Artigo IPEN-doc 26475 Multielemental analyses of Lonomia obliqua (Lepidoptera, Saturniidae) caterpillar using EDXRF and INAA techniques2019 - ZAMBONI, C.B.; GIOVANNI, D.N.S.; SALVADOR, V.L.R.; SATO, I.M.; MENDONÇA, R.Z.; WEN, F.H.; SIMONS, M.S.In this study, multielemental analysis of Lonomia obliqua (Lepidoptera, Saturniidae) caterpillar was performed using energy dispersive X‐ray fluorescence and instrumental neutron activation analysis techniques. This caterpillar is poisonous and has the ability to cause fatal hemorrhagic effects in humans after contact. The need of this study is related to morphological changes (mainly size and color) observed in some caterpillars used for preparation of antilonomic serum (antivenom). The samples were classified as healthy (caterpillars of control) and unhealthy (caterpillars visibly modified). The XRF measurements were performed in an energy dispersive X‐ray fluorescence spectrometer and the instrumental neutron activation analysis using the IEAR1 nuclear reactor at IPEN. The results show significant differences for several elements (mainly, P, Cl, Ca, Ti, Mn, Fe, Ni, and Zn) in unhealthy caterpillars that can affect the development of this species as well as the quality and yield of the antivenom. Furthermore, its elemental characterization contributes for the understanding the potential pharmacological (procoagulant and antithrombotic) in the prevention of life‐threatening blood clots.Artigo IPEN-doc 23535 Determination of Cu, Cr, and As in preserved wood (Eucalyptus sp.) using x-ray fluorescent spectrometry techniques2016 - PEREIRA JUNIOR, SERGIO M.; MAIHARA, VERA A.; MOREIRA, EDSON G.; SALVADOR, VERA L.R.; SATO, IVONE M.Energy dispersive (EDXRF) and Portable (PXRF) X-ray fluorescence techniques are proposed for wood treatment control process and wood waste assortment. In this study, different retentions of chromated copper arsenate preservative were applied to Eucalyptus sp. sapwood samples. Cu, Cr and As were determined by XRF techniques in treated sapwood massive blocks and treated sapwood sawdust samples were analyzed by FAAS spectrometry (Flame Atomic Absorption) and INAA (Instrumental Neutron Activation Analysis). Cu, Cr and As mean values, obtained by FAASS and INAA, showed to be statically equal; however, XRF analysis showed considerable deviations, presenting the absorption and the enhancement effects in analytical lines.Artigo IPEN-doc 21759 Comparative study of inorganic elements determined in whole blood from Dmdsup(mdx)/J mice strain by EDXRF and NAA analytical techniques2016 - REDIGOLO, M.M.; SATO, I.M.; METAIRON, S.; ZAMBONI, C.B.Resumo IPEN-doc 20753 Comparative study of inorganic elements determination in whole blood from Dmdsup(mdx)/J mice strain by EDXRF and NAA analytical techniques2014 - REDIGOLO, MARCELO M.; SATO, IVONE M.; METAIRON, SABRINA; ZAMBONI, CIBELE B.Resumo IPEN-doc 10410 Preparation of in-house bovine liver reference material2005 - MAIHARA, V.A.; FAVARO, D.I.T.; VASCONCELLOS, M.B.A.; SATO, I.M.; SALVADOR, V.L.R.; MANTOVANI, D.; MORGANO, M.A.; MAIO, F.D.; KIRA, C.S.; CANTAGALLO, M.I.; SISTI, C.; KEIKO, E.S.; SHIHOMATSU, H.M.Resumo IPEN-doc 10328 Estimated daily intake of mineral and trace elements in brazilian worker duplicate diet samples2005 - MAIHARA, V.A.; FAVARO, D.I.T.; VASCONCELLOS, M.B.A.; SATO, I.M.; SALVADOR, V.L.R.; MONTOVANI, D.; MORGANO, M.A.; KIRA, C.S.; MAIO, F.D.Resumo IPEN-doc 16214 Inorganic elements determination in laboratory animals whole blood samples EDXRF technique2010 - REDIGOLO, M.M.; AGUIAR, R.; ZAMBONI, C.B.; SALVADOR, V.L.R.; SATO, I.M.Resumo IPEN-doc 08531 Assessment of some mineral and trace elements in workers' diets from Sao Paulo, Brazil, by neutron activation analysis and X-ray fluorescence techniques2002 - MAIHARA, V.A.; FAVARO, D.I.T.; SATO, I.M.; SALVADOR, V.L.R.; RODRIGUEZ, M.I.; VASCONCELLOS, M.B.A.Resumo IPEN-doc 19789 Comparative study of inorganic elements determination in whole blood from DmDsup(mdx)/J mice strain by EDXRF and NAA analytical techniques2013 - REDIGOLO, M.M.; SATO, I.M.; METAIRON, S.; ZAMBONI, C.B.Resumo IPEN-doc 19787 Investigation of inorganic elements in saliva from Amblyomma cajannense species from Brazil by the EDXRF technique2013 - SATO, IVONE M.; ZAMBONI, CIBELE B.; OLIVEIRA, DANIELLA G.L.; CHUDZINSKI-TAVASSI, ANA M.; SIMONS, SIMONE M.
