Professor José Roberto Giglio and toxinnology in Brazil: 48 years in research 80
Soares,A. M.; Oliveira,C. Z.; Santana,C. D.; Menaldo,D. L.; Silveira,L. B.; Teixeira,S. S.; Rueda,A. Q.; Marcussi,S..
This work succinctly describes the professional and scientific life of Dr. José R. Giglio, one of the most outstanding Brazilian researchers in the field of Toxinology. During his long and successful career, he has made major contributions, especially in elucidating the function, structure, and mechanisms of action of animal venom proteins (from snakes, scorpions and spiders) as well as the characterization of antibodies and several inhibitors of venoms and toxins. We present here a brief history of Dr. Giglio’s personal and professional life, also reporting some of his numerous published scientific articles on venoms from snakes (Bothrops, Crotalus, and other genera), scorpions (Tityus sp), spiders (Phoneutria sp), their isolated toxins and natural...

Purification and functional characterization of two fibrinogenolytic enzymes from Bothrops alternatus venom 80
Costa,J. O.; Petric,C. B.; Hamaguchi,A.; Homsi-Brandeburgo,M. I.; Oliveira,C. Z.; Soares,A. M.; Oliveira,F..
Two fibrinogenolytic enzymes, Bothrops alternatus metalloprotease isoform (BaltMP)-I and II, were purified from Bothrops alternatus venom using Diethylaminoethyl (DEAE) Sephacel, Sephadex G-75 and Heparin-Agarose column chromatography. Purified BaltMP-I and II ran as single protein bands on analytical polyacrylamide gel electrophoresis and showed molecular weights of 29000 and 36000, respectively, under reducing conditions in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). BaltMP-II, but not BaltMP-I, displayed blood-clotting activity in bovine plasma, which was about 10-fold higher than that of the crude venom. Both enzymes were proteolytically active against bovine fibrinogen as substrate. When fibrinogen and each enzyme were...
