Potentiometric urea biosensors
Clinica Chimica Acta, 2022 Excess nitrogen in the body is converted to urea in the liver, and urea is disposed as a waste product in urine. Urea concentration can change in body fluids such as blood due to the presence of certain disorders. Therefore, the determination of urea is of high importance in various areas including medical diagnosis, as well as food quality control and

Molecular Genetics and Metabolism Reports, 2021 Pathogenic variants in non-coding regions of genes encoding enzymes or transporters of the urea cycle can lead to urea cycle disorders (UCDs). However, not all commercially available testing platforms interrogate these regions. Here, we used a gene panel

Denaturing Urea Polyacrylamide Gel Electrophoresis (Urea PAGE) [PDF]
Journal of Visualized Experiments, 2009 Urea PAGE or denaturing urea polyacrylamide gel electrophoresis employs 6-8 M urea, which denatures secondary DNA or RNA structures and is used for their separation in a polyacrylamide gel matrix based on the molecular weight. Fragments between 2 to 500 bases, with length differences as small as a single nucleotide, can be separated using this method(1)

Aqueous Urea Solutions: Structure, Energetics, and Urea Aggregation [PDF]
The Journal of Physical Chemistry B, 2007 Urea is ubiquitously used as a protein denaturant. To study the structure and energetics of aqueous urea solutions, we have carried out molecular dynamics simulations for a wide range of urea concentrations and temperatures. The hydrogen bonds between urea and water were found to be significantly weaker than those between water molecules, which drives ...

Short-term nitrous oxide emissions from pasture soil as influenced by urea level and soil nitrate [PDF]
, 2004 Nitrogen excreted by cattle during grazing is a significant source of atmospheric nitrous oxide (N2O). The regulation of N2O emissions is not well understood, but may vary with urine composition and soil conditions.

Reduction of nitrogen oxides by injection of urea in the freeboard of a pilot scale fluidized bed combustor [PDF]
, 1989 The ‘thermal deNOx’ process using urea has been investigated in a 1 MW fluidized bed combustor. NOx reductions of up to 76% were obtainable by using this method. The experimental results show that urea is at least as active as NH3, which is commonly used
