Retraction: Al-Salahi, R.A. et al. Cytotoxicity and anti-inflammatory activity of ethylsulfanyltriazoloquinazolines. Molecules 2013, 18, 1434-1446.

We have been made aware of the fact that a large proportion of the Introduction section and corresponding references of the title paper [1] had been copied verbatim from an earlier paper by Hamdy and Gamal-Eldeen [2], and further, during our investigation it has also come to light that most of the text in question had been lifted unchanged from an even earlier review paper by a different group [3]. The authors have been contacted, these facts confirmed, and Dr. Amira M. Gamal-Eldeen has been identified as the person responsible for contributing that part of the paper. As a member of the Committee on Publication Ethics (COPE), MPDI takes very seriously the responsibility to enforce a rigorous peer-review process together with strict ethical policies and standards to ensure the addition of high quality scientific works to the field of scholarly publication. In addition to an infringement of the Elsevier and American Association for Cancer Research copyright on the previous publications, this is also a clear violation of our policy to only publish new, previously unpublished material, so this paper is declared retracted and shall be marked accordingly for the scientific record. We cannot comment on any of the scientific data contained in the Molecules paper, which to the best of our knowledge is original. We would like to apologize to our readership on behalf of the Molecules editorial team for the fact this event went undetected during the peer-review and pre-publication processing of the paper and for any inconvenience caused by this event.

[Raw material synthesis and characterization of YVO4 birefringent crystal].

In this paper, synthesis of YOV4 birefringence crystal raw material in liquid phase was studied. Mostly, the effects of solution's pH values and some other synthesis conditions on purity and whiteness were discussed. Infra-red spectrometry, X-ray powder diffraction and UV spectrometry were used in the characterization of the raw material and single crystal, and in this way the best method of synthesis was defined. The result of the study indicates that the purity of the raw material had decisive effect on the crystal growth. Flawless crystal with the dimensions of phi 40 x 40 x 50 mm3 was grown by Czochralski (CZ) technique.

Publication of Controversial Papers in Life.

Life (ISSN 2075-1729, http://www.mdpi.com/journal/life/) is a new journal that deals with new and sometime difficult interdisciplinary matters. Consequently, the journal will occasionally be presented with submitted articles that are controversial and/or outside conventional scientific views. Some papers recently accepted for publication in Life have attracted significant attention. Moreover, members of the Editorial Board have objected to these papers; some have resigned, and others have questioned the scientific validity of the contributions. In response I want to first state some basic facts regarding all publications in this journal. All papers are peer-reviewed, although it is often difficult to obtain expert reviewers for some of the interdisciplinary topics covered by this journal. I feel obliged to stress that although we will strive to guarantee the scientific standard of the papers published in this journal, all the responsibility for the ideas contained in the published articles rests entirely on their authors. Discussions on previously published articles are welcome and I hope that, by fostering discussion and by keeping an open-minded attitude towards new ideas, the journal will spur progress in this little explored, difficult and very exciting area of knowledge.

Publisher's Note: Withdraw and Republication of "UV-Induced Radical Photo-Polymerization: A Smart Tool for Preparing Polymer Electrolyte Membranes for Energy Storage Devices".

It has been brought to the corresponding author's attention by the administration office that some of the authors present in this paper [1] are contradicting with the rules and regulation of some of the confidential industrial projects which have been signed with strict regulations. Now it has aroused as a big trouble and, consequently, to solve this problem all the authors have determined that it should be retracted. This decision has been taken purely for bureaucratic aspect. We apologize for any inconvenience this may cause.

Cells - An Open Access Journal of Cell Biology.

To expand the open access publishing project of our newly founded company MDPI [1,2] based in Basel, Switzerland, we are in the process of launching new journals. Based on our success in running journals that represent key areas in science and technology, such as Molecules [3], Sensors [4], Energies [5], Viruses [6], Pharmaceuticals [7], Cancers [8] and Toxins [9], we are launching a new journal entitled Cells. It is an open access journal combining cell biology, molecular biology and biophysics, toward an understanding of cell structure, function and interactions. [...].

Origin of Life and Birth of Life - An Open Access Journal.

Our publishing company MDPI (Multidisciplinary Digital Publishing Institute) planned to launch this journal Life (ISSN 2075-1729) since June 2009. Life science as a topic covers a very broad area. We decided to focus the scope of this new journal on the origin of life and the evolution of biosystems such as molecular evolution. Of course any fundamental theoretical topics and experimental discoveries in biology, biochemistry and biophysics will be welcomed also. [...].
