Improved nitrogen utilization in cattle is important in order to secure a sustainable cattle production. As purines and pyrimidines (PP) constitute an appreciable part of rumen nitrogen, an improved understanding of the absorption and intermediary metabolism of PP is essential. The present work describes the development and validation of a sensitive and specific method for simultaneous determination of 20 purines (adenine, guanine, guanosine, inosine, 2'-deoxyguanosine, 2'-deoxyinosine, xanthine, hypoxanthine), pyrimidines (cytosine, thymine, uracil, cytidine, uridine, thymidine, 2'-deoxyuridine), and their degradation products (uric acid, allantoin, β-alanine, β-ureidopropionic acid, β-aminoisobutyric acid) in blood plasma of dairy cows.

Using PCR analysis of pig-mink and pig-Chinese hamster hybrid cell lines and heterologous and homologous primers of various types, chromosomal and subchromosomal mapping of genes TOP2A, THRA, BRCA1, GAS, HLR1, MYL4, LIS1, MCP1, ENO3, CRYB1, P4HB, STAT5B, and H3F3B to pig chromosome 12 was carried out. The efficiency of using different types of heterologous primers for pig chromosome mapping was compared.

The chromosomal complements of somatic cell pig-mink hybrids was determined by a new approach. This approach includes microdissection of metaphase chromosomes, generation of chromosome and region-specific DNA libraries, and fluorescence in situ hybridization of these libraries with pig lymphocyte chromosomes. The studied hybrid cells were shown to contain two small acrocentric chromosomes and a microchromosome of porcine origin.
