Title
The title should be short, specific, and informative which reflects precisely the content of the articles, maximum in 18 words written in English. The title followed by authors name, institutions and addresses and email.

Corresponding Author
Clearly indicate the name of corresponding author who will handle the correspondence during review process of article and also will be responsible for attending the queries of reviewer as well as the editor. The email address and phone number must be kept up to date for smooth interaction by the editor.

ABSTRACT
A concise and factual abstract is required including place of study/experiment, study year, objective and brief methodology. The abstract should state briefly principal results with data and major conclusions. An abstract is often presented separately from the article, so it must be and stand alone. Use of abbreviations should be avoided and the references should not be cited in the abstract.

Keywords
Immediately after the abstract, about 5-8 keywords should be given. Use of abbreviations should be avoided, only standard abbreviations, well known in the established area may be used, if appropriate. These keywords will be used for indexing.

INTRODUCTION
Provide a factual background, clearly defined problem, proposed solution, a brief literature survey and the scope and justification of the work done. Objective of study must be given at the end of introduction.

MATERIALS AND METHODS
Materials and methods include place of study, year of study and detailed methodology. It’s should be complete enough to allow experiments to be reproduced. However, only truly new procedures should be described in detail; previously published procedures should be cited, and important modifications of published procedures should be mentioned briefly. Capitalize trade names and include the manufacturer's name and address. Subheadings should be used. statistical methods used for data analysis be carefully and essentially stated with reference.

RESULTS
Results should be clearly described in a concise manner. Results for different parameters should be described under subheadings or in separate paragraph. Table or figure numbers should be mentioned in parentheses for better understanding. The results should be written in the past tense when describing findings in the author(s)'s experiments. Results should be explained, but largely without referring to the literature. The important and main findings of the study should come first in the Results Section. The tables, figures should be given in a sequence to emphasize the important information or observations related to the research. Tables & figures should be placed inside the text. Tables and figures should be presented as per their appearance in the text. Tables should be self-explanatory without reference to the text. The repetition of data in tables and figures should be avoided.

DISCUSSION
The discussion should not repeat the results, but provide detailed interpretation of data. This should interpret the significance of the findings of the work. Citations should be given in support of the findings. Results and Discussion could be given under one heading instead separately, if appropriate.

Conclusion
A small paragraph summarizing the contents of the article, presenting the final outcome of the research or proposing further study on the subject, may be given at the end of the article.

Acknowledgements
This section can be used to appreciate funders, institutions, and personals who assisted during research and articles preparation.

Authors’ contribution:
Authors will declare the contribution of each author. All authors interpreted the data, critically revised the manuscript for important intellectual contents and approved the final version.

Funding
The authors need to declare the funding sources of their manuscripts clearly by providing the name of the funding agency or financial support.

Ethics Approval

All manuscripts which deal with the study of animal subjects must be accompanied by Institutional Review Board or Ethical Committee Approval, or the national or regional equivalent. If a study is exempted from ethics approval, authors must indicate the reasons for exemption in the ethical statement.

REFERENCES
In each article whatever the category is, author(s) must ensure to cite at least 30% references of manuscripts published during the last five years. References before 1990’s are not allowed in the manuscript except in materials and methods section. Articles submitted for publication, unpublished findings and personal communications should not be included in the reference list but may be mentioned in the text (e.g., B. Toma, University of Michigan, USA, Unpublished results or personal communication). Every reference referred in the text must also present in the reference list and vice versa.
