The taxonomy of the Cardueae is complicated and unresolved, as it contains the largest and most diverse genera. The main distribution centers of the Cardueae are in the eastern and western Mediterranean, the western Irano-Turanian region, central Asia, and North Africa. Using pollen morphology can be a useful tool for the identification and delimitation of Cardueae taxa. Therefore, the current study aims to describe the pollen types of tribe Cardueae based on pollen features. Furthermore, the study addresses the relationships among the genera and species based on palynological features as well as species delimitation based on pollen morphology. Pollen morphology of 39 species of Cardueae distributed in 28 genera was examined by scanning electron microscopy. In the present study, statistical analyses and various clustering and ordination methods were provided for palynological data. Based on these results, the members of nine subtribes of Cardueae showed overlap in palynological data. This extreme heterogeneity of relationships among the taxa of tribe Cardueae could be attributed to the large number of taxa and their high morphological diversity. However, suitable palynological features were distinguished for taxonomic differentiation among the species of Cardueae, including pollen shape, size, polar axis to equatorial diameter ratio [P/E], exine sculpture, and spine size. Consequently, six pollen types were identified in the studied taxa of Cardueae.</p>\u0000 </div>","PeriodicalId":18684,"journal":{"name":"Microscopy Research and Technique","volume":"88 5","pages":"1422-1450"},"PeriodicalIF":2.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142951770","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}

Cold crushing and takilon injection into the renal arteries were performed for scanning electron microscopic examinations. The course and branching of intrarenal capillaries and morphologic features from glomeruli to foramina papillaria were demonstrated. The location, position, shape, weight, and size of the kidneys of the three species studied were determined. Relative medullary thickness (RMT) and kidney index (Ki) values were calculated from the measurements. Based on the RMT values of the three species, it was concluded that they are mammals belonging to the semiarid and humid habitat category. The number of nephrons with long segments was high in the kidneys of all three species. Structural findings suggested that the rat may produce more concentrated urine than the ground squirrel, and the ground squirrel may produce more concentrated urine than the rabbit. The mean diameter of the renal corpuscles was 112.5 μm in the hibernated ground squirrel, 137.6 μm in the nonhibernated ground squirrel, 138.1 μm in the rabbit, and 137.8 μm in the rat. In hibernated ground squirrels, a narrowing of the cavum glomeruli and a decrease in renal corpuscle diameters were found. In contrast to ground squirrel and rat kidneys, rabbit kidneys showed the presence of species-specific subcapsular glomeruli. Immunohistochemistry (antinestin antibody) staining and scanning electron microscope (SEM) images revealed the structure of podocytes in detail.

In view of the limitations of existing methods and the diversity of AFM images, an AFM image level distortion correction method based on automatic feature marking is proposed. The Canny edge detection algorithm with adaptive threshold is used to automatically detect and recognize the feature graphics, and the feature graphics are zeroed by the hole filling algorithm to automatically remove the feature graphics data from the line fitting data. After completing the least squares fitting correction of all the rows of data, the full AFM image data with eliminating horizontal distortion can be obtained.

The increase in these cells is usually a sign of certain virus infections, so their detection plays an important role in the fight against diseases. Manual detection of reactive lymphocytes is undoubtedly time-consuming and labor-intensive, requiring a high level of professional knowledge. Therefore, it is highly necessary to conduct research into computer-assisted diagnosis. With the development of deep learning technology in the field of computer vision, more and more models are being applied in the field of medical imaging. We aim to propose an advanced multi-object detection network and apply it to practical medical scenarios of reactive lymphocyte detection and other leukocyte detection. First, we introduce a space-to-depth convolution (SPD-Conv), which enhances the model's ability to detect dense small objects. Next, we design a dynamic large kernel attention (DLKA) mechanism, enabling the model to better model the context of various cells in clinical scenarios. Lastly, we introduce a brand-new feature fusion network, the asymptotic feature pyramid network (AFPN), which strengthens the model's ability to fuse multi-scale features. Our model ultimately achieves mAP50 of 0.918 for reactive lymphocyte detection and 0.907 for all leukocytes, while also demonstrating good interpretability.

