A genus of snakes of the family VIPERIDAE, one of the pit vipers, so-called from the pit hollowing out the maxillary bone, opening between the eye and the nostril. They are distinctively American serpents. Most of the 25 recognized species are found in the southwestern United States and northern Mexico. Several species are found as far north as Canada and east of the Mississippi, including southern Appalachia. They are named for the jointed rattle (Greek krotalon) at the tip of their tail. (Goin, Goin, and Zug: Introduction to Herpetology, 3d ed; Moore: Poisonous Snakes of the World, 1980, p335)
Venoms from snakes of the subfamily Crotalinae or pit vipers, found mostly in the Americas. They include the rattlesnake, cottonmouth, fer-de-lance, bushmaster, and American copperhead. Their venoms contain nontoxic proteins, cardio-, hemo-, cyto-, and neurotoxins, and many enzymes, especially phospholipases A. Many of the toxins have been characterized.
A specific complex of toxic proteins from the venom of Crotalus durissus terrificus (South American rattlesnake). It can be separated into a phospholipase A and crotapotin fragment; the latter consists of three different amino acid chains, potentiates the enzyme, and is specifically neurotoxic.
Limbless REPTILES of the suborder Serpentes.
Solutions or mixtures of toxic and nontoxic substances elaborated by snake (Ophidia) salivary glands for the purpose of killing prey or disabling predators and delivered by grooved or hollow fangs. They usually contain enzymes, toxins, and other factors.
Proteins obtained from species of REPTILES.
Bites by snakes. Bite by a venomous snake is characterized by stinging pain at the wound puncture. The venom injected at the site of the bite is capable of producing a deleterious effect on the blood or on the nervous system. (Webster's 3d ed; from Dorland, 27th ed, at snake, venomous)
Antisera used to counteract poisoning by animal VENOMS, especially SNAKE VENOMS.
A family of snakes comprising three subfamilies: Azemiopinae (the mountain viper, the sole member of this subfamily), Viperinae (true vipers), and Crotalinae (pit vipers). They are widespread throughout the world, being found in the United States, Central and South America, Europe, Asia and Africa. Their venoms act on the blood (hemotoxic) as compared to the venom of elapids which act on the nervous system (neurotoxic). (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, pp333-36)

An enzyme that catalyzes the oxidative deamination of L-amino acids to KETO ACIDS with the generation of AMMONIA and HYDROGEN PEROXIDE. L-amino acid oxidase is widely distributed in and is thought to contribute to the toxicity of SNAKE VENOMS.
A genus of poisonous snakes of the VIPERIDAE family. About 50 species are known and all are found in tropical America and southern South America. Bothrops atrox is the fer-de-lance and B. jararaca is the jararaca. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p336)
Poisonous animal secretions forming fluid mixtures of many different enzymes, toxins, and other substances. These substances are produced in specialized glands and secreted through specialized delivery systems (nematocysts, spines, fangs, etc.) for disabling prey or predator.
A family of polypeptides purified from snake venoms, which contain the arginine-glycine-aspartic acid (RGD) sequence. The RGD tripeptide binds to integrin receptors and thus competitively inhibits normal integrin-ligand interactions. Disintegrins thus block adhesive functions and act as platelet aggregation inhibitors.
Phospholipases that hydrolyze one of the acyl groups of phosphoglycerides or glycerophosphatidates.

Phosphatidylinositol 3'-kinase and tyrosine-phosphatase activation positively modulate Convulxin-induced platelet activation. Comparison with collagen. (1/124)

In this report we have studied the role of phosphatidylinositol 3'-kinase (PI3-K) and tyrosine phosphatase activation on platelet activation by Convulxin (Cvx). Wortmannin, a specific PI3-K inhibitor, and phenylarsine oxide (PAO), a sulfhydryl reagent that inhibits tyrosine phosphatase (PTPase), block Cvx-induced platelet aggregation, granule secretion, inositol phosphate production, and increase in [Ca2+]i. However, PAO does not inhibit Cvx-induced tyrosine phosphorylation of platelet proteins, including Syk and PLCgamma2, but blocked collagen-induced platelet aggregation as well as tyrosine phosphorylation of PLCgamma2. In contrast, Cvx-induced PLCgamma2 tyrosyl phosphorylation was partially inhibited by wortmannin. We conclude that (i) although Cvx and collagen activate platelets by a similar mechanism, different regulatory processes are specific to each agonist; (ii) mechanisms other than tyrosine phosphorylation regulate PLCgamma2 activity; and (iii) besides protein tyrosine kinases, PI3-K (and PTPase) positively modulate platelet activation by both Cvx and collagen, and this enzyme is required for effective transmission of GPVI-Fc receptor gamma chain signal to result in full activation and tyrosine phosphorylation of PLCgamma2 in Cvx-stimulated platelets.  (+info)

Combining phage display and molecular modeling to map the epitope of a neutralizing antitoxin antibody. (2/124)

