The use of biological control agents such as entomopathogenic fungi is an alternative for the control of kale(Brassica oleracea L.) defoliating caterpillars. The objective was to investigate the efficacy of entomopathogenicfungi of Amazon region in the control of defoliating caterpillars in kale and their impacts on the physiologicaland agronomic responses of the crop. Field and greenhouse experiments were conducted in randomized blockdesign and completely randomized design, respectively. The treatments consisted in the application of isolatesof entomopathogenic fungi: Beauveria bassiana, Isaria sp., Metarhizium anisopliae and Trichoderma asperellum.The control treatment consisted of the application of an chemical insecticide based on deltamethrin.Variablesreferring to the development, yield and physiology of the plants were evaluated. Field results revealed thatplants treated with the fungi B. bassiana, M. anisopliae and T. asperellum showed levels of severity, number ofleaves and commercial yield that did not differ from the standard treatment; however, they showed a lowerpopulation density of the defoliating caterpillar complex. The application of the treatments with M. anisopliaeand chemical insecticide showed better photosynthetic performance. In greenhouse, the fungus T. asperellumprovided greater plant height and robustness index in relation to the treatment with chemical insecticide.The entomopathogenic fungi of Amazon region can be contributed to the integrated management of leafdefoliating caterpillars in kale. These microorganisms have similar efficiency with chemical insecticides, beingecologically and economically viable to mitigate the negative impacts caused by the systematic use ofchemicals.

Uma problematização da emergência das Metodologias do Ensino de Ciências Naturais no Brasil
Authors: Rigue Fernanda Monteiro , Corrêa Guilherme Carlos
Published: August 2023

Busca-se, por meio de uma perspectiva genealógica, traçar algumas linhas que permitam compreender as forças que concorreram para o estabelecimento da perspectiva majoritária, estabelecida nas décadas de 1980 e 1990, que orienta a disciplina de Metodologia do Ensino de Ciências Naturais nos currículos de formação inicial de professores/as no Brasil. A partir da importante influência de Paulo Freire, Dermeval Saviani e Demétrio Delizoicov, mobiliza-se a atenção para as condições de possibilidades que tornaram possível a consolidação das Metodologias do Ensino de Ciências Naturais. O entrelaçamento dessas forças apresenta o potencial de cultivar estratégias educacionais com estudantes de licenciatura, em detrimento da aplicação, com tintes protocolares, de uma sequência de procedimentos didáticos garantidora da transposição didática dos conteúdos científicos historicamente acumulados pela humanidade, atrelados ao duplo ensino-aprendizagem tão bem acomodados nas garantias da escolarização.
Motivating Students Intrinsically Through ESP and Integration of Academic and Professional Skills in EMI Context
Authors: Khan Rana
Published: August 2023

While much research has been done on improving motivational levels among students, educators still struggle everyday trying to motivate students. There’s little or negligible evidence of research pointing to the role of ESP and integrated academic and communicative skills in improving intrinsic motivational levels among students. This report discusses a case study in a higher educational institute, in Kuwait where the low motivational levels in students encouraged the foundation program unit to explore whether incorporating ESP and academic skills in the foundation program can motivate students intrinsically to learn the language and thus support them in acquiring content in their diploma programs. The foundation unit designed a new foundation course, ESF (English and Skills Foundation) program to deal with amotivation and motivate students intrinsically. The new program aimed at aligning future goals of students to their current language learning in order to motivate them intrinsically under the EMI context. The program introduced two new components ESAP (English for Specific and Academic Purposes), Business English and IDEAS (Integrated Directions for English and Academic Skills), a course aimed at improving academic, communicative and computer literacy skills in students to prepare them for the globalized environment and learning they need so much in their EMI context. Closed ended questionnaires and open-ended focus group interviews were administered to foundation program students, both before and after the implementation of the program, to investigate any improvement in their motivational levels. The findings indicate that program was taken positively by students and showed improved motivational levels amongst students. The research findings revealed a new dimension wherein students employed learner strategies and integrated regulation pointing to improved intrinsic motivational levels as a result of the new ESF program. The new ESF program sets an example as a pilot project for other major programs of study.

