Bats or rodents, who started it? Short history of the gibbon ape leukaemia virus–koala retrovirus clade. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood
Authors: Mottaghinia Saba , McMichael Lee , Meers Joanne
Published: June 2023

The close genetic relationship between gibbon ape leukaemia virus (GALV) and koala retrovirus (KoRV) has puzzled scientists since its discovery. As the two hosts are separated geographically and taxonomically, it was hypothesized that cross-species transmission of an ancestor virus from another host into gibbons and koalas had occurred. The relatively recent introduction of KoRV into the koala genome and the apparent absence of GALV in wild gibbons suggest that this ancestor virus or a close relative may still be in circulation. Investigation into the nature of this ancestor virus may provide insights on the impact of KoRV on declining koala populations and will also broaden our understanding of host-virus coevolution. A variety of mammalian species have been identified to harbor GALV-like viruses, but the true host of the ancestral virus of KoRV and GALV remains uncertain. Here we provide a short history of the most prominent candidates: rodents and bats.

Published: June 2023

This document represents a synthesis of discussions held online at the Second Koala Retrovirus Workshop in 2021. The three days of discussions were based on workshop presentations and comprise: KoRV foundational science (Day 1); applied management of koalas in zoo populations (Day 2); and applied management of koalas in wild populations (Day 3). Each of these discussions gathers current knowledge, explores points of consensus and disagreement, and identifies important knowledge gaps. Recommendations arise regarding research strategy, interim measures for management, and support of research and management via initiation of working groups on KoRV diagnostics and biobanking.
A dual perspective of organizational resilience (OR) and information technology systems resilience (ITSR): an analysis of interdependencies and tensions
Authors: Gardner LeGars Joanne , Simonin Jacques , Waldeck Roger , Puentes John
Published: June 2023

Contemporary organizations face a rising incidence of disasters, extreme events and crises (Boin and Lodge 2021). In parallel, the socioeconomic landscape is increasingly complex which intensifies inter-organizational dependencies and the risk of cascading failures (Ansell et al. 2021). To survive and perhaps thrive, organizations must cultivate organizational resilience (OR). However, their capacity to do so is currently curtailed. Although it is widely recognized that the performance of organizational processes, functions and capabilities is closely aligned to the effectiveness of associated information technology systems (ITS) (Schultze and Orlikowski 2004); models of OR have yet to elucidate mechanisms by which ITS contribute to resilience capabilities (Annarelli and Nonino 2016). In this conceptual paper, which is a work in progress, we reflect upon the nature of interdependencies and tensions between ITS resilience (ITSR) and OR. We adopt a deductive, qualitative approach to systematically compare OR & ITSR. Our comparative analysis is informed by OR models described by Duchek (2020), Sheffi and Rice Jr (2005) and Weick and Sutcliffe (2011), while for ITSR, we employ the Reactive Manifesto as interpreted by Bonér et al. (2014) and Debski et al. (2017).

Figs 1, 2 illustrate our interpretation of each resilience construct.

As may be seen on Fig. 1 we interpret OR as a three-phase process including preemptive, proactive & recovery phases each possessing associated resilience capabilities. The process may occasion three operational outcomes (or levels of resilience maturity). 1st , 2nd and 3rd order resilience denote organizations that when a disruption occurs,

merely maintain key operations,

rapidly achieve a return to normal operations or

that capitalize on a disruption to achieve an improved post-shock trajectory respectively.

merely maintain key operations,

rapidly achieve a return to normal operations or

that capitalize on a disruption to achieve an improved post-shock trajectory respectively.

ITSR is interpreted via the notion, reactive scalability which describes an organizational system that is both responsive and scalable (Debski et al. 2017) i.e., which is able to rapidly achieve (responsive) appropriately dimensioned (scalable) adaptations to intra and extra-organizational changes.

Our analysis employs a multi-level approach. The preliminary results of the analysis are presented in Table 1.

