OBJECTIVES: To evaluate the effect of potassium-sodium citrate on the development of computed tomography-detected renal microcalculi into symptomatic stones in calcium stone-forming patients. METHODS: Patients (aged 20-80 years) with history of calcium component stones who visited Nagoya City Hospital, Nagoya, Aichi, Japan, between April 2009 and June 2014 were included. They were retrospectively divided into those who did not receive potassium-sodium citrate (non-citrate group, n = 157) and those who did (citrate group, n = 60)...

A few epidemiological data are available assessing the associations of intakes of sodium (Na) and potassium (K) with non-alcoholic fatty liver disease (NAFLD). We aimed to examine the associations of dietary intake of Na and K with the prevalence of ultrasound-diagnosed NAFLD. We performed a cross-sectional study of 100 177 participants (46 596 men and 53 581 women) who underwent a health screening examination and completed a FFQ at the Kangbuk Samsung Hospital Total Healthcare Centers, South Korea, between 2011 and 2013...

This paper presents the results of the application of the advanced LBET and QSDFT methods compared to the BET and DR approach to the comprehensive analysis of the porous structure of activated carbons obtained by chemical activation of demineralised Kraft lignin with potassium and sodium hydroxides. Based on the analysis of nitrogen adsorption isotherms, the influence of the preparation process conditions on the porous structure formation was investigated. Particularly, the impact of the type of activating agent, the activation temperature, the hydroxide to lignin mass ratio, and the flow rate of inert gas on the porous structure formation was assessed...

Limited number of studies on salt intake has been conducted in the South Africa. The present study established the sodium and potassium excretion (24-hour urine collection) of three different South African populations. In total, 692 successful 24-hour urine collections were analyzed for sodium, potassium, and iodine levels. The median sodium and potassium excretion was 122.9 and 33.5 mmol/d, respectively, and the median salt intake was 7.2 g/d. The majority (92.8%) of the population did not meet the recommended potassium intake/d, and 65...

OBJECTIVE: The aim of this study was to examine the relationship between sodium and potassium intakes and blood pressure (BP) in a clinical sample. METHODS: Secondary analysis of baseline data from 328 participants (mean age: 43.6 ± 8 y, mean body mass index [BMI]: 32.4 ± 4.2 kg/m(2), mean systolic BP [SBP]/diastolic BP [DBP]: 124.9 ± 14.5/73.3 ± 9.9 mm Hg) of the 12-mo HealthTrack randomized controlled weight loss trial was conducted. Resting BP and 24-h urine sodium and potassium were measured...

BACKGROUND: The relationship between lower sodium intake and total mortality remains controversial. OBJECTIVES: This study examined the relationship between well-characterized measures of sodium intake estimated from urinary sodium excretion and long-term mortality. METHODS: Two trials, phase I (1987 to 1990), over 18 months, and phase II (1990 to 1995), over 36 months, were undertaken in TOHP (Trials of Hypertension Prevention), which implemented sodium reduction interventions...

Limited studies have examined the association between sodium (Na) and potassium (K) levels and the risk of atherosclerosis. This study examined whether higher Na and Na/K levels and low K levels were independent risk factors for atherosclerosis. This community-based cross-sectional study included 3290 subjects (1067 men and 2223 women) 40 to 75 years of age in Guangzhou, China, between 2011 and 2013. Urinary excretion of Na and K were measured from the first morning void, and creatinine-adjusted values were used...

BACKGROUND AND OBJECTIVES: Albuminuria is a risk factor for cardiovascular and renal disease. However, little is known about the association of 24 h urinary sodium and potassium excretion with albuminuria in China. The aim of this study was to examine this association by analyzing the data from 1,975 Chinese adults living in north China. METHODS AND STUDY DESIGN: Excretion of urinary sodium, potassium and albumin was assessed in a single 24-h urine sample for each participant...