This study explored the synthesis and characterization of silver NPs (AgNPs) and examined their impact on the growth of <i>Zea mays</i>, both alone and in combination with nickel chloride (NiCl₂). A methanolic leaf extract was combined with silver nitrate to synthesize AgNPs. Characterization of NPs was carried out through UV–vis spectroscopy, FT-IR, x-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), and scanning electron microscopy (SEM). Eleven treatments (T1–T11) were made, and <i>Z. mays</i> seeds were subjected to NiCl₂ in pots after being soaked in AgNPs solution. Treatments were arranged to evaluate the effects of NiCl₂ (T1–T3), AgNPs (T4 and T5), and the interactive effects of AgNPs and NiCl₂ (T6–T11) on the planted seeds. UV–vis peaks at 410 nm confirmed the presence of AgNPs. The crystalline nature of AgNPs was confirmed through XRD analysis, and the presence of functional groups from biomolecules and capping agents was shown in FT-IR. The morphology of the NPs and elemental analysis were conducted using SEM and EDS, respectively. The size of the NPs was found 25–50 nm using Nano Measurer software. Growth inhibition was noticed in NiCl₂-treatments T1–T3. Maximum growth and 100% seed germination were observed in NP-treated seeds (T4 and T5). These two treatments also showed the highest germination index, root/shoot growth, and fresh/dry weights. In treatments T6–T11, the interaction between NiCl₂ and AgNP-soaked seeds showed that while AgNP concentrations alone promoted growth, this enhancement was suppressed by the presence of NiCl₂ in the soil. The inhibited values of T6–T11 were still greater than the control, indicating that soaking <i>Z. mays</i> seeds in AgNPs enhanced growth and mitigated nickel stress in the soil. Pigments, carbohydrates, and protein contents were highest in T4 and T5, whereas NiCl₂ reduced these values. Synthesized AgNPs could enhance <i>Z. mays</i> growth and reduce nickel stress at the applied amounts.

However, the high spatial resolution of these images poses significant challenges for manual quantitative evaluation. This project proposes using computer-aided analysis methods to address these challenges, enabling rapid and precise clinical diagnosis, course analysis, and prognostic prediction. This research introduces advanced deep learning frameworks such as squeeze-and-excitation and dilated dense convolution blocks to tackle the complexities of quantifying small and intricate breast cancer tissues and meeting the real-time requirements of pathological image analysis. Our proposed framework integrates a dense convolutional network (DenseNet) with an attention mechanism, enhancing the capability for rapid and accurate clinical assessments. These multi-classification models facilitate the precise prediction and segmentation of breast lesions in microscopic images by leveraging lightweight multi-scale feature extraction, dynamic region attention, sub-region classification, and regional regularization loss functions. This research will employ transfer learning paradigms and data enhancement methods to enhance the models' learning further and prevent overfitting. We propose the fine-tuning employing pre-trained architectures such as VGGNet-19, ResNet152V2, EfficientNetV2-B1, and DenseNet-121, modifying the final pooling layer in each model's last block with an SPP layer and associated BN layer. The study uses labeled and unlabeled data for tissue microscopic image analysis, enhancing models' robust features and classification abilities. This method reduces the costs and time associated with traditional methods, alleviating the burden of data labeling in computational pathology. The goal is to provide a sophisticated, efficient quantitative pathological image analysis solution, improving clinical outcomes and advancing the computational field. The model, trained, validated, and tested on a microscope breast image dataset, achieved recognition accuracy of 99.6% for benign and malignant secondary classification and 99.4% for eight breast subtypes classification. Our proposed approach demonstrates substantial improvement compared to existing methods, which generally report lower accuracies for breast subtype classification ranging between 85% and 94%.
