This study explores the use of Photodynamic Therapy (PDT) to prevent fungal cell migration from ETT surfaces to lungs, focusing on the role of curcumin as a photosensitizer. ETTs were coated with varying concentrations of curcumin, and biofilm formation was measured after applying PDT with a 50 J/cm2 irradiation dose. The study found that ETTs functionalized with a one-third concentration of CUR reduced biofilm formation by 1.78 Log, significantly lowering microbial load and potentially decreasing hospital-acquired infections. Confocal fluorescence microscopy confirmed that PDT damaged the biofilm's extracellular matrix and caused detachment of dead fungal cells. Moreover, the fluorescence analysis reveals the photodegradation behavior of the photosensitizer within the tube, providing critical insights into its stability and durability, which are essential for evaluating the long-term applicability of these tubes in clinical settings. These results suggest PDT as a promising strategy to reduce fungal infections in high-risk patients, offering potential for future clinical application in preventing device-associated infections.","PeriodicalId":20133,"journal":{"name":"Photochemistry and Photobiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Porphyrins are the most widely used photosensitizers due to their biocompatible nature. Aggregation-induced emission (AIE) characteristics of photosensitizers are one of the advantageous features that will enhance fluorescence, intersystem crossing, and efficient triplet state generation. Herein, we demonstrate two glycosylated porphyrin photosensitizers, ZnGEPOH (with two ethynyl groups) and ZnGPOH (without two ethynyl groups), which exhibit AIE. Detailed studies revealed that ZnGEPOH exhibited a two-fold increase in singlet oxygen production than ZnGPOH due to AIE. The photo-cytotoxicity of ZnGPOH and ZnGEPOH were evaluated using cancer cell lines A549 and AGS. ZnGEPOH shows superior photo-cytotoxicity with cell viability of 21% and 19% for A549 and AGS, respectively, at 250 μg/mL concentration in 48 h.

This prospective observational study involved a 36-month follow-up of physicians working in an ophthalmic examination room equipped with 222-nm UV-C lamps. Initially, a 12-month observation showed no signs of acute or chronic ocular damage. To further substantiate these findings, the study period was extended to 36 months, during which four participants underwent regular ocular examinations, including assessments of visual acuity, refractive error, and corneal endothelial cell density. The irradiation dose was meticulously controlled to remain within the previous threshold limit of 22 mJ/cm2 over an 8-h period, as advised by the ACGIH prior to 2022. Results indicated no significant changes in these parameters, suggesting no clinically significant ocular hazards associated with prolonged exposure to 222-nm UV-C irradiation under real-world conditions. Additionally, no delayed side effects, such as pterygium, keratopathies, or cataracts, were observed. Our study supports the safe use of 222-nm UV-C for microbial disinfection in occupied environments and provides a robust foundation for updated safety guidelines.","PeriodicalId":20133,"journal":{"name":"Photochemistry and Photobiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For antioxidant properties, the EC50 values of DPPH and ABTS radical scavenging activity for CE were 1.27 and 5.20 mg/mL, respectively. It significantly reduced NF-κB, MMP-3 and MMP-9 protein expression levels, and increased IκB and TIMP-1 expression level in UVA-irradiated HaCaT cells. In the skin aging mice model, CE reduced the degree of UV-induced skin photoaging. Histological study confirmed that CE can ameliorate the adverse effects of UV exposure on the skin. Moreover, we found that CE could enhance the activities of Superoxide dismutase (SOD), and increased the contents of hydroxyproline (HYP) in photoaged mice skin.

Short white light pulses induce rapid and large seismonastic-like movements (denoted \"photostimulation\") of the primary pulvini in various leaves within 120 s after the onset of light. An early event recorded is a wavelength-related modification of the plasma membrane difference: potential depolarization under white, blue, green, and red wavelengths, and hyperpolarization under far red wavelengths (and also in darkness). The photoreactivity of the pulvini is controlled by a circadian rhythm and modulated by the applied diurnal photoperiod cycle (photophase ranging from 6 to 18 h). The reactivity varied among plants and even between leaves on the same plant. The level of reactivity is related to the photon fluence rate in the range from 10 to 140 μmol m-2 s-1 under white light and to the experimental temperature in the range 15°C-35°C. An \"accommodation\" to light supply is evidenced by a modulation of the reactivity in relation to the schedule of light application under low fluence rates and the introduction of short darkness intervals during the first 30-s light pulse.

The evolution of the photocatalytic reaction was chemometrically analyzed using Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) of the spectroscopic data to obtain the kinetic and spectral decomposition of the RhB derivatives involved in the reaction. This was then compared with the results obtained by standard HPLC analysis. The MCR-ALS analysis yielded satisfactory spectral and kinetic profiles for RhB and the fully deethylated product, Rhodamine 110. However, the spectral profiles for the N-triethyl (3EtRh) and the mixture of the two isomeric N-diethyl (2EtRh) derivatives exhibited some spectral distortions due to significant spectral overlap between these compounds. In contrast to the HPLC analysis, the MCR-ALS could not resolve the N-ethylrhodamine (EtRh) derivative. The deethylation reactions occurred via independent zero-order steps at the surface of TiO2, indicating that the RhB degradation reaction is governed by the adsorption-desorption equilibrium of the dye and derivatives on the photocatalyst surface, thereby enhancing the diffusion of compounds on the surface.","PeriodicalId":20133,"journal":{"name":"Photochemistry and Photobiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142688633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chatbots were moderately effective in answering queries concerning fundamental concepts in photochemistry but were glaringly deficient in specialized queries for dyes and fluorophores.
