Abstract The use of X-ray fluorescence microanalysis was investigated to determine if it would allow further discrimination between samples of colorless acrylic and polyester fibers which were indistinguishable using brightfield, fluorescence and FTIR-microscopy. The aim was to determine if this technique could be successfully applied to single fibers of relatively fine titer and whether it would be beneficial to include it into the existing sequence of techniques used to compare colorless fibers. The extent of intra-garment variation and the possible effects of tape and mounting media residues on the elemental analysis were also investigated. The results confirmed the high value of fluorescence microscopy within the existing examination sequence and showed that single fiber analysis using X-ray fluorescence microanalysis is not only feasible, but improved the discriminating power between such colorless samples by about 50%.

It is well established that macromolecule oxidation, especially lipoprotein oxidation is a key and early event responsible for the loading of lipid into atherosclerotic foam cells and possibly many other features of atherogenesis. There have been many studies concerning protein oxidation and its contribution to the pathology. This study examined oxidized amino acid residues which may result from hydroxyl radical damage [Fu et al. 1995a. Free Rad Biol Med 19, 281-292; 1995b. Biochem. J. 311, 821-827; 1997. Biochem. J. in press] on intimal proteins isolated from normal human ateries and human atherosclerotic plaques. Normal iliac arteries (n = 6) were obtained from liver transplant donors and human plaques (n = 9) from patients undergoing carotid endarterectomy. Proteins were obtained from the intima samples after homogenization and delipidation and subquently subjected to acid-catalysed hydrolysis. Protein hydrolysates were analysed by several HPLC methods for the presence of oxidation products (characteristic of hydroxyl radical attack) of tyrosine (DOPA, dityrosine), phenylalnine (o- and m-tyrosine), valine (?-hydroxyvaline), and leucine (?-hydoxyleucine). Results are expressed as mmol oxidized amino acid/mol parent amino acid and are summarized in the table below. It shows that all of the oxidized amino acids measured are elevated in the plaque samples compared to those in the normal controls, suggesting that hydroxyl radicals may be an important factor for atherogenesis

To evaluate the occurrence of background and crime-related fibre groups on car seats under controlled conditions, the usage of 22 selected car seats was recorded over a one-month period before fibre transfer experiments were performed using a known donor
