In our work we aimed to conduct a fundamental study of the process of morphological disorganization of the structural components of the mucous membrane and cartilage of the larynx at the end of the seventh day of experimental opioid effects at the microstructural level. This information in the future will allow to form a pathomorphological base, which will be used to compare the components of the mucous membrane and cartilage of the larynx in the norm with the dynamics of their changes as a result of experimental opioid effects at different times.

In our work we aimed to study the pathomorphological manifestations among the structural components of the laryngeal mucosa and cartilage in the later stages of the experimental opioid effect. This goal was achieved through the use of histological techniques to visualize the structural components of the laryngeal mucosa and cartilage. Histological sections with a thickness of 5 -7 mm were made. Histological specimens were prepared according to conventional methods using the dye hematoxylin, eosin, azan according to the method of Heidenhain, PAS-reaction according to Mc-Manus and Alcian blue according to Steedman. Microscopic examinations and photographing of the preparations were performed using an MBI-1 microscope and a Nicon D 3100 digital camera.At the end of 42 days of experimental exposure, the epithelial layer of the epiglottis was inhomogeneously thickened, with excessive accumulation on its pharyngeal and apical part of the stratum corneum. Individual epitheliocytes of the pharyngeal part of the epiglottis underwent necrotic changes, the horny substance loosened in places. On the pharyngeal surface of the mucous membrane found a small amount of mucus with impurities of erythrocytes. Dyscirculatory processes were also registered in the animals of the experimental group. In particular, dilatation and overflow of erythrocytes of vessels of own plate of a mucous membrane of an epiglottis, and also polymorphonuclear infiltration of own plate of a mucous membrane were observed.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.

Environmental contextAs atmospheric CO2 levels rise due to human activities, more of the gas dissolves in the oceans, increasing their acidity. The effect of these seawater changes on marine organisms is largely unknown. We examine the consequences of higher CO2 levels on the production by plankton of dimethyl sulfide, a climatically active gas. We find that higher CO2 levels leads to lower concentrations of dimethyl sulfide in the seawater, which has potentially important implications for the future climate. AbstractThe oceans have absorbed approximately half of the CO2 produced by human activities and it is inevitable that surface seawaters will become increasingly acidified. The effect of lower pH on marine organisms and ocean–atmosphere exchanges is largely unknown but organisms with CaCO3 structural components are likely to be particularly affected. Because calcifying phytoplankton are significant producers of dimethyl sulfide (DMS), it is vital to understand how lower seawater pH may affect DMS production and emission to the atmosphere. Here we show, by mesocosm (Raunefjorden, Norway, April–May 2003) and in vitro studies, that the net production of DMS and its cellular precursor dimethylsulfoniopropionate (DMSP) is approximately halved in microbial communities subjected to doubled CO2 levels. Our findings provide evidence that the amount of DMS entering the atmosphere could decrease in the future. Because atmospheric oxidation of DMS can lead to climate cooling by increasing cloud albedo, a consequence of reduced DMS emissions from a lower pH ocean would be an enhancement in global warming.

Social Marketing Campaigns

Quit and Win contests are social marketing campaigns that have met with great success in achieving smoking cessation. They have been organized in over 80 countries around the world, have had over 2 million smokers participate, and have helped an estimated 150,000 smokers quit. Quit and Win contests work by offering prize incentives and a supportive environment to smokers who wish to quit smoking. This article examines the structural components of Quit and Win programs that make them successful social marketing campaigns, along with the measures used to determine their success. Recommendations are provided for increasing the success of Quit and Win programs in the future. This review also provides useful lessons for the development of other types of social marketing campaigns.

Introduction. Developed communicative competence in the coaching profession allows to interact effectively in future professional activities, interpersonal communication and involves the subject’s mastery of strategies of psychological influence and constructive behaviors in interaction. Aim is to analyze different approaches to determining the structural components of communicative competence and to describe the author’s structure of communicative competence of the future coach. Material and methods. Theoretical - analysis, synthesis, generalization, systematization. Empirical- observations, questionnaires, psychological and pedagogical experiment. Results. Applying a systematic approach to the analysis of the structure of communicative competence, we identified four main components: cognitive (cognitive), communicative-speech, social-perceptual and interactive. Conclusions. The proposed and described author’s structure of communicative competence of the future coach contains four components: cognitive, communicativespeech, social-perceptual, interactive, which give the opportunity to reveal the essence and features of the future coach

Comprehensive Development

At the present stage of systematic identification and approbation, purposefulness and improvement of various methods in musicology and music-pedagogical levels of education, the creative development of the future music teacher appears as an integral part of his future professional competence. Creativity as well as performance influence the comprehensive development of an instrumentalist musician at any stage of learning. Creativity stimulates the student to extraordinary music lessons. The main form of work in the piano class is individual lessons, which should be considered as one of the leading links in the learning process. They create conditions for comprehensive education and upbringing of the student, allow to solve pedagogical tasks consistently, to develop creative initiative and independence. The analysis of musical and pedagogical literature allowed to single out the following structural components of professional and creative development of the future teacher of musical art in the course of classes in the class of the basic musical instrument (piano) as sensory-emotional, artistic and figurative and performing. The art of playing any musical instrument is based on the unity of artistic image and technical skill, which allows the musician to convey to the listener what he wants to express his performance. Constant improvement of technical skills is the musician's work to expand his capabilities in the embodiment of artistic images. Thus, the main task of organizing the learning process in the classroom of the main musical instrument (piano) is to train a competent, broad-minded music teacher who owns the instrument, with a developed need for independent, creative activity. Achieving this task is possible provided that the following structural components of professional and creative development of the student: sensory-emotional, artistic and performing.