Crotoxin is a potent presynaptic neurotoxin from the venom of the rattlesnake Crotalus durissus terrificus. It is composed of the noncovalent and synergistic association of a weakly toxic phospholipase A2, CB, and a nontoxic three-chain subunit, CA, which increases the lethal potency of CB. The A-56.36 mAb is able to dissociate the crotoxin complex by binding to the CA subunit, thereby neutralizing its toxicity. Because A-56.36 and CB show sequence homology and both compete for binding to CA, we postulated that A-56.36 and CB had overlapping binding sites on CA. By screening random phage-displayed libraries with the mAb, phagotopes bearing the (D/S)GY(A/G) or AAXI consensus motifs were selected. They all bound A-56.36 in ELISA and competed with CA for mAb binding, although with different reactivities. When mice were immunized with the selected clones, polyclonal sera reacting with CA were induced. Interestingly, the raised antibodies retained the crotoxin-dissociating effect of A-56.36, suggesting that the selected peptides may be used to produce neutralizing antibodies. By combining these data with the molecular modeling of CA, it appeared that the functional epitope of A-56.36 on CA was conformational, one subregion being discontinuous and corresponding to the first family of peptides, the other subregion being continuous and composed of amino acids of the second family. Phage-displayed peptides corresponding to fragments of the two identified regions on CA reacted with A-56.36 and with CB. Our data support the hypothesis that A-56.36 and CB interact with common regions of CA, and highlight residues which are likely to be critical for CA-CB complex formation.  (+info)

Interaction of the neurotoxic and nontoxic secretory phospholipases A2 with the crotoxin inhibitor from Crotalus serum. (3/124)

Crotalus durissus terrificus snakes possess a protein in their blood, named crotoxin inhibitor from Crotalus serum (CICS), which protects them against crotoxin, the main toxin of their venom. CICS neutralizes the lethal potency of crotoxin and inhibits its phospholipase A2 (PLA2) activity. The aim of the present study is to investigate the specificity of CICS towards snake venom neurotoxic PLA2s (beta-neurotoxins) and nontoxic mammalian PLA2s. This investigation shows that CICS does not affect the enzymatic activity of pancreatic and nonpancreatic PLA2s, bee venom PLA2 and Elapidae beta-neurotoxins but strongly inhibits the PLA2 activity of Viperidae beta-neurotoxins. Surface plasmon resonance and PAGE studies further demonstrated that CICS makes complexes with monomeric and multimeric Viperidae beta-neurotoxins but does not interact with nontoxic PLA2s. In the case of dimeric beta-neurotoxins from Viperidae venoms (crotoxin, Mojave toxin and CbICbII), which are made by the noncovalent association of a PLA2 with a nonenzymatic subunit, CICS does not react with the noncatalytic subunit, instead it binds tightly to the PLA2 subunit and induces the dissociation of the heterocomplex. In vitro assays performed with Torpedo synaptosomes showed a protective action of CICS against Viperidae beta-neurotoxins but not against other PLA2 neurotoxins, on primary and evoked liberation of acetylcholine. In conclusion, CICS is a specific PLA2 inhibitor of the beta-neurotoxins from the Viperidae family.  (+info)

The disulfide bond pattern of catrocollastatin C, a disintegrin-like/cysteine-rich protein isolated from Crotalus atrox venom. (4/124)

The disulfide bond pattern of catrocollastatin-C was determined by N-terminal sequencing and mass spectrometry. The N-terminal disintegrin-like domain is a compact structure including eight disulfide bonds, seven of them in the same pattern as the disintegrin bitistatin. The protein has two extra cysteine residues (XIII and XVI) that form an additional disulfide bond that is characteristically found in the disintegrin-like domains of cellular metalloproteinases (ADAMs) and PIII snake venom Zn-metalloproteinases (SVMPs). The C-terminal cysteine-rich domain of catrocollastatin-C contains five disulfide bonds between nearest-neighbor cysteines and a long range disulfide bridge between CysV and CysX. These results provide structural evidence for a redefinition of the disintegrin-like and cysteine-rich domain boundaries. An evolutionary pathway for ADAMs, PIII, and PII SVMPs based on disulfide bond engineering is also proposed.  (+info)

Shaking up glycolysis: Sustained, high lactate flux during aerobic rattling. (5/124)

Substantial ATP supply by glycolysis is thought to reflect cellular anoxia in vertebrate muscle. An alternative hypothesis is that the lactate generated during contraction reflects sustained glycolytic ATP supply under well-oxygenated conditions. We distinguished these hypotheses by comparing intracellular glycolysis during anoxia to lactate efflux from muscle during sustained, aerobic contractions. We examined the tailshaker muscle of the rattlesnake because of its uniform cell properties, exclusive blood circulation, and ability to sustain rattling for prolonged periods. Here we show that glycolysis is independent of the O(2) level and supplies one-third of the high ATP demands of sustained tailshaking. Fatigue is avoided by rapid H(+) and lactate efflux resulting from blood flow rates that are among the highest reported for vertebrate muscle. These results reject the hypothesis that glycolysis necessarily reflects cellular anoxia. Instead, they demonstrate that glycolysis can provide a high and sustainable supply of ATP along with oxidative phosphorylation without muscle fatigue.  (+info)

