This flow passes over a thin moving slender needle including gyrotactic motile microorganisms through a porous medium. The study examines how various physical characteristics, such as Cattaneo-Christov heat and mass flow, and viscous dissipation, affect the system's flow. Our objective is to find the impact of pertinent parameters on velocity, temperature, concentration, and microorganisms. This type of flow problem is important to control the heat and fluid flow phenomena around a needle which are applied to biotechnology (bioreactors, microbial fuel cells), biomedical engineering, microfluidics, and cooling systems. The reason for this investigation combines both scientific curiosity and practical applications. The controlling equations are simplified into nonlinear ordinary differential equations, solved numerically via MATLAB bvp4c tool, and their impact on temperature, velocity, microorganism, and concentration outline is graphically depicted, also, their impact on local microorganism's number, local Sherwood number, frictional drag coefficient, and local Nusselt number, are tabulated. This study's novelty is that it fills the gaps left by Kandasamy et al. [31]. This study demonstrates great agreement with Kandasamy et al. [31]. The study's findings indicate that improvement of thermal and concentration relaxation parameters declines fluid temperature and concentration respectively.

Despite their effectiveness, current cancer treatments frequently have serious side effects, which emphasizes the need for safer and more efficient therapeutic alternatives. Procyanidolic oligomers (PCOs), natural antioxidants derived from grape seeds, have shown promise as anticancer agents, particularly in diseases driven by oxidative stress. Building on this foundation, we hypothesized that nanoformulation of PCOs could enhance their therapeutic potential. In this study, we synthesized a stable nanoformulation of PCOs (termed PCOs–NF) using a modified desolvation method and characterized it through SEM and TEM analyses, revealing a consistent spherical morphology and an average diameter of 156 nm. The anticancer efficacy of PCOs–NF was evaluated against MCF-7 (human breast cancer), L-132 (human lung cancer), and HBL-52 (human brain meningioma) cell lines using the MTT assay. Results demonstrated significant inhibition of cell viability, with values of 36.46 %, 33.97 %, and 36.30 %, respectively, at a concentration of 125 μg/ml—exceeding the performance of conventional anticancer drugs. These findings highlight the potent anticancer activity of PCOs–NF against key cell lines involved in breast cancer metastasis to the lungs and brain. The study underscores the potential of PCOs–NF as a natural, selective, and efficient therapeutic option for metastatic breast cancer therapy. Further research and clinical validation could pave the way for its development as a safer alternative to conventional treatments for metastatic cancers.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"9 ","pages":"Article 100400"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143092225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
