Evidence for occurrence of an organophosphate-resistant type of acetylcholinesterase in strains of sea lice (Lepeophtheirus salmonis Kroyer)

, 2004
Acetylcholinesterase (AChE) is the target of a major pesticide family, the organophosphates, which were extensively used as control agents of sea lice on farmed salmonids in the early 1990s.

Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Inhibition of Muscle-Specific Protein Kinase (MuSK) Releases Organophosphate-Aged Acetylcholinesterase (AChE) from C2C12 Cells

Toxics
Mechanistically, OPs inhibit acetylcholinesterase (AChE), an enzyme that terminates cholinergic transmission, triggering a sustained activation of acetylcholine receptors.

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

Journal of Agrarian Change, EarlyView.
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...

Developing a Bioscavenger Against Organophosphate Nerve Agents

, 2017
Organophosphate poisoning can occur from exposure to agricultural pesticides or chemical weapons. This exposure inhibits acetylcholinesterase resulting in increased acetylcholine levels within the synaptic cleft causing loss of muscle control, seizures ...

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

Journal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...
