Determination of Pyrrolizidine Alkaloids in Tea and Herbal Infusions by LC-MS/MS

Pyrrolizidine alkaloids (PAs) and N-oxides (PANOs) are food-safety hazards subject to regulatory limits, and their occurrence in teas and herbal infusions (THI) represents a dietary route. This study aimed to develop and validate a liquid chromatography-tandem mass spectrometry (...

Resistant Candida spp. in Healthy Individuals: Mapping a Surveillance Blind Spot

The prevalence and characteristics of resistant, biofilm-forming Candida strains in healthy individuals remain poorly understood. In this work, Candida strains from 23 healthy volunteers and 11 candidiasis patients (n = 34) were isolated and characterized. Biofilm formation capac...

Preclinical Evaluation of Combined Polo-like Kinase 1 Inhibition and Navitoclax in Experimental Models of Lung Cancer

Targeted therapies have substantially advanced cancer treatment; however, therapeutic resistance remains a major challenge, particularly in lung cancer. Polo-like kinase 1 (PLK-1), a key regulator of mitosis, is frequently overexpressed in lung tumors and has emerged as an attrac...
