Authors: Zhuravlyova L. V. , Pyvovarov O. V.
Published: December 2021

The article reviews the sources of scientific literature on the role of somatomedin - insulin-like growth factor-1 (IGF-1) in predicting the development of metabolic disorders in patients with hypertension, the depth of the search for a period of 10 years. It is noted that this scientific problem has been studied in different countries, the connection between IGF-1 deficiency and the occurrence of metabolic disorders in patients with hypertension (AH) is considered to be one of the predictors of cardiovascular disease. It was experimentally established that the study of the content of IGF-1 in the blood revealed a significant decrease in the level of somatomedin in groups of patients with varying degrees of hypertension. Studies have confirmed the pathogenetic role of IGF-1 deficiency in the development of left ventricular hypertrophy and heart failure in patients with hypertension in combination with type 2 diabetes mellitus (DM). It is the deficiency of IGF-1 in the blood was associated with the development of degenerative processes. Immune-modulating ability of IGF-1 has been established, antithrombotic and antiremodeling properties of somatomedin have been proved. It was found that people with normal blood pressure and people without signs of impaired glucose tolerance had significantly higher levels of IGF-1 in the blood.

It is established that the study of the role of IGF-1 in the prediction of metabolic disorders in patients with hypertension is a promising scientific problem.

On the Impact of Inclination-dependent Attenuation on Derived Star Formation Histories: Results from Disk Galaxies in the Great Observatories Origins Deep Survey Fields

Published: December 2021

We develop and implement an inclination-dependent attenuation prescription for spectral energy distribution (SED) fitting and study its impact on derived star formation histories. We apply our prescription within the SED fitting code Lightning to a clean sample of 82, z = 0.21–1.35 disk-dominated galaxies in the Great Observatories Origins Deep Survey North and South fields. To compare our inclination-dependent attenuation prescription with more traditional fitting prescriptions, we also fit the SEDs with the inclination-independent Calzetti et al. (2000) attenuation curve. From this comparison, we find that fits to a subset of 58, z < 0.7 galaxies in our sample, utilizing the Calzetti et al. (2000) prescription, recover similar trends with inclination as the inclination-dependent fits for the far-UV-band attenuation and recent star formation rates. However, we find a difference between prescriptions in the optical attenuation (A

V
) that is strongly correlated with inclination (p‐value < 10−11). For more face-on galaxies, with i ≲ 50°, (edge-on, i ≈ 90°), the average derived A

V
is 0.31 ± 0.11 magnitudes lower (0.56 ± 0.16 magnitudes higher) for the inclination-dependent model compared to traditional methods. Further, the ratio of stellar masses between prescriptions also has a significant (p‐value < 10−2) trend with inclination. For i = 0°–65°, stellar masses are systematically consistent between fits, with

dex and scatter of 0.11 dex. However, for i ≈ 80°–90°, the derived stellar masses are lower for the Calzetti et al. (2000) fits by an average factor of 0.17 ± 0.03 dex and scatter of 0.13 dex. Therefore, these results suggest that SED fitting assuming the Calzetti et al. (2000) attenuation law potentially underestimates stellar masses in highly inclined disk-dominated galaxies.

GW190814 was a compact object binary coalescence detected in gravitational waves by Advanced LIGO and Advanced Virgo that garnered exceptional community interest due to its excellent localization and the uncertain nature of the binary’s lighter-mass component (either the heaviest known neutron star, or the lightest known black hole). Despite extensive follow-up observations, no electromagnetic counterpart has been identified. Here, we present new radio observations of 75 galaxies within the localization volume at Δt ≈ 35–266 days post-merger. Our observations cover ∼32% of the total stellar luminosity in the final localization volume and extend to later timescales than previously reported searches, allowing us to place the deepest constraints to date on the existence of a radio afterglow from a highly off-axis relativistic jet launched during the merger (assuming that the merger occurred within the observed area). For a viewing angle of ∼46° (the best-fit binary inclination derived from the gravitational wave signal) and assumed electron and magnetic field energy fractions of ϵ

e
= 0.1 and ϵ

B
= 0.01, we can rule out a typical short gamma-ray burst-like Gaussian jet with an opening angle of 15° and isotropic-equivalent kinetic energy 2 × 1051 erg propagating into a constant-density medium n ≳ 0.1 cm−3. These are the first limits resulting from a galaxy-targeted search for a radio counterpart to a gravitational wave event, and we discuss the challenges—and possible advantages—of applying similar search strategies to future events using current and upcoming radio facilities.

