Easier material management - at what cost?
Authors: Liljegren Lovisa
Published: December 2022

Intelligent Material Management System, IMMS, was developed in a collaboration between Lyngsoe Systems, a commercial company, and public libraries in Aarhus and Copenhagen, Denmark, with the aim to reduce the time staff spend on managing library materials. The aim of this article is to shed light on what IMMS means for the library practices and hence for the librarian profession. Two research questions will guide the analysis: How do librarians and IMMS interplay at the public library in Copenhagen, Denmark? How does the implementation of IMMS impact the library practices at the branch libraries in Copenhagen, Denmark? With the theoretical lens of practice theory, the article shows how new norms and rules as well as new tools and objects are implemented with IMMS. Librarians need to be able to work with the new objects and tools, the new norms and to create an inspiring library room for library users. Their relation to collection management is changed, and their ability to evaluate materials is not needed in the same way when it comes to selection of titles for the collection. This sometimes creates a tension between the librarian and the system, especially when the librarians’ role in the practice is to perform the decision-making by the algorithm, and not to use their skills to evaluate resources.
Entrevista con Luis Camnitzer: conversaciones sobre los imaginarios pandémicos, arte y pedagogía
Authors: Martínez-Rodríguez Pamela
Published: December 2022

En esta entrevista realizada al artista y educador Luis Camnitzer en el presente año, se abordan las problemáticas generadas por la pandemia en el ámbito cultural y pedagógico. Para Camnitzer la pandemia y la perspectiva de una “nueva normalidad” supone un desafío para la creación, la pedagogía y las instituciones culturales que debe ser asumido desde la capacidad del arte y del artista de generar conocimiento sobre lo que desconoce. Es aquí donde Luis Camnitzer ubica el punto encuentro entre el arte, la pedagogía y el museo.
Cordón de Memoria: la identidad como palabra clave
Authors: Albar Javier , Martínez-Vérez María Victoria , López-Méndez Lorena , Pallarès-Piquer Marc
Published: December 2022

El presente artículo recoge los resultados del proyecto artístico Cordón de Memoria, haciendo referencia a los rasgos que nos distinguen como únicos y nos igualan como especie. El objetivo principal es indagar en la construcción del yo en relación con el mundo. Dicho proyecto está enmarcado en el Máster en Educación Artística en Instituciones Sociales y Culturales, el cual, pretende establecer vínculos entre la expresión artística, como herramienta mediadora, y la realidad en la que el alumnado universitario desarrollará sus competencias, generando aprendizajes horizontales aplicables en su desempeño profesional. El proyecto parte de una revisión bibliográfica dirigida a determinar las diferencias entre los conceptos de Id-entidad (identificación) e Id-éntico (similitud). El resultado de dicho análisis bibliográfico muestra un patrón de hitos vitales comunes a la especie, a la par que una divergencia respecto al significado otorgado a los mismos por los actores sociales. Posteriormente, con el fin de representar y analizar los procesos de identidad de los participantes, se utilizan, de forma combinada, dos técnicas expresivas: la escritura creativa y la monotipia; y dos de investigación: la observación documental y el análisis cualitativo de panel. Los resultados del presente estudio muestran como en el marco del ciclo vital, las personas realizan aprendizajes diferenciales que determinan la identidad.
Pensar y sentir en el aula: diseño de un programa para fomentar la creatividad visual en la formación de maestros de Primaria
Authors: Ortega-Cubero Inés , García-Romero Ángel , Coca Pablo
Published: December 2022

En este artículo se describe una propuesta de aula planteada a alumnos de Grado en Educación Primaria de una universidad pública, durante los últimos cuatro cursos. Como sustento de esta propuesta práctica, enfocada al desarrollo creativo, se ofrece un marco teórico que aborda la cuestión de la creatividad en el ámbito de la escuela primaria, estableciendo nexos entre los conocimientos, actitudes y habilidades de los maestros y las posibilidades de creación que proponen a los escolares. También se ofrecen al lector algunas de las soluciones artísticas planteadas por los alumnos de grado, a modo de ejemplo, así como su reflexión sobre los logros obtenidos y sus consideraciones en torno a la utilidad de dicho enfoque en el futuro desempeño de su labor docente. Usando una metodología cualitativa, fundamentalmente basada en el análisis crítico documental, observamos cómo los alumnos interiorizan los valores del trabajo artístico desarrollado en el taller colectivo, tanto para establecer unas óptimas relaciones interpersonales como para potenciar cualidades personales de independencia y pensamiento autónomo. Sin embargo, siguen apreciando el taller de arte como un entorno de aprendizaje y experimentación esencialmente diferente y, por tanto, les resulta difícil conectar estas actividades con otras áreas de conocimiento. Por todo ello, es necesario continuar profundizando en las experiencias artísticas del alumnado en el aula real para concebir un marco formativo adecuado que ayude a integrar la creatividad en el contexto escolar.

