Editorial and Publishing Policies


Author Communication

Communication with the journal editor can be conducted by the corresponding author on behalf of all co-authors. The corresponding author takes responsibility for coordinating all communication before and after publication. The copyright form is sent to the corresponding author for signing.

Authorship Sequence and Changes

The authors should agree on the authorship sequence and affiliations mentioned in the manuscript. Any changes to the authorship list, including additions or deletions, require approval from all authors involved. If disputes regarding authorship arise, they should be resolved among the authors, but if necessary, the case can be brought to the editors. We follow the guidelines of the Committee on Publication Ethics (COPE) for addressing disagreements.

Data Responsibility

The corresponding author is responsible for ensuring the originality and preservation of the data submitted. During the review process, all data files should be provided for evaluation.

Contribution Statement

We recommend including a statement specifying the individual contributions made by each author. The details may vary based on the manuscript category and the nature of the work, whether conducted individually or as a group. This statement will not be published in the print or online version.

Corresponding Author's Role

The corresponding author holds prepublication responsibilities, such as ensuring all authors are included in the list and verifying their agreement with the authorship sequence. Administrative requirements must be met, and the manuscript should not be under consideration or published elsewhere.

Responsibilities After Acceptance

Once the final copy-proof is received, the corresponding author is responsible for circulating it among co-authors and liaising with the journal on their behalf. Changes requested after publication will not be considered for mistakes previously approved in the copy-proof. The corresponding author ensures the accuracy of names, correct spellings, addresses, and affiliations for all co-authors.

Responsibilities After Publication

Any correction or alteration to the published article requires the consent of all co-authors. If there are dissenting authors, the corresponding author should include a statement reflecting the correspondence with them. COPE guidelines are followed for addressing disagreements between authors.

 Acknowledgment of Contributors

Contributors who are not listed as authors should be mentioned in the acknowledgment section, with a clear description of their specific contributions to the study.

Alteration to Authorship or Contributorship

Changes to Authors or Contributors: Initially, after submission, requests for changes in authors or contributors, including additions, deletions, or changes in order, will be considered. However, approval from all authors is required. The editor must be informed and provided with a clear explanation of the alterations. In exceptional circumstances, changes after acceptance may be considered, and COPE guidelines are followed for changes after publication.

Confidentiality of Communication

CATHALOGUE maintains the confidentiality of authors and reviewers. All communication between authors and editors is treated as confidential. Authors are expected to maintain the confidentiality of the manuscript before publication and avoid publicizing review reports or related materials without prior permission. Unauthorized publication may result in manuscript rejection.

Referee Suggestions

We appreciate your suggestions for potential reviewers, but please note that the selection of peer reviewers is ultimately determined by the editors. However, we are open to considering exclusion requests, if any.

Consortia Authorship

CATHALOGUE supports consortium authorships. In such cases, we recommend explicitly identifying the members of the consortium who agree to take responsibility as authors separately from those who do not.


Copyrights & Permissions

CATHALOGUE adheres to the CC BY 4.0 license (Creative Commons Attribution 4.0 International License). Please refer to the full license legal code for detailed information. For open-access publishing, we employ a non-exclusive licensing agreement. Authors retain the copyright and primary scholarly usage rights while granting the journal publication and distribution rights. This allows maximum utilization and exposure of the work while ensuring proper credit to the original source. The journal follows COPE Guidelines to address issues such as systematic manipulation, plagiarism, duplicate publications, and redundant or overlapping content.

  • It is important to obtain permission from the copyright holder (either the author(s) or publisher) before using material from previously published scholarly work. This applies to:
  • Your own work where the copyright holder is the publisher.
  • Extensive use of another work, beyond limited portions, which necessitates permission from the copyright holder.
  • Usage of unaltered or slightly altered tables, graphs, and artwork (whether self-authored or by another copyright holder), which requires permission.
  • Completely redrawn and reconstructed tables, graphs, charts, and artwork with proper citation of the source do not require permission.
  • CATHALOGUE offers open access to its journal content without subscription charges. The journal is self-financed and does not receive funding from external sources. Publication processing is solely dependent on the publisher's personal funds. The content is freely accessible to readers on the journal's website.


Post-Publication Critiques

CATHALOGUE encourages post-publication discussions through letters to the editor, commentaries, and other types of correspondence. The journal has established mechanisms to correct, revise, or retract articles after publication, following COPE's core practices.


