The wear mechanism was tentatively discussed according to the morphologies and chemical compositions of the debris examined by transmission electron microscope and X-ray photoelectron spectroscopy.
The concept that opsonization may differentially regulate uptake of different compositions of wear debris is also supported by observations that the spectra of adherent human serum proteins demonstrate a level of particle specificity [ 33].
Additionally, in the MoM THA, black, irregular metallic particles were seen along with green corrosion products within the macrophages, suggesting different origins and/or compositions of metallic debris being produced in this implant type.
The main mineral composition of the rock debris is quartz and feldspar.
The image of Cassiopeia A contains clues to the temperature and composition of the hot debris from the explosion; thanks to Chandra's large, high-quality x-ray mirrors, it shows much more detail than earlier x-ray photos of the supernova remnant, made by satellites like the U.S.-German ROSAT.
Marine systems are sinks for pre- and post-consumer plastic and the multifaceted negative impacts of plastic pollution on wildlife (reviewed in Cole et al., 2011; Derraik, 2002; Oehlmann et al., 2009) as well as several aspects of debris composition, distribution and abundance have been described here (reviewed in Ryan et al., 2009).
Results of the friction coefficients values, the wear volumes, debris composition of the heat-exposed and -unexposed samples are compared.
All orthopedic implants, regardless of their composition, shed debris as they wear.
When the infection recedes due to removal of pathogens and cellular debris, the composition of the local environment will change facilitating differentiation of monocytes to anti-inflammatory/pro-angiogenic macrophages.
