Laccase-catalysed protein-flavonoid conjugates for flax fibre modification
Kim, S; Paulo, Artur CavacoThe introduction of flavonoid compounds into proteins can improve the natural properties of proteins, being promising products which essentially require antioxidant property. The oxidative conjugation of protein–flavonoids was processed by laccase catalysis resulting in the synthesis of biologically functional polymers. The new reaction products were detected in terms of sodium dodecyl sulfate polyacrylamide ge...
Polymerization of lignosulfonates by the laccase-HBT (1-hydroxybenzotriazole) s...
Prasetyo, E. N.; Kudanga, T.; Østergaard, L.; Rencoret, J.; Gutiérrez, A.; Río, J. C. del; Santos, J. I.; Nieto, L.; Jiménez-Barbero, JesúsThe ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572% from 28400 Da a...
Estudo comparativo entre anastomoses intestinais com sutura manual e com anel b...
Fernandes,L. C.; Matos,D.; Novelli,M. D.; Kim,S. B.OBJETIVO: Este estudo analisou anastomoses intestinais por sutura manual e por compressão com anel biofragmentável, sob retardo cicatricial pela administração parenteral de corticosteróides. MATERIAL E MÉTODOS: Vinte cães, entre 15 e 20 kg, foram divididos em grupos controle e teste, este submetido à administração intramuscular de hemissuccinato de hidrocortisona, de 25 a 33 mg/kg/dia, do 30º dia pré-operatório...
