This provides a promising approach for accurate cancer staging and identifying spectral differences between cancerous and healthy tissues. In this study, NIR data from esophageal lesions excised via endoscopic submucosal dissection were analyzed using partial least squares discriminant analysis (PLS-DA) to classify normal tissues, low-grade, and high-grade intraepithelial neoplasia, confirming its feasibility for staging diagnosis. To enhance wavelength selection, the FOX algorithm, a swarm intelligence optimization method, is improved with two modifications: a nonlinear time-varying sigmoid transfer function and mirror selection. These enhancements are combined to form an improved FOX algorithm (iFOX) for wavelength selection. iFOX effectively enhances the algorithm's stability while enhancing classification performance.</p>\u0000 </div>","PeriodicalId":184,"journal":{"name":"Journal of Biophotonics","volume":"18 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four hours post-infection, the B16F10 cells underwent phototherapy, and a range of cellular parameters were assessed, including cell viability, melanin content, cell cycle progression, reactive oxygen species (ROS) production, mitochondrial membrane potential (MMP), apoptosis, necrosis, lactate dehydrogenase (LDH) release, and autophagy. The findings indicated that Adv infection elevated melanin content and autophagy, resulting in G1 phase cell cycle arrest. In comparison to the control group, light-treated, Adv-infected cells exhibited reduced inhibition rates, LDH release, apoptosis, and necrosis, while MMP and ROS levels were elevated. The study concluded that although Adv, as a gene delivery vector in conjunction with light therapy, significantly modulated melanin content and autophagy.

In vivo experiments on Ehrlich carcinoma-bearing female Swiss albino mice demonstrated that PPy@Au NCs selectively accumulated in tumor tissue and, when activated by PPLEL, generated sufficient heat for effective tumor ablation. This approach enhanced treatment efficacy and presented a cost-effective solution due to the affordability of both the nanocomposite and light source.
