Production of white wine by Saccharomyces cerevisiae immobilized on grape pomace
Genisheva, Z.; Macedo, S.; Mussatto, Solange I.; Teixeira, J. A.; Oliveira, J. M.White wine was produced with Saccharomyces cerevisiae cells immobilized on grape pomace, by natural adsorption. The support, the main solid waste from the wine industry, consisted of the skins, seeds and stems. Immobilization was tested using different media, namely complex culture medium, raw grape must and diluted grape must. Grape pomace was revealed to be an appropriate support for yeast cell immobilization...
Canine cricopharyngeal achalasia: case report
Malm,C; Souza,E.M; Ferian,P.E; Fukushima,F.B; Macedo,S.P; Ladeira,O.H.R; Faria,A.B.F; Andrade,M.G.M.GA 7-month-old miniature poodle female dog was referred with dysphagia. After clinical, radiographic, and endoscopic examination, it was diagnosed a probable case of cricopharyngeal achalasia. The patient underwent surgical treatment and presented normal swallowing and no regurgitation after 24 hours post-surgery. Positive recovery and progressive body weight gain until 180 days after surgery was observed
Central 5-HT2A receptors modulate the vagal bradycardia in response to activati...
Futuro Neto,H.A.; Macedo,S.M.; Silva,N.F.; Cabral,A.M.; Pires,J.G.P.Activation of 5-hydroxytryptamine (5-HT) 5-HT1A, 5-HT2C, 5-HT3, and 5-HT7 receptors modulates the excitability of cardiac vagal motoneurones, but the precise role of 5-HT2A/2B receptors in these phenomena is unclear. We report here the effects of intracisternal (ic) administration of selective 5-HT2A/2B antagonists on the vagal bradycardia elicited by activation of the von Bezold-Jarisch reflex with phenylbigua...
Avaliação preliminar da atividade antimicrobiana do extrato de erva-mate (Ilex ...
Carelli,G; Macedo,S.M.D; Valduga,A.T; Corazza,M.L; Oliveira,J.V; Franceschi,E; Vidal,R; Jaskulski,M.RIlex paraguariensis A. St. - Hil. (erva-mate) é uma árvore pertencente à família Aquifoleaceae, nativa da região sul da América do Sul e de grande importância cultural e econômica para os três estados da região sul do Brasil. O presente trabalho determinou o potencial antimicrobiano do extrato de erva-mate obtido por fluido supercrítico, frente a alguns microrganismos. As folhas de Ilex paraguariensis foram col...

O "ouro castanho" despertou um crescente interesse entre os diferentes povos, que lhe atribuíam um variado conjunto de propriedades terapêuticas, tendo algumas delas prevalecido até à actualidade. ...
Structure of a dioxygen reduction enzyme from Desulfovibrio gigas
Frazão, Carlos; Silva, Gabriela; Gomes, Claudio; Matias, Pedro; Coelho, R; Sieker, L; Macedo, S; Liu, MY; Oliveira, Solange; Teixeira, MiguelDesulfovibrio gigas is a strict anaerobe that contains a well-characterized metabolic pathway that enables it to survive transient contacts with oxygen. The terminal enzyme in this pathway, rubredoxin:oxygen oxidoreductase (ROO) reduces oxygen to water in a direct and safe way. The 2.5 Angstrom resolution crystal structure of ROO shows that each monomer of this homodimeric enzyme consists of a novel combination...
