Journal ArticleDOI
Study of thioureas derivatives synthesized from a green route as corrosion inhibitors for mild steel in HCl solution
Vanessa Vasconcelos Torres,V.A. Rayol,Mariana Gonzalez Martins de Magalhães,Gil Mendes Viana,Lucia C. S. Aguiar,Sergio Machado,Hugo Orofino,Eliane D'Elia +7 more
TL;DR: In this article, the behavior of 1,3-dibenzylthiourea (DBTU) and 1-benzyl-3-diisopropylthIourea was investigated as carbon steel corrosion inhibitors in HCl solution by weight loss measurements, potentiodynamic polarization curves, electrochemical impedance and scanning electron microscopy analysis.
Journal ArticleDOI
Electronic Structure and Spectro-Structural Correlations of FeIIIZnII Biomimetics for Purple Acid Phosphatases: Relevance to DNA Cleavage and Cytotoxic Activity
Rosely A. Peralta,Adailton J. Bortoluzzi,Bernardo de Souza,Rafael Jovito,Fernando R. Xavier,Ricardo Alexandre Alves de Couto,Annelise Casellato,Faruk Nome,Andrew Dick,Lawrence R. Gahan,Gerhard Schenk,Graeme R. Hanson,Flávia C. S. de Paula,Elene C. Pereira-Maia,Sergio Machado,Patricia Cardoso Severino,Claus Tröger Pich,Tiago Bortolotto,Hernán Terenzi,Eduardo E. Castellano,Ademir Neves,Mark J. Riley +21 more
TL;DR: This study establishes benchmarks against accurate crystallographic structural information using spectroscopic techniques that are not restricted to single crystals and shows that the cytotoxic activity of the biomimetics on leukemia and lung tumoral cells is highest for complexes with electron-donating groups.
Journal ArticleDOI
Physical Exercise For Parkinson's Disease: Clinical And Experimental Evidence.
Alessandro Carvalho,Alberto Souza de Sá Filho,Eric Murillo-Rodríguez,Nuno Rocha,Mauro Giovanni Carta,Sergio Machado +5 more
TL;DR: Physical exercise contributes effectively to the treatment of Parkinson's Disease, and can play a preventive and maintenance role of physical fitness and mental health.
Journal ArticleDOI
Can transcranial direct current stimulation on the dorsolateral prefrontal cortex improves balance and functional mobility in Parkinson's disease?
Eduardo Lattari,Samara Sezana Costa,Carlos Campos,Carlos Campos,Aldair J. Oliveira,Sergio Machado,Geraldo de Albuquerque Maranhão Neto +6 more
TL;DR: Compensatory mechanisms that support motor function in individuals with PD may have been enhanced by a-tDCS on the DLPFC, leading to improved functional mobility and balance.
Journal ArticleDOI
Index of Alpha/Theta Ratio of the Electroencephalogram: A New Marker for Alzheimer’s Disease
Magali Taino Schmidt,Paulo Afonso Medeiros Kanda,Luis F. H. Basile,Helder F. S. Lopes,Regina Baratho,Jose Demario,Mário Silva Jorge,Antonio Egidio Nardi,Sergio Machado,Jéssica Natuline Ianof,Renato Anghinah,Ricardo Nitrini +11 more
TL;DR: Logistic regression of alpha/theta of the spectrum of the mean potential of EEG represents a good marker discriminating AD patients from normal controls.
