Major Techniques in Scientific Writing
  • Definition
  • Compare-contrast
  • Enumeration/Illustration
  • Cause-effect

Session 1
11
Characteristics of Scientific Writing (1)
  • English the universal language of science
  • - Eugene Garfield, 1987
  • Reader-oriented ---- Sharing information
  • Three Things to Avoid
  • Laboratory jargon
  • Invented words
  • Non-standard abbreviations
  • Purposeful ---- Convey information, ideas,
    concepts
  • Precise ---- Choose words meant to be said
  • Accurate ---- Conformity, actual (true) state

Session 1
12
Characteristics of Scientific Writing (2)
  • Clear
  • Reaches the audience with the same meaning it had
  • Should NOT be interpreted in more than one way
    ---- Avoid
  • When something is said for the first time,
    clarity is essential.
  • Concise
  • Expresses, covers much in few words
  • The best English is that which gives the sense in
    the fewest short words. Instructions to
    Authors, Journal of Bacteriology.
  • Simple ---- Easy to understand, not elaborate or
    artificial, not ornate, not complicated
  • Illustrated ---- A picture is worth a thousand
    words. Make use of good figures and tables

Session 1

Sins of Language
excess
omission
Misunderstanding Misleading Harm
dishonesty
ignorance
malice
Session 1
14
Characteristics of a Valid Manuscript (1)
  • First report of the data (original paper)
  • Original research results (not me-too)
  • Allow peers to repeat the reported experiments
    (not necessarily the results)
  • Publish in a journal or other public source
    document
  • Available to the scientific community
  • Be received and understood

Session 1
15
Characteristics of a Valid Manuscript (2)
  • Characteristic format ---- IMRAD
  • (Introduction, Methods ( Materials), Results,
    and Discussion)
  • Introduction What question was studied?
  • Methods How was it studied?
  • Results What were the findings?
  • Discussion What do the findings mean?
  • This logic helps the author organize and write
    the manuscript.
  • Traditional format
  • Cancer Research
  • PNAS USA
  • Alternative format Introduction, Results,
    Discussion, and Methods ( Materials)

Ten (10) Key Questions
  • Is there a story to tell?
  • What was the rationale for the project?
  • Did I perform a thorough literature review?
  • What is the historical context of the work?
  • Did I have a clear hypothesis?
  • Did the experiments test that hypothesis?
  • Is the experimental design defendable?
  • Can I justify what I did?
  • Did I use appropriate controls?
  • How do my findings relate to the existing
    knowledge?

Session 1
18
Steps in Writing a Manuscript (2)
  • Search and Review the Literature
  • Use MEDLINE other sources
  • Search using all appropriate keywords
  • Summarize relevant points of related articles
  • Prepare an Outline
  • Preparation forces you to think and organize.
  • All points should be supported by appropriate
    data.
  • Gives a logical, step-by-step order in which the
    manuscript will be presented.
  • Gaps can be filled in, and extraneous material
    can be eliminated.
  • Writing can be done with less interruption.

SCI and Impact Factor
  • Myths of Impact Factors (IFs)
  • IFs do not reflect the quality of individual
    papers.
  • Review journals generally have higher IFs.
  • IFs are biased against some specialty or new
    fields of research.
  • Not all journals are included in the index.
  • IFs can be manipulated by editors/publishers.
  • IFs fluctuate year to year for a given journal.
  • Journals originated from Non-English country
    generally have lower IFs
  • IFs cannot be used to compare publications in
    different fields (subject category)
  • Simple math does not work here
  • IF 10 IF1 X10?
  • IF 5 IF5 IF10?
  • IF 10X 6 IF60?
  • IF 5.614 is better than IF 5.613?

Major Secondary Services
  • Is it recognized by one or more of the major
    secondary services (Chemical Abstracts,
    Biological Abstracts, MEDLINE/PubMed)?
  • MEDLINE (Medical Literature Analysis and
    Retrieval System Online) is an international
    literature database of life sciences and
    biomedical information. It covers the fields of
    medicine, nursing, pharmacy, dentistry,
    veterinary medicine, and health care and much of
    the literature in biology and biochemistry.
    (5000 serials)
  • PubMed is a free search engine offering access
    to the MEDLINE database of citations and
    abstracts of biomedical research articles. It
    also provides access to many pre-1966
    publications.
  • CA (Chemical Abstracts Service), a division of
    the American Chemical Society, produces Chemical
    Abstracts, an index of the scientific literature
    in chemistry and related fields. (9500 serials)
  • Biological Abstracts directs users to
    information on life science topics, ranging from
    botany to microbiology to pharmacology. (gt3700
    serials)

More than IF
  • What is the prestige of the journal?
  • Is it a primary journal?
  • Is it an open journal?
  • What is the circulation of the journal?
  • What is the review time for the journal?
  • What is the publication time for the journal?

