Salicylic acid (SA) is a phyto-hormone that regulates physiological and biological processes in plants and can be used to improve plant growth under different environmental conditions, including water stress. Thus, a field experiment as split plot factorial based on randomized complete blocks design with three replications was conducted in 2014 to investigate the effects of fertilizer and salic...

The chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (DM) and crude protein (CP) were evaluated for olive cake (OC)silages treated (DM basis) with additives as follows: (1) untreated OC, (2) OC + 0.5% urea, (3) OC + 0.4%formic acid, (4) OC + 8% molasses, (5) OC + 0.5% urea + 8% molasses, (6) OC + 0.5% urea + 0.4%...

BACKGROUND We describe online optical measurements of urea in the effluent dialysate line during regular hemodialysis treatment of several patients. Monitoring urea removal can provide valuable information about dialysis efficiency. METHODS Spectral measurements were performed with a Fourier-transform infrared spectrometer equipped with a flow-through cell. Spectra were recorded across the 50...

one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

ROCH-RAMEL, FRANCOISE, J. DI~ZI, FRANGOISE CHOM~TY, PIERRETTE MICHOUD, AND G. PETERS. Disposal of large urea overloads by the rat kidney: a micropuncture study. Am. J. Physiol. 2 1 a(6) : 1524-1532. 1970.-In rats overloaded with urea, at plasma concentrations of 60-80 mM, the proximal fractional reabsorption of urea was not impaired, whereas the cortical tissue-to-plasma urea concentration rati...

The Chinese soft-shelled turtle, Pelodiscus sinensis, is well adapted to aquatic environments, including brackish swamps and marshes. It is ureotelic, and occasionally submerges its head into puddles of water during emersion, presumably for buccopharyngeal respiration. This study was undertaken to test the hypothesis that the buccophyaryngeal cavity constitutes an important excretory route for ...

Australian desert frogs of the genera Neobatrachus, Cyclorana and Heleioporus experience significant dehydration, and iono- and osmoconcentration, during aestivation in the laboratory and accumulate substantial amounts of urea (100-200 mmol)(l-1). We expected a priori that aestivating frogs probably would not need to accumulate balancing osmolytes but would accumulate trimethylamine oxide (TMAO...

Urea is the principal nitrogenous waste product of metabolism and is generated from protein breakdown. It is eliminated from the body almost exclusively by the kidneys in urine, and measurement of its concentration, first in urine and later in blood, has had clinical application in the assessment of kidney (renal) function for well over 150 years. This is the first of two articles that together...
