Frontiers in Physiology, 2012 Uncontrolled diabetes mellitus results in osmotic diuresis. Diabetic patients have lowered nitric oxide (NO) which may exacerbate polyuria. We examined how lack of NO affects the transporters involved in urine concentration in diabetic animals ...

The role of rumen epithelial urea transport proteins in urea nitrogen salvage: A review
Animal Nutrition, 2022 The symbiotic relationship between the host and the rumen microbiome plays a crucial role in ruminant physiology. One of the most important processes enabling this relationship is urea nitrogen salvaging (UNS).

Investigation of facilitative urea transporters in the human gastrointestinal tract
Physiological Reports, 2018 The symbiotic relationship between humans and their intestinal microbiome is supported by urea nitrogen salvaging. Previous studies have shown that colonic UT‐B urea transporters play a significant role in this important physiological process.

Regional investigation of UT-B urea transporters in the rat brain
Biochemistry and Biophysics Reports, 2023 Recent studies have reported increased levels of urea in the aging brain and various neurological disorders. Additionally, these diseased tissues also have increased expression of the UT-B transporter that regulates urea transport in the brain.

Modelling and mutational analysis of Aspergillus nidulans UreA, a member of the subfamily of urea/H+ transporters in fungi and plants [PDF]
Open Biology, 2014 We present the first account of the structure–function relationships of a protein of the subfamily of urea/H+ membrane transporters of fungi and plants, using Aspergillus nidulans UreA as a study model.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Measurement of Net High-affinity Urea Uptake in Maize Plants
Bio-Protocol, 2015 Despite its extensive use as a nitrogen fertilizer, the role of urea as a directly accessible nitrogen source for crop plants is still poorly understood. So far, the physiological and molecular aspects of urea acquisition have been investigated only in a

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Urea transport in Saccharomyces cerevisiae [PDF]
Journal of Bacteriology, 1975 Urea transport in Saccharomyces cerevisiae occurs by two pathways. The first mode of uptake is via an active transport system which: (i) has an apparent Km value of 14 muM, (ii) is absolutely dependent upon energy metabolism, (iii) requires pre-growth of the cultures in the presence of oxaluric acid, gratuitous inducer of the allantoin degradative ...
