Eficácia e seguran?a do cateter "Pronto" para aspira??o manual de trombo durante angioplastia primária no infarto agudo do miocárdio com eleva??o do segmento ST
Santos, Márcio Ant?nio dos;Fonseca, Carlos Guilherme B.;Godoy, Moacir Fernandes de;
Revista Brasileira de Cardiologia Invasiva , 2007, DOI: 10.1590/S2179-83972007000200009
Abstract: objectives: the aim of this study was to evaluate the efficacy and safety of the pronto? extraction catheter to aspirate thrombus during percutaneous coronary intervention (pci) in patients presenting with st-segment elevation acute myocardial infarction (stemi) methods: twenty-eight unselected patients (60% male, age 60.5 ± 11.7 years) were treated with pci with manual thrombus aspiration using the pronto? catheter. all the patients had acute myocardial infarction with st-elevation (stemi), and presented up to 12 hours after the onset of clinical symptoms. were analyzed myocardial blush grade (mbg), reduction grade of epicardical distal flow (timi), distal embolization, st resolution and procedure time. results: the patients select treated with thrombectomy during primary angioplasty for acute myocardial infarction did not show distal or side branch occlusion, slow flow or no-reflow and had evidence of microvascular reperfusion. conclusion: the use of pronto? thrombectomy catheter is feasible and safe, without significant increase the procedural time. the use of this device was associated with indirect signs of successful reperfusion at microvascular level.
Electroantennographic responses of Heterotermes tenuis (Isoptera: Rhinotermitidae) to synthetic (3Z,6Z,8E)-Dodecatrien-1-ol
Batista-Pereira Luciane G.,Santos Márcio G. dos,Corrêa Arlene G.,Fernandes Jo?o B.
Journal of the Brazilian Chemical Society , 2004,
Abstract: The subterranean termite Heterotermes tenuis (Isoptera: Rhinotermitidae) is a pest of great importance for the Brazilian economy as it causes serious damages in commercial reforestations of Eucalyptus spp. and sugarcane cultures. (3Z,6Z,8E)-Dodecatrien-1-ol has been identified as a pheromone of some species of subterranean termites. The objective of this research was to synthesize (3Z,6Z,8E)-dodecatrien-1-ol and determine by electroantennographic (EAG) bioassays the selectivity and sensitivity of H. tenius antennae to its whole worker extract and to the synthetic triene alcohol.

Abstract: objective: to follow the evolution of the breastfeeding practice among women in a childbirth clinic and evaluate the actions for its promotion. methods: two cohorts of children born in an school hospital of porto alegre, brazil, in different periods of time were compared regarding the prevalence of breastfeeding during the first six months of life, and the percentage of early cessation of breastfeeding. both were prospective studies, including 202 children in the cohort of 1987, and 187 children in the cohort of 1994. all participants were healthy children, with birth weight of 2500g or more, were being breastfed and their parents were living in the same house. the 1987 study children were followed up through mail, and the 1994 study ones by home visits. results: survival analysis showed similar frequencies of breastfeeding in the two cohorts. the prevalence of exclusive breastfeeding, although for a short period in both groups, was higher in the population studied in 1994, especially among children whose mothers were better educated. there was no rate difference of early cessation of breastfeeding between the two cohorts (36% for the 1987 cohort and 39% for the 1994 cohort). conclusions: the results revealed a certain degree of apathy in regard of the promotion of breastfeeding during the studied period, giving support to actions to promote breastfeeding, especially among poor families.
Study of Corrosion Resistance of Laser Welded Au-Pd-Ag-In Alloy Using Electrochemical Techniques  [PDF]
Márcio L. Dos Santos, Heloísa A. Acciari, Carla S. Riccardi, Antonio C. Guastaldi
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.27098
Abstract: The aim of this work was to evaluate the corrosion resistance of AuPdAgIn alloy, submitted to laser beam welding, in 0.9% NaCl solution, using electrochemical techniques. Measures of the open circuit potential (OCP) versus time were applied to electrochemical experiments, as well as potentiodynamic direct scanning (PDS) and electrochemical impedance spectroscopy (EIS) on AuPdAgIn alloy, submitted to laser beam welding in 0.9% NaCl solution. Some differences observed in the microstructure can explain the results obtained for corrosion potential, Ecorr, and corrosion resistance, Rp. EIS spectra have been characterized by distorted capacitive components, presenting linear impedance at low frequencies, including a non-uniform diffusion. The area of the laser weld presented corrosion potential slightly superior when compared to the one of the base metal. The impedance results suggest the best resistant corrosion behavior for laser weld than base metal region. This welding process is a promising alternative to dental prostheses casting.
Os relatos de reconhecimento de Quaresma Delgado
Santos, Márcio Roberto Alves dos;
Varia Historia , 2008, DOI: 10.1590/S0104-87752008000200021
Abstract: the itineraries of quaresma delgado, explorer contracted by colonial authorities to investigate and map part of minas gerais and bahia "sert?o" in the 1730's, are studied as tipical accounts of reconnaissance, characteristic of a period when the exploration and mapping of the territory fortified themselves as illustrated scientific practices. the text - the account of reconnaissance - and the cartographic image - the map - produced by quaresma delgado are treated as constituent elements mutually complementary of a technical study, whose central aim is to describe, in a controlled language, the natural and human landscapes observed by the explorer.
Socio-Environmental and Sustainability Assessment for Technology Innovations at Pectens Production in Brazil
Márcio Ricardo Costa dos Santos
Journal of technology management & innovation , 2008,
Abstract: This study presents a practical impact assessment method for the adoption of technology innovations at Pectens In vitro Fertilization Laboratory in Rio de Janeiro State, Brazil. To fulfill the system framework requirements, focused on reproductive and productive enterprises, field visits and interview with the laboratory executive director were carried out. Considering the pectens production activities, 24 socio-environmental indicators were developed and the impact indices were automatically calculated by the system’s spreadsheets. General performance index for the pectens reproduction activities indicated an important contribution of technological innovations for the sustainable production of the In vitro Fertilization Laboratory. The employed method was considered as appropriate for evaluations of sustainability at this agribusiness activity, dealing with indicators as tools in order to identify possible risks for negative impacts. Those indicators include aspects beyond those commonly presented by environmental impact assessments, and were capable to provide adequate management and sustainable development for the studied Organization.

Carlos, Iracilda Z.;Carli, Camila B. A.;Maia, Danielle C. G.;Benzatti, Fernanda P.;Lopes, Flavia C. M.;Roese, Fernanda M.;Watanabe, Márcio;Micheletti, Ana C.;Santos, Lourdes C. dos;Vilegas, Wagner;Honda, Neli K.;
Revista Brasileira de Farmacognosia , 2009, DOI: 10.1590/S0102-695X2009000600009
Abstract: the effects of isolated compounds from brazilian lichens and their derivatives on h2o2 and no production were studied using murine macrophages as a part of an attempt to understand their possible immunomodulatory properties. the compound cytotoxicity was studied using mtt assay. macrophage stimulation was evaluated by the determination of no (griess assay) and h2o2 (horseradish peroxidase/phenol red) in supernatants of peritoneal macrophage cultures of swiss mice. this research demonstrated stimulatory activities of some phenolic compounds isolated from lichens and their derivatives on h2o2 and no production. structure-activity relationships suggest several synthetic directions for further improvement of immunological activity.
