Movement of NH3 through the human urea transporter B: a new gas channel
(American Physiological SocietyBethesda, 2013-06-15)
Aquaporins and Rh proteins can function as gas (CO2 and NH3) channels. The present study explores the urea, H2O, CO2, and NH3 permeability of the human urea transporter B (UT-B) (SLC14A1), expressed in Xenopus oocytes. We ...
The urea transporter DUR3 is differentially regulated by abiotic and biotic stresses in coffee plants
(2021-02-01)
The high costs of N fertilizers in the coffee production emphasizes the need to optimize fertilization practices and improve nitrogen use efficiency. Urea is widespread in nature, characterizing itself as a significant ...
PKC stimulated by glucagon decreases UT-A1 urea transporter expression in rat IMCD
(SPRINGER, 2008)
It is well-known that glucagon increases fractional excretion of urea in rats after a protein intravenous infusion. This effect was investigated by using: (a) in vitro microperfusion technique to measure [(14)C]-urea ...
Modeling fate and transport of ammonium, nitrite, and nitrate in a soil contaminated with large dose of urea
(Springer, 2021-08-14)
Soil or groundwater potential contamination generated by urea spills during its manufacture process is unknown. The aim of this work is determining the fate and transport of Nitrogen (N) species (ammonia, nitrites, and ...
Torrefied banana tree fiber pellets having embedded urea for agricultural use
(2018-01-01)
Banana tree fibers (BF) torrefied in the absence of air and residence time of 60 min at temperatures between 180 and 600 ∘C were evaluated for its agglutination power when converted to pellets. The agglutination power was ...
AtTIP1;3 and AtTIP5;1, the only highly expressed Arabidopsis pollen-specific aquaporins, transport water and urea
(Elsevier Science, 2008-12)
Pollination includes processes where water and/or solute movements must be finely regulated, suggesting participation of aquaporins. Using information available from different transcriptional profilings of Arabidopsis ...
Production of granular urea as nitrogen fertilizer
(Nova Science Publishers, 2014)
The demand for urea is continuously growing and entwined with the need for fertilizers and animal feed additives. Industrially, urea is initially produced in liquid form as a concentrated solution. Then, it can be converted ...