Most Journals publish the dates of submission,
review, and acceptance. You need to check the
publishing date Epub ahead of print In press
MS Open access online only PubMED submission
etc.

Select an Appropriate Journal (6)
More than IF
  • Who will be interested in reading the paper
    basic scientists, clinicians, or both?
  • Whom do you want to read the paper members of
    the funding committee, the promotion committee,
    or the competitors?
  • Is the paper within the Scope of the journal
    (in the Instructions for Authors ).
  • Be familiar with the journal, especially papers
    published in the last 6-12 months

Still not sure Ask a trusted peer, and, if
possible, be acquainted with the editor.
Session 1

Select an Appropriate Journal (7)
Knew What You Wish For
  • Check recent articles in various journals
    examine their format and content.
  • Examine several articles in potential journals.
    How many figures and tables do they have?
  • Read the Table of Contents of recent issues of
    potential journals.
  • Consider Am I qualified to write an article for
    this journal?
  • Consider Where were the papers you will cite as
    references published-were they published in a
    similar quality journal?
  • Read the Instructions for Authors and examples
    of publications in these journals.

Keep in Mind Topic, Contents, Format, and Style.
Session 1
34
Select an Appropriate Journal (8)
Wrong Journal or Wrong Paper?
  • If you submit to a wrong journal
  • Your manuscript may be returned to you without
    review.
  • It may be reviewed inadequately.
  • Its publication may be unnecessarily delayed.
  • Your work may remain unknown because it is not
    read after publication.

Still not sure Ask the Editor of the potential
journal. Do not overly depend on Professional
Editing Service
Session 1
35
Data Preparation and Evaluation (1)
  • Checklist for finalizing data for a manuscript
  • Make sure your results have been
    repeated/confirmed
  • Select results that are representative of your
    repeats (for Western blots, photographs, spectra,
    etc) or prepare averages and standard deviations
    for your data (clinical parameters, animal
    studies, etc.)
  • Ensure that your data are statistically
    significant, and that you indicate this in the
    text and figures.
  • Prepare an appropriate number of figures and/or
    tables (many journals have a limit of 6 figures)
  • Confirm that your figures and tables are
    supported by raw data
  • Make sure that the raw data is retrievable (in
    laboratory records)
  • Organize data by importance (key data,
    supporting evidence, and/or supplemental data)
  • Determine they type of illustration that will
    best showcase the data (Figure? Table?
    Photograph?)
  • Generate figures of sufficient quality for your
    selected journal (journals frequently require
    figure quality of 600 dpi)
  • Format your illustrations according to the
    instructions for authors (font style and size)
    and, if possible, use a consistent size and style
    for each figure and table
  • Avoid redundancy between tables, figures and the
    text
  • The corresponding author needs to check the
    quality and accuracy of the data, and that the
    data is supported by raw data
  • The figures and tables should indicate
    statistical significance (if applicable)
  • Prepare supplemental illustrations (if applicable
    for your journal)
  • Write figure and table legends (the legends
    should describe the figure and methods in
    sufficient detail so that the reader knows what
    the data indicate and how they were obtained)
  • Check all the materials and methods and/or key
    references

Session 1
36
Data Preparation and Evaluation (2)
  • Q Do I need All the data before beginning the
    writing
  • No
  • But You need
  • All Key data
  • Most supporting data
  • Some supplemental data
  • You need ALL the data before the completion of
    the first draft
  • You still can add data before final submission

You should evaluate your data periodically and
prepare your outline and key data as soon as
possible.
Session 1
37
Data Preparation and Evaluation (3)
  • Q Who should evaluate and check the data?
  • All the authors
  • Key persons
  • Primary authors
  • Corresponding author
  • Technical staff
  • Collaborators
  • You may ask trusted colleagues to evaluate the
    data