Published: August 2023

The aim of this study is to explore a novel classification and investigate the clinical significance of hepatocellular carcinoma (HCC) cells. We analyzed integrated single-cell RNA sequencing and bulk RNA-seq data obtained from HCC samples. Cell trajectory analysis divided HCC cells into three subgroups with different differentiation states: state 1 was closely related to phosphoric ester hydrolase activity, state 2 was involved in eukaryotic initiation factor 4E binding, translation regulator activity and ribosome, and state 3 was associated with oxidoreductase activity and metabolism. Three molecular classes based on HCC differentiation-related genes (HDRGs) from HCC samples were identified, which revealed immune checkpoint gene expression and overall survival (OS) of HCC patients. Moreover, a prognostic risk scoring (RS) model was generated based on eight HDRGs, and the results showed that the OS of the high-risk group was worse than that of the low-risk group. Further, potential therapeutic drugs were screened out based on eight prognostic RS-HDRGs. This study highlights the importance of HCC cell differentiation in immunotherapy, clinical prognosis, and potential molecular-targeted drugs for HCC patients, and proposes a direction for the development of individualized treatments for HCC.
Study on the cytokines related to SARS-Cov-2 in testicular cells and the interaction network between cells based on scRNA-seq data
Authors: Yu Fan , He Haihong , Huang Tingting , Zhou Yiwen
Published: August 2023

Inflammatory cytokine storms (CS) in COVID-19 patients are associated with elevated levels of 13 specific cytokines, potentially impacting male fertility by causing testicular cell damage and disrupting the immune microenvironment. Some patients present with scrotal discomfort and orchitis. However, few studies have explored cytokine expression in testicular cells and their role in cell-to-cell communication. In this study, we integrated single-cell sequencing data sets of testicular cells, annotating 20 cell clusters using marker genes and the Human Cell Landscape database. We constructed cell pseudo-chronological trajectories, hub genes, and analyzed the cytokine interaction network between sperm cells using CellChat. Our findings identified 12 types of testicular cells, with four cytokines (IL8, CCL2, CCL3, and TNF) potentially involved in immune processes. Pseudo-chronological trajectory analysis indicated IL8 and CCL3's essential roles in testicular macrophages and endothelial cell development, affecting the immune microenvironment. We determined eight key cytokines (IL1, IL2, IL4, IL6, CCL, CSF3, TNF, and IFN-II) functions in cell interaction networks. Network analysis of exogenous cytokines directly acting on testicular cells showed IL2 potentially affecting all testicular cells, suggesting a vital role in cell communication. This research offers valuable insights into CSs effects on testicular cells and their potential impact on male fertility during COVID-19 infection.

In accordance with the inability of various hair artefacts subjected to dermoscopic medical images, undergoing illumination challenges that include chest-Xray featuring conditions of imaging acquisi-tion situations built with clinical segmentation. The study proposed a novel deep-convolutional neural network (CNN)-integrated methodology for applying medical image segmentation upon chest-Xray and dermoscopic clinical images. The study develops a novel technique of segmenting medical images merged with CNNs with an architectural comparison that incorporates neural networks of U-net and fully convolutional networks (FCN) schemas with loss functions associated with Jaccard distance and Binary-cross entropy under optimised stochastic gradient descent + Nesterov practices. Digital image over clinical approach significantly built the diagnosis and determination of the best treatment for a patient’s condition. Even though medical digital images are subjected to varied components clarified with the effect of noise, quality, disturbance, and precision depending on the enhanced version of images segmented with the optimised process. Ultimately, the threshold technique has been employed for the output reached under the pre- and post-processing stages to contrast the image technically being developed. The data source applied is well-known in PH2 Database for Melanoma lesion segmentation and chest X-ray images since it has variations in hair artefacts and illumination. Experiment outcomes outperform other U-net and FCN architectures of CNNs. The predictions produced from the model on test images were post-processed using the threshold technique to remove the blurry boundaries around the predicted lesions. Experimental results proved that the present model has better efficiency than the existing one, such as U-net and FCN, based on the image segmented in terms of sensitivity = 0.9913, accuracy = 0.9883, and dice coefficient = 0.0246.

