Osmotic and Nonosmotic Sodium Storage during Acute Hypertonic Sodium Loading.

The Edelman equation has long guided the expected response of plasma [Na+] to changes in sodium, potassium, and water balance, but recent short-term studies challenged its validity. Plasma [Na+] following hypertonic NaCl infusion in individuals on low-sodium diet fell short of the Edelman predictions supposedly because sodium restriction caused progressive osmotic inactivation of 50% of retained sodium. Here, we examine the validity of this challenge.

Concentration and Volume: Understanding Sodium and Water in the Body.

Nurses need to have a firm grasp of normal and pathophysiological mechanisms of sodium and water balance to fully understand assessment findings and establish a rationale for a patient's plan of care. While multiple mechanisms control sodium and water balance, antidiuretic hormone and aldosterone are the most important hormonal influences. This article, the first in a new series designed to improve nurses' understanding of the physiological abnormalities underlying many disorders, reviews the common etiolog...

Sodium toxicity in peritoneal dialysis: mechanisms and "solutions".

The major trials in peritoneal dialysis (PD) have demonstrated that increasing peritoneal clearance of small solutes is not associated with any advantage on survival, whereas sodium and fluid overload heralds higher risk of death and technique failure. On the other hand, higher sodium and fluid overload due to loss of residual kidney function (RKF) and higher transport membrane is associated with poor patient and technique survival. Recent experimental studies also show that, independently from fluid overlo...

Stomach Gastrin is Regulated by Sodium via PPAR-α and Dopamine D1 Receptor.

Gastrin, secreted by stomach G cells in response to ingested sodium, stimulates the renal cholecystokinin B receptor (CCKBR) to increase renal sodium excretion. It is not known, how dietary sodium, independent of food, can increase gastrin secretion in human G cells. However, fenofibrate (FFB), a peroxisome proliferator-activated receptor-α (PPAR-α) agonist, increases gastrin secretion in rodents and several human gastrin-secreting cells, via a gastrin transcriptional promoter. We tested these hypotheses:...

Role of mitochondrial DNA in oxidative damage induced by sodium arsenite in human bronchial epithelial cells.

Long-term exposure to sodium arsenite was found to induce malignant transformation in human bronchial epithelial (HBE) cell line as evidenced by elevated ROS levels. Although chronic sodium arsenite-induced HBE cell line transformation was associated with elevated ROS generation, it was of interest to determine whether acute sodium arsenite exposure also initiated pulmonary damage. Thus, the aim of this study was to investigate oxidative-stress-related pulmonary damage using a human bronchial epithelial (HB...

Dietary sodium and potassium and risk of diabetes: A prospective study using data from the China Health and Nutrition Survey.

- Dietary sodium and potassium intakes are well-known risk factors for cardiovascular outcomes. However, the associations between dietary sodium and potassium and diabetes are still controversial. Our study aimed to examine whether dietary sodium, potassium and the sodium-potassium ratio are associated with the risk of diabetes, based on a large sample of Chinese adults.

Lifespan data on postural balance in multiple standing positions.

Maintaining balance is important throughout life. The Nintendo Wii Balance Board (WBB) can give reliable quantitative measures of postural balance, but reference data are lacking. Furthermore, one-leg standing balance across the adult lifespan is not fully described. The aim of the study was (1) to provide reference data on postural balance in multiple standing positions using a WBB, (2) to determine an age cut-off for the ability to stand on one-leg in men and women.

A total of 15,105 participants were assessed, from 35 to 74 years of age, from a cohort of public employees (ELSA-Brazil). Socioeconomic data were collected with a questionnaire, and 12-hour nighttime urine samples were collected to estimate sodium and potassium intake. Sodium/potassium ratio was calculated in mmol/L and divided into tertiles: 1st tertile, corresponding to "low"; 2nd tertile for "med...

An observational study on intracutaneous sodium storage in intensive care patients and controls.

The development of ICU-acquired sodium disturbances is not fully understood. Alterations in non-osmotic skin sodium storage, hypothetically inflammation-driven, could play a role. To investigate this in critically ill patients we conducted a patient-control study with skin punch biopsies in patients with sepsis (n = 15), after coronary artery bypass grafting (CABG, n = 15) and undergoing total hip arthroplasty (THA-controls, n = 15) respectively, together representing a range in severity of systemic inflamm...

Clinical and neurohumoral associates of variation in plasma sodium in the PREVEND cohort.

Plasma sodium concentration is regulated within narrow limits. Yet, substantial interindividual differences exist even in the normal range. The determinants of these differences are not well understood. We therefore investigated the clinical and neurohumoral associates of plasma sodium. We studied 2364 men (age 48 ± 12 years) and 2710 women (age 47 ± 12 years) from the prospective PREVEND cohort study. In this study, we investigated the neurohumoral factors NT-proBNP and aldosterone as volume markers and ...

Walking meditation promotes ankle proprioception and balance performance among elderly women.

Age-related change of proprioception affects body balance among the elderly. Walking meditation (WM)-a mindfulness practice-involves focusing on leg movements while walking slowly, possibly improving brain processes for perception and balance adjustments. This study investigates the WM's effects on ankle proprioception and balance among the elderly.

Dynamic balance and ankle injury odds: a prospective study in 196 Dutch physical education teacher education students.

