Manuscripts must be submitted by one of the authors of the manuscript, and should not be submitted by anyone on their behalf. The principal/corresponding author will be required to submit a Copyright Letter along with the manuscript, on behalf of all the co-authors (if any). The author(s) will confirm that the manuscript (or any part of it) has not been published previously or is not under consideration for publication elsewhere. Furthermore, any illustration, structure or table that has been published elsewhere must be reported, and copyright permission for reproduction must be obtained.
For all online submissions, please provide soft copies of all the materials (main text in MS Word or Tex/LaTeX), figures / illustrations in TIFF, PDF or JPEG, and chemical structures drawn in ChemDraw (CDX)/ISISDraw (TGF) as separate files, while a PDF version of the entire manuscript must also be included, embedded with all the figures / illustrations / tables / chemical structures etc. It is advisable that the document files related to a manuscript submission should always have the name of the corresponding author as part of the file name, i.e., “Cilli MS text.doc”, “Cilli MS Figure 1”, etc.
It is imperative that before submission, authors should carefully proofread the files for special characters, mathematical symbols, Greek letters, equations, tables, references and images, to ensure that they appear in proper format.
References, figures, tables, chemical structures etc. should be referred to in the text at the appropriate place where they have been first discussed. Figure legends/captions should also be provided.
A successful electronic submission of a manuscript will be followed by a system-generated acknowledgement to the principal/corresponding author. Any queries therein should be addressed to email@example.com

It is advisable that authors prepare their manuscript using the template available on the Web, which will assist in preparation of the manuscript according to Journal’s Format. Download the Template.
Manuscripts submitted for research and review articles in the journal should be divided into the following sections
List of Abbreviations (if any)
Consent for Publication
Availability of Data and Materials
Conflict of Interest
Figures/Illustrations (if any)
Chemical Structures (if any)
Tables (if any)
Supportive/Supplementary Material (if any)
The title of the article should be precise and brief and must not be more than 120 characters. Authors should avoid the use of non-standard abbreviations and question marks in titles. The first letter of each word should be in capital letters except for articles, conjunctions and prepositions.
As recommended by the Reporting guidelines information about the study should be a part of the title (particularly for systematic reviews and meta analyses).
Authors should also provide a short ‘running title’. Title, running title, byline, correspondent footnote and keywords should be written as presented in original manuscripts.
Title page should include paper title, author(s) full name and affiliation, corresponding author(s) names complete affiliation/address, along with phone, fax and email.
The abstract of an article should be its clear, concise and accurate summary, having no more than 250 words, and including the explicit sub-headings (as in-line or run-in headings in bold). Use of abbreviations should be avoided and the references should not be cited in the abstract.
Ideally, each abstract should include the following sub-headings, but these may vary according to requirements of the article.
The headings can vary, but must state the purpose of the study, details of the participants, measurements, methods, main findings and conclusion.
A graphic should be included when possible with each manuscript for use in the Table of Contents (TOC). This must be submitted separately as an electronic file (preferred file types are EPS, PDF, TIFF, Microsoft Word, PowerPoint and CDX etc.). A graphical abstract, not exceeding 30 words along with the illustration, helps to summarize the contents of the manuscript in a concise pictorial form. It is meant as an aid for the rapid viewing of the journals' contents and to help capture the readers’ attention. The graphical abstract may feature a key structure, reaction, equation, etc. that the manuscript elucidates upon. It will be listed along with the manuscript title, authors’ names and affiliations in the contents page, typeset within an area of 5 cm by 17 cm, but it will not appear in the article PDF file or in print.
Graphical Abstracts should be submitted as a separate file (must clearly mention graphical abstract within the file) online via Bentham's Manuscript Processing System (MPS).
You can view a few examples of the Graphical Abstracts on our website.
6 to 8 keywords must be provided. Choose important and relevant keywords that researchers in your field will be searching for so that your paper will appear in a database search. The keywords should be contained in the title and they should appear several times in the article.