We measure the star formation rate (SFR) per unit gas mass and the star formation efficiency (SFEgas for total gas, SFEmol for the molecular gas) in 81 nearby galaxies selected from the EDGE-CALIFA survey, using 12CO (J = 1–0) and optical IFU data. For this analysis we stack CO spectra coherently by using the velocities of Hα detections to detect fainter CO emission out to galactocentric radii r
gal ∼ 1.2r

e) and include the effects of metallicity and high surface densities in the CO-to-H2 conversion. We determine the scale lengths for the molecular and stellar components, finding a close to 1:1 relation between them. This result indicates that CO emission and star formation activity are closely related. We examine the radial dependence of SFEgas on physical parameters such as galactocentric radius, stellar surface density Σ⋆, dynamical equilibrium pressure P
DE, orbital timescale τ
orb, and the Toomre Q stability parameter (including star and gas Q
star+gas). We observe a generally smooth, continuous exponential decline in the SFEgas with r

and a morphological dependence of the SFEgas per orbital time, which may reflect star formation quenching due to the presence of a bulge component. We do not find a clear correlation between SFEgas and Q

The identification of an emission line is unambiguous when multiple spectral features are clearly visible in the same spectrum. However, in many cases, only one line is detected, making it difficult to correctly determine the redshift. We developed a freely available unsupervised machine-learning algorithm based on unbiased topology (UMLAUT) that can be used in a very wide variety of contexts, including the identification of single emission lines. To this purpose, the algorithm combines different sources of information, such as the apparent magnitude, size and color of the emitting source, and the equivalent width and wavelength of the detected line. In each specific case, the algorithm automatically identifies the most relevant ones (i.e., those able to minimize the dispersion associated with the output parameter). The outputs can be easily integrated into different algorithms, allowing us to combine supervised and unsupervised techniques and increasing the overall accuracy. We tested our software on WISP (WFC3 IR Spectroscopic Parallel) survey data. WISP represents one of the closest existing analogs to the near-IR spectroscopic surveys that are going to be performed by the future Euclid and Roman missions. These missions will investigate the large-scale structure of the universe by surveying a large portion of the extragalactic sky in near-IR slitless spectroscopy, detecting a relevant fraction of single emission lines. In our tests, UMLAUT correctly identifies real lines in 83.2% of the cases. The accuracy is slightly higher (84.4%) when combining our unsupervised approach with a supervised approach we previously developed.

An increasing public health problem: Suspected rabies exposures
Authors: Porsuk Ahmet Onder , Cerit Cigdem
Published: December 2021

Introduction: The increasing trend of rabies suspected exposures is a serious public health problem that is challenging the health systems of developing countries both in terms of labor and economics. The purpose of our study is to determine the current state of rabies suspected exposure cases.

Methodology: This descriptive and cross-sectional study was conducted by retrospectively examining the applications made due to suspected exposures to a state hospital’s emergency service in Turkey. Descriptive and analytical statistics were used in data analysis and p ≤ 0.05 was considered as statistically significant.

Results: Between 2015 and 2019, 3,378 hospital admissions due to suspected exposures were detected (n = 3,378). The number of admissions, which was 558 in 2015, increased every year and reached 829 in 2019 (p < 0.001). Also admissions after contact with cats have increased over the years and have passed contact with dogs in 2019 (p < 0.001). Post-exposure prophylaxis was applied to all cases, but 0.8% (n = 26) of them were found to be inappropriate according to guidelines. It was observed that 38.3% of overall cases examined were individuals aged 19 and under. It was also observed that 69.1% (n = 2,326) of the suspected exposures were caused by owned animals (p < 0.001).

Conclusions: The case rates seen in children indicate the need for special studies for children. Applications for suspected exposures due to contact with cats were found to be a growing problem. Therefore, it was concluded that the patterns of rabies suspected exposure cases in Turkey and similar developing countries should be monitored regularly and measures should be taken according to local needs. Besides, stray animals in cities must be minimized and all animals living in cities owned or stray, must be monitored in terms of vaccination.
Consumer’s demand for Disinfectants and Protective Gear from COVID-19 infection in Al-Hofuf, Saudi
Authors: Al-Mahish Mohammed , AlDossari Noura , Almarri Amal
Published: December 2021

Introduction: The paper aims to estimate consumers’ demand for personal protecting products (PPP) from COVID-19. Thus, the paper collected primary data on consumers’ demand for PPP utilizing the timeframe of the COVID-19 pandemic.

Methodology: The paper uses two sample t-test and Anova test to examine mean differences in the quantity consumed of PPP. Also, the paper uses Almost Ideal Demand System (AIDS) to estimate the responsiveness of quantity demanded of PPP for changes in prices and consumers’ income.