Upon completion of the analysis, we will elaborate theoretical propositions pertaining to the relationship between the OR and ITSR constructs to guide subsequent empirical research to bridge the theoretical divide between these in reality, indissociable resilience constructs. This comprises the main anticipated contribution.
Comparative analysis of the content of heavy metals in the soils of karst landscapes
Authors: Cholakova Zornitza
Published: June 2023

The essence of karst landscapes is considered. The content of Cu, Zn, Pb, Cr, Ni, Co, Mn, Cd trace elements in the soils of karst landscapes in the Ponor, Vrachanska and Vlahina Mountains, as well as those in The Western and Middle Fore-Balkan (Arbanassi Plateau), Bulgaria, is analyzed using landscape-geochemical, laboratory, mathematical and statistical methods. The obtained results are compared with the average content in the carbonate rocks of Bulgaria (Kuikin et al., 2001), the rendzina (Rendzic Leptosols, LPk, FAO) and the gray forest soils (Haplic Luvisols, LVh, FAO) in the country (according to Atanassov et al., 2002). The importance of the carbonate rock substrate on the concentration of the chemical elements - heavy metals in the studied zonal and azonal soil types was determined.
Modern changes in pellet manufacturing industry in Bosnia and Herzegovina
Authors: Nurković Rahman
Published: June 2023

This paper analyses changes in the modern industrialized pellet manufacturing in Bosnia and Herzegovina, transition of industrial manufacturing, changes in industrial enterprises and changes in industrial branches. Very important changes, closely connected with the introduction of technical- technological innovations and occurrences of new industrial pellet products, have been made in the industrial structure of Bosnia and Herzegovina. Pellet manufacturing from renewable sources of wood energy is ensured for the future as well. Pellet is manufactured from quality dry sawdust, from local resources, our forests, and it is manufactured in Bosnia and Herzegovina. Manufacturing pellet in such way ensures a constant price stability. Under pressure, sawdust turns into bio-fuel which gives of clean and highly efficient thermal energy during burning. Through technological process of pellet manufacturing, raw materials are dried which maximally decreases moisture, and this ensures excellent burning and high energy value. The environmental impact of pellet is minimized because the normal amount of carbon dioxide emitted into the atmosphere is not increased.

Self-restoration of landscapes: theoretical and practical aspects
Authors: Petrova Mariya
Published: June 2023

Field surveying and mapping of anthropogenic landscapes, their analysis, and modelling of the complex processes and structure that are formed in them are all relevant questions in contemporary landscape studies. Numerous territories can be observed in our country where, after reducing or terminating of the anthropogenic activity, landscapes that were impacted to various degrees by human activity start gradually restoring to their previous state, having, however, a modified structure with specific complexity. The present piece of research deals with some theoretical and methodological aspects of the study of the self-restoration of anthropogenic landscapes in Bulgaria.
Тhe current state of immigrant integration policies in the European Union
Authors: Maslarska Ekaterina
Published: June 2023

Last few years the topic of immigrant’s crisis in Europe is one of the top priorities for European union. The scope and the matter of this problem is very important, as it relates to finance, politics and the future of the old continent. The importance of the problem is mainly related to its scale. Previously the European parliament stated that the current migration crisis is the worst since World War II. In 2015 and 2016 alone, more than 2.5 million people applied for asylum in the EU, while more than 2,030 people are thought to have lost their lives in the Mediterranean in the first six months of 2017 alone. The aim of the publication is to make a quick overview of the current state of immigrant’s integration policies in the European Union. The publication includes the newest data regarding the integration of immigrants in EU. Part of it are Eurostat data base from the last few years and the latest survey of Eurobarometer 469 (April 2018). Also, there are presented the latest analysis on the topic, regarding the integration of immigrants. The purpose of this publication is to show the importance of the problem and the policies of the EU which are attempting to solve the issues. The importance of the integration of immigrants will grow in future for sure. Opinions of the EU citizens are shown in the publication and they illustrate that there are still some significant variations in perception of immigrant integration. This would be a big opportunity and a challenge for the EU. The role of the policies of the Union is to improve the approaches of the countries and to help them to create a smooth process of the integration.

