For hematological disorder detection, existing techniques face various limitations, including noise, weak edges, and intensity inhomogeneity. To rectify these problems, a novel Residual-Shuffle2DConv-Squeeze Network approach is proposed in this research to enhance the blood cell segmentation for hematological disorder diagnosis. Distinguishing blood cells, overlapped cells segmentation, edge detection, and morphological operations are the different stages of this approach for performing blood cell segmentation. The Residual-Shuffle Global Attention Network is used for morphological feature extraction, and this network integrates the Residual Network and Shuffle Global Attention Network. To retain fine-grained morphological features and capture variations of blood cell structure, the Residual-Shuffle Global Attention Network model is applied. The Shuffle Global Attention Network module has ShuffleNet and the Global Attention Mechanism. The ShuffleNet reduces the computational cost, and the Global Attention Mechanism helps to preserve crucial features through various layers. Finally, the 2DConv-SNN is applied to detect and classify hematological disorders. The comprehensive experiments are conducted on different datasets, including the Sickle Cell Disease Dataset and the Acute Lymphoblastic Leukemia dataset.

Critical spatial relationships—such as tumor boundaries, stromal organization, and vascular networks—remain obscured, restricting diagnostic accuracy and biological interpretation. HistoNeRF addresses these limitations by adapting Neural Radiance Fields (NeRF) to reconstruct three-dimensional (3D) tissue volumes from routine histological sections. In this study, 84 toluidine blue (TB)–stained murine ovarian sections were digitized, alignment-corrected, and integrated into volumetric models. Tissue segmentation was performed using a convolutional neural network, while visualization was achieved through an interactive, GPU-accelerated interface. To ensure accessibility and reproducibility, a Python-based graphical application (HistoNeRF GUI) was developed following Human–Computer Interaction (HCI) principles and containerized with Docker, allowing installation-free deployment via Docker Hub. HistoNeRF produced high-fidelity 3D reconstructions (SSIM = 0.92; Dice similarity coefficient = 0.88), enabling expert histologists to better visualize follicular structures, stromal compartments, and vascular elements. The containerized GUI was deployed successfully from Docker Hub, providing immediate access to 3D reconstruction without a complex local setup. By overcoming the inherent constraints of 2D microscopy, HistoNeRF enhances the visualization, interpretability, and reproducibility of histological architecture. The HCI-guided, cross-platform interface supports scalability and rapid adoption in digital pathology workflows. Although validation was limited to murine ovarian tissue and one staining protocol, this framework can be extended across tissue types and clinical datasets. HistoNeRF bridges routine histology and 3D volumetric analysis through accurate, interactive reconstructions that advance diagnostic precision and biomedical research. While demonstrated on 84 serial TB-stained ovarian sections, broader validation across tissues, stains, and pathological conditions remains future work; to support this, we provide a Dockerized, modular pipeline for straightforward extension.</p>\u0000 </div>","PeriodicalId":18684,"journal":{"name":"Microscopy Research and Technique","volume":"89 6","pages":"921-931"},"PeriodicalIF":2.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146030275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scanning electron microscopy (SEM) provides high-resolution imaging at these scales. However, the commonly used dehydration-based sample preparation method induces morphological distortions, while environmental SEM requires specialized equipment that is costly and difficult to operate. The NanoSuit method has recently emerged as a promising alternative, enabling SEM observations under high-vacuum conditions without standard (dehydration-based) pretreatment.

We demonstrate that traditional methods frequently cause neuronal transection and loss of fine dendritic processes, particularly during early development of neurons. However, the modified NanoSuit approach preserves neuronal morphology, enabling clear visualization of thin neurites and their interactions. Further, we successfully implemented correlative light and electron microscopy (CLEM) using this method, enabling the colocalization of cytoskeletal proteins such as actin and tubulin with the surface features observed by SEM.

We applied both platforms to sagittal formalin-fixed, paraffin-embedded (FFPE) sections from an orthotopic xenograft mouse model of human medulloblastoma (MB), featuring leptomeningeal seeding (LMS). These longitudinal sections spanning brain and spinal cord allowed simultaneous assessment of areas with distinct cellular architecture. Fifteen-marker mIF was performed.

While macrophages typically serve as key phagocytic cells for clearing lipid debris, exposure to 7KCh disrupts this homeostatic role, contributing instead to dysfunctional foam cell formation. Despite its clinical relevance, the precise morphological and mechanistic effects of 7KCh on macrophages remain insufficiently characterized.

Exposure to increasing concentrations (2–10 μg/ml) of 7KCh for 24 h revealed distinct morphological alterations, including cytoplasmic vacuolization, disrupted cellular architecture and pronounced lipid accumulation. Oil red O staining confirmed the accumulation of neutral lipids, while functional assays demonstrated impaired pinocytosis and phagocytosis, hallmark features of foam cell transformation.