The main text should begin on a separate page and should be divided into title page, abstract and the main text. The text may be subdivided further according to the areas to be discussed, which should be followed by the List of Abbreviations, Conflict of Interest, Acknowledgements and Reference section. For Review, the manuscript should be divided into title page, abstract and the main text. The text may be subdivided further according to the areas to be discussed, which should be followed by the Acknowledgements and Reference section. The review article should mention any previous important reviews in the field and contain a comprehensive discussion starting with the general background of the field. It should then go on to discuss the salient features of recent developments. The authors should avoid presenting material which has already been published in a previous review. The authors are advised to present and discuss their observations in brief.
The manuscript style must be uniform throughout the text and 10 pt Times New Roman font should
be used. The full term for an abbreviation should precede its first appearance in the text
unless it is a standard unit of measurement. The reference numbers
should be given in square brackets in the text. Italics should be used for Binomial names of
organisms (Genus and Species), for emphasis and for unfamiliar words or phrases. Non-assimilated
words from Latin or other languages should
also be italicized e.g
Section headings should be numbered sequentially, left aligned and have the first letter
capitalized, starting with the introduction. Sub-section headings however, should be in
lower-case and italicized with their initials capitalized. They should be
numbered as 1.1, 1.2,
The Introduction section should include the background and aims of the research in a comprehensive manner.
This section provides details of the methodology used along with information on any previous efforts with corresponding references. Any details for further modifications and research should be included. Sufficient details should be provided to the reader about the original data source in order to enable the analysis, appropriateness and verification of the results reported in the study.
It is important for the Methods Section should be sufficiently detailed in respect of the data presented, and the results produced from it. This section should include all the information and protocol gathered for the study at the time when it was being written. If the study is funded or financially supported by an organization to conduct the research, then it should be mentioned in the Methods Section. Methods must be result-oriented.
Repeated information should not be reported in the text of an article. A calculation section must include experimental data, facts and practical development from a theoretical perspective.
The important and main findings of the study should come first in the Results Section. The tables, figures and references should be given in sequence to emphasize the important information or observations related to the research. The repetition of data in tables and figures should be avoided. Results should be precise.
This should explore the significance of the results of the work, present a reproducible procedure and emphasis the importance of the article in the light of recent developments in the field. Extensive citations and discussion of published literature should be avoided.
The Results and Discussion may be presented together under one heading of “Results and Discussion”. Alternatively, they may be presented under two separate sections (“Results” Section and “Discussion” Sections). Short sub- headings may be added in each section if required.
A small paragraph summarizing the contents of the article, presenting the final outcome of the research or proposing further study on the subject, may be given at the end of the article under the Conclusion section.
The authors need to declare the funding sources of their manuscripts clearly by providing the name of the funding agency or financial support along with allotted grant/award number in round brackets (if applied), for instance, “This work was financially supported by [Name of the funding agency] (Grant number XXX).
Similarly, if a paper does not have any specific funding source, and is part of the employment of the authors, then the name of the employer will be required. Authors will have to clearly state that the funder was involved in writing, editing, approval, or decision to publish the article.
Greek symbols and special characters often undergo formatting changes and get corrupted or lost during preparation of manuscript for publication. To ensure that all special characters used are embedded in the text, these special characters should be inserted as a symbol but should not be a result of any format styling (Symbol font face) otherwise they will be lost during conversion to PDF/XML.
Authors are encouraged to consult reporting guidelines. These guidelines provide a set of recommendations comprising a list of items relevant to their specific research design. Chemical equations, chemical names, mathematical usage, unit of measurements, chemical and physical quantity & units must conform to SI and Chemical Abstracts or IUPAC.
All kinds of measurements should be reported only in International System of Units (SI).
In case there is a need to present lengthy, but essential methodological details, appendices must be used, which can be a part of the article. An appendix must not exceed three pages (Times New Roman, 10 point fonts, 900 max. words per page).The information should be provided in a condensed form, ruling out the need of full sentences. A single appendix should be titled APPENDIX, while more than one can be titled APPENDIX A, APPENDIX B, and so on.
We do encourage to append supportive material, for example a PowerPoint file containing a talk about the study, a PowerPoint file containing additional screenshots, a Word, RTF, or PDF document showing the original instrument(s) used, a video, or the original data (SAS/SPSS files, Excel files, Access Db files etc.) provided it is inevitable or endorsed by the journal's Editor.
