Microwave energy (MWE) as a method of rapid tissue processing is gaining increasing support as an alternative to routine chemical processing in diagnostic laboratory environments. Chemical fixatives and conventional fixation times used for standardized preservation of tissues can result in serious alterations in morphology as a consequence of solubilization and conformational changes of proteins and lipids. These untoward changes typically result in compromised antigenicity of many tissue proteins. With MWE processing, tissue antigens can be distinctly better preserved, antigen retrieval made more replicate and histochemical and immunochemical reactions made ultrafast. The present study had two objectives: to compare MWE processed skin to conventionally processed skin for ultrastructural integrity; to compare MWE expression of antigenicity of selected skin proteins which are usually sensitive to conventional chemical processing. Skin proteins selected were bullous pemphigoid antigen (BPA) and laminin.

ABSTRACTPrevious research work in the area of microwave heating for low temperature thermal desorption of contaminates has led to a novel method of delivering heat energy to contaminated materials (soils) that have poor electrical characteristics for the absorption of microwaves. This method involves the use of a heating facilitator. The facilitator, which in this case is a ferromagnetic material (magnetite), is admixed with the soil or sludge to be treated. When exposed to microwave energy, the facilitator preferentially absorbs the energy and transfers heat to the contaminated matrix. Using this method, it has been possible to achieve temperatures in excess of 900 °C (1650 °F) in test soils. At these temperatures, even the highest molecular weight hydrocarbon contaminants are compelled to desorb from the soil.The advantage of using magnetite is that it can be separated by conventional separation methods for recycle and reuse. The technology has implications of being useful in several chemical processing operations.

The purpose of this study was to examine the external structure of four human hair shaft samples with the scanning Electron Microscope (SEM) and to obtain information regarding the chemical composition of hair by using the attached x ray microanalysis unit.The hair samples were obtained from two female subjects. Sample A was taken from a black female and had not undergone any type of chemical processing. Sample B, C, D were taken from a white female, and were natural, processed, and unpigmented, i.e. “gray”, respectively. Sample C had been bleached, tinted, and chemically altered using a permanent wave technique.