La Investigación Basada en las Artes como espacio de aprendizaje rizomático. Reflexiones situadas a partir de la postal/collage
Authors: Espinosa Gabriela , Onsès-Segarra Judit
Published: December 2022

El presente artículo da cuenta de la experiencia de una estudiante de máster durante un seminario de Investigación Basada en las Artes (IBA). Ello se presenta a través de cuatro postales-collages que dialogan con cuatro reflexiones situadas, donde se van sucediendo los diferentes encuentros realizados en el marco del seminario desde un ejercicio de encarnación y materialización de lo que supone llevar a cabo una IBA. Dando cuenta de sus enredos, conversaciones (internas y externas), vinculaciones con la vida, basándose en una ontología conectada a la epistemología, la metodología y la ética.
A través de estas relaciones, se rescatan y crean aprendizajes y reflexiones que desplazan al sujeto hablante para llevarlo a un rizoma de multiplicidades, capas, voces, espacios, tiempos y materias. Donde las situaciones propuestas por la docente y dos investigadoras invitadas se entrelazan y reconfiguran según las circunstancias, las acciones e iniciativas del grupo de participantes. Así, el seminario de IBA actúa como detonante que permite reflexionar sobre diferentes dimensiones como son las prácticas artísticas, la indagación basada en las artes y la educación vinculadas al bagaje, experiencias y modos de ser, decir, sentir y devenir de la estudiante desde una subjetividad-en-relación con el grupo, así como reconfigurar sus modos de aprender. Finalmente, se destaca la importancia de la investigación basada en las artes como posibilitadora de otros modos de investigar.
Un maestro del grafiti. Street Art y creatividad en la obra de Dridali
Authors: Huerta Ricard
Published: December 2022

Dridali es el nombre artístico con el que firma sus obras Adrián Mateo. La elección está vinculada a su admiración por la obra de Salvador Dalí, utilizando así un acrónimo que enlaza con parte de las letras de su nombre. La formación de este joven artista está vinculada a los estudios de Magisterio, una titulación universitaria que decidió estudiar por su vocación docente. Nuestro artista urbano nacido en 1995 en Valencia se inició en el mundo del arte urbano en abril de 2017. Lo que empezó como un hobby se ha convertido en su forma de vida, creando su propia empresa como artista independiente. Su obra se centra en la creación de rostros de personas con un estilo hiperrealista que lo caracteriza, usando principalmente la técnica del spray.

Eiximenis i Boeci en el llibre sapiencial català traduït al castellà per Jacob Zadique d’Uclés en 1402
Authors: Conca Maria , Guia Josep
Published: December 2022

Resum: Presentem la descoberta d’una obra catalana sapiencial perduda, que va ser traduïda al castellà per Jacob Zadique d’Uclés, en 1402, per encàrrec de Lorenzo Suárez de Figueroa, mestre de l’Orde de Sant Jaume. L’obra continua desapareguda, però hi ha un testimoni documental de la seva existència i l’hem poguda identificar completament i detallada: un llibre que va ser escrit molt probablement a València, entre 1390 i 1402, format per una selecció d’enunciats sapiencials del Dotzè llibre del Crestià (1387), de Francesc Eiximenis, i de la Consolació de filosofia, de Boeci, en traducció catalana de Ginebreda (1390), a més d’alguns proverbis i apotegmes afegits. La descoberta ha estat possible, a partir de la traducció conservada, gràcies a l’aplicació del mètode de concordances fràsiques, ben útil per a la determinació de dependències, fonts i autories. Paraules clau: Literatura medieval catalana, Literatura sapiencial, Traducció, Paremiologia contrastivaAbstract: We present the discovery of a lost Catalan sapiential work, which will be translated into Spanish by Jacob Zadique d’Uclés, in 1402, commissioned by Lorenzo Suarez de Figueroa, master of the Order of Saint James. The work continues to disappear, but there is a documentary testimony of its existence and we could identify it completely and in detail: a book most likely composed in Valencia, between 1390 and 1402, consisting of a selection of wisdom statements from Eiximenis’s Dotzè llibre del Crestià (1387), from Boeci’s Consolació de filosofia, in Catalan translation by Ginebreda (1390), plus some added proverbs and apothegms. The discovery was made possible, from the preserved translation, by the application of the method of phrasal concordances, very useful for the determination of dependencies, sources and authors. Keywords: Medieval Catalan literature, Wisdom literature, Translation, Contrastive paremiology.
Medea in controluce: La infanticida di Caterina Albert (1898) e un’infanticida ad Alghero nel 1735
Authors: Compagna Anna Maria
Published: December 2022