Application of machine learning methods for filling and updating nuclear knowledge bases
Authors: Telnov Victor P. , Korovin Yury A.
Published: June 2023

The paper deals with issues of designing and creating knowledge bases in the field of nuclear science and technology. The authors present the results of searching for and testing optimal classification and semantic annotation algorithms applied to the textual network content for the convenience of computer-aided filling and updating of scalable semantic repositories (knowledge bases) in the field of nuclear physics and nuclear power engineering and, in the future, for other subject areas, both in Russian and English. The proposed algorithms will provide a methodological and technological basis for creating problem-oriented knowledge bases as artificial intelligence systems, as well as prerequisites for the development of semantic technologies for acquiring new knowledge on the Internet without direct human participation. Testing of the studied machine learning algorithms is carried out by the cross-validation method using corpora of specialized texts. The novelty of the presented study lies in the application of the Pareto optimality principle for multi-criteria evaluation and ranking of the studied algorithms in the absence of a priori information about the comparative significance of the criteria. The project is implemented in accordance with the Semantic Web standards (RDF, OWL, SPARQL, etc.). There are no technological restrictions for integrating the created knowledge bases with third-party data repositories as well as metasearch, library, reference or information and question-answer systems. The proposed software solutions are based on cloud computing using DBaaS and PaaS service models to ensure the scalability of data warehouses and network services. The created software is in the public domain and can be freely replicated.
Use of remix spent mixed fuel plutonium in the BN-1200 reactor
Authors: Kovalev Nikita V. , Prokoshin Alexander M. , Kudinov Alexander S. , Nevinitsa Vladimir A.
Published: June 2023

The VVER-1000 thermal neutron reactor can operate on mixed uranium-plutonium fuel with a content of reactor-grade plutonium up to 5% with a 100% loaded core. In this case, plutonium burns up to 56% of odd isotopes. The energy potential of such plutonium is very low, and its further use in thermal reactors is impractical. However, such plutonium can be used in fast neutron reactors. The paper presents the results of investigating the possibility for such isotopic plutonium composition to be used in the BN-1200 thermal neutron reactor and its value be increased for the plutonium recycle in the reactor. For this purpose, a precision model of the BN-1200 reactor has been developed using the Serpent Monte Carlo code. The model has been verified against the reference values of the nuclear fuel burnup and breeding ratios. The study has shown that such plutonium can be used in the BN-1200 reactor MOX fuel. Maintaining the operating cycle length requires the plutonium fraction in the MOX fuel to be increased up to 2%. In the BN-1200 reactor, the isotopic composition has been found to improve for the further recycle of plutonium in the thermal reactor, i.e. odd plutonium isotopes increase. The fewer odd plutonium isotopes at the beginning of the BN-1200 operating cycle, the greater their increase. It can be seen as the result of the calculation that plutonium from VVER-1000 spent mixed fuel must be loaded into the BN-1200 reactor at least twice to increase the fraction of odd isotopes to the level of reactor-grade plutonium.
Evaluation of DNBR with neutronics calculation in LWR systems
Authors: Khan Suhail Ahmad , Kannan Umasankari
Published: June 2023

The heat flux in a Light Water Reactor (LWR) system is used to estimate the Departure from Nucleate Boiling Ratio (DNBR) of the system which is an important thermal hydraulic parameter for nuclear reactors from heat removal point of view. The DNBR signifies an operational safety limit i.e. the nuclear power plant has to be operated with sufficient margin from the specified DNBR limit for assuring its safety. The DNBR is evaluated using a thermal hydraulic analysis code using inputs from neutronics calculation. The present paper presents the evaluation approach of minimum DNBR (MDNBR) during standard neutronics calculation. The DNBR calculation is performed using a core physics analysis code and burnup variation of MDNBR is studied for the full cycle length. The results of calculation are presented using the equilibrium core of 2700 MWth/900 MWe Indian Pressurized Water Reactor (IPWR). The calculations are performed using VISWAM-TRIHEXFA code system. The few group lattice parametric library for IPWR is generated by lattice analysis code VISWAM. The core follow up calculation for the equilibrium core configuration has been performed using core analysis code TRIHEXFA. A first order thermal hydraulic feedback model has been introduced into the 3D finite difference core simulation tool TRIHEXFA. The critical heat flux calculation, required for estimation of DNBR, has been performed using W-3 Tong and OKB-Gidropress correlations implemented in TRIHEXFA.
Revalidation of Passalites Gloger, 1841 for the Amazon brown brocket deer P. nemorivagus (Cuvier, 1817) (Mammalia, Artiodactyla, Cervidae)