Results: The results show that there is a significant difference in the mean of quantity demanded of facemasks among men and women. Also, the results show that there is a significant difference in the mean of quantity demand for facemasks, gloves, and hand sanitizer based on respondents’ level of education. In addition, the paper analyzed the effect of price and income changes on quantity demanded of PPP. The findings indicate that the quantity demanded of facemask and gloves are sensitive to changes in consumers’ income. Also, soap, hand sanitizer, and gloves were recognized as complementary products. Furthermore, facemasks were identified as a complementary product with glove use. Lastly, the own-price elasticities of demand revealed that the demand for PPP is price insensitive.

Conclusions: the paper recommends that the consumer protection unit closely monitor the prices of PPP since the sellers have an opportunity to increase those products prices and maximize their revenue by exploiting the COVID-19 pandemic.

Introduction: Central line-associated bloodstream infections are the second most frequent infection in intensive care units. It represents an adverse event of significant magnitude, thus threatening the patient safety. The aim of this study was to analyze the historical trend of central line-associated bloodstream infections in patients in intensive care units, the rate of infection, central venous catheter utilization ratio, type of pathogen and their antimicrobial resistance pattern.

Methodology: This ecological study was performed at 42 intensive care units from a state capital of the Midwest region of Brazil. Central line-associated bloodstream infections notifications were collected from two databases, the Municipal Coordination for Patient Safety and Infection Control at Healthcare Services, from 2012-2016, and the FormSUS (National Health System Data Processing Company), from 2014-2016.

Results: The incidence of central line-associated bloodstream infections was high and stationary in the period (incidence rate of 2.3 to 3.2 per 1,000 catheter days, central venous catheter utilization ratio average 56,9%). The most frequent microorganisms were coagulase-negative Staphylococcus, Klebsiella pneumoniae, Acinetobacter spp. and Pseudomonas aeruginosa. Resistance to 3rd and 4th generation cephalosporins and carbapenems were detected among Gram-negative bacteria, and resistance to oxacillin among Gram-positive bacteria.

Conclusions: Central line-associated bloodstream infections incidence rates were high, however the historical trend remained stationary in adult intensive care units. Infections were mostly caused by coagulase-negative Staphylococcus, K. pneumoniae, Acinetobacter spp. and Pseudomonas aeruginosa, including multi-drug resistant organisms. These findings point to the need of educational strategies addressing the adherence to established preventive measures and to the rational use of antimicrobials.
Four new species of troglomorphic Coecobrya Yosii, 1956 (Collembola, Entomobryidae) from Thailand based on morphological and molecular evidence, with an updated key of Thai troglomorphic species

Published: December 2021

Four new species of troglomorphic Coecobrya Yosii, 1956 are described from caves located in the central and northeastern regions of Thailand. Coecobrya whittenisp. nov. and C. troglobiasp. nov. are from Khon Kaen province, C. ellisisp. nov. is from Phetchabun province and C. phitsanulokensissp. nov. is from Phitsanulok province. They all exhibit remarkable troglobitic characters i.e. elongated antennae, legs and furca, slender claw complex and large body size. Coecobrya whittenisp. nov. is similar to C. troglobiasp. nov. and they were found a distance of only 3.4 km from each other. However, they are mainly different in the number of An mac on dorsal head and number of chaetae of Th. II. Likewise, C. ellisisp. nov. is similar to C. phitsanulokensissp. nov.. However, they differ in the number of An mac on the dorsal head, the number of central mac on Abd. II, central mac on Abd. IV, lateral mac on Abd. IV and the number of inner teeth of the claw. Moreover, C. ellisisp. nov. has orange pigment dots on the body, a unique character, considering that all other troglomorphic Coecobrya species in Thailand are devoid of pigmentation. The results of the molecular approach based on two partial mitochondrial markers (COI and 16S rDNA) and a nuclear gene fragment (28S rDNA) supported the results of morphological species discrimination in separating the four nominal populations as valid species. An updated dichotomous key of Thai troglomorphic Coecobrya species is also given.
Lectures du De Re Publica en contexte(s), remarques sur la République « impériale »
Authors: Benoist Stéphane
Published: December 2021

À partir d’une sélection de dix-sept extraits du traité de Cicéron De Re Publica , qui permettent d’envisager les modèles politiques grecs, de Platon à Polybe, et leur réception romaine, le contexte particulier de la crise de la République tardive des années 50 avant notre ère, qui a tant affecté la carrière et les réflexions de l’orateur et homme politique, est pris en compte. La mise en perspective des situations de dysfonctionnement des institutions, des années gracquiennes à la décennie 50, offre à Cicéron l’occasion d’une conceptualisation de la chose publique ayant fait l’objet de nombreuses analyses plus ou moins récentes et qu’il est opportun de prolonger désormais dans le temps, des dernières décennies de la République proprement dite aux premiers siècles du Principat, afin d’appréhender au mieux l’État romain.
Une famille d’écrivains, les Mauriac