Published: August 2023

This meta-analysis investigated the effect of physical exercise (PE) on the levels of oxidative biomarkers in randomized controlled trials (RCTs) involving healthy subjects. We searched five databases for articles until May 1, 2023. A random-effect meta-analysis, subgroup analysis, meta-regressions as well as trim and fill method were conducted using STATA 11.0, involving ten articles. According to the results of the meta-analysis, PE had no significant effect on superoxide dismutase (SOD), glutathione peroxidase, and catalase levels. PE induced significant increase in total antioxidant status (standardized mean difference [SMD] 1.53, 95% CI 0.73–2.32), and PE could significantly reduce the level of malondialdehyde (MDA) (SMD −1.11, 95% CI −2.15 to −0.06). Sensitivity analyses and subgroup analyses showed that male participants, body mass index (BMI) <25, exercise duration between 1 and 12 weeks, resistance exercise or multicomponent exercise, and exercise of low or moderate intensity were associated with a significant PE-induced decrease in MDA concentrations. Meta-regression analysis identified the age of the participants as a confounder of the effect of PE on SOD levels. The older age of the subjects was associated in a gradient fashion with incident SOD levels. Further RCTs are required to investigate the optimal PE protocol for people of different ages and BMI as well as the effect of PE on oxidative stress.
Coordination and referential dependencies: a dependency grammar account in terms of predicate-valent structures
Authors: Osborne Timothy , Li Jiaxin
Published: August 2023

The present paper explores the nexus of coordination and referential dependencies, focusing on sentences such as ‘Max and Lucie talked about him’, in which it is hardly possible forMaxandhimto be co-valued. Previous accounts claim that such referential dependencies are in fact possible on a collective reading. It will be demonstrated here, however, that informants consistently judge the co-valued reading in such cases to be either strongly marginal or unavailable, regardless of whether a collective or distributive reading obtains. It is claimed that the manner in which referential dependencies interact with coordinate structures can be addressed insightfully in terms of ‘predicate-valent’ structures (as opposed to ‘predicate-argument structures’). A constraint in this regard will be proposed: the ‘Conjunct Referential Dependency Constraint’ (CRDC). The CRDC is couched in a Dependency Grammar (DG) approach to syntax.
Promoting ELF awareness in Language Teacher Education and ELT practices: perspectives and challenges
Authors: Vettorel Paola , Antonello Monica
Published: August 2023

Research into the pedagogical implications of English as a Lingua Franca (ELF) has seen important developments over the last decade, through investigation of how English Language Teaching (ELT) can, and should, respond to the challenges and issues connected to the global spread of English in terms of curricula, syllabi, materials and classroom practices. In this perspective, Language Teacher Education is a central factor to promote awareness of the necessity to respond to how English is used as a global lingua franca today, not least in terms of Language Awareness, multilingual practices and meaning negotiation through Communication Strategies. In this paper we aim at addressing aspects related to teacher awareness as to ELF, in terms of how ‘language’, ‘language teaching and learning’ and ‘language use’ are conceived within an ELF-aware perspective. We will look in particular at the role that Language Awareness, Communicative Competence especially as to its strategic dimension in pragmatic moves, and multilingual practices play in ELF, and at their relevance in raising teachers’ awareness of ELF and ELF-aware pedagogic practices. We will then examine how these aspects interrelate with the three components in Sifakis’ ELF awareness model – awareness of language and language use, awareness of instructional practices, awareness of learning – also providing exemplifications of activities that could be used in ELF-oriented Teacher Education, and in ELT practices, to foster reflection on how they can become part of English language teaching and learning.
Examining ELF-aware teaching and learning: action research as a tool for ELF research and teacher education
Authors: Heike Christie
Published: August 2023

This paper examines the role that action research – including both academic studies and action research undertaken by teachers for the purposes of professional development – might play in helping to close the existing gap between the pedagogical implications of English as a Lingua Franca (ELF) research and the practical implementation of an ELF-oriented approach in the classroom. It is argued that the purposes and characteristic features of action research as a research methodology are particularly relevant and fitting to address the kinds of questions relating to pedagogy which remain at this stage of ELF research. To support this thesis, the heart of the paper presents findings from an applied linguistic study investigating the implementation of an ELF-oriented approach in a university-level pilot course in order to illustrate the kinds of insights which classroom-based action research studies can provide. Finally, the concluding section reflects on the role of action research as a part of teachers’ professional development, the potential contributions which such research might make to ELF research and the need for the wider ELF research community to pay more attention to findings from action research undertaken as part of teacher education programs.
Analysis of alternate material Onyx™ for total knee arthroplasty instrumentation sets
Authors: Gregg Nathan , Kendrick Alyssa M. , Carter Jill M. , Gittins Mark E. , MacNeill Sarah C.
Published: August 2023

Context

A 25-pound weight limit is currently set on containerized instrumentation sets by the Association of periOperative Registered Nurses (AORN) and the Association for the Advancement of Medical Instrumentation (AAMI), in order to reduce strain on the staff and ensure that the sets are not too crowded in order to preserve sterilization and drying of the instruments. This is pushing companies to reduce the weight and number of instrumentation sets for the operating room. One solution has been to explore the viability of new, lighter materials such as Onyx.

