13. The Cuban scorpion Rhopalurus junceus (Scorpiones, Buthidae): component variations in venom samples collected in different geographical areas
Backgound The venom of the Cuban scorpion Rhopalurus junceus is poorly study from the point of view of their components at molecular level and the functions associated. The purpose of this article was to conduct a proteomic analysis of venom components from scorpions collected in different geographical areas of the country. Results Venom from the blue scorp

14. Effects of atropine and propranolol on lung inflammation in experimental envenomation: comparison of two buthidae venoms
Background Previous works had shown that scorpion venom induced neurotransmitter elevation and an inflammatory response associated with various anatomo-pathological modifications. The most dangerous scorpions species in Algeria responsible for these effects are Androctonus australis hector (Aah) and Androctonus amoreuxi (Aam). Results Comparison of the phys

15. 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

16. Estudo da ação do veneno de Tityus serrulatus sobre a expressão de transportadores de sódio e água em epitélio alveolar de rato / Effect of Tityus serrulatus venom on sodium and water trasporters in rat alveolar epithelium
Acidentes escorpiônicos podem evoluir com edema pulmonar de origem cardiogênica e não cardiogênica. O clearance de edema pulmonar está relacionado principalmente ao transporte ativo de sódio do espaço alveolar para o interstício. O objetivo deste trabalho foi avaliar os efeitos do veneno de Tityus serrulatus e da dexametasona sobre a expressão dos t

17. Scorpionism in Central America, with special reference to the case of Panama
Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Cost

18. Avaliação da atividade antiviral de peçonhas de serpentes e escorpião contra os vírus da dengue e da febre amarela / Evaluation of antiviral activity of snake and scorpion venoms against dengue and yellow fever virus
A dengue é a mais importante arbovirose no mundo; aproximadamente 50 milhões de infecções ocorrem anualmente acarretando 500.000 casos de dengue hemorrágica e 22.000 mortes. A febre amarela é uma doença hemorrágica viral com elevada mortalidade que é transmitida por mosquitos. Vacinas eficazes contra a febre amarela já estão disponíveis há quase

19. In vivo and in vitro effects of scorpion venoms in Turkey: a mini-review
Scorpion stings constitute a common type of accident in Turkey due to the geographic location, climate and socioeconomic structure of this country. Moreover, envenomation cases are considered a public health problem throughout Turkey. Based on data in the literature, the main clinical features of scorpion envenomations are defined as systemic manifestations

20. Individual variation in the protein profile of the venom of Mesobuthus gibbosus (Brullé, 1832, Scorpiones: Buthidae) from Turkey
Mesobuthus gibbosus (Brullé, 1832) scorpions were collected from the Mugla province in the Aegean region of Turkey and housed in individual boxes. After extraction, the venom composition was analyzed using gel electrophoresis (SDS-PAGE). Interestingly, all scorpion venom samples contained only one protein band (~68 kDa) in common. Two protein bands (30 and

22. Análise proteômica parcial da peçonha do escorpião colombiano Centruroides margaritatus (Gervais, 1841)
Scorpion venoms are a complex mixture of peptides that exert their action via ion-channel modulation in biological membranes. The central objective of this project was to perform the proteomic characterization of the venom from the Colombian scorpion Centruroides margaritatus. This species is capable of producing moderate accidents and serious complications

23. Evaluation of the neutralizing capacity of Androctonus crassicauda (Olivier, 1807) antivenom against Leiurus quinquestriatus (Ehrenberg, 1928) venom (Scorpiones: Buthidae)
The two most venomous species of the family Buthidae, Leiurus quinquestriatus and Androctonus crassicauda, are found in Africa and in the Middle East. Potency and paraspecific activities of A. crassicauda antivenom (RSHC anti-Ac) were tested against L. quinquestriatus venom. The sera produced by Refik Saydam Hygiene Center (RSHC) showed strong reactivity aga

24. Biological effects induced by Tityus serrulatus crude venom and its toxins TsTx-V, gamma toxin and natriuretic peptide / Efeitos biolÃgicos induzidos pelo veneno total de Tityus serrulatus e suas fraÃÃes TsTx-V, toxina gama e peptÃdeo natriurÃtico
The venom of Tityus serrulatus has a mixture of toxic and non toxic peptides presenting diverse systemic and local effects. The aim of this work was to investigate the cardiovascular and renal effects promoted by the crude venom of the scorpion Tityus serrulatus and its isolated components such as Tityus serrulatus toxin V (TsTx-V), Gamma Toxin and the newly
