[The health status of students studying information science at a physics and mathematics school].

The sanitary conditions of information technology classes, the capacities and health status of 10-11th form pupils thoroughly studying information technology were examined. Tests revealed that in the presence of poor conditions, such as reduced illumination, higher air temperatures, increased electromagnetic radiation, noncompliance of rest and work regimens, the pupils had poor working capacities and deteriorated subjective ill health and that adolescents with myopia, poor posture, and scoliosis increased in number.

[DNA genotyposcoy in determining paternity: use of hybridized probes].

Analysis of hybridization probes for DNA genotypescopy (DNA genotyping and genome fingerprinting) was performed to detect 21 cases of paternity testing. A system with the highly informative multilocus DNA probe Red4, isolated by us earlier, and two single-locus probes (YNH24 and CMM101) detecting highly polymorphic (H > 96%) loci D2S44 and D14S13 was tested. In the cases analyzed, the Red probe was shown to detect, on average, 19.

[Mapping the gene for palmoplantar hyperkeratosis (thylosis) to chromosome 17 in the 17q12-q24 region].

Mapping of the genetic defect causing dominant palmoplantaris hyperkeratosis (PPHK) was continued based on the material of an extended Uzbek pedigree. No linkage between the PPHK gene and hypervariable DNA markers from 8p, 12p, 14q, and 22q were revealed. The study of PPHK gene linkage with DNA markers covering the entire length of 17th chromosome mapped the PPHK gene to 17q12-q24 and revealed close linkage with KRT10 and D17S800 loci (zero recombination frequency at a lod score > 7).
