Impact of organic pollutants on phenotype and gene expression in human breast cancer cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Human exposure to industrial chemical compounds is widespread and, although often beneficial, prolonged contact may contribute to disease development, including cancer. While many studies have shown organic pollutants (OP) are cytotoxic, few have explored how long‐term exposure alters cell phenotype.

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

Journal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

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).
