[Apparatus for external fixation of the hand].

The authors offered the apparatus for external fixation of the hand. A medical plastic is used for making the support of an improvised apparatus. The pins "sealed" in plastic and fixed bone fragments.

[An oligonucleotide microarray for detection and discrimination of orthopoxviruses based on oligonucleotide sequences of two viral genes].

An oligonucleotide microarray for detection and identification of orthopoxviruses was developed. Genus specific and orthopoxvirus species-specific regions of the genes encoding chemokine binding and alpha/beta-interferon binding proteins were used as a target. The developed microarray allows the variola, monkeypox, cowpox, vaccinia, camel-pox and ectromelia (mousepox) viruses to be distinguished with a high degree of reliability.

[Liquid phase method of synthesizing polyamides binding DNA using oligocarboxamide blocks].

A method was developed for the synthesis of sequence-specific polyamides on the basis of 4-amino-1-methylpyrrole-2-carboxylic acid, 4-amino-1-methylimidazole-2-carboxylic acid, beta-alanine, and gamma-aminobutyric acid. Dimeric and trimeric oligocarboxamides were used as building blocks. Our synthetic scheme was applied for the synthesis of DNA minor groove binders containing up to twelve carboxamide units.

[Phylogenetic analysis of chemokine-binding protein gene from orthopoxviruses].

Poxviruses, belonging to the genus of Orthopoxviruses and Leporipoxviruses, express a protein that binds a wide spectrum of CC-chenokines. The above viral protein (vCCI) has no homology by the amino acid sequence with the known cellular receptors of chemokines or with any other proteins represented in databases. Sixty-nine nucleotide sequences of the vCCI protein gene of 4 Orthopoxviruses, which are pathogenic to man, and of 2 species, to whom man is immune, as well as 16 of such sequences borrowed from GenBank were subjected to the phylogenetic analysis.

[A rapid and effective solid-phase synthesis of DNA-sequence binding polyamides].

A rapid and effective variant of solid-phase synthesis of DNA-sequence-specific polyamides on the basis of 4-amino-1-methylpyrrole-2-carboxylic acid, 4-amino-1-methylimidazole-2-carboxylic acid, beta-alanine, and gamma-aminobutyric acid was suggested. It is based on the use of di- and trimeric oligocarboxamide building blocks, which help reduce the time of synthesis, increase its yield and purity of products, and efficiently use manual synthesis for the synthesis of long oligocarboxamides. The yields of hairpin ligands with up to 10 units are 35-50% and the synthesis takes no more than 6 h.
