[Spacial structure of epiphytic yeast communities on fruits of Sorbus aucuparia L].

The subject of this research is epiphytic yeast communities that form on the surface of Sorbus aucuparia. The object is to make quantitative assessment of the yeast communities' differentiation of the same but distant substratum. Results of the factor variance nidicolous analysis demonstrated that with increase in distances, there are increases in the variation of total number and relative abundance of the dominant yeast communities.

[Characterization of yeast groupings in the phyllosphere of Sphagnum mosses].

Significant differences were revealed in the taxonomic structure of the epiphytic yeast communities formed on Sphagnum mosses and on the leaves of vascular plants. On mosses, low abundance of red yeasts was found (the most typical epiphytes on vascular plant leaves), along with a relatively high content and diversity of nonpigmented dimorphic basidiomycetes related to the order Leucosporidiales. The species composition of epiphytic yeasts from mosses is different from that of both forest and meadow grasses and of the parts of vascular plants submerged in the turf.

[Influence of Lumbricus terrestris earthworms on the structure of the yeast community of forest litter].

The taxonomic structure of yeast communities was studied in forest litter and soil, as well as in substrates transformed by the activity of Lumbricus terrestris earthworms (tree waste from the hole mouths, the gut contents, and coproliths). The activity of L. terrestris has a weak effect on the total yeast abundance but results in substantial changes in their taxonomic composition.

[Pigmented basidiomycete yeasts are a promising source of carotenoids and ubiquinone Q10].

Strains of basidiomycete yeasts isolated from different sources were studied in order to determine the content of carotenoid pigments and ubiquinone Q10 for subsequent selection work to obtain producers of these substances. High specific productivity of carotenoids (600-700 mg/g) was revealed in the representatives of the following species: Cystofilobasidium capitatum. Rhodosporidium diobovatum, R.

[Massive isolation of anamorphous ascomycete yeasts Candida oleophila from plant phyllosphere].

Many years of research has confirmed a wide distribution of anamorphous ascomycete yeasts in the phyllosphere of diverse plants of the Moscow oblast. Based on the standard morphological and physiological criteria, on the results of restriction analysis of the 5.8S-ITS rDNA region, and on the sequencing of the D1D2 region of 26S rDNA, these yeasts were identified as Candida oleophila Montrocher.

[Geographical races of certain species of ascomycetous yeasts in the Moscow and Novosibirsk regions].

Strains of three species of the ascomycetous yeasts Hanseniaspora guilliermondii, Torulaspora delbrueckii, and Debaryomyces hansenii, isolated from the above-ground parts of plants in similar biocenoses of distant geographic regions (Moscow and Novosibirsk regions), have been investigated. The strains in each species were indistinguishable with respect to phenotypic features and general DNA characteristics as determined by restriction analysis. However, comparison of the strains using PCR analysis with nonspecific primers revealed considerable intraspecific variability.

[First isolation of the yeast Saccharomyces paradoxus in Western Siberia].

Two ascomycetous yeast strains have been isolated near Novosibirsk from oak exudate. The strains have been identified as Saccharomyces paradoxus Bachinskaya based on the results of biochemical tests. The conspecificity of the isolates with S.

[Effects of the autonomic nervous system function on the course of postoperative period in surgical removal of vocal cords polyps with Nd:YAG-laser].

The study of the effects of autonomic nervous system (ANS) function on the course of the postoperative period after removal of the vocal cord polyps with Nd:YAG laser has shown that laryngeal operations with utilization of Nd:YAG laser accelerate normalization of structural-functional condition of the vocal cords in patients with adequate autonomic support by 25-40 days compared to those with inadequate ANS function.

[Characteristics of adrenergic innervation of the somatic muscles].

The aim of the present study was luminescent-histochemical study of efferent adrenergic nervous apparatus of cross-striated somatic muscles. The adrenergic innervation of human laryngeal muscles--m. thyroarytenoideus internus (m.

[Functional status of the autonomic nervous system in patients with polyps of the vocal cords].

Assessment of functional state of the autonomic nervous system (tonicity, reactivity, support of the cardiovascular system) was made in 34 patients aged 18-64 years admitted to the ENT Research Institute for removal of laryngeal tumors. All the patients were diagnosed to have polyps of the vocal folds. Comprehensive studies suggest the conclusion on morphofunctional changes in the vocal folds which combine with adaptation-trophic disorders in the autonomic nervous system.