Mazama nemorivaga (Cuvier, 1817) is a gray brocket deer that inhabits the Amazon region. An assessment of previous studies revealed inconsistencies in its current taxonomic classification, suggesting the need for an update in its genus classification. A taxonomic repositioning of this species is proposed through the collection of a specimen from its type locality (French Guiana) with subsequent morphological (coloring pattern, body measurements, and craniometry), cytogenetics (G Band, C Band, conventional Giemsa, Ag-NOR staining, and BAC probe mapping), and molecular phylogenetic analysis (mitochondrial genes Cyt B of 920 bp, COI I of 658 bp, D-loop 610 bp), and comparisons with other specimens of the same taxon, as well as other Neotropical deer species. The morphological and cytogenetic differences between this and other Neotropical Cervidae confirm the taxon as a unique and valid species. The phylogenetic analysis evidenced the basal position of the M. nemorivaga specimens within the Blastocerina clade. This shows early diversification and wide divergence from the other species, suggesting that the taxon should be transferred to a different genus. A taxonomic update of the genus name is proposed through the validation of Passalites Gloger, 1841, with Passalites nemorivagus (Cuvier, 1817) as the type species. Future research should focus on evaluating the potential existence of other species within the genus Passalites, as suggested in the literature.
Muscles et géopolitique. Fragilité et résilience des corps et des grandes puissances dans James Bond et Mission impossible
Authors: Borzakian Manouk , Rouiaï Nashidil
Published: June 2023

Dans les années 1980, les « corps durs » du cinéma nord-américain, théorisés par Susan Jeffords, ont accompagné la politique reaganienne, incarnant une nation nord-américaine sûre d’elle et belliciste. Au lendemain des attaques du 11 septembre, deux franchises de cinéma d’aventure, James Bond et Mission impossible , reprennent le flambeau. Dans un monde présenté comme instable, menaçant et violent, des corps masculins musclés et puissants réalisent les cascades les plus ahurissantes et survivent aux pires agressions pour mener à bien leur mission. En cela, ils témoignent du retour d’une masculinité dominante tout en muscles et en puissance. Ce faisant, ils agissent comme des synecdoques corporelles : ces corps incarnent la perception d’elles-mêmes et de leur territoire de deux nations désireuses d’affirmer leur place au sein de l’ordre géopolitique mondial et de se convaincre de leur propre puissance et de leur caractère éternel.

Témoignage d’une période de transformation profonde du modèle sportif français, ce stade illustre dans le même temps de nouvelles relations entre secteur public et secteur privé en France. Au plan géographique, la construction de ce stade Matmut Atlantique interroge ce qu’il en est des liens entre centre-ville et zones d’activités, toponymie en naming et pratiques contemporaines de l’architecture internationale. Plus largement, ce travail participe des recherches qui démontrent l’importance renouvelée des métropoles en Europe dans un contexte économique néo-libéral.
Le fonds citoyen franco-allemand : le nouvel instrument de la coopération franco-allemande ?
Authors: Kurc Benjamin
Published: June 2023

Le Fonds citoyen franco-allemand est un nouvel outil issu du traité d’Aix-la-Chapelle, signé le 22 janvier 2019. Sa création s’inscrit dans la continuité du renforcement de la coopération franco-allemande amorcée par le traité de l’Élysée, signé en 1963. Ce dernier avait notamment permis la naissance de l’Office franco-allemande pour la Jeunesse, qui s’est imposé au fil des ans comme un acteur incontournable des relations franco-allemandes. Le traité d’Aix-la-Chapelle quant à lui a pour ambition de redynamiser la relation franco-allemande en approfondissant les champs d’action de celle-ci. Le Fonds citoyen franco-allemand est un des projets phares de ce traité. Il a pour but de raccrocher les deux peuples en soutenant des projets issus de la société civile. Le lancement du Fonds citoyen a été opéré le 16 avril 2020 en pleine pandémie. Le dispositif rencontre depuis le début un énorme succès. En deux ans son budget est passé de 2,4 à 5 millions € et il a pu soutenir en 3 ans plus de 1 500 projets. Sa flexibilité et son accessibilité en fait un outil sollicité par les acteurs et les actrices de la société civile ainsi que par les communes. Néanmoins, son succès croissant le place devant de nouveaux enjeux qui sont tout autant de promesses pour l’avenir.
De l’apprentissage de la langue du partenaire à la défense du plurilinguisme européen : quelles réalités et quelles ambitions pour le franco-allemand ?
Authors: Barrière Anne-Lise , Serrier Barbara , Volkwein Alice
Published: June 2023

