1.1 This Memorandum of Understanding (MOU) sets forth the terms and understanding between the (PMRA) and the (CFIA) on the regulation of nitrogen stabilizers in Canada. 2.1 Nitrification and urease ...

Background: Nephrotoxicity refers to the toxigenic impact of compounds and medications on kidney function. There are a variety of drug formulations, and some medicines that may affect renal function ...

Several enzymes catalyze much of the processes that exist in the soil. Enzymes in polluted soils are usually less active due to their exposure to heavy metals. The main goal of this study was to see ...

Surface-bound enzymes act as pumps in the presence of their specific substrates or promoters, thereby combining sensing and fluidic pumping into a single self-powered microdevice. Using a combination ...

While urea has long been recognized as an important form of nitrogen in planktonic ecosystems, very little is known about how many or which phytoplankton and bacteria can use urea as a nitrogen source ...

We present a high-level quantum chemical study of possible elimination reaction mechanisms associated with the catalytic decomposition of urea at the binuclear nickel active site cluster of urease.

Most members of the genus Brucella show strong urease activity. However, the role of this enzyme in the pathogenesis of Brucella infections is poorly understood. We isolated several Tn5 insertion ...
