1. Functional and biological insights of rCollinein-1, a recombinant serine protease from Crotalus durissus collilineatus
ABSTRACT Background: The prevalent class of snake venom serine proteases (SVSP) in Viperidae venoms is the thrombin-like enzymes, which, similarly to human thrombin, convert fibrinogen into insoluble fibrin monomers. However, thrombin-like serine proteases differ from thrombin by being unable to activate factor XIII, thus leading to the formation of loose c

2. General characterization of venom from the Moroccan snakes Macrovipera mauritanica and Cerastes cerastes
Ophidian envenomation accidents constitute a serious public health problem in many countries around the globe. Over 5 million such accident cases occur each year causing more than 100,000 deaths. In Africa, more than 20,000 deaths per year are registered while 400,000 envenomation victims retain severe and permanent functional sequelae. In Morocco, snakebite

3. Avaliação da atividade antiofídica do composto p-cumarato de triacontila isolado de Bombacopsis glabra e da toxicidade aguda do extrato de Schizolobium parahyba
The use of plant extracts as antidote against animals venoms is an old practice, mainly envenomations by snakes, besides also may used as supplemental of serum therapy. Snake venoms are a rich mixture of proteins involved in a complex series of events that depends on the synergic action of these molecules. The present study explores the ability of Triacontil

4. Estudo das atividades das cabenegrinas A-I e A-II frente aos efeitos hematolÃgicos e histolÃgicos induzidos pelo veneno total e fraÃÃes da serpente Bothrops neuwiedi em camundongos Swiss. / Study of the activities of cabenegrinas A-I and A-II compared to the histological and hematological effects induced by the venom and fractions of the snake Bothrops neuwiedi in Swiss mice.
The venom of the Bothrops neuwiedi provokes an action mainly of the hemorrhagic, proteolytic and coagulant type. When inoculated, the venom cause primarily a local action, and secondarily a systemic action. The systemic effects of poisoning include changes in various systems such as hematological, cardiovascular, liver, urinary, respiratory, immune, digestiv

5. PurificaÃÃo e CaracterizaÃÃo Parcial de duas Hemorraginas Ativadoras de Fator X da PeÃonha de Bothrops leucurus (jararaca do rabo branco) (Wagler, 1824)
Hemorragia à uma patologia que ocorre devido à anormalidade das funÃÃes dos fatores da coagulaÃÃo, do endotÃlio dos vasos sanguÃneos e/ou das plaquetas. Enzimas da peÃonha dos ViperÃdeos, designadas hemorraginas, toxinas hemorrÃgicas ou ainda fatores hemorrÃgicos sÃo as principais responsÃveis pelo quadro hemorrÃgico (local e sistÃmico) apres
