Current models of mitotic chromosome structure are based largely on the examination of maximally condensed metaphase chromosomes. Here, we test these models by correlating the distribution of two scaffold components with the appearance of prophase chromosome folding intermediates. We confirm an axial distribution of topoisomerase IIalpha and the condensin(More)

The influence of remediation of oil-contaminated gray forest, dark gray forest, and black soils by biological preparations Bacispecin, Devoroil, and Belvitamil on the population of opportunistic and phytotoxic fungi was studied. It was found that this population increased after oil pollution and decreased after three months of remediation. The latter is a(More)
Preparations of prodigiosin inhibited the activity of nuclese of Serratia marcescens. The preparations were fractionated on an alumina column. The activity of nuclease was inhibited by both fractions containing pyrryldipyrrylmethene compounds and fractions in which these compounds were not found by spectrophotometry. The inhibitor was isolated also from the(More)
Garden angelica (Archangelica officinalis L.) tolerance to the action of Urals crude oil was studied. It was established that, at the oil dose up to 30 g/kg of soil, plant weight was increased and the photosynthetic apparatus was activated. Garden angelica manifested tolerance to oil dose up to 60 g/kg. It is proposed to use this plant for remediation of(More)
Erytyrocyte volume in neonates is 25.8% greater than in women. Electrophoretic erythrocyte mobility was the same in neonates and in parturient women. The results obtained indicate that the more heterogeneous the hemoglobin system, the more heterogenous are erythrocyte membrane electrical characteristics.
The impact of pollution of different types of soils (leached chernozem, grey wood and dark-grey wood soils) with petroleum and its products on the size, species-specific composition, and accumulation of opportunistic micromycetes was studied in long-term field microallotment and laboratory conditions. Petroleum and its refining products were shown to(More)
The accidental discharge of oil or petroleum products in the course of their production, processing, or transportation results in the long-term pollution of natural landscapes. Entering the soil, these pollutants alter its physicochemical properties, reduce its fecundity, and largely suppress the biota (Kireeva et al. , 2001). Therefore, biological methods(More)
