STUDIES OF UREA EXCRETION. II: Relationship Between Urine Volume and the Rate of Urea Excretion by Normal Adults.

Journal of Clinical Investigation, 1928
Investigations by Marshall and Davis (1914), Pepper and Austin (1915), Addis and Watanabe (1916), and by Addis, Barnett, and Shevky (1918) have shown that when the urine volume is fairly large the rate of urea excretion is directly proportional to the ...

Fatal and nonfatal outcomes, incidence of hypertension, and blood pressure changes in relation to urinary sodium excretion.

Journal of the American Medical Association (JAMA), 2011
CONTEXT Extrapolations from observational studies and short-term intervention trials suggest that population-wide moderation of salt intake might reduce cardiovascular events.

Genetics of residual feed intake in growing pigs: Relationships with production traits, and nitrogen and phosphorus excretion traits.

Journal of Animal Science, 2013
Residual feed intake (RFI) is defined as the difference between the observed ADFI and the ADFI predicted from production and maintenance requirements. The objectives of this study were to evaluate RFI as a selection criterion to improve feed efficiency ...

Prediction of urinary nitrogen and urinary urea nitrogen excretion by lactating dairy cattle in northwestern Europe and North America: a meta-analysis.

Journal of Dairy Science, 2013
A meta-analysis was conducted on the effect of dietary and animal factors on the excretion of total urinary nitrogen (UN) and urinary urea nitrogen (UUN) in lactating dairy cattle in North America (NA) and northwestern Europe (EU).

Ammonia Production, Excretion, Toxicity, and Defense in Fish: A Review

Front. Physiology, 2010
Many fishes are ammonotelic but some species can detoxify ammonia to glutamine or urea. Certain fish species can accumulate high levels of ammonia in the brain or defense against ammonia toxicity by enhancing the effectiveness of ammonia excretion ...

Neurosecretion and sodium excretion

Kidney International, 1974
Over the last few years there has been an accumulation of observations which indicate that there is a humoral substance other than aldosterone which influences renal sodium excretion. The findings by numerous authors have demonstrated that this humoral factor increases the excretion of sodium in response to expansion of the extracellular fluid (ECF ...

Effect of replacing alfalfa silage with high moisture corn on ruminal protein synthesis estimated from excretion of total purine derivatives.

Journal of Dairy Science, 1999
Twenty-four multiparous dairy cows (eight with ruminal cannulae) were blocked by days in milk and assigned to six balanced 4 x 4 Latin squares with 21-d periods.