A comparison of RAPD versus microsatellite DNA markers in population studies of the massasauga rattlesnake. (6/124)

We compared genetic differentiation among populations of the threatened massasauga rattlesnake (Sistrurus c. catenatus) using two types of nuclear molecular markers: randomly amplified polymorphic DNA (RAPD) markers and microsatellites. Analyses of molecular variance (AMOVA) and G(ST) and F(ST) analyses indicated that levels of among-population differentiation between regional populations (>100 km) were comparable for both markers. However, microsatellites were superior in population assignment tests and at discerning fine-scale genetic differentiation between subpopulations separated by tens of kilometers. These results argue that both types of markers are suitable for defining broad-scale genetic structures in snake populations and can provide important inputs into conservation initiatives of focal taxa. However, our analyses suggest that microsatellites 3re better for detecting structure at limited spatial scales.  (+info)

Insights into population ecology and sexual selection in snakes through the application of DNA-based genetic markers. (7/124)

Hypervariable genetic markers have revolutionized studies of kinship, behavioral ecology, and population biology in vertebrate groups such as birds, but their use in snakes remains limited. To illustrate the value of such markers in snakes, we review studies that have used microsatellite DNA loci to analyze local population differentiation and parentage in snakes. Four ecologically distinct species of snakes all show evidence for differentiation at small spatial scales (2-15 km), but with substantial differences among species. This result highlights how genetic analysis can reveal hidden aspects of the natural history of difficult-to-observe taxa, and it raises important questions about the ecological factors that may contribute to restricted gene flow. A 3-year study of genetic parentage in marked populations of the northern water snake showed that (1) participation in mating aggregations was a poor predictor of genetic-based measures of reproductive success; (2) multiple paternity was high, yet there was no detectable fitness advantage to multiple mating by females; and (3) the opportunity for selection was far higher in males than in females due to a larger variance in male reproductive success, and yet this resulted in no detectable selection on morphological variation in males. Thus genetic markers have provided accurate measures of individual reproductive success in this species, an important step toward resolving the adaptive significance of key features including multiple paternity and reversed sexual size dimorphism. Overall these studies illustrate how genetic analyses of snakes provide previously unobtainable information of long-standing interest to behavioral ecologists.  (+info)

Purification and characterisation of a haemorrhagic fraction from the venom of the Uracoan rattlesnake Crotalus vegrandis. (8/124)

Uracoan rattlesnake (Crotalus vegrandis) venom was subjected to chromatographic, electrophoretic, biochemical and in vivo haemorrhagic analysis. A haemorrhagic toxin (Uracoina-1) active on skin at the site of inoculation in mice was purified by Mono Q2 anion-exchange chromatography and size exclusion (SE) high-performance liquid chromatography. The purified preparation was a protein of M(r) 58,000 as revealed by sodium dodecyl sulphate--polyacrylamide gel electrophoresis under denatured conditions and with silver staining. The use of EDTA, EGTA and 1,10-phenanthroline inhibited haemorrhagic and proteolytic activities. Inhibitors of serine proteinases such as PMSF and TCLK had no effect on the haemorrhagic fraction. Uracoina-1 hydrolyses casein, hide powder azure and fibrinogen have an optimal pH of 8.2. It rapidly digests the A alpha-chain of fibrinogen. Thermal denaturation of Uracoina-1 after exposure at 60 degrees C for 15 min led to inactivation of the haemorrhagic activity. In addition, Uracoina-1 is myotoxic, lacking haemolytic, defibrinating and lethal effects. The N-terminal amino acid sequence (20 residues) was determined.  (+info)

The eastern diamondback rattlesnake is the largest rattlesnake species and is one of the heaviest known species of venomous snake, with one specimen shot in 1946 measuring 7.8 ft (2.4 m) in length and weighing 15.4 kg (34 lb). However, other venomous snakes may rival this species in weight. The much longer but more slender king cobra is probably greater in average body mass if not maximum weight, and the shorter but even bulkier Gaboon viper could (but is not verified to) exceed the eastern diamondback rattlesnake in both mean adult body mass and possibly even maximum body mass.[6][7][8] Maximum reported lengths for the eastern diamondback rattlesnake are 8 ft (2.4 m)[9] and 8.25 ft (2.5 m).[10][11] However, the stated maximum sizes have been called into question due to a lack of voucher specimens.[12][13] Males are larger than females. Specimens over 7 ft (2.1 m) are rare, but well documented. Klauber (1998) included a letter he received from E. Ross Allen in 1953, in which Allen explains how ...

