Submissions

Author Guidelines

Submission and Evaluation

When filling out the registration of authors in the journal system and submitting a manuscript, a confirmation email is sent to the corresponding Author. The editorial review process only starts if the manuscript follows the established norms (Submissions and Manuscript preparation (Template)); otherwise, it is returned for adequacy.

Manuscripts that comply with the prescribed standards will be submitted to similarity detection software and analyzed by the Editorial Committee, which will decide whether or not to proceed with the editorial analysis.

Editorial committees decision to accept or reject a submission paper will be based only on the paper’s importance, originality, and clarity, and the study’s relevance to the remit of the journal.

Papers not suitable for the journal scope will be returned to the Authors, even before the technical-scientific analysis. Manuscripts with problems regarding the textual composition structure will be returned and, if corrected, can be resubmitted.

The submitted manuscript will not be retained or copied. Editors will treat all submitted papers as confidential.

Initially approved by the Editorial Committee, the manuscripts will proceed to the next phase where the evaluators will be chosen by this same Committee, among researchers of recognized competence in the specific area of each work and, preferably, linked to different institutions from those where the manuscript under analysis was originated.

Considering that Judgments must be objective, reviewers must not present any bias and no conflict of interest.

The Editorial Committee asks the reviewers, before starting the analysis of a manuscript, to consider the possibility of some situations and/or relationships that may compromise the impartiality of the evaluation process, such as regular collaboration with possible authors in activities of research, advisor-student association, commercial interest in the publication, family relationship. In these cases, the reviewer is asked to immediately return the manuscript, communicating the impossibility of analyzing it.

Editorial Policy

The Brazilian Journal of Science is publications in continuous flow (with early access for accepted articles) that edits and publishes original technical-scientific works, in English, resulting from scientific research. The main form of contribution is the Article, but it also publishes Scientific Notes and Reviews.

Reviewer Suggestions

Authors should provide a list of 4 potential reviewers (full name, e-mail and affiliation) who are knowledgeable in the subject matter, have no conflict of interest, and are likely to agree to review the manuscript. This will significantly help facilitate timely peer review. Please ensure that 3 of the potential reviewers are from a different country to the authors and are not editors on the journal.

Attention: Editors are not able to review papers. Please also ensure that you include full contact details for each suggested reviewer - the institution, country and correct, up-to-date email addresses.

Graphical Abstract

From volume 3, Issue 1-12 in 2024 will have Graphical abstract.

A graphic should be included when possible. 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 Brazilian Journal of Science 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 using a regular screen resolution of 96 dpi, but it will not appear in the article's PDF file or print. Graphical Abstracts should be submitted as a separate file (must clearly mention graphical abstract within the file). It must not be an image already used in the manuscript. Photos of commercial equipment will not be accepted in the Graphic Abstract. We suggest the following software for Graphical Abstract, BioRender or others.

Authors’ Contributions

For transparency, BJS requires corresponding authors to provide co-author contributions to the manuscript, described in Topic Authors’ Contributions (Template in English). The following collaboration functions should be considered (adapted from the 14 functions of the CRediT classification): 1) Conceptualization: is the contribution responsible for the ideas, formulation and evolution of the objectives to be achieved in the research or article; 2) Acquisition of funding: is the contribution that refers to activities related to the acquisition of financial support for the research in question; 3) Methodology: is the contribution related to conducting the development of scientific methodology applied in research, as well as in the creation of models; 4) Investigation or data collection: it is conducting the research and investigation process (carrying out experiments, collecting data and evidence); 5) Statistical analysis: collaboration in the application of data analysis techniques and methods (statistics, mathematical, computational, spatial models, graphing, among others); 6) Administration or supervision: it is the function that is responsible for the management and coordination of the planning and execution of the research (in addition to the human resources directly involved); 7) Validation: is the collaboration related to the verification of the quality and replication/reproduction potential of the research results (and,
consequently, of the applied methods and tools); 8) Writing (original draft): is the collaboration of writing the original draft of the article, in addition to preparing the presentation of the work; 9) Writing (revision and editing): is the contribution responsible for the critical review of the work, before and after publication, in addition to preparing the presentation of the work for the original research group; 10) Translation: only when performed by the authors (in the case of companies, it should not be cited).

Changes to Authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editors.

To request such a change, the Editor-in-Chief must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.

Only in exceptional circumstances will the Editor-in-Chief and Associate Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editorin-Chief and Associate Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editors will result in a corrigendum.