Objectives

The goal of this study is to evaluate the novel material Onyx as a viable material utilized in reusable total knee arthroplasty (TKA) instrumentation sets utilizing traditional steam sterilization as the sterilization method.

Methods

Mechanical and biocompatibility tests according to the American Society for Testing Materials (ASTM) and International Organization for Standardization (ISO) 10,993 were run to evaluate the Onyx Material to see if it would be a viable alternative to the stainless and martensitic steel that is currently being utilized.

Results

Gross warping and cracking after 10 rounds of sterilization was observed. This was qualitatively worse in the Onyx without a carbon fiber component. The Onyx material did not meet biocompatibility standards for its application.

Conclusions

Onyx was determined to not be a viable material for TKA instruments regarding multiple high-pressure and -temperature sterilizations and cytotoxic cell testing.

Published: August 2023

Along with the increase in demand for electricity, dependability requirements for the power supply system also increase. Transformers are the backbone of the electrical system; thus, they must function reliably and safely. In this study, a method based on Fourier-transform infrared spectroscopy technology is proposed for assessing the ageing level of insulating oils. Copper-catalysed thermal ageing is applied to four distinct insulating oils at a temperature of

. The insulating oil ageing peaks are promptly measured using infrared spectroscopy, and the peak area ratios are associated with the interfacial tension and dielectric loss factor. It is observed that the peak area ratio of the ageing peaks and interfacial tension are significantly correlated, and this relationship can be used to determine the ageing condition of the insulating oil. The findings of this study can be used to design sensors for online monitoring of insulating oil quality.
Mars and Mercury. A golden wolf from Western Poland – a mysterious find
Authors: Kontny Bartosz , Miśta-Jakubowska Ewelina A. , Żabiński Grzegorz
Published: August 2023

The paper discusses a mysterious zoomorphic wolf-shaped copper alloy artefact that was discovered as a stray find in Międzyrzecz (Poland). The find is bar-like with a profiled engraved image of a lying animal, possibly a wolf. It is locally gilded on the visible side of “wolf” details. The gilding was made using an amalgam technique known since Antiquity, with the base metal composed of arsenical copper alloy with lead addition. A fixing element made of iron has only survived fragmentarily, which renders the reconstruction of the entire artefact’s shape impossible. Its function has not been identified, but a broad spectrum of possible interpretations has been proposed. Stylistic traits allow to date the artefact to the Migration Period, or more specifically to the 6th century. The wolf image implies that the artefact can be related to the Germanic warriors’ world. At present, it cannot be determined whether there was a 6th century settlement cluster in the vicinity of Międzyrzecz to which the find can be related, or we are dealing with an isolated testimony of population translocations.
X’oyep’s Women: History, Memory, and Photography
Authors: Castillo Troncoso Alberto del
Published: August 2023

This article revisits one of the most iconic moments in the recent history of photojournalism in Mexico: the Zapatista uprising at Chiapas in 1994. Throughout the essay, the publication of Pedro Valtierra’s famous photograph of a group of women who bravely confronted the Mexican Army on January 3, 1998, which immediately obtained international recognition, is reviewed, followed by an analysis of the photographer’s work, as well as the historical context within which the images depicted are situated. Through the analysis of photographs, combined with the narrated experiences of the photojournalists who created them, I examine the development of new political identities, such as indigenous Zapatista women, as well as the changing roles of photographs and the media press during the last years of the twentieth century.

Published: August 2023

The cardiac endothelium influences ventricular chamber development by coordinating trabeculation and compaction. However, the endothelial‐specific molecular mechanisms mediating this coordination are not fully understood. Here, we identify the Sox7 transcription factor as a critical cue instructing cardiac endothelium identity during ventricular chamber development. Endothelial‐specific loss of Sox7 function in mice results in cardiac ventricular defects similar to non‐compaction cardiomyopathy, with a change in the proportions of trabecular and compact cardiomyocytes in the mutant hearts. This phenotype is paralleled by abnormal coronary artery formation. Loss of Sox7 function disrupts the transcriptional regulation of the Notch pathway and connexins 37 and 40, which govern coronary arterial specification. Upon Sox7 endothelial‐specific deletion, single‐nuclei transcriptomics analysis identifies the depletion of a subset of Sox9/Gpc3‐positive endocardial progenitor cells and an increase in erythro‐myeloid cell lineages. Fate mapping analysis reveals that a subset of Sox7‐null endothelial cells transdifferentiate into hematopoietic but not cardiomyocyte lineages. Our findings determine that Sox7 maintains cardiac endothelial cell identity, which is crucial to the cellular cross‐talk that drives ventricular compaction and coronary artery development.

