Photodynamic inactivation of bacteriophage T4 particles, mediated by either angelicin or thiopyronin, is enhanced by defects in the T4 uvsW-uvsX-uvsY postreplication repair system but not by a defect in the denV pyrimidine-dimer-excision system. There was no evidence for functional interactions between the two repair systems. As observed previously with 8-methoxypsoralen, photodynamic mutagenes...
1. Photodynamic therapy could be an alternative treatment for highly prevalent local antibiotic-resistant pathogens. 2. Photodynamic inactivation using toluidine blue O was observed on both reference strains and clinical samples, including methicillin-resistant Staphylococcus aureus, e x t e n d e d s p e c t r u m β l a c t a m a s e – p r o d u c i n g Escherichia coli and Klebsiella pneumoni...
Hydrogels are materials consisting of a network hydrophilic polymers. Due to their good biocompatibility and hydrophilicity, they widely used in biomedicine, food safety, environmental protection, agriculture, other fields. This paper summarizes the typical complex photocatalysts, photosensitizers, hydrogels, as week antibacterial activities basic mechanisms photothermal photodynamic effects. I...
Photodynamic action/Acridine orange/tRNA/Guanine/Singlet oxygen The photodynamic inactivation of acridine orange (AO)-sensitized tRNA was investigated with respect to the type of photochemical pathways and the base damage leading to the inactivation. The diagnostic tests for singlet oxygen (1O2), namely the enhancement effect of deuterium oxide (D2O) and the inhibition effect by sodium azide, i...
Opportunistic fungal pathogens may cause superficial or serious invasive infections, especially in immunocompromised and debilitated patients. Invasive mycoses represent an exponentially growing threat for human health due to a combination of slow diagnosis and the existence of relatively few classes of available and effective antifungal drugs. Therefore systemic fungal infections result in hig...
