1. Hemorrhagic stroke in children caused by Bothrops marajoensis envenoming: a case report
Abstract According to the World Health Organization, snakebites are considered neglected diseases. Bothrops, the genus most frequently implicated in envenomations in Brazil, includes the species B. marajoensis Hoge, 1966, part of the complex B. atrox, which is found in the savannas of Marajó Island, Pará state, Brazil, a region that presents scarce epidemi

2. Pharmacological and partial biochemical characterization of Bmaj-9 isolated from Bothrops marajoensis snake venom
Bmaj-9, a basic PLA2 (13679.33 Da), was isolated from Bothrops marajoensis snake venom through only one chromatographic step in reversed phase HPLC on ¼-Bondapak C-18 column. The amino acid composition showed that Bmaj-9 had a high content of Lys, His, and Arg, typical of a basic PLA2. The sequence of Bmaj-9 contains 124 amino acid residues with a pI value

3. AvaliaÃÃo dos efeitos renais da fraÃÃo L-aminoÃcido Oxidase isolada do veneno da serpente Bothrops marajoensis. / Assessment of renal effects of L-amino acid oxidase fraction isolated from snake Bothrops marajoensis venom.
There are about 3.000 species of snakes worldwide, but only 10 to 14% are venomous. Among South American countries, Brazil is the one with the largest number of accidents, with approximately 20.000 snakebites each year. According to the Department of Health of Brazil, the genus Bothrops are the main involved in snakebites in the country. Acute renal failure

4. CaracterizaÃÃo das atividades cardiorenal e neural de Bothrops marajoensis e suas fraÃÃes / CHARACTERIZATION OF TOTAL VENOM AND ITS FRACTION FROM THE Bothrops marajoensis IN CARDIORENAL AND NEURAL ACTIVITIES
Avaliou-se a atividade de Bothrops marajoensis (Bmj) e suas fraÃÃes no sistema cardiorrenal. A resposta pressora do veneno bruto demonstrou uma diminuiÃÃo da pressÃo arterial mÃdia e da freqÃÃncia cardÃaca, sem alteraÃÃes significativas na freqÃÃncia respiratÃria. Em ratos atropinizados demonstrou a permanÃncia dos efeitos. Na perfusÃo de cor

5. AÃÃo antibacteriana antifÃngica e antiparasitÃria de veneno de serpentes do gÃnero Bothrops e suas fraÃÃes fosfolipase A2 e L-AminoÃcido oxidase / Antibacterial, antifungal and antiparasitary action of Bothrops venoms and their fractions phospholipase A2 and L-aminoacid oxidase
Snakes venoms contain biologically active substances primarily consisting of proteins (90-95%). Some of these present enzymatic activities, such as phospholipases A2 and the L-amino acid oxidases. In this study we verify the action of Bothrops leucurus (BleuTV) and Bothrops marajoensis (BmarTV) venoms, and fractions PLA2 (BleuPLA2 and BmarPLA2) and LAAO (Ble

6. Characterization of proteolityc, hemorrhagic and edematogenic activities of BmHF-1 metallproteinase, isolet from Bothrops marajoensis crude venom / Caracterização das atividades proteolitica, hemorragica e edematogenica de uma metaloprotease BmHF-1 isolada a partir do veneno total de Bothrops marajoensis
In this present work we described the isolation, structural and functional characterization of a new metalloproteinase, named BmHF-1. This protein was isolated with a high degree of purity from the Bothrops marajoensis snake venom by the combination of two chromatographic steps, size exclusion in a Superdex G-75 column coupled to HPLC biocompatible system, f

7. Structural and functional characterisation of a serine proteinase TLBm, isolated starting from the Bothrops marajoensis whole venom / Caracterização estrutural e funcional de uma serinoprotease TLBm, isolada a partir do veneno total de Bothrops marajoensis
Muitas das toxinas isoladas e estudadas em seus efeitos biológicos precisam ser reavaliadas à luz de metodologias otimizadas em HPLC e confirmadas por espectrometria de massas, devido à possível presença de algum componente não estudado. No caso da serpente Bothrops marajoensis, são valorizados os estudos sobre essa espécie devido aos poucos trabalho

8. Estudo das atividades neurotoxica e miotoxica de uma fosfolipase A2 basica isolada do veneno total Bothrops marajoensis / Study of neurotoxic and myotoxic activities of a phospholipase A2 isolated from the Bothrops marajoensis venom
In the present work, the neuromuscular effects of the toxin Bmaj-9 isolated from the venom of Bothrops marajoensis in the laboratory of chemistry of proteins at Unicamp were studied. This toxin was assayed in biventer cervicis preparations of little chicken, phrenic diaphragm nerve of mice and in gastrocnemius muscles of mice. In birds preparation, Bmaj-9 ca
