Os radicais livres de oxigênio e as doen?as pulmonares
Andrade Júnior, Dahir Ramos de;Souza, Rodrigo Becco de;Santos, Sania Alves dos;Andrade, Dahir Ramos de;
Jornal Brasileiro de Pneumologia , 2005, DOI: 10.1590/S1806-37132005000100011
Abstract: oxygen free radicals are molecules that present unpaired electrons in their outer orbit and can transform other molecules such as proteins, carbohydrates, lipids and deoxyribonucleic acid. oxygen free radicals are produced in various clinical conditions in which hypoxic microenvironments are generated and reoxygenation follows. such situations include clinical shock, septicemia, systemic inflammatory response, fulminant hepatitis, organ transplant and respiratory failure. in this review, we discuss the main concepts related to oxygen free radicals: the principal types and their formation, as well as the way in which they affect cellular structures and cause significant tissue damage. we present also the main antioxidants that guard against oxidative stress, including glutathione, glutathione peroxidase, superoxide dismutase, catalase, and n-acetylcysteine. the influence of oxygen free radicals on the principal pulmonary diseases are also discussed, with special emphasis given to oxygen free radicals in cigarette smoke, chronic obstructive pulmonary disease, asthma, sleep apnea syndrome and acute respiratory distress syndrome.

Brazilian Journal of Otorhinolaryngology , 2011, DOI: 10.1590/S1808-86942011000400011
Abstract: acoustic rhinometry, rhinomanometry and inspiratory peak nasal flow (ipnf) are used in order to objectively assess nasal patency. these are expensive not very practical tests, except for ipnf, which is a fast, simple and low cost method. objective: to assess ipnf in healthy individuals complaining of nose obstruction caused by allergic rhinitis. method: ipnf use in 78 individuals with and without rhinitis symptoms. study design: contemporary cross-sectional cohort. results: ipnf showed significant results for nasal obstruction, rhinorrhea, pruritus, sneezes and tearing (p < 0. 001). there was no correlation between the presence of nasal septum deviation and ipnf (p = 0. 561). we found a positive correlation between ipnf and the visual analogue scale (vas) for nasal obstruction (p = 0. 002). in the multiple linear regression model, there was a statistical significance between the values found in ipnf with allergic rhinitis and age (p = 0. 005 and p = 0. 023 respectively). conclusions: ipnf proved to be a reliable method to detect changes in nasal patency, by obstructive causes as well as inflammatory causes, with an acceptable level of statistical significance, simple, easy to handle, inexpensive and reproducible

Revista E-Psi , 2012,
Abstract: This study intends to investigate the articulation between two predictors of school achievement – the g factor of intelligence and the students’ beliefs about the process of teaching and learning. There were 101 students participants of a federal high school of Belo Horizonte. Four tests of the BaFaCAlO and some items of the CrEA were applied. And the quarterly note of Portuguese, mathematics, physics and chemistry was used as measure of the school incomes. The full Structural Equation Modeling was managed to define five models about the relations between g, beliefs and academic proficiency. The models had been compared using the difference between its qui-squares and degrees of freedom and with the statistical variables CFI and RMSEA. The results indicated equivalence between the models, concerning to the data adjustment; that g is a strong predictor of school incomes and that beliefs doesn’t show predictive power. Although the prominences evidences, a non linear relation between beliefs and school performance was verified, suggesting that only strong beliefs have implications to the proficiency. New studies are necessary to investigate this result.

Piovan, Leandro;Alves, Márcio F. M;Juliano, Luiz;Br?mme, Dieter;Cunha, Rodrigo L. O. R;Andrade, Leandro H;
Journal of the Brazilian Chemical Society , 2010, DOI: 10.1590/S0103-50532010001100012
Abstract: a series of organoselenium dihalides (organoselenanes) was synthesized from organoselenides using a chemoenzymatic approach. the organoselenanes have variations in their stereochemistry and in the halogen atom bonded to the selenium atom. because of the unique selenium-thiol chemistry displayed by several organoselenium compounds, the organoselenanes were evaluated as new potential inhibitors of cysteine proteases (cathepsins s and v). by the analysis of the second-order rate constants of the inhibition of cathepsin s and v, it was possible to conclude that organoselenanes inhibited the cathepsin s faster than cathepsin v. it was observed higher inhibitory potencies for the dibromo organoselenanes derivatives than the dichloro analogues. in addition, the present data suggest the use of hypervalent selenium compounds as novel motifs for cysteine proteases inhibitors.
