The Association Of Skin Cancer Prevention Knowledge, Sun-Protective Attitudes, And Sun-Protective Behaviors In A Navy Population, Rachel Newnam, Uyen Le-Jenkins, Carolyn Rutledge, Craig Cunningham

Nursing Faculty Publications

Introduction: U.S. Navy service members are primarily between the ages of 18 and 30 years and often required to be outside for extended periods of time in geographical locations with increased and often unfamiliar ultraviolet indexes that collectively increase their risk for skin cancer. Skin cancer is the country's most common form of cancer, yet there is a paucity of skin cancer prevention literature, especially within the U.S. Navy. The purpose of this study was to describe skin cancer risk and skin cancer prevention "cues-to-action" and to determine if skin cancer prevention knowledge was associated with sun-protective attitudes (e.g., prevention …

Potential Chemical Risks From Tattoos And Their Relevance To Military Health Policy In The United States, James D. Blando, Blas A. Guigni

Community & Environmental Health Faculty Publications

We summarize and consolidate disparate sources of information about the practice of tattooing and its potential implications for military population health and policy. Each branch of the United States military has policies about tattoos for service members, but these have varied over time and do not cover health protection. The number of veterans receiving disability payments and the cost of those payments has been rising over time; the broad category of skin conditions accounts for 11% of disability claims. Any additional factor, such as tattoos that may increase the occurrence of adverse skin reactions, can substantially impact veteran benefit expenses …

In Vitro And In Vivo Correlation Of Skin And Cellular Responses To Nucleic Acid Delivery, M. Bosnjak, K. Znidar, A. Sales Conniff, T. Jesenko, B. Markelc, Nina Semenova, J. Tur, K. Kohena, S. Kranjc Brezar, L. Heller, M. Cemazar

Skin, the largest organ in the body, provides a passive physical barrier against infection and contains elements of the innate and adaptive immune systems. Skin consists of various cells, including keratinocytes, fibroblasts, endothelial cells and immune cells. This diversity of cell types could be important to gene therapies because DNA transfection could elicit different responses in different cell types. Previously, we observed the upregulation and activation of cytosolic DNA sensing pathways in several non-tumor and tumor cell types as well in tumors after the electroporation (electrotransfer) of plasmid DNA (pDNA). Based on this research and the innate immunogenicity of …

Monopolar Gene Electrotransfer Enhances Plasmid Dna Delivery To Skin, Anna Bulysheva, Loree Heller, Michael Francis, Frency Varghese, Carly Boye, Richard Heller

Electrical & Computer Engineering Faculty Publications

A novel monopolar electroporation system and methodologies were developed for in vivo electroporation intended for potential clinical applications such as gene therapy. We hypothesized that an asymmetric anode/cathode electrode applicator geometry could produce favorable electric fields for electroporation, without the typical drawback associated with traditional needle and parallel plate geometries. Three monopolar electrode applicator prototypes were built and tested for gene delivery of reporter genes to the skin in a guinea pig model. Gene expression was evaluated in terms of kinetics over time and expression distribution within the treatment site. Different pulsing parameters, including pulse amplitude, pulse duration, and pulse …

In Vitro And In Vivio Evaluation Of A Moisture Treatment Cream Containing Three Critical Elements Of Natural Skin Moisturization, David H. Mcdaniel, Jeffrey S. Dover, Mitchell Wortzman, Diane B. Nelson

Biological Sciences Faculty Publications

Objectives

To evaluate skin barrier and hydration effects of a new rebalancing moisture treatment (TRMT) and to assess efficacy and tolerability in subjects with photodamaged skin.

Methods

In an epidermal skin model, tissues (n = 5/group) were topically treated with 25 µL of TRMT, 25 µL of a market‐leading moisturizer (MLM), or untreated for 60 minutes. Hydration was measured at 0, 15, and 30 minutes. Tissues were harvested for gene expression analysis of markers associated with skin barrier and hydration: Claudin (CLD), Aquaporin (AQP), Hyaluronic Acid Syntheses (HAS), and Hyaluronidase (HYAL). A clinical study evaluated twice‐daily application of TRMT, assessing …

Cutaneous Blood Flow In Type 2 Diabetic Individuals After An Acute Bout Of Maximal Exercise, Sheri R. Colberg, Henri K. Parson, D. Robb Holton, Tanja Nunnold, Aaron I. Vinik

Human Movement Sciences & Special Education Faculty Publications

OBJECTIVE - We previously demonstrated a positive association between chronic aerobic exercise and dorsal foot skin blood flow during local heating in type 2 diabetic individuals. Thus, we hypothesized that a prior acute bout of maximal exercise would also have positive effects on postexercise blood now.

RESEARCH DESIGN AND METHODS - Subjects consisted of 32 individuals with type 2 diabetes and 26 nondiabetic control subjects further subdivided based on their physical activity status diabetic exerciser (DE), diabetic sedentary (DS), control exerciser (CE), or control sedentary. Dorsal foot cutaneous blood flow was measured noninvasively by continuous laser-Doppler assessment at baseline and …