Riasunto: L’articolo focalizza il discorso su come sia la letteratura che le realtà marginale della microstoria si connettano fra loro e si possano collegare col mito, anche singolarmente. Si pensi a La infanticida di Caterina Albert (1898) e a un infanticidio attestato ad Alghero nel 1735. Nelle due protagoniste è possibile vedere Medea in controluce? Nel primo caso una realtà documentata attraverso la letteratura si connetterebbe al mito. Nel secondo una microstoria si collegherebbe direttamente al mito, senza passare attraverso la letteratura. Il mito non è in primo piano, non è il mezzo per rappresentare, condannare una realtà atroce sublimandola, come in Ovidio, ma esso appartiene al contesto culturale entro il quale la società si muove, costituendone l’atmosfera non sempre percepita, anche se presente. Il percorso è inverso: non più dal mito letterario alla realtà, ma dalla realtà storica al mito, sia pure attraverso la letteratura, a ulteriore conferma di come miti e leggende stiano a fondamento della cultura mediterranea, e non solo. E, infine, un altro dubbio: in questo ipotetico riferimento al mito classico e mediterraneo, si può vedere nell’Albert, sempre in controluce, un anticipo di Noucentisme?Parole chiave: La infanticida, Caterina Albert, processi dell’Inquisizione, Medea, microstoria, letteratura, mito.Abstract: The article focuses the discussion on how both literature and the marginal realities of micro-history connect with each other and with myth, even individually. Think of Caterina Albert’s La infanticida (1898) and an infanticide attested in Alghero in 1735. In the two protagonists, is it possible to see Medea in backlight? In the first case, a reality documented through literature would be connected to the myth. In the second, a micro-history would connect directly to the myth, without going through literature. The myth is not in the foreground, it is not the means to represent, condemn an atrocious reality by sublimating it, as in Ovid, but it belongs to the cultural context within which society moves, constituting its atmosphere that is not always perceived, even if present. The path is reversed: now, no from literary myth to reality, but from historical reality to myth, albeit through literature, further confirming how myths and legends are at the foundation of Mediterranean culture, and beyond. And, finally, another doubt: in this hypothetical reference to the classical and Mediterranean myth, can we see in the Albert, always in backlight, an anticipation of Noucentisme?Keywords: La infanticida, La infanticida, Caterina Albert, trials of the Inquisition, Medea, micro-history, literature, myth.
Dues Galatees mediterrànies: El mite de Pigmalió a Pinotxo i a La salvatge
Authors: Gort Paniello Marta
Published: December 2022

Resum: El tema de la transformació és un tòpic en la història de la literatura i en trobem un clar exponent en el mite de Pigmalió, la primera versió del qual es troba recollida en les Metamorfosis d’Ovidi. En aquest estudi es comparen dues reinterpretacions del mite de Pigmalió fetes per escriptors de la Mediterrània: Les aventures de Pinotxo de Carlo Collodi (1883) i La salvatge. Elegia de Dolores Mendoza d’Isabel-Clara Simó (1993). Aquestes obres van ser escrites amb més de cent anys de separació i, tot i que els escriptors comparteixen certs referents, cadascun s’ha sentit atret per influències més properes al seu context. L’estudi se centra fonamentalment en la figura femenina, i els resultats de l’anàlisi mostren que Collodi i Simó representen dues Galatees ben diferents. D’una banda, Pinotxo segueix la imatge més tradicional en tant que acaba satisfent el desig del seu creador, Gepetto. D’altra banda, Dolores és una Galatea més revolucionària perquè, finalment, s’oposa a la voluntat del seu Pigmalió, Joaquim, i lluita per aconseguir ser lliure i independent.Paraules clau: Literatura comparada, Transformació, Galatea, Pinotxo, La salvatge.Abstract: The theme of transformation is a recurrent topic in literature and we find a clear exponent in the Myth of Pygmalion, the first version of which was gathered by Ovid in the Metamorphosis. This study compares two reinterpretations of the story of Pygmalion and Galatea written by two Mediterranean writers: Les aventures de Pinotxo by Carlo Collodi (1883) and La salvatge. Elegia de Dolores Mendoza by Isabel-Clara Simó (1993). These works were written by more than a century of distance and, although the writers have some literary sources in common, each one has feel attracted to other influences closer to their context. The paper focuses mostly in the female figures of the story and results from the literary analysis prove that Collodi and Simó represent two very different Galateas. On the one hand, Pinotxo follows the traditional image of Galatea, as long as he ends satisfying the desires of his creator, Gepetto. On the other hand, Dolores is a more revolutionary Galatea because, finally, she disobeys the wish of his Pygmalion, Joaquim, and fights for becoming someone independent and free. Keywords: Comparative literature, Transformation, Galatea, Pinocchio, La salvatge.

