I am pleased to present in this issue the first of a series of specially invited review articles that seek to present the state of the art of their chosen biomechanical topic. The inaugural article is entitled “The specific growth rates of tissues: A review and a reevaluation” by Dr. Stephen C. Cowin of the Department of Biomedical Engineering, CUNY. In this article, Dr. Cowin presents a brief history of efforts to mathematically model the growth of tissues. He then continues to present a case for the reevaluation of current approaches and several novel ideas. It is one of the most thought-provoking, expansive articles I have read in recent years on the very exciting topic of tissue growth and remodeling. I hope you all enjoy it as much as I have.

We are currently planning several more of these articles for this coming year. These articles receive absolute top priority for publication, are of extended length (equivalent to two to three standard manuscripts), are rapidly reviewed, with the review process handled personally by the editor, with all page charges waived, and are to be published in the next available issue. If you are interested in contributing a review article, please contact me directly with a title, abstract, and estimated completion date.

Yours sincerely,Michael S. Sacks, Ph.D.EditorJohn A. Swanson ChairDepartment of Bioengineering, University of Pittsburghe-mail: msacks@pitt.edu