La nouvelle feuille de route commune intitulée Stratégies pour le développement et l’apprentissage de la langue du partenaire publiée à l’occasion des 60 ans du Traité de l’Élysée traduit une inquiétude et une volonté de relance face à des effectifs d’apprenants en chute nette depuis plusieurs années – et ce malgré un soutien institutionnel et une action politique forte dont l’OFAJ est le principal acteur. Les autrices de cette contribution, enseignantes à Paris et à Berlin, proposent un état des lieux au plus près des réalités scolaires de ces deux régions-capitales à la fois comparables en termes de taille et de diversité de population mais bien différentes quant à l’organisation et au pilotage de l’offre scolaire. L’approche croisée met en lumière et analyse les problématiques communes (raisons de la baisse des effectifs, situation des enseignants, soutien institutionnel) mais aussi les succès et échecs propres à chaque système scolaire. L’enseignement de la langue du partenaire est-il condamné à ne s’épanouir, en région parisienne comme à Berlin, que dans des filières spécifiques d’excellence destinées, ne serait-ce que par leur implantation géographique, à un public plutôt favorisé ? L’Europe ne peut se passer d’une politique ambitieuse d’éducation plurilingue. Les autrices explorent les pistes qu’offre l’expertise du franco-allemand pour la relancer.
Les premiers pas du RER métropolitain transfrontalier de Strasbourg : enseignements des expériences allemandes et suisses pour un renouveau de services ferroviaires métropolitains en France
Authors: Rousseau Marie-Léa , Guihéry Laurent
Published: June 2023

Les enjeux liés aux mobilités dans les aires métropolitaines concernent fondamentalement le report modal de la voiture individuelle vers le transport public, et plus particulièrement le transport ferroviaire. L’objectif est de réduire l’empreinte carbone mais aussi de réduire la congestion dans les accès au centre-ville. Il importe également de réduire le coût de la mobilité individuelle, qui n’a cessé de croître ces dernières années (prix de l’essence). Dans cette perspective, les RER métropolitains ont acquis une solide réputation d’alternative modale, en particulier dans les pays germaniques. Fin 2022, Strasbourg a mis en service un réseau de RER, avec des ramifications transfrontalières vers l’Allemagne, réseau qui connaît des débuts difficiles. Quels sont les enseignements des expériences allemandes mais également suisse - pour le développement des RER métropolitain en France ?
Plurilinguisme, entreprises, économie et société
Authors: Di Pardo Leon-henri Dana
Published: June 2023

In order to reduce the significant financial losses incurred by small and medium-sized European firms, mainly caused by the lack of personnel possessing the required plurilingual skills, two solutions are suggested: firstly, at the national level of each member state, the improvement of the internal efficiencies of foreign language educational policies and secondly, the immediate introduction of plurilingual communication strategies into European businesses. For a small and medium-sized firm, the ability to negotiate commercial transactions and provide product maintenance support directly in the language of the client (in any one of the 23 officially recognized European languages) is a strategic and fundamental maneuver which would successfully increase business exports, while ensuring that the firm fully benefits from the intra-European business trade composed of 500 million potential consumers. To achieve this, two innovative and promising propositions are put forward: on the regional level, the creation of a “European Resource Center for Plurilingual Business Trade” and a standardized diagnostic evaluation of the plurilingual skills of European citizens adapted to the various employment sectors.

Published: June 2023

L’objectif de la recherche Thermenvie est l’évaluation des représentations sociales de la population générale grand-nancéienne sur le concept de bien-être environnemental dans un contexte de création du centre Nancy thermal et de l’ouverture prochaine de cure thermale sur ce territoire. Un questionnaire a été élaboré et diffusé au grand public via les réseaux sociaux. Ont répondu 180 participants, de tous les âges, majoritairement des femmes (83 %). Une analyse de contenu manuelle et automatique des réponses a été réalisée. Elle confirme l’interaction entre cure thermale, santé, bien-être et environnement, ce qui converge vers une représentation holistique de la cure thermale et la considération de la santé un déterminant de l’interaction santé et environnement. Parmi les représentations les plus originales, on observe que pour les moins de 25 ans, la cure thermale est associée à la vieillesse, que l’air occupe une place importante chez les plus de 45 ans et que le jardin est associé au contexte thermal. Ces résultats ouvrent des perspectives visant à renforcer ou modifier les représentations du thermalisme dans la métropole du Grand Nancy : communications et attractivité pour les plus jeunes en rajeunissant l’image du thermalisme, réalisations concrètes visant à améliorer la qualité de l’air respiré, aménagement de jardins dans les espaces thermaux.

