    Quantitative analysis of light elements using compact XRF spectrometers
    2021 - ZAMBONI, CIBELE B.; SILVA, DALTON G.N. da; TASSO, ORION G.; MEDEIROS, JOSE A.G. de; AZEVEDO, MARIA R.A. de
    The performance of two compact X-Ray Fluorescence (FRX) spectrometers consisting of Ag and Au X-ray mini-tubes associated with a Si Drift detector was checked for clinical finality. Using the Energy Dispersive X-Ray Fluorescence technique (FRXDE) specific light elements of clinical relevance (Ca, Cl, K and Fe) were determined in human whole blood samples without chemical digestion using direct and non-destructive analysis, in air atmosphere. A comparative study between Ag and Au targets data was carried out and the results are in good agreement.

    Análise de zinco em sangue de corredores de longa distancia
    2021 - SILVA, DALTON G.N. da; ZAMBONI, CIBELE B.; ALMEIDA, MATEUS R. de; MEDEIROS, JOSE A.G. de
    O objetivo deste estudo foi avaliar o zinco no sangue de atletas por metodologia de ativação de nêutrons. Os resultados mostraram deficiência de zinco para a maioria dos atletas. O estudo mostrou a eficácia da utilização desse procedimento analítico para sucessivas avaliações clínicas, durante o período de preparação das competições, fornecendo dados que auxiliam na elaboração de uma dieta balanceada, bem como contribuem para a proposição de novos protocolos de avaliação clínica.

    Progress and trends for radiation applications in clinical practice
    2019 - ZAMBONI, CIBELE B.; METAIRON, SABRINA; MEDEIROS, JOSE A.G. de; SILVA, DALTON G.N. da; TASSO, ORION G.
    In this study, we intend to optimize the use of equipment based on the X-Ray Fluorescence technology to perform ions dosage in body fluids. This procedure can be an efficient alternative for clinical diagnosis, mainly in underserved regions of Brazil with the deficit of medical care in the hospitals. In addition, this procedure has potential use when the biological material is scarce, case of the pediatric practice in newborns and premature infants (blood collection is the main cause of transfusions) as well as in Hemodialysis units which requires several biochemical tests (before and after dialysis).