Image Integrity and Standards

Authors are advised to retain unformatted files, including raw data and metadata, of the submitted manuscript as they may be requested during the evaluation process. Failure to provide missing data files may result in delays in evaluation and publication. When submitting the final revised manuscript, high-quality images with a minimum resolution of 300 dpi for colored images, 600 dpi for grayscale images, and 1200 dpi for line art should be included.

Authors should minimize image formatting and ensure that each image clearly presents the results. The following instructions should be followed for image processing:

  • Clearly specify the image processing tools, software packages, image acquisition techniques, and settings used in the methodology section.
  • If images are compiled from different sources to create a composite image representing a time-lapse sequence, ensure that the borders of each image are well-defined and labeled within the figure legend.
  • Avoid using cloning and healing tools in software like Photoshop.
  • Refrain from excessive processing, such as manipulating image contrast to emphasize a particular region of the displayed results. Minor adjustments in brightness and contrast across the entire image for visibility are acceptable.
  • Authors may be requested to provide unprocessed images upon final submission, so it is crucial to retain the raw data.


When presenting microscopic images, it is highly recommended that authors include multiple supporting fields rather than juxtaposing multiple cells into a single field. This approach provides readers with a better understanding of the subject. All adjustments made to the images should be applied uniformly across the entire image, and manipulation of signal ranges should be avoided.

Checklist for Image Processing

The methodology section of the final submitted manuscript should include the following details regarding image processing:

  • Types of tools and acquisition software used for image processing, such as microscopes, objective lenses, cameras, detectors, and filter models.
  • Disclosure of any manipulations performed on the final image.
  • Initial resolution at which the image was captured.
  • Description of any image processing conducted to enhance resolution.

Image Manipulation

If readers or reviewers suspect any image manipulation, the corresponding author should be notified via email. The author will be given an opportunity to provide an explanation. If the manipulation is unsatisfactorily addressed or admitted by the author, the manuscript may be retracted. In cases where the majority of the work is original and only minor manipulation occurred, the author may be requested to submit alterations. Failure to comply with this request may result in retraction.


Plagiarism Policy

Plagiarism involves the act of stealing ideas, text, or results from others and presenting them as one's own. CATHALOGUE does not consider manuscripts that contain substantial copy-pasted data or plagiarized content.

Plagiarism in a Submitted Manuscript:

If plagiarism is identified in an article under consideration in CATHALOGUE, it will be investigated in accordance with the instructions provided by the Committee On Publication Ethics (COPE). Authors will be given an opportunity to explain and justify their actions. If the response is unsatisfactory, the article will be retracted, and a notice of retraction will be published online and in the next printed issue of the journal.

Plagiarism in a Published Article:

If plagiarism is discovered in a published article, the Journal may publish a retraction according to COPE guidelines, especially if the author fails to provide a satisfactory explanation.

Duplicate Publication:

Material submitted to CATHALOGUE must be original and not under consideration elsewhere for publication, unless the corresponding author has received a rejection letter for the respective manuscript. Partial publication of work from a Ph.D. or thesis is encouraged in CATHALOGUE.

If the author wishes to submit a contribution that has already been published or is under consideration elsewhere, this must be disclosed in the cover letter. Such manuscripts will only be considered if the results and conclusions differ from the previously published study. Complete copyright details from the previous publisher must be provided if reusing a figure that has already been published elsewhere.



Crossmark is an initiative that provides readers with a standardized way to locate the current version of a document. By using the Crossmark button, CATHALOGUE commits to maintaining the content it publishes and informing readers of any changes.

Clicking on the Crossmark button will provide the current status of a document and additional publication record information.


Research Ethics

CATHALOGUE adheres to strict ethical standards for research involving human subjects. Authors must confirm that their submitted manuscripts comply with the ethical guidelines provided by the International Committee of Medical Journal Editors (ICMJE). Specifically, authors must ensure that the research was conducted in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and the Helsinki Declaration of the World Medical Association, including all current revisions and amendments. Authors may be requested to provide evidence of ethical approval, and the manuscript should clearly state the involvement of the institutional review board. The process of obtaining informed consent from the subjects must be clearly described in the manuscript.

Clinical Trial Registration

Clinical trials must be registered prior to patient enrollment in accordance with the ICMJE criteria. Registration can be done via platforms like www.clinicaltrials.gov or similar agencies. Trials focused solely on determining the pharmacokinetics of a drug are exempt from this requirement.