A Monitoring System for Elderly People Using WiFi Sensing with Channel State Information
Authors: Boudlal Hicham , Mohammed Serrhini  , Ahmed Tahiri
Published: June 2023

Healthcare professionals, industry, and academics have all recently expressed a strong interest towards WiFi sensing. These techniques could be used to identify critical occurrences that sensitive persons may suffer, such as falls, sleep abnor-malities, wandering behavior, respiratory illnesses, and irregular heart activity. In this paper, we propose a low-cost, non-intrusive method to remotely monitor el-derly people without deploying devices on their bodies in a given space, using channel state information (CSI) from passive WiFi detection. Specifically, we monitored variables such as sitting and standing activity, and experimental valida-tion in practical situations with variable occupants, various environmental set-tings, and interference from other WiFi devices demonstrates robustness and scalability. Our results suggest that the proposed method can be put into practical-real use to detect activity and alert emergency personnel immediately, providing rapid medical assistance, saving lives, minimizing damage, and reducing anxiety for elderly people residing alone.

Published: June 2023

This study discusses the analysis of various variables affecting vocational students' intention to use a Virtual Laboratory (VL) in remote learning. Based on the Technology Acceptance Model (TAM), perceived ease of use (PEU), and perceived usefulness (PU) as exogenous variables. At the same time, attitudes towards VL (A) as an intervening variable. This research was conducted in the learning process of the Power Electronics Practicum for vocational education students. This study involved 105 vocational students from the Industrial Electrical Engineering Study Program, at Universitas Negeri Padang. Research data were analyzed using Partial Least Square-Structural Equation Modeling (PLS-SEM). The study results showed that the exogenous variables (PEU, PU, & A) had a significant and positive effect (directly and indirectly through intervening variables) on vocational students' intentions to use the virtual laboratory to support the implementation of remote learning in the Power Electronics Practicum Course. These factors can be considered in determining the appropriate virtual laboratory application to be applied in the learning process.
Chemical and Morphological Analysis of Calcium Oxide (CaO) Powder from Sea Urchin (Diadema setosum) Shell
Authors: Jamilludin Muhammad Amir , Dinatha I Kadek Hariscandra , Supii Apri I. , Partini Juliasih , Kusindarta Dwi Liliek , Yusuf Yusril
Published: June 2023

Calcium carbonate (CaCO3) has been taken from sea urchin (Diadema setosum) shell and calcinated at several temperatures to obtain calcium oxide (CaO). X-Ray Fluorescence Spectroscopy (XRF) revealed that the powder from this shell had a high Ca level, which increased at a higher temperature. Fourier Transform Infrared Spectroscopy (FTIR) spectra agreed to an increase in Ca level that showed the presence of CaO at 900 °C and 1100 °C; otherwise, CaCO3 disappeared. Using Scanning Electron Microscopy (SEM), the powder morphology was more homogeneous at 900 °C and 1100 °C than at lower temperatures. This morphology was encouraged by decreasing particle size, indicating compound decomposition in the powder and Ca leaved.

Published: June 2023

El artículo presenta hallazgos etnográficos sobre el ensamblaje transnacional de la santería e ifá cubanas en cuatro contextos latinoamericanos. Siguiendo las biografías de los emigrados cubanos en ciudades intermedias y capitales de México, Perú, Bolivia y Chile, logramos conocer las dinámicas de una tradición religiosa en expansión, motivada por factores políticos, económicos y culturales que determinaron sus estilos de adaptación en cada uno de los espacios de asentamiento. En este sentido, se analizaron los procesos de legitimación e institucionalización mediados por la difusión colectiva y en medios de comunicación, la incorporación de usuarios indígenas y afrodescendientes, la formación de casas templo y familias rituales, la circulación de mercancías y las crecientes redes de agentes que se consolidaron entre cubanos y extranjeros en cada uno de los países de anclaje.