The venom of Crotalus durissus terrificus snakes presents various substances, including a serine protease with thrombin-like activity, called gyroxin, that clots plasmatic fibrinogen and promote the fibrin formation. The aim of this study was to purify and structurally characterize the gyroxin enzyme from Crotalus durissus terrificus venom. For isolation and purification, the following methods were employed: gel filtration on Sephadex G75 column and affinity chromatography on benzamidine Sepharose 6B; 12% SDS-PAGE under reducing conditions; N-terminal sequence analysis; cDNA cloning and expression through RT-PCR and crystallization tests. Theoretical molecular modeling was performed using bioinformatics tools based on comparative analysis of other serine proteases deposited in the NCBI (National Center for Biotechnology Information) database. Protein N-terminal sequencing produced a single chain with a molecular mass of similar to 30 kDa while its full-length cDNA had 714 bp which encoded a ...

These snakes may reach ages beyond 20 years of age. Unlike most snakes, the males are larger than the females. This may be a result of selection for large males that will win the arduous male-male, non-lethal wrestling contests that allow the winner to breed with a nearby female.. Females will produce a clutch of up to around 20 live-born babies that are especially large in size. The myth that baby diamondback rattlesnakes hide underground, and grow for a few years before surfacing, likely comes from the fact that few people realize that an 18-inch rattlesnake is actually a newborn. Like all other rattlesnakes yet studied, the female will stay with her young and protect them until their first shed cycle, at which time they will disperse on their own.. ...

A crotoxin homolog was purified from the Crotalus durissus collilineatus venom using molecular exclusion and reverse-phase HPLC. This crotoxin contained one PLA2 (Cdcolli III F6) and four crotapotin isoforms, whereas crotoxin from Crotalus durissus terrificus venom had three PLA2 isoforms and two crotapotin isoforms. SDS-PAGE showed that the C. d. collilineatus PLA2 and crotapotin had relative molecular mass of 15 and 9 kDa, respectively. Neither the PLA2 (Cdcolli III F6) nor the crotapotins (Cdcolli III F3 and F4) had any neurotoxicity in mouse phrenic nerve-diaphragm preparations when tested alone. However, when PLA2 and crotapotin were coincubated before testing, the neurotoxicity was restored to a level similar to test in the venom in native crotoxin. The two crotapotins (Cdcolli III F3 and F4) differed in their ability to inhibit PLA2 activity, perhaps because of variations in their affinities for this enzyme. Cdcolli III F6 showed allosteric enzymatic behavior, with maximal activity at pH ...
The timber rattlesnake (Crotalus horridus) was designated Extirpated by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2001 and was officially listed under the Species at Risk Act (SARA) in June 2003. SARA (Section 37) requires the competent Minister to prepare a recovery strategy for all listed extirpated, endangered, or threatened species. The Canadian Wildlife Service - Ontario, Environment Canada, led the development of this recovery strategy, and it was developed in cooperation with the Government of Ontario. All responsible jurisdictions reviewed and acknowledged receipt of this strategy. The strategy meets SARA requirements in terms of content and process (Sections 39-41).

A 50 kDa protein that inhibits platelet adhesion to collagen has been isolated from snake venom of Crotalus atrox (western diamondback rattlesnake) and has been named catrocollastatin. The cDNA cloning of catrocollastatin has been accomplished. A full-length cDNA of 2310 bp with an open reading frame between nucleotides 51 and 1880 was obtained. The deduced amino acid sequence consists of 609 amino acids. The cDNA-predicted amino acid sequence is highly similar to that of haemorrhagic metalloproteinase jararhagin from Bothrops jararaca venom, HR1B from Trimeresurus flavoviridis, Ht-e from C. atrox and trigramin from T. gramineus. Like jararhagin and HR1B, catrocollastatin is a multidomain molecule composed of an N-terminal domain, a metalloproteinase domain, a disintegrin-like domain and a cysteine-rich C-terminal domain. In the disintegrin-like domain, the frequently seen RGD (Arg-Gly-Asp) sequence is replaced by SECD (Ser-Glu-Cys-Asp). This cDNA was expressed in Spodoptera frugiperda (fall ...
TY - JOUR. T1 - Iron and carbon monoxide prevent degradation of plasmatic coagulation by thrombin-like activity in rattlesnake venom. AU - Nielsen, Vance G. PY - 2016/10/1. Y1 - 2016/10/1. N2 - Thousands suffer poisonous snake bite, often from defibrinogenating species annually. Three rattlesnake species in particular, the timber rattlesnake, Eastern diamondback rattlesnake, and Southern Pacific rattlesnake, cause clinically relevant hypofibrinogenemia via thrombin-like activity in their venom. It has been demonstrated that iron (Fe) and carbon monoxide (CO) change the ultrastructure of plasma thrombi and improve coagulation kinetics. Thus, the present investigation sought to determine if pretreatment of plasma with Fe and CO could attenuate venom-mediated catalysis of fibrinogen via thrombin-like activity. Human plasma was pretreated with ferric chloride (0-10 μM) and CO-releasing molecule-2 (0-100 μM) prior to exposure to 2.5-10 μg/ml of venom obtained from the aforementioned three species ...