Published: December 2021

Après le décès soudain et prématuré de leur père, J.-P. Mauriac, à la vocation d’écrivain contrariée, dans la fratrie de ses enfants, puis dans celle des enfants de François Mauriac, se révéleront nombre d’écrivains et cela s’étendra jusqu’à ses arrière-petits-enfants. L’approche de cette famille riche en secrets, dénis et répétitions, avec les alliances inconscientes qui les accompagnent, permet d’appréhender le mystère de cette créativité. Chez les Mauriac, les livres constituent un objet culturel commun qui tisse leurs liens et la pratique de l’écriture est le fait de tous. Chacun en écrivant affirme son identité et manifeste en même temps son appartenance par le recours fréquent à l’autobiographie.
Transformación del paisaje urbano debido a la incorporación de nuevas infraestructuras en la primera mitad del siglo XX en Cuenca (Ecuador)
Authors: Hermida Palacios María Augusta , León González Pablo Armando , Cobo Torres Andrea Daniela
Published: December 2021

En la actualidad, el estudio del paisaje urbano ha adquirido relevancia técnica y científica. Las ciudades cambian y evolucionan constantemente, siendo las infraestructuras uno de los mayores modificadores del paisaje, luego de la agricultura y la urbanización. Durante el siglo XX los sistemas urbanos se ampliaron, se construía una infraestructura centralizada que se extendía conforme crecía la ciudad. El siglo XXI desafía a incorporar infraestructuras distribuidas y nuevas tecnologías como respuesta al cambio climático, que están transformando los paisajes urbanos y sobre los que se debe reflexionar. Para ello, es fundamental aprender del pasado e identificar cómo la incorporación de las infraestructuras y servicios influenciaron en la imagen de la ciudad, transformaron entornos naturales en urbanos y modificaron la forma de vida de sus habitantes. Esta investigación tiene por objetivo identificar los momentos significativos de transformación en el paisaje urbano en la primera mitad del siglo XX en la ciudad de Cuenca (Ecuador), asociados a la incorporación e innovación de infraestructuras y redes de servicios de agua, saneamiento y energía. Se utilizaron fuentes primarias, secundarias y fotografías históricas como herramientas para el análisis de las transformaciones en el paisaje. Los resultados evidencian que los años 20 marcaron un punto de inflexión con el inicio de una renovación modernizadora en el país y específicamente en Cuenca. El auge económico por la explotación de cascarilla y la exportación de sombreros de paja toquilla, se convirtió en motor para la incorporación de infraestructuras. Finalmente, se plantean interrogantes que deberán conducir a una exploración más profunda y a la toma consciente de decisiones frente a este tema en las ciudades.
Declarado en secreto. Matrimonio clandestino y consentimiento paterno en la Barcelona pretridentina
Authors: Fargas Peñarrocha Mariela
Published: December 2021

Sabemos muy poco sobre las experiencias de matrimonio clandestino en la Barcelona de principios de la época moderna. Pero aún sabemos menos acerca del papel que tuvo el consentimiento paterno. Lejos de controlar aquellas uniones, las estimuló. Porque la familia también lo usó como instrumento regulador del sistema de conflicto y consenso en el seno de matrimonios y linajes. En este texto analizamos una microhistoria que muestra un asunto desconocido: cómo la ambigüedad del discurso sobre la participación de padres y de madres en el consentimiento matrimonial de las hijas pudo dar cauce a la clandestinidad.
Entre el rito y la fiesta: la ceremonia bautismal en los siglos XVI-XIX
Authors: González López Tamara
Published: December 2021

La Iglesia trató de controlar todos los pasos de la ceremonia del bautismo a fin de evitar que se cometiesen abusos o se prescindiese de la ortodoxia debida. En este trabajo se pretende realizar una aproximación a la realidad de la administración del bautismo en la diócesis de Lugo, con el objetivo de profundizar en el nivel de respeto de la población y los eclesiásticos a la normativa existente sobre el ritual a seguir. Para ello, nos valemos de la información de partidas bautismales y otros documentos como procesos judiciales y administrativos que son comparados con los manuales y los tratados de la época.
La propiedad agraria de los regulares zamoranos en el siglo XVIII
Authors: Caro López Ceferino
Published: December 2021

Mediante el estudio de los libros de cobro y registros de bienes de los conventos zamoranos se analiza la tipología de la propiedad agraria de los regulares. Las conclusiones principales del estudio son las escasas extensiones de las fincas, su desigual localización en el territorio de la diócesis, las grandes diferencias patrimoniales entre conventos y el peso de los bienes de regulares en las relaciones de explotación de la tierra. El origen de los títulos de propiedad indica que el patrimonio conventual se formó principalmente por actos de compraventa y secundariamente por legados o donaciones. El siglo XVIII fue un período muy favorable para la formación del patrimonio de regulares.
Arte y liturgia en la corte madrileña de los Borbones: rituales nobiliarios en la Casa Ducal de Medinaceli
Authors: Romero Medina Raúl
Published: December 2021

