Light propagation in biological tissue.

J Opt Soc Am A Opt Image Sci Vis 20(1):92-8 (2003) PMID 12542322

Biological tissue scatters light mainly in the forward direction where the scattering phase function has a narrow peak. This peak makes it difficult to solve the radiative transport equation. However, it is just for forward-peaked scattering that the Fokker-Planck equation provides a good approximation, and it is easier to solve than the transport equation. Furthermore, the modification of the Fokker-Planck equation by Leakeas and Larsen provides an even better approximation and is also easier to solve. We demonstrate the accuracy of these two approximations by solving the problem of reflection and transmission of a plane wave normally incident on a slab composed of a uniform scattering medium.

    We have revealed that HMGB1 two paralogs are broadly retained from fish onwards in the phylogeny. However, their spatial-temporal expression and effects, as shown in lowest amniote gecko, were tightly controlled in order that limited inflammation was produced in spontaneous regeneration. Gecko HMGB1...

    We investigated if the analysis of FFPE tissue lysates with RPPA would result in biological meaningful data in two independent studies. In the first study with breast cancer samples we assessed whether human epidermal growth factor receptor 2 (HER2) score based on immunohistochemistry (IHC) can be r...
