Evaluation of the antischistosomal activity of sulfated α-D-glucan from th...
Araújo,R.V.S.; Melo-Júnior,M.R.; Beltrão,E.I.C.; Mello,L.A.; Iacomini,M.; Carneiro-Leão,A.M.A.; Carvalho Jr,L.B.; Santos-Magalhães,N.S.The antischistosomal activity of the sulfated polysaccharide α-D-glucan (Glu.SO4) extracted from Ramalina celastri was evaluated after encapsulation into liposomes (Glu.SO4-LIPO) in Schistosoma mansoni-infected mice. The effect of treatment with Glu.SO4 and Glu.SO4-LIPO (10 mg/kg) on egg elimination, worm burden and hepatic granuloma formation was assessed using female albino Swiss mice, 35-40 days of age,...
Purification of a lectin from Eugenia uniflora L. seeds and its potential antib...
Oliveira, M. D. L.; Andrade, C. A. S.; Magalhães, N. S.; Coelho, L. C. B. B.; Teixeira, J. A.; Cunha, M. G. C.; Correia, M. T. S.Aims: The aim of this work was to analyse the antimicrobial properties of a purified lectin from Eugenia uniflora L. seeds. Methods and Results: The E. uniflora lectin (EuniSL) was isolated from the seed extract and purified by ion-exchange chromatography in DEAE-Sephadex with a purification factor of 11·68. The purified lectin showed a single band on denaturing electrophoresis, with a molecular mass of 67 kDa...
The gravitational wave detector "Mario Schenberg": status of the project
Aguiar,O.D.; Andrade,L.A.; Camargo Filho,L.; Costa,C.A.; Araujo,J.C.N. de; Rey Neto,E.C. del; Souza,S.T. de; Fauth,A.C.; Frajuca,C.; Frossati,G.The first phase of the Brazilian Graviton Project is the construction and operation of the gravitational wave detector Mario Schenberg at the Physics Institute of the University of São Paulo. This gravitational wave spherical antenna is planned to feature a sensitivity better than h = 10-21 Hz-1/2 at the 3.0-3.4 kHz bandwidth, and to work not only as a detector, but also as a testbed for the development of new ...
