CHIBA MEDICAL JOURNAL

Instructions for Authors

1. Aims and scope

The Chiba Medical Journal is issued by the Chiba Medical Society, based at Chiba University, as an academic journal to publish outcomes of basic and clinical studies for medical life sciences.

2. Article types

We publish original articles (including short communications), case reports, review articles, lectures and essays. Articles that have been previously published or are under consideration for publication elsewhere will not be accepted.

3. Contributor qualifications

The first author and the corresponding author must be members of the Chiba Medical Society. The manuscript should be approved by all co-authors.
The Chiba Medical Journal endorses the International Committee of Medical Journal Editors (ICMJE) “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations)”. Submission of a manuscript to the Chiba Medical Journal implies that all authors have agreed to its content.

4. Peer review

Submitted manuscripts will be reviewed by members of the Chiba Medical Society or external experts. Authors are encouraged to suggest appropriate reviewers in the cover letter, although the Editorial Board will select the reviewers. Based on the reviewers’ evaluation, the Editorial Board will make the final decision of whether a manuscript is to be accepted, revised or declined.

5. Publication costs

Authors of submitted manuscripts must pay a publication fee in principle.
Color illustrations will be reproduced in the online publication at no additional cost to the author. Color in the printed version is optional, and the author will bear the full cost for color art reproduction. The color publication fees are listed on the journal's website.

6. Manuscript preparation

Articles should be written in standard English of sufficient quality to be understood. English editing is recommended for authors for whom English is not their first language.
We recommend that manuscripts, including figures and tables, are submitted as a single PDF file sent via electronic media such as an e-mail attachment or CD. For manuscript review and publication, we may request to submit original files for the text, figures and tables. The Cover Letter should be sent as a separate file. When electronic media is inconvenient, manuscripts can be submitted as paper copies.
Manuscripts should be formatted on A4 paper with 25 mm margins on all sides. The font should be 12 point Century or Times at ~25 lines per page.