Supportive/Supplementary material intended for publication must be numbered and referred to in the manuscript but should not be a part of the submitted paper. In-text citations as well as a section with the heading "Supportive/Supplementary Material" before the "References" section should be provided. Here, list all Supportive/Supplementary Material and include a brief caption line for each file describing its contents.
Any additional files will be linked to the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided only on our Web site. Please also make sure that each additional file is a single table, figure or movie (please do not upload linked worksheets or PDF files larger than one sheet). Supportive/ Supplementary material must be provided in a single zipped file not larger than 4 MB.
Authors must clearly indicate if these files are not for publication but meant for the reviewers'/editors' perusal only.
If abbreviations are used in the text either they should be defined in the text where first used, or a list of abbreviations can be provided.
All potential conflicts of interest (competing interests) that could have a direct or indirect influence on the work must be disclosed by the authors. Even if an author does not have a conflict, disclosing affiliations and interests allows for a more comprehensive and open approach, which leads to a more accurate and objective evaluation of the work. Conflicts of interest, whether genuine or imagined, are a perspective to which the readers are entitled.
The publication of a conflict statement in the article itself, as well as the submission of the conflict disclosure form, is required for all types of papers. It is not necessarily the case that a monetary relationship with examination support or funding for counseling work is inappropriate. Even if the authors do not have any conflict of interest, they still need to provide a confirmation statement in their manuscripts, i.e., “The author(s) confirm(s) that there is no conflict of interest related to the manuscript.”
The following are some examples of potential conflicts of interest that are directly or indirectly related to the research:
Type of support/grant number
Institutional Conflicts of Interest
Funds received by the author
Funds received by the institution
Travel allowances for the research
Funds received for article preparation and reviewing
Funds for conducting review activities
Support provided for article writing assistance, for drugs, equipment, etc
Pending fund or grant
Financial conflicts of interest can be personal as well as institutional. Personal conflict of interest occurs when a contributor involved in the publication process either receives an amount of money or expects to receive some financial help (including any other financial benefits such as patents or stocks, gifts or services) that may impact the work related to a specific publication. More importantly, in academic research, such financial relationships can lead to institutional conflicts of interest (COIs) because the economic interests of the institution or institutional representatives may unsuitably affect the decision-making process.
An institutional conflict of interest arises in a situation when financial interests of an institution or any institutional official (e.g., investments held by the university in a company) have the potential to unduly influence the research conducted by its employees or students, or pose an unacceptable risk to human subjects. Such conflicts usually arise in a state of affairs where a research project directly offers assistance or a benefit to an external entity via evaluation, validation, trial or test of an invention, product, drug, service or technology, and the institution holds a financial interest with the external entity. Such financial interests incorporate, but are not limited to, receipt of licensing payments or royalties from the external entity, or ownership interest with the external entity. When human subjects are involved in any research project, and the institution supports such a financial interest, the conflict of interest is speculated to be unreasonable.
In addition, interests other than monetary and any funding (non-financial interests) should be declared if they are relevant to readers. Personal relationships or conflicting interests directly or indirectly related to research, as well as professional interests or personal opinions that may impact your research, are examples of these.
Intellectual property, in basic terms, refers to any intangible property that is the result of creativity, such as patents, copyrights, etc. Similarly, this section seeks to know about copyright and patent (licensed patent, pending or issued) and any payment received for intellectual property, such as:
All conflict of interest disclosure forms are collected by the corresponding author. It is sufficient for the corresponding author to sign the disclosure form on behalf of all authors in author collaborations when legal agreements for representation allow it. The templates of the form can be found here.
Before the reference list, the corresponding author will include a summary statement in the text of the article that reflects what is reported in the potential conflict of interest disclosure form (s). Author(s) may declare(s) names of reviewers who they think might have a potential conflict of interest; therefore, Editorial Office could avoid inviting such reviewers for an unbiased opinion.
Undisclosed conflict of interest cases before or after the publication of an article are dealt with as per the guidelines of COPE.
Undisclosed conflict of interest in a submitted article (View COPE guidelines)
Undisclosed conflict of interest in a published article (View COPE guidelines)
For more information on COIs, see the guidance from the ICMJE.
