The interaction of bothropstoxin-I (Lys49-PLA(2)) with liposome membranes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Bothropstoxin-I (BthTx-I) is a Lys49-PLA(2) from the venom of the snake Bothrops jararacussu, which permeabilizes biological and artificial membranes by a mechanism independent of lipid hydrolysis. This mechanism has been ...
Effects of chemical modifications of crotoxin B, the phospholipase A2 subunit of crotoxin from Crotalus durissus terrificus snake venom, on its enzymatic and pharmacological activities
Crotoxin B, the basic Asp49-PLA2 subunit from crotoxin, the main component of Crotalus durissus terrificus venom, displays myotoxic, edema-inducing, bactericidal (upon Escherichia coli), liposomal-disrupting and anticoagulant ...
Synthesis, characterization and spectroscopy of the europium doped lanthanum trimetaphosphate
Orthorhombic modification of europium doped lanthanum trimetaphosphate has been prepared. The compound was obtained by precipitation of rare earth chloride solution with trimetaphosphoric acid. The characterizations were ...
Modified woodflour as thermoset fillers Part I. Effect of the chemical modification and percentage of filler on the mechanical properties
Composites made from an unsaturated polyester/styrene thermoset matrix and esterified woodflour have been prepared and tested. Different degrees of esterification of the wood particles with maleic anhydride were obtained ...
A new approach to chemical modification protocols of Aspergillus niger and sorption of lead ion by fungal species
(Pontificia Universidad Católica de Valparaíso, 2006)
Identification of functionally important acidic residues in transducin by group-specific labeling
(Sociedad de Biología de Chile, 2003)
Effect of chemical modifications on the electronic structure of poly(3-hexylthiophene)
The widespread use of poly(3-hexylthiophene) (P3HT) in the active layers of organic solar cells indicates that it possesses chemical stability and solubility suitable for such an application. However, it would be desirable ...
