Author Guidelines

General Standards

Language Editing

Biomedical Research and Theory Letters (BRTL) requires manuscripts submitted to meet international standards for the English language to be considered for publication. Articles are normally published only in English. For authors who would like their manuscript to receive language editing or proofing to improve the clarity of the manuscript and help highlight their research, BRTL recommends the language‑editing services provided by internal or external partners (contact the Principal of BRTL for further information). Note that sending your manuscript for language editing does not imply or guarantee that it will be accepted for publication by BRTL. Editorial decisions on the scientific content of a manuscript are independent of whether it has received language editing or proofing by the partner services, or other services.

Language Style

The default language style at BRTL is American English. If you prefer your article to be formatted in British English, please specify this on your manuscript on the first page.

Search Engine Optimization (SEO)

To maximize your article’s discoverability, follow these steps:

  • Include a few of your article’s keywords in the title.

  • Avoid long article titles.

  • Pick 3–5 keywords using a mix of generic and specific terms.

  • Use keywords in the first two sentences of the abstract.

  • Use some keywords in level 1 headings.

Title

The title is written in title case, aligned to the center, and in Cambria font at the top of the page. It should be concise, avoid abbreviations, and reflect the main result or conclusion.

Authors and Affiliations

All names are listed together and separated by commas. Affiliations should be keyed to the author’s name with superscript numbers and listed as: Institution/University/Organization, Country. Example: Universitas Islam Negeri Raden Intan Lampung, Indonesia. Corresponding authors should be marked with superscript and provide exact contact email addresses.

Headings and Sub‑headings

  • Headings: Cambria, 14 pt, bold, sentence case.

  • Subheadings: Cambria, 10.5 pt, bold, capitalize each word.

Abstract

  • Maximum 250 words, written in English using Cambria, 9 pt.

  • Should include background, aims, methods, summary of results, and conclusions.

  • Keywords: 3–5 mandatory.

Text

  • Body text: Cambria, 11 pt, single‑spaced.

  • Include page and line numbers to facilitate review.

Sections

Manuscripts should be organized into:

  • Introduction

  • Methods

  • Results and Discussion

  • Conclusion

  • Acknowledgments (if any)

  • Author Contributions Statement

  • References

Figures and Table Guidelines

General Style Guidelines for Figures
Figures help readers visualize the information you are trying to convey. Often, it is difficult to be sufficiently descriptive using words. Images can help in achieving the accuracy needed for a scientific manuscript. For example, it may not be enough to say, "The surface had nanometer-scale features." In this case, it would be ideal to provide a microscope image.
For images, be sure to:
  • Include scale bars
  • Consider labeling important items
  • Indicate the meaning of different colors and symbols used
General Style Guidelines for Tables
Tables are a concise and effective way to present large amounts of data. You should design them carefully so that you clearly communicate your results to busy researchers.
The following is an example of a well-designed table:
  • Clear and concise legend/caption
  • Data divided into categories for clarity
  • Sufficient spacing between columns and rows
  • Units are a provided font type and size are legible
Figure and Table Requirements
Legends
Figure and table legends are required to have the same font as the main text (11 points normal Cambria, single-spaced). Legends should be preceded by the appropriate label, for example, "Figure 1" or "Table 4". Figure legends should be placed at the end of the manuscript (for supplementary images you must include the caption with the figure, uploaded as a separate file). Table legends must be placed immediately before the table. Please use only a single paragraph for the legend.
 
Image Size
Figure images should be prepared with the PDF layout in mind, individual figures should not be longer than one page and with a width that corresponds to 1 column or 2 columns.
 
Format
The following formats are accepted:
TIFF (.tif) TIFF files should be saved using LZW compression or any other non-lossy compression method. JPEG (.jpg)
EPS (.eps) EPS files can be uploaded upon acceptance
 
Colour Image Mode
Images must be submitted in the color mode RGB.
 
Resolution Requirements
All images must be uploaded separately in the submission procedure and have a resolution of 300 dpi at final size. Check the resolution of your figure by enlarging it to 150%. If the resolution is too low, the image will appear blurry, jagged or have a stair-stepped effect.
Please note saving a figure directly as an image file (JPEG, TIF) can greatly affect the resolution of your image. To avoid this, one option is to export the file as PDF, then convert into TIFF or EPS using a graphics software. EPS files can be uploaded upon acceptance.
Details of all funding sources must be provided in the funding section of the manuscript including grant numbers, if applicable.

References

  • Follow APA 7th Edition style.

  • Use reference management tools (Mendeley, Zotero).

  • Include DOI or retrieval link when available.
