Association between pancreatic adenocarcinoma risk and concentration of organochlorine pesticides in adipose tissue and urine: A targeted‐screening analysis case‐control study (PESTIPAC)

United European Gastroenterology Journal, Volume 12, Issue 7, Page 951-959, September 2024.
Abstract Background Knowledge about environmental pancreatic adenocarcinoma (PA) risk factors, including pesticide exposure, remains limited. Organochlorine (OC) accumulates in adipose tissue and can help reflect long‐term exposure. Patients and Methods Age and body mass index (BMI) of patients with PA were matched with those undergoing a surgery for a

Rapid Screening of 300 Pesticide Residues in Commercially Available Vegetable‐, Fruit‐, and Cereal‐Based Baby Foods by Using Amino‐Functionalized Multiwalled Carbon Nanotubes with QuEChERS and Gas Chromatography‐Electrostatic Field Orbitrap High‐Resolution Mass Spectrometry

Journal of Food Quality, Volume 2024, Issue 1, 2024.
A new method for screening 300 pesticide residues in fruit‐, vegetable‐, and cereal‐based baby foods by an improved QuEChERS purification method based on amino‐functionalized multiwalled carbon nanotubes (NH2‐MWCNTs) combined with gas chromatography‐electrostatic field orbitrap high‐resolution mass spectrometry (Orbitrap GC‐MS) was developed.

Fipronil induces CYP isoforms in rats

, 2015
The goal of the present study was to evaluate fipronil effects on the activities of drug metabolizing enzymes in rat liver microsomes. Rats were orally treated with fipronil at doses of 1, 5, 10 and 15 mg/kg bw/day for 6 days.

Long-Term Fipronil Treatment Induces Hyperactivity in Female Mice

, 2020
Fipronil is an insecticide widely used for veterinary and agricultural purposes. While its insecticidal properties mostly rely on its high affinity antagonistic activity on insect γ aminobutyric acid (GABA) receptors, fipronil and its main ...

Disposition of fipronil in rats

, 2013
International audienceIn the scientific literature, little attention has been paid to the disposition of fipronil, a phenyl pyrazole insecticide. In this study, the tissue distribution, the metabolic fate, and the elimination of fipronil was investigated

A rodent and tick bait for controlling white-footed mice (Peromyscus leucopus) and blacklegged ticks (Ixodes scapularis), the respective pathogen host and vector of the Lyme disease spirochetes.

Ticks and Tick-Borne Diseases
A promising alternative approach to conventional vector and rodent control practices is the use of a bait containing a rodenticide and acaricide in controlling vectors and pathogen reservoirs concurrently.
