Expression of concern--Mavoungou E. Interactions between natural killer cells, cortisol and prolactin in malaria during pregnancy. Clin Med Res 2006;4:33-41.

The editors of Clinical Medicine & Research were notified by a third party that the article published in 2006 by Elie Mavoungou1 contains large amounts of text that appear to be taken verbatim from, and without attribution to, an article by Jeffrey S. Miller2 previously published in Experimental Hematology. Neither Clinical Medicine & Research nor Experimental Hematology has record of a request by Dr. Mavoungou to reproduce the information from Dr. Miller’s article. 
 
The editors of Clinical Medicine & Research have attempted to contact Dr. Mavoungou for an explanation, but have not received a response. At this time, we express our concern regarding the duplication of information without proper copyright permission from Experimental Hematology. We are consulting the Committee on Publication Ethics (COPE) Guidelines for Good Publication Practice3 for advice on handling this situation. We will keep our readers informed of additional information received and decisions made regarding this article.
