The type of oral tumour dictates severity of the disease, treatment options and prognoses. The current tissue-based Raman Spectroscopy (RS) study explores stratification of canine cancers. Raman spectra of histopathologically confirmed normal and oral tumour types namely Epulis, Spindle cell sarcoma (SCS), and Squamous cell carcinoma (SCC) were acquired using a Raman confocal microscope with 532 nm laser, pre-processed and multivariate analyses performed.

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.

LARR employs a self-supervised training scheme to computationally restore the sparsely sampled TPF images to resolution isotropic images by 4-fold axial and 16-fold lateral resolution enhancement. The simulation studies and experimental results demonstrate the excellent performance of LARR to preserve fine structural features with improved signal-to-noise ratio and structure similarity index. Moreover, the TPF imaging system with the LARR is able to achieve 60-fold improved imaging speed and comparable resolution as compared with the conventional TPF system. The outstanding performance makes LARR a potential tool for fast TPF imaging with high resolution.</p>\u0000 </div>","PeriodicalId":184,"journal":{"name":"Journal of Biophotonics","volume":"18 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257661","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}

To validate its efficacy, we conducted scattering experiments in synthetic and human serum samples, exploiting functionalized AuNPs to recognize bacterial lipopolysaccharides as biomarkers for sepsis disease.
