Modified cold-induced aggregation microextraction (M-CIAME) is a fast and simple method for extraction and preconcentration of metal ions from samples with high salt content. Furthermore, this technique is much safer in comparison with the organic solvent extraction. The extraction of palladium (Pd) was performed in the presence of Michler thioketone (TMK) as the complexing agent. In this metho...

We show that cell lines derived from childhood alveolar rhabdomyosarcoma (RMS) are very sensitive to the growth-inhibitory effects of the immunosuppressive agent rapamycin (RAP), compared to other human cell lines (50% inhibitory concentration range of 0.1-8 ng/mi, compared to 1280 to >10,000 ng/ml). Our data suggest that the sensitivity of RMS lines is due to RAP inhibition of insulin-like gro...

Ternary semiconductor CdZnS films were prepared by chemical bath deposition (CBD). Effect of Zn concentration and deposition time on the forming chaarcterization of CdZnS films are investigated by the optical transmission spectra. The competition mechanism of Zn and Cd with the complexing agent NH3 to forming the complex play a critical role in the forming of Cd1-xZnxS thin film when Zn concent...

agent technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations due to its capability to automatically modify themselves in response to changes in their operating environment. multi agent system (mas) approach is the construction of a complex system as a se...

Metal conductive ink for flexible electroncs has exhibited a promising future recently. Here, an innovative strategy was reported to synthesize silver nanocolloid (2.5±0.5 nm) and separate solid silver nanoparticles (<10 nm) effectively. Specifically, silver nitrate (AgNO3) was used as a silver precursor, sodium borohydride (NaBH4) as a reducing agent, fatty acid (CnH2n+1COOH) as a dispersant a...

A method for the automated determination of aluminum in a variety of beverages is described. The method utilizes lumogallion as a complexing agent in a buffer solution. The system is very similar to flow-injection analysis (FIA), however, the tubing id is larger than that typically used in FIA. Therefore, the system is best described as non-segmented continuous flow analysis using fluorescence ...

Tetrathiomolybdate (TM) is a potent nontoxic orally delivered copper complexing agent under development for the last several years for the treatment of Wilson's disease. It has been shown to block angiogenesis in primary and metastatic tumors. Therefore, the combination of cytotoxic radiotherapy (RT) and antiangiogenic TM could target both the existing tumor and the tumor microvasculature in a ...

Though the past few decades, the development of new luminescent materials has received a lot of attention due to their applications as fluorescent sensors, in biological microscopy and in optoelectronic devices. Most of these applications are relied on intramolecular charge transfer (ICT). Presence of electron withdrawing N-heterocycles such as pyrazine and quinoxaline rings appeared therefore ...

In this paper, we demonstrate a new promising resonance Raman (RR)-based method for the determination of Fe3+ concentrations in aqueous solutions. Iron ions were quantified at a low concentration range by employing hydroxylamine hydrochloride as the reductant, and phenanthroline as the complexing agent, thereby reducing Fe3+ to Fe2+. The addition of Fe3+ to the detection reagent resulted in a r...
