natriuresis

 [na″tre-u-re´sis]
the excretion of sodium in the urine; see also salt wasting and salt-losing crisis (syndrome).

na·tri·u·re·sis

(nā'trē-yū-rē'sis),
Urinary excretion of sodium; commonly designates enhanced sodium excretion, which may occur in certain diseases or as a result of the administration of diuretic drugs.
[natrium + G. ouron, urine]

natriuresis

/na·tri·ure·sis/ (na″tre-ūr-e´sis) excretion of sodium in the urine, particularly in excessive amounts.
pressure natriuresis  increased urinary excretion of sodium along with water when arterial pressure increases; a compensatory mechanism to maintain blood pressure within the normal range.

natriuresis

(nā′trə-yo͝o-rē′sĭs)
n.
Excretion of excessive amounts of sodium in the urine.

na′tri·u·ret′ic (-rĕt′ĭk) adj.

natriuresis

[nā′trēyoo͡rē′sis]
Etymology: L, natrium, sodium; Gk, ouresis, urination
the excretion of greater than normal amounts of sodium in the urine. The condition may result from the administration of natriuretic diuretic drugs or from various metabolic or endocrine disorders.

natriuresis

The excretion of sodium by the kidneys, which is controlled in large part by atrial natriuretic peptide (ANP). ANP may increase the glomerular filtration rate by binding to ANP receptors on glomerular mesangial cells, causing them to relax, thereby increasing the effective surface area available for filtration.

(nā'trē-yū-rē'sis)
Urinary excretion of sodium; commonly designates enhanced sodium excretion, which may occur in certain diseases or as a result of the administration of diuretic drugs.

natriuresis

Excretion of sodium by the kidneys.

natriuresis (nāˈ·tr·yōō·rēˑ·sis),

n the secretion of increased amounts of sodium in urine. It may be due to endocrine or metabolic conditions, or due to the use of natriuretic diuretic medications.

natriuresis

the excretion of abnormal amounts of sodium in the urine.

Several studies have demonstrated that the slope of the normal chronic salt-loading pressure natriuresis curve is very steep.
However, chronic high caffeine ingestion is associated with central nervous system, cardiovascular, gastrointestinal, and renal dysfunction, as such ingestion promotes diuresis and natriuresis, reduces insulin sensitivity, increases blood pressure, leads to chronic daily headaches, and can even lead to death (15).
CSWS is excess natriuresis and dehydration noted in subjects suffering from subarachnoid hemorrhage and brain injury, however, it is rare after pituitary tumor surgery (13).

Renal dose dopamine (2-3pg/ kg/min) acts through dopaminergic receptors and results in diuresis, natriuresis, increase in renal blood flow and glomerular filtration rate (18).
NEP is the major enzymatic pathway of degradation of natriuretic peptides, which are thought to have such beneficial effects in hypertension as vasodilation, natriuresis, and inhibition of the sympathetic nervous system.
The decrease in plasma sodium can be attributed to progesterone-enhanced natriuresis during the luteal phase (17), as progesterone is a competitive antagonist to aldosterone (18).
The spironolactone aids by blocking sodium reabsorption at the distal tubule, which allows natriuresis or sodium loss.
A traves del receptor ETA de la endotelina 1 se genera el mas potente efecto vasoconstrictor; sin embargo, la endotelina 1 ejerce un mecanismo contraregulador al estimular el receptor ETB que estimula la produccion de ON y prostanglandina E2 lo que genera relajacion vascular, diuresis y natriuresis (43, 44).
Natriuresis excludes dehydration from salt loss during sweating as a primary mechanism, which circumstance would result in low urine [Na+] due in part to increased renal sodium reabsorption from activation of the reninangiotensin-aldosterone system.
