Hydrangea macrophylla is popular for its unique physiological characteristics and changeable colors. Previous studies have shown that the pH of vacuoles sepal cells hydrangea affects color sepals. Located on vacuolar membrane, NHX1 an important H+ proton pump drives exchange metal ions. This environment by controlling accumulation in vacuole. In hydrangea, HmNHX1 gene has open reading frame 162...

Disposable devices for sensing biomarkers like Na+ ion in sweat was developed using UV-Ozone irradiated laser-induced graphene (LIG) based electrodes. Solid-state ion-selective electrodes (ISEs) sensitive to ions were fabricated by a two-step drop-coating process of polyvinyl chloride solution containing plasticizer, ionophore and ion-exchanger on LIG electrode. Hydrophobic hydrophilic transiti...

Previously, we reported that renal active calcium-transporting genes are highly expressed in female mice and suggested that renal calcium-processing genes play a critical role in normal calcium reabsorption in females (Lee GS, Lee KY, Choi KC, Ryu YH, Paik SG, Oh GT, Jeung EB. J Bone Miner Res 22: 1968-1978, 2007). In the current study, we evaluated the differential expression of renal calcium-...

The conventicnal sulfate determination by gravimetrically precipitating barium sulfate is very tedious and time consuming. The present technique uses an ion exchanger so the sulfate can be titrimetrically determined as sulfuric acid. An analysis can be completed in 30 minutes. This method is being used for the routine analysis of sulfate in mixtures of gypsum, anhydrite, calcium oxide, and calc...

The sodium-hydrogen exchanger isoform-1 [NHE1] is a ubiquitously expressed plasma membrane protein that plays a central role in intracellular pH and cell volume homeostasis by catalyzing an electroneutral exchange of extracellular sodium and intracellular hydrogen. Outside of this important physiological function, the NHE1 cytosolic tail domain acts as a molecular scaffold regulating cell survi...

This paper describes a lithography-based microfabrication process developed for a recuperative heat exchanger intended for use in a cryosurgical probe. The probe, which uses the Joule-Thomson (JT) cooling cycle, must achieve a temperature < -50°C, with a freeze rate of 25-50°C/min. The heat exchanger must maintain high stream-to-stream thermal conductance while restricting parasitic stream-wise...

A study of the transient potential signals obtained with a cation-selective electrode based on an ion-exchanger was carried out for solutions following individual cations at different concentrations: H+, Li+, Na+, K+, Rb+, Mg2+, Ca2+, choline (Ch+), acetylcholine (AcCh+), and procaine (Pr+). Three general types were distinguished depending value selectivity coefficient corresponding ion. princi...

Iron(III) was loaded onto the sulphonic acid sites of Duolite C26, a commercial cation-exchanger, and was then converted into hydrated ferric oxides (HFO) disbursed throughout the macropores of the ion exchanger beads. The resulting hydrated iron(III)-oxide loaded cation exchange resin (HFOLR) was tested for its ability to remove arsenate [As(V)] ions present in water by batch technology. The s...

Purified elastin was hydrolysed with HCl and manipulated under conditions that minimized oxidation. Gel-permeation chromatography on polyacrylamide gel and ion-exchange chromatography on dextran cation-exchanger each resulted in the separation of a series of yellow fluorescent fractions. These hitherto unreported ampholytes have fluorescence spectra that approximate to that of the intact protei...

A p-nitrophenolate-sensitive membrane electrode was constructed by using tetraheptylammonium chloride as an ion-exchanger and o-nitrophenyl phenyl ether as a membrane solvent. The electrode responded to p-nitrophenolate down to 1 ,ƒÊM in a buffer solution of 0.1 M Na2CO3NaHCO3 (pH 10). The selectivity coefficients of the electrode to typical anions increased in the following order: Cl-<NO3< SCN...
