1. A checklist of the scorpions of Ecuador (Arachnida: Scorpiones), with notes on the distribution and medical significance of some species
Ecuador harbors one of the most diverse Neotropical scorpion faunas, hereby updated to 47 species contained within eight genera and five families, which inhabits the “Costa” (n= 17), “Sierra” (n= 34), “Oriente” (n= 16) and “Insular” (n= 2) biogeographical regions, corresponding to the western coastal, Andean, Amazonian, and the Galápagos arc

2. Resistance of cervical adenocarcinoma cells (HeLa) to venom from the scorpion Centruroides limpidus limpidus
Background : The venom of Centruroides limpidus limpidus (Cll) is a mixture of pharmacologically active principles. The most important of these are toxic proteins that interact both selectively and specifically with different cellular targets such as ion channels. Recently, anticancer properties of the venom from other scorpion species have been described.

3. 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

4. Acidente causado por Centruroides testaceus (DeGeer, 1778) (Scorpiones, Buthidae), nativo do Caribe, em aeroporto brasileiro
Descreve-se um caso de menina de 6 anos de idade picada por um Centruroides testaceus, escorpião nativo das Antilhas, no interior do Aeroporto Internacional de Guarulhos, São Paulo, Brasil, após ter desembarcado de um vôo vindo do Caribe. A paciente apresentou apenas sintomas locais (pequena área de eritema e dor no local da picada), resolvidos em algum

5. A newly described scorpion species, Leiurus abdullahbayrami (Scorpion: Buthidae), and the lethal potency and in vivo effects of its venom
Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identifi

6. 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

7. Amino acid sequence determination and chemical synthesis of CllErg1 (gamma-KTx1.5), a K+ channel blocker peptide isolated from the scorpion Centruroides limpidus limpidus
Uma nova toxina denominada CllErg1 (nomenclatura sistemática gama-KTx1.5) foi purificada do veneno do escorpião Centruroides limpidus limpidus e a sua seqüência de amino ácidos foi determinada. Ela tem 42 resíduos de amino ácidos entrecruzados por quatro pontes de disulfetos e bloqueia especificamente um canal de potássio da família eter-a-go-go (ER

10. Centruroides toxin, a selective blocker of surface Na+ channels in skeletal muscle: voltage-clamp analysis and biochemical characterization of the receptor.
This paper describes the effects of a toxin from the scorpion Centruroides suffusus suffusus on frog skeletal muscle. The main findings are the following, (i) Centruroides toxin (CssII) blocks the early phase of the inward sodium current in the muscle that arises from influx via Na+ channels in the surface membrane, but it does not affect the late phase of t

11. Centruroides exilicauda Envenomation in Arizona
A retrospective survey of 1,135 telephone calls during 1980 and 1981, reporting scorpion envenomation to the Arizona Poison and Drug Information Center, was reviewed. Of these, 438 calls identified Centruroides exilicauda as the offending scorpion on the basis of description of the arthropod and consistency of physical findings and clinical course. Envenomat

12. Reconstitution of highly purified saxitoxin-sensitive Na+-channels into planar lipid bilayers.
Highly purified Na+-channels isolated from rat brain have been reconstituted into virtually solvent-free planar lipid bilayer membranes. Two different types of electrically excitable channels were detected in the absence of any neurotoxins. The activity of both channels was blocked by saxitoxin. The first channel type is highly selective for Na+ over K+ (app
