CYANATE AS A HEMOLYTIC FACTOR [PDF]
Renal Failure, 2000 During advanced renal failure, and particularly in patients with end-stage renal disease, proteins are carbamylated as a result of a reaction with cyanate. If the carbamylation of proteins adversely alters their biologic activities and structures, then urea must be viewed as an uremic toxin, rather than a surrogate.

Biochemical and structural properties of cyanases from Arabidopsis thaliana and Oryza sativa. [PDF]
PLoS ONE, 2011 Cyanate is toxic to all organisms. Cyanase converts cyanate to CO₂ and NH₃ in a bicarbonate-dependent reaction. The biophysical functions and biochemical characteristics of plant cyanases are poorly studied, although it has been investigated in a variety

Processing of analogues of plume fallout in cold regions of Enceladus by energetic electrons [PDF]
A&A 570, A120 (2014), 2014 Enceladus, a small icy moon of Saturn, is one of the most remarkable bodies in the solar system. This moon is a geologically active object, and despite the lower temperatures on most of its surface, the geothermally heated south polar region presents geysers that spouts a plume made of water (approximately ninety percent), carbon dioxide, methane ...

Urea Complete Conversion to Compound Fertilizer in Industrial‐Scale Tandem Reactors
Angewandte Chemie, Volume 137, Issue 16, April 11, 2025.An industrial‐grade tandem system was developed to fully convert urea (or urea wastewater) into compound fertilizer while generating H2. In a typical cycle, 200 g of urea was used to produce 232 L of pure H2 and 1580 g of solid compound fertilizer (KH2PO4 and NH4H2PO4) without further separation. The core is to develop an electrocatalyst (S‐NiOOH‐Ni(OH)

Estimating the level of carbamoylated plasma non-high-density lipoproteins using infrared spectroscopy [PDF]
, 2019 Background: The increased cardiovascular morbidity and mortality observed in chronic kidney disease (CKD) patients can be partly explained by the presence of carbamoylated lipoproteins. Lipid profiles can be determined with infrared spectroscopy. In this