Authors: Sponza Stefano , Salvador Paolo
Published: June 2023

The Collared Pratincole Glareola pratincola has a large and fragmented breeding distribution in the Palearctic. In Italy it is an uncommon migrant breeder and the breeding sites are very patchily distributed and irregularly used, with most frequent occurrences in the N Adriatic, N Apulia, Campania, Sardinia and Sicily. We report a new breeding site for the species along the northern Adriatic coastline in the Marano and Grado Lagoon (Friuli Venezia Giulia region, NE Italy), which represents the first breeding evidence for the Friuli Venezia Giulia region.
NUDT5 promotes the growth, metastasis, and Warburg effect of IDH wild-type glioblastoma multiforme cells by upregulating TRIM47
Authors: Zhang Zi-Fa , Liu Shu-Ming
Published: June 2023

Objective:

To explore the regulatory mechanism of NUDT5 in glioblastoma multiforme (GBM).

Methods:

GEPIA database was used to predict the expressions of NUDT5 and tripartite motif family proteins 47 (TRIM47) in GBM patients. RT-qPCR and Western blot analyses were performed to examine NUDT5 expression in GBM cells. LN-229 cell proliferation, migration as well as invasion were estimated by CCK-8, colony formation, wound healing, and Transwell assays following interference with NUDT5. ECAR assay, L-lactic acid kit, glucose detection kit, and ATP detection kit were applied for the detection of glycolysis-related indexes. Co-immunoprecipitation experiment was carried out to verify the relationship between NUDT5 and TRIM47.

Results:

GEPIA database showed that NUDT5 expression was significantly increased in GBM patients. Inhibiting the expression of NUDT5 in GBM cells significantly suppressed the viability, proliferation, invasion, migration, and glycolysis of GBM cells. Moreover, TRIM47 was highly expressed in GBM cells and interacted with NUDT5. Overexpression of TRIM47 partially reversed the inhibitory effect of NUDT5 downregulation on the proliferation, metastasis, and glycolysis of GBM cells.

Conclusions:

NUDT5 promotes the growth, metastasis, and Warburg effect of GBM cells by upregulating TRIM47. Both NUDT5 and TRIM47 can be used as targets for GMB treatment.
Minimally Invasive Direct Coronary Artery Bypass and Percutaneous Coronary Intervention Followed by Transcatheter Aortic Valve Implantation: A Promising Concept in High-risk Octogenarians
Authors: Alozie Anthony , Öner Alper , Löser Benjamin , Dohmen Pascal M.
Published: June 2023

Objectives:

In this article, we present our initial clinical experience with staged minimally invasive direct coronary bypass (MIDCAB), percutaneous coronary intervention (PCI), and transcatheter aortic valve implantation (TAVI) in high-risk octogenarians (Hybrid).

Background:

The use of percutaneous techniques for managing structural heart diseases, especially in elderly high-risk patients, has revolutionized the treatment of structural heart diseases. These procedures are present predominantly being offered as isolated interventions. The feasibility, clinical benefit, and outcomes of combining these techniques with MIDCAB have not been sufficiently explored and have subsequently been underreported in the contemporary literature.

Methods:

Four consecutive octogenarians with severe aortic stenosis (AS) and complex coronary artery disease (CAD) that were at high risk for conventional surgery with extracorporeal circulation (ECC) were discussed in our Multidisciplinary Heart Team (MDH). Our MDH consisted of an interventional cardiologist, cardiac surgeon, and cardiac anesthesiologist. A hybrid approach with the alternative strategy comprising of MIDCAB, PCI, and TAVI in a staged fashion was agreed on. All 4 patients had both PCI/stenting and MIDCAB prior to deployment of the TAVI-prosthesis.

Results:

From January 2019 to December 2020, 4 consecutive patients aged between 83 and 85 (3 male/1 female) years were scheduled for MIDCAB/PCI followed by percutaneous treatment of severe symptomatic AS. Intraoperatively, one patient was converted to full sternotomy, and surgery was performed by off-pump coronary artery bypass grafting. The overall procedural success rate was 100% in all 4 patients with resolution of their initial presenting cardiopulmonary symptoms. There were no severe complications associated with all hybrid procedures. There was no 30-day mortality in all patients. All patients were discharged home with a median hospital stay ranging between 9 and 25 days. All patients have since then been followed-up regularly. There was one noncardiac-related mortality at 6-months postsurgery. All other patients were well at 1-year follow-up with improved New York Heart Association Class II.

