p53 regulation of ammonia metabolism through urea cycle controls polyamine biosynthesis.
Li L, et al. Nature 2019. PMID 30842655
Here we report that the tumour suppressor p53, the most frequently mutated gene in human tumours, regulates ammonia metabolism by repressing the urea cycle. ...

Determination of urea with special emphasis on biosensors: A review.
Pundir CS, et al. Biosens Bioelectron 2019 - Review. PMID 30308420
Hence, there is an urgent need of determination of urea in biological fluids to diagnose these diseases at their early stage. ...This review presents the principles of various analytical methods for determination of urea with special emphasis on biosensors. ...

Spraying urea solution reduces formaldehyde levels during gross anatomy courses.
Kawata S, et al. Anat Sci Int 2019. PMID 30604187
Among L-cysteine, N-ethyl urea, and urea, the latter was found to have the strongest scavenging power towards the FA in the liquid. The molar concentration of urea that most efficiently reduced the levels of volatilized FA from the wet paper towels was the same as that of the FA. ...

Can urea breath test (UBT) replace rapid urea test (RUT)?
Nawacki Ł, et al. Pol Przegl Chir 2018. PMID 30426947 Free article.
METHODS: The objective of the study was to analyse the clinical and practical value of Carbon-13 urea breath test (UBT) in patients hospitalized due to pain complaints in the upper abdomen and dyspeptic symptoms. ...The urea breath test is a method of high sensitivity and specificity. The positive result of urea breath test may be the basis for the inclusion of eradication therapy....

Salivary creatinine and urea in patients with end-stage chronic kidney disease could not be used as diagnostic biomarkers for the effectiveness of dialysis treatment.
Nogalcheva AN, et al. G Ital Nefrol 2018. PMID 30550042 Free article.
Among the key indicators for tracking patients' current status are urea and creatinine levels. AIM: The study analyzed saliva as a medium to detect and measure urea and creatinine levels in end-stage CKD patients as well as to use it as criteria for the effectiveness of the dialysis treatment by comparing salivary urea and creatinine levels with their blood levels. ...CONCLUSIONS: Despite the parallel increase of the urea and creatinine levels in blood serum and in whole unstimulated saliva in end-stage CKD, salivary urea and creatinine levels could not be used as diagnostic biomarkers for the effectiveness of dialysis treatment....

[Renal physiology of urea transporters].
Li YJ and Yang BX. Sheng Li Xue Bao 2018 - Review. PMID 30560275 Chinese. Free article.
Urea transporters (UTs) are transmembrane urea-selective channel proteins that include two UT subfamilies, UT-A and UT-B. UT-A subfamily includes six members, UT-A1 to UT-A6, which are mainly expressed in kidney. ...

Urea Insertion Reaction of Rhodium-Carbenoid.
Hashimoto Y, et al. Chem Pharm Bull (Tokyo) 2018. PMID 30381656 Free article.
We developed the first carbenoid insertion reaction into the urea C-N bond. The urea insertion reaction proceeded smoothly using Rh(2)(NHPiv)(4), a rhodium catalyst previously designed by our group, to construct a diazabicyclic system. Highly functionalized bridged molecules with three adjacent stereocenters were diastereoselectively synthesized via the urea insertion reaction followed by hydride reduction or nucleophilic addition sequences in one-pot....

The use of urea for the treatment of onychomycosis: a systematic review.
Dars S, et al. J Foot Ankle Res 2019. PMID 31007722 Free PMC article.
Urea is one treatment option, which is thought to improve the efficacy of topical and oral antifungal agents. Despite a theoretical basis for the use of urea for the treatment of onychomycosis, the evidence-base for this treatment has not been systematically reviewed. ...Despite this, a trend was observed to suggest that urea, when added to topical or oral antifungal treatment regimens, improved efficacy of the treatment. ...
