PHYLOGENY OF SOME MIDDLE AMERICAN PITVIPERS BASED ON A CLADISTIC ANALYSIS OF MITOCHONDRIAL 12S AND 16S DNA SEQUENCE INFORMATION [PDF]
The cladistic relationships of several Middle American pitvipers representing the genera Bothrops (sensu stricto), Bothriechis, Cerrophidion, Lachesis and Porthidium were determined using mitochondrial 12S and 16S DNA sequence information.

Snake Venom Protease Detection and Inhibition in Serum. [PDF]
A fluorescence assay enables sensitive detection of the activities of snake venom metalloproteases (SVMP) and serine proteases (SVSP) from viper venoms in buffer and serum. In combination with effective low‐molecular‐weight inhibitors such as ilomastat and nafamostat, this approach offers new prospects for the rapid diagnosis and adjunctive therapy of ...

Crotalus atrox venom preconditioning increases plasma fibrinogen and reduces perioperative hemorrhage in a rat model of surgical brain injury. [PDF]
Perioperative bleeding is a potentially devastating complication in neurosurgical patients, and plasma fibrinogen concentration has been identified as a potential modifiable risk factor for perioperative bleeding.

Guidelines for the diagnosis and differential diagnosis of snakebite envenoming of ruminants in Brazil [PDF]
: In Brazil, snakebites are often cited as a cause of mortality in ruminants, but there are discrepancies in the literature regarding its actual prevalence, either by lack of diagnosis or by mistakes in the differential diagnosis.

A snake of a different color: physiological color change in Arizona black rattlesnakes [PDF]
Coloration may serve a variety of behavioral (e.g., crypsis, communication) and physiological (e.g., thermoregulation, protection) functions for terrestrial ectotherms. However, optimal coloration for a given function may vary over environments (spatial

Electrical field-induced contractions on Crotalus durissus terrificus and Bothrops jararaca aortae are caused by endothelium-derived catecholamine. [PDF]
Endothelium is the main source of catecholamine release in the electrical-field stimulation (EFS)-induced aortic contractions of the non- venomous snake Panterophis guttatus.

Background Many snakes are low-energy predators that use crypsis to ambush their prey. Most of these species feed very infrequently, are sensitive to the presence of larger vertebrates, such as humans, and spend large portions of their lifetime hidden ...

Evolution of the eyes of vipers with and without infrared-sensing pit organs [PDF]
We examined lens and brille transmittance, photoreceptors, visual pigments, and visual opsin gene sequences of viperid snakes with and without infrared-sensing pit organs. Ocular media transmittance is high in both groups.