Publishing Images from Human Research Participants

If a manuscript includes images of human subjects (e.g., case images), it must be accompanied by a clear statement affirming that the patient was informed and gave consent for the inclusion of their images in the manuscript. Confidentiality must be maintained, and patient identity should not be disclosed. The editors may request the authors to provide the consent form, and failure to provide satisfactory evidence may result in the removal of the images from the manuscript without further notice.

Scientific Misconduct

CATHALOGUE takes all possible measures to prevent scientific misconduct. Submitted articles undergo internal evaluation by the editorial team, and if any concerns arise regarding misconduct in research or publication, the assigned editor discusses the case with the board members and the ethical committee. If the issue remains unresolved and the author fails to provide a satisfactory justification, the specific manuscript may be rejected.


Communication with the journal editors regarding a manuscript does not require the involvement of all authors. The corresponding author, as designated by the authors themselves, is responsible for all communication with the journal. By signing the copyright statement, the authors confirm the current authorship sequence, affiliations, and their agreement to submit the manuscript to CATHALOGUE. Any changes to the authorship sequence, including the addition or removal of authors, requires approval from each author involved. It is recommended to report such changes before publication.

Competing Interests

Authors must disclose all competing interests, both financial and non-financial, at the time of manuscript submission. These competing interests can potentially undermine the originality of the work and the authors' contributions to data presentation, analysis, and interpretation. The corresponding author is responsible for submitting a statement on behalf of all co-authors regarding conflicts of interest.

Plagiarism Policy

Plagiarism, including the incorporation of others' ideas, text, or results without proper attribution, is strictly prohibited. Manuscripts with substantial copy-pasted content or plagiarism will not be considered for publication. If plagiarism is identified in an article under consideration, the authors will be given an opportunity to explain their actions. However, if the response is unsatisfactory, the article may be permanently retracted, and a notice of retraction will be published online and in the next printed issue of the journal.

Duplicate Publication

Material submitted to CATHALOGUE must be original and not simultaneously under consideration elsewhere, unless the corresponding author has received a rejection letter for the respective manuscript. Publishing a part of work from a Ph.D. or thesis in CATHALOGUE is encouraged.


Patient Consent

For studies involving human subjects, informed consent must be obtained for the presentation of personal characteristics. Alternatively, the patient identity must be fully anonymized. CATHALOGUE strongly recommends obtaining patient consent to avoid the loss of evidence and essence of the case.

Children or Patients with Inabilities

If the research involves children under 18 years of age or patients lacking the mental or physical capacity to understand the purpose of publication, consent can be obtained from parents or guardians. It is essential to ensure the comfort and willingness of the individual to be published, as future disclosures of personal details may affect them negatively.

Case Images

Publication of images such as X-rays, ultrasound images, pathological slides, or organ/part images does not require consent. Consent is only necessary when presenting identifiable images or details.

Image Anonymization

Images should be appropriately cropped to show only the relevant clinical features related to the study. Obscuring images with hidden or blurred eyes is not preferred, as it may indicate misconduct or the publication of data without patient permission.

Consent Form

To include identifying information, authors must provide a signed consent form from the patient, confirming their agreement to use the information as per the Consent Form for Publication in CATHALOGUE.


Confidentiality and Pre-publicity

At CATHALOGUE, we prioritize the confidentiality of the editorial and peer review process. Editors, authors, and reviewers are required to maintain strict confidentiality throughout the entire process. Our review process is conducted anonymously through double-blind peer review, ensuring that the identities of reviewers and authors are not disclosed. Reviewers are prohibited from discussing the submitted manuscript with anyone unless authorized by the Editor. Similarly, authors are expected to refrain from publicizing details about their manuscript until publication.


We strongly advise authors not to discuss their work with the media or other journals before publication. If a manuscript under consideration at CATHALOGUE is leaked to the press or media prior to publication, we reserve the right to investigate the matter. Our editors will assess the authors' cooperation with journalists during this process, and the final decision will be based on the editors' judgment. If our journal policies are violated, the manuscript may be rejected, regardless of any media coverage it may have received.

Presentations and Abstracts

Authors are permitted to present the material submitted to CATHALOGUE at scientific meetings. Additionally, authors are free to present abstracts in conference proceedings. Contributions submitted to the journal may also be posted on websites, such as wikis or the author's blog. However, the author must provide the website name and URL in the cover letter accompanying the submitted manuscript to the editor.


Competing Interests

CATHALOGUE requires authors to disclose all competing interests, whether financial or non-financial, at the time of submission. These competing interests have the potential to influence the originality of the work and the authors' contributions to data presentation, analysis, and explanation. The corresponding author is responsible for submitting a statement regarding conflicts of interest on behalf of all co-authors.

