An abbreviation is a shortened form of a word or phrase, by any method. It may consist of a group of letters or words taken from the full version of the word or phrase; for example, the word abbreviation can itself be represented by the abbreviation abbr., abbrv., or abbrev.; NPO, for nil per (by) os (mouth) is an abbreviated medical instruction. It may also consist of initials only, a mixture of initials and words, or words or letters representing words in another language. Some types of abbreviations are acronyms or grammatical contractions or crasis.
The Diagnostic and Statistical Manual of Mental Disorders is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria. It is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the principal guides of psychiatry, along with the ICD, CCMD, and the Psychodynamic Diagnostic Manual. However, not all providers rely on the DSM-5 as a guide, since the ICD's mental disorder diagnoses are used around the world and scientific studies often measure changes in symptom scale scores rather than changes in DSM-5 criteria to determine the real-world effects of mental health interventions.
Studies that are in vivo are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism. This is not to be confused with experiments done in vitro, i.e., in a laboratory environment using test tubes, Petri dishes, etc. Examples of investigations in vivo include: the pathogenesis of disease by comparing the effects of bacterial infection with the effects of purified bacterial toxins; the development of non-antibiotics, antiviral drugs, and new drugs generally; and new surgical procedures. Consequently, animal testing and clinical trials are major elements of in vivo research. In vivo testing is often employed over in vitro because it is better suited for observing the overall effects of an experiment on a living subject. In drug discovery, for example, verification of efficacy in vivo is crucial, because in vitro assays can sometimes yield misleading results with drug candidate molecules that are irrelevant in vivo.
The Chicago Manual of Style is a style guide for American English published since 1906 by the University of Chicago Press. Its 17 editions have prescribed writing and citation styles widely used in publishing.
A citation is a reference to a source. More precisely, a citation is an abbreviated alphanumeric expression embedded in the body of an intellectual work that denotes an entry in the bibliographic references section of the work for the purpose of acknowledging the relevance of the works of others to the topic of discussion at the spot where the citation appears.
APA style is a writing style and format for academic documents such as scholarly journal articles and books. It is commonly used for citing sources within the field of behavioral and social sciences, including sociology, education, nursing, criminal justice, and anthropology, as well as psychology. It is described in the style guide of the American Psychological Association (APA), which is titled the Publication Manual of the American Psychological Association. The guidelines were developed to aid reading comprehension in the social and behavioral sciences, for clarity of communication, and for "word choice that best reduces bias in language". APA style is widely used, either entirely or with modifications, by hundreds of other scientific journals, in many textbooks, and in academia. The current edition is its seventh revision.
In English-language punctuation, a serial comma is a comma placed immediately after the penultimate term in a series of three or more terms. For example, a list of three countries might be punctuated as either "France, Italy and Spain" or "France, Italy, and Spain".
The Council of Science Editors (CSE), formerly the Council of Biology Editors and originally the Conference of Biology Editors, is a United States-based nonprofit organization that supports editorial practice among scientific writers. In 2008, the CSE adopted the slogan "CSE: Education, Ethics, and Evidence for Editors (E4)".
Title case or headline case is a style of capitalization used for rendering the titles of published works or works of art in English. When using title case, all words are capitalized, except for minor words that are not the first or last word of the title. There are different rules for which words are major, hence capitalized. As an example, a headline might be written like this: "The Quick Brown Fox Jumps over the Lazy Dog".
Parenthetical referencing is a citation system in which in-text citations are made using parentheses. They are usually accompanied by a full, alphabetized list of citations in an end section, usually titled "references", "reference list", "works cited", or "end-text citations". Parenthetical referencing can be used in lieu of footnote citations.
Sentence spacing concerns how spaces are inserted between sentences in typeset text and is a matter of typographical convention. Since the introduction of movable-type printing in Europe, various sentence spacing conventions have been used in languages with a Latin alphabet. These include a normal word space, a single enlarged space, and two full spaces.
MLA Handbook, formerly MLA Handbook for Writers of Research Papers (1977–2009), establishes a system for documenting sources in scholarly writing. It is published by the Modern Language Association, which is based in the United States. According to the organization, their MLA style "has been widely adopted for classroom instruction and used worldwide by scholars, journal publishers, and academic and commercial presses".
The Vancouver system, also known as Vancouver reference style or the author–number system, is a citation style that uses numbers within the text that refer to numbered entries in the reference list. It is popular in the physical sciences and is one of two referencing systems normally used in medicine, the other being the author–date, or "Harvard", system. Vancouver style is used by MEDLINE and PubMed.
Gene nomenclature is the scientific naming of genes, the units of heredity in living organisms. It is also closely associated with protein nomenclature, as genes and the proteins they code for usually have similar nomenclature. An international committee published recommendations for genetic symbols and nomenclature in 1957. The need to develop formal guidelines for human gene names and symbols was recognized in the 1960s and full guidelines were issued in 1979. Several other genus-specific research communities have adopted nomenclature standards, as well, and have published them on the relevant model organism websites and in scientific journals, including the Trends in Genetics Genetic Nomenclature Guide. Scientists familiar with a particular gene family may work together to revise the nomenclature for the entire set of genes when new information becomes available. For many genes and their corresponding proteins, an assortment of alternate names is in use across the scientific literature and public biological databases, posing a challenge to effective organization and exchange of biological information. Standardization of nomenclature thus tries to achieve the benefits of vocabulary control and bibliographic control, although adherence is voluntary. The advent of the information age has brought gene ontology, which in some ways is a next step of gene nomenclature, because it aims to unify the representation of gene and gene product attributes across all species.
The Users’ Guides to the Medical Literature is a series of articles originally published in the Journal of the American Medical Association, later rewritten and compiled in a textbook, now in its third edition. The guides provide practical, clinician-friendly advice on all aspects of evidence-based medicine.
Sentence spacing guidance is provided in many language and style guides. The majority of style guides that use a Latin-derived alphabet as a language base now prescribe or recommend the use of a single space after the concluding punctuation of a sentence.
