Study of the Effects of Subsensory Influence on the System of Associations in Patients with Depressive Disorders

The article is devoted to the actual problem of studying the effects of unconscious perception and processing of subliminal visual verbal stimuli. Certain methodological problems arising in the research of transient perceptual-informational processes are defined. Significant differences in the course of such processes in healthy individuals and in patients with affective, primarily depressive disorders are emphasized. A description of the Technique of subsensory formating the associations, developed for researching the impact of subliminal visual verbal stimuli on psychosemantic structures of consciousness, is provided. The data on the examination of a sample of 69 people using the new technique are presented. The sample included 37 (53.62%) persons suffering from various forms of depressive disorders and 32 (46.38%) healthy persons of the control group. It is shown that an ultra-short exposure to the subsensory verbal stimuli with positive psychosemantic sense, demonstrated at the same time as the subject's attention is focused on the suprasensory target word, leads to a significant increase in positive associations with this word. It is noted that such effects are more pronounced in depressed patients than in healthy individuals. It is concluded that the obtained data open new prospects in the context of the development of modern personalized psychocorrective programs

The role of perceived source location in auditory stream segregation: separation affects sound organization, common fate does not

The human auditory system is capable of grouping sounds originating from different sound sources into coherent auditory streams, a process termed auditory stream segregation. Several cues can influence auditory stream segregation, but the full set of cues and the way in which they are integrated is still unknown. In the current study, we tested whether auditory motion can serve as a cue for segregating sequences of tones. Our hypothesis was that, following the principle of common fate, sounds emitted by sources moving together in space along similar trajectories will be more likely to be grouped into a single auditory stream, while sounds emitted by independently moving sources will more often be heard as two streams. Stimuli were derived from sound recordings in which the sound source motion was induced by walking humans. Although the results showed a clear effect of spatial separation, auditory motion had a negligible influence on stream segregation. Hence, auditory motion may not be used as a primitive cue in auditory stream segregation

Development of encapsulated extracts on the basis of meadowsweet (Filipendula ulmaria) in the composition of functional foods with oncoprotective properties

ArticleMeadowsweet (Filipendula ulmaria) is a quite common plant throughout the European countries, including Russia. Therapeutic and prophylactic properties of the meadowsweet are mainly associated with the action of biologically active substances (BAS), in particularly tannins, phenolic compounds, phenolcarboxylic acids, catechins, flavonoids, essential oils etc. The main substances with proven clinical effects are salicylates and flavonoids, what allows to consider meadowsweet as an anti-inflammatory, immunostimulating, antioxidant, hepatoprotective, nootropic, adaptogenic and antihypoxic agent. The aim of this study was to analyze the content of BAS in water and 70% ethyl alcohol extract of F. ulmaria flowers from different regions of Russia and develop their encapsulated forms for further use as an ingredient for functional food products. To increase the shelf life of meadowsweet extracts and create a stable form for their delivery to the human body with various food products, encapsulated forms of extracts in the form of microand nanosized capsules were developed. The method of encapsulation was carried out using a spray dryer. It was shown that encapsulated meadowsweet BAS can be added to a chicken pate without negative effect on the organoleptic properties of the finished product. The calculation of the cost of the meat product with the complex functional dry mixture showed a slight increase in the cost of the final product compared to the traditional analogue. This study shows that encapsulated meadowsweet BAS can be used for inclusion in various food products, to ensure the functional properties of food and optimize the population's rations

Do audio-visual motion cues promote segregation of auditory streams?

An audio-visual experiment using moving sound sources was designed to investigate whether the analysis of auditory scenes is modulated by synchronous presentation of visual information. Listeners were presented with an alternating sequence of two pure tones delivered by two separate sound sources. In different conditions, the two sound sources were either stationary or moving on random trajectories around the listener. Both the sounds and the movement trajectories were derived from recordings in which two humans were moving with loudspeakers attached to their heads. Visualized movement trajectories modeled by a computer animation were presented together with the sounds. In the main experiment, behavioral reports on sound organization were collected from young healthy volunteers. The proportion and stability of the different sound organizations were compared between the conditions in which the visualized trajectories matched the movement of the sound sources and when the two were independent of each other. The results corroborate earlier findings that separation of sound sources in space promotes segregation. However, no additional effect of auditory movement per se on the perceptual organization of sounds was obtained. Surprisingly, the presentation of movement-congruent visual cues did not strengthen the effects of spatial separation on segregating auditory streams. Our findings are consistent with the view that bistability in the auditory modality can occur independently from other modalities

