Steatosis, i.e., the accumulation of fat in hepatocytes, plays an important role in the progression of non-alcoholic fatty liver disease (NAFLD). It has been shown that STAT3 activation is involved in a decrease of lipid accumulation while C/EBP/ is correlated with an increase of fat content and steatosis. It is known that STAT3 and C/EBP/ are activated by IL-6 and that IL-6 signalling is also affected...
The need for a sensitive method of the non-destructive evaluation of skin layer properties is highly desirable in a number of medical applications. The use of laser-generated surface acoustic waves (SAW) for the characterisation of multi-layered materials is widely used in industrial applications. In this paper we present research expanding this principle for the use of generated SAW for the characterisation...
A finite element (FE) simulation of the thermoelastic laser generated surface waves in a 3-layered model of human skin is presented. Commercial finite element code ANSYS is used to study the effects of changing laser wavelength and hence the optical absorption has on the generated surface waves. The FE model consists of a thermal analysis with a volumetric heat generation boundary condition to simulate...
