Zinc(II) phthalocyanines immobilized in mesoporous silica Al-MCM-41 and their a...
Silva, M.; Calvete, M. J. F.; Gonçalves, N. P. F.; Burrows, H. D.; Sarakha, M.; Fernandes, A.; Ribeiro, M. F.; Azenha, M. E; Pereira, M. M.In the present study the authors investigated a set of three new zinc(II) phthalocyanines (zinc(II) tetranitrophthalocyanine (ZnTNPc), zinc(II) tetra(phenyloxy)phthalocyanine (ZnTPhOPc) and the tetraiodide salt of zinc(II)tetra(N,N,N-trimethylaminoethyloxy) phthalocyaninate (ZnTTMAEOPcI)) immobilized into Al-MCM-41 prepared via ship-in-a-bottle methodology. The samples were fully characterized by diffuse reflec...
Quantificação de transcritos maternos em oócitos bovinos submetidos a diferente...
Pereira,M.M; Costa,F.Q; Oliveira,A.P; Serapião,R.V; Machado,M.A; Viana,J.H. M; Camargo,L.S.AComparou-se a quantidade relativa de transcritos de origem materna entre oócitos bovinos maturados in vivo e maturados em diferentes condições in vitro. Avaliou-se também o efeito dos sistemas de maturação in vitro sobre a viabilidade das células do cumulus. Para a maturação in vivo, os oócitos foram coletados 19-20h após aplicação de gonadorelina em doadoras superestimuladas com FSH e sincronizadas com implant...
1,3-Butadiene hydrogenation on pd-supported systems: geometric effects
Souza,P.R.N.; Pereira,M.M.; Antunes,O.A.C.; Aranda,D.A.G.; Carneiro,J.W.M.A strong metal support interaction (SMSI) effect was observed on Pd/Nb2O5 and Pd/TiO2 catalysts, and it produces small, exposed Pd ensembles. A decrease in the trans/cis 2-butene ratio was observed after reduction at 773 K. Selectivity changes were ascribed to the decoration model. Theoretical models were developed based on semi-empirical molecular-orbital calculations for 1,3-butadiene and Pd n clusters. Exper...
Propriedades biomecânicas da fáscia lata e do ligamento cruzado cranial de cães
Brendolan,A.P.; Rezende,C.M.F.; Pereira,M.M.Preparações bilaterais do ligamento cruzado cranial e da fáscia lata de 15 cães foram testadas na máquina Instron, modelo 4482. Os animais, de ambos os sexos, idade entre um e quatro anos, pesavam em média 11,80 ± 1,99kg. Os retalhos de fáscia lata foram testados retilíneos e torcidos e o ligamento cruzado cranial foi testado mantendo um ângulo de 135° entre a tíbia e o fêmur e 0°, 15° de rotação externa e 15° ...
Synthesis, reactivity and catalytic properties of rhodium complexes of (R,R)-1-...
Diéguez, M.; Ruiz, A.; Claver, C.; Pereira, M. M.; Flor, M. T.; Bayón, J. C.; Serra, M. E. S.; Rocha Gonsalves, A. M. d'A.Complexes [Rh(cod)(degusR)]ClO4, where cod is 1,5-cyclooctadiene and degusR represents the homochiral dithioethers (R,R)-1-benzyl-3,4-bis(methylsulfanyl)pyrrolidine, (R,R)-1-benzyl-3,4-bis(isopropylsulfanyl)pyrrolidine and (R,R)-1-benzyl-3,4-bis(phenylsulfanyl)pyrrolidine were prepared and characterized. Their reactivity with CO and PPh3 was investigated. The complexes were assayed as catalysts in hydroformylat...
Human leptospirosis in a slum area in the city of Rio de Janeiro, Brazil: a ser...
Pereira,M. M.; Andrade,J.A serologic survey was carried out on slum dwellers in the city of Rio de Janeiro. A total of 259 serum samples from male and female individuals of different age groups were tested for the presence of antileptospire antibodies by microagglutination. Prevalence data were analyzed in relation to the major risk factors present at the site, mainly represented by the presence of carrier animals and the occurence of ...
