文献和实验Visible Lights Combined with Photosensitizing Compounds Are Effective against Candida albicans Biofilms.
Fungal infections are increasing in prevalence worldwide, especially in immunocompromised individuals. Given the emergence of drug-resistant fungi and the fact that there are only three major classes of antifungal drugs available to treat invasive fungal infections, there is a need to develop alternative therapeutic strategies effective against fungal infections. Candida albicans is a commensal of the human microbiota that is also one of the most common fungal pathogens isolated from clinical settings. C. albicans possesses several virulence traits that contribute to its pathogenicity, including the ability to form drug-resistant biofilms, which can make C. albicans infections particularly challenging to treat. Here, we explored red, green, and blue visible lights alone and in combination with common photosensitizing compounds for their efficacies at inhibiting and disrupting C. albicans biofilms. We found that blue light inhibited biofilm formation and disrupted mature biofilms on its own and that the addition of photosensitizing compounds improved its antibiofilm potential. Red and green lights, however, inhibited biofilm formation only in combination with photosensitizing compounds but had no effects on disrupting mature biofilms. Taken together, these results suggest that photodynamic therapy may be an effective non-drug treatment for fungal biofilm infections that is worthy of further exploration.
实验69 生长延缓剂B 9 对花生茎节生长的影响 原理 B9 (Alar)的化学名称是N,N—二甲基琥珀酰胺酸,其结构式如下: B9 是一种人工合成的植物生长延缓剂,有阻止细胞分裂与细胞伸长的作用。以适宜浓度的B9 溶液喷施花生植株,能使植株变矮,节间变短,抑制茎枝徒长,减少养分消耗。在生产实践上有一定的意义。 仪器药品
