Glioblastoma multiform with primitive neuronal component, radiological and histology features: a case report
Authors: Valbuena Santiago , Ortega Alejandro , Centeno Macarena , Rimbau Jordi Manuel 
Published: November 2021

AbstractBackgroundGlioblastoma multiform with primitive neuronal component (GBM-PNC) has been recently defined as a rare variant of glioblastoma multiform (GBM), which shows characteristically pathological pattern of less differentiated areas with small blue cell morphology and neuroectodermic immunophenotype. New studies emphasize its characteristics and differences, which have become vitally important due to the changes in therapeutic management.Case presentationWe present the case of 57-year-old male patient who onset symptoms were secondarily widespread partial seizures and expression aphasia. Brain magnetic resonance imaging (MRI) reported left enhanced temporal infiltrating lesion, requiring surgery twice throughout two years. At first surgery, pathological samples revealed embryonic tumor of the central nervous system (grade IV, WHO 2016), so PACKER protocol consisting of CSRT (craniospinal radiation) plus weekly vincristine followed by 8 cycles of cisplatin, lomustine and vincristine usually used for medulloblastomas or other primitive neuroectodermal tumors was started. However, due to reappearance of symptoms and progression in MRI, reoperation was performed with definitive diagnosis of GBM-PNC (Grade IV, WHO 2016) and switched to STUPP protocol.ConclusionsIt is important to take into account the chance of this entity when histological, radiological and intraoperative findings orient toward a primitive neural tumor since the presence of GBM could be overlooked leading to mistakes in diagnosis and the therapeutic orientation.

Objectives: This study aimed to develop a fully automated human identification method based on a convolutional neural network (CNN) with a large-scale dental panoramic radiograph (DPR) data set. Methods: In total, 2760 DPRs from 746 subjects who had 2–17 DPRs with various changes in image characteristics due to various dental treatments (tooth extraction, oral surgery, prosthetics, orthodontics, or tooth development) were collected. The test data set included the latest DPR of each subject (746 images) and the other DPRs (2014 images) were used for model training. A modified VGG16 model with two fully connected layers was applied for human identification. The proposed model was evaluated with rank-1, -3, and -5 accuracies, running time, and gradient-weighted class activation mapping (Grad-CAM)-applied images. Results: This model had rank-1, -3, and -5 accuracies of 82.84%, 89.14%, and 92.23%, respectively. All rank-1 accuracy values of the proposed model were above 80% regardless of changes in image characteristics. The average running time to train the proposed model was 60.9 s per epoch, and the prediction time for 746 test DPRs was short (3.2 s/image). The Grad-CAM technique verified that the model automatically identified humans by focusing on identifiable dental information. Conclusion: The proposed model showed good performance in fully automatic human identification despite differing image characteristics of DPRs acquired from the same patients. Our model is expected to assist in the fast and accurate identification by experts by comparing large amounts of images and proposing identification candidates at high speed.

Published: November 2021

El gato montés, Lynx rufus, es una de las seis especies de felinos silvestres que habitan en México. Se distribuye desde el nivel del mar hasta los 3,600 m, ocupando una gran variedad de hábitats entre los que se encuentran los desiertos, ecosistemas de montaña y humedales. Sin embargo, a la fecha, no existe información ecológica de la especie en humedales costeros. El objetivo general de este trabajo es proveer la primera información ecológica obtenida de forma sistemática sobre el gato montés en la Planicie Costera de Nayarit (PCN). Evaluamos su presencia histórica y actual, su abundancia relativa y patrones de actividad. Determinamos la presencia histórica del gato montés en la PCN mediante una búsqueda en bases de datos electrónicas utilizando las palabras: “Lynx”, “rufus”, “lince”, “bobcat” y “Nayarit”. Implementamos el protocolo del Censo Nacional del Jaguar usando cámaras trampa en un área de 72 km2 para documentar la presencia, distribución, abundancia relativa y patrones de actividad del gato montés. A través de la búsqueda en bases de datos encontramos 23 registros de gato montés en un área de al menos 3,000 km2 de la PCN. A partir de nuestro trabajo de campo obtuvimos 30 registros independientes con una abundancia relativa de 1.28 fotografías de gato montés / 100 días cámara. Documentamos la presencia de al menos 10 individuos diferentes, incluyendo adultos de ambos sexos y una hembra presuntamente embarazada. Su actividad es nocturna; 40 % de los registros ocurrieron entre las 00:00-06:00 hr. El gato montés habita los ecosistemas costeros de Nayarit. Los valores elevados de abundancia relativa sugieren una población estable en la PCN con respecto a lo que ha sido reportada en hábitat ideales para la especie tales como los matorrales y bosques templados. Su actividad nocturna coincide con lo que reportan otros trabajos para la especie. Aunque, en general, el gato montés se adapta bien al disturbio generado por actividades humanas, los impactos que estas tienen sobre sus poblaciones en los humedales costeros aún se desconocen. Para asegurar la permanencia de sus poblaciones es necesario realizar futuros estudios sobre su dieta, reproducción, ámbito hogareño y conectividad genética de la especie en los ecosistemas costeros del occidente de México.

