Focusing on two contrasting cell lines, MDA-MB-231 (triple-negative) and MCF-7 (Luminal-A), we utilized advanced microscopy and fluorescence techniques to detect and characterize ecDNA. Our findings reveal a stark difference: MDA-MB-231 cells, known for their high metastatic potential, exhibit a striking abundance of ecDNA, manifested as double minutes and single form with intense fluorescence signals. In contrast, the less aggressive MCF-7 cells harbor significantly fewer ecDNA. This disparity highlights the potential of ecDNA as a key player in cancer progression and a promising target for novel therapies. This research sheds light on the unseen genetic forces driving breast cancer and opens the door to new strategies in cancer treatment. Further research is necessary to understand the mechanisms of ecDNA formation and its role in different breast cancer subtypes.</p>","PeriodicalId":18684,"journal":{"name":"Microscopy Research and Technique","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142903397","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}

The upper, lower, and third eyelids display varying morphological differences that seem to be closely linked to the birds' way of life, indicating adjustments to their environment and eating behaviors. The black-winged kite has large, forward-facing eyes positioned under a bony shelf (lacrimal process) that shades them. Both eyelids have thick, pigmented edges and bear two rows of long, finely modified filoplume feathers, which increase at the anterior canthus. Melanocytes appear in the stratum basale of upper and lower eyelids, and Langerhans cells were observed. Aggregations of lymphatic cells were present under the conjunctival epithelium within the stroma of the lower eyelid (in the orbital zone near the tarsal plate), while they were absent in the upper eyelid and nictitating membrane. The density of goblet cells on the conjunctival surface of the upper eyelid and the nictitating membrane is higher than that of the lower eyelid. The structure of the skin and conjunctiva in both the upper and lower eyelids contains numerous defensive immune cells that maintain ocular safety and hydration.

Kuntze [=Tylophora capparidifolia (Wight & Arn.) Kuntze], belonging to the family Apocynaceae, is a medicinal plant species endemic to the southern Western Ghats, Tamil Nadu, India. The current study sought to investigate the macroscopic, organoleptic, microscopic, physicochemical, and proximate compositional aspects of the fresh and powdered leaf and stem portions of V. capparidifolium. The anatomical peculiarities of the leaf parts reveal a hypostomatic nature with paracytic stomata, the epidermis being made up of thin-walled cells covered with a thick cuticle (5.9 μm), and the hypodermis comprising angular collenchyma cells. The petiole is oval/rounded-ellipse with abundant nonglandular multicellular trichomes ascending from the epidermis. The hypodermis is composed of collenchymatous cells containing many calcium oxalate crystals and silica bodies. Bicollateral vascular bundles with internal and external phloem characterize the leaf, stem, and petiole parts. The stem is covered by a thin cuticle, chlorenchymatous hypodermis, and large gelatinous fiber bundles (124.29 × 81.71 μm). Secondary growth in the stem is characterized by the development of periderm and lignified vascular tissues. Bicollateral vascular bundles are overlaid by irregular sclerenchyma patches (7.07 × 5.36 μm), a parenchymatous cortex, and pith composed of thin-walled parenchyma cells.

It impacts millions, causing significant morbidity through starvation, stunted growth in children, and a variety of gastrointestinal issues. The taxonomy of the Ascaris genus, notably the distinction between A. lumbricoides and Ascaris suum, has led to ongoing debate among parasitologists. Consequently, the current study intends to provide morphological characterization of A. lumbricoides from Pakistan, using scanning electron microscopy to uncover precise anatomical traits that may aid in resolving the taxonomic controversy surrounding the Ascaris genus. A cross-sectional survey of 1641 individuals was undertaken. Participants filled out structured questionnaires and provided informed consent. After anthelmintic treatment, expelled worms were collected in sterile jars, washed, and preserved in a glycerin-alcohol solution for morphometric examination. Histological examination of transverse section of female worm reproductive system was performed. Scanning electron microscopy was used to investigate the head, cuticle, and caudal regions of the worms. Statistical analyses were performed using t-tests and ANOVA, with significance determined as p ≤ 0.05. When the worms were collected, they ranged in hue from light to pale pink to reddish, then grayish-white to creamy white. Female were distinguished on their large size, straight posterior end with no copulatory bursa and vulvar waist, while male worms were dorsally curved at posterior end. Of the 90 worms measured, 33 were males and 57 were females. The adult female Ascaris worms were significantly (p ≤ 0.0001) larger in body length and width as compared to adult male worms. Furthermore, adult females from different districts had significant differences in body length (p = 0.003) and width (p = 0.00004), although male body length did not differ substantially among districts (p = 0.243). Scanning electron microscopy of A. lumbricoides revealed a head with two subventral lips and a dorsal lip, as well as dentigerous ridges and a triradiate mouth. The cuticle had thick, transversely striated patterns, with clear contrasts between the ventral and dorsal surfaces. The male's caudal area contained mammiliform precloacal papillae and a rectangular anal orifice, but the female had a knob-like structure with uneven striation pattern. The transverse section of female reproductive system consists of two large uteri containing developing eggs, coiled ovaries, and oviducts.

Mature male crabs (> 90 mm carapace width, CW) were used to identify the location of the YOs while male juveniles (50-65 mm CW) at three molt stages (intermoult, premoult, postmoult) were dissected for the characterization of 20-Hydroxyecdysone (20E) levels. The yellowish-white, compact, and oval-shaped YOs are located in pairs at the anterior cephalothorax region, beneath the mandibular external adductor muscle, anterior to the branchial chamber space, and around the end of the nerve tract. The YOs index and YO's cell diameter increased from postmoult to premoult; YO's diameter increased only during premoult stage. Under electron microscopy, the YO's surface morphology is rough, bumpy, network-like, and porous, with several lacunar system tubules. High concentrations of haemolymph 20E during premoult correlated with the changes in the characteristics of YOs at this stage. The presence of ecdysteroid in YOs was confirmed by high performance liquid chromatography (HPLC). The characteristics of the YOs of S. olivacea are similar to the YO descriptions of other brachyurans.

The challenges of dataset quality, interpretability, ethical integration, population variety, and picture standardization must be addressed using deep learning for the functional magnetic resonance imaging (MRI) classification of AD in order to guarantee a trustworthy and practical therapeutic application. In this manuscript Classifying AD using a finite basis physics neural network (CAD-FBPINN) is proposed. Initially, images are collected from AD Neuroimaging Initiative (ADNI) dataset. The images are fed to Pre-processing segment. During the preprocessing phase the reverse lognormal Kalman filter (RLKF) is used to enhance the input images. Then the preprocessed images are given to the feature extraction process. Feature extraction is done by Newton-time-extracting wavelet transform (NTEWT), which is used to extract the statistical features such as the mean, kurtosis, and skewness. Finally the features extracted are given to FBPINNs for Classifying AD such as early mild cognitive impairment (EMCI), AD, mild cognitive impairment (MCI), late mild cognitive impairment (LMCI), normal control (NC), and subjective memory complaints (SMCs). In General, FBPINN does not express adapting optimization strategies to determine optimal factors to ensure correct AD classification. Hence, sea-horse optimization algorithm (SHOA) to optimize FBPINN, which accurately classifies AD.
