The optimal range of sodium intake for cardiovascular health is controversial. We obtained morning fasting urine samples from 101,945 persons in 17 countries and estimated 24-hour sodium and potassium excretion (used as a surrogate for intake). We examined the association...

The crystal structure of down-regulated NhaA crystallized at acidic pH4 [21] has provided the first structural insights into the antiport mechanism and pH regulation of a Na(+)/H(+) antiporter [22]. On the basis of the NhaA crystal structure [21] and experimental...

G-protein-gated inward rectifier K(+) (GIRK) channels allow neurotransmitters, through G-protein-coupled receptor stimulation, to control cellular electrical excitability. In cardiac and neuronal cells this control regulates heart rate and neural circuit activity, respectively. Here we present the 3.5 Å resolution crystal structure...

Previous prospective cohort studies on the association between potassium intake and risk of hypertension have almost exclusively relied on self-reported dietary data, whereas repeated 24-hour urine excretions, as estimate of dietary uptake, may provide a more objective and quantitative estimate...
