rénale terminale. Dans cet article, nous décrivons les caractéristiques cliniques et biologiques du syndrome MYH9 qui permettent au biologiste médical de jouer un rôle central dans son diagnostic.
Diagnostic des mycoses d’importation
Authors: Jacquet Richard , Bigot Juliette , Hennequin Carole
Published: February 2025

En raison de l’essor des déplacements humains dans le monde, touristiques, professionnels ou migratoires, les biologistes sont parfois confrontés au diagnostic d’une mycose contractée en dehors de la France métropolitaine. Ces mycoses dites « d’importation » prennent principalement l’aspect d’infections invasives opportunistes, souvent à point d’entrée pulmonaire (histoplasmose, talaromycose, coccidioïdomycose), ou de lésions cutanées ou sous-cutanées lentement évolutives (sporotrichose, mycétomes). La connaissance de la distribution géographique et des principaux points d’appel cliniques de ces infections fongiques est essentielle pour les suspecter. Leur diagnostic est établi par l’examen microscopique de produits biologiques ou de tissus et par leur culture, celle-ci devant être réalisée, pour certains champignons, dans des conditions de sécurité optimales compte tenu de leur virulence.
Thrombopénies thrombotiques induites par la vaccination contre la COVID-19
Authors: Vayne C. , Rollin J.
Published: February 2025

Mises en évidence pour la première fois en mars 2021, les thrombopénies thrombotiques induites par un vaccin contre la COVID-19 ( Vaccine-induced thrombotic thrombocytopenia, VITT) sont une complication très rare des vaccins à vecteur adénovirus utilisés dans la lutte contre le SARS-CoV-2, et notamment ChAdOx1 nCoV-19 (Vaxzevria ; Oxford–AstraZeneca). Les VITT sont exceptionnelles (≃ 1 cas pour 100 000 injections), mais très graves (mortalité estimée entre 20 et 50 %), se manifestant par des thromboses multiples et atypiques, en particulier cérébrales et splanchniques, associées à une thrombopénie souvent profonde (< 50 G/L) et une activation massive de l’hémostase, comme en témoignent les concentrations circulantes très élevées de D-dimères. Ces évènements thrombotiques surviennent très majoritairement dans un délai de 5 à 30 jours après une primo-vaccination et semblent principalement dus à l’apparition d’anticorps anti-facteur plaquettaire 4 (FP4) qui activent puissamment les plaquettes. L’état des patients pouvant se détériorer très rapidement, tout tableau clinico-biologique évocateur doit faire rechercher une VITT le plus tôt possible pour permettre une prise en charge thérapeutique adaptée et efficace. Si ce nouveau syndrome est aujourd’hui mieux compris, son diagnostic n’en reste pas moins un challenge, en particulier en raison des performances très variables des outils diagnostiques disponibles, ce qui justifie l’implication impérative d’un laboratoire d’hémostase spécialisée.
Transitional justice and impunity for fascism in southern Europe: The case of Spain in a comparative perspective
Authors: Moreno Fonseret Roque , Payá López Pedro
Published: February 2025

This article addresses four cases of transitional justice practised in southern Europe from 1945 to the present day: France, Italy, Portugal, and Spain, to which special attention is paid. Representatives of what are considered the first and second wave of transitional justice, they have in common the fascist experience but the ways of facing the violent past are dissimilar due to its different national and international contexts. In France and Italy, the criminal justice, administrative purges, and economic sanctions that were applied were preceded by extra-legal repression exercised during the final phase of the war, the liberation, and the immediate postwar period in what was known as an épuration and in which the Resistance played a leading role. On the contrary, in the transitions of the late 1970s, criminal justice was applied minimally in Portugal, where administrative purges prevailed, and was non-existent in Spain, because of the Amnesty Law of 1977. Although impunity accompanied all the processes studied, the comparison reveals the singularity of the Spanish case, with a greater degree of consequence of a transition to a non-disruptive democracy with the Franco dictatorship. In the same way, in all cases, reconciliation with the past has extended into the 21st century and it has also been in Spain where it has presented the greatest difficulties.
Pour une dramaturgie de l’espace,le théâtre d’archiviozeta dans le Cimetière militaire germanique du col de la Futa
Authors: Polvani Simona
Published: February 2025

Bâti entre 1962 et 1965 par l’architecte Dieder Oesterlen, le Cimetière militaire germanique du col de la Futa (Soldatenfriedhof Futa Pass), situé dans les montagnes de l’Apennin toscan-émilien, constitue le plus grand sacraire germanique en Italie. Sa construction évoque l’idée d’une spirale sans fin, qui soudainement s’interrompt, avec ses 2 000 mètres de mur entourant la montagne et les sépulcres qu’elle abrite. Dirigée par le duo d’artistes Gianluca Guidotti et Enrica Sangiovanni (metteurs en scène, dramaturges, comédiens), la compagnie italienne archiviozeta, depuis 2003, investit chaque été ce lieu avec des spectacles créés in situ. Adaptations de textes épiques, de tragédies grecques, des pièces contemporaines ou bien de romans, ce sont des spectacles dont le sujet se veut en résonance critique avec ce lieu tragique. Se déroulant pendant l’après-midi jusqu’au coucher de soleil, ces spectacles itinérants et ambulatoires en plein air n’ont pour scénographie que l’environnement architectural et naturel du cimetière, des montagnes qui l’entourent et du ciel. archiviozeta définit le travail spécifique d’écriture, mise en scène et d’inscription dans ce lieu comme une « dramaturgie de l’espace ». Moyennant l’analyse des choix du répertoire théâtral et des pratiques de la création théâtrale mises en place par archiviozeta face aux contraintes et au potentiel de ce sacraire, cet article se propose de questionner la notion de « dramaturgie de l’espace » et les particularités de ce travail théâtral d’un point de vue esthétique, environnemental, relationnel, autant par rapport à ce geste artistique qu’à l’expérience sensible des spectateurs. Il en émerge un théâtre à la fois politique et environnemental, où la nature, imprévisible, s’impose comme véritable partenaire de jeu.
