NCKX5 is an ion exchanger expressed mostly in pigment cells; however, the functional role for this protein in melanogenesis is not clear. A variant allele of SLC24A5, the gene encoding NCKX5, has been shown to correlate with lighter skin pigmentation in humans, indicating a key role for SLC24A5 in determining human skin colour. SLC24A5 expression has been found to be elevated in melanoma. Knock...

Among the conducting polymers, polyaniline (PANI) and polypyrrole (PPy) are the most popular. According to the Web of Science, more than 10,000 papers appeared in the past 30 years on various aspects of chemistry, physics, and engineering of PANI. This is due to the cheapness and easy availability of raw materials, ease of synthesis, good environmental stability, high electrical conductivity an...

These three component inorganic ion-exchanger was synthesized under different condition. The most thermal and chemical properties of this material is prepared by intermixing solutions of sodium molybdate (0.1 M), sodium arsenate (0.1 M) and antimony(III) chloride (0.1 M) solution in different volume ratios at pH-1. The Ion-exchange capacity of all the samples was determined by column process. T...

The kinetics of the esterification of n-butanol with acetic acid have been studied in a batch and in a tubular reactor. The best model for obtaining the esterification rate with a partially wet ion exchanger (270/o water contents) is obtained by assuming a pseudohomogeneous system, while the kinetics of dry ion exchangers is best represented by a model derived from assumptions based on a hetero...

The Na+/H+ exchanger is a pH-regulatory protein that extrudes one H+ ion in exchange for one Na+ ion when intracellular pH declines. A number of studies have shown phorbol ester stimulation of activity in intact cells, leading to the idea that the exchanger is regulated by protein kinase C-mediated phosphorylation in vivo. cDNA encoding the protein has been cloned, and a recent model suggests a...

Periodic mesoporous titanium phosphonate (PMTP-2) monoliths were synthesized by combining autoclaving process and evaporation-induced self-assembly strategy, which was functionalized by ClSO(3)H treatment, acting not only as an ion exchanger with large ion exchange capacity but also as a strong acid catalyst possible for some low-temperature reactions.
