[Relationship between the female fertility function of the ecs locus and the gene for a minor chorion s70 protein of Drosophila melanogaster].

The staket strain carrying an electrophoretic variant of the minor chorion protein was used to determine the chromosomal location of the s70 gene. The gene was shown to locate within the Df(1)sta (1E1-2-2B3-4) and outside the Df(1)At127 (1E1-2-2A1-2). Therefore, the s70 chorion gene resides within the region 2A1-2-2B3-4 on the X-chromosome, i.

[The regulation of the ontogenetic expression of the heat-shock genes from puff 67B in the salivary glands of Drosophila melanogaster].

The 67B locus contains a cluster of heat-shock genes, four of which (hsp22, hsp23, hsp26, hsp28) are ecdysterone-inducible. Experiments on the transcription of these genes in salivary glands of pupating larvae showed that hsp23 and hsp28 mRNAs were most abundant in the larvae while hsp26 and hsp22 had intermediate or low level of accumulation, respectively. The second series of experiments have demonstrated that mutations of ecs gene or its deletion reduce either the transcription rate or stability of small hsp mRNAs.

[Molecular-genetic analysis of of the band 10A1-2 in the Drosophila melanogaster chromosome X].

With the help of in situ hybridization respective location of 33 microclones from the genomic library of the Drosophila melanogaster large band 10A1-2, 4 clones obtained by chromosomal walking and 18 chromosomal rearrangements with breakpoints in the limits of this band was determined. A DNA fragment homologous to poly(A)+ RNA from the 3rd instar larvae has been revealed. Summarizing the obtained and published data, at least 3 genes and 6 transcriptionally active fragments appear to be located in the 10A1-2 band.

[Principle of organizational and technical unity in designing complex hardware for the processes in polyclinic care].

A method to describe processes of health care in outpatient clinics is proposed. It produces necessary conditions for interactions between designers and users of medical complex hardware at the stage of the development.
