Aims and scope:

The International Journal of Tryptophan Research is an international, open access, peer reviewed journal which covers all subjects related to Tryptophan research. There is no suitable journal that focuses on Tryptophan, and the IJTR aims to fill this void and provide a forum for those with interests in this area.

The journal also covers related precursors and metabolites such as serotonin, melatonin, niacin, tryptamine, kynurenine, and indoleamine 2,3-dioxygenase. Topics include isolation, functionality, interactions, analysis, synthesis and industrial production, as well as supplementation and role in diet, physiology, neurological disorders and immune response. However all articles related to Tryptophan are welcome.

Editorial standards and procedures:

All submissions to this journal, with the exception of editorials and dedications (obituaries), are subject to rigorous peer review by a minimum of two peer reviewers who demonstrate current research experience in the paper's subject area.  Reviewers are required to provide in-depth, fair and objective reviews.  They may not act as reviewers if they are in a conflict of interest.  All final publishing decisions are made by the Editor in Chief or Associate Editor.

Indexing:

This journal is indexed by:

• CAS

National Institutes of Health Public Access Policy compliant:

As of April 7 2008, the US NIH Public Access Policy requires that all peer reviewed articles resulting from research carried out with NIH funding be deposited in the Pubmed Central archive.

If you are an NIH employee or grantee Libertas Academica will ensure that you comply with the policy by depositing your paper at Pubmed Central on your behalf. 

Call for papers:

The Editor in Chief welcomes submissions.  Submissions of the following types are invited:

• Original research articles.
• Reviews: comprehensive, authoritative, descriptions of any subject within the journal's scope. They may cover basic science and clinical reviews, ethics, pro/con debates, and equipment reviews.
• Commentaries: focused and opinionated articles on any subject within the journal's scope. These articles are usually related to a contemporary issue.
• Hypotheses: articles that present an original hypothesis backed solely by previously published results rather than any new evidence. They should outline significant progress in thinking that would also be testable.
• Letters to the Editor: these can be either a re-analysis of a previously published article, or a response to such a re-analysis from the authors of the original publication.
• Methodology articles: these discuss a new experimental method, test or procedure. The article must describe a demonstrable advance on what is currently available. The method needs to have been well tested and ideally, but not necessarily, used in a way that proves its value.
• Short reports: brief reports of data from original research.
• Meeting reports: a report pertaining to activity at a meeting or conference Articles published in this journal are immediately available without delay upon publication and enjoy substantial visibility.
• Case reports: reports of clinical cases that can be educational, describe a diagnostic or therapeutic dilemma, suggest an association, or present an important adverse reaction. Case reports must meet appropriate ethical standards.

All submissions are subject to prompt, objective and fair peer review in compliance with our Fairness in Peer Review Policy.  Copyright in published articles remains with the author(s).  Authors are continually informed of the progress of their paper and our staff are friendly and responsive. 

One author recently wrote: "I would like to say that this is the most author-friendly editing process I have experienced in over 150 publications. Thank you most sincerely."

Criteria for publication: 

Publication is dependent on peer reviewers' judgement of papers.  Reviewers are asked to provide thoughtful and unbiased feedback to authors to ensure that the conclusions of papers are valid and manuscripts achieve reasonable standards of scholarliness and intelligibility. 

Previous work in the field must be acknowledged and papers should read without unreasonable difficulty.  Papers should fit comfortably within the scope of the journal.

Reviewers are asked to act in a fair, objective and constructive manner which maintains quality standards and helps authors to communicate their research.  They are instructed that in areas of genuinely novel research issues may be raised which cannot immediately be resolved and that absolutely rigorous validation of data may therefore not be possible. 

More information on the role of peer reviewers is available on the information for reviewers page.  Where authors consider that reviewers have made recommendations which are unreasonable, unobjective or ill-founded they may appeal them to the Editor in Chief or Associate Editor under our Fairness in Peer Review Policy.

What other authors have said:

Libertas Academica actively requests, receives and acts upon feedback from authors, readers and editorial boards.  Here's what some recent authors have said about us:

"Within a couple of days the reviewers had been procured and the manuscript was out."

"The communication between your staff and me has been terrific.  Whenever progress is made with the manuscript, I receive notice.  Quite honestly, I've never had such complete communication with a journal."

"LA is different, and hopefully represents a kind of scientific publication machinery that removes the hurdles from free flow of scientific thought."
