The purpose of this study was to investigate volume regulation in the lens and its involvement in lens opacification (cataract) and the role of chloride channels in these processes. Single, isolated lens fiber cells from the lens were whole cell patch clamped. When exposed to hypotonic solution, and outwardly rectifying whole-cell current was activated. The current increased from 1.0 to 32.6 pA...

The changes in the membrane permeability to sodium, potassium, and chloride ions as well as the changes in the intracellular concentration of these ions were studied on frog sartorius muscles in Ca-free EDTA solution. It was found that the rate constants for potassium and chloride efflux became almost constant within 10 minutes in the absence of external calcium ions, that for potassium increas...

We compared two methods for separation of serum high-density lipoprotein: selective precipitation with sodium phosphotungstate and magnesium chloride, and ultracentrifugation in sodium chloride solution (relative density 1.063). When the cholesterol content (determined enzymically with a centrifugal analyzer) of fractions obtained by each method was compared (ultracentrifugation = x), the corre...

The effects of a chloride-poor medium (methanesulfonate substituted) and a chloride transport inhibitor (SITS) on the outward delayed current and the tonic tension were studied on frog atrial trabeculae under voltage-clamp conditions. The outward delayed current decreased in low-chloride medium (10.5 mmol/l) or in the presence of SITS (2 mmol/l). The tonic tension increased in chloride-poor sol...

A research on the corrosion inhibition of mild steel pitting corrosion in concrete pore solution by sodium nitrite was carried out by employing potentiodynamic, potentiostatic polarization and zero resistance ammetery (ZRA) techniques. Passivity breakdown potential was decreased from the transpassive potential of 700 mV at the absence of chloride to a value of -50 mV when just 0.01M NaCl was ad...

1. It is well known that neutral salts depress the osmotic pressure, swelling, and viscosity of protein-acid salts. Measurements of the P.D. between gelatin chloride solutions contained in a collodion bag and an outside aqueous solution show that the salt depresses the P.D. in the same proportion as it depresses the osmotic pressure of the gelatin chloride solution. 2. Measurements of the hydro...

In this paper, the influence of fly ash content on concrete surface chloride concentration was investigated through periodical tests of surface chloride concentration of concrete by immersing three kinds of concrete specimens in 5.0 wt.% sodium chloride solution. One kind of specimen is common concrete without fly ash, whereas the other two kinds of specimens are mixed with fly ash. The results...

The idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. In addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. A useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

in this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic ionic liquids (ils), 1 – allyl - 3 - methylimidazolium chloride ([amim]cl), 1 - ethyl - 3 - methylimidazolium chloride ([emim]cl), 1 - butyl - 3 - methylimidazolium chloride ([bmim]cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([bmim]bf4) were investigated using conductivity and laser light scatterin...
