https://www.selleckchem.com/products/az20.html Calcium deposition within the atherosclerotic plaques is the precursor of cardiovascular complications. Therefore, determination of levels of minerals and trace elements in blood plays an important role in assigning the stage of atherosclerosis. In this study, determination of mineral and trace element levels in atherosclerotic patients is aimed. Mineral and trace element levels within serum samples of 12 atherosclerotic patients were evaluated by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and phosphorous (P), iron (Fe), magnesium (Mg) and calcium (Ca) levels were examined. Human carotid atherosclerotic plaque samples were previously screened by Scanning Acoustic Microscopy (SAM) and sound speed maps of the plaques showed higher sound speed values in the calcified regions, when compared to collagen-rich regions, indicating accumulation of calcium. Element analysis also showed increased Ca levels within serum samples. Therefore, it can be concluded that Ca deposition can be examined by ICP-OES and SAM, indicating that these techniques are confirmatory and may be combined to characterize atherosclerosis in the future.Ionization chamber dosimetry is predominantly used for determination of the absorbed dose to water in 60Co and high-energy radiotherapy photon beams. The most widespread ionization chambers employed for absolute or reference dose determinations in reference conditions are the Farmer-type cylindrical ionization chambers. The Farmer-type ionization chambers have a variety of constructions and materials and their responses vary in the radiation beam. Clinical accelerators, in addition to conventional photon beams with flattening-filter, can also deliver flattening-filter-free (FFF) photon beams. The responses of five different Farmer-type cylindrical ionization chambers were experimentally examined with reference to absorbed dose determination in reference conditions when using the Intern
