Journal ArticleDOI
Antifungal Pisum sativum defensin 1 interacts with Neurospora crassa cyclin F related to the cell cycle
Denise S. Lobo,Iuri B Pereira,Lucianne Fragel-Madeira,Luciano Neves de Medeiros,Luiz M Cabral,Jane Faria,Maria Bellio,Reinaldo Calixto de Campos,Rafael Linden,Eleonora Kurtenbach +9 more
TL;DR: The results demonstrated that the plant defensin Psd1 regulates interkinetic nuclear migration in retinal neuroblasts and directed cell cycle impairment and caused conidia to undergo endoreduplication in neonatal rats.
Journal ArticleDOI
The determination of trace elements in crude oil and its heavy fractions by atomic spectrometry
Christiane B. Duyck,Norbert Miekeley,Carmem Lúcia P. da Silveira,Ricardo Q. Aucélio,Reinaldo Calixto de Campos,Patricia Grinberg,Geisamanda Pedrini Brandão +6 more
TL;DR: A literature review on the determination of trace elements in crude oil and heavy molecular mass fractions (saturates, aromatics, resins and asphaltenes) by ICP-MS, ICP OES and AAS is presented in this paper.
Journal ArticleDOI
Chemical Vapor Generation: Atomic Absorption by Ag, Au, Cu, and Zn Following Reduction of Aquo Ions with Sodium Tetrahydroborate(III)
TL;DR: A univariate approach was used to achieve optimized conditions and derive analytical figures of merit and loss of analyte during transport to the QTA was minimized through use of the minimum length of narrow-bore Teflon transfer line possible.
Journal ArticleDOI
The determination of trace metals in lubricating oils by atomic spectrometry
Ricardo Q. Aucélio,Roseli M. de Souza,Reinaldo Calixto de Campos,Norbert Miekeley,Carmem Lúcia P. da Silveira +4 more
TL;DR: In this paper, the importance of trace metal analysis for technical diagnostics and specific sample characteristics related to the analyte form (metallo-organic and metal particles) is discussed, problems related to sample pre-treatment for appropriate sample introduction and calibration are addressed as well as the strategies to overcome them.
Journal ArticleDOI
Cadmium uptake by hydroxyapatite synthesized in different conditions and submitted to thermal treatment.
Nilce C.C. da Rocha,Reinaldo Calixto de Campos,Alexandre Malta Rossi,Elizabeth Lima Moreira,Ademarlaudo Do F. Barbosa,Gustavo Torres Moure +5 more
TL;DR: It has been determined that the variation on the hydroxyapatite sorption capacity is neither related to sample solubility nor to hydroxyAPatite Ca/P molar ratio, and the influence of sample thermal treatment on Cd2+ sorption efficiency is studied.