IN VITRO EVALUATION OF A PILE LOOP KNITTED SCAFFOLD FOR MYOCARDIAL TISSUE ENGINEERING USING C2C12 CELLS
Authors: Haroğlu Derya
Published: December 2022

Pile loop knitted scaffold has attracted attention for being used as a three dimensional (3D) biocompatible material particularly for the application of myocardial tissue engineering. In this research, nonintermingled, textured polyethylene terephthalate (PET) multifilament yarn with a filament count of 48 was used for producing a pile loop knit structure to investigate if structure could provide an appropriate microenvironment for the seeded murine C2C12 myoblasts in case of increasing in filament diameter (20.7 micron versus 9.1 micron from the previous study). The resulting structure had a pore network mainly consisting of macropores of 100-200 µm that were well interconnected with micropores (<90 µm). Furthermore, the mean values of the Young’s modulus of the structures at 20% strain were 240.67 kPa in the warp direction, and 85.73 kPa in the weft direction, which can be claimed not to be far from those declared in the literature for the human heart muscle. In addition, the cyclic loading-unloading test revealed no creep in the fabric after 100 cycles. According to the results of the WST-1 assay, the 48 filament-based scaffold was non-cytotoxic for C2C12 cells that were able to proliferate properly on the scaffold, which was visualized by SEM and confocal images. In this respect, pile loop knit structures keep promising results for being used as a cardiac patch.

MRI and MR Arthrography Imaging of the Pathologies of the Wrist: A Pictorial Essay
Authors: Reghunath Anjuna , Singh Dharmendra Kumar , Aggarwal Anuj , Babbar Nikhil , Choudhary Rahul , Surya Samar
Published: December 2022

Magnetic Resonance Imaging (MRI) has a special advantage over radiographs and Computed Tomography (CT) in evaluating an anatomically complex structure like wrist, owing to its excellent soft-tissue resolution and multiplanar imaging functionality. MR arthrography further improves the diagnostic value of MRI by virtue of its meticulous depiction of even small tears involving the Triangular Fibrocartilage Complex (TFCC), intrinsic and extrinsic ligaments of the wrist. This article focuses on the MRI and MR arthrography illustration of various traumatic as well as non traumatic pathologies affecting the wrist region and is mainly intended to educate the residents by comprehensively reviewing the imaging features of the major afflictions of this complex joint in a systematic fashion using checklists.
ТРАКТАТ «СПОР МЕЖДУ СВЯЩЕННИКОМ И РЫЦАРЕМ» И ПРОБЛЕМА ЕГО ЛИТЕРАТУРНОЙ ФОРМЫ, "Средние века"
Authors: Пономарева М.А.
Published: December 2022

В статье рассматриваются происхождение, бытование, литературные и идейные особенности анонимного диалога «Спор между священником и рыцарем», созданного во Франции на рубеже XIII–XIV вв., но получившего самое широкое распространение в странах Западной Европы в позднее Средневековье и раннее Новое время. Диалог относился к войне памфлетов эпохи противостояния французского короля Филиппа IV Красивого и папы римского Бонифация VIII, и потому его главной темой стало разграничение прав светской и церковной власти. В статье доказывается, что эта идейная составляющая «Спора» оказалась тесно связана с его риторической структурой, следующей за пособиями по риторике, созданными во второй половине XIII в. Выявление этой связи позволяет прочесть «Спор» не только с идейной, но и с формальной, литературной точки зрения, и дает возможность говорить о принципах работы его автора. В приложении к статье приводится комментированный перевод «Спора между священником и рыцарем» на русский язык.
ДИСПЕРСИОННЫЕ СВОЙСТВА СОСТАВНОЙ ПЛАСТИНЫ ИЗ НЕОДНОРОДНЫХ ПЬЕЗО- И ДИЭЛЕКТРИЧЕСКОГО СЛОЕВ, "Наука юга России"
Authors: Белянкова Т.И. , Ворович Е.И. , Калинчук В.В.
Published: December 2022

