In this study, Zinc oxide nanoparticles (ZnO NPs) were synthesized using Oxalis stricta leaf extract via an eco-friendly green synthesis approach and evaluated for their anticancer potential against colon cancer. Characterization by UV-VIS spectroscopy, Dynamic Light Scattering, Scanning Electron Microscopy, Fourier-transform Infrared spectroscopy, and X-ray Photoelectron Spectroscopy confirmed the nanoscale size, stability, and surface functionalization of the ZnO NPs. Cytotoxicity evaluation using the MTT assay revealed a dose-dependent anti-proliferative effect on colon cancer cells, with an IC₅₀ value of 30.27 µg/mL. Hemolysis assay indicated good biocompatibility with minimal red blood cell lysis. Apoptosis induction was evidenced by fluorescence staining techniques, including DAPI, AO/EB, DCF-DA, and Rhodamine 123, revealing nuclear condensation, oxidative stress, and mitochondrial membrane disruption. In silico molecular docking demonstrated strong binding interactions between phytoconstituents of Oxalis stricta and cancer-related targets MMP-9, GSK3β, and Bcr-Abl.

This study collected macroinvertebrates from a typical urban river in the Pearl River Delta region during the dry season (December 2021 to January 2022) and the wet season (May to June 2022). Family sensitivity values (FSVs) were revised based on local biotic and abiotic data to adjust the Biological Monitoring Working Party (BMWP) and Average Score per Taxon (ASPT) indices. The relationship between biological indices and the Water Quality Index (WQI) was analyzed, and the differences before and after indices adjustment were compared. The results indicated that the revised FSVs for 24 families showed a decreasing trend, with lower FSVs in the dry season compared to the wet season. This pattern reflects the minimum environmental tolerance threshold for macroinvertebrates. Compared to the original indices, the adjusted ASPT exhibited a stronger linear correlation with the WQI in both seasons, while the adjusted BMWP showed a significant correlation only in the wet season, indicating that the adjusted ASPT is more accurate than the adjusted BMWP in evaluating water quality.

While natural vaginal delivery is the safest, it is not always feasible due to diverse circumstances. In such cases, assisted delivery techniques, such as vacuum-assisted delivery (VAD), may facilitate vaginal birth. However, this technique can be associated with a higher risk of maternal injuries, potentially resulting in long-term conditions such as pelvic organ prolapse or incontinence. This study investigates the biomechanical impact of VAD on maternal tissues, aiming to reduce these risks. A finite element model was developed to simulate VAD, incorporating maternal musculature, a deformable fetal head, and a vacuum cup. Twelve simulations were conducted, varying contraction durations, resting intervals, and the number of pulls required for fetal extraction. Results revealed that prolonged contraction durations, coupled with extended resting intervals, lead to a reduction in pelvic floor stress. Elevated stress levels were observed when fetal extraction involved two pulls, with an 8.43% decrease in maximum stress from two pulls to four. The peak stress recorded was 0.81 MPa during a 60-second contraction, followed by a 60-second rest period. These findings indicate that longer maneuvers may reduce trauma, as extended pulls allow muscles more time to relax and recover during both contraction and rest phases. Furthermore, an increased number of pulls extends the duration of the maneuver, facilitating fetal rotation and improved adjustment to the birth canal. This study offers crucial insights into the biomechanics of childbirth, providing clinicians with valuable information to enhance maternal outcomes and refine assisted delivery techniques.</p>","PeriodicalId":489,"journal":{"name":"Biomechanics and Modeling in Mechanobiology","volume":" ","pages":"1435-1446"},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12245992/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144323998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
