Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

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

Medicinal Research Reviews, EarlyView.
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),

Enhancing Selective Brain Cancer Therapy: Integrating Nanomedicine and Molecular Dynamics to Target the Cancerous Lipid Composition

Nano Select, EarlyView.
Improving selectivity within therapeutic design is critical to ensure targeted delivery to brain tumors. Targeting the cellular membrane composition distinctive of the blood–brain barrier and brain cancer cells is explored in this review. Nanomedicine can be utilized for precise tumor recognition, and detailed mechanistic interactions of therapeutics ...