Предложен подход к исследованию дисперсионных свойств составной пластины из неоднородных пьезоэлектрического и диэлектрического слоев. При моделировании неоднородности слоев использована двухкомпонентная модель с функционально градиентным изменением свойств от параметров основного материала до параметров другого материала. Внешние поверхности пластины свободны от механических напряжений. Электрически они могут быть как открытыми и граничащими с вакуумом, так и короткозамкнутыми. На примере задачи о сдвиговых, инициированных бесконечно удаленным источником, гармонических колебаниях пластины исследовано влияние характера неоднородности, ее локализации и размера области перехода одного материала в другой на дисперсионные свойства структуры в широком диапазоне частот. Результаты исследования приведены в безразмерных параметрах, оформлены в виде графиков и могут представлять определенный интерес при разработке, проектировании и оптимизации функционально ориентированных материалов и структур, используемых при создании новых микро- и наноразмерных приборов и устройств на поверхностных акустических SH-волнах с высокими эксплуатационными характеристиками.
Ionic Covalent Organic Frameworks‐Derived Cobalt Single Atoms and Nanoparticles for Efficient Oxygen Electrocatalysis
Authors: Guo Jiaming , Li Wenqiong , Xu Yuncun , Mao Yanqi , Mei Zhiwei , Li Haihan , He Yun , San Xingyuan , Xu Kui , Liang Xiaoguang
Published: December 2022

Metal single atoms show outstanding electrocatalytic activity owing to the abundant atomic reactive sites and superior stability. However, the preparation of single atoms suffers from inexorable metal aggregation which is harmful to electrocatalytic activity. Here, ionic covalent organic frameworks (iCOFs) are employed as the sacrificial precursor to mitigate the metal aggregation and subsequent formation of bulky particles. Molecular dynamics simulation shows that iCOFs can trap and confine more Co ions as compared to neutral COFs, resulting in the formation of a catalyst composed of Co single atoms and uniformly distributed Co nanoparticles (CoSA&CoNP‐10). However, the neutral COFs derive a catalyst composed of Co atomic clusters and large Co nanoparticles (CoAC&CoNP‐25). The CoSA&CoNP‐10catalyst exhibits higher oxygen bifunctional electrocatalytic activities than CoAC&CoNP‐25, coinciding with the density functional theory results. Taking the CoSA&CoNP‐10as the air cathode in Zn–air batteries (ZABs), the aqueous ZAB presents a high power density of 181 mW cm−2, a specific capacity of 811 mAh g−1as well as a long cycle life of 407 h at a current density of 10 mA cm−2, while the quasi‐solid state ZAB displays a power density of 179 mW cm−2and the cycle life of 30 h.
3D Interconnected Honeycomb-Like Multifunctional Catalyst for Zn–Air Batteries
Authors: Jin Tianxu , Nie Junli , Dong Mei , Chen Binling , Nie Jun , Ma Guiping
Published: December 2022

Developing high-performance and low-cost electrocatalysts is key to achieve the clean-energy target. Herein, a dual regulation method is proposed to prepare a 3D honeycomb-like carbon-based catalyst with stable Fe/Co co-dopants. Fe atoms are highly dispersed and fixed to the polymer microsphere, followed by a high-temperature decomposition, for the generation of carbon-based catalyst with a honeycomb-like structure. The as-prepared catalyst contains a large number of Fe/Co nanoparticles (Fe/Co NPs), providing the excellent catalytic activity and durability in oxygen reduction reaction, oxygen evolution reaction and hydrogen evolution reaction. The Zn-air battery assembled by the as-prepared catalyst as air cathode shows a good charge and discharge capacity, and it exhibits an ultra-long service life by maintaining a stable charge and discharge platform for a 311-h cycle. Further X-ray absorption fine structure characterization and density functional theory calculation confirms that the Fe doping optimizes the intermediate adsorption process and electron transfer of Co.
The deserving or undeserving rich? New survey evidence on multimillionaire households in Europe
Authors: Korom Philipp
Published: December 2022

This article addresses two questions. First, when do people consider the rich to be deserving? A literature survey reveals that it is first and foremost the origin of great wealth that determine public attitudes towards the rich. Rich people “deserve” to be rich if their wealth is perceived as having resulted from competence and hard work rather than from inheritance. Second, who are the rich? Drawing on data from the second wave of the European Household Finance and Consumption Survey (HFCS), it is found that multimillionaire households benefit disproportionately from wealth transfers. Large gifts and bequests alone, however, are not good predictors of rich household status. It is rather the highly educated top heir running a (family) business that best represents the rich in Europe. Such entrepreneurs who benefit from earned and unearned financial resources neither fully correspond to nor contradict the existing public beliefs in the “deservingness” of the rich. It is argued that, while still underresearched, it is the “hybrid rich” that dominate in the twenty-first-century capitalism that is marked by historically high levels of wealth inequality alongside inefficiencies in tax systems.
Machine learning can aid in prediction of IDH mutation from H&E-stained histology slides in infiltrating gliomas