Nine of the 17 venoms here tested were found capable of coagulating citrated blood or plasma. As has been believed by most workers in the field, 7 of these 9 coagulant venoms convert fibrinogen to an insoluble modification resembling fibrin (Bothrops atrox, Bothrops jararaca, Bothrops nummifera, Crotalus adamanteus, Crotalus horridus, Crotalus terrificus basiliscus, Crotalus terrificus terrificus). The optimum pH for this coagulation was determined for 3 of these, and was found in each case to be approximately pH 6.5, the same as that for the action of thrombin on fibrinogen. Unlike thrombin, however, the fibrinogen-coagulating activity of the venoms was unaffected by the antithrombin elaborated in the course of anaphylactic shock.. In addition to coagulating fibrinogen directly, 3 of these venoms (Bothrops atrox, Bothrops jararaca, and to a less extent, Crotalus terrificus basiliscus) acted on prothrombin to convert it to thrombin, without the necessary intervention of either calcium or ...
In this work we have characterized the action of the naringin, a flavonoid found in grapefruit and known for its various pharmacological effects, which include antioxidant blood lipid lowering and anticancer activity, on the structure and biochemical activities of a secretory phospholipase A (sPLA2) from Crotalus durissus cascavella, an important protein involved in the releasinge of arachidonic acid in phospholipid membranes. sPLA2 was incubated with naringin (mol:mol) at 37 °C and a discrete reduction in the UV scanning signal and a modification of the circular dichroism spectra were observed after treatment with naringin, suggesting modifications of the secondary structure of the protein. This flavonoid was able to decrease enzymatic activity and some pharmacological effects, such as myonecrosis, platelet aggregation, and neurotoxic activity caused by sPLA2, however, the inflammatory effect was not affected by naringin. In addition, small angle X-ray scattering (SAXS) data were collected for sPLA2

All animals face the risk of periods of food deprivation, which can lead to starvation and ultimately death. Most animals, especially mammals, are not well adapted to withstand food deprivation and extended periods of starvation. But some animals, such as penguins and ground squirrels, have developed strategies that enable them to survive multiple months without food. Snakes, however, are in a league of their own in their ability to deal with food limitation and can endure multiple years of starvation. Although this has been known for a long time, very little is known about the underlying biological mechanisms. To investigate this stunning phenomenon, Marshall D. McCue from the University of Arkansas, USA, examined changes in physiology, morphology and body composition in response to 168 days of starvation in three species of snakes: the ball python (Python regius), the ratsnake (Elaphe obsolete) and the western diamondback rattlesnake (Crotalus atrox).. It is not a simple task to define when ...
A hiker remained hospitalized Tuesday after receiving a rare rattlesnake bite while he was hiking in southeastern Minnesota, officials said. The 28-year-old Mounds View man was in fair condition Tuesday at Gundersen Lutheran Health System in La Crosse, Wis., where he was taken by ambulance Friday after being bitten by a timber rattlesnake in Beaver Creek Valley State Park near Caledonia, known habitat for the venomous snake. The man, who declined to be interviewed, was recovering from what appears to be an extremely rare event: a timber rattlesnake striking out at a human without provocation. Nobody knows what provoked the strike, said Ed Quinn, a wildlife biologist and coordinator of natural resource management for parks and trails with the Minnesota Department of Natural Resources. Its just really rare for this to happen. The last known time a timber rattler bit a person in Minnesota was 2000; the last time one bit without provocation was 1996. The last known fatality in Minnesota from a ...

Antivenin activity of melanin extracted from black tea (MEBT) was reported for the first time. The antagonistic effect of MEBT was evaluated for Agkistrodon contortrix laticinctus (broadbanded copperhead), Agkistrodon halys blomhoffii (Japanese mamushi), and Crotalus atrox (western diamondback rattlesnake) snake venoms administered i.p. to ICR mice. MEBT was injected i.p. immediately after the venom administration in dose of 3 mg per mouse in the same place of venom injection. MEBT demonstrated neutralization effect against all venoms tested. The greatest antivenin effect of MEBT was found against Japanese mamushi snake venom. In this case, half the mice died within 2.5 +/- 0.7 h after injection of 0.9 mg/kg of venom. An immediate injection of MEBT substantially reduced the toxic effect of venom and extended time at the 50% level of survival up to 52.3 +/- 2.3 h. The antivenin activity of MEBT is due to chelating of Ca++ and non-specific binding of phospholipase A2. The inhibitory effe