El sacramento del bautismo y la confirmación de un miembro de la Casa Ducal de Medinaceli, primogénito o no, fue durante la Edad Moderna una ocasión importante para mostrarse en sociedad como miembros de una jerarquía aristocrática. Del mismo modo, los rituales en torno a la muerte y su aparato fúnebre. En este contexto, la decoración del palacio y de la parroquia resultaba clave sobre todo por sus ricos muebles y ornamentos textiles. Así, a mediados del siglo XVIII, don Pedro de Alcántara Fernández de Córdoba y Moncada, XII duque de Medinaceli, manda recoger por escrito el protocolo para celebrar los rituales de su Casa. El análisis de este documento inédito centra nuestra atención para reflexionar sobre el arte y el ritual en el contexto de la corte madrileña de los Borbones.
La cuestión teológico-política en la legitimación del franquismo. Premisas conceptuales y evolución histórica
Authors: Carlos Sales Juan
Published: December 2021

Este ensayo de análisis conceptual pretende problematizar algunas de las corrientes teológico-políticas españolas y europeas con el fin de clasificar los procesos del franquismo en relación a la legitimación de su estatuto político. Las intersecciones en el franquismo entre política y religión, más allá de cualquier supuesta vinculación clara y precisa, revisten de una nebulosa problemática precisamente por establecerse como un sistema político pretendidamente influido por la teología católica, desde la que obtiene mayormente su legitimación. Sin una pertinente diferenciación categorial, por tanto, se cae en el riesgo de confundir la naturaleza misma del franquismo y la relación con su etapa histórica. Solo tras este ejercicio de demarcación se podrá avanzar hacia diagnósticos que permitan comprender el complejo cambio de paradigma de las realidades políticas que intervienen a lo largo del Régimen.
Restriction without Quantification: Embedding and Probability for Indicative Conditionals
Authors: Ciardelli Ivano
Published: December 2021

Many modern theories of indicative conditionals treat them as restricted epistemic necessity modals. This view, however, faces two problems. First, indicative conditionals do not behave like necessity modals in embedded contexts, e.g., under ‘might’ and ‘probably’: in these contexts, conditionals do not contribute a universal quantification over epistemic possibilities. Second, when we assess the probability of a conditional, we do not assess how likely it is that the consequent is epistemically necessary given the antecedent. I propose a semantics which solves both problems, while still accounting for the data that motivated the necessity modal view. The account is based on the idea that the semantics of conditionals involves only a restriction of the relevant epistemic state, and no quantification over epistemic possibilities. The relevant quantification is contributed by an attitude parameter in the semantics, which is shifted by epistemic modals. If the conditional is asserted, the designated attitude is acceptance, which contributes a universal quantification, producing the effect of a restricted necessity modal.
Foyers empierrés du Bronze final : nouvelles données anthracologiques issues des structures de combustion du Pré-du-Stand (Grand-Saconnex, Genève, Suisse)
Authors: Henry Auréade , Piguet Martine , Steimer-Herbet Tara , Besse Marie
Published: December 2021

Quatre foyers datés du Bronze final, dont trois à pierres chauffées, ont été découverts récemment lors de l’opération d’archéologie préventive menée sur le site du Pré-du-Stand au Grand-Saconnex (canton de Genève). Leur étude anthracologique avait pour objectif de mieux comprendre les stratégies de sélection du bois en lien avec le fonctionnement de ces structures de combustion. Les résultats parlent en faveur d’une sélection de bois non dégradé issu d’un nombre relativement limité d’essences de la végétation environnante, principalement le chêne, le noisetier et le hêtre. Par ailleurs, l’absence du sapin, généralement bien représenté dans les diagrammes polliniques, et celle des conifères en général, pose question : ces taxons étaient-ils rares localement ou peu prisés comme combustible ? À la lumière des données anthracologiques régionales et supra-régionales, cette étude a permis d’éclairer les comportements de sélection du bois de feu à la fin de l’âge du Bronze, qui semblent témoigner d’une certaine homogénéité. La multiplication des études permettra de confirmer ou, au contraire, d’infirmer les hypothèses formulées grâce à cette première synthèse.
Archéologie des économies insulaires : le cas du complexe archipel des Glénan / île aux Moutons, une approche diachronique et paléoéconomique par l’apport des analyses céramiques
Authors: Gehres Benjamin
Published: December 2021