Published: December 2022

While Machine Learning (ML) models have been increasingly applied to a range of histopathology tasks, there has been little emphasis on characterizing these models and contrasting them with human experts. We present a detailed empirical analysis comparing expert neuropathologists and ML models at predicting IDH mutation status in H&E-stained histology slides of infiltrating gliomas, both independently and synergistically. We find that errors made by neuropathologists and ML models trained using the TCGA dataset are distinct, representing modest agreement between predictions (human-vs.-human κ = 0.656; human-vs.-ML model κ = 0.598). While no ML model surpassed human performance on an independent institutional test dataset (human AUC = 0.901, max ML AUC = 0.881), a hybrid model aggregating human and ML predictions demonstrates predictive performance comparable to the consensus of two expert neuropathologists (hybrid classifier AUC = 0.921 vs. two-neuropathologist consensus AUC = 0.920). We also show that models trained at different levels of magnification exhibit different types of errors, supporting the value of aggregation across spatial scales in the ML approach. Finally, we present a detailed interpretation of our multi-scale ML ensemble model which reveals that predictions are driven by human-identifiable features at the patch-level.
“What are they talking about?” A sociocultural linguistic approach to practical task effectiveness
Authors: Hennah Naomi Louise
Published: December 2022

This case study demonstrates teaching and learning activities in the school laboratory, and employs talk moves for the direct assessment of practical task effectiveness. By adopting a sociocultural linguistic approach (SCLA), learning chemistry is understood to be a discursive process in which knowledge is constructed through social interaction and language. Thus, learning may be identified by attending to the language used in classroom discourse. The multimodal communication that took place during two acid and alkali practical lessons for learners aged 11 and 12 years was filmed and transcribed. Analysis of the transcripts revealed the language learning opportunities afforded by the tasks and demonstrated that school chemistry practical lessons can be understood in terms of three linguistic opportunities: introducing, using, and reflecting upon language. This lesson structure could be employed to plan more inclusive and equitable practical lessons which foreground language and value discussion equally to manipulating equipment. Recasting practical lessons as sites for learning and using the language of chemistry, key words introduced by the teacher are tracked and counted throughout the lesson to identify when they are used and by whom. The novel 3-part practical (3P) framework and multimodal discourse analysis are employed to assign the use of key words to the macroscopic, submicroscopic or symbolic level of thought. This analysis reveals the centrality of a results table to structuring talk and the detrimental effect of introducing novice learners to multiple levels of thought simultaneously. The Talk Identification (ID) Grid has been developed and used here to analyse student group discourses using talk moves to signpost learning in the domain of ideas and the domain of observables. Descriptors are provided to support instructors in identifying talk moves and how these moves relate to practical task effectiveness to target interventions that improve learning procedural and conceptual knowledge in the laboratory.

During our biochemical characterization of select bacterial phosphatases belonging to the haloacid dehalogenase superfamily of hydrolases, we discovered a strong bias of Salmonella YidA for glucose-1-phosphate (Glc-1-P) over galactose-1-phosphate (Gal-1-P). We sought to exploit this ability of YidA to discriminate these two sugar-phosphate epimers in a simple coupled assay that could be a substitute for current cumbersome alternatives. To this end, we focused on Gal-1-P uridylyltransferase (GalT) that is defective in individuals with classical galactosemia, an inborn disorder. GalT catalyzes the conversion of Gal-1-P and UDP-glucose to Glc-1-P and UDP-galactose. When recombinant YidA was coupled to GalT, the final orthophosphate product (generated from selective hydrolysis of Glc-1-P by YidA) could be easily measured using the inexpensive malachite green reagent. When this new YidA-based colorimetric assay was benchmarked using a recombinant Duarte GalT variant, it yielded kcat/Km values that are ~2.5-fold higher than the standard coupled assay that employs phosphoglucomutase and glucose-6-phosphate dehydrogenase. Although the simpler design of our new GalT coupled assay might find appeal in diagnostics, a testable expectation, we spotlight the GalT example to showcase the untapped potential of sugar-phosphate phosphatases with distinctive substrate-recognition properties for measuring the activity of various metabolic enzymes (e.g. trehalose-6-phosphate synthase, N-acetyl-glucosamine-6-phosphate deacetylase, phosphofructokinase).