Main Text

Manuscript content should adhere to the criteria for the manuscript type selected. Manuscripts must be written in English by competent, grammatically correct and scientific persons; the absence of these qualities inhibits and undermines the effectiveness of the peer review process, causing substantial delays in this step.

An informal tone and overuse of first-person pronouns, especially used as adjectives or possessives (e.g., “my”, “mine”, “our”, “ours”) and second-person pronouns (e.g., “you”, “your”) should be avoided!

Acronyms/Abbreviations/Initialisms

Should be defined the first time they appear in each of three sections: the abstract; the main text; the first Figure or Table. When defined for the first time, the acronym/abbreviation/initialism should be added in parentheses after the written-out form.

Common and Scientific Names

Attention: Both common and scientific names vary in time and space. To maximize the ability of readers to identify study organisms across the world and over time but allow authors maximum flexibility in choosing their preferred authorities:

(1) If taxonomy has changed within the last 10 years, the former name of the organism may be presented at the first use of the name [example: Eupatorium polystachyum DC. (= Raulinoreitzia crenulata (Spreng.) R.M. King & H. Rob.)]. If your preferred taxonomic hypothesis differs from that of other authors, make sure to include the more commonly used name.

(2) Species occurring out of Brazil: standard English and Spanish names should be provided at first occurrence. Standard names of all animals must be capitalized and used in the plural (e.g., Pepper Frogs). For North American species (example) use the pattern available in the North American Species Name Database (SSAR). For species in other parts of the world, common names are optional-follow an appropriate regional reference if available (e.g., Rãs Pimenta or Rã Pimenta in Portuguese (Brazil) and Chandala or Chandalas in Portuguese (Angola)).

Numbers

Always spell out a number used at the beginning of a sentence (Example: Thirty species…). Spell out all whole numbers less than 10, except as noted below.

-Use Arabic numerals:

• For numbers of 10 or greater
• When the number is followed by a unit of measurement. Example: “7 mm”
• When the number is a designator. Example: “Experiment 5”
• When a range of values is given. Example: “3–6 scutes”
• When numbers of 10 or more are compared to numbers less than 10 within a sentence. Example: “The 5 fruits, 7 reptiles, and 15 snakes that we collected…”
• Decimal values; if decimal value is < 1, use zero before decimal. Example: “0.4 or 0.7”

-Use commas in numbers with four or more digits. Example: “155” and “1,321”.

-Avoid excessive significant digits. Example: when measuring length with a ruler where the smallest measurement unit is 1 mm, report mean values as “10.55 mm” and standard deviation as “0.66 mm”.

-Numbers or letters in a list should be fully enclosed in parentheses. Example: Experiments (5), (6), and (3) failed; (2) did not.

-Geographic coordinates can be in any standard format, such as decimal degrees or UTM.

Nomenclature and SI Units (International System of Units)

Should be used. Imperial, US customary and other units should be converted to SI Units (NIST) (https://www.nist.gov/pml/owm/metric-si/si-units) whenever possible. Abbreviations used in tables and figures should be explained in the captions. In general, the recommendations of the International Union of Pure and Applied Chemistry (IUPAC) should be followed (http://www.iupac.org).

Exemples:

-Linear measurement: Millimeters = mm, Centimeters = cm, Meters = m, Kilometers = km

-Area: hectare = ha

-Volume: Milliliters = mL, Liters = L

-Mass: Grams = g, Kilograms = kg

-Use the negative index (m^-1, L^-1, h^-1) except in cases such as (per plant).

-Time: Seconds = s, Minutes = min, Hours = h, Days = d, Week = wk, Month = mo, Years = yr. For time of day, use 24-hour clock. Example: 1500 h.

-Date: use Month Day, Year with no commas, spelling out the name of the month. Example: “June 10, 2023”.

-Temperature: Celsius, with space after number and with a degree symbol before the abbreviation for temperature scale. Example: “25 °C or 100 °C”.

Mathematical Formula

BJS recommends carefully following the rules for Mathematical formulas:

Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y our X/Y/Z. In principle, variables are to be presented in italics. Number consecutively any equations that have to be displayed separately from the text.

Statistical Abbreviations

-Please do not italicize Greek letters. Examples: “α”, “χ³”.

-Italicize all other statistical symbols. Examples: “r”,’ r²”, “F”, “t” (as in t-test or Tukey’s test).

-Sample size: lower case and italicized. Example: “n = 10”.

