Mutations in the filaggrin （FLG） gene, the gene coding profilaggrin/filaggrin, have a great impact on the epidermal barrier function and are an important predisposing factor for AD.

Effects of the aqueous components, pH, con-centration of NaCl, and volume ratios of oil-to-water on the desulfurization activity of gram-negative desulfurizing bac-terium, Pseudomonas delafieldii R-8, were investigate...Effects of the aqueous components, pH, con-centration of NaCl, and volume ratios of oil-to-water on the desulfurization activity of gram-negative desulfurizing bac-terium, Pseudomonas delafieldii R-8, were investigated. R-8 showed high desulfurization activity even with a concentra-tion of NaCl up to 60 g·L-1 or high content of dodecane over 83%. The addition of NADH could increase the desul-furization activity of the whole cells. The desulfurization of DBT could be proceeded in the presence of hydrocarbons with the carbon length ranging from 6 to 16. Among them, the largest specific desulfurization activity was shown in dodecane, the value of which was 1.96 mg·g-1·h-1 similar to that of R. erythropolis IGTS8.展开更多