The aim of this study was to investigate whether dynamic balance, measured with the anterior component of the Star Excursion Balance Test (SEBT-ANT), is a risk factor for ankle injuries in physical education teacher education (PETE) students.

An analysis of postpartum walking balance and the correlations to anthropometry.

Falls caused by balance issues during pregnancy are quite common, and these issues can continue postpartum, potentially posing a danger to both the mother and baby. While there has been research on changes to walking gait during pregnancy, walking balance in the postpartum period has yet to be examined. Therefore, the aims of this study were to examine if balance changes persist in postpartum and the contribution of anthropometry changes.

Investigation of sodium plating and stripping on a bare current collector with different electrolytes and cycling protocols.

In the present study, stable sodium plating/stripping has been achieved on bare aluminium current collector, without any surface modifications or artificial SEI deposition. The crucial role of pre-deposited sodium using cyclic voltammetry on bare aluminium as a matrix for plating/stripping has been highlighted using different protocols for cycling. The pre-deposition strategy ensures stable and efficient cycling of sodium in anode-free sodium batteries without dendritic formations. The study highlights the ...

24-hour vs Spot Urinary Sodium and Potassium Measurements in Adult Hypertensive patients; A Cohort Validation Study.

Sodium intake is correlated with the development of hypertension. Guyton's principals suggest that the 24-hour urinary sodium excretion reflects sodium ingestion over the same period. 24-hour urine collections are arduous to collect, so many centres use spot urinary measurements instead. We compared spot to matched 24-hour urinary electrolyte measurements.

GLP-1 receptor agonists do not affect sodium intake: Exploratory analyses from two randomized clinical trials.

Excessive sodium intake, despite current dietary advice, remains a global issue with cardiovascular and renal consequences. The aim of this study was to determine whether glucagon-like peptide receptor agonists (GLP-1 RAs), used as antihyperglycemic agents for type 2 diabetes (T2DM) management, may reduce salt cravings as they are known to reduce hedonic feeding behavior and are involved in sodium homeostasis by increasing renal sodium excretion.

A Multiscale Study on the Effect of Sodium Cholate on the Deformation Ability of Elastic Liposomes.

Elastic liposoxy1mes (ELs) are biocompatible bilayer vesicular systems commonly used in the transdermal delivery of drugs. Compared with conventional liposomes (CLs), the strong deformation ability conferred by edge activators (EAs) is one of the most critical properties of ELs. However, due to limited research methods, little is known about the effect of EAs on the deformation abilities of vesicles. In this study, taking sodium cholate as an example, a multiscale study was carried to study the effect of EA...

Controlling the Uncontrollable: Perceptions of Balance in People With Parkinson Disease.

Exercise improves balance in Parkinson disease (PD), yet the majority of people with the diagnosis are physically inactive. Insights gained from understanding how people with PD (PwPD) make sense of their symptoms and their ability to control them may inform the communication strategies and motivational approaches adopted by physical therapists. No previous study has qualitatively explored how PwPD perceive the concept of balance and the beliefs they hold concerning their ability to affect balance.

The application of pulsed electric field as a sodium reducing strategy for meat products.

This study investigated the potential of pulsed electric field (PEF) as a sodium-reduction strategy for processed meat. Beef jerky was used as a model and prepared using different levels of NaCl, viz. 2.0% (control), 1.2% (T) and 1.2% along with PEF processing (T). A significant (p 84% of the panellists preferred T samples over T for saltiness. Results suggest that PEF treatment improved saltiness by influencing the salt diffusion and sodium delivery that led to better perception during chewing. PEF could...

Association of Urinary Plasminogen-Plasmin with Edema and Epithelial Sodium Channel Activation in Patients with Nephrotic Syndrome.

Previous animal experiments and small human studies suggest that urinary plasmin can activate the epithelial sodium channel (ENaC) and contribute to sodium retention in nephrotic syndrome (NS), but this however is not well studied in clinical settings, and its relevance to edema formation is not well characterized in humans. We have investigated the association between urinary plasmin and clinical phenotypes in a large group of patients with NS from multiple etiologies, aiming to assess the role of urinary ...

Toxicological safety assessment of the human-identical milk oligosaccharide 3'-sialyllactose sodium salt.

Human breastmilk is a mixture of nutrients, hormones and bioactive molecules that are vital for infant growth and development. Infant formula (IF) lacks many of these compounds, most notably human milk oligosaccharides (HMOs), which are abundant in breastmilk but scarce in IF. Sialyllactoses, such as 3'-sialyllactose, constitute a large portion of the HMO fraction. To produce IF that matches breastmilk more closely, biosynthesized human-identical milk oligosaccharides (structurally identical to HMOs) such a...

Impact of 3-day high and low dietary sodium intake on sodium status in response to exertional-heat stress: a double-blind randomized control trial.

To determine the impact of altering dietary sodium intake for 3 days preceding exercise on sweat sodium concentration [Na], and cardiovascular and thermoregulatory variables.

Comparing the effect of haptic modalities on walking balance control: Is using one or two arms better?

Adding haptic input by lightly touching a railing or using haptic anchors may improve walking balance control. Typical use of the railing(s) and haptic anchors requires the use of one and two arms in an extended position, respectively. It is unclear whether it is arm configuration and/or the number of arms used or the addition of sensory input that affects walking balance control.