Bentham Science tries to conduct a transparent peer-review process with the help of the reviewers who do not have any conflict of interest with the authors. In this connection, reviewers who belong to the same institute or countries as authors are not invited to review manuscripts. However, it is not possible for the Editorial Office to be aware of all competing interests; therefore, it is expected from authors to submit:
List of reviewers who they think have a conflict of interest to ensure a transparent and unbiased review process.
The Editorial Office expects reviewers:
Not to accept manuscript review requests if they have any potential conflict of interest and inform the Editorial Office accordingly.
To decline review requests if they have recently published or submitted an article with any of the authors listed in the manuscript.
To inform the Editorial Office if they have any personal relationship with the authors or work in the same institutes as of authors, which could affect the review transparency.
To abstain from reviewing and informing the Editorial Office/Editor-in-Chief/Handling Editors about any scientific misconduct or fraud, plagiarism, conflict of interest, or any other unethical behavior related to the manuscript, which they found while reviewing it.
During the submission of review comments, reviewers are asked to reconfirm that they do not have any conflict of interest related to the article. After confirming the below statement, they can submit their comments.
“I hereby confirm that I don’t have any conflict of interest related to the manuscript.”
If, however, there are still any remaining interests, then reviewers must mention those in the ‘Confidential’ section of the review form.
Reviewers are not encouraged to contact authors directly regarding any of their conflicts of interest. Peer reviewers should follow journals’ policies in situations they consider to represent a conflict to reviewing.
If reviewers intentionally undisclosed any conflict of interest, then they will be blacklisted for any future peer reviewing activity of the journal.
The Editorial Office always ensures that an author, if added after peer review activity of a manuscript, is not part of the reviewers’ list who have conducted a peer review of the same manuscript.
Editors must not review submitted manuscripts if they have any personal, professional or financial involvement/conflict of interest with the authors of the manuscript. Every participant involved in the peer review process, including editorial board members, reviewers, and editors, must declare any potential conflicts of interest to ensure a transparent and unbiased review activity.
Editors-in-Chief or Editors who are responsible for the initial and final decision should recuse themselves to review or take decisions on any manuscript that is written by authors affiliated to the same institute as of editor, or if they have been a family member, competitor, collaborator, or have published any manuscript in last 3 years with the authors associated with the manuscript. They can however nominate someone else on the Board who could provide a neutral opinion on the manuscript.
The initial and final decision on the manuscripts submitted by an Editor/Editor-in-Chief will be taken by any other member of the Board. The Editorial Office will identify members who do not have any potential conflict of interest with the Editor or Editor-in-Chief.
All individuals listed as authors must have contributed substantially to the design, performance, analysis, or reporting of the work and are required to indicate their specific contribution. Anyone (individual/company/institution) who has substantially contributed to the study for important intellectual content, or who was involved in the article’s drafting the manuscript or revising must also be acknowledged.
Guest or honorary authorship based solely on position (e.g. research supervisor, departmental head) is discouraged.
If the manuscript has an individuals’ data, such as personal detail, audio-video material etc., consent should be obtained from that individual.
All such case reports should be followed by a proper consent prior to publishing.
Post-publication discussions are well-timed and engaging scientific remarks and justifications on research articles published in "Current Medicinal Chemistry". These remarks must be based on the information concurrent with the original study and not on the scientific advancements being made subsequently.
Manuscript Preparation, Submission & Editorial Process:
- Post-publication discussion should commence with a short paragraph that outlines the summary of the article.
- Authors are advised to avoid using inciting tone in the comments and keep the message clear and concise.
- The main text should not exceed 1200 words with up to 15 references and may include one or two figures and/or tables.
- References should be submitted in the ACS or Vancouver style.
- The correspondents are recommended to contact the original authors first prior to submitting their comments to the journal as this may resolve the issues that may have arisen due to some misunderstanding.
- The correspondence that has been done with the authors should also be submitted as an attachment with the manuscript.
