Keep the INTRODUCTION brief, stating clearly the purpose of the article and its relation to other papers on the same subject. Do not give an extensive review of literature. Provide enough information in the MATERIAL AND METHODS section to enable other investigators to repeat the experiments. Report RESULTS clearly and consistently. Do not present the same results in tables and illustrations. Exceptionally, results and discussion can be combined in a single section. In the DISCUSSION interpret the results, state their meaning and draw conclusions. Do not simply repeat the results.