Published: November 2021

Lasiurus arequipae fue descrita recientemente en el departamento de Arequipa como especie nueva y endémica para Perú, con distribución geográfica poco conocida. Se reporta la especie en Lomas de Sama Grande, departamento de Tacna, Perú. El espécimen fue recolectado durante un estudio sobre la fauna local de murciélagos, identificado con la clave taxonómica de Málaga et al. (2020), y comparado con el holotipo y paratipos depositados en la Colección Científica del Museo de Historia Natural de la Universidad Nacional de San Agustín, Arequipa, Perú. Se trata de una hembra, adulto, conservado como piel, cráneo y esqueleto (sin limpiar). Además, se presenta un mapa de distribución actual de la especie y contribuciones sobre su ecología. Destaca la observación de un refugio potencial asociado con el árbol de olivo. Este nuevo registro se ubica a 287 km al suroeste de la localidad de Huatiapa, que es el sitio más cercano de registro en donde se llevó a cabo el primer estudio en el departamento de Arequipa. Este hallazgo eleva a 11 las especies de murciélagos para el departamento de Tacna. Se sugieren esfuerzos de muestreo con métodos complementarios para generar un mayor conocimiento de la historia natural y ecología de esta especie, y establecer acciones de conservación.
Brief characterization of the behavior of the spiny rat Trinomys setosus (Rodentia: Echimyidae) in captivity
Authors: Bueno Flávia Regina , Spinelli de Oliveira Elisabeth , Klein Wilfried 
Published: November 2021

Las ratas espinosas del Atlántico (Trinomys setosus, Echimyidae) son roedores caviomorfos neotropicales pertenecientes a un grupo ecológicamente diverso, muy desconocido desde el punto de vista comportamental. El aseo se considera frecuente en Rodentia, siendo estimado que tanto los roedores silvestres como los de laboratorio emplean de 15 a 50 % de su tiempo de vigilia con esta tarea. De esta forma, nos preguntamos si el comportamiento de aseo en T. setosus es similar a aquel observado en especies estrechamente relacionadas, y caracterizamos en detalle las principales categorías de comportamiento observadas en la especie. La ocurrencia de aseo personal (lavado de cara, lavado de cuerpo, lavado de la región pélvica y rascado) fue cuantificada durante sesiones únicas de 30 minutos en 16 individuos adultos (cuatro machos y doce hembras), en el contexto de actividad, reposo y categorías de mantenimiento (defecación y micción). Se identificaron las siguientes categorías de comportamiento: 1) actividad locomotora, 2) permanecer inmóvil, 3) defecar, 4) lavarse la cara, 5) lavarse el cuerpo, 6) lavarse la región pélvica, 7) rascarse, 8) orinar, 9) sacudirse, 10) vocalizar. El comportamiento de aseo siguió las descripciones estereotipadas para otras especies de roedores y su ocurrencia representó el 6.7 % (hembras) y el 5.9 % (machos) del tiempo estudiado. El aseo, visto en una gran variedad de taxones animales, involucra numerosas funciones además del propósito principal del cuidado del cuerpo, que son de gran importancia para el bienestar animal. En comparación con los roedores comúnmente estudiados, como ratas, ratones, hámsteres y conejillos de indias, T. setosus destina relativamente poco tiempo al comportamiento de aseo, de forma comparable a su especie hermana T. yonenagae

El estudio de anormalidades dentales en mustélidos ha permitido identificar y describir patologías de especímenes distribuidos en diferentes hábitats y continentes. Estos análisis han sido implementados en cráneos de animales muertos. A través de un monitoreo no invasivo, se detectó a un mustélido neotropical in situ con una anormalidad dental, esa característica fue aprovechada para obtener información ecológica de la especie. Se analizaron registros de cámara trampa de un cabeza de viejo (Eira barbara) en vida libre en el sur de Brasil, el cual presentaba un canino superior izquierdo sobre-desarrollado, esta característica permitió identificarlo individualmente y recapturarlo. Mediante la estimación de densidad de Kernel se calculó el tamaño de su ámbito hogareño. Se revisaron cráneos de la especie en busca de anormalidades dentales. El espécimen fue recapturado en 5 estaciones de foto-muestreo dentro del Floresta Nacional de São Francisco de Paula (FLONA-SFP) en 11 ocasiones diferentes, durante un periodo de 7 meses (Marzo a Septiembre de 2012), el tamaño de su ámbito hogareño fue de 4.79 km2. Se encontraron diferencias en la cantidad de molares en dos mandíbulas de los cinco cráneos revisados. Aparentemente el canino anormal no ha interferido en la alimentación del espécimen, ya que ha alcanzado la adultez. El cabeza de viejo podría ocupar un área fuera de nuestro polígono de estudio dentro de la FLONA-SFP, por lo cual el tamaño de su ámbito hogareño podría ser más grande de lo que se reporta.

