The purpose of this study was to carry out pharmacognostic identification and quality evaluation of FFK for the establishment of quality control standards. The methods included organoleptic evaluation, microscopic observation, proximate analyses, qualitative chemical analysis, thin-layer chromatography (TLC) fingerprinting, and high-performance liquid chromatography (HPLC). The leaves of FFK were light green, and the roots were fusiform and thick. The resin was milky white in its fresh state, and it became a yellowish-brown irregular mass after air drying. Under the microscope, the secondary structure of the root was developed, and the resin ducts were mainly distributed in the cortex. The powder contained vessels, oil cells, fibers, starch granules, parenchyma cells, resin ducts, and stone cells, but the resin powder contained only resin mass. The ash, moisture, extract, and heavy metal contents in FFK complied with general standards of similar medicinal materials in the Chinese Pharmacopeia (ChP). Qualitative chemical analysis showed that FFK contained terpenoids, flavonoids, coumarins, and volatile oils. A TLC fingerprint was established for FFK. HPLC showed that the ferulic acid content in FFK was 0.5518 mg g<sup>−1</sup>. This study preliminarily established the pharmacognostic identification standard for FFK and, combined with quality evaluation, could lay a foundation for its comprehensive development and utilization.</p>\u0000 </div>","PeriodicalId":18684,"journal":{"name":"Microscopy Research and Technique","volume":"88 10","pages":"2721-2732"},"PeriodicalIF":2.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144326271","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}

By integrating light and electron microscopy, this method provides a comprehensive, time-resolved analysis of nanoparticles accumulation within plant roots and their biosorption within a dynamically formed biofilm surrounding the root surface. Red radish sprouts were selected as an ideal model due to their rapid germination, well-developed fibrous root system, and high sensitivity to environmental changes, making them suitable for studying nanoparticle-plant interactions. To assess the role of microbial activity in nanoparticle transformation and bioavailability, a carbon nanodot fluorescence quenching technique was employed as a sensitive sensor-based approach to detect and monitor dissolved iron ions in colloidal suspensions. Results confirmed that no free iron ions were released into the effluent, indicating that uptake occurred exclusively in nanoparticulate form. The light microscopic images demonstrated that the biofilm matrix around the roots acted as a retention and filtration system, selectively adsorbing and concentrating colloidal particles near the root surface. Additionally, cross-sectional root tissue analysis using scanning electron microscopy (SEM) revealed that the smallest nanoparticles were able to penetrate plant tissues and undergo intracellular phytoaccumulation. Further energy-dispersive X-ray spectroscopy (EDS) mapping showed an exponential-like time-dependent increase in iron accumulation within root tissues, suggesting a pattern primarily driven by passive diffusion along concentration gradients. These findings provide novel insights into the mechanisms governing nanoparticle uptake in plants, emphasizing the role of plant-microbe interactions in modulating colloidal bioavailability. By elucidating the dynamics of nanoparticle accumulation and retention in plant-microbe systems, this study advances our understanding of phytoremediation processes and offers valuable implications for sustainable environmental remediation and precision agriculture applications.</p>\u0000 </div>","PeriodicalId":18684,"journal":{"name":"Microscopy Research and Technique","volume":"88 10","pages":"2690-2703"},"PeriodicalIF":2.1,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144225917","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}

Particularly, sericin-conjugated NPs induced more prominent effects in the animal model. The histopathological analysis of the spleen and mammary tissues showed cytotoxic effects in the DMBA group, and sericin-conjugated NPs were highly effective and minimized the cytotoxic effects of DMBA.

The physical damage to these whorls can alter the characteristics of the flowers, compromise their functions, and consequently impact fertility and reduce the reproductive success of the species. We provide the floral anatomical description of <i>Senna aversiflor</i>a (Herb.) H.S. Irwin and Barneby. We measured various anatomical traits of petals and quantified the levels of chemical compounds and the pollen produced by intact and damaged flowers in order to identify characters associated with the plant-florivore interaction. We found that the epidermis (adaxial and abaxial surfaces) and mesophyll of the petals of healthy flowers were thicker when compared to damaged flowers. We infer that the smaller thickness of traits associated with the absence of characters with deterrent effect on herbivores and greater production of attractive/nutritive chemical compounds in relation to defense compounds contribute to making the species highly susceptible to florivory. Pollen production in damaged flowers did not differ between the different stages of floral development. However, florivory has a negative effect on the amount of pollen produced. Damaged flowers had less pollen than healthy flowers.