Financial Competing Interests

Financial competing interests include funding received for the specific publication, employment in organizations affected by the publication, and personal financial gains or losses related to the publication. Authors must disclose the role of funders in study design, data collection, analysis, and manuscript preparation. Any personal financial interests, such as stock ownership, consultation fees, or reimbursed fees from organizations affected by the publication, must also be disclosed. In the case of patent applications related to the manuscript, detailed information should be provided.

Non-financial Competing Interests

Non-financial competing interests encompass personal, religious, academic, political, and professional associations that may influence the publication process. Authors and referees are encouraged to disclose such relationships that could impact the evaluation and review of the manuscript.

Application to Reviewers and Editors

We request that peer reviewers disclose all financial and non-financial competing interests before accepting a review opportunity. This information assists the editors in selecting appropriate reviewers. Similarly, editors themselves must disclose any existing competing interests that may affect their editorial duties.


Peer Review Policy

CATHALOGUE follows a comprehensive peer review process for all types of articles. We uphold rigorous standards to ensure the scientific integrity and quality of published work. Here is an overview of our peer review policy:

Criteria for Publication

All articles submitted to CATHALOGUE undergo peer review. Original Research articles present scientific research that aligns with our editorial policies. The experiments, analysis, and statistical methods should adhere to technical standards outlined in our journal guidelines, with clear and detailed explanations. We encourage the use of simple language and concise phrases. It is crucial that the content submitted has not been published elsewhere. If the results have been presented as an abstract in a conference, this information should be declared at the time of submission.

Peer Review Model

To maintain the anonymity of both authors and reviewers, CATHALOGUE employs a double-blind peer review policy for all submissions. Authors are responsible for anonymizing their manuscript, removing any details that may reveal their identity. Conflicts of interest should be disclosed within the cover letter. While authors are encouraged to acknowledge all contributors, specific details should only be shared in the cover letter to ensure the integrity of the blind peer review process.


To ensure timely publications, reviewers are requested to respond within the designated review period for each manuscript. If there are delays, reviewers are encouraged to inform the journal editor promptly. This allows us to communicate the status to the authors and explore alternative options if necessary.

Review Process

Upon submission, manuscripts undergo an initial review by the staff editors. Papers that meet our editorial criteria are sent for formal review. Those deemed of insufficient general interest or otherwise inappropriate are promptly rejected without external review or may be returned to the author for revision. Manuscripts considered to have potential interest for our readership are typically sent to two or three reviewers. The editors make a decision based on the reviewers' advice, which may include:

  • Acceptance with or without editorial revisions
  • Acceptance with the suggestion that further work may warrant resubmission
  • Rejection based on factors such as specialist interest, lack of novelty, insufficient conceptual advance, or major technical and/or interpretational problems

Selection of Peer Reviewers

Reviewers play a vital role in the peer review process. The editorial decision heavily relies on their comments and expertise. After passing the in-house check, the editorial board selects reviewers based on their relevance to the article's topic and their reputation and past experience with CATHALOGUE. Reviewers are expected to treat the articles with strict confidentiality during the review process.

During the review, reviewers should provide expert opinions on various aspects of the manuscript, including study design, methodology, statistical analysis, and technical details. It is essential for reviewers to evaluate the study from an international perspective, considering its main results in the context of existing literature. Reviewers should also ensure that references comply with CATHALOGUE's guidelines and are listed unambiguously. In addition to technical considerations, reviewers are encouraged to provide feedback on general issues, such as language clarity, rationality of the topic's treatment, inclusion of a comprehensive study background, and more.

Efficient and timely feedback from reviewers is crucial for the prompt processing of articles and timely response to authors. Reviewers are expected to adhere to the agreed-upon deadlines. The comments provided by reviewers are communicated to authors without editing. Such communication is essential for improving the manuscript. The paper is not accepted until reviewers are satisfied with the authors' explanations.

If a reviewer is unable to fulfill their commitment, the editorial board reserves the right to exclude them from the CATHALOGUE panel without prior notice.

Peer Review Policy for Editors, Employees, or Editorial Board Members

CATHALOGUE maintains the same peer review policy for Editors, Employees, or Editorial Board Members submitting their work to the journal as for other authors. To mitigate biases in the peer review process, manuscripts from editors or board members are assigned to associate editors without identifiable information. These manuscripts then undergo review by 2-3 independent reviewers.


