BACKGROUND: Liddle's syndrome is a rare monogenic form of hypertension caused by truncating or missense mutations in the C termini of the epithelial sodium channel (ENaC) β or γ subunits. Patients with this syndrome present with early onset of hypertension, hypokalemia, metabolic alkalosis, hyporeninemia and hypoaldosteronism, and a potassium-sparing diuretics (triamterene or amiloride) can drastically improves the disease condition. Although elderly patients having these characteristics were considered to have Liddle's syndrome or Liddle's-like syndrome, no previous report has indicated that Liddle's-like syndrome could be caused by nephrotic syndrome of primary glomerular disease, which is characterized by urinary excretion of > 3 g of protein/day plus edema and hypoalbuminemia, or has explained how the activity function of ENaC could be affected in the setting of high proteinuria...

Mutation of the gene encoding dystrophin leads to Duchenne and Becker muscular dystrophy (DMD and BMD). Currently, dystrophin is thought to function primarily as a structural protein, connecting the muscle cell actin cytoskeleton to the extra-cellular matrix. In addition to this structural role, dystrophin also plays an important role as a scaffold that organizes an array of signaling proteins including sodium, potassium, and calcium channels, kinases, and nitric oxide synthase (nNOS). Many of these signaling proteins are linked to dystrophin via syntrophin, an adapter protein that is known to bind directly to two sites in the carboxyl terminal region of dystrophin...

Lippia javanica leaves may have nutraceutical bioactivity and thus could be a viable alternative to antibiotic growth promoters in poultry diets. To test this hypothesis, a feeding trial was carried out to determine the effects of dietary inclusion of Lippia javanica leaf meal (LJ) on growth performance, blood parameters, carcass characteristics and meat quality of indigenous Potchefstroom Koekoek (PK) chickens. The leaf meal was used to dilute a commercial chicken grower diet at a rate of 25 or 50 g/kg diet...

Distinguishing treatable causes for rapidly progressive dementia from those that are incurable is vital. Creutzfeldt-Jakob disease (CJD) and voltage-gated potassium channel complex-associated autoimmune encephalitis (VGKC AE) are 2 such conditions with disparate outcomes and response to treatment. To determine the differences in electroencephalography between CJD and VGKC AE, we performed a retrospective review of medical records and examined clinical data, neuroimaging, and electroencephalographs performed in patients admitted for evaluation for rapidly progressive dementia diagnosed with CJD and VGKC AE at the Johns Hopkins Hospital and Bayview Medical Center between January 1, 2007 and December 31, 2015...

Background: Sodium-potassium adenosine triphosphatase (Na/K-ATPase) has been shown to regulate Src activity by combining with Src to keep it in an inactive form. We previously reported that Na/K-ATPase was downregulated in unilateral ureteral obstruction (UUO) animals. In this study, we examined whether inhibition of Na/K-ATPase-mediated Src signaling pathways ameliorated renal interstitial fibrosis induced by UUO. Methods: UUO was performed on male C57BL/6J mice...

Mutations leading to disorders within ion (mainly potassium and sodium) channels, have different degrees of expression in the brain and in the heart, which can cause simultaneous occurrence of disorders in both organs. This is manifested by the occurrence of epileptic seizures and cardiac electrical disturbances, further exacerbated by stimulation of autonomic structures within the central nervous system. In all patients with unclear paroxysmal disorders, and in those with unexplained sudden cardiac death, consideration should be given to the possibility of occurrence of genetically determined disorders in the ion channels...

Angiotensin-converting enzyme (ACE-I) inhibitors and ARBs have shown real efficacy in reducing blood pressure, proteinuria, in slowing the progression of chronic kidney disease (MRC) and in clinical improvement. in patients with heart failure, diabetes mellitus and ischemic heart disease. However, their use is limited by some side effects such as the increase in serum potassium (K), which can be particularly severe in patients with renal insufficiency. In the 23,000 patients followed by the PIRP project of the Emilia-Romagna Region, hyperkalaemia at the first visit (K> 5...

Bartter syndromes (BS) types 1-5 are rare salt-losing tubulopathies presenting with overlapping clinical phenotypes including marked salt wasting and hypokalemia leading to polyuria, polydipsia, volume contraction, muscle weakness and growth retardation. These diseases are due to an impairment of sodium, potassium, chloride reabsorption caused by mutations in genes encoding for ion channel or transporters expressed in specific nephron tubule segments. Particularly, BS type 3 is a clinically heterogeneous form caused by mutations in CLCNKB gene which encodes the ClC-Kb chloride channel involved in NaCl reabsorption in the renal tubule...

2-Methylisoborneol (2-MIB) is one of the most commonly observed taste and odor (T&O) compounds present in drinking water sources. As it is biodegradable, a preservation agent, typically mercury chloride, is needed if the water is not analyzed right after sampling. Since mercury is a toxic metal, an alternative chemical that is cheaper and less toxic is desirable. In this study, two chemicals commonly used in water treatment processes, chlorine (as sodium hypochlorite) and KMnO₄ (potassium permanganate), are studied to determine their feasibility as preservation agents for 2-MIB in water...

In this work, the action of heptanol and ethanol was investigated in a two-dimensional (2D) model of cardiac tissue: the neonatal rat ventricular myocyte monolayer. Heptanol is known in electrophysiology as a gap junction uncoupler but may also inhibit voltage-gated ionic channels. Ethanol is often associated with the occurrence of arrhythmias. These substances influence sodium, calcium, and potassium channels, but the complete mechanism of action of heptanol and ethanol remains unknown. The optical mapping method was used to measure conduction velocities (CVs) in concentrations of 0...

Aluminium dross, a waste generated from aluminium melting process, contains aluminium metal, aluminium oxide, aluminium oxy-nitride and impurities such as sodium chloride and potassium chloride. Since aluminium dross is land filled without treatment, it is hazardous to the environment. Conventional methods for the metal recovery from the recycling of aluminium dross involve chemicals and are time consuming. In this study, an attempt was made to treat aluminium dross using plasma arc melting process. The aluminium dross was melted and evaporated by the plasma arc established between a crucible anode and a rod type hollow cathode made of graphite...

A biophysical model that captures molecular homeostatic control of ions at the perisynaptic cradle (PsC) is of fundamental importance for understanding the interplay between astroglial and neuronal compartments. In this paper, we develop a multi-compartmental mathematical model which proposes a novel mechanism whereby the flow of cations in thin processes is restricted due to negatively charged membrane lipids which result in the formation of deep potential wells near the dipole heads. These wells restrict the flow of cations to "hopping" between adjacent wells as they transverse the process, and this surface retention of cations will be shown to give rise to the formation of potassium (K+) and sodium (Na+) microdomains at the PsC...
