INFORMATION FOR AUTHORS Download as PDF Scope and Overview Turkish Journal of Biochemistry (TJB), official journal of Turkish Biochemical Society, is issued electronically every 3 months. Research articles, reviews, short communications, technical reports, case presentations, opinions, and letters to the editor, that have not published elsewhere, on biochemistry, clinical biochemistry, molecular biology, molecular genetics, biotechnology, bioinformatics, bioengineering, and their educational disciplines are published in the journal. The main aim of the journal is to support the research and publishing culture by ensuring that every published manuscript has an added value and thus providing international acceptance of the “readability” of the manuscripts published in the journal. Compliance to the ethical principles on research and publishing are essential for the publication of manuscripts. Manuscripts should focus to their main aim, be clearly and concisely written, and adhere to grammar and general good writing principles. Authors should clearly declare any kind of conflict of interest related to the subject and/or any other author in both the abstract and Conflict of Interest sections. All manuscripts should be prepared in compliance with the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals” of International Committee of Medical Journal Editors (www.icmje.org ). Manuscripts and any other printed material published in the Turkish Journal of Biochemistry represent the opinions of authors and should not be construed to reflect the opinions of the Editorial Board and/or the Executive Committee of the Turkish Biochemical Society. Submitting Manuscripts are submitted electronically to the submission@turkjbiochem.com. Copyright Transfer Agreement and approval of Ethics Committee (if required) should be sent by post or by fax to the below information. Turkish Journal of Biochemistry Turk Biyokimya Dergisi Hirfanli Sokak 9/3 Gaziosmanpasa 06700 Ankara Fax: +90 312 447 09 63 Editorial correspondence other than manuscript submission can be sent to editor@turkjbiochem.com. If previously published material such as a table, figure, graphic, etc. is used exactly as the original, permission received from the publishers for this usage should also be sent; even though the material was published in a previous manuscript of the author(s). Editorial Board preliminary reviews the submitted manuscripts for compliance with the publishing concept and instructions of the journal, whether manuscripts are focused to their main aim, validity of the statistical method used, and adherence to ethical principles. Upon the preliminary evaluation, if required, manuscripts are sent back to the authors for revision. If revision is not required or upon the completion of required editorial revision, manuscripts are sent to at least 2 reviewers specialized in the topic and concept of the manuscript. Editorial Board makes sure that there is no conflict of interest while assigning the reviewers and names of the authors are not declared to the reviewers. Authors should clearly declare any kind of conflict of interest related to the subject and/or any other author in the abstract and Conflict of Interest sections. Members of the Scientific Advisory Board and other scientists related to the topic of the manuscript are assigned as reviewers. All reviewers’ reports are sent to authors and the revisions of authors or their replies/opinions on reports are sent to the reviewers. Whether the manuscript will be published or not is decided upon the reviewers’ opinions. If there is an editorial opinion for publishing the manuscript, it is included as an additional reviewer. Publication Language Manuscripts should be either in English or Turkish. Title, abstract and keywords are published in both languages. For the authors who are not competent in Turkish, translations of the title, abstract, and keywords will be provided by the Editorial Board. Authors who are submitting a manuscript in English and whom main language is not English should consider that their manuscript, primarily the grammar of the manuscript, should adhere to the publishing expectations in order not to be rejected by technical editors.
