  • The xeroderma pigmentosum complementation group C gene (XPC) has been identified as important for repairing UV-related DNA damage. Some subtle changes in this gene may impair repair efficiency and influence susceptibility to human cancers, including skin cancer. Two polymorphisms in XPC, 939A>C (rs2228001) and 499C>T (rs2228000), are considered to have possible associations with the risk of skin cancer, but the reported results have been inconsistent. Here we performed a meta-analysis of the available evidence regarding the relationship between these two polymorphisms and the risk of skin cancer. All relevant studies were searched using PubMed, Embase and Web of Science before February 2012. A total of 8 case-control studies were included in this analysis, and no convincing associations between the two polymorphisms and risk of skin cancer were observed in any of the genetic models. Stratified analyses by skin cancer type also did not detect significant associations in any subgroup. This meta-analysis suggested that the XPC 939A>C and 499C>T polymorphisms may have little involvement in susceptibility to skin cancer.

  • The skin friction of a pile foundation is important and essential for its design and analysis. More attention has been given to the softening behaviour of skin friction of a pile. In this study, to investigate the load-transfer mechanism in such a case, an analytical solution using a nonlinear softening model was derived. Subsequently, a load test on the pile was performed to verify the newly developed analytical solution. The comparison between the analytical solution and test results showed a good agreement in terms of the axial force of the pile and the stress-strain relationship of the pile-soil interface. The softening behaviour of the skin friction can be simulated well when the pile is subjected to large loads; however, such behaviour is generally ignored by most existing analytical solutions. Finally, the effects of the initial shear modulus and the ratio of the residual skin friction to peak skin friction on the load-settlement curve of a pile were investigated by a parametric analysis.

  • In this paper, we proposed and developed a new portable skin elasticity measuring device based on the indentation method using piezoelectric effect. The proposed device is designed to minimize the uncertainty caused by the layer structure of the skin when measuring the elasticity of the skin. And, we developed a piezoelectric-based thin-film pressure sensor that can measure quantitatively and quickly during repeated measurement as a device sensor. To confirm the effectiveness of the proposed measuring device, it was compared with the experimental results of the conventional measuring devices under the same experimental conditions, and statistical correlation analysis was performed between the experimental data of the proposed measuring device and the experimental data of the conventional measuring devices. As a result of the correlation analysis, it was confirmed that the proposed measuring device had a high correlation with the conventional measuring devices. Therefore, it was confirmed that the proposed skin elasticity measuring device was effective.

  • Background Diabetes is characterized by chronic hyperglycemia, which can increase reactive oxygen species (ROS) production by the mitochondrial electron transport chain. The formation of ROS induces oxidative stress and activates oxidative damage-inducing genes in cells. No research has been published on oxidative damage-related extracellular superoxide dismutase (EC-SOD) protein levels in human diabetic skin. We investigated the expression of EC-SOD in diabetic skin compared with normal skin tissue in vivo. Methods The expression of EC-SOD protein was evaluated by western blotting in 6 diabetic skin tissue samples and 6 normal skin samples. Immunohistochemical staining was also carried out to confirm the EC-SOD expression level in the 6 diabetic skin tissue samples. Results The western blotting showed significantly lower EC-SOD protein expression in the diabetic skin tissue than in the normal tissue. Immunohistochemical examination of EC-SOD protein expression supported the western blotting analysis. Conclusions Diabetic skin tissues express a relatively small amount of EC-SOD protein and may not be protected against oxidative stress. We believe that EC-SOD is related to the altered metabolic state in diabetic skin, which elevates ROS production.

  • The purpose of this study is to predict skincare behavior from the perspective of theories about planned behaviors and a systematic structure for identifying influences on human behavior; Consequently, this study attempted to undertake a concrete analysis of influences on skin care behavior. The results showed that: an attempt was made to analyze structural equation modeling as to whether or not to apply Ajzen's theory of planned behavior to skin care behavior. This study found the possibility that the theory of planned behavior might be applicabled to the research model composed of skin care attitude, the norms of skin care, behavioral control on skin care, behavioral intentions of skin care, and skin care behavior at the appropriate level in their entirety. This study found that external control factors of skin care behavior had the highest effect on skin care behavior among other factors.
