Author Guidelines

Organization of the manuscript

General formatting

The submitted manuscript must be typed double-spaced throughout and numbered (including references, tables and figure legends). Preferably using a “standard” font (we prefer Times/Arial 12). For mathematical symbols, Greek letters, and other special characters, use normal text. The references must be in accordance with the Journal of Gerontology and Geriatrics reference style (see References).
Approved nomenclature for gene and protein names and symbols should be used, including appropriate use of italics (all gene symbols and loci, should be in italics) and capitalization as it applies for each organism’s standard nomenclature format, in text, tables, and figures. Full gene names are generally not in italics and Greek symbols are not used. Proteins should not be italicized.
Improperly prepared manuscripts will not be entered into the peer review process and will be sent back to the author for correction.
A letter of submission must be uploaded with all manuscripts. This letter may be used to outline the strengths of the manuscript. All commercial relationships (i.e. consultancies, patent-licensing agreements) that might pose a conflict of interest in connection with the submitted manuscript must be included in the letter.


The JGG uses the reference style as outlined in the  ICMJE sample references, also referred to as the “Vancouver” style.

References must be listed at the end of the manuscript and numbered in the order that they appear in the text.

In the text, citations should be indicated by the reference number in brackets.

If an article is submitted to a journal and also publicly available as a pre-print, the pre-print may be cited.

Journal name abbreviations should be those found in the NCBI databases.


Reference formatting


Because all references will be linked electronically as much as possible to the papers they cite, proper formatting of the references is crucial. References should be formatted as follows:


Published papers

Note: Use of a DOI number for the full-text article is acceptable as an alternative to or in addition to traditional volume and page numbers:

Accepted, unpublished papers

Same as above, but “In press” appears instead of the page numbers or DOI.

Figures and Tables.

Figures. All graphics submitted to the JGG should be sent at their actual size, which is 100% of their print dimension and in portrait orientation.

Two standard widths are used and figures should fit in one (8.5 x 23.5 cm) or two (17.5 x 23.5 cm) columns.

Figures should be supplied in the following preferred file formats: PDF (*.pdf), Power Point (*.ppt), Adobe Illustrator (*.ai, *.eps), Photoshop (*.psd) files in grayscales or in RGB color mode.

Photographs (scans, immunofluorescences, EM, and histology images) should be submitted as: 1) TIFF (*.tif) with a resolution of at least 300 pixels per inch, or 2) Illustrator compatible EPS files with RGB color management (*.eps), 3) Photoshop (*.psd) or PDF (*.pdf) files (grayscales or RGB) at the appropriate resolution which is:

  • * 300 dpi for color figures
  • * 600 dpi for black and white figures
  • * 1200 dpi for line-art figures

For all photomicrographs, where possible, a scale should appear on the photograph. Photographs of identifiable patients should be accompanied by written permission to publish from patient(s).

Furthermore, panel lettering should be in Arial bold 14 pt, capitalized and no full stop (A, B) while lettering in figures (axes, conditions), should be in Arial 8 pt, lower case type with the first letter capitalized and no full stop. No type should be smaller than 6 pt. (For more detailed information, please refer to the Figure and Table Guidelines).

If after acceptance the quality of the figures does not match the standards of the Journal, the authors will be asked to resubmit the figures at the required quality.
Tables. Tables should be provided as Word files (*.doc) or Illustrator/InDesign (*.ai, *.eps, *.indd) compatible files. No TIFF and JPG files are acceptable for table submission. When submitting tables in Microsoft Word table function, no tab, space or colors should be used. Tables should contain a maximum of 10 columns. Tables submitted in landscape orientation will not be accepted. Tables should include a title, table legend, and if necessary footnotes. Include tables in the submitted manuscript as a separate section.
Figure Legends. Figure legends should be listed one after the other, as part of the text document, separate from the figure files. Please do not write a legend below each figure. Each figure legend should have a brief overarching title that describes the entire figure without citing specific panels, followed by a description of each panel, and the symbols used. Enough information should be provided in the figure legend text to permit interpretation of figures without reference to the text; but should not contain any details of methods, or exceed 100 words.
The abbreviated word for figure “Fig.” should be typed and bolded, followed by the figure number and a period (i.e.., “Fig. 1.”). Every figure legend should have a Title written in bold. If a figure contains multiple sections (i.e. A, B, C, D) the letter for these subsections should be in capital letters. Within the figure legend text the capital letters should be surrounded by parenthesis [i.e. (A)(B)(C)(D)]. Figures should be numbered according to the order of citation.

Supplementary material.
Supplementary material can be uploaded during the submission process.
The Supplementary material should have a manuscript title, list of authors, a table of contents, followed by the list of investigators (if there is one), text (such as methods), figures, tables, and then references. Supplementary material must be prepared as a single Word file with pages numbered (including references, tables and figure legends) using Times New Roman or Arial 12 pt double-spaced). Sections have to be 12 pt bold, Subsections have to be 12 pt, italics. For mathematical symbols, Greek letters, and other special characters, use normal text, NOT symbol. The references must be in accordance with the Journal of Hepatology reference style (see References).
Figures have to be included with legends below each figure. Figure legends consist of a title (bold) and separate descriptions for reach panel, labelled by capital letters in parenthesis. Tables have to be included with Table titles (bold) on top of the Table and footnotes below. Very large Tables (e.g., microarray data) should be submitted as Excel file.
The Supplementary material will not be edited for style.
Supplemental movies may be submitted through Elsevier Editorial System as (*.mov), (*.avi), (*.mpeg), or (*.gif) files. By choosing the submission item labeled “Supplementary data,” the PDF builder will imbed links within the PDF where editors and reviewers will be able to download the files. This also works for Excel files that do not display properly once converted to a PDF. Please note that the size limit for these items is 10 MB per file.
Large data sets (too large to be included within the manuscript) must be submitted online. Each file should be prepared as PDF, Excel, or text. The size of the file should not exceed 10MB.
Upon acceptance, if supplementary material does not comply with the guidelines authors will be requested to change the formatting.


SIGG- Società Italiana di Gerontologia e Geriatria and Pacini Editore srl inform readers and users of the Journal of Gerontology and Geriatrics, that the published articles reflect only the research and the opinion of the authors signing the contents. These articles therefore do not represent and do not in any way constitute indications or guidelines of the SIGG itself. This differs from the texts and contents that are explicitly declared as official institutional matrix and published in the appropriate sections of the Journal, which are dedicated to the Guidelines of SIGG.


Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.

  1. The submission file is in OpenOffice, Microsoft Word, RTF, or WordPerfect document file format.
  2. Where available, URLs for the references have been provided.
  3. The text is single-spaced; uses a 12-point font (we prefer Times/Arial); employs italics, rather than underlining (except with URL addresses); and all illustrations, figures, and tables are placed within the text at the appropriate points, rather than at the end.
  4. The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines, which is found in About the Journal.