L’approche paléoéconomique des groupes insulaires de Bretagne nous permet de questionner l’adaptation des modes de vie de ces populations à leur environnement. Il s’agit, à partir d’études pétrographiques et géochimiques des matériaux céramiques, d’identifier l’origine des matériaux utilisés dans la production de poteries, et par-delà de questionner l’organisation de leurs systèmes socio-économiques. Du fait de leurs modes de déplacement, nécessairement réalisés par la mer, ces groupes ont-ils développé des relations sur de plus longues distances que les populations continentales ? Quels sont les modèles de production de céramiques en place sur ces sites ? Les groupes insulaires ont-ils des rayons d’approvisionnements en matières premières plus élevés que les voisins continentaux ? Ces problématiques seront questionnées au travers d’une approche diachronique de quatre sites insulaires localisés dans le complexe formé par l’île aux Moutons et l’archipel des Glénan dans le Finistère, du Néolithique moyen II au second âge du Fer.L’évolution des modes de production de céramiques et de leurs échanges éclaire les interactions entre les îles, et avec le continent. Elle permet d’observer une augmentation des transferts de terres cuites depuis le continent vers les îles, et un changement dans le statut des occupations. Ces analyses démontrent que ces populations ont navigué entre plusieurs îles au sein de « merritoires » préférentiels de collecte de ressources, dont les étendues se révèlent bien supérieures au modèle prédictif développé à partir de populations continentales. Il devient donc nécessaire de repenser nos approches au plus près des environnements des groupes étudiés.
Silver jar from the bosporan sanctuary of Demeter and Kore: results of neutron tomography and XRF investigations
Authors: Zavoikin Alexey , Saprykina Irina , Pelgunova Lubov , Kichanov Sergey , Kozlenko Denis
Published: December 2021

This article presents the results of the study of a halide film formed on a surface of a silver jar found in 2002 in the sanctuary of Demeter and Kore on the Taman Peninsula (Krasnodar region, Russia). Investigated sanctuary is located within Beregovoy 4 settlement and was related to Eleusinian cults, which were already presented on the territory of the Cimmerian Bosporus. This silver jar was placed into a specially prepared ceramic hydriskos tightly closed with a sea herb rope. One side of the jar was covered by a crust of some substance. Firstly it was interpreted as sea salt remains, but in our case, this assumption can be excluded, because this place is located high above the sea level (12.60 m). The sanctuary is located at the foot of a mud volcano (Mount Gorelaya), its last eruption was occurred in 1794. It is known that the chemical composition of Taman volcanic muds is characterized by the presence of both Cl and Br. We assume that the presence of the halide film on the silver jar’s surface can be explained by peloids or volcanic mud, which had been used for medical practices or cultic rituals in the sanctuary of Demeter and Kore.

Il a été découvert en 2019 lors d’une campagne extensive de prospection magnétique, réalisée sur un site d’habitat protohistorique et antique. De nouvelles prospections géophysiques ciblées, combinant méthodes magnétique et électrique, ont été menées dans le cadre d’une thèse intégrée au projet RAPSODIE (Reconnaissance des Agglomérations Protohistoriques du Sud-Ouest : Développement, Imagerie, Environnement). Les résultats obtenus ont permis de documenter davantage ce bâtiment, en livrant son plan et une première vision verticale des vestiges conservés grâce à une section électrique transversale. Il s’agit d’un enclos fossoyé quadrangulaire d’environ 25 m de côté, ouvert à l’est, délimitant un espace interne aménagé d’environ 700 m². En 2020, une fouille archéologique a complété cette approche non destructive en identifiant précisément la source des anomalies magnétiques et électriques. La confrontation des données géophysiques et archéologiques permet ainsi d’appréhender le premier sanctuaire attesté du territoire des Pétrocores, au cœur d’une agglomération ouverte du IIIe s. av. J.-C., un type d’habitat groupé précoce encore mal connu en Europe celtique.

Une fouille préventive menée en 2017 sur une zone humide au « Vau du Guet » à Rivière-les-Fosses en Haute-Marne a été l’occasion de récolter, grâce à l’étude des écofacts conservés (pollen, macrorestes et bois), des données inédites sur le paysage d’un vallon entre le ve et le viie siècle de notre ère. L’impact de l’Homme sur son environnement a pu être observé avec le passage, au cours du haut Moyen Âge, d’un environnement boisé à un espace plus ouvert. Les données archéologiques acquises aux alentours de la mare permettent d’attribuer ces changements à des défrichements liés à l’implantation d’un habitat à proximité.

