BACKGROUND Orthopaedic surgical education has traditionally depended on the apprenticeship model of“see one,do one,teach one”.However,reduced operative exposure,stricter work-hour regulations,medicolegal constraints,and patient safety concerns have constrained its practicality.Simulation-based training has become a reliable,safe,and cost-efficient alternative.Dry lab techniques,especially virtual and augmented reality,make up 78%of current dry lab research,whereas wet labs still set the standard for anatomical realism.AIM To evaluate the effectiveness,limitations,and future directions of wet and dry lab simulation in orthopaedic training.METHODS A scoping review was carried out across four databases-PubMed,Cochrane Library,Web of Science,and EBSCOhost-up to 2025.Medical Subject Headings included:"Orthopaedic Education","Wet Lab","Dry Lab","Simulation Training","Virtual Reality",and"Surgical Procedure".Eligible studies focused on orthopaedic or spinal surgical education,employed wet or dry lab techniques,and assessed training effectiveness.Exclusion criteria consisted of non-English publications,abstracts only,non-orthopaedic research,and studies unrelated to simulation.Two reviewers independently screened titles,abstracts,and full texts,resolving discrepancies with a third reviewer.RESULTS From 1851 records,101 studies met inclusion:78 on dry labs,7 on wet labs,4 on both.Virtual reality(VR)simulations were most common,with AI increasingly used for feedback and assessment.Cadaveric training remains the gold standard for accuracy and tactile feedback,while dry labs-especially VR-offer scalability,lower cost(40%-60%savings in five studies),and accessibility for novices.Senior residents prefer wet labs for complex tasks;juniors favour dry labs for basics.Challenges include limited transferability data,lack of standard outcome metrics,and ethical concerns about cadaver use and AI assessment.CONCLUSION Wet and dry labs each have unique strengths in orthopaedic training.A hybrid approach combining both,supported by standardised assessments and outcome studies,is most effective.Future efforts should aim for uniform reporting,integrating new technologies,and policy support for hybrid curricula to enhance skills and patient care. 展开更多

With the rapid development of China's agricultural production and the improvement of people's living standards and health awareness,people's demands for food quality and nutrition have become increasingly strong. Agricultural products that meet various functional needs such as nutrition,health care and safety are increasingly favored by the general public. Se,one of the trace elements necessary for the human body,has begun to be applied and developed in medicine and other life sciences. Developing Se-enriched agricultural relying on Guangxi's unique Se-enriched soil resources is of great significance to enhance people's quality of life,increase the added value of agricultural products,and promote the transformation and upgrading of modern agriculture in the region. Starting with the development status and advantages of industrial development of Se-enriched agriculture in Guangxi,the main problems existing in the current industrial development of Se-enriched agriculture in Guangxi were summarized,and specific countermeasures were put forward in this paper,so as to provide theoretical support for the development of Se-enriched agriculture in Guangxi. 展开更多

This study was conducted to investigate the effect of Se-enriched lactobacillus on antibody of Newcastle Disease Virus(NDV)of broilers.One thousand day-old AA broiler chickens were selected from a chicken farm of Jinghai County,and the chickens were divided randomly into two groups,which respectively had five repeat groups with 100 chickens each,one named basal diet group,and the other named Se-enriched lactobacillus group.Corn soybean meal diet was selected for basal diet group,while 2%se-enriched lactobacillus was added into corn soybean meal diet for the other group.The method of feeding was free diet,drinking,and routine immunization program was adopted.This test period was 42 d.Two chickens were selected randomly in each repeat for slaughtering and collecting serums on the 14th,28th and 42nd d.Assessments on the effect of Se-enriched lactobacillus in antibody titer of NDV of broilers were made by hemagglutination-inhibition test.The results indicated that antibody titer of NDV was increased significantly by Se-enriched lactobacillus. 展开更多

The Literary Lab at Stanford University is one of the birthplaces of digital humanities and has maintained significant influence in this field over the years.Professor Hui Haifeng has been engaged in research on digital humanities and computational criticism in recent years.During his visiting scholarship at Stanford University,he participated in the activities of the Literary Lab.Taking this opportunity,he interviewed Professor Mark Algee-Hewitt,the director of the Literary Lab,discussing important topics such as the current state and reception of DH(digital humanities)in the English Department,the operations of the Literary Lab,and the landscape of computational criticism.Mark Algee-Hewitt's research focuses on the eighteenth and early nineteenth centuries in England and Germany and seeks to combine literary criticism with digital and quantitative analyses of literary texts.In particular,he is interested in the history of aesthetic theory and the development and transmission of aesthetic and philosophical concepts during the Enlightenment and Romantic periods.He is also interested in the relationship between aesthetic theory and the poetry of the long eighteenth century.Although his primary background is English literature,he also has a degree in computer science.He believes that the influence of digital humanities within the humanities disciplines is growing increasingly significant.This impact is evident in both the attraction and assistance it offers to students,as well as in the new interpretations it brings to traditional literary studies.He argues that the key to effectively integrating digital humanities into the English Department is to focus on literary research questions,exploring how digital tools can raise new questions or provide new insights into traditional research. 展开更多

Mastitis is an inflammatory infection of the mammary glands that is frequently observed in animals. The aim of this study was to determine the prevalence of this infection, identify the pathogens responsible and highlight the risk factors in the region of Labé (Republic of Guinea). The survey involved 96 farmers in three prefectures (Koubia, Labé, Lélouma) and covered 3,199 animals, including 611 lactating females. The clinical survey revealed 49 suspected cases of mastitis, mainly in goats. The analysis showed a prevalence of clinical mastitis of 2.95% and a mortality rate of 18.35%. The identified risk factors were the hygiene of the premises, the age of the females, husbandry practices and the lack of regular veterinary care. 展开更多

Climate crises necessitate adaptive,cost-effective,and community-driven strategies to enhance urban resilience.Tactical urban design,which includes temporary and experimental interventions,is becoming increasingly vital,particularly in indigenous contexts.This study explores the spatial agency approach within tactical urbanism,emphasizing low-technology techniques,indigenous knowledge,and decentralized design as active elements in transforming public spaces.It aims to review recent trends and alternative tactical strategies in indigenous settings while identifying the attributes and mechanisms that contribute to the creation of sustainable public spaces through spatial agency.Employing an interpretive qualitative methodology that includes case studies and content analysis,the research focuses on the Open-Air Lab in Dakar,Senegal(Codesign Lab,Paolo Cascone).This project,a small-scale public infrastructure initiative born from participatory design,exemplifies a hybrid model that combines traditional craftsmanship,low-tech digital fabrication,and environmentally conscious solutions.The findings indicate that framing spatial agency as an actor-network process brings marginalized actors and practices to the forefront,fostering empowerment,social synergy,and climate-responsive design.The study advocates for a shift in tactical urban design from ephemeral placemaking toward long-term,adaptive strategies grounded in local materiality,community engagement,knowledge systems,and decentralized networks.These insights reshape the understanding of urban adaptability and provide practical guidance for architects and planners aiming to create inclusive,climate-resilient public spaces in indigenous and Global South contexts. 展开更多
