Bacteria prevalent in the hospital environment have developed multi-drug resistance (MDR), such as the carbapenemase-producing Klebsiella pneumoniae (KPC+). Photodynamic therapy (PDT), which uses light-activated photosensitizer compounds (PSs), has emerged as an alternative to antibiotics. Cationic-PSs have a better bactericidal effect...

A simple and rapid dispersive liquid-liquid microextraction method coupled with gas chromatography and mass spectrometry was applied for the determination of glyoxal as quinoxaline, methylglyoxal as 2-methylquinoxaline, and diacetyl as 2,3-dimethylquinoxaline in red ginseng products. The performance of the proposed...
