[Modern surgical tactics in Crohn's disease].

Surgical tactics of Crohn's disease (CD) treatment was elaborated on base of modern information analysis, concerning pathogenesis, peculiarities of clinical course, possibilities of diagnosis, experience in the disease treatment. The tactics provides a timely diagnosis of the disease, prognostication for the recurrence occurrence and postoperative complications, the indications and the method of surgery optimization. Application of the elaborated surgical tactics in CD in 121 patients have permitted to improve the objective estimation of the disease severity, to prognosticate complications, to optimize surgical indications, as well as a choice of the method of a conditionally-radical, restorational, reconstructive-restorational stages of operative intervention, to reduce the disease recurrences rate, postoperative complications, postoperative lethality.

[Genetic diversity of modern Russian durum wheat cultivars at the gliadin-coding loci].

The allelic diversity at four gliadin-coding loci was examined in modern cultivars of the spring and winter durum wheat Triticum durum Desf. Comparative analysis of the allelic diversity showed that the gene pools of these two types of durum wheat, having different life styles, were considerably different. For the modern spring durum wheat cultivars, a certain reduction of the genetic diversity was observed compared to the cultivars bred in the 20th century.

Braunomyces dictyosporus gen. sp. nov. from Vietnam.

The generic name Braunomyces (ascomycetes, asexual morph), with B. dictyosporus as type species, is described, illustrated and discussed, based on material collected in Vietnam on leaf debris of an unidentified broadleaved tree. The new genus is well characterised and quite distinct from other synnematous and non-synnematous dematiaceous hyphomycete genera by its unique combination of traits, viz.

[Methods for the surgical treatment of chronic sphenoiditis and ethmoiditis].

The objective of the present study was to design tools for the enhancement of safety of the surgical instruments used in the treatment of chronic sphenoiditis and ethmoiditis. The proposed instruments for endonasal surgery on sphenoidal sinuses and posterior cells of the ethmoidal labyrinth make it possible to improve the quality of surgical interventions, decrease their duration , and reduce the risk of damage to the important anatomical structures. The instruments were used for the surgical treatment of 120 patients that produced no complications.

[Giant protists (xenophyophores and komokiaceans) from the Clarion-Clipperton ferromanganese nodule field (Eastern Pacific)].

Our previous investigations showed that giant protists (xenophyophores and komokiaceans) are one of the key groups in the deep-sea mega- and macrobenthos, dominating in density and biomass in some areas of the World Ocean. Analyses of 38600 seafloor photographs and fauna from 30 box-corers taken in the Russian Exploratory area at the Clarion-Clipperton Fracture Zone ferromanganese nodule field revealed a diverse and abundant fauna of these organisms. Xenophyophores were found on 70% of seafloor photographs.