TUCSON - As soon as a rattlesnake sinks its fangs into a victim, the venom starts traveling through the bloodstream. Within seconds, people can experience pain, swelling, bleeding and trouble breathing.. Its a race against time to get to a hospital, the only place that readily offers anti-venom. The longer it takes to get treatment, the higher the odds of long-term injury or death.. One University of Arizona doctor hopes to buy people more time before they get to the hospital.. Professor Vance Nielsen, the vice chair for research in the Department of Anesthesiology at the College of Medicine - Tucson, said his research could help stall the spread of rattlesnake venom through the body.. Nielsen is researching the potential of injecting a combination of carbon monoxide and iron in a rattlesnake bite area to slow the spread of venom. So far, he has made progress in rabbits, buying about an hour of time.. The idea is not to replace anti-venom, but extend the time patients have until they can get to ...
They are commonly found in rock and debris piles, animal burrows and crevices. They will seek out roads, open sandy areas and rocks to sun themselves during cooler temperatures.. They are more active in spring and summer. But it is important to remember you can encounter rattlesnakes anytime and anywhere. Rattlesnakes prey on mice and other small rodents. They dont lay eggs, but rather give live birth to young snakes about 9 to 12 inches long.. Like other snakes, mammals and birds, rattlesnakes fill an important place in the ecosystem by preying on rodents and keeping their populations in balance. When the rattlesnake is found in a backyard, this ecological role may not seem so apparent or important.. Other snakes such as the gopher snake, red racer and king snake are common on Edwards. Many people kill gopher snakes confusing their tan coloration and indistinct black markings for a rattlesnake.. Gopher snakes, red racers and other snakes often hiss and shake their tails imitating the motion ...
The B-chain of the acidic subunit of crotoxin proved refractory to Edman degradation. When subjected to sequence analysis using tandem mass spectrometry, pyroglutamate was found at the amino-terminal end, even though earlier attempts to de-block with pyroglutamate aminopeptidase were unsuccessful. The B-chain contained 35 amino acids and showed 91% amino acid identity with the corresponding segment from Mojave toxin, a homologous neurotoxin from Crotalus scutulatus scutulatus. The sequence of the last 24 residues of the B-chain is consistent with that previously published (Aird, S.D., Kaiser, I.I., Lewis, R.V. and Kruggel, W.G. (1985) Biochemistry 24, 7054-7058), except at position 20, where Edman degradation gave glycine and mass spectrometry gave glutamic acid ...
Resumo: Venenos de serpentes constituem uma rica fonte de moléculas biologicamente ativas capazes de atuar em alvos celulares específicos e modular uma distinta variedade de funções fisiológicas. Fosfolipases A2 homólogas Lys49 são abundantes proteínas presentes nessas complexas secreções, que embora cataliticamente inativas, desempenham uma ampla gama de atividades, tais como: miotoxicidade, citotoxicidade, atividade antibacteriana, antifúngica, entre outras. O veneno de Crotalus oreganus abyssus não tem sido muito estudado, portanto, a caracterização de seus componentes representa uma ferramenta biotecnológica valiosa para o estudo dos eventos fisiopatológicos do envenenamento e para uma melhor compreensão de seus efeitos biológicos. No presente trabalho, uma fosfolipase A2 homóloga Lys49, denominada CoaTx-II, do veneno de Crotalus oreganus abyssus foi purificada e caracterizada estrutural e farmacologicamente. CoaTx-II foi isolada com elevado grau de pureza através da ...

Understanding the processes that drive the evolution of snake venom is a topic of great research interest in molecular and evolutionary toxinology. Recent studies suggest that ontogenetic changes in venom composition are genetically controlled rather than environmentally induced. However, the molecular mechanisms underlying these changes remain elusive. Here we have explored the basis and level of regulation of the ontogenetic shift in the venom composition of the Central American rattlesnake, Crotalus s. simus using a combined proteomics and transcriptomics approach. Proteomic analysis showed that the ontogenetic shift in the venom composition of C. s. simus is essentially characterized by a gradual reduction in the expression of serine proteinases and PLA2 molecules, particularly crotoxin, a β-neurotoxic heterodimeric PLA2, concominantly with an increment of PI and PIII metalloproteinases at age 9-18 months. Comparison of the transcriptional activity of the venom glands of neonate and adult C. s.
By Katie Bauer - bio , email. LUBBOCK, TX (KCBD) - Several people have left comments on our Facebook page, saying theyve seen more snakes on the South Plains since the July 4th weekend floods. One Tahoka woman is just glad her father is alive after being bitten by a rattlesnake multiple times.. Penny Redman said she always knew her dad was a fighter. Hes been a real trooper, hes a tough man, said Redman.. A couple of weeks ago, 87-year-old Pug Parker of Tahoka went outside to get something out of a toolbox. Hes diabetic so his vision is very poor, he reached in with his left hand because he cant see, feeling for a screw and evidently there was a mom and some babies, said Redman.. Parker was bitten ten times. Baby rattlesnake bites are more venomous than adult rattlesnakes. They dont know how to stop releasing the venom. They release all they have. Adults can judge how much they want to release, said Redman. Parker was rushed by AeroCare to Covenant Hospital, and on the way to the ...
Gyroxin is a glycoprotein isolated from rattlesnake venom, with known thrombin-like serine protease properties and behavioral action in the CNS. The mechanism of the latter has eluded experimenters for three decades. In this paper about the in vitro chick retina we demonstrate an excitotoxic CNS action of Gyroxin by observing retinal Intrinsic Optical Signals (IOS). These show sudden dynamic changes in the intact tissue due to gyroxin action. The very fast kinetics of this response precludes deep tissue penetration by the protein, a mechanism of tissue response described here for the first time. At nanomolar concentrations, Gyroxin alters profoundly the optical profiles of retinal spreading depression waves (RSDs), suggesting modulation of ionic transport and metabolism. This effect is reversible in contrast with the acute cell lysis induced with gyroxin pulses at higher concentration. Because there may be more than one target of Gyroxine at the retinal inner limiting membrane, additional ...

