Submission Manuscript

All submissions manuscript should be formatted in the following sections:

  • All authors names and full addresses
  • Corresponding author’s postal and email address
  • A minimum of four keywords describing the manuscript 
  • Word count of the full article, excluding references and figure legends
Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
Author names and affiliations. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name.
Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.
Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
 

2. Abstract

The abstract should be a single paragraph of not more than 250 words, clearly stating the objective of the study or review, the methods used (where applicable), and summarizing results and conclusions.  Avoid abbreviations and references in this section.
Keywords
Immediately after the abstract, provide a maximum of 5 keywords and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
 

3. Introduction

The introduction should set the study in context by briefly reviewing relevant knowledge of the subject; follow this with a concise statement of the objectives of the study.
 

4. Materials and methods

Provide sufficient information for other workers to repeat the study. If well-established methods are used give a reference to the technique and provide full details of any modifications.
  • Include the source of chemicals, reagents and hormones and give the manufacturer’s name and location (town, country) in parentheses.
  • Give the generic name, dose and route of administration for drugs.
  • Specify the composition of buffers, solutions and culture media.
  • Use SI symbols, give concentrations in mol/L and define the term % as w/v or v/v for all solutions. For international units use IU (U should be used for enzyme activity).
  • Specify the type of equipment (microscopes/objective lenses, cameras, detectors) used to obtain images.
  • Specify any image acquisition software used, and give a description of specialized techniques requiring large amounts of processing, such as confocal, deconvolution, 3D reconstructions, or surface and volume rendering.
 

5. Results

 Results should be clear and concise.

6. Discussion 

This should explore the significance of the results of the work, not repeat them. Avoid extensive citations and discussion of published literature.

Figure captions
Ensure that each illustration has a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Tables

Please submit tables as editable text and not as images. Tables can be placed either next to the relevant text in the article, or on separate page(s) at the end. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article.
