Original Research articles are peer-reviewed, have a maximum word count of 7,000, and may contain no more than 8 Figures/Tables. Authors are required to pay a fee (A-type article) to publish an Original Research article. Original Research articles should have the following format: 1) Abstract, 2) Introduction, 3) Materials and Methods, 4) Results, 5) Discussion.

Methods

Methods articles present either a new or established method, protocol, or technique that is of significant interest in the field.