Any queries therein should be addressed to firstname.lastname@example.org
The NIH acknowledges the misidentification and/or cross-contamination of cell cultures e.g. HeLa cells being used in a research study as a serious problem. In order to ensure the validation of the work and proper utilization of resources, it is a prerequisite that correct reagents be used in studies dealing with established human (tumor) cell lines that have been cultured for more than 4 years up to the date of submission of the manuscript. Cell lines such as short-term cultures of human tumors, murine cell lines (as a catalog of DNA profiles is not yet available) and tumor cell lines established in the course of the study that is being submitted, are presently exempt from this rule. To minimize the risk of working with misidentified and/or contaminated cell lines, tests such as isoenzyme analysis, karyotyping/cytogenetic analysis and, more recently, molecular techniques of DNA profiling may be carried out to authenticate cell cultures. These tests may help confirm or establish the identify profile for a cell line. Bentham Science recommends that all cell lines be authenticated prior to submitting a paper for review. Authors are therefore required to provide authentication of the origin and identity of the cells by performing cell profiling either in their own laboratory or by outsourcing an approved laboratory or cell bank. Authentication is required when a new line is established or acquired, before freezing a cell line, if the performance of the line is not consistent or results are unexpected, if using more than one cell line, and before publication of the study.
The cell lines profile should be cross-checked with the profile of the donor tissue of other continuous
cell lines such as provided by the authentic data bank such as DSMZ (www.dsmz.de/fp/cgi-bin/str.html),
References must be listed in the ACS Style only. All references should be numbered sequentially [in square brackets] in the text and listed in the same numerical order in the reference section. The reference numbers must be finalized and the bibliography must be fully formatted before submission.
The references should be relevant to the study and should refer to the original research sources. Self-citation and self-interest should be avoided by the authors, editors and peer-reviewers.

The authors are encouraged to use a recent version of EndNote (version 5 and above) or Reference Manager (version 10) when formatting their reference list, as this allows references to be automatically extracted.
The source of data and materials should be mentioned in the manuscript, in support of the findings. Sharing research data is integral to its transparency and reproducibility. Data sharing involves the citation and availability of data that support the findings of the research.
Bentham Science encourages authors to share the source of data and materials in the manuscript, in support of the findings.
The four types of research data policies are mentioned below.
Wherever appropriate and possible, the journal encourages authors to publish data to support their research findings in a public repository. Any datasets mentioned in the article that are available in external repositories should be cited.
How to Cite the Data?
Whether the data was developed by the author(s) or researcher(s), all publicly available data referenced in the preparation of an article should be cited in the text and reference list. The references relating to the data availability should be presented in the following format:
Example: Name of author(s), the title of data set, data repository, document version (e.g., most recent updated version), Digital Object Identifier (DOI), and Bentham Science reference style should be included in data citations.
When authors submit a paper to a journal, the authors agree that the data provided in the publication, including the relevant raw data, will be freely available to any researcher who wants to use these for non-commercial reasons without jeopardising participant anonymity.
Data availability declarations are required under Bentham Science research data policy types.
The statement relating to the data availability should be presented in the following format under a separate section for ‘Availability of Data and Materials’ in the manuscript:
"The data supporting the findings of the article is available in the [repository name] at [URL], reference number [reference number]”.
Authors can add or change the statement(s) above, to fit their work the best. Depending on the nature of the research, several assertions may need to be merged.
All datasets on which the paper's conclusions are based must be made accessible to reviewers and readers, according to the journal's rules. Prior to peer review, authors must either deposit their datasets in publicly accessible repositories or provide them as supplementary materials with their submission. For further details, please visit complete guidelines at: http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html
All authors must strictly follow the guidelines below for preparing illustrations for publication in
The authors are expected to submit good quality figure(s) in PDF, PPT, MS Word, TIFF or JPEG versions, which, if required, should be improved yourself or by professional graphic designers of your organization/ country. You may even consider approaching our contracted service providers Eureka Science for Graphics Enhancement Services.
The Graphics Designing team at Eureka Science can assist in
improving the quality of your images at affordable rates. Eureka
Science has offered special rates of

Illustrations must be provided according to the following guideline:
Illustrations should be embedded in the text file, and must be numbered consecutively in the order of their appearance. Each figure should include only a single illustration which should be cropped to minimize the amount of space occupied by the illustration.
If a figure is in separate parts, all parts of the figure must be provided in a single composite illustration file.
Photographs should be provided with a scale bar if appropriate, as well as high-resolution component files.
Line Art image type is normally an image based on lines and text. It does not contain tonal or shaded areas. The preferred file format should be TIFF or EPS, with the color mode being Monochrome 1-bit or RGB, in a resolution of 900-1200 dpi.
