Modulation of zinc levels and tissue properties: Essentia Biosystems discloses the modulation of zinc levels to improve tissue properties. Methods of altering the properties of tissues were explored by modifying the amount of zinc, which may be in the form of zinc ions, through the use of topical compositions containing one or more zinc-containing components such as salts and/or other zinc compounds or in complexes, particularly zinc acetate. By altering the zinc levels, researchers found they were able to increase or decrease fatty tissue, increase or decrease epidermal thickness, increase elastin content, and prevent or treat gum regression or atrophy.

Trademarks
By: Larry Plonsker, Chemical Network Associates
Technology licensing is a large and important business activity for those companies and institutions that generate technology. In this column, we always feature technologies available for license, mainly from universities, but many companies, large and small, utilize technology licensing to generate significant income. What is surprising is that technology licensing is not the major segment of the licensing business. According to an article by Weston Anso1 in a Trademark World article, “the corporate trademark/brand licensing segment is now the largest segment of the licensing industry and has had the greatest and most consistent growth over the last decade.” We are all familiar with trademarks as we see them everywhere we are exposed to advertising or branded products. This article will try to provide an understanding of what constitutes a trademark, how you get them and how to value and use them.

Evaluating the maturity of cornified envelopes: Hirao has published a review on the significance of cornified envelopes in barrier function of the stratum corneum. Cornified envelopes (CE), which are rigid and insoluble structures surrounding the corneocytes, are assembled by crosslinking of several precursor proteins by transglutaminases. The CE provide the basis for barrier function of the stratum corneum.

Polypodium leucotomos and Other Topics
By: Charles Fox, Independent Consultant
Polypodium leucotomos extract to decrease UV-induced damage: Exposure of human skin to sunlight containing UVA and UVB radiation exposes the skin to deleterious effects such as sunburn, immune suppression, pigmentary changes, photoaging and skin cancer. The mechanism of such cutaneous damage induction is complex, but can be broadly divided into direct oxygen-dependent damage through absorption of photons, and oxidative damage caused by formation of free radicals and reactive oxygen species. This is why antioxidants have been increasingly studied as inhibitors or quenchers of UV-induced cutaneous damage.
