Editorial Boardof theProceedings

INFORMATION TO CONTRIBUTORS

(Revised 1978)Purpose and scopeThe Proceedings of the National Academy of Sciences USApublishes reports that describe the results of original theoreticalor experimental research of exceptional importance or novelty.Reports are accepted only if contributed by a member or for-eign associate of the Academy or communicated by an Acad-emy member or foreign associate on behalf of a nonmemberand if they have not been submitted for publication or pre-viously published elsewhere. Communicated papers shouldbe of a high scientific quality such as to place them in the top10th percentile of their field.Because the PROCEEDINGS publishes papers in all branches

of science represented in the Academy, articles should be ofinterest and intelligible to a broad scientific audience.

Occasionally, preliminary findings of major importance maybe published in the PROCEEDINGS without full documentation;in such cases, the author must indicate the preliminary char-acter of the paper and where a subsequent detailed report willbe published.Upon invitation from the Editorial Board, papers presented

at Academy symposia, special Academy lectures, reviews, orpapers on subjects of general interest to scientists are also pub-lished in the PROCEEDINGS.

Procedures for submitting manuscriptsManuscripts should be sent, in duplicate, to the PROCEEDINGSOF THE NATIONAL ACADEMY OF SCIENCES USA, 2101 Con-stitution Avenue, Washington, DC 20418. Manuscripts thatmeet the criteria listed below are usually published within 8-13weeks. However, as authorized by the Bylaws of the Academy,the Editorial Board reserves the right to subject manuscripts tofurther review when necessary and to reject those that do notmeet the general criteria for publication or are regarded asinappropriate in some significant way.Members or foreign associates of the National Academy of

Sciences who submit manuscripts assume responsibility for thepropriety and scientific standards of the manuscripts that theysubmit. Each one may contribute and/or communicate amaximum of 10 papers in any calendar year.New members or foreign associates may submit manuscripts

as soon as a letter of membership acceptance is received by theHome Secretary's Office.

In general, no person may be an author or coauthor of paperstotaling more than five pages in any one issue.

Before communicating an article on behalf of nonmember(s),an Academy member must obtain signed written opinions ofthe paper from two qualified referees. Only the member shouldselect the referees; their names need not be divulged to theauthor. Referees should be chosen solely for their impartialityand their ability to judge the work. Forms for the referees'comments are provided to members on request to the PRO-CEEDINGS Office. An author should see all referee commentsbefore the paper is forwarded to the PROCEEDINGS Office.Signed copies of both referee reports must accompany themanuscript. The member may communicate a paper for whicha referee report is unfavorable, but the reasons for so doingshould be stated.

Because only members or foreign associates are privilegedto communicate manuscripts to the PROCEEDINGS, the letterof communication must come from the member. In the letterof communication on behalf of a nonmember, the membershould indicate explicitly that the report is particularly novel,of exceptional importance, or of broad interest to diverse groupsof scientists. In addition, if a nonmember is to be billed for pagecharges ($85; in 1979, $95), then the member should identify

which author has agreed to pay the charges; otherwise, theAcademy member is responsible for the cost of publication.Authors are also billed for the costs of extensive changes madein proof, for color reproductions, and for other special items.The name and telephone number of the specific author re-

sponsible for reviewing the galley proof should be given.Manuscripts that report research involving either human

subjects or the use of materials of human origin must be ac-companied by a copy of the document authorizing the proposedresearch, issued and signed by the appropriate official(s) of theinstitution where the work was conducted. Authors are referredto the Declaration of Helsinki for further guidance.

For animal experimentation reported in the PROCEEDINGS,it must be clear that the conditions conformed to the GuidingPrinciples in the Care and Use of Animals approved by theCouncil of the American Physiological Society.

Manuscripts that report recombinant DNA research shouldstate, in the Materials and Methods section, the physical andbiological containment levels used, as outlined in the "NationalInstitutes of Health Recombinant DNA Research Guidelines,Part II" (see Federal Register, July 7, 1976).When reference is made to a personal communication, un-

published work, or a paper in press that does not involve at leastone author of the manuscript sent to the PROCEEDINGS, it is thesubmitting author's responsibility to furnish a statement thatauthorizes the citation of such material and is signed by one ofthe persons cited.No manuscript in any scientific discipline is exempt from

these requirements and the requirements for manuscriptpreparation noted below. Failure to provide all the necessarydocumentation when the manuscript is submitted may delaypublication.

Receipt of each manuscript is acknowledged by the PRO-CEEDINGS Office. Academy members or authors should callthe PROCEEDINGS Office if they have questions. The telephonenumber is (202) 389-6871. When calling on manuscript-relatedmatters, an author should indicate the manuscript number andscheduled month of publication.

Manuscript preparationLength. Articles should be as brief as full documentation

allows. They may not exceed five printed pages (approximately5000 words). (Review articles may be up to eight pages.) Thetitle, key terms, names of authors and their affiliation(s), andstatement of communication or contribution usually occupyspace equal to about 250 words. Appropriate allowance mustbe made for the space occupied by footnotes, references, tables,and figures with their legends. Final size of figures is decidedin the PROCEEDINGS Office to make the best use of space; au-thors' suggestions will be considered (see Illustrations, below).Instructions for calculating the length of a manuscript areavailable from the PROCEEDINGS Office. However, responsi-bility for final measurements of manuscript length is retainedby the PROCEEDINGS Office.

