Stratum corneum (SC), the outermost layer of human skin, acts as an intelligent physicochemical interface between the inside and the outside of our body. To make clear the relationship between structure and physical barrier properties of SC, we developed a method that enables us to simultaneously acquire X-ray diffraction (XD) patterns and transepidermal water loss (TEWL) values using a spread SC sheet isolated from human skin. The synchrotron X-ray was incident on the SC sheet surface at an ang...

Two genes, TK1280 and TK2287, encode orthologous transcription factor B proteins (TFB1 and TFB2, respectively) in the hyperthermophilic archaeon Thermococcus kodakarensis. The functional difference between their TFBs remains unknown. While TFB1 and TFB2 displayed equivalent thermostability, mRNA levels of tfb1 at 93 °C were eightfold higher than those at 60 or 85 °C, and were 4- to 10-fold greater than those of tfb2 at all temperatures. This suggests that TFB1 is the abundant TFB in T. kodakaren...

Abstract We have improved the selected area electron diffraction method to analyze the dynamic structural change in a single corneocyte cell non-invasively stripped off from human skin surface. The improved method made it possible to obtain reliable diffraction images to trace the structural change in the intercellular lipid layers on a single corneocyte cell during heating from 24 °C to 100 °C. Comparison of the results with those of synchrotron X-ray diffraction experiments on human stratum co...

Abstract Human skin stratum corneum (SC) structures were investigated by electron diffraction (ED) with a very low-flux electron beam with the help of high-sensitivity detectors, the imaging plate and the CCD camera. This low-flux electron diffraction (LFED) method made it possible to minimize the unfavorable effect of electron beam damage and to give a reliable diffraction pattern from a small selected area (0.2 μm 2 ) on a corneocyte. Dependence of the 2-dimensional ED pattern on the size of t...
