Different pressures and locations may elicit varying physiological responses. This study investigates whether local and systemic reactions vary with pressure and cuff location.Methods: Healthy volunteers underwent arterial occlusion at the wrist or upper arm using a cuff inflated to 150 or 200 mmHg. Remote photoplethysmography (rPPG) was used to monitor the occluded and control hands. We analyzed AC components (heart rate, respiratory rate, low-frequency activity) and signal amplitude changes in red and green channels during occlusion and reperfusion.Results: No significant differences were observed in local responses between 150 and 200 mmHg occlusions or between cuff positions.Conclusions: These findings establish 150 mmHg cuff pressure on the lower arm as a suitable arterial occlusion protocol and support rPPG for detecting perfusion changes. Minor systemic differences were noted compared to the control hand.","PeriodicalId":94068,"journal":{"name":"Journal of biophotonics","volume":"19 3","pages":"e70247"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13022742/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147523288","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}

To improve surgical precision, we employed multiphoton microscopy (MPM) to characterize the microstructural and spectral features of both normal tissue and tumor boundary. The spectral differences between normal choroid and tumor boundary were systematically analyzed using lambda mode MPM. Collagen parameters were quantified by combining with image processing techniques to elucidate the structural alterations of normal tissues and choroidal melanomas. The results of the study demonstrated that the MPM enables label-free identification of tumor boundary, with NADH molecular changes serving as a critical basis for qualitative differentiation. Furthermore, utilizing self-developed image processing algorithms, the alteration of collagen fiber provides a potential quantitative index for identifying the tumor boundary. This study confirms the capability of MPM in identifying tumor boundary. With the advancement of multiphoton endoscopes, it holds promise for providing precise intraoperative guidance during choroidal melanoma resection.","PeriodicalId":94068,"journal":{"name":"Journal of biophotonics","volume":"19 3","pages":"e70241"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147438804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced optical imaging techniques may allow for better localization of dysplasia in BE. Here, we have assessed the potential clinical utility of a previously described multimodal imaging probe combining optical coherence tomography (OCT) with angle-resolved low coherence interferometry (a/LCI) to prospectively identify dysplasia in BE. Imaging was conducted on 37 patients undergoing endoscopic surveillance of BE, yielding co-registered biopsies of 50 esophageal sites. The a/LCI nuclear morphology data were compared to a previous decision line to prospectively predict dysplasia, demonstrating 100% sensitivity, 93% specificity, and 94% overall accuracy. The NPV was 100%, comparable to previous a/LCI studies. The addition of OCT imaging markedly improved PPV and specificity, compared to previous studies with a/LCI alone, illustrating the clinical utility of the combined platform. These findings suggest that combining OCT and a/LCI enables better detection of dysplasia by providing better guidance.","PeriodicalId":94068,"journal":{"name":"Journal of biophotonics","volume":" ","pages":"e202500380"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12880523/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145759092","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}