Halftone image type is a continuous tone photograph containing no text. It should have the preferred file format TIFF, with color mode being RGB or Grayscale, in a resolution of 300 dpi.
Combination image type is an image containing halftone , text or line art elements. It should have the preferred file format TIFF, with color mode being RGB or Grayscale, in a resolution of 500-900 dpi.
Illustrations may be submitted in the following file formats:
Bentham Science does not process figures submitted in GIF format.
For TIFF or EPS figures with considerably large file size restricting the file size in online submissions is advisable. Authors may therefore convert to JPEG format before submission as this results in significantly reduced file size and upload time, while retaining acceptable quality. JPEG is a ‘lossy’ format. However, in order to maintain acceptable image quality, it is recommended that JPEG files are saved at High or Maximum quality.
Zipit or Stuffit tools should not be used to compress files prior to submission as the resulting compression through these tools is always negligible.
Please refrain from supplying:
Graphics embedded in word processor (spreadsheet, presentation) document.
Optimized files optimized for screen use (like GIF, BMP, PICT, WPG) because of the low resolution.
Files with too low a resolution.
Graphics that are disproportionately large for the content.
Technical requirements for graphic/ figure submissions.
Width = 8.5 inches (In-between the required size)
Height = 11 inches (In-between the required size)
Pixels/Inches = 300 (minimum dpi)
All figures should be in vector scale (except half tone, photograph.)
There are many software packages, many of them freeware or shareware, capable of converting to and from different graphics formats, including PNG.
General tools for image conversion include Graphic Converter on the Macintosh, Paint Shop Pro, for Windows, and ImageMagick, available on Macintosh, Windows and UNIX platforms.
Bitmap images (e.g. screenshots) should not be converted to EPS as they result in a much larger file size than the equivalent JPEG, TIFF, PNG or BMP, and poor quality. EPS should only be used for images produced by vector-drawing applications such as Adobe Illustrator or CorelDraw. Most vector-drawing applications can be saved in, or exported as, EPS format. If the images were originally prepared in an Office application, such as Word or PowerPoint, original Office files should be directly uploaded to the site, instead of being converted to JPEG or another format of low quality.
The cost for each individual page of color figures/plates/illustrations is
Color figures should be supplied in CMYK and not RGB colors.
Chemical structures MUST be prepared in ChemDraw/CDX and provided as separate file.

Tables should be embedded in the text exactly according to their appropriate placement in the submitted manuscript.
Columns and rows of data should be made visibly distinct by ensuring that the borders of each cell are displayed as black lines.
Tables should be numbered in Arabic numerals sequentially in order of their citation in the body of the text.
If a reference is cited in both the table and text, please insert a lettered footnote in the table to refer to the numbered reference in the text.
Tabular data provided as additional files can be submitted as an Excel spreadsheet.
It is adequate to present data in Tables to avoid unnecessary repetition and reduce the length of the text.

Bentham Science Publishers requires that all individuals listed as authors must have made a substantial contribution to the design, performance, analysis, or reporting of the work. The role of authors is judged on the basis of ICMJE and COPE guidelines.
All contributing authors are required to sign a copyright letter, mentioning complete details, including full name, affiliation, email address, ORCID ID and their role in the article. After successful electronic submission of a manuscript, a system-generated acknowledgement will be sent to all authors on their provided email addresses.
Authors must provide a final list of authors at the time of submission, ensuring the correct sequence of the names of authors, which will not be considered for any addition, deletion or rearrangement after final submission of the manuscript. The email address of the principal author should be provided with an asterisk. However, the complete address, business telephone numbers, fax numbers and e-mail address of the corresponding author must be stated to receive correspondence and galley proofs. Bentham Science Publishers recommends that all contributors regularly update their profiles on SCOPUS/ORCID and other databases.
Authors are strongly recommended to use their ORCID ID when submitting an article for consideration. Alternatively, they can acquire an ORCID ID via the submission process. For more information about ORCID IDs, visit here.
At the time of initial submission, the finalized list of authors in correct sequence should be provided, which will not be changed once the publication process has started.