Aims Studies on long-term patient-reported outcomes after open surgery for triangular fibrocartilage complex (TFCC) are scarce. Surgeons and patients would benefit from self-reported outcome data on pain, function, complications, and satisfaction after this surgery to enhance shared decision-making. The aim of this study is to determine the long-term outcome of adults who had open surgery for the TFCC. Methods A prospective cohort study that included patients with open surgery for the TFCC between December 2011 and September 2015. In September 2020, we sent these patients an additional follow-up questionnaire, including the Patient-Rated Wrist Evaluation (PRWE), to score satisfaction, complications, pain, and function. Results A total of 113 patients were included in the analysis. At ≥ 60 months after an open TFCC reinsertion, we found a mean PRWE total score of 19 (SD 21), a mean PRWE pain score of 11 (SD 11), and a PRWE function score of 9 (SD 10). The percentage of patients obtaining minimum clinically important difference rose from 77% at 12 months to 83% at more than 60 months (p < 0.001). Patients reported fewer complications than surgeons, and overall complication rate was low. Conclusion Outcomes of patient-reported pain, function scores, and satisfaction are improved five years after open surgery for the TFCC. Cite this article: Bone Jt Open 2021;2(11):981–987.

Diabetes can cause some diseases or abnormalities. One of the disorders caused by diabetes may be erectile dysfunction (ED). ED is sexual dysfunction characterized by the inability to establish or maintain an erect penis during sexual activity and is a complication of men with chronic type 2 diabetes. These processes, disorders and diseases are highly influenced by the genetics of individuals. In this study, the relationship between genes and diabetes and ED has been explored by a system biology approach. For this purpose, the samples from ten control and diabetic-ED rats were collected. After a search in Gene Expression Omnibus (GEO), series with accession number GSE2457 comprising of 5 normal and 5 diabetic-ED rats were selected. Raw CEL files of these samples were normalized with robust multi-array average (RMA) expression measure method by using the linear models for microarray data (LIMMA) R package. The extracted probe IDs were transformed into 10451 unique and validated official gene symbols. Then, differentially expressed genes (DEGs) were identified between control and normal mucosa by employing the LIMMA R package. DEGs were classified by utilizing KEGG to underlying pathways by Enrichr. The expression values of DEGs were used to construct a gene regulatory network (GRN), by the GENEI3 R package. To analyze the topology of constructed GRNs, betweenness centrality was calculated. Genes with higher betweenness centrality scores were then identified, through the CytoNCA. We then took the commonality of DEGs genes and high-top ranking genes from CytoNCA via a predicted interaction network using GeneMANIA as the most likely important genes in erectile dysfunction. Among the 374 DEGs studied, 146 DEGs showed up-regulation and 228 DEGs displayed down-regulation expression in diabetic-ED rats. According to the Volcano plot, the dpp4, LOC102553868, Ndufa412, Oxct1, Atp2b3 and Zfp91 gene down-regulated and Lpl, Retsat, B4galt1 and Pdk4 genes up-regulated in ED and diabetic rats. Furthermore, genes like dpp4 acted as hubs in the inferred GRN.
Foreign language peace of mind: a positive emotion drawn from the Chinese EFL learning context

Published: November 2021

AbstractThis study presents a new positive emotion construct, 外语平和心态 (waiyu pinghe xintai) or Foreign Language Peace of Mind (FLPOM), drawn from the Chinese cultural tradition. It is a low-arousal positive (LAP) emotional state (e.g., calmness, peacefulness) and a state of internal harmony. Three sub-studies were conducted. In Study 1, a measurement scale of FLPOM was developed and validated. In Study 2, the FLPOM scale was administered to Chinese English as a Foreign Language learners along the Chinese Foreign Language Enjoyment (FLE) scale which can potentially reflect slightly more high-arousal positive (HAP) states (e.g., joy, enthusiasm) to test the discriminability of FLPOM from FLE. Study 3 examined the extents to which FLPOM and FLE predict Chinese learners’ language proficiency. Correlation and discriminant validity analysis confirmed that FLPOM and FLE were related but discriminable emotion constructs. Stepwise regression analyses revealed that FLPOM was a stronger predictor of Chinese learners’ self-perceived FL proficiency than FLE. Possible implications on FL teaching and learning in the Chinese context were provided.
Wigalois am Rande des Paradieses
Authors: Mierke Gesine , Schanze Christoph 
Published: November 2021

