Is rainfall seasonality important for reproductive strategies in viviparous Neotropical pit vipers? A case study with Bothrops leucurus from the Brazilian Atlantic Forest
(British Herpetol Soc, 2014-04-01)
Two populations of the Neotropical lancehead Bothrops leucurus were studied in two locations in Brazil (Espirito Santo, ES, and Bahia, BA) with different rainfall seasonality patterns. The timing of reproduction was very ...
Seasonal Activity of Bothrops jararaca (Serpentes, Viperidae): Optimizing Foraging while Avoiding Predators
(2021-08-01)
The peak of activity of Bothrops jararaca is in the rainy season. This pitviper feeds mainly on small mammals and is preyed upon by several avian and mammal predators. However, the association between jararaca's seasonal ...
Purification, crystallization and preliminary X-ray diffraction analysis of a class P-III metalloproteinase (BmMP-III) from the venom of Bothrops moojeni
(Wiley-Blackwell, 2012-10-01)
Snake-venom metalloproteinases (SVMPs) comprise a family of haemostatically active toxins which can cause haemorrhage, coagulopathy, inhibition of platelet aggregation and inflammatory response. These effects are attributed ...
In vivo effects of Bothrops jararaca venom on metabolic profile and on muscle protein metabolism in rats
(2008-01-01)
This study investigated the in vivo effects of the Bothrops jararaca venom (BjV) on general metabolic profile and, specifically, on muscle protein metabolism in rats. The crude venom (0.4 mg/kg body weight, IV) was infused ...
Phenotypic differences in a cryptic predator: Factors influencing morphological variation in the terciopelo Bothrops asper (Garman, 1884; Serpentes: Viperidae)
(Elsevier Ltd, 2009)
The terciopelo Bothrops asper, is a cryptic lancehead pitviper widely distributed in humid environments of Middle America and the north-western portion of South America. Throughout its extensive distribution range, the ...
Does gestation or feeding affect the body temperature of the golden lancehead, Bothrops insularis (Squamata: Viperidae) under field conditions?
(Sociedade Brasileira de Zoologia, 2010-01-01)
Temperature affects physiological performance in reptiles and, therefore, body temperature (Tb) control is argued to have an important adaptive value. Alterations in Tb due to transient changes in physiological state, as ...
Crystallization and preliminary X-ray diffraction analysis of suramin, a highly charged polysulfonated napthylurea, complexed with a myotoxic PLA(2) from Bothrops asper venom
(Elsevier B.V., 2004-12-01)
Suramin is a highly charged polysulfonated napthylurea that interferes in a number of physiologically relevant processes such as myotoxicity, blood coagulation and several kinds of cancers. This synthetic compound was ...
Crytallization and high-resolution X-ray diffraction data collection of an Asp49 PLA(2) from Bothrops jararacussu venom both in the presence and absence of Ca2+ ions
(Elsevier B.V., 2004-12-01)
Snake venom PLA(2)s have been extensively studied due to their role in mediating and disrupting physiological processes such as coagulation, platelet aggregation and myotoxicity. The Ca2+ ion bound to the putative ...
Inflammatory infiltrate in skeletal muscle injected with Bothrops asper venom
(1986)
The time-course and composition of inflammatory infiltrate in mouse gastrocnemius injected with Bothrops asper venom was studied. The venom induced myonecrosis, and a prominent decrease in muscle levels of creatine kinase ...
Isolation from a polyvalent antivenom of antibodies to a myotoxin in Bothrops asper snake venom
(1985)
Antibodies against Bothrops asper rmyotoxin were purified from a polyvalent antivenom by affinity chromatography . These antibodies neutralized most of the myotoxic activity of crude B. asper venom, as judged by histologic ...
