Ammonium-Enhanced Arsenic Mobilization from Aquifer Sediments

Ammonium-related pathways are important for groundwater arsenic (As) enrichment, especially via microbial Fe­(III) reduction coupled with anaerobic ammonium oxidation; however, the key pathways (and microorganisms) underpinning ammonium-induced Fe­(III ...

Ammonium transporters in grasses : molecular and functional characterization with special reference to the arbuscular mycorrhizal symbiosis [PDF]

, 2013
Most herbaceous plants live in symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungi colonize the roots of their host plant symbionts and provide them with mineral nutrients, especially phosphorus (P) and nitrogen (N) and receive, in exchange ...

Identification of PLK1-PBD Inhibitors from the Library of Marine Natural Products: 3D QSAR Pharmacophore, ADMET, Scaffold Hopping, Molecular Docking, and Molecular Dynamics Study

Marine Drugs
PLK1 is found to be highly expressed in various types of cancers, but the development of inhibitors for it has been slow. Most inhibitors are still in clinical stages, and many lack the necessary selectivity and anti-tumor effects.

Ammonium ion removal from aqueous solutions in the presence of organic compounds, using biochar from banana leaves. Competitive isotherm models

Heliyon
Background: Industrial, e.g. food industrial and domestic wastewaters contain huge amount of compounds causing eutrophication, and should be removed with high cost during wastewater treatment. However, these compounds could be utilized as fertilizers too.