Abstract
This essay deals with the illustrated Leiden codex of Wirnt von Grafenberg’s Arthurian novel ›Wigalois‹ (Leiden, University Library, Ltk 537). We will show that, in the interplay of text and picture, the codex is meant to privilege a certain interpretation of the novel text, which is a salvatory reading of ›Wigalois‹. We base our examination on the two illustrated pages opening the codex, which shape the visual language of the entire illustration cycle. In addition, this illustration cycle has the function of further emphasising some of the novel’s central scenes and clarifying their potential of meaning. The last illustrated page of the codex integrates the Dukes of Braunschweig-Grubenhagen as patrons of the manuscript into the illustration programme, and provides a back reference ranging from the history of salvation to world history as well as local history.

Published: November 2021

Abstract
Scaling up stirred tanks is a significant challenge because of the research gaps between laboratory and industrial-scale setups. It is necessary to understand the effects of scale-up on the mass transfer in stirred tanks, and this requires meticulous experimental analysis. The present study investigates the effects of tank size and aspect ratio (

) on the volumetric mass transfer coefficients of shear-thinning fluids. The experiments were conducted in three stirred tanks of different sizes (laboratory and pilot scale) and geometries (standard and nonstandard).

H

of 1. Impeller stirring speeds and gas flow rates were in the range of 800–900 rev min−1 and 8–10 L min−1, respectively. The volumetric mass transfer coefficient was estimated based on the dissolved oxygen concentration in the fluids, and the effects of rheology and operating conditions on the volumetric mass transfer coefficient were observed. The volumetric mass transfer coefficient decreased as tank size increased and increased with an increase in operating conditions, but these effects were also clearly influenced by fluid rheology. The impacts of scale-up and operating conditions on the volumetric mass transfer coefficient decreased as liquid viscosity increased.
New Mainstream Films and Television Dramas in China: The Construction of Industrial Aesthetics and Consumption of Youth Culture
Authors: Chen Xuguang 
Published: November 2021

Abstract
As a significant industrial and cultural phenomenon, the rise of new mainstream films and TV dramas in China embodies the inclusion of multiple cultures (mainstream culture, grassroot culture, youth culture, etc.) and the respect for diverse audiences. In particular, such trends bring into focus the youth market and explore the image-based expression of youth culture, subculture and fashion culture. However, this author argues that the production of such films and TV dramas also needs to further pursue market-orientated strategies, sustainable development, and conformity to industrial standards. In short, the production of new mainstream films and TV dramas should not revert to the previous production pattern of mainstream films.

Published: November 2021

Purpose. Apply statistical analysis to the volumetric samples of electricity consumption parameters to reduce the amount of network node capacity that will be stored.
Methodology. Using the statistical data methods processing in the graphical programming system LabVIEW.
Findings. Electricity is one of the energy types, the generation volume, transportation, distribution and use of which is constantly growing. At all these stages, the control of the change rate parameters of electrical energy – power occurs. Power is characterized by certain parameters that are subject to continuous monitoring. The change capacity in the conditions of industrial enterprises has a complex character with certain stochastic components. The need to record detailed information causes an increase in the data amount to be stored. As a result, there is a processing data problem on electric energy volumes and electric power parameters with reduction data volume and informativeness preservation. Based on the statistical normal distribution concept, in the graphical programming environment the data processing subsystem on sampling intervals of active and reactive powers of low voltage section the step-down substation is constructed. Using the indicators of the characteristics of the normal distribution of active and reactive power, the analysis of their semi-daily samples was performed. Selected intervals at which the indicators of normal distribution differ significantly, which allowed to form conclusions about the presence of modes close to idling Originality. It is established that due to the difficulty covering long time periods under the fixing condition data on electric power parameters, there is a dilemma regarding the resulting information amount and its detailing, to avoid information loss, a procedure based on the law of normal data sampling is the resulting data to be stored, with the possibility recording significant deviations in terms of excess and sample asymmetry.
Practical value. Applying the proposed method in the monitoring system for long-term monitoring electrical power parameters, it is possible to reduce significantly the amount of data during the transmission basic information, power level and range, and, if necessary, use additional information about changes in observation intervals expressed through excess and asymmetry.
