Manuscript preparation

Authors of submitted papers should familiarize themselves with ARTICLE SAMPLE (PDF)

The article should be structured  and  contain subsections:

  • Statement of the problem in general and its relationship with the current scientific and practical tasks;
  • Analysis of recent research and publications in which is started a solution of the problem;
  • Selection of the unsolved aspects of the problem, which is devoted to this article;
  • Formulation of the aims of article (problem);
  • Basic material with full justification of scientific results;
  • The conclusions of this study and the prospects for further research in this

To the article must be accompanied by:

  • An official letter signed by the head of the organization, in which the work was performed;
  • Two copies of the manuscript of the article made in accordance with the requirements set out. One copy of the manuscript should be signed by all the authors;
  • The original expert opinion on the possibility of the publication of this work in the press;
  • Signed by the Author's Agreement about the transfer of the author's right to publish a manuscript;
  • Full postal address one of the authors, contact telephone number and e-mail;
  • A copy of the subscription to the journal (from the organization or authors) - if available.

 Bioethical norms

The journal is oriented to directions recommended by European Convention for the protection of vertebrate animals used for experimental and other scientific purposes (Strasbourg, 1986), to directions of International Committee of Medical Journals Editors  (ICMJE) ( www.icmje.org), as well as “Bioethical expertise of preclinical and other scientific researches conducted on animals” (Kyiv, 2006). All procedures which describe experiments with the use of laboratory animals, any works with the use of materials obtained from humans or donors, and/or patients should be conducted being guided by the norms of bioethics. When describing experiments with animals, it is necessary to indicate what recommendations (national, institutional) concerning the work with animals were followed when performing the above procedures. If it is impossible to follow the particular norms, the author should substantiate the protocol change with its approval by the local Committee on Bioethics and define the corresponding­ changes in the section Materials and Methods.

Manuscript size, formatting and structure

The experimental work volume, including references, tables, figures with legends explaining obtained results (all on separate pages), should not exceed 20 pages A4 (40 000 printed characters), that of the reviews 30 pages (60 000 printed characters). The text type is Times New Roman type (type size 14, tables – type size 10; line spacing – 1.5).

 The manuscript structure

  •  UDC (Universal Decimal Classification)
  •  The paper title
  • The author’s (authors’) surname(s) and initials
  • The Institution where the work has been done
  • E-mail for correspondence
  • Summary and key words
  • Introduction
  • Materials and methods
  • Results and discussion
  • Conclusions
  • Acknowledgements
  • Data on financial support
  • References
  • Summary

Main investigation results are revealed in Summary in three languages should be structured and, no more than 250 words, and include the following sections:
– title;
– surnames and initials of all authors;
– text of the summary includes the work urgency, purpose, methods, results, conclusions;
– keywords (no more than 10 words).

  • Introduction (without title). The paper begins with the brief history of the problem with reference to sources and substantiation of the research objective.
  • Materials and Methods

The section Materials and Methods should present the description of the methods, reagents and experiment conditions in such a way that the experiment could be reproduced. The methods or methodology should be described only if they are distinguished by novelty or are of interest from the viewpoint of this work. Names of companies and countries producers of the reagents and materials used in the experiments should be given. The number and species of the used animals as well as the methods of anaesthetization and euthanasia should be defined.

Digital data should be rounded off due to the accepted rules, allowing for the average experiment error. The value difference authenticity should be substantiated by statistical analysis, citing the concrete methods. The same results should not be presented in Tables and Figures. The author should indicate the program used for statistical analysis of the obtained results, presentation of results, confidence interval or distribution of values.

All the designations and denominations of physical and chemical units of measurement should be given in SI system. If particular organisms (animals, plants, micro­organisms) used in the research are mentioned for the first time, their full species name in Latin (italicized) should be given in the paper text, follo­wing modern­ taxonomy; under the second mentioning the genus name should be denominated by one letter, except for the cases when genus names of different organisms begin with the same letter. Then, abbreviations of several letters are used, e.g., Staph. aureus, Str. lactis.

Word abbreviations, except for generally known ones, should not be given in Tables and Figu­re legends­ (with rare exception and then their interpretation in notes is obligatory). It is not worth giving arbitrarily abbreviated words, especially if they are brief. There is no point, for exam­ple, in abbreviating­ such words as peroxidase, glucosidase, etc.

  • Results and Discussion

In this section one should avoid the direct repetition of the table data. The result discussion should be limited by considering the most important established facts basing on preliminary data on the problem under study. In other words, the most part of the discussion should be devoted to results interpretation.

  • Conclusions (without title) may be accompanied by recommendations, estimations, proposals described in the paper.
  • References

References are composed due to the order of citing sources in the text (they are denominated by digits in square brackets) and are given at the paper end. References should include names of all authors of the paper, full title of the paper, abbreviated title of the journal, volume, periodical issue and pages. The titles of books (monographs, collected works, etc.) should be presented in complete form. One cannot refer to non-published materials. References must not contain any hyperlinks and/or URL. No more than 20 titles should be cited in experimental work, about 100 titles – in the survey. Works of the recent years should prevail in references.

Authors are completely responsible for correctness of references. Correct description of the used sources in References guarantees that the cited publication will be accounted for when determining the citing index.
