Muscle and Nerve, 2000
Bothrops jararacussu venom and its major toxin, bothropstoxin-I (BthTX-I), possess myotoxic and neurotoxic activities. The ability of commercial equine antivenom to neutralize these activities was studied in mouse isolated phrenic nerve-diaphragm (PND) and extensor digitorum longus (EDL) preparations by indirect stimulation (0.1 HZ, 0.2 ms).

Primary Structure Characterization of Bothrops Jararacussu Snake Venom Lectin
The Protein Journal, 2002The complete amino acid sequence of the lectin from Bothrops jararacussu snake venom (BJcuL) is reported. The sequence was determined by Edman degradation and amino acid analysis of the S-carboxymethylated BJcuL derivative (RC-BJcuL) and from its peptides originated from enzymatic digestion.

Is snake venom activity influenced by size? This is a long-standing question that can have important consequences for the treatment of snake envenomation. Ontogenetic shifts in venom composition are a well-documented characteristic of numerous snake species.

Crystallization of bothropstoxin II isolated from the venom of Bothrops jararacussu
Toxicon, 1996A myotoxic phospholipase A2, bothropstoxin II, which exhibits low hydrolytic activity, was crystallized and X-ray diffraction data were collected to a resolution of 2.2 A. Preliminary analysis reveals the presence of three molecules in the asymmetric unit.

Antagonism of the myotoxic effects of Bothrops jararacussu venom and bothropstoxin by polyanions
Toxicon, 1993The effects of heparin and other polyanions on the myotoxicity of Bothrops jararacussu venom and purified bothropstoxin (BthTX) were investigated. The release rate of creatine kinase (CK) from isolated extensor digitorum longus muscle and the plasma CK activity of mice were used to quantify the results. The myotoxic effects of B.

The karyotypes presented were obtained from short term blood cultures. The 4th pair of macrochromosomes is heteromorphic in the female ZW. The karyotypes are from a male from Espirito Santo and a female from Sao Paulo, Brazil. The specimens are included in the Collection of the Instituto But antan.

Biological activities of a lectin from Bothrops jararacussu snake venom
Toxicon, 2006Snake venoms contain saccharide-binding lectins. In this work, we examined the biological activities of a lectin (BjcuL) purified from Bothrops jararacussu snake venom by chromatography on non-derivatized Sepharose 4B and Sephacryl S-200 HR. The protein, a homodimer with subunits of 14.5 kDa, gave a single immunoprecipitin line in immunoelectrophoresis

Ontogenetic study of Bothrops jararacussu venom composition reveals distinct profiles
Toxicon, 2020Concerning snake venoms, numerous authors worked with different species of Bothrops focusing on the ontogeny of these animals. However, according to PubMed database, no results on studies related to Bothrops jararacussu ontogeny were displayed until now. This fact led us to develop a greater interest in the venom ontogenetic variability of this species,

Irradiation of the Crude Venom of Bothrops jararacussu to Obtain Toxoid
AIP Conference Proceedings, 2011The aim of this work was to reduce the toxicity of Bothrops jararacussu venom using gamma‐rays of low‐energy coming from a source of Americium‐241 (E = 59.6 keV and 3.7×109 Bq of activity) in order to obtain a toxoid. The radiation dose that each sample received was controlled by exposure time of the venom to the radiation beam.