Suite à une journée thématique « Service et expertise par les sciences archéologiques et de la conservation » organisée par le réseau CAI-RN (Compétences Archéométriques Interdisciplinaires – Réseau National, MITI CNRS) les membres du Comité de Pilotage du réseau CAI-RN ayant participé à cette journée ont souhaité rassembler et clarifier dans ce texte un certain nombre des points évoqués lors des discussions. Ceci en donnant notamment une brève définition des termes « service » et « expertise » et en présentant les différents types de structures liées à la communauté archéométrique et réalisant ces activités. Cette proposition d’une première analyse de la situation actuelle propose aussi quelques pistes de réflexion.
La vie imaginaire d’Albucius selon Pascal Quignard, ou le destin rêvé de l’éloquence
Authors: Tlemsani-Cantin Jawad
Published: December 2021

La vie imaginaire que Pascal Quignard consacre en 1990 à Albucius1, un orateur latin du ier siècle avant Jésus-Christ, a de quoi surprendre, mais elle ouvre paradoxalement bien des pistes pour qui s’intéresse à l’enseignement de l’éloquence à notre époque.Elle met d’abord en scène un représentant de l’éloquence judiciaire en action, un homme qui avait fréquenté les écoles de rhétorique et avait lui‑même eu des disciples. Cette vie, romancée, met aussi en valeur l’importance du désir, du corps, de la gêne même, et surtout de la fable dans un genre qu’on aurait tort de croire exclusivement argumentatif. Enfin, elle montre des orateurs qui, malgré leur exclusion de la vie politique par un empereur liberticide, ont réussi à donner encore plus de force à leurs discours.Dans une approche très contemporaine, Pascal Quignard réfléchit à de nouvelles formes génériques pour la fable et pour le discours, liant étroitement l’une et l’autre afin de voir naître une pensée neuve et de répondre à l’un des besoins fondamentaux de l’homo fabulator.
Temporalidades migratórias na sociedade cubana: interações comunicativas e estruturas morais
Authors: Cristina Salgueiro Marques Ângela , Hernández Elisa
Published: December 2021

Cuba é uma sociedade atravessada por muitas ondas migratórias desde o triunfo da Revolução em 1959 e atualmente está imersa nas recentes transformações da política migratória. Esta análise das conversações online sobre migração no fórum de comentários do site Cubadebate (de 2013 a 2017) visa mostrar como as temporalidades migratórias atravessam a construção coletiva e intersubjetiva de marcos morais avaliativos em torno do sujeito emigrado na atual sociedade cubana. Assim, o texto incentiva a reflexão sobre a ideia de vulnerabilidade associada aos emigrantes em sua sociedade de origem.
Tbet Expression by Regulatory T Cells Is Needed to Protect against Th1-Mediated Immunopathology during Toxoplasma Infection in Mice

Toxoplasma gondii infection has proven to be an ideal model to understand the delicate balance between protective immunity and immune-mediated pathology during infection. Lethal infection causes a collapse of T regulatory cells (Tregs) mediated by the loss of IL-2 and conversion of Tregs to IFN-γ–producing cells. Importantly, these Tregs highly express the Th1 transcription factor Tbet. To determine the role of Tbet in Tregs, we infected Tbx21f/f-Foxp3YFPCre and control Foxp3YFPCre mice with the type II strain of T. gondii, ME49. The majority of Tbx21f/f-Foxp3YFPCre mice succumbed to a nonlethal dose. Notably, parasite burden was reduced in Tbx21f/f-Foxp3YFPCre compared with Foxp3YFPCre control mice. We found that Tbx21f/f-Foxp3YFPCre mice have significantly higher serum levels of proinflammatory cytokines IFN-γ and TNF-α, suggestive of a heightened immune response. To test if CD4+ T cells were driving immunopathology, we treated Tbx21f/f-Foxp3YFPCre mice with anti-CD4–depleting Abs and partially rescued these mice. Broad-spectrum antibiotic treatment also improved survival, demonstrating a role for commensal flora in immunopathology in Tbx21f/f-Foxp3YFPCre mice. RNA sequencing analysis reinforced that Tbet regulates several key cellular pathways, including leukocyte activation, regulation of lymphocyte activation, and cell cycle progression, that help to maintain fitness in Tregs during Th1 responses. Taken together, our data show an important role for Tbet in Tregs in preventing lethal immunopathology during T. gondii infection, further highlighting the protective role of Treg plasticity in controlling immune responses to infection and the microbiota.
ABCB10 Loss Reduces CD4+ T Cell Activation and Memory Formation

