Occurrence and levels of glyphosate and AMPA in shallow lakes from the Pampean and Patagonian regions of Argentina
(Pergamon-Elsevier Science Ltd, 2018-06)
Glyphosate (N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide used to kill weeds that compete with commercial crops. In Argentina, the use of glyphosate-based herbicides increased dramatically (up to ...
A novel fluorimetric method for glyphosate and AMPA determination with NBD-Cl and MCR-ALS
(Pergamon-Elsevier Science Ltd, 2019-05)
We report the development of a new analytical method for the quantification of N-(phosphonomethyl)glycine (glyphosate) and (aminomethyl)phosphonic acid (AMPA) by combining spectrofluorimetry and multivariate calibration. ...
Central nitric oxide modulates hindquarter vasodilation elicited by AMPA receptor stimulation in the NTS of conscious rats
(Amer Physiological Soc, 2006-05-01)
Microinjection of S-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid ( AMPA) in the nucleus of the solitary tract (NTS) of conscious rats causes hypertension, bradycardia, and vasoconstriction in the renal, mesenteric, ...
Environmental fate of glyphosate and aminomethylphosphonic acid in surface waters and soil of agricultural basins
(Elsevier, 2013-07)
Argentinian agricultural production is fundamentally based on a technological package that combines notill and glyphosate in the cultivation of transgenic crops. Transgenic crops (soybean, maize and cotton)occupy 23 million ...
Sensitivity of AMPA receptor channel to calcium oscillations: A computational study
(2003-06-01)
We used a computational model of biochemical pathways that are involved in the phosphorylation/dephosphorylation of AMPA receptor to study the receptor responses to calcium oscillations. In the model, the biochemical ...

Determinação de glifosato e AMPA nas águas superficiais da Bacia do Paraná 3
(Universidade Estadual Paulista (Unesp), 2018-02-20)
Atualmente, o glifosato é o herbicida de maior uso para o controle de ervas daninhas, sendo muito utilizado em culturas resistentes, como soja e milho. O glifosato é aplicado diretamente sobre a folhagem das plantas, porém ...
Rapid and direct determination of glyphosate and aminomethylphosphonic acid in water using anion-exchange chromatography with coulometric detection
(ELSEVIER SCIENCE BV, 2008)
A simple, rapid, and low-cost coulometric method for direct detection of glyphosate and aminomethylphosphonic acid (AMPA) in water samples using anion-exchange chromatography and coulometric detection with copper electrode ...
Metabolic profiling of glyphosate-resistant sourgrass (Digitaria insularis)
(Cambridge Univ Press, 2020-10-01)
Putative glyphosate-resistant sourgrass was collected to determine its resistance level and to evaluate its metabolic profile after resistance. Although accumulation of shikimic acid is known to occur in glyphosate-susceptible ...