-Mean or average: use “X” (capitalized and italicized) or spell out the word “mean” -SD = standard deviation, SE = standard error, CI = confidence interval; often indicated as “± SD”, “± SE”, “± 3 SE”, 100% CI = 1.40 - 6.70, etc.

-All statistical tests should include the test statistic, n or df, and P-value denoted as follows:

-For most test statistics, degrees of freedom should appear as subscripts (e.g., F₃,₅, t₄). Otherwise, they can be reported as “df” (e.g., “df = 8“).

-Probability: capitalize and italicize. Example: “P = 0.005.” When not significant, provide the value, rather than using “NS” or “P > 0.05.” Example: “P = 0.20”.

Mathematical Signs and Symbols

-Separate mathematical operators by spaces on both sides. Examples: “α = 0.05”; “P < 0.015”; “12 ± 0.03”.

-Separate a number from a symbol to indicate a mathematical operation. Example: “2 + 2 = 4”.

-Do not use a space between the “-“ and the “+” when indicating positive or negative values.

Examples: “-5 °C”, “+10 mm”.

-The symbols for “similar to” and “nearly equal to” are not followed by space. Examples: “~21”, “≈35”.

-Use “log” for log base x (e.g. log base 10 would be log10) and “ln” for natural log.

-Use “male” and “female” or “M” and “F” NOT the symbols ♂ and ♀.

-In mathematical functions, fences typically go in this order: { [ ( ) ] }.

Chemistry Formula

Figures, Schemes, Tables and Structures should be drawn to fit single or double-column widths. They should look proportional in case they are reduced. Structures should be numbered with bold Arabic numerals, (e.g., 1, 2,...).

All chemical structures included in the manuscript should be drawn using the same letter type (Times New Roman), size of cyclic groups, size and thickness of chemical bonds, and, the most important, authors should use the same standard throughout the work, including all Figures, Schemes, Tables and Structures.

The following organic group abbreviations may be used: Me, Et, ⁿPr, ⁿBu, Ph, CO ²R, CO 2H and ⁱPrOH. One variable univalent substituent is indicated by R. When more than one independent variable general substituent is present, R¹, R², R³, etc. should be used. A variable metal may be indicated by M and variable ligands by L¹, L² or L1, L2, L3. Chemical formulas may also be given: H₂O, C-C, C=O, etc.

References to Drugs

BJS recommends for drug use to the rules:

The generic name of a drug should be used as a general rule; however, the full name or the commercial name of the drug, as well as the name and location of the supplier, may be given in addition if appropriate.

Bacterial, Fungi, Protozoa, Algae and Virus Nomenclature (Systematic)

(1) In general for bacterial

Microbes should be referred to by their scientific names according to the binomial system used in the latest edition of Bergey's Manual of Systematic Bacteriology (The Williams and Wilkins Co.) (https://www.springer.com/series/4157). When first mentioned, the name should be in full and written in italics. Thereafter, the genus should be abbreviated to its initial letter, e.g. Staphylococcus aureus > S. aureus NOT Staph. Aureus. If abbreviation is likely to cause confusion or render the intended meaning(s) unclear the names of organisms should be given in full.

Or when there is a serotype: Salmonella enterica subsp. enterica serovar Typhimurium.

For studies with fungi, protozoa, algae and viruses, follow the guidelines of the American Society of Microbiology, Manual of Clinical Micribiology.

(2) In general for Fungi:

In the text where it is cited for the first time, describe the full name and its repetition, using an abbreviation. Example (Synchytricum endobioticum and its repeat S. endobioticum or Candida albicans and its repeat C. albicans. Recommends using Species Fungorum or Bergey's Manual of Systematic Bacteriology (The Williams and Wilkins Co.).

(3) In general for Protozoa:

For studies involving protozoa, BJS recommends using The World of Protozoa, Rotifera, Nematoda and Oligochaeta.

(4) In general for Algae:

For studies involving algae, BJS recommends using Algae Identification and Nomeclature (Lab Guide) or Manual on Harmful Marine Microalgae.

(5) In general for Virus:

For studies involving viruses, BJS recommends using Virus Taxonomy (National Library of Medicine) (NIH), or Encyclopedia of Virology - Fourth Editon, v. 1, p. 28-37, or Center for Management and Strategic Studies (CGEE).