Publication License

CATHALOGUE operates under the CC BY 4.0 license (Creative Commons Attribution 4.0 International License). For specific details, please refer to the complete license legal code. In terms of open access publishing, CATHALOGUE utilizes a non-exclusive licensing agreement. Authors retain the copyright and primary scholarly usage rights, while granting the journal publication and distribution rights.


Complaints and Appeals

While appeals are not given the highest priority, we value your opinion, and a compelling appeal may lead to reconsideration. If you have concerns or wish to file a complaint or appeal regarding an editorial decision or the journal's competence (such as rejection, review duration, or conduct of researchers, authors, or reviewers), please register your complaint via email, providing a detailed description of your concerns. We will investigate the matter in accordance with the guidelines set forth by the Committee on Publication Ethics (COPE) and discuss it in the editorial board meeting.


Scientific Misconduct

We take scientific misconduct seriously and adhere to COPE guidelines to prevent such occurrences. Submitted articles undergo an initial internal evaluation by the editorial team. If any concerns arise regarding potential research or publication misconduct that could impact the journal's ethical policies, the assigned editor, upon the Chief Editor's recommendation, discusses the case with the ethical committee and other board members. If the issue remains unresolved after discussion with the author, it may result in the rejection of the manuscript.

If, during the review process, a reviewer identifies data fabrication, duplicate publication, or ethical concerns related to a manuscript (such as ethical approval or patient consent), they will notify the handling Editor. The handling Editor will conduct an investigation, and if the claim is substantiated and the authors fail to provide a satisfactory explanation, the manuscript will be immediately rejected without further notice.

Data Fabrication, Falsification, and Retraction

Data fabrication, falsification, including deceptive image manipulation, and plagiarism are considered serious breaches of ethics. Whenever scientific misconduct is suspected or concerns arise about the integrity of work described in submitted or published papers, the editor initiates appropriate procedures in line with COPE guidelines. Investigations are conducted, and if scientific misconduct is confirmed, the retraction process is followed. Retracted articles are prominently labeled across all forms (abstract, full text, PDF), but they remain accessible to the public. The validity of previous work by authors involved in fraudulent papers cannot be assumed.

Citation Manipulation

Manuscripts found to include citations primarily aimed at artificially increasing the number of citations to a specific author's work or articles published in a particular journal will incur penalties for citation manipulation.

Improper Author Contribution or Attribution

We expect the corresponding author to accurately list the names of all authors and contributors in the manuscript. Prior to acceptance and during the final copy-proof stage, the manuscript should be circulated among all co-authors for their review and input. This ensures that all contributors are appropriately acknowledged, and the authorship sequence is verified to avoid errors.

Redundant Publications

CATHALOGUE closely monitors studies and their outcomes and discourages redundant publications. Dividing study outcomes into multiple smaller papers solely to increase publication count is discouraged. However, if the data is extensive and several parameters are involved, making it impossible to summarize in a single paper, such division may be justifiable. Nevertheless, the demographics of the study must not be plagiarized, and the results cannot be published separately.


For any proven misconduct, CATHALOGUE promptly notifies the author's institution, and the respective article is immediately retracted (though it remains available in the public domain).


Correction, Retraction, and

Editorial Expressions of Concern

Disagreements and complaints related to manuscripts submitted to CATHALOGUE should be addressed to the relevant editors. The journal follows the following policies for corrections in the online version of the manuscript. Valid evidence must be provided to support amendments that affect the publication record and accuracy of the published article. Corrections should be succinctly explained and notified via email (also refer to ICMJE guidelines).

Categories of Amendments:

  • Publisher Correction:

Complaints regarding journal errors that affect the manuscript's integrity and the author's reputation are considered by the editorial team.

  • Author Correction:

Authors are encouraged to report errors post-publication. Corrections for minor issues that do not impact the scientific accuracy of the article, such as typographical errors, should be avoided. Corrections related to the main scientific content, methodologies, results, and conclusions that affect the integrity of the scientific findings will be considered. These corrections will not be published as separate articles but will be linked as notices to the original article's webpage.

  • Retraction:

If previously published articles are found to contain invalid results, a retraction statement indicating the invalidity of the article is published and linked to the original paper. The original article remains accessible to readers but is clearly marked as retracted on the website.

  • Editor's Statement:

Editors may provide statements to highlight issues with published manuscripts. These statements are displayed alongside the published manuscript to inform readers about the complications.
