Characterization of sodium transport at the plasma membrane of Spergularia marina
Plants vary in their whole plant strategies for managing the sodium (Na$\sp{+}$) present in their environment, but current models predict that they have a common strategy at the cellular level: exclusion from the cytoplasm. This entails either passive exclusion mediated by low plasma membrane …

Hair Na and K Concentration is Related with the Risk of Coronary Artery Disease in Korean Men
Imbalance in mineral metabolism, particularly sodium (Na) and potassium (K), is associated with increased risk of coronary artery disease (CAD). There has been no previous study to elucidate the relationship using hair mineral concentration which is a better reflection of body mineral content …

The effect of an aerobic exercise program and two hypocaloric diets of different carbohydrate content on blood pressure and sodium balance in obese females
… concommitant with an aerobic exercise program on sodium (Na) balance and blood pressure changes. Subjects participated three times a week in a submaximal periodic exercise session and were placed on one of the diets for 28 days. Posttreatment, each participant consumed a 1000 kcal mixed diet while …