Footnotes

Footnotes should be used sparingly. Number them consecutively throughout the article. Many word processors can build footnotes into the text, and this feature may be used. Otherwise, please indicate the position of footnotes in the text and list the footnotes themselves separately at the end of the article. Attention: It is recommended to use a hyperlink in the numbering. Do not include footnotes in the Reference list.

Accession Numbers of RNA, DNA, Protein Sequences and Enzymology Data

Accession numbers of RNA, DNA and Protein sequences used in the manuscript should be provided in the Materials and Methods section (Template article). Also see the section on:

(1) New nucleic acid sequences must be deposited into an acceptable repository such as GenBank, DDBJ, and EMBL. Important Note: Sequences should be submitted to only one database.

(2) New high throughput sequencing (HTS) datasets (RNA-seq, ChIP-Seq, degradome analysis, among others) must be deposited either in the GEO Database or in the NCBI’s Sequence Read Archive (SRA).

(3) New microarray data must be deposited either in the Gene Expression Omnibus (GEO) or the ArrayExpress databases (BioStudies.).

Depositon of Proteomics Data

Reporting guidelines for proteomics. Methods used to generate the proteomics data should be described in detail and the BJS recommends that the author adhere to the Minimum Information About a Proteomics Experiment (MIAPE).

 All generated Mass Spectrometry (MS) raw data must be deposited in the appropriate public database such as ProteomeXchange – Center for Computational Mass Spectrometry (CCMS), PRoteomics IDEentifications Database (PRIDE) or Japan Proteome Standard Repository/Database (jPOST). Special note: include the information in only one database!

At the time of submission, please include all relevant information in the materials and methods section, such as repository where the data was submitted and link, data set identifier, username and password needed to access the data.

Deposition of Crystallographic Data

When submitting the article with crystallographic data included, the author(s) must deposit, in the relevant Data Center, the data corresponding to each structure to be reported. Data for organometallic, inorganic, organic and coordination (Werner-type) compounds should be sent to the joint (CCDC/FIZ Karlsruhe) online deposition service (https://www.ccdc.cam.ac.uk/Community/depositastructure/), in CIF format. Cambridge Crystallographic Data Centre (CCDC) (https://www.ccdc.cam.ac.uk/). FIZ Karlsruhe Leibniz-Institut Für Informationsinfrastruktur (https://www.fiz-karlsruhe.de/).

CheckCIF

During submission of a manuscript to the Brazilian Journal of Science, authors should provide CCDC/FIZ reference numbers as Supplementary Information (separate file). Any revised CIF generated during the editorial process should be deposited directly with the CCDC before the revised manuscript is submitted the BJS.

During submission, authors are required to provide a checkCIF report for their crystal data together with the manuscript files. This report can be obtained via the free (CheckCIF service) provided by the International Union of Crystallography (IUCr). Any occurrence that produces ‘level A’ and ‘level B’ alerts in the checkCIF should be dealt with in the manuscript or well justified before acceptance of the manuscript can be considered.

NMR, IR and Mass Spectra Data

Whenever a compound is synthesized or identified (new or already known), it is imperative to send all spectral data (data and spectra) as Supplementary Information (SI) along with your submission.

Attention: Do not forget to add captions to each one of them, identifying each individual spectrum (e.g., Figure S1. 1H NMR Spectrum of...; Figure S2. IR Spectrum of...; Figure S3. 13C{1H}Spectrum of...; Table S1. Data for…). If the spectra will be digitalized (scanned), choose options: black&white, without background and 300 dpi at least.

Research Involving Cell Lines

Attention: Material and Methods section for submissions reporting on research with cell lines should state the origin of any cell lines. For established cell lines the provenance should be stated and references must also be given to either a published paper or to a commercial source.

If previously unpublished de novo cell lines were used, including those gifted from another laboratory, details of institutional review board or ethics committee approval must be given, and confirmation of written informed consent must be provided if the line is of human origin.

An example of Ethical Statements:

The HCT116 cell line human was obtained from XXXX. The MLH1+ cell line was provided by XXXXX, Ltd. The DLD-1 cell line was obtained from PhD. XXXX. The DRGFP and SAGFP reporter plasmids were obtained from PhD. XXX.

Borders and Territories

Potential disputes over borders and territories may have particular relevance for authors in describing their research or in an author or editor correspondence address, and should be respected.

Content decisions are an editorial matter and where there is a potential or perceived dispute or complaint, the editorial team will attempt to find a resolution that satisfies parties involved.

Attention: The BJS stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.