Hot topic Can you trust the internet to send
your unpublished data?
Session 1
38
Data Preparation and Evaluation (4)
  • Q Does the format of the data presentation
    matter?
  • Yes
  • You can present your data in various manners
  • Table
  • Simple
  • Complex
  • Number of the tables
  • Figure
  • Color?
  • Number of the figures
  • Number of panels in a figure
  • Text
  • The best way is to use all the above, but not
    redundant

Hot Topic The art of scientific data presentation
Session 1
39
Data Preparation and Evaluation (5)
  • Q Why is statistical analysis so important?
  • The following statements are frequently based on
    statistical analysis
  • Significant
  • Effective
  • Correlation/relation
  • Causal relation
  • Safe
  • Better or Worse
  • Confirm or rule out a hypothesis
  • Prediction/Extrapolation
  • Other
  • You Almost Always need help from a statistician,
    from planning to design to analysis to reporting
  • It is almost too late if the reviewer/editor
    requests statistical analysis for your paper.

Hot topic You should know the difference between
statistical significance and biological
significance.

43
Introduction/Background (1)
  • Every Paper needs an Introduction section
  • Original Article
  • Review Article
  • Case Report
  • Technical/Method Report
  • Letter
  • Editorials
  • Other
  • This section is a critical showcase.
  • May be written late in the process, e.g., after
    you complete Results and Methods section.

Session 2
44
Introduction/Background (2)
  • The first sentence should stimulate the interest
    of the reader.
  • Example 1
  • Poor The purpose of this article is to show that
    case management can be a cost-effective approach
    in patient care. (unnecessary words)
  • Improved Case management can be a cost-effective
    approach in patient care.

Session 2
45
Introduction/Background (3)
  • The first sentence should stimulate the interest
    of the reader.
  • Example 2
  • Poor From the beginning of time, strokes have
    been a major health problem. (trite, negative)
  • Improved Advanced treatments for stroke patients
    are giving them new hope.

Session 2
46
Introduction/Background (4)
  • Three Important components in this section.
  • The topic to be covered and why it is important
    (The rationale)
  • The purpose of the studies.
  • The hypothesis that led to the investigation.

Session 2
47
Introduction/Background (5)
  • Try to state
  • Whats new?
  • Whats special?
  • Whats significant?
  • How to do it?
  • Provide a brief review of the literature and cite
    findings that led to the present studies.
  • Example
  • Good In inner-city adolescents, the increased
    incidence of illnesses related to sexuality
    demonstrates a lack of understanding of these
    problems. Through counseling and referrals, nurse
    practitioners in our hospital developed a
    procedure to reach this population and reduce the
    occurrence of these diseases.

Session 2
48
Introduction/Background (6)
  • This section should be short 500-1000 words.
  • How to do it?
  • Discuss any unknowns and controversies that exist
    , with respect to the rationale for the studies.
  • The information should be fresh/novel,
    interesting, and specific.
  • Much of the Introduction should be written in the
    present tense, when you mention the published
    data/hypothesis.
  • This section is best written in the active voice.
    The active voice gives writing a sense of
    strength, energy, and direction. (It is also
    20-30 shorter than the passive voice.)

Session 2
49
Introduction/Background (7)
  • You need a clearly stated HYPOTHESIS and
    Approaches.
  • How to do it?
  • State the hypothesis directly.
  • Set up the problem and show how it was dealt
    with.
  • It is acceptable to briefly state the conclusion.
  • Use only the most important references. Do not
    refer to individual scientists unless it is
    necessary to contrast results from different
    laboratories. (This principle applies also to
    other sections of the manuscript.)
  • Preliminary reports should be mentioned.
  • If there are related publications that will be
    published soon, they should be mentioned. (But
    you need to check the journal format, with
    respect to unpublished data.)

Session 2
50
Introduction/Background Summary (1)
  • Include in this section
  • A brief review of the field (1 paragraph),
    including a description of areas in the specific
    field that are unclear or uncharacterized.
  • An introduction to the present study (1
    paragraph), including hypothesis, major models
    and readouts, and key conclusions
  • A brief comparison of the present study to the
    current knowledge, concluding with the
    significance and possible impact.
  • A simple figure for testing system or agents that
    are new to the field, e.g., structure for a newly
    identified chemical that has been published.

