However...

...Jianwei Xu; Xiaorong Chen; Zeng Ge; Hao Liang; Liuxia Yan; Xiaolei Guo; Yongqing Zhang; Linhong Wang; Jixiang Ma Background/Aims: High sodium intake and low intake of potassium can increase blood pressure (BP) and risk of developing hypertension. Few studies have examined the association between 24...

Methods: A total of 334 subjects from 124 families were recruited from the rural areas of northern China. After a three-day baseline observation, they were sequentially maintained...

... variations in the gene with RNLS are associated with hypertension. The aim of this study was to examine the association between genetic variants in RNLS and blood pressure (BP) responses to strict dietary interventions of salt and potassium intake. Methods: A total of 334 subjects from 124 families were...

... in a relatively short period of time. The dialysate content of bicarbonate (DBic) and potassium (DK) may have impact over intradialytic hemodynamics, which goes beyond ultrafiltration, and its impact was evaluated in a prospective cohort. Methods: 30 patients under HD were submitted to hemodynamic assessment (HA...

The observations may point to parallel loss of potassium through potassium channels as well as of bicarbonate and sodium via a bicarbonate-sodium cotransport. Alternatively, potassium/hydrogen ion...