Conclusions:

In a selected group of elderly, high prohibitive risk patients with CAD and severe symptomatic AS, a staged approach with MIDCAB and PCI followed by TAVI can be safely performed with excellent outcomes. We advocate a MDH-based preliminary evaluation of this patient cohort in selecting suitable patients and appropriate timing of each stage of the hybrid procedure.

Published: June 2023

Background:

Low cardiac output is a common complication following cardiac surgery and it is associated with higher mortality in the pediatric population. A gold standard method for cardiac output (CO) monitoring in the pediatric population is lacking. The present study was conducted to validate cardiac output and cardiac index measured by transthoracic echocardiography and Pressure recording analytical method, a continuous pulse contour method, MostCare Up in postoperative pediatric cardiac surgical patients.

Materials and Methods:

This was a prospective observational clinical study conducted at a tertiary care hospital. A total of 23 pediatric patients weighed between 2 and 20 kg who had undergone elective cardiac surgery were included in the study.

Results:

Spearman’s correlation coefficient of CO between transthoracic echocardiography (TTE) and Pressure Recording Analytical Method (PRAM) showed of positive correlation (r = 0.69, 95% Confidence interval 0.59-0.77, P < 0.0001) Linear regression equations for CO between TTE and PRAM were y = 0.55 + 0.88x (R2 = 0.46, P < 0.0001). (y = PRAM, x = TTE), respectively. Bland- Altman plot for CO between TTE and PRAM showed a bias of -0.397 with limits of the agreement being -2.01 to 1.22. Polar plot analysis showed an angular bias of 6.55° with radial limits of the agreement being -21.46 to 34.58 for CO and angular bias of 6.22° with radial limits of the agreement being -22.4 to 34.84 for CI.

Conclusion:

PRAM has shown good trending ability for cardiac output. However, values measured by PRAM are not interchangeable with the values measured by transthoracic echocardiography.

Published: June 2023

Background:

Clearance of tissue carbon dioxide by circulation is measured by venous to arterial carbon dioxide partial pressure difference (AVCO2) and is correlated with cardiac output (CO) in critically ill adult patients. This study aimed to correlate AVCO2 with other CO indices like arteriovenous oxygen saturation difference (AVO2), central venous oxygen saturation (ScVO2), and serum lactate in pediatric patients undergoing intracardiac repair (ICR) for tetralogy of Fallot (TOF).

Methods:

We conducted a prospective observational study in 50 patients, of age 5 months to 5 years, undergoing ICR for TOF and analyzed AVO2, AVCO2, ScVO2, and lactate from arterial and venous blood gas pairs obtained at different time intervals from admission to pediatric intensive care unit (PICU) (T0), at 6 h (T1), 12 h (T2), 24 h (T3), and 48 h (T4) postoperatively. Bivariate correlations were analyzed using Pearson for parametric variables.

Results:

Admission AVCO2 was not correlated with AVO2 (R2 = 0.166, P = 0.246), ScVO2 (R2 = -2.2, P = 0.124), and lactate (R2 = -0.07, P = 0.624). At T1, AVCO2 was correlated with AVO2 (R2 = 0.283, P = 0.0464) but not with ScVO2 (R2 = - 0.25, P = 0.079) and lactate (R2 = -0.07, P = 0.623). At T2, T3 and T4, AVCO2 was correlated with AVO2 (R2 = 0.338,0.440 & 0.318, P = 0.0162, 0.0013, and 0.024), ScVO2 (R2 = - 0.344, - 0.488, and -0.366; P = 0.0143, <0.0001, and 0.017), and lactate (R2 = 0.305, 0.467 and 0.607; P = 0.0314, 0.00062 and <0.0001). AVCO2 was negatively correlated with ScVO2. No correlation observed between admission AVCO2 and mechanical ventilation duration. Two nonsurvivors had higher value of admission AVCO2 compared to survivors.

Conclusion:

AVCO2 is correlated with other CO surrogates like AVO2, ScVO2, and lactate in pediatric patients undergoing ICR for TOF.