Surgical hip dislocation (SHD) is a powerful and safe approach used to address pathologic lesions around the hip joint, and therefore, many studies have been conducted in this field. However, no bibliometric studies regarding the global research trend concerning SHD have been studied yet. This study aims to determine the research status in the field of SHD research between 2001 and 2021. The publications related to SHD from 2001 to 2021 were retrieved from the Web of Science Core Collection. Three bibliometric tools were used for this study. The main analyses include publication counts, contributions of countries, institutions, authors, journals and funding agencies, as well as analyses on clustering of references and keywords. In total, 498 articles were identified. The annual publication counts of SHD showed an ascending tendency as a whole. The United States has the most prominent contributions, with the most number of publications and the highest value of H-index. The University of Bern was the organization that produced the most literature. Professors Ganz R, Siebenrock KA, Tannast M, Steppacher SD and Leunig M were the core authors in this field. The most productive journal was Clinical Orthopaedics and Related Research. Burst keyword detection suggested that the following research directions, including ‘surgical hip dislocation’, ‘outcome’, ‘fixation’ and ‘pain’, are considered the research hotspots and deserve more attention. In conclusion, this is the first bibliometric analysis that provides a comprehensive overview of SHD research, which may assist investigators in exploring new directions for this technique.

Strand-specific RNA-seq is a powerful tool for the discovery of novel transcripts, annotation of genomes, and profiling of gene expression levels. Tn5 transposase has been successfully applied in massive-scale sequencing projects; in particular, Tn5 adaptor modification is used in epigenetics, genomic structure, and chromatin visualization. We developed a novel dU-adaptor-assembled Tn5-mediated strand-specific RNA-sequencing protocol and compared this method with the leading dUTP method in terms of experimental procedure and multiple quality metrics of the generated libraries. The results showed that the dU-Tn5 method is easy to operate and generates a strand-specific RNA-seq library of comparable quality considering library complexity, strand-specificity, evenness, and continuity of annotated transcript coverage. We also evaluated the performance of the dU-Tn5 method in identifying nitrogen-responsive protein-coding genes and long non-coding RNAs in soybean roots. The results indicated that ~62–70% of differentially expressed genes detected from conventional libraries were also detected in dU-Tn5 libraries, indicating good agreement of our method with the current standard; moreover, their fold-changes were highly correlated (R>0.9). Thus, our method provides a promising ‘do-it-yourself’ stranded RNA-seq procedure for gene expression profiling.

Published: December 2022

Background

Primary central nervous system lymphomas (PCNSLs) have historically had dismal survival rates until the advent of high-dose methotrexate (HD-MTX) based chemotherapy regimens. With increasing prevalence of autoimmune disease and development of new immunosuppressants, a genetically distinct entity known as iatrogenic immunodeficiency-associated lymphoproliferative disorder (LPD) has emerged. Many of these cases arise following methotrexate use, challenging feasibility of standard HD-MTX regimens. The aim of this study was to further characterize this disorder and determine the optimal management strategy.

Methods

We describe a case of a 76-year-old female with iatrogenic immunodeficiency-associated PCNSL successfully treated with surgical resection followed by an antiviral and rituximab based regimen. We then performed a systematic literature review and identified 58 cases of non-transplant iatrogenic immunodeficiency-associated LPD involving the CNS. We used a linear probability statistical model to determine correlations with outcome.

Results

Natalizumab was associated with EBV negative tumors (P = .023), and EBV positive tumors were associated with improved outcomes (P = .016). Surgical resection was associated with improved outcomes (P = .032), although limited by potential confounding effect. Antiviral treatment (P = .095), rituximab (P = .111), and stem cell transplant (SCT) (P = .198) showed a trend toward improved outcomes. The remaining treatments including methotrexate showed no improvement.

Conclusion

We propose that surgical resection, rituximab, and antiviral treatment may be considered as an alternative to standard HD-MTX based regimens when managing iatrogenic immunodeficiency-associated LPD of the CNS. Further study through prospective cohort studies or randomized clinical trials is warranted.
“What do we want and how do we get there”: A comparative content analysis of First Nations Comprehensive Community Plans in British Columbia
Authors: Kobzik Juraj , Krawchenko Tamara
Published: December 2022

First Nations are important regional development actors, and yet their development ambitions and goals have often been ignored or poorly understood by settler governments. Since 2004, the Canadian federal government has supported First Nations governments and Tribal Councils to develop Comprehensive Community Plans (CCPs)—community planning documents that are meant to set priorities and guide development in the medium to long term. This study employs a quantitative content analysis of all publicly available CCPs and related strategic planning documents in British Columbia in order to understand development priorities and in doing so, reveals a mismatch between the interests of First Nations and settler governments.

