Journal article (without DOI): Costa MB, Farias IR, da Silva Monte C, Filho LIPF, de Paula Borges D, de Oliveira RTG, Ribeiro-Junior HL, Magalhães SMM, Pinheiro RF. Chromosomal abnormalities and dysregulated DNA repair gene expression in farmers exposed to pesticides. Environ Toxicol Pharmacol. 2021 Feb;82:103564.

Journal article (with DOI): de Oliveira RTG, Cordeiro JVA, Vitoriano BF, de Lima Melo MM, Sampaio LR, de Paula Borges D, Magalhães SMM, Pinheiro RF. ERVs-TLR3-IRF axis is linked to myelodysplastic syndrome pathogenesis. Med Oncol. 2021 Feb 17;38(3):27. doi: 10.1007/s12032-021-01466-1.

Acknowledgments: Acknowledgments of people, grants, funds, etc. should be placed in a separate section after the references section.

Conflict of interest: Any conflict of interest should be placed in a separate section after the acknowledgments section. As criteria for conflict of interest, we used the concept reported by The International Committee of Medical Journal Editors, which reinforces that Authors should avoid entering into agreements with study sponsors, both for-profit and non-profit, that interfere with authors’ access to all of the study’s data or that interfere with their ability to analyze and interpret the data and to prepare and publish manuscripts independently when and where they choose. Thus, all authors must disclose all relationships or interests that could inappropriately influence or bias their work.

Funding: All sources of funding of the study should be disclosed in a separate section after the conflict of interest section.

Plagiarism is expressly prohibited in BJCR submissions. Plagiarism includes copying text, ideas, images, or data from another source, even from your own publications, without giving any credit to the original source. BJCR reserves the right to hire a plagiarism check service if it identifies textual or data abnormalities in the manuscript submission.

The BJCR recommends the use of statements, checklists and flowcharts for awareness of authors in relation to the development of your study (e.g., CARECONSORT, STARD, STREGA, PRISMA, SQUIRE, COREQ, ENTREQ, CHEERS, and SAMPL).

More structural details of each article type are described in the sections below (last modified January 2022).
