impurities of drug substances may produce some side effects in patient. diclofenac na is a member of non-steroidal anti inflammatory drugs (nsaids) family, which is routinely used by patients for the treatment of rheumatoid arthritis and various pains. to develop a method for the determination of synthetic precursors which could be remained as impurities in raw drug materials, na diclofenac pow...

There are considerable data to support the general hypothesis that accumulation of [Na]i during ischemia and early reperfusion leads, via Na/Ca exchange, to elevated [Ca]i, resulting in myocardial damage.1–10 Despite the strong support for the general aspects of this hypothesis, there is controversy regarding some details that have important implications for the design of therapeutic interventi...

a greenhouse research work was conducted to study the patterns of na+ and k+ distribution in root, stem and leaf during three growth stages of four iranian alfalfa ecotypes and to find correlation between these patterns and plant salt tolerance. treatments were replicated three times in a factorial experiment of a completely randomized block design. based on the threshold of salt tolerance in a...

GerN, a Bacillus cereus spore germination protein, exhibits homology to a widely distributed group of putative cation transporters or channel proteins. GerN complemented the Na(+)-sensitive phenotype of an Escherichia coli mutant that is deficient in Na(+)/H(+) antiport activity (strain KNabc). GerN also reduced the concentration of K(+) required to support growth of an E. coli mutant deficient...

Nicotianamine (NA) is a non-protein amino acid derivative synthesized from S-adenosyl L-methionine able to bind several metal ions such as iron, copper, manganese, zinc, or nickel. In plants, NA appears to be involved in iron availability and is essential for the plant to complete its biological cycle. In graminaceous plants, NA is also the precursor in the biosynthesis of phytosiderophores. Ar...
