Just published: A masterful work on medical pharmacology

21 April 2026

Health Sciences and Disease is pleased to announce the publication of the book: "Medical Pharmacology: Its Birth, Fundamentals, Current Outlines, and Future" by Pr E Eben-Moussi.

In this comprehensive essay, Professor Eben Moussi Emmanuel, an international expert and former senior WHO official, delivers a profound reflection on medicine. Beyond the core fundamentals, the author analyzes medicine as a unique industrial commodity and explores the critical challenges of R&D in the face of tomorrow's societal shifts.

EDITORIAL POLICIES
Ethics
HSD’s Policy Committee follows the recommendations of the International Committee of Medical Journal Editors (ICMJE), the World Association of Medical Editors (WAME), and the Committee on Publication Ethics (COPE) for guidance on policies and procedures related to publication ethics. The policies for HRA have been adapted from those three advisory bodies and, where necessary, modified and tailored to meet the specific content, audiences, and aims of HSD.
Peer review process
Research manuscripts are initially checked by the editor in chief or section editor for identification of gross deficiencies. At this stage, the proposal may be rejected. After this initial screening, articles are sent to one or two-reviewers whose names are hidden from the author and whose review is guided by a checklist (single anonymized review). The review summary is signed by the reviewer and is not posted with article. The review process may take days to weeks to reach a final decision that is the responsibility of the editor in chief. The duration from submission to publication may take one to six months (average: 6 months). So, the authors should avoid contacting the editorial office less than 6 weeks after the initial submission.
Plagiarism, scientific misconduct
Manuscripts are randomly checked for plagiarism with available free tools. Those proven of plagiarism are returned to the authors without peer review. The editors reserve the right to request that the authors provide additional data collected during their investigations. The editors also reserve the right to send a copy of the manuscript and data in question to the author’s dean, university, or supervisor or, in the case of an investigation being funded by an agency, to that funding agency for appreciation.
Conflict of interest
At the time of submission, authors are asked to disclose whether they have any financial interests or connections, direct or indirect, or other situations that may influence directly or indirectly the work submitted for consideration.
Human and animal studies
Manuscripts reporting results of prospective or retrospective studies involving human subjects must document that appropriate institutional review board (IRB) approval and informed consent were obtained (or waived by the IRB) after the nature of the procedure(s) had been fully explained. In any case, medical research involving human subjects should comply with the Declaration of Helsinki (2013).
Authorship
To be listed as an author, an individual must have made substantial contributions to all three categories established by the ICMJE (http://www.icmje.org): (a) “conception and design, or acquisition of data, or analysis and interpretation of data,” (b) “drafting the article or revising it critically for important intellectual content,” and (c) “final approval of the version to be published.” Individuals who have not made substantial contributions in all three categories but who have made substantial contributions either to some of them or in other areas should be listed in acknowledgments.
Please limit the number of authors to ten when this is feasible.
Content licensing - Open access compliance
Since 2013 , articles published in HSD are Open Access and distributed under the terms of the Creative Commons Attribution 4.0 International (CC BY 4.0), which means that all content is freely available without charge to the user or his/her institution. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the publisher, provided the original work is properly cited.
Artificial Intelligence (AI)–Assisted Technology
At submission, the authors should disclose whether they used artiﬁcial intelligence (AI)–assisted technologies in the production of the publication and how AI was used. However, authors should not list AI and AI-assisted technologies as an author or co-author, nor cite AI as an author.
ARTICLE PROCESSING CHARGES (APC)
Article submission is free of charges, but if your paper is accepted for publication, you will be asked to pay article processing charges to cover publications costs, depending on the type, complexity and length of the work, and on the number of authors
FAST TRACK
Inquiries about fast track, manuscript status and preparation, as well as letters to the editor, should be directed to:
