Idiopathic interstitial pneumonia (IIP) is a progressive fibrosing interstitial pneumonia of unknown etiology with a poor prognosis. The aim of this study is to prove the occurrence of particle deposition and particle-induced tissue damage in IIP by examining proapoptotic Fas expression with in-air microparticle induced X-ray emission (in-air micro-PIXE) analysis. A total of 21 patients were en...

Ancient potteries found at Ban Muang Bua, located in northeastern Thailand, associate with Thung Kula Ronghai culture. Most of them are products used daily life and grave goods. The potsherds were examined using techniques based on X-ray spectroscopy. Elemental composition morphology analyzed proton-induced emission spectroscopy (PIXE) scanning electron microscopy coupled energy-dispersive (SEM...

in this study, 27 achaemenid coins, 62 parthian coins, 66 sassanid coins, have been analyzed. the achaemenid coins as well as 20 parthian coins belong to the national museum of iran and the other 42 parthian coins are kept in tamashagah-e pool museum. sasanid coins belong to private collectors. using pixe analysis, the element concentrations of the coins were measured. by using statistical anal...

Commercial grapefruit seed extracts (GSE) were extracted with chloroform. The solvent was evaporated, and the resulting solid was subsequently analyzed by high-performance liquid chromatography, electrospray ionization mass spectrometry, nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis (by proton-induced X-ray emission [PIXE] analysis). The main constituent was identified a...

For several years, the specific features of PIXE and PIGE have made them very attractive in the field of archaeometry. Among them, non-destructivity is one of the most important. The possibility of working under atmospheric pressure is also important because of the very different shapes and sizes of the artefacts concerned. However, these ion beam techniques suffer from the same disadvantage: t...

PURPOSE To determine whether iron homeostasis disorder accompanies retinal degeneration in Royal College of Surgeons (RCS) rats. METHODS The presence of iron was revealed directly by proton-induced X-ray emission (PIXE) and indirectly by electron microscopy (EM). Ferritin, transferrin (Tf), and transferrin receptor (Tf-R) were localized by immunohistochemistry. Ferritin and Tf proteins were a...

Abstract To extract information on elemental components and PM characteristics from smoke number (SN) filter paper, we were performed analysis by micro-PIXE. As a result of the SN filter, composition jet engine exhaust was obtained. Regarding have been collected for each difference in thrust various aircraft engines at turbine test cells around world. By periodically analyzing such it is possib...
