Anti-Aging and Lightening Effects of Au-Decorated Zeolite-Based Biocompatible Nanocomposites in Epidermal Delivery Systems.

The main challenges in developing zeolites as cosmetic drug delivery systems are their cytotoxicities and the formation of drug-loading pore structures. In this study, Au-decorated zeolite nanocomposites were synthesized as an epidermal delivery system. Thus, 50 nm-sized Au nanoparticles were successfully deposited on zeolite 13X (super cage (α) and sodalite (β) cage structures) using the Turkevich method.

Public information officers' and journalists' perceived barriers to providing quality health information.

Given the increase in the volume of health and medical news over the past few years, the expanding population of journalists committed to feeding the public's voracious appetite for such information, and the important role of government public health organizations in producing and disseminating public health information, it is surprising that little research exists that explores the relationships among public health entities and health journalists. This article describes and analyzes similarities and differences in perceptions between journalists and information officers in public health agencies on a number of issues to reveal how public information officers and health journalists can work to build a local public health agenda free from the burden of unnecessary or inconsistent barriers. This study reports findings from a study with a 3-stage pretest and 90 interviews with state and local public health information officers and the health journalists who cover public health beats across the United States.