Abstract The hemolytic activities of the venom of Agkistrodon contortrix mokeson, Agkistrodon piscivorus leucostoma, Crotalus atrox, and Crotalus scutulatus were studied by using hypotonic solutions. The effects with whole venoms plus lecithin were compared with effects caused by boiled venom supernatant fluids containing phospholipase A and lecithin to gain insight into the role of heat-labile venom components on lysing human red blood cells. Phospholipase A in the supernatant fluids of all venoms with lecithin caused stabilization of red-blood-cell membranes. A. c. mokeson, A. p. leucostoma, and C. scutulatus whole venoms demonstrated a specific lytic behavior, whereas C. atrox whole venom demonstrated a nonspecific lytic behavior. Heparin altered the lytic behavior of C. scutulatus whole venom but did not influence the other venoms.

In a fight between a kangaroo rat and a rattlesnake, maybe bet on the rat, according to new research out of California. High-speed video captured by researchers at the University of California Riverside show the small rodents, that often weigh just 4.5 ounces, can kick an attacking rattlesnake in the head with lightning-fast speed, ninja-style. In one video, a rat is seen jumping high in the air and kicking a snake with its haunches, launching the serpent several feet away. Then, the rat runs off to safety. Kangaroo rats that responded quickly were frequently able to jump clear of the snake completely, leaving the serpent biting nothing but dust as the kangaroo rat rocketed 7-8 body lengths into the air, Rulon Clark, coauthor and an associate professor of biology at San Diego State University, said in a statement. The team has been working to figure out how the rats evade death when snakes attack for some time. This week, they published two new papers in peer-reviewed journals Functional ...

Most creatures faces have the same standard arrangement of features; eyes at the top, nose beneath and mouth at the bottom. But pitvipers carry an extra set of facial indentations: facial pits. Staring into the dark hollows of these depressions, an age-old question glares back: what are they for? With thermally sensitive nerve endings concentrated in the pits, these organs respond to radiant heat, and allow snakes to detect and capture prey. But Aaron Krochmal thinks that this simple explanation could have distracted people from exploring alternative functions for the pits. Could they be involved in thermoregulation? Cold-blooded animals exploit their environment to regulate their body temperatures; they seek cool spots to escape the heat or warm places when its cold. But little was known about the sensory cues that guide this behavior. Krochmal wondered whether the snakes might use their facial pits to direct them towards the sanctuary of a cool burrow (p. 2539).. Western diamondback ...

Advocates for increasing state oversight of rattlesnake roundups in Texas received disappointing news this week when the Texas Parks and Wildlife Commission decided that they would not support a proposed ban on using gasoline fumes to collect rattlesnakes. Rather than reviewing and voting on the issue at their bi-annual meeting next month, the TPW Commission decided to remove it from their agenda entirely, citing insufficient support from legislative oversight or the potentially regulated community. This decision marks the second time reviewing the ban has been put off, and unfortunately it is likely to be the last until the effort to reform roundups is re-initiated.

This undeniable pushing-back of the frontiers of science comes to us courtesy of Professor Daniel Goldmans Complex Rheology And Biomechanics Lab (the Crab Lab) at the Georgia Institute of Technology in the US.. Goldman and his Crabby colleagues were determined to find out just how it is that the enigmatic sidewinder rattlesnakes of America manage to squirm their way up slippery sand dunes, a notoriously tricky form of terrain to get about on - and which leaves other snakes baffled.. After a good deal of investigation, which involved painting reflective spots on some surprisingly cooperative rattlesnakes and videoing them in action, the good prof and his Crabs managed to crack the sidewinders methods. They proved this by applying them to snakey robots furnished by colleagues at the famous mad-robot labs of Carnegie Mellon university, pictured above. The basic robot, as shown, is clad in a textile wrapping or trouser in order to keep sand out of its works - in much the same fashion as ...
Australia is not only home to venomous snakes, spiders and jellyfish, now scientists have discovered that its lizards are venomous too.. For instance little bearded dragon lizards that cruise around the suburbs have classic rattlesnake venom, scientists report in the journal Nature.. But the venom is not dangerous to humans, Dr Bryan Fry from the University of Melbournes Australian Venom Research Unit says, who led the international research team.. The lizards do not produce enough venom and what little they do is used to kill prey.. Dr Fry spent months in the Australian desert and tropics capturing, studying and milking dozens of lizards.. He and his colleagues then studied their toxins, DNA and evolution.. The researchers discovered that two common lizard lineages found in Australia, monitor lizards and iguania, have mouth glands that secrete venom toxins.. This was surprising as until now scientists had only found two lizard species around the world that produced venom, the gila monster and ...