Session 2
51
Introduction/Background Summary (2)
  • DO NOT include in this section
  • A lengthy review of the field or related fields
  • Methods used for the paper
  • For papers detailing the discovery or
    design of a new method, this may sometimes be
    mentioned.
  • Results
  • Discussion
  • Unrelated materials
  • Complex table or figures

Session 2
52
Introduction/Background Summary (3)

    Abstract or other sections, especially the
    discussion section.
  • Inclusion of references that are not generally
    available, such as non-English publications
  • Too short or too long
  • Overly negative to studies of other groups
  • Over-emphasize previous studies from the same
    group and or ignore studies from other groups
  • Including complex table or figures

Session 2
53
Materials and Methods (1)
  • General Suggestions
  • For beginning authors, this section can be
    written first because it is easiest to write.
  • The format is usually specific to the journal.
  • Subheadings are characteristically used.
  • Much of this section is written in the past
    tense, passive voice.
  • Much of this section can be included in the
    supplementary data section
  • This section can be placed after the Discussion
    section in many journals.

Session 2
54
Materials and Methods (2)
  • This section should be specific, providing
    sufficient details that allow an experienced
    researcher in the related field to repeat the
    experiments in this study.
  • How to do it?
  • Provide sources of key materials and describe
    preparation of non-standard solutions.
  • Experimental animals, plants, and microorganisms
    should be identified by genus, species, and
    strain, as well as age. Sources should be listed
    and special characteristics described.
  • For human subjects, the criteria for selection
    should be described, and a statement relating to
    informed consent should be included.
  • Provide sufficient details of the experiments.
    Descriptions of new methods should include all
    the needed details. If the methods have been
    published, references to the specific
    publications can be used. Do not describe
    previously published procedures in long detail,
    but do describe any modifications.
  • Describe the study design and procedures for
    analysis of the data.
  • Provide information on statistical analyses
    performed and state the number of observations in
    each group.

Session 2
62
Results (5)

Illustrations (3)
  • General Suggestions for Graphs
  • If you choose to use a graph, it should convey
    information better than a text or a table.
  • Graphs should be understood without referring to
    the text.
  • Graphs show trends, overall patterns, and
    interactions between variables.
  • Graphs demonstrate change over time or
    concentration.
  • Graphs do not emphasize individual values.
  • Graphs should avoid wasted space.
  • Place the independent variable on the x-axis and
    the dependent variable on the y-axis.
  • On both axes, plot the length of intervals so
    that the curves are not excessively flat or
    steep.
  • Captions should be concise, contain key words,
    and be parallel for all graphs in the manuscript.
    Captions should not be sentences.
  • The number of curves on a graph should be limited
    to five.
  • It is generally better to use symbols (?, , ?)
    than line patterns.
  • The curves should be bold and easy to see the
    axes and tic marks can be smaller/less bold , but
    should still be easy to see.

    the paper, including the following
  • the background (1-3 sentences)
  • the hypothesis (1 sentence)
  • model systems used
  • general methods
  • a short description of the results

    tense, especially methods and results .
  • Within the space allowed, all key findings should
    be included.
  • It should ordinarily be written after a
    semi-final draft of the manuscript has been
    prepared.

  • Terms included in the abstract will be included
    in various databases for literature searches.
  • Importance of the Abstract Its contents can
    establish the interest of the editor and
    reviewers and will determine if the reader
    actually reads the manuscript. Editors will
    often use the abstract to determine whether the
    paper should be reviewed for their journal. After
    the paper is published, readers may read only the
    abstract.

Abstract (7)
  • Example
  • Down-regulation of p53 by MDM2-mediated
    proteasomal degradation makes cells resistant to
    apoptosis. The MDM2-p53 interaction is well
    characterized, but the mechanisms that regulate
    the interaction are not well understood. Here, we
    show that PA28?, a proteasome activator that
    inhibits apoptosis and promotes cell cycle
    progression through unknown mechanisms, exerts an
    effect as a cofactor in the MDM2-p53 interaction.
    The polymer form of PA28? interacts with both
    MDM2 and p53 proteins and facilitates their
    physical interaction. This promotes
    ubiquitination- and MDM2-dependent proteasomal
    degradation of p53, limiting its accumulation and
    resulting in inhibited apoptosis after DNA
    damage. Elimination of endogenous PA28? in human
    cancer cells abrogates MDM2-mediated p53
    degradation, increases the activity of p53, and
    enhances apoptosis. These findings reveal the
    mechanism by which PA28? affects apoptosis and
    proliferation. Manipulation of the level of
    PA28?, an approach that would regulate the
    cellular content of p53, may improve the efficacy
    of current cancer therapies.
