Biochemical and biological evaluation of gyroxin isolated from Crotalus durissus terrificus venom
(Centro de Estudos de Venenos e Animais Peçonhentos - CEVAP, Universidade Estadual Paulista - UNESP, 2011)
Gyroxin, a thrombin-like enzyme isolated from Crotalus durissus terrificus venom and capable of converting fibrinogen into fibrin, presents coagulant and neurotoxic activities. The aim of the present study was to evaluate ...
Purificação e caracterização parcial de uma serino-protease tipo tripsina isolada do intestino de larvas de Lutzomyia longipalpis (Diptera, Psychodidae)
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
Visceral Leishmaniasis is a disease of major public health impact. In the New World the diasease is caused by Leishmania infantum chagasi and transmitted mainly by Lutzomyia longipalpis. In adult sandflies, trypsins play ...

Thrombomodulin-independent activation of protein C and specificity of hemostatically active snake venom serine proteinases - Crystal structures of native and inhibited Agkistrodon contortrix contortrix protein C activator
(Amer Soc Biochemistry Molecular Biology Inc, 2005-11-25)
Protein C activation initiated by the thrombin-thrombomodulin complex forms the major physiological anticoagulant pathway. Agkistrodon contortrix contortrix protein C activator, a glycosylated single-chain serine proteinase, ...
Duvernoy's gland secretion of Philodryas patagoniensis from the northeast of Argentina: Its effects on blood coagulation
(Pergamon-Elsevier Science Ltd, 2005-03)
Duvernoy's gland secretion of Philodryas patagoniensis exhibits high hemorrhagic activity, containing enzymes that are able to degrade the vascular wall. In this work we aim to determine if the secretion can also affect ...
Atividade coagulante e da toxidade da giroxina nativa e irradiada com Cobalto-60 isolada do veneno de Crotalus durissus terrificus
(Universidade Estadual Paulista (Unesp), 2010-06-29)
A giroxina isolada do veneno de Crotalus durissus terrificus apresenta atividades coagulante e neurotóxica, caracterizada pelo “rolamento em barril”. É uma serinoprotease do tipo trombina-símile que tem a capacidade de ...
characterization of serine-proteases from P. hypophthalmus epithelial mucus as a potential feedstock for biocosmetic applications
Chemical peeling is a cosmetical treatment that promotes skin renewal, by the remotion of
skin layers through the appliance of corrosive compounds. It has proven to be successful for
the removal of acne, scars, photoaging, ...

Studies related to progesterone-induced hamster sperm acrosome reaction
(1996)
Experiments were designed to characterize the effect of progesterone on the hamster sperm acrosome reaction (AR). Progesterone stimulated exocytosis of previously capacitated spermatozoa in a dose-dependent manner. ...
Antitumoural effect of an L-amino acid oxidase isolated from Bothrops jararaca snake venom
(Wiley-Blackwell, 2008-06-01)
An L-amino acid oxidase (BjarLAAO-I) from Bothrops jararaca snake venom was highly purified using a stepwise sequential chromatography on Sephadex G-75, Benzamidine Sepharose and Phenyl Sepharose. Purified BjarLAAO-I showed ...