The Hydragen is a huge, mutated descendant of the diamond-backed rattlesnake. It is found in many places in the deserts of southwest North American (the old United States and Mexico). Hydragens range from 50-65 in length in adulthood and appear to be large, multiple-headed serpents; 2-7 heads are present and each is well equipped with razor-sharp fangs and teeth. The six major fangs, in the upper jaws along the front, contain class 11 poison effective only against mammalian creatures (including humans, of course).

The Hydragen is a huge, mutated descendant of the diamond-backed rattlesnake. It is found in many places in the deserts of southwest North American (the old United States and Mexico). Hydragens range from 50-65 in length in adulthood and appear to be large, multiple-headed serpents; 2-7 heads are present and each is well equipped with razor-sharp fangs and teeth. The six major fangs, in the upper jaws along the front, contain class 11 poison effective only against mammalian creatures (including humans, of course). Because of their speed, these monsters rarely go hungry, although relatively intelligent beings give them a wide berth. They are not especially intelligent themselves, but Hydragens readily pursue any prey and use their cunning to drive victims into dead-ends (box canyons and the like) to prevent escape ...

After two weeks at U.S. Marine survival training came the POW phase designed specifically to make prisoners break.. A guard at the compound slapped me across the face. You will break.. Not before your mother ends up in a whorehouse.. That was the beginning. Constant torture: water boarding; mice in a cage over your head; strung up naked and beaten. . .. Some men broke, it was that realistic.. We have ways of discovering your greatest fear and using it to release you from your mental prison, an enemy interrogator promised.. Guards stripped me in the middle of the night and confined me inside a wooden crate so small that my body folded nearly double. I could only move my hands from the wrists down.. I felt ropes, or something like ropes, only ropes that moved, dropping onto my bare skin. A musky odor.. Dont even breathe hard, a guard warned. They are rattlesnakes.. I felt scales contorting and releasing as the snake sought purchase on my bare skin. Maybe seven or eight snakes. ...

Why is it a bad idea to get bitten by a rattlesnake, stung by a scorpion or to eat lead paint chips? In this talk, designed to be accessible to a broad audience, Dr. Currie will use images animations and demonstrations (but no animals) to illustrate how nerve cells work and how investigating the action of toxins can help scientists get a better grasp on normal nervous system function and on what happens when neurons are exposed to toxins.. Admission by donation.. Call 207-780-4249 or e-mail [email protected] to reserve your space or to obtain more information.. ...
The animation is breathtaking. Every fur texture, the hair, the scales, the clothes, all are perfect. The facial expressions and gaits are wonderful, naturalistic when called for and properly exaggerated when needed - for instance when Bill Nighys sinister Rattlesnake Jake decides to crush someone in his coils. The landscapes are fine, and the lighting is so good that it genuinely looked as though someone had built and lit the sets for a master DP. On the other hand, the movie featured so much sudden death, mutilation, injury, roadkill, impaling on cactus spines, being set on fire, guns being handled by children and loss-of-eye-due-to-arrow-through-socket that it made me actually uncomfortable ...

Wrote Shea Bennett (@Sheamus) on Twitter: Im British. Ive lived in the UK all my life. Had no idea you could do this with our coins. Did you?. Apparently not as he noted his tweet featuring the coins (top) had been retweeted 2,700 times (as of six hours ago).. Well, my British homies?. What say you?. The reason stuff like this enchants me is that not only is it in and of itself fascinating but also the fact that something so interesting can exist completely unremarked for so long by so many implies an entire universe bursting with unknown wonders - if only we can figure out a way to routinely step back from our normal acceptance of the world as it is to appreciate just how much more is right there in front of us, patiently biding its time, waiting to be grasped and embraced.. [via Rattlesnake Jake]. ...
The other people dont count. They are not worth muddying the waters with, they are all entertaining, disreputable, and about as much fun as a sack full of rattlesnakes, but they make the story more complex that it needs to be.. I am going to remove Crystal from the equation, her $12,000 motive (back child support) holds no water. I also seriously doubt that she has the capacity to plan a crime like this, never mind carry it out!. Lets take a look at Cousin Joe. There are some things in his background that do seem to indicate that this might be his kind of gig. However reality says that he makes a great scapegoat rather than perpetrator. I have no inside track with the PCSO, they are always polite to me, and they always respond in a prompt and professional manner to my questions so this is pure guesswork on my behalf. The one thing that I do know for sure is that if they thought Cousin Joe was involved, he would be cooling his heels in jail right now. He is not Mr. Clean, it would be easy to ...
