Albumin Retains Its Transport Function after Interaction with Cerium Dioxide Nanoparticles.

The interaction of inorganic nanomaterials with biological fluids containing proteins can lead not only to the formation of a protein corona and thereby to a change in the biological activity of nanoparticles but also to a significant effect on the structural and functional properties of the biomolecules themselves. This work studied the interaction of nanoscale CeO, the most versatile nanozyme, with human serum albumin (HSA). Fourier transform infrared spectroscopy, MALDI-TOF mass spectrometry, UV-vis spectroscopy, and fluorescence spectroscopy confirmed the formation of HSA-CeO nanoparticle conjugates.

Photosensitizer Radachlorin®: Skin cancer PDT phase II clinical trials.

"Radachlorin"(®), also known in the EU as Bremachlorin, a composition of 3 chlorophyll a derivatives in an aqueous solution, was introduced into the Russian Pharmacopoeia. Its GMP (Good Manufacturing Practice) facility based manufacturing method was patented. Laboratory experiments and clinical phase I were performed.

[Syringa species: molecular marking of species and cultivars].

RAPD analysis was carried out with 22 accessions of the genus Syringa, including six species, one interspecific hybrid, and 15 cultivars. In total, 500 polymorphic fragments were detected; species-specific and cultivar-specific markers were identified. For the first time, genetic polymorphism and genome similarity coefficients were estimated and phylogenetic relationships were established for the genus Syringa.

[Change in the spectra of peroxidases in regenerants of Stachys sieboldii (Miq.) as a result of hormonal and mutagenic effects].

Nodular segments of the stem and stolons of aseptic Stachys sieboldii (Miq.) plants were cultured in Gamborg's B5 medium at a low (1-2 mg/l) or high (10 mg/l) concentration of cytokinins (6-BAP, kinetin) and produced many adventitious buds and shoots without callus formation. Several plants were regenerated from nodular segments incubated at various concentrations of 5-bromodeoxiuridine (5-BdU) for three weeks.
