[Confocal laser endomicroscopy in the diagnosis of diseases of biliary ducts].

Are clinical observations of various diseases of the bile ducts, including cholangiocarcinoma, developed with chronic diseases pancreato-biliary zone. Reflected the complexity of instrumental diagnostics at an early stage of the disease. For the first time at the given pathology diagnostic purposes was applied the method of probe confocal laser endomicroscopy allowed in all cases to clarify and verify the diagnosis.

[E.V. Anan'ev's contribution to studies of the centromere and construction of an artificial plant chromosome].

The plant centromere has been described to consist of blocks of repetitive DNA sequences, and self-assembly of an artificial plant chromosome has been achieved using individual cloned elements. E.V.

[Hoppel-family of mobile elements of Drosophila melanogaster, flanked by short inverted repeats and having preferential localization in the heterochromatin regions of the genome].

A mobile element (ME) having 91% homology with Dm1360 (Kholodilov et al., 1987) has been cloned from the Drosophila melanogaster genome and sequenced. The family of ME was designated hoppel.

[Amplification of subtelomeric sequences in "long" telomers of Drosophila melanogaster polytene chromosomes].

Drosophila melanogaster heat-resistant stock T32 is characterized by additional chromatin in the telomeres of the X and 2L chromosomes. Moreover, elevated (32 degrees C) temperature provokes high instability in the telomere morphology, so that sublines can be obtained which have additional chromatin in different chromosomes. Morphological patterns of telomeres in each subline are stable, if flies are kept at 23 degrees C.
