[Diagnosis and treatment strategy of malignant pleural effusions in outpatient conditions].

According to results of the study, which included 52 patients with malignant pleural effusion of unknown etiology, it could be concluded that the method of choice in differential diagnosis of pleural effusion is the immunocytochemistry as the most informative method (efficacy 94,2%). Based on own experience of treatment of 137 patients with recurrent malignant pleural effusions, we can say that the first stage of treatment of pleural effusions is carrying out pleurodesis in outpatient conditions. The choice of pleurodesis method, first of all, depends on the aggressiveness of tumor pleurisy: in a case of daily exudation till 300 ml we choose talc pleurodesis, from 300 to 700--bleomycin pleurodesis, more than 700--combined (talc and bleomycin pleurodesis). The overall efficiency of produced pleurodesis is 64.5%.

[2D digitizing of plant cell areolation by polarized light microscopy].

An algoriphm for plant parenchimal cell delineation is developed. It works with digital photos made by polarized light microscope and allows digitize many parameter of each cell thus providing a lot of data characterizing plant tissue. Examples are given for unisratose lamina of leaves of two closely related moss species. Plagiomnium elatum and P. medium. We demonstrate a comparison of dimensional patterns in leaves and ability of formalization of such a structural character as arrangement of cells in oblique rows.

Origin of coupling to antisymmetric modes in arc-induced long-period fiber gratings.

We study the origin of antisymmetric perturbation of the fiber in arc-induced long-period gratings that couple the core mode into the antisymmetric cladding modes. We demonstrate that this perturbation is caused by the temperature gradient in the fiber, which is induced, in turn, by the temperature gradient in the arc discharge. The reproducibility of the process of the grating inscription is higher when the fiber is placed in a region with larger temperature gradient.

[The characteristics of the circadian motor activity of sturgeons and their hybrids studied by a motion picture-TV method]. / Izuchenie osobennostei sutochnoi dvigatel'noi aktivnosti osetrovykh ryb i ikh gibridov kinotelevizionnym metodom.

Technique of slow-motion shot was used for simultaneous automatic recording of behaviour of sturgeon species Acipenser nudiventris and its hybrid with white sturgeon, Huso huso. The hybrids and the individuals of the paternal species were placed in two separate aquaria under the conditions of constant light. Cinematographic recording was performed each hour throughout 3 days during 30 s per hour. Significant differences between two kinds of sturgeons were found in the locomotor activity, trajectory of swimming, the average value and circadian rhythm of the swimming speed. The hybrid individuals swim faster and display a high peak of night activity. This puts them close to the maternal species, white sturgeon, and gives evidence of the maternal inheritance of these traits.