Published: December 2021

T cells must shift their metabolism to respond to infections and tumors and to undergo memory formation. The ATP-binding cassette transporter ABCB10 localizes to the mitochondrial inner membrane, where it is thought to export a substrate important in heme biosynthesis and metabolism, but its role in T cell development and activation is unknown. In this article, we use a combination of methods to study the effect of ABCB10 loss in primary and malignantly transformed T cells. Although Abcb10 is dispensable for development of both CD4+ and CD8+ T cells, it is required for expression of specific cytokines in CD4+, but not CD8+, T cells activated in vitro. These defects in cytokine expression are magnified on repeated stimulation. In vivo, CD8+ cells lacking ABCB10 expand more in response to viral infection than their control counterparts, while CD4+ cells show reductions in both number and percentage. CD4+ cells lacking ABCB10 show impairment in Ag-specific memory formation and recall responses that become more severe with time. In malignant human CD4+ Jurkat T cells, we find that CRISPR-mediated ABCB10 disruption recapitulates the same cytokine expression defects upon activation as observed in primary mouse T cells. Mechanistically, ABCB10 deletion in Jurkat T cells disrupts the ability to switch to aerobic glycolysis upon activation. Cumulatively, these results show that ABCB10 is selectively required for specific cytokine responses and memory formation in CD4+ T cells, suggesting that targeting this molecule could be used to mitigate aberrant T cell activation.
Intestinal obstruction due to a broad ligament (Lg latum) hernia

Published: December 2021

Hernias of the broad ligament consist in the protrusion of an intra-abdominal viscus through a defect of the broad ligament. Its cause can be congenital or acquired. They are classified as fenestrated or pouched (Hunt classification) or as their location within the broad ligament (Cilley classification). It is an infrequent cause of internal hernia to be considered in the differential diagnosis of acute intestinal obstructions in women, especially with no surgical history. The high clinical suspicion can help early diagnosis and early treatment, thus avoiding the need for intestinal resection due to ischemia of the herniated intestinal segment. Preoperative diagnosis is difficult due to imaging tests, so laparoscopy can be a useful tool for diagnosis and treatment. We present a clinical case of internal hernia through a defect of the broad ligament, diagnosed and treated by minimally invasive surgery.
Frequency and Correlates of Hypogonadism in Adult Males with Type 2 Diabetes Mellitus
Authors: Gangwar Saurabh K. , Verma Sanjiv K. , Modi Sagar
Published: December 2021

Background and Aims:

There is increasing awareness about an association between type 2 diabetes mellitus (T2DM) and male hypogonadism. However, data are sparse and less uniform with respect to factors associated with hypogonadism in males with T2DM. This study aimed to assess the frequency and correlates of hypogonadism in these subjects.

Materials and Methods:

This cross-sectional study included 130 males with T2DM, age 25-60 years. Study subjects were screened for hypogonadal symptoms using androgen deficiency in aging male (ADAM) questionnaire. Serum total testosterone was measured in subjects with positive ADAM score. Hypogonadism was defined as the presence of positive ADAM score and low serum total testosterone (<3 ng/mL). Clinical and biochemical variables were compared between T2DM subjects with and without hypogonadism.

Results:

Hypogonadism was observed in 26.9% of the study subjects. Hypogonadal symptoms most frequently observed in patients with T2DM and hypogonadism were erectile dysfunction (96.4%), reduced libido (64.3%) and deterioration in work performance (53.6%). Group with T2DM and hypogonadism had higher (i) duration of T2DM (8.9 ± 5.03 vs. 4.8 ± 4.76 years;P= .001), (ii) frequency of diabetic retinopathy (58.3% vs. 27.3%;P= .008), (iii) frequency of diabetic neuropathy (42.9% vs. 19.7%;P= .024), (iv) proportion of subjects on insulin therapy (46.4% vs. 22.4%;P= .027), and (v) HbA1c (10.9 ± 2.63% vs. 9.3 ± 2.42%;P= .006), compared to group without hypogonadism.

Conclusion:

Hypogonadism was present in nearly one-fourth of the study subjects with T2DM. Compared to the subjects without hypogonadism, group with hypogonadism had longer duration of diabetes, higher HbA1c, greater frequencies of diabetic retinopathy and diabetic neuropathy, and more subjects on insulin therapy.
Invariants for metabelian groups of prime power exponent, colorings, and stairs
Authors: Barmak Jonathan Ariel
Published: December 2021

We study the free metabelian group
$M(2,n)$
of prime power exponent n on two generators by means of invariants
$M(2,n)'\to \mathbb {Z}_n$
that we construct from colorings of the squares in the integer grid
$\mathbb {R} \times \mathbb {Z} \cup \mathbb {Z} \times \mathbb {R}$
. In particular, we improve bounds found by Newman for the order of
$M(2,2^k)$
. We study identities in
$M(2,n)$
, which give information about identities in the Burnside group
$B(2,n)$
and the restricted Burnside group
$R(2,n)$
