Paraffin melting is widely applied to the fields of PCM energy storage, gathering and transportation pipe-line paraffin removal, etc. Natural-convection main heat transfer mode during melting, Rayleigh number an important factor affecting change natural-convection intensity. Nusselt variation can reflect influence on transfer. The conventional hot wall surface reflects only convective intensity...
A problem associated with use of the polymerase chain reaction to amplify specific DNA fragments from formalin fixed, paraffin wax embedded tissues is the not infrequent failure of amplification. One possible reason for this could be the presence of inhibitor(s), which interfere with the activity of the reaction. It has been shown that such inhibitor(s) exist when amplifying the human fl globin...
BACKGROUND The skin represents a potent barrier to the environment, which can be enhanced by the topical application of skin care products, such as oil and oil-based formulations by moisturizing the skin. METHODS The aim of this study was the investigation of the penetration behaviour of four vegetable oils and of paraffin oil into the stratum corneum by laser scanning microscopy. In addition...
AIMS To determine, by in situ immunohistochemistry, whether ovarian carcinomas have increased expression of DNA topoisomerase I. METHODS Paraffin wax blocks obtained from 15 samples of normal human tissues and from 14 cases of ovarian cancer were cut on to glass slides and immunohistochemically stained for topoisomerase I. The primary antibody was a mouse monoclonal that recognises topoisomer...
