• Figures: TIFF, PNG, or EPS at ≥ 300 dpi (≥ 600 dpi for line art); high-resolution vector originals preferred.
• Supplementary files: Standard formats (PDF, Excel, CSV, MP4); clearly labeled as Supplementary Table S1, Figure S1, etc.
• Cover letter: Uploaded separately as a PDF or Word document during portal submission.

Title Page & Author Information

The title page must be prepared with the following elements:

• Article Title: Concise, informative (max 20 words); should specify population, intervention, comparison, and outcome (PICO) where applicable.
• Author List: List all authors in contribution order, separated by commas. Affiliation format: Department, Institution, City, Postal Code, Country.
• Corresponding Author: Identified with an asterisk (*); include full name, academic degree, institutional postal address, phone, and official email.

• 4. Discussion: Interpretation in context of existing literature; biological mechanisms; translational significance; explicit study limitations; future directions.
• 5. Conclusion and Future Perspectives: Synthesis of principal findings; specific actionable research priorities (avoid generic "more research is needed").

Data Rigor & Research Integrity

Figures, Tables & Graphical Abstract

Graphical Abstract (Mandatory)

A visual summary of the main finding must accompany all Research Articles and Reviews. Dimensions: 1,100 × 560 px minimum (2,200 × 1,120 px max) at ≥ 300 dpi. Text within the image should not exceed 20 words.

Figures & Tables

Figures must be numbered sequentially (Figure 1, Figure 2). Multi-panel figures should be labeled A, B, C. Color figures are published free of charge. Tables must be submitted in editable Word format with concise titles above the table and statistical notes below.
