Materials Sciences and Applications (MSA) , 2010, DOI: 10.4236/msa.2010.15041
Abstract: ZnO nanowires were synthesised in a green and novel, two-step process: (1) the production of Zn nanowires by carbo-thermal reduction of a mixture of ZnO/biopitch (Eucalyptus sp. tar pitch) at 900°C for 1 h in a quartz tube placed in an electric furnace in a N2 atmosphere and (2) the oxidation of the as-prepared Zn nanowires in air at 300°C for 3 h and 6 h and at 400°C for 3 h. The structural properties and phase compositions of the oxidised samples were studied by X-ray diffraction (XRD), and the morphologies were investigated by scanning electron microscopy (SEM). The XRD results demonstrated the formation of ZnO phase, as the main product. The oxidised products exhibited good crystallinity. Maximal conversion of the Zn nanowires into ZnO nanowires (99%) resulted from oxidation of the sample for 3 h in air at 300°C. The formation of ZnO was also confirmed by Fourier transform infrared (FTIR) spectroscopy.

Abstract: Attenuated yellow fever (YF) virus 17D/17DD vaccines are the only available protection from YF infection, which remains a significant source of morbidity and mortality in the tropical areas of the world. The attenuated YF virus vaccine, which is used worldwide, generates both long-lasting neutralizing antibodies and strong T-cell responses. However, on rare occasions, this vaccine has toxic side effects that can be fatal. This study presents the design of two non-viral DNA-based antigen formulations and the characterization of their expression and immunological properties. The two antigen formulations consist of DNA encoding the full-length envelope protein (p/YFE) or the full-length envelope protein fused to the lysosomal-associated membrane protein signal, LAMP-1 (pL/YFE), aimed at diverting antigen processing/presentation through the major histocompatibility complex II precursor compartments. The immune responses triggered by these formulations were evaluated in H2b and H2d backgrounds, corresponding to the C57Bl/6 and BALB/c mice strains, respectively. Both DNA constructs were able to induce very strong T-cell responses of similar magnitude against almost all epitopes that are also generated by the YF 17DD vaccine. The pL/YFE formulation performed best overall. In addition to the T-cell response, it was also able to stimulate high titers of anti-YF neutralizing antibodies comparable to the levels elicited by the 17DD vaccine. More importantly, the pL/YFE vaccine conferred 100% protection against the YF virus in intracerebrally challenged mice. These results indicate that pL/YFE DNA is an excellent vaccine candidate and should be considered for further developmental studies.

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.718263
Abstract: Although there has been a large amount of research on reading performance among Brazilian children, very little has been done on both home and school experiences and their influence on children’s literacy and language skills and research has focused on children rather than on adolescent samples. The main question we ask on this study is whether perceived early print experience by adolescents and reading enjoyment relates to students reading performance in present day. Thirty-one adolescents participated in this research. They were enrolled in middle school and were from less affluent areas of the State of Rio de Janeiro. They answered a questionnaire about their perceived home literacy experiences in early age, a reading enjoyment scale and three reading measure tests. The results of the correlations carried out in the data showed that teenagers with higher home literacy scores made fewer errors in reading single words.

Abstract: objective: to describe a new more efficient method of endocardial cardiac stimulation, which produces a narrower qrs without using the coronary sinus or cardiac veins. methods: we studied 5 patients with severe dilated cardiomyopathy, chronic atrial fibrillation and av block, who underwent definitive endocardial pacemaker implantation, with 2 leads, in the rv, one in the apex and the other in the interventricular septum (sub pulmonary), connected, respectively, to ventricular and atrial bicameral pacemaker outputs. using doppler echocardiography, we compared, in the same patient, conventional (vvi), high septal ("aai") and bifocal ("ddt" with av interval ~ 0) stimulation. results: the rv bifocal stimulation had the best results with an increase in ejection fraction and cardiac output and reduction in qrs duration, mitral regurgitation and in the left atrium area (p £ 0.01). the conventional method of stimulation showed the worst result. conclusion: these results suggest that, when left ventricular stimulation is not possible, right ventricular bifocal stimulation should be used in patients with severe cardiomyopathy where a pacemaker is indicated.
