BACKGROUND: Sodium lactate has been shown to improve hemodynamics and avoid fluid overload. The objective of this study was to confirm a beneficial effect on fluid balance with sodium lactate infusion and to specify whether the advantage of lactate is related to a negative chloride balance, its particular metabolism, or simply its energy load. METHODS: This was an interventional, randomized, open-label, controlled experimental study. Fifteen female "large white" pigs (2 months old) were challenged with intravenous infusion of Escherichia coli endotoxin...

Current receptor-binding assays for dopamine do not measure the in vitro whole cellular response against dopamine or potential agonist/antagonist molecules. We herewith report the development of a novel functional assay concept for studying the in vitro interaction of the neurotransmitter dopamine with neural cells bearing dopamine receptors. The concept is based on the ultra-rapid measurement of changes in the electric properties of cultured N2a mouse neuroblastoma cells (corresponding to cumulative changes of the cell membrane potential)...

AIMS: Sodium nitrite is a widely used color fixative and preservative. However, it has been reported to exert deleterious toxic effects on various body organs. Moreover, thymoquinone (TQ), the active constituent of Nigella sativa oil is known to possess beneficial antioxidant and anti-inflammatory effects. The present study was conducted to evaluate the potential protective effects of TQ against sodium nitrite-induced renal toxicity. MAIN METHODS: Male Sprague-Dawley rats were treated with sodium nitrite (80mg/kg, po, daily) in presence or absence of TQ (25 and 50mg/kg, po, daily)...

During sepsis, excessive activation of the complement system with generation of the anaphylatoxin C5a results in profound disturbances in crucial neutrophil functions. Moreover, because neutrophil activity is highly dependent on intracellular pH (pHi), we propose a direct mechanistic link between complement activation and neutrophil pHi In this article, we demonstrate that in vitro exposure of human neutrophils to C5a significantly increased pHi by selective activation of the sodium/hydrogen exchanger. Upstream signaling of C5a-mediated intracellular alkalinization was dependent on C5aR1, intracellular calcium, protein kinase C, and calmodulin, and downstream signaling regulated the release of antibacterial myeloperoxidase and lactoferrin...

BACKGROUND: Pouchitis occurs in approximately 50% of patients with ulcerative colitis after ileal pouch-anal anastomosis (IPAA) but the pathogenesis remains unclear. We used a rat model of dextran sulfate sodium (DSS)-induced ileal pouchitis to examine whether intestinal barrier disruption plays a role in the development and progression of the disease. METHODS: Rats were randomly divided into DSS (underwent IPAA and administered 5% DSS orally), IPAA (underwent IPAA), and Sham groups (underwent switch abdominal surgery)...

Both high sodium and low potassium diets are associated with hypertension, but whether these risk factors are distinct or overlapping has not been thoroughly investigated. The authors evaluated the relationship between dietary sodium, potassium, and high systolic blood pressure among 4716 adolescents aged 12 to 14 years who participated in the National Health and Nutrition Examination Survey from 1999 to 2012. There was no association with blood pressure across most values of sodium or potassium intake. However, participants who reported sodium intake ≥7500 mg/d, potassium <700 mg/d, or sodium-potassium ratio ≥2...

Graphene produced by chemical vapor deposition (CVD) is a promising candidate for implementing graphene in a range of technologies. In most device configurations, one side of the graphene is supported by a solid substrate, wheras the other side is in contact with a medium of interest, such as a liquid or other two-dimensional material within a van der Waals stack. In such devices, graphene interacts on both faces via noncovalent interactions and therefore surface energies are key parameters for device fabrication and operation...

Renal diets for advanced chronic kidney disease (CKD) are structured to achieve a lower protein, phosphate and sodium intake, while supplying adequate energy. The aim of this nutritional intervention is to prevent or correct signs, symptoms and complications of renal insufficiency, delaying the start of dialysis and preserving nutritional status. This paper focuses on three additional aspects of renal diets that can play an important role in the management of CKD patients: the vitamin K1 and fiber content, and the alkalizing potential...

Diabetic kidney disease is among the most frequent complications of diabetes, with approximately 50% of patients with ESRD attributed to diabetes in developed countries. Although intensive glycemic management has been shown to delay the onset and progression of increased urinary albumin excretion and reduced GFR in patients with diabetes, conservative dose selection and adjustment of antihyperglycemic medications are necessary to balance glycemic control with safety. A growing body of literature is providing valuable insight into the cardiovascular and renal safety and efficacy of newer antihyperglycemic medications in the dipeptidyl peptidase-4 inhibitor, glucagon-like peptide-1 receptor agonist, and sodium-glucose cotransporter 2 inhibitor classes of medications...

Cristian P Schulthess, Udonna Ndu
Simultaneous adsorption modeling of four ions was predicted with a strict net charge-neutral ion-exchange theory and its corresponding equilibrium and mass balance equations. An important key to the success of this approach was the proper collection of all the data, particularly the proton adsorption data, and the inclusion of variable concentrations of conjugate ions from the experimental pH adjustments. Using IExFit software, the ion-exchange model used here predicted the competitive retention of several ions on goethite by assuming that the co-adsorption or desorption of all ions occurred in the correct stoichiometries needed to maintain electroneutrality...

Carlos M Farinha, Paulo Matos
The amount of ion channels and transporters present at the plasma membrane is a crucial component of the overall regulation of ion transport. The number of channels present result from an intricate network of proteins that controls the late events of channel trafficking, such as endocytosis, recycling and targeting to lysosomal degradation. Small GTPases of the Rab family are key players in these processes thus contributing to regulation of fluid secretion and ion homeostasis. In epithelia, this involves mainly the balance between the chloride channel CFTR and the sodium channel ENaC, whose misfunction is a hallmark of cystic fibrosis - the commonest recessive disorder in Caucasians...

Certain stimuli at the gut barrier may be necessary in early life to establish a proper balance of immune tolerance. We evaluated a compromised barrier in juvenile mice in relation to microbiota and local and systemic immunity. BALB/c mice were treated with a low dose of dextran sulfate sodium (DSS) with or without ampicillin and lipopolysaccharide (LPS) to clarify the importance of microbial antigens and interaction between microbial-associated patterns and toll-like receptors. The barrier breach resulted in increased plasma LPS, which was highest in mice treated simultaneously with ampicillin...

The respiratory epithelium is lined by a tightly balanced fluid layer that allows normal O2 and CO2 exchange and maintains surface tension and host defense. To maintain alveolar fluid homeostasis, both the integrity of the alveolar-capillary barrier and the expression of epithelial ion channels and pumps are necessary to establish a vectorial ion gradient. However, during pulmonary infection, auto- and/or paracrine-acting mediators induce pathophysiological changes of the alveolar-capillary barrier, altered expression of epithelial Na,K-ATPase and of epithelial ion channels including epithelial sodium channel and cystic fibrosis membrane conductance regulator, leading to the accumulation of edema and impaired alveolar fluid clearance...

Eimeria tenella, one of the most important parasitic protozoa in the genus Eimeria, is responsible for chicken caecal coccidiosis resulting in huge economic losses to poultry industry. The present study investigated the changes in caecal microflora of E. tenella-infected chickens and the regulating effect of coated sodium butyrate, a potential alternative to antibiotics. Using high-throughput sequencing of 16S rRNA V3-V4 region of bacteria we found significant changes in caecal microflora of E. tenella-infected chickens indicated by an increase of Firmicutes (mainly Ruminococcaceae, Lachnospiraceae and vadin BB60) and Proteobacteria (mainly Enterobacteriaceae) and a decrease of Bacteroidetes (predominantly Bacteroidaceae)...
