It has been well established that the circadian clock plays a crucial role in the regulation of
almost every physiological process. It also plays a critical role in pathophysiological states …

This article summarizes current data and approaches to assess sodium intake in individuals
and populations. A review of the literature on sodium excretion and intake estimation …

In addition to its widely contested influence on arterial pressure, dietary sodium may exert
some nonpressure-related effects on left ventricular mass in humans. In the present study …

Blood pressure (BP) follows a circadian rhythm, with 10% to 15% lower values during
nighttime than during daytime. The absence of a nocturnal BP decrease (dipping) is …

More than 30 years ago, Guyton1 described pressure-natriuresis: increasing arterial blood
pressure promotes sodium excretion, decreasing blood volume and lowering blood …

Restriction of dietary salt is widely recommended in the management of hypertension, but
assessment of individual salt intake has drawn little attention. The understanding of salt …

Objective: The relationships between blood pressure and the urinary excretion rates of
sodium and potassium during the day and at night were investigated. Methods: A total of 160 …

While sodium and potassium are individually important for blood pressure (BP) regulation,
the relative contribution of sodium to potassium intake has not been sufficiently investigated …

Low-sodium and high-potassium diets have been recommended as an adjunct to prevention
and treatment of hypertension. Analysis of these nutrients in 24-h urine has been considered …

Nocturnal polyuria is common in the elderly. In this condition the normal circadian rhythm of
urine production is reversed so that urine flow is higher at night than during the day. Elderly …