Articles estimated to exceed five pages will be returned forshortening, without further editorial consideration.

Manuscripts must be typed, double-spaced throughout, ononly one side of each page.

Title Page. Provide a title page containing only the followinginformation:

Classification. Give any one of the sciences named in thetitles of the Academy Sections with these exceptions: Sections41 (Medical Genetics, Hematology, and Oncology), 42 (MedicalPhysiology, Endocrinology, and Metabolism), and 43 (InfectiousDiseases and Immunology) are all listed as Medical Sciences;

and Section 27 (Population Biology, Evolution, and Ecology)may be listed as Population Biology, Evolution, or Ecology.Additional headings that may be used but that are not AcademySections are Biophysics, Immunology, Microbiology, and Sta-tistics.

Title. The title should be brief, specific, and rich in infor-mativer words. Titles usually should not begin with such generalwords as "The," "A," "Results," "Study," or "Effect."

Titles should not include phrases in which more than threewords modify another word (e.g., "simian virus transformedfetal mammalian heart fibroblast" should be written as "simianvirus-transformed fibroblast from fetal mammalian heart").The PROCEEDINGS does not use serial titles such as On Steroids,XIX. A serial title followed by a colon and the specific title maybe used (e.g., On steroids: Metabolism of cortisone). If a paperis part of a series, this may be indicated by a symbol at the endof the title and a footnote: "This is paper no. 19 in a series. Paperno. 18 is ref. _" The preceding paper must then be in-cluded in the list of references.Key Terms. These terms should be given below the title,

enclosed within parentheses, and separated by a slash (/) mark.Up to five terms, composed of words not used in the title, maybe included to alert readers and indexers to other subjects in thepaper.Author Affiliation. The department, institution, city, state,

and ZIP code or country for each author should be furnished.If there are'several authors with different affiliations, authorsshould be matched to their respective institutions by means ofsuperscript symbols after the authors' names in this order: *, t,$ §1¶11

If an author has moved since doing the work described, in-dicate the institution at which the work was done in the primaryaffiliation listing and use an additional symbol and footnote toindicate the present address.

If reprint requests are to be addressed to an author other thanthe first one listed, also indicate this with a symbol as notedabove and a footnote. The footnote should state: "To whomreprint requests should be addressed."

Abbreviations Footnote. Nonstandard abbreviations that areused five or more times throughout the paper should be listedin this section. The PROCEEDINGS discourages the use of ac-ronyms, and manuscripts will be edited so that abbreviationsare consistent with recommended international nomenclature.Nonstandard abbreviations should be kept to a minimum andshould not be used in the title, key terms, or abstract. Introducenonstandard abbreviations by defining where first mentionedin the text followed by the abbreviation in parentheses. Sub-sequently, the abbreviation only should be given.

Abstract Page. The second page of every paper must carryonly the abstract. The abstract should be no longer than 250words. It should state the subject and main conclusions of thearticle in generally intelligible terms. Abbreviations should beavoided unless used more than five times in the abstract. Theabstract must be understandable to the reader before he readsthe paper, suitable for reproduction without rewriting, andunambiguous without recourse to any other part of the manu-script.

Footnotes in Text. The number.of footnotes should be keptto a minimum and they should be indicated in text by use of asymbol. Symbols should be used in the order *, t, $, §,1, 11, butshould not repeat symbols used earlier, particularly those of thetitle page.Acknowledgments. All acknowledgments, including those

for financial support, should be cited here rather than in foot-notes..Acknowledgments to people usually precede those forgrant support. Abbreviations are not normally used except foran author's name, where only initials with periods are used.

References. Cite references in numerical order as they ap-

pear in the text. Tables and figures will be inserted in the textwhere first cited, so references in these sections should benumbered accordingly. Use Arabic numerals separated bycommas (except for sequences of three or more when a dash isused between the first and last numeral) and enclose the ref-erences in parentheses. References may not be cited in any otherorder.

Only papers that are either published or in press may be citedin the reference list. Each reference is given a separate number;multiple citations under one numeral are not used. Othercitations are either "unpublished data" or "personal commu-nication" and are shown directly in the text where first men-tioned.The full citation is given at the end of the manuscript. The

PROCEEDINGS requires inclusive pagination. If a reference isan abstract, then this should be noted in the citation, after thepage numbers.

Journal articles are cited as follows:10. Smith, A. B., Jones, C. D. & Robinson, E. F. (1969) Proc.

Natl. Acad. Sci. USA 64,191-195.For the correct abbreviations of journal titles, refer to eitherChemical Abstracts Service Source Index (CASSI) or Biblio-graphic Guide for Editors and Authors (1974). Both are pub-lished by the American Chemical Society, Washington, DC.

Articles or chapters in books are cited as follows:11. Jones, C. D. & Shapiro, L. M. (1966) in Enzyme Reactions

in Protozoa, eds. Smith, T. G. & Williams, H. I. (UniversalPress, New Brunswick, NJ), Vol. 21, pp. 646-672.

