Glyphosate and Aminomethylphosphonic Acid (AMPA) Modulate Glutathione S-Transferase in Non-Tumorigenic Prostate Cells. [PDF]

Int J Mol Sci, 2023
Glyphosate (GLY) was developed in the early 1970s and has become the most used broad-spectrum herbicide in the world so far. Its main metabolite is aminomethylphosphonic acid (AMPA), and the accumulation of GLY and its derivative compounds raises some ...

Antioxidant Enzyme and Cytochrome P450 Activities Are Involved in Horseweed (Conyza Sumatrensis) Resistance to Glyphosate

Stresses, 2022
The intensive global use of glyphosate has led to the evolution of glyphosate resistant (GR) weed species, including the economically damaging horseweed (Conyza sumatrensis). We evaluated the glyphosate resistance mechanisms of C. sumatrensis.

Validation and Application of Liquid Chromatography Coupled with Tandem Mass Spectrometry Method for the Analysis of Glyphosate, Aminomethylphosphonic Acid (AMPA), and Glufosinate in Soil

Agriculture, 2023
A method was developed to determine glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate in soil. The worldwide use of this herbicide in agricultural activities, and its known negative effects on both the environment and health, have generated ...

Non-Target Site Mechanisms Endow Resistance to Glyphosate in Saltmarsh Aster (Aster squamatus)

Plants, 2021
Of the six-glyphosate resistant weed species reported in Mexico, five were found in citrus groves. Here, the glyphosate susceptibility level and resistance mechanisms were evaluated in saltmarsh aster (Aster squamatus), a weed that also occurs in Mexican

Cbz-aminomethylphosphonic acid and its structural variations: synthesis from a common precursor and a stability study

ARKIVOC, 2011
Cbz-aminomethylphosphonic acid as well as its P=S, P=Se and P-BH3 analogs were synthesized using DMSO/I2 and a three-step, one-pot procedure respectively. In all cases the corresponding Cbz-aminomethylphosphinic acid was the starting material. The latter

Synthesis of Graphene Oxide and Functionalized Graphene Oxide Using Improved Hummers Method for the Adsorption of Lead from Aqueous Solutions [PDF]

آب و فاضلاب, 2021
One of the most important environmental challenges in the world is environmental pollution with toxic and dangerous heavy metals, which causes various environmental effects. Lead is a heavy metal that can be removed in a variety of methods. In this study,

Surface Plasmon Resonance Imaging Sensor for Detection of Photolytically and Photocatalytically Degraded Glyphosate

Sensors, 2022
Glyphosate is one of the most widely used pesticides, which, together with its primary metabolite aminomethylphosphonic acid, remains present in the environment. Many technologies have been developed to reduce glyphosate amounts in water.

Glyphosate and aminomethylphosphonic acid are not detectable in human milk [PDF]

The American Journal of Clinical Nutrition, 2016
Although animal studies have shown that exposure to glyphosate (a commonly used herbicide) does not result in glyphosate bioaccumulation in tissues, to our knowledge there are no published data on whether it is detectable in human milk and therefore consumed by breastfed infants.We sought to determine whether glyphosate and its metabolite ...
