Aminoazole-Based Diversity-Oriented Synthesis of Heterocycles.

The comprehensive review contains the analysis of literature data concerning reactions of heterocyclization of aminoazoles and demonstrates the application of these types of transformations in diversity-oriented synthesis. The review is oriented to wide range of chemists working in the field of organic synthesis and both experimental and theoretical studies of nitrogen-containing heterocycles.

[The oligoclonal expansion of T cells: study of its stability over time].

A novel experimental approach to the investigation of the repertoire of peripheral T lymphocytes of patients suffering from ankylosing spondylitis (AS) is proposed. This approach is based on the wide-range sequencing of cDNA of the beta-chain of the T-cellular receptor (TcR). The results of the analysis of the diversity of sequences of the TcR antigen-binding domain (CDR3) inside the total pool of one patient with AS are presented by the example of the second V family (BV2) of TcR.
