Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),