Eugeniusz Chlebcewicz is undoubtedly one of the outstanding representatives of the period in which he lived. The biographical sketches of Jan Barszczewski (1790–1851), Franciszak Bahuszewicz (1840–1900), Janka Kupala (1882–1942) and Ciotka (1876–1916) have a documentary value. Chlebcewicz’s works are often referred to by contemporary literary critics who carry out research on new Belarusian literature. His relations with representatives of the literary period named “Парнасу Нашанiўскай праы” are testimony to the enormous role of Chlebcewicz himself in the revival of the Belarusian movement at the beginning of the 20th century.

Enriching the Lagos Model of Student Teaching with Pedagogical Provisions from the Columbia Model
Authors: Rufai Saheed Ahmad , Musa Bello
Published: August 2023

The achievements of teacher preparation models have been studied through the use of input-output models. While teacher education programmes are considered to be the input, student achievements are the output. Consequently, certain models have been found to be more effective and evaluated more than others. It is noted that of all the components that constitute teacher education programme, the student teaching has received less attention. This study evaluates the student teaching sub-components of the University of Lagos, Faculty of Education and the University of Columbia Teachers College, with a view to attempting an enrichment of the former with some of the best pedagogical provisions from the latter. With the use of an adopted instrument tagged Comprehensive School Reforms Classroom Observation System (CSRCOS) and other trainee records, the evaluation identifies strengths and weaknesses as well as best practices for enrichment purposes. Results reveal that there were disparities in Lagos teacher trainees’ scores by their Departments and over a period of three academic sessions. These disparities can be defined and explained by the mode and type of field experience that the student teachers were exposed to. The study underscores some of the Columbia pedagogical practices for systematic replication by the Lagos Model.

Introduction: Congenital malformations are the leading cause of early neonatal mortality and the second leading cause of infant mortality. Among them, congenital heart diseases are the main cause of mortality in the early neonatal period. Material and methods: A prospective cross-sectional study was conducted at the "Dr. Ovidio Aliaga Uría" Children's Hospital in La Paz, Bolivia, at an altitude of 3,650 masl. A pediatric cardiology outpatient clinic was set up to examine 42 children, recording clinical data, physical examination, and color Doppler echocardiography. Results: The most frequent reason for referral was a heart murmur. In 52.38% (n=22) of the evaluated patients, congenital heart disease was present, with ventricular septal defects being the most common at 40.91% (n=9), followed by atrial septal defects at 18.18% (n=4), persistent foramen ovale at 13.64% (n=3), and patent ductus arteriosus at 9.09% (n=2) of patients. Discussion: There are very few studies in populations living at altitudes above 3,000 masl. Our study shows a high percentage of children with cardiac defects, which may be attributed to accurate diagnosis at referral or possibly a higher incidence of cardiac malformations in the studied population. Conclusion: the most common cardiac defect was ventricular septal defect, as described in populations living at sea level.
Combined lumbar plexus sciatic nerve block for hip fracture: a case series with 442 patients
Authors: Karaca Prof. Dr. Saffet
Published: August 2023

Introduction: Hip fractures are a global health problem in the elderly population. The mortality and morbidity after anesthesia are high in the elderly population with hip fractures due to numerous comorbidities. In recent years, the combined lumbar sciatic block (CLSB) method is safely applied in high-risk hip fracture surgeries. This study aims to examine 442 cases of hip fracture surgery in our clinic. Method: 442 high-risk patients operated in Istanbul University Cerrahpasa, Cerrahpasa Faculty of Medicine, Department of Orthopedics and Traumatology between 2004 and 2016 are included in this retrospective study. Neurostimulation technique combined with lumbar plexus and sciatic nerve block applied in all cases. The Lumber plexus block consists of bupivacaine 15 cc 0.5 % and prilocaine 15 cc 2%. Sciatic nerve block consists of bupivacaine 10 cc 0.5 % and prilocaine 10 cc 2%. Cases are evaluated for anesthesia quality and complication rate. Results: There was no need for any sedation or analgesia in 199 cases. Sedation was required in 147 cases. In 82 cases, the need for sedation combined with analgesia occurred. The conversion to general anesthesia was required in 14 cases. Complication wise, the epidural spread was observed in 5 cases and 3 cases got convulsions. Conclusion: It is concluded that CLSB is a safe alternative technique to use in high-risk hip fracture surgery.