If any change is essential, then it can only be done after the approval of the Editor-in-Chief upon receiving the following details from the corresponding author:
- The reason for the change in the author list and/or their sequence
- A proper justification should be provided for changes in authorship.
- Correction of existing names should be accompanied by a notice to the Editor-in-Chief of the journal.
Any amendment to the authors' list will only be considered and approved by the Editor-in-Chief after complete verification. Publication of the manuscript will be withheld during consideration of the request. However, if the manuscript has already been published online, requests approved thereafter by the Editor-in-Chief will result in an erratum or corrigendum. The corresponding author is responsible for obtaining permission from all co-authors for any changes in the authorship.
Here is some advice by COPE on authorship issues. Bentham strives to follow these guidelines.
Activities such as the acquisition of funding, general supervision of a research group or general administrative support, writing assistance, technical editing, language editing, and proofreading alone do not qualify any contributor for authorship. Such contributors may be acknowledged individually or together as a group in the acknowledgement section. Further details for writing acknowledgements are available here. Persons not meeting authorship criteria can be acknowledged in the acknowledgement section of the article rather than being enlisted as authors.
All contributing authors should contribute substantially to the article and sign the copyright letter. Bentham Science Publishers discourages authorship based solely on position (e.g., a research supervisor or a departmental head). We use COPE guidelines for identifying any suspected ghost, guest or gift authorship.
Manuscripts containing language inconsistencies will not be published. Authors should seek professional assistance for correction of grammatical, scientific and typographical errors before submission of the revised version of the article for publication. Professional editing services may also be sought by the team available at Bentham Science.
Authors will receive page proofs of their accepted paper before publications. To avoid delays in
publication, proofs should be checked immediately for typographical errors and returned within
The corresponding author will be solely responsible for ensuring that the revised version of the manuscript incorporating all the submitted corrections receives the approval of all the co-authors of the manuscript.
No page charges will be levied for the publication of Review Articles. However, publication charges (inclusive of limited time free to view option ) of US$ 1450 per article are payable for Research Articles.
Bentham Science offers a 50% discount off all page charges for manuscripts of all corresponding authors who reside in countries which are categorized as low-income economies by the World Bank. To see if you qualify to the discount, please refer to the complete list of these countries click here
Publication fees (Article Processing Charges) only become due after an article has been both reviewed and accepted for publication. Therefore, submission of an article is not a guarantee that it will be published. The final decision on the manuscript is made by the Editor-in-Chief on the basis of at least two independent peer-review reports.
Other service fees for activities such as Quick Track Services, Open Access Plus, Animated Abstracts, Color Figure, Figure Improvement or Language Editing are optional and are only charged as and when these services are availed.
For this journal an optional fast publication fee-based service called QUICK TRACK is available to authors for their submitted manuscripts. Authors who opt for this fee-based service do not have to pay any additional page charges.
QUICK TRACK allows online publication within 2 weeks of receipt of the final approved galley proofs from the authors. Similarly the manuscript can be published in the next forthcoming PRINT issue of the journal. The total publication time, from date of first receipt of manuscript to its online publication is 10 weeks, subject to its acceptance by the referees and modification (if any) by the authors within one week.
The author will be initially charged a small fee on receipt of the agreement form for Quick Track publication to partially cover the initial costs incurred for expedited processing of the submitted manuscript. Later, the full Quick Track publication fee (US$ 3950 per article charge) will be payable before online publication of the article. However, if the article is rejected at the peer-review stage, then the US$ 3950 per article charge will not apply.
Please note that whether the author opts for the QUICK TRACK facility or not, standard reviewing practices will be followed, which will not in any way affect the acceptance or rejection of the manuscript by the reviewers.
Authors who have availed QUICK TRACK service in a BSP journal will be entitled for an exclusive

All papers submitted for publication are immediately subjected to preliminary editorial scrutiny by the Editor-in-Chief regarding their suitability. The Editor-in-Chief determines if the manuscript
(a) falls within the scope of the journal and
(b) meets the editorial criteria of
Manuscripts that appear to be suitable are then subjected to single peer-review by, usually three, neutral eminent experts. The services of eminent international experts are sought through invitations to conduct the peer-review of a submitted manuscript, keeping in view the scope of the manuscript and the expertise of the reviewers. The identity of the reviewers is not disclosed to the authors. The anonymity of reviewers ensures objective and unbiased assessment of the manuscript by the reviewers.
