Sertoli cells (SCs), the sole somatic cell type within seminiferous tubules, play essential roles in nutritional support, blood-testis barrier (BTB) formation, and hormonal regulation, indispensable for germ cell development in testes. However, primary cultured SCs are prone to undergo replicative senescence, which severely impedes their in-depth studies in vitro. In this study, we introduced the SV40 large T antigen into giant panda primary testicular somatic cells via lentiviral transduction and then performed monoclonal isolation, eventually successfully establishing two immortalized cell lines (PD-SCs-1 and PD-SCs-2). These two cell lines exhibited long-term proliferative capacity and have been cultured for more than eight months and passaged over 70 times. They also stably expressed typical SC markers and retained intercellular junction-like structures and molecular responses to hormonal stimulation, supporting the preservation of several important SC characteristics. Yet, immortalization was accompanied by alterations in cellular properties, including reduced androgen receptor expression and chromosomal abnormalities. Together, the established PD-SCs-1 and PD-SCs-2 cell lines provide a valuable in vitro platform for in-depth investigation of the testicular niche, the mechanisms for spermatogenesis, and the pathology of reproductive disorders in giant pandas, and also lay the experimental groundwork for development of novel breeding technology and conservation of this endangered species.</p>","PeriodicalId":7955,"journal":{"name":"Animals","volume":"16 19","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13663398/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, extended reality (XR) technologies have emerged as promising tools to enhance image-guided surgical procedures by improving three-dimensional anatomical understanding, surgical navigation, and intraoperative decision-making. Although XR has gained considerable attention in human surgery, its application in veterinary surgery remains at an early stage. This narrative review aimed to provide a comprehensive overview of the current evidence regarding XR technologies in small animal surgery, with particular emphasis on their integration with preoperative and intraoperative imaging modalities. The available literature was reviewed to evaluate current clinical applications, technological developments and future perspectives. A literature search was performed in PubMed, Scopus, and Web of Science for studies published up to May 2026 using combinations of terms related to extended reality and small animal veterinary surgery. Original articles, case reports, pilot studies, technical reports, and reviews addressing clinical, experimental, or simulation-based applications were considered. Although several studies have explored the use of XR technologies for veterinary education, anatomical training, and diagnostic imaging instruction, relatively few investigations have assessed their direct application in clinical surgical practice. Potential applications have been described in orthopedic, oncologic, neurologic, cardiovascular, and minimally invasive procedures. Crucially, the currently available peer-reviewed evidence is restricted to canine patients, as no eligible feline studies were identified. Current evidence suggests that XR is an emerging technology with potential applications in canine surgical planning, image-guided procedures, and surgical training.

To overcome these limitations, this study proposes an improved YOLO11-based pig behavior detection model, termed DWEC-YOLO, for recognizing normal behaviors (standing, lying, sitting, and feeding) and aggressive behaviors (fighting, ear biting, and tail biting). First, the C3k2-DySnake module is embedded within the backbone architecture, enabling more effective extraction of fine-grained visual details. Second, an EUCB-SC module is employed during feature aggregation and works jointly with the CoordAtt mechanism to strengthen multi-scale feature representations, thereby enhancing the network's sensitivity toward critical interaction areas. In addition, Wise-ShapeIoU is adopted as the bounding-box regression loss to refine localization optimization and produce more accurate object predictions. Comprehensive experiments show that DWEC-YOLO surpasses several representative lightweight detectors, including YOLOv5n, YOLOv7-Tiny, YOLOv8n, YOLOv10n, and YOLOv12n, in detection effectiveness. Relative to the original YOLO11 architecture, DWEC-YOLO improves precision, recall, and mAP@0.5 by 4.28, 4.46, and 2.65 percentage points, respectively, achieving 96.17%, 95.25%, and 97.57%.

Although numerous ethograms have been developed for lions, the lack of standardization and variability in content hinder comparative research and welfare assessment. This study aimed to develop a comprehensive ethogram for lions, based on a systematic review of published sources (following PRISMA guidelines), critical examination of definitions, and video-based observations of captive individuals. As a result, we propose a new ethogram comprising 83 behavioural patterns grouped into 13 functional categories: affiliative (10), aggressive (2), agonistic (7), environment-directed (9), fear-related (2), feeding (9), locomotor (8), maintenance (5), marking (5), potentially stereotypic (7), reproductive (4), resting (7), and other behaviours (8). This ethogram is designed to be both comprehensive and adaptable, supporting its potential application across diverse research contexts, from behavioural monitoring to welfare evaluations.

Earlier research indicated that a <i>Scutellaria baicalensis</i> extract at 8 mg/mL markedly suppressed the growth, motility, and biofilm-forming capacity of <i>V. alginolyticus</i> ND-01 (OD₆₀₀ = 0.5) following 12 h of treatment, with the resulting stress substantially altering the expression of multiple genes, including <i>gspJ</i>, <i>gspL</i>, and <i>gspM</i>.
