A new high-performance liquid chromatography (HPLC) method for the sensitive simultaneous determination of hydrazine (Hy), monomethylhydrazine (MMH) and 1,1-dimethylhydrazine (UDMH) based upon the derivatization of hydrazines with naphthalene-2,3-dialdehyde and the separation of the derivatives on Zorbax Eclipse AAA column in a single chromatographic run under acidic conditions (pH 2.4) was developed. Hydrazine and monomethylhydrazine derivatives were found to be strongly fluorescent at λex = 273 nm, λem = 500 nm. It was shown that UDMH derivative can be detected as non-fluorescent hydrazone at 290 nm by UV-detection. Limits of detection were 0.05 μg · L-1 for Hy and MMH, and 1 μg · L-1 for UDMH for the injection volume of 100 μL. The method was validated for water sample analysis. It proved to be selective, accurate and precise with the supplementary advantage of the simple and rapid sample preparation. © 2013 Copyright Taylor and Francis Group, LLC.

A nanoparticulate (105 ± 10 nm) paclitaxel (97-98% entrapment) formulation based on lac-tic-glycolic acids copolymer was obtained via homogenization. Scanning electronic and atomic force microscopy were used for nanoparticles visualization. In vitro experiment results outline a potent cytotoxic effect of nanoparticulate paclitaxel formulation against human T-lymphoblastic leukemia cells, Jurkat WT. In vivo experiments revealed anticancer efficiency of nanoparticulate paclitaxel formulation against P-glycoprotein expressing mammary adenocarcinoma Ca755 in C57BL6 mice.

The research on the nansomal forms s of low-sialylated recombinant human erythropoietin (ls-rhEPO) gave evidence for the efficiency of the nanotechnological approach to targeted delivery of this protein to the brain of experimental animals. Nanosomal ls-rhEPO formulations were found to exhibit neuroprotector activity. The established ability of the nanosomal formulations of ls-rhEPO to enhance BDNF and NGF gene expression in animal brain is to a great extent responsible for the mechanism of the neuroprotector action of this protein. © 2013 Pleiades Publishing, Ltd.
