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).

Lack of fitness cost associated to CYP9K1‐mediated insecticide resistance in Anopheles funestus, represents a threat to vector control

Pest Management Science, EarlyView.
The 454A‐CYP9K1‐mediated resistance confers fitness advantages regarding pupation and longevity in Anopheles funestus, resulting to a slow susceptibility reversion. By contrast, the 119F‐GSTe2 resistance allele rapidly declines. Abstract BACKGROUND Resistance management is critical to maintain insecticide effectiveness in malaria control, and ...

Organochlorines, perfluoroalkyl substances, mercury, and egg incubation temperature in an Arctic seabird: Insights from data loggers [PDF]

, 2018
In birds, incubation‐related behaviors and brood patch formation are influenced by hormonal regulation such as prolactin secretion. Brood patch provides efficient heat transfer between the incubating parent and the developing embryo in the egg ...

Isolation of Bacteria from Agricultural Soils and Evaluation of Their Degradative Capacity for Organochlorine and Organophosphorus Pesticides

Agronomy
In this work, OP- and OC-degrading bacteria were isolated from agricultural soil samples taken in the department of Bolivar, Colombia. The objective of this research was to degrade organochlorine and organophosphorus pesticides using bacterial colonies ...

Complex organochlorine pesticide mixtures as determinant factor for breast cancer risk: a population-based case–control study in the Canary Islands (Spain)

Environmental Health, 2012
Background All the relevant risk factors contributing to breast cancer etiology are not fully known. Exposure to organochlorine pesticides has been linked to an increased incidence of the disease, although not all data have been consistent.

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Diflubenzuron Caused Mitochondrial Dysfunction, Ca2+ Homeostasis Disruption, and Intrinsic Apoptosis in Trophoblastic Cells

Environmental Toxicology, EarlyView.
ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+
