1. Deep sequencing analysis of toad Rhinella schneideri skin glands and partial biochemical characterization of its cutaneous secretion
Abstract Background: Animal poisons and venoms are sources of biomolecules naturally selected. Rhinella schneideri toads are widespread in the whole Brazilian territory and they have poison glands and mucous gland. Recently, protein from toads’ secretion has gaining attention. Frog skin is widely known to present great number of host defense peptides and

2. Synergic effects between ocellatin-F1 and bufotenine on the inhibition of BHK-21 cellular infection by the rabies virus
Abstract Background Rabies is an incurable neglected zoonosis with worldwide distribution characterized as a lethal progressive acute encephalitis caused by a lyssavirus. Animal venoms and secretions have long been studied as new bioactive molecular sources, presenting a wide spectrum of biological effects, including new antiviral agents. Bufotenine, for i

3. Antileishmanial and antitrypanosomal activity of the cutaneous secretion of Siphonops annulatus
Background Among the tropical parasitic diseases, those caused by protozoans are considered a challenge to public health, being represented by leishmaniasis and Chagas disease. In view of the low effectiveness and toxicity of the current therapy, animal venoms such as amphibian secretions have been used as a promising source of new drug prototypes. The pr

4. Comparison between two methods of scorpion venom milking in Morocco
Background The present study compared two methods used successfully in a large-scale program for the collection of scorpion venoms, namely the milking of adult scorpions via manual and electrical stimulation. Results Our immunobiochemical characterizations clearly demonstrate that regularly applied electrical stimulation obtains scorpion venom more easily a

5. Local alterations induced by the toxic secretion of Philodryas patagoniensis (Serpentes: Colubridae) / Alterações locais induzidas pela secreção tóxicas de Philodryas patagoniensis (Girard, 1857) (Serpentes: Colubridae)
The venom of Philodryas patagoniensis causes important and similar local lesions the ones that happen in the botropic accidents. The mechanisms involved in the local actions of this venom are little known. This study has as objective investigates the morphologic and inflammatory local actions of the venom of Philodryas patagoniensis and the mechanisms involv

6. Vias de sinalização desencadeadas pela estimulação do adrenoceptor b em células secretoras da glândula de veneno da serpente Bothrops jararaca. / Signaling pathways triggered by the stimulation of the b adrenoceptor in secretory cells of the venom gland of the snake Bothrops jararaca.
O adrenoceptor b está presente na glândula de veneno de Bothrops jararaca, tanto no estado quiescente como no ativado por 4 dias, entretanto, quando estimulado, aumenta os níveis de AMPc somente em células secretoras no estado quiescente. Neste trabalho, estudamos funcionalmente o adrenoceptor b durante o ciclo de

7. Contribution to the investigation of hemostatic disturbances induced by Bothrops jararaca snake venom in rabbits: study of platelet membrane glycoproteins, function, secretion and survival. / Contribuição à investigação das alterações hemostáticas induzidas pelo veneno da serpente Bothrops jararaca em coelhos: estudo das glicoproteínas da membrana, função, secreção e sobrevivência plaquetárias.
Que o envenenamento pela serpente Bothrops jararaca causa distúrbios hemorrágicos sistêmicos, com alteração da coagulação e fibrinólise sangüíneas, é notório. Contudo, pouco se sabe sobre a ação in vivo desse veneno sobre as plaquetas. Em estudos recentes, demonstrou-se que esse veneno causa trombocitopenia, distúrbios da agregação e diminui

8. One scorpion, two venoms: Prevenom of Parabuthus transvaalicus acts as an alternative type of venom with distinct mechanism of action
Scorpion venom is a complex mixture of salts, small molecules, peptides, and proteins. Scorpions employ this valuable tool in several sophisticated ways for subduing prey, deterring predators, and possibly during mating. Here, a subtle but clever strategy of venom utilization by scorpions is reported. Scorpions secrete a small quantity of transparent venom w