Before sending the manuscripts to reviewers,
The editorial process and peer-review workflow for each journal are taken care of by a team of Senior Editors, Editorial Board Members (EBMs) and dedicated Journal managers who have the required expertise in their specific fields.
Bentham Science Publishers carries out independent review of all articles. The reviewers are selected according to their expertise, from our, regularly updated, referee database.
On the basis of reviewer comments, the Editors may recommend acceptance, revision or rejection of a manuscript.
After review of the manuscript by at least three independent experts, in addition to the views of the Editor, the decision is relayed to the authors, which may be categorized as:
Requires minor changes
Requires major changes
Rejected but may be resubmitted
Rejected with no resubmission
The authors are usually requested to resubmit the revised paper within 15 days and it will then be returned to the reviewers for further evaluation. The publishers normally allow one round of revision and, in exceptional cases, a second round of revision may be allowed. If further revision is needed, then the manuscript is rejected and the author is requested to resubmit the manuscript for fresh processing.
The final decision regarding acceptance or rejection is that of the Editor-in-Chief, depending on the quality of the revision and his assessment of the quality of the manuscript. In rare cases, manuscripts recommended for publication by the referees may be rejected in the final assessment by the Editor-in-Chief.
The time frame for revision of any article may vary from one to four weeks, depending on the nature of the revision required (minor or major). However, authors who need extra time for revision should consult the Editor-in-Chief/Handling Editor with valid reasons and the submission date of the revised manuscript may be extended if the request is genuine.
After the successful completion of the review and acceptance of the article, the articles are typeset and proofs are dispatched to authors for any corrections prior to final publication.
Bentham Science Publishers strictly follows the COPE guidelines to detect plagiarism; for more clear insight, authors may refer to flowcharts provided by COPE by clicking here or by visiting COPE website.
The text of every submitted manuscript is checked by using the Content Tracking mode in iThenticate. The Content Tracking mode ensures that manuscripts with an overall low percentage similarity (but which may have a higher similarity from a single source) are not overlooked. If the similarity level is significantly high, then the manuscript is returned to the author for paraphrasing the text and citing the original source of the copied material.
It is important to mention that the text taken from different sources with an overall low similarity percentage will be considered as a plagiarized content if the majority of the article is a combination of copied material.
There may be some manuscripts with an overall low similarity percentage, but a higher percentage from a single source. For instance, a manuscript may have less than 20% overall similarity but there may be 15 % similar text taken from a single article; the similarity index in such cases is higher than the approved limit for a single source. Authors are advised to thoroughly rephrase the similar text and properly cite the original source to avoid plagiarism and copyright violation.
We all know that scholarly manuscripts are written after a thorough review of previously published articles. It is therefore, not easy to draw a clear boundary between legitimate representation and plagiarism. However, the following important features can assist in identifying different kinds of plagiarized content. These are:
Reproduction of others words, sentences, ideas or findings as one’s own without proper acknowledgement.
Text recycling, also known as self-plagiarism. It is an author’s use of a previous publication in another paper without proper citation and acknowledgment of the original source.
Paraphrasing poorly: Copying complete paragraphs and modifying a few words without changing the structure of original sentences or changing the sentence structure but not the words.
Verbatim copying of text without putting quotation marks and not acknowledging the work of the original author.
Properly citing a work but poorly paraphrasing the original text is considered as unintentional plagiarism. Similarly, manuscripts with language somewhere between paraphrasing and quoting are not acceptable. Authors should either paraphrase properly or quote and in both cases, cite the original source.
Higher similarity in the abstract, introduction, materials and methods, and discussion and conclusion sections indicates that the manuscript may contain plagiarized text. Authors can easily explain these parts of the manuscript in many ways. However, technical terms and sometimes standard procedures cannot be rephrased; therefore Editors must review these sections carefully before making a decision.
Published manuscripts which are found to contain plagiarized text are retracted from the journal website after careful investigation and approval by the Editor-in-Chief of the journal. A ‘Retraction Note’ as well as a link to the original article is published on the electronic version of the plagiarized manuscript and an addendum with retraction notification in the journal concerned.
