Localization of Calliphora erythrocephala chromosome 6 in a 3D nuclear space at different stages of nurse cell chromatin polytenization was analyzed by fluorescence in situ hybridization and 3D microscopy. The obtained results suggest a large-scale chromatin relocation in the C. erythrocephala nurse cell nuclei, which is accompanied by a change in the(More)
In the germarium of polytrophic ovarioles of Calliphora erythrocephala (Mg.) fly, four mitotic divisions of cystoblasts give rise to 16-cell germ-line cysts. One cell differentiates into an oocyte, while the remaining 15 cells become nurse cells. Concomitantly actin-rich ring canals are formed at the intercellular junctions. The present study considers a(More)
The genome assembly of southern house mosquito Cx. quinquefasciatus is represented by a high number of supercontigs with no order or orientation on the chromosomes. Although cytogenetic maps for the polytene chromosomes of this mosquito have been developed, their utilization for the genome mapping remains difficult because of the low number of high-quality(More)
Intranuclear dynamics of chromosome 6 in nurse cell nuclei of Calliphora erythrocephala Mg. (Diptera: Calliphoridae) was studied. The 3D FISH method was used for the first time to study chromosome territories in highly polyploid nuclei whose chromosomes undergo morphological changes. A considerable change in the intranuclear location of chromosome 6 and a(More)
Multicolor 3D fluorescence in situ hybridization was used to study arrangement of rRNA genes in Calliphora erythrocephala nurse cell nuclei with different levels of polyteny. It has been shown that the rRNA genes are exclusively localized to chromosome 6, suggesting that chromosome 6 is the only C. erythrocephala chromosome responsible for nucleolar(More)

We undertook a balneological survey of the Belokurikha spa and health resort territory with the purpose of distinguishing and identifying the potential health-improvement areas most promising for the extension and optimization of the therapeutic, tourist and recreational activities. The assessment was focused on the characteristic of the landscape and(More)
