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.

MULTICOMPONENT DETERMINATION OF ORGANOCHLORINATED COMPOUNDS IN MILK BY GAS CHROMATOGRAPHY WITH ELECTRON-CAPTURE DETECTION AFTER LIQUID-LIQUID EXTRACTION

Agricultura, 2009
This paper reports a multiresidue analytical method based on liquid-liquid extraction and capillary gas chromatography with electron-capture detection (LLE-GC-ECD). The determined analytes belong to two organochlorinated compound classes: polychlorinated

Polychlorinated biphenyls, organochlorine pesticides and neurodevelopment [PDF]

Current Opinion in Pediatrics, 2008
Although environmental levels of polychlorinated biphenyls and certain organochlorine pesticides--hexachlorobenzene, dichlorodiphenyl trichloroethane and its primary metabolite, dichlorodiphenyl dichloroethene--are generally on the decline, early-life exposures to these prevalent contaminants continue.

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).

FXTAS and the Spectrum of FMR1 Premutation‐Associated Phenotypes in Latin America: A Scoping Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Fragile X–associated tremor/ataxia syndrome (FXTAS) is a late‐onset neurodegenerative disorder caused by FMR1 premutation expansions (55–200 CGG repeats). Although well described in populations of predominantly European ancestry, FXTAS remains poorly characterized in Latin America due to limited awareness, restricted access to ...

Pesticide residues in Junca Onion (Allium fistulosum) cultivated in Risaralda, Colombia

Semina: Ciências Agrárias, 2020
By 2050, the world population will reach 9.2 billion, increasing the food demand by twice. Lowering loss due to pests is still challenging, where pesticides play an important role, but its indiscriminate use causes inadequate residual amounts to be ...
