The primary criteria for acceptance and publication are scientific rigor and potential to advance the field.

Criteria for Manuscript

The over-riding criteria for publication are originality, high scientific quality and interest to a multidisciplinary audience. Papers not sufficiently substantiated by experimental detail will not be published. Any technical queries will be referred back to the author, although the Editors reserve the right to make alterations in the text.

Submitted manuscripts must meet the following criteria:

The material must be original
The writing must be clear, concise and unambiguous
The data are valid
The discussions and conclusions drawn by the authors must be reasonable
and supportable
The information must be relevant and interesting.

Manuscript Preparation

File preparation and types

Manuscripts are preferred in Microsoft Word format (.doc files). The following detailed instructions are necessary to allow direct reproduction of the manuscript for rapid publishing. Manuscript should be typewritten in Times Roman, 12 font size, double-spaced, title should be in a font size 14, bold face capitals, with margins of at least one inch on all sides. Tables and figures should appear in appropriate place of the main text. References should be given in Harvard style.

Manuscripts should be compiled in the following order:

Title page;
Main text;  
Declaration of interest statement;
Appendices (as appropriate);
Tables with captions (on separate pages);
Figures; figure captions (as a list).

Title Page

A title page should be provided comprising the manuscript title plus the full names and affiliations of all authors involved in the preparation of the manuscript. One author should be clearly designated as the corresponding author and full contact information, including phone number or mobile number and email address, provided for this person. Three to six key words that are not in the title should also be included on the title page. The keywords will assist indexers in cross indexing your article.  


Should start on a new page after the title page and should present the aim of the study, material and methods, results and conclusions, not more than 300 words. All the three categories, Review Articles, Research papers and Short Communications should have an Abstract.

Key Words

Three or more key words must be provided by authors for indexing of their article. Key words will be listed directly below the Abstract.


Should start on a new page and should clearly indicate the aim of the study.

Materials and Methods

Should start as a continuation to introduction on the same page.All important materials used along with their source shall be mentioned. The main methods used shall be briefly described,with references. New methods or substantially modified methods may be described in sufficient detail. The statistical method and the level of significance chosen shall be clearly stated.


All results presented in tabular or graphical form shall be described in this section. All Tables and figures must have a title and a legend to make them self-explanatory and they should be given numbers. Each table or figure should be on main body of the text.


should contain a critical review of the results of the study with the support of relevant literature. Unsupported hypothesis should be avoided.


This must summarize the main paper. Ensure that extrapolations are reasonable and that conclusions are justified by the data presented, and indicate if the study design can be generalized to a broader study population.


 All acknowledgments should be typed in one paragraph directly preceding the reference section.


Incorporate tables and/or figures with their legends into the main body of text.


The body of a review article should be a comprehensive, scholarly evidence-based review of the literature, accompanied by critical analysis and leading to reasonable conclusions. Wherever appropriate details of the literature search methodology should
be provided, i.e. the databases searched (normally Medline and at least one or two other databases), the search terms and inclusive dates, and any selectivity criteria imposed. Wherever possible, use primary resources, avoiding “Data on File”, “Poster” or other unpublished references.  

Acknowledgments and Declaration of Interest sections:

Acknowledgments and Declaration of interest sections are different, and each has a specific purpose. The Acknowledgments section details special thanks, personal assistance, and dedications. Contributions from individuals who do not qualify for authorship should also be acknowledged here.

Declarations of interest:

However, refer to statements of financial support and/or statements of potential conflict of interest. Within this section also belongs disclosure of scientific writingassistance (use of an agency or agency/ freelance writer), grant support and numbers, and statements of employment, if applicable. Please note: for Welcome-funded papers, the grant number(s) must be included in the Declaration of Interest statement.

Acknowledgments section :

Any acknowledgments authors wish to make should be included in a separate headed section at the end of the manuscript preceding any appendices, and before the references section. Please do not incorporate acknowledgments into notes or biographical notes.


References should be given in the Vancouver Style.In the Vancouver Style, citations within the text of the paper are identified by Arabic numbers in square brackets in [1]

The Vancouver System assigns a number to each reference as it is cited.A number must be used even if the author(s) is named in the sentence/text. e.g.Smith [10] has argued that...The original number assigned to the reference is reused each time the reference is cited in the text, regardless of its previous position in the text.

When multiple references are cited at a given place in the text, use a hyphen to join the first and last numbers that are inclusive. Use commas (without spaces) to separate non-inclusive numbers in a multiple citation e.g.[2,3,4,5,7,10] is abbreviated to [2-5,7,10].

Do not use a hyphen if there are no citation numbers in between that support your statement e.g. [1-2].

The placement of citation numbers within text should be carefully considered e.g. a particular reference may be relevant to only part of a sentence.  As a general rule, reference 3 numbers should be placed inside full stops and commas and inside colons and semicolons, however, this may vary according to the requirements of a particular journal.

Examples –

There have been efforts to replace mouse inoculation testing with invitrotests, such as enzyme linked immunosorbent assays [55,62] or polymerase chain reaction [22-24] but these remain experimental.Moir and Jessel maintain “that the sexes are interchangeable” [1].