STUDY OF PATHOGENETIC FEATURES INFECTIOUS CAUSED BY HIGHLY PATHOGENIC INFLUENZA VIRUS A/H5N1 IN WILD DUCKS AND DOMESTIC CHICKEN

Changes in lung, liver and brain were investigated, in wild, ducks and. domestic chicken under experimental infection caused by highly pathogenic avian Influenza virus A/H5N1. Isolation of virus was demonstrated, in swabs from the throat and. cloaca, virus titers were presented, in patterns of organs. Changes in organs of wild, ducks have dystrophic characteristics, but in domestic chickens are of the dystrophic and necrotic nature

Addition of Ag2O in Er3+doped oxyfluorophosphate glass to allow the drawing of optical fibers

Here, Ag2O containing glasses in the NaPO3–CaF2 glass network were prepared using standard melting process. The addition of Ag2O was found to increase the thermal stability of the glass due to the decrease in the Q2 units at the expense of Q1 units, to decrease the intensity of the upconversion under 980 nm pumping and to have a small impact on the nucleation and growth mechanism. Due to the thermal stability against crystallization of the glass prepared with 4 mol % of Ag2O, we demonstrate that fiber can be drawn from this glass. Despite the formation of Ag nanoparticles at the surface of the fiber although the drawing is a fast process, light can still be confined in the fiber. The fiber exhibits a large emission band centered at 1.5 μm under 980 nm pumping.Peer reviewe

Cellular imaging by green luminescence of Tb(III)-doped aminomodified silica nanoparticles

© 2017 Elsevier B.V.The work introduces Tb(III)-centered luminescence of amino-modified silica nanoparticles doped with Tb(III) complexes for cellular imaging. For these purposes water-in-oil procedure was optimized for synthesis of 20 and 35 nm luminescent nanoparticles with amino-groups embedded on the surface. The obtained results indicate an impact of the nanoparticle size in decoration, aggregation behavior and luminescent properties of the nanoparticles in protein-based buffer solutions. Formation of a protein-based corona on the nanoparticles surface was revealed through the effect of the nanoparticles on helical superstructure of BSA. This effect is evident from CD spectral data, while no any size impact on the adsorption of BSA onto aminomodified silica surface was observed. Cellular uptake of the nanoparticles studied by confocal and TEM microscopy methods indicates greater cellular uptake for the smaller nanoparticles. Cytotoxicity of the nanoparticles was found to agree well with their cellular uptake behavior, which in turn was found to be greater for the smaller nanoparticles

Particular attention is paid to the creation of new balanced in composition of products enriched with functional components, allowing them to increase their nutritional and biological value. Among vegetable crops, pumpkin is a highly valuable raw material in the food industry, which has equally both nutritional and biological value, and allowing for the correction of the human nutritional status. Based on this, we has been assessed the biochemical indicators of the varieties and hybrids of table pumpkin during to keeping as a perspectives raw material for the products of functional allocation in the Far East region. The research was carried out by the department of vegetable crops and potatoes of the Far Eastern Research Institute of Agriculture in the framework of the Far East program. Biochemical studies on pumpkin were carried out in the laboratory of agriculture of the Far Eastern Research Institute of Agriculture and in the laboratory of testing of the Center for Agrochemical Service “Khabarovsk” three times: 1 - before laying on to keeping; 2 - after 1.5 months of keeping; 3 - 1 month after the previous study. The results of studies showed that the varieties Nadezhda, Zimnyaya sladkay and Japanese hybrid Orange colon after 2.5 months of keeping, there was a decrease in some biochemical parameters. The varieties Vnuchka, Zhemchuzhina and a Japanese hybrid Sweet kob there is a tendency to increase almost all the quality indicators during the whole period of keeping. The content of dry matter, Vitamin C and potassium increases significantly. A favorable period for the processing of raw materials in the manufacture of the products of functional allocation is 1-2 months after harvesting for the Nadezhda variety and 1-4 months for the Vnuchka variety. Perspectives for the Far Eastern region in the manufacture of the products of functional allocation from foreign varieties are the Zimnyaya sladkay variety and the Japanese hybrid Orange colon.Производство продуктов функциональной направленности является одним из важнейших направлений развития пищевой промышленности.