Authors are responsible for the accuracy of the citations.Tables. Tables should be prepared so that they are self-

explanatory. Vertical rules are not used to set columns apart,and horizontal rules are used sparingly. Tables should have abrief title and be numbered with Arabic numerals. Each tableshould be typed double-spaced throughout. Nonstandard ab-breviations should be used sparingly and must be defined in thelegend at the bottom of the table, if not defined in the abbre7viations section on the title page. Each vertical column requiresa heading. Reference to footnotes should be made by means ofthe symbols *, t, , § , 11, in that order. If more than six footnotesare required, then superscript lower-case letters should be used.For use of powers of 10, see section below.

Illustrations. Either original drawings or high-qualityphotographs are needed. Xerographic copies of illustrations arenot acceptable. When illustrations are reduced for publication,they should (i) fit into a one-column (83 mm) or two-column(175 mm) width and (ii) have letters no smaller than 1.5 mmin height. All illustrations should be identified on the reverseside by marking with a soft pencil. Where necessary, the ori-entation for the illustration should be indicated by an arrow andthe word "top." Legends for the illustrations should be typeddouble-spaced, in numerical order, on a separate page.

Line drawings should be marked with index lines and labeledwith scales on the x- and y-axes. Scales that involve large orsmall numbers should use numbers multiplied by powers of 10.The PROCEEDINGS uses the following convention: 3000 cpmis represented as 3 and the axis is labeled cpm X 10-3. Formaximal clarity, use both separate symbols and various lines(solid, broken, etc.). Keys to symbols and lines should be in-cluded in the legend, not on the figure. It is particularly im-portant that nomenclature, abbreviations, and units used infigures agree precisely with those used in the text of the paper.For electron micrographs and similar illustrative materials, thequality of reproduction cannot exceed the quality of the sub-mitted copy. Do not mount illustrations unless a compositefigure is required. A composite figure carries a single figurenumber; the individual parts may be identified by letters. In-dicate the magnification of photomicrographs in the legend orinclude a bar in the figure to indicate the scale (or both),

Abbreviations and Symbols. The PROCEEDINGS distin-guishes between standard and nonstandard abbreviations.Standard abbreviations for certain substances and units ofmeasure listed here do not need to be defined. Most otherabbreviations are considered to be nonstandard, should be keptto a mininum, and must be spelled out on first usage. Non-standard abbreviations should be used only for terms mentionedfive or more times in the paper (see Title Page), should beunambiguous, and should not simply be acronyms. Both stan-dard and nonstandard abbreviations should also conform tointernational standards. Authors should refer to: IUPACManual of Symbols and Terminology for PhysicochemicalQuantities and Units (1970) Butterworths, London, England;National Bureau of Standards Special Publication 330 (1974),eds. Page, C. H. & Vigoureux, P. (United States Government

Subject Index to Volume 75

JANUARY-DECEMBER 1978

IntroductionThe terms in the Subject Index for Volume 75, January-December 1978, of the

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES USA were chosen fromtitles, key terms, and abstracts of articles. The index terms are alphabetized bycomputer; numbers, conformational prefixes, Greek letters, hyphens, and spacesbetween words are disregarded in alphabetization. After each index term is printedthe title of the article (or a suitable modification of the title) and the appropriatepage number. Titles are listed in alphabetical order under the index terms.

Corrections to papers in which errors occurred are indexed under the term"Correction" and review articles are indexed under the term "Review" as well asunder the index terms selected for the paper itself. Organisms are indexed by theirscientific names when scientific names were provided in the papers; suitablecross-references are provided.

Because the PROCEEDINGS urges authors to follow the tentative rules and rec-

ommendations of the nomenclature commissions (e.g., for biochemistry, thoseproposed by the International Union of Pure and Applied Chemistry and theCommission on Biochemical Nomenclature), an effort has been made to constructan index that conforms with this policy. However, correction of errors in nomen-clature was not attempted and the index should not be looked upon as a referencefor correct or recommended usage. In addition, some exceptions to the recom-mendations of the commissions were necessary. Index terms themselves are usuallynot abbreviated even if specific recommendations have been made by the com-

missions; and in some instances, words within an index term were rearranged. (Thus,tRNA is indexed as "Ribonucleic acid, transfer.") In general, analogues of com-pounds are indexed as the parent compound. (Thus, dibutyryl adenosine 3':5'-cyclicmonophosphate is indexed as "Adenosine 3':5'-cyclic monophosphate, dibutyryl-.")The "Recommended Name" from the 1972 and 1975 recommendations of the In-ternational Union of Pure and Applied Chemistry and the International Union ofBiochemistry [Enzyme Nomenclature (1973) and Supplement 1 (1975), AmericanElsevier, New York] has been used for enzymes whenever Enzyme Commission (EC)numbers were published in the papers. EC numbers are listed as part of the entryonly if the EC number was printed in the paper. [Thus, some enzymes have twoentries, e.g., "Adenosinetriphosphatase" and "Adenosinetriphosphatase (EC3.6.1.3)."]
