Metformin in its protonated form as metformin hydrochloride is used worldwide an advanced antidiabetic drug for type 2 diabetes. Hyperinsulinemia and insulin resistance of cells are the main causes this disease. For patients with diabetes, (MET) works by improving cell sensitivity to insulin.
 It has been shown that methyl orange (MO) forms ionic associate can be isolated solid suitable cr...

A highly selective PVC membrane electrode based on a cerium-salen complex was prepared. The sensor displays an anti-Hofmeister selectivity sequence with a preference for iodide ion over many common organic and inorganic anions. The proposed electrode exhibits a near-Nernstian behavior over a wide concentration range (5.0 x 10(-2) - 8.0 x 10(-6) M) with a slope of 57.5 mV per decade, and a detec...

Coated wire lithium ion selective electrode was fabricated using lithium ionophore-VI, 2-nitrophenyl octyl ether (NPOE) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) on platinum wire. Lithium ion selective electrode was giving Nernstian response from 10 -1 M to 10 -4 M with a detection limit of 3x10 -5 M. The calibration slope of this lithium ion selective electrode was found to be 58....

The development of ion-selective electrodes (ISEs) for electrolyte measurements necessitates a re-evaluation of the biological and clinical interpretation of a result. In pathological situations (e.g., hyperlipidemia and hyperproteinemia) direct potentiometry is the method of choice for ion measurements in blood. However, the "plasma water effect" exists also in normal samples, requiring new re...

in this research, the interaction of hexadecyl trimahyl ammonium bromide (htab) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. the obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as wyman binding pote...

objective: evidence shows that the powder/liquid mixing ratio recommended by the manufacturers is often not respected when mixing the glass ionomer (gi) powder and liquid, yielding a gi cement with disproportionate powder/liquid ratio. considering the confirmed effect of powder/liquid ratio on the gi properties, and more importantly, its fluoride release potential, this study aimed to assess th...