Renal sympathetic nerve activity has an important role in renal disease-associated hypertension and in the modulation of fluid homeostasis. In the present study, changes in renal function and renal sodium/potassium handling were investigated in groups of 12-week-old male, spontaneously hypertensive rats with renal denervation (RDNX group) or sham denervation (sham group). The RDNX group excreted significantly more sodium than the sham group during the 2-week observation period (P<0.05). Following bilateral renal denervation, the fractional lithium excretion was elevated in the RDNX group compared with the sham group, but no significant effect was observed of renal denervation on the fractional distal reabsorption rate of sodium or the fractional excretion of potassium...

To separate proteins solely based on their difference in hydrodynamic volume in size exclusion chromatography (SEC), the ionic strength of the mobile phase has to be increased in order to avoid secondary ionic interactions between proteins and the stationary phase. However, adding salts to the mobile phase can have a serious effect on protein aggregation and can lead to artifacts. In the present study, several monoclonal antibodies (mAbs) and the antibody-drug conjugate (ADC), trastuzumab emtansine were selected to study the effect of mobile phase salt additive on aggregation measurements...

BACKGROUND: Salinity is one of the many abiotic stresses limiting rice production worldwide. Several studies were conducted to identify quantitative trait loci (QTLs) for traits associated to salinity tolerance. However, due to large confidence interval for the position of QTLs, utility of reported QTLs and the associated markers has been limited in rice breeding programs. The main objective of this study is to construct a high-density rice genetic map for identification QTLs and candidate genes for salinity tolerance at seedling stage...

We investigated the ion transport mechanism (ITM) in renal cell cancer (RCC) etiology using gene-environment interactions between candidate single nucleotide polymorphisms (SNPs) and associated environmental factors, including dietary intakes of sodium, potassium and fluid, hypertension and diuretic medication. A literature-based selection of 13 SNPs in ten ITM genes were successfully genotyped in toenail DNA of 3,048 subcohort members and 419 RCC cases from the Netherlands Cohort Study. Diet and lifestyle were measured with baseline questionnaires...

AIMS: The vasopressin V2 receptor antagonist tolvaptan has been used for the treatment of cirrhotic patients with ascites; however, no predictor of efficacy and prognosis has been developed. Here, we evaluated candidate predictors of response to tolvaptan treatment. METHODS: This was a single-center retrospective study. Overall, 97 Japanese cirrhotic patients (60 males, median age 63 years), who were hospitalized for ascites treatment including oral tolvaptan coupled with conventional diuretics, were enrolled...

BACKGROUND: Dietary pattern analysis provides important evidence revealing diet-disease relationships. It may be especially useful in areas less well researched, such as diet and hypertension in clinical populations. OBJECTIVE: The aim of this study was to identify the association between dietary patterns and blood pressure (BP) in a sample of overweight adults volunteering for a clinical trial for weight loss. DESIGN: This cross-sectional analysis used baseline data from the HealthTrack study, a 12-month randomized controlled trial...

Arsenic is a groundwater pollutant and can cause various cardiovascular disorders in the exposed population. The aim of the present study was to assess whether subchronic arsenic exposure through drinking water can induce vascular dysfunction associated with alteration in plasma electrolytes and lipid profile. Rats were exposed to arsenic as 25, 50, and 100 ppm of sodium arsenite through drinking water for 90 consecutive days. On the 91st day, rats were sacrificed and blood was collected. Lipid profile and the levels of electrolytes (sodium, potassium, and chloride) were assessed in plasma...

BACKGROUND: Distal tubular sodium retention is a potent driver of hypertension, with the thiazide sensitive sodium-chloride cotransporter (NCC) a key player. The upstream modulators of NCC are unclear, but recent evidence has revealed the kinases 'with-no-lysine kinase 4' (WNK4) and 'STE20/SPS1-related, proline alanine-rich kinase' (SPAK) to be involved. The wider role of mineralocorticoids is poorly understood, but animal models implicate aldosterone as a potent regulator, possibly via effects on plasma potassium...
