An essential element of the journal “Bulletin of Problems in Biology and Medicine” is compliance with the principles and provisions on conflicts of interest between the author-reviewer-editorial board. Public confidence in the objective review process and the quality of publications largely depends on the extent to which possible conflicts of interest are considered during the review process and when deciding on publication. A conflict of interest may arise if a reviewer, member of the editorial board, or editorial staff member has a relationship with a person who may subjectively influence the decision to publish. The reasons for conflicts may include relations with an employer, family relationships, financial interests, as well as academic competition, personal likes or dislikes, etc. Therefore, the journal requires that all authors and reviewers declare any existing or potential conflict of interest that may affect the decision to submit and prepare a manuscript for publication.