Background and Purpose

Intracranial hemorrhage (ICH) is a common life‐threatening condition that must be rapidly diagnosed and treated. However, there is still a lack of consensus regarding treatment, driven to some extent by prognostic uncertainty. While several prediction models for ICH detection have already been published, here we present a deep learning predictive model for ICH prognosis.

Methods

We included patients with ICH (n = 262), and we trained a custom model for the classification of patients into poor prognosis and good prognosis, using a hybrid input consisting of brain CT images and other clinical variables. We compared it with two other models, one trained with images only (I‐model) and the other with tabular data only (D‐model).

Results

Our hybrid model achieved an area under the receiver operating characteristic curve (AUC) of .924 (95% confidence interval [CI]: .831‐.986), and an accuracy of .861 (95% CI: .760‐.960). The I‐ and D‐models achieved an AUC of .763 (95% CI: .622‐.902) and .746 (95% CI: .598‐.876), respectively.

Conclusions

The proposed hybrid model was able to accurately classify patients into good and poor prognosis. To the best of our knowledge, this is the first ICH prognosis prediction deep learning model. We concluded that deep learning can be applied for prognosis prediction in ICH that could have a great impact on clinical decision‐making. Further, hybrid inputs could be a promising technique for deep learning in medical imaging.

Published: December 2022

Objective

The aim of the study was to evaluate the effect of doxycycline‐ and dexamethasone‐doped collagen membranes on the proliferation and differentiation of osteoblasts.

Background

Collagen barrier membranes are frequently used to promote bone regeneration and to boost this biological activity their functionalization with antibacterial and immunomodulatory substances has been suggested.

Methods

The design included commercially available collagen membranes doped with doxycycline (Dox‐Col‐M) or dexamethasone (Dex‐Col‐M), as well as undoped membranes (Col‐M) as controls, which were placed in contact with cultured MG63 osteoblast‐like cells (ATCC). Cell proliferation was assessed by 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium (MTT) assay and differentiation by measuring the alkaline phosphatase (ALP) activity using spectrophotometry. Real‐time quantitative polymerase chain reaction was used to study the expression of the genes: Runx‐2, OSX, ALP, OSC, OPG, RANKL, Col‐I, BMP‐2, BMP‐7, TGF‐β1, VEGF, TGF‐βR1, TGF‐βR2, and TGF‐βR3. Scanning electron microscopy was used to study osteoblast morphology. Data were assessed using one‐way analysis of variance or Kruskal–Wallis tests, once their distribution normality was assessed by Kolmogorov–Smirnov tests (p > .05). Bonferroni for multiple comparisons were carried out (p < .05).

Results

Osteoblast proliferation was significantly enhanced in the functionalized membranes as follows: (Col‐M < Dex‐Col‐M < Dox‐Col‐M). ALP activity was significantly higher on cultured osteoblasts on Dox‐Col‐M. Runx‐2, OSX, ALP, OSC, BMP‐2, BMP‐7, TGF‐β1, VEGF, TGF‐βR1, TGF‐βR2, and TGF‐βR3 were overexpressed, and RANKL was down‐regulated in osteoblasts cultured on Dox‐Col‐M. The osteoblasts cultured in contact with the functionalized membranes demonstrated an elongated spindle‐shaped morphology.

Conclusion

The functionalization of collagen membranes with Dox promoted an increase in the proliferation and differentiation of osteoblasts.

Published: December 2022

Chronic pain affects the quality of life of those affected. The need to investigate alternative and complementary methods to the pharmacological one to alleviate chronic pain is evident, so virtual reality and binaural tones have become a topic of interest in this field in recent years. This study aims to analyze the contributions of the combination of these two techniques in pediatric patients with chronic pain. For this, data on psychophysiological responses (heart rate and galvanic skin response) and pain perception are collected during and after interaction with this technology using a mixed pre- and posttest experimental methodology. The physiological data and answers in the Pediatric Pain Questionnaire (PPQ) have been collected in a sample of n = 13 healthy participants and n = 9 pediatric patients with chronic pain. The results show a significant difference between baseline and after applying virtual reality and binaural beats, md = 1.205 (t = 3.32;

). There are great effects on the perception of chronic pain if virtual reality and binaural beats are combined, even greater than with virtual reality alone, making this combination of technologies a very useful tool to be exploited for the management of chronic pain in pediatric patients with rheumatic diseases.
