Cloning, expression and biochemical characterization of a basic-acidic hybrid phospholipase A2-II from Agkistrodon halys pallas. (1/68)

A cDNA encoding a basic-acidic hybrid phospholipase A2-II from Agkistrodon halys Pallas with an N-terminus highly homologous to that of BPLA2 and a C-terminus sequence almost the same as that of APLA2 was inserted into a bacterial expression vector and effectively expressed in Escherichia coli RR1. The protein was produced as insoluble inclusion bodies. After partial purification by washing, the inclusion bodies with Triton X-100, denaturing and refolding, the renatured recombinant protein was purified by FPLC column superose 12. The purified recombinant enzyme with an isoelectric point of pH 6.8 could cross-react with antiserum prepared against acidic phospholipase A2. The enzymatic activity of the expressed basic-acidic hybrid phospholipase A2-II is close to that of denatured-refolded native basic phospholipase A2, and has the same inhibiting effect on platelet aggregation as denatured-refolded acidic phospholipase A2, but lacks the hemolytic activity of denatured-refolded basic phospholipase A2. To study the structural relationships among basic phospholipase A2, acidic phospholipase A2 and basic-acidic hybrid phospholipase A2-II, molecular modeling of basic-acidic hybrid phospholipase A2-II was done. The roles of various amino acid residues in the enzymatic activity and pharmacological activities of phospholipase A2 are discussed.  (+info)

cDNA cloning and bacterial expression of phospholipase A(2) inhibitor PLIalpha from the serum of the Chinese mamushi, Agkistrodon blomhoffii siniticus(1). (2/68)

The cDNA encoding of a phospholipase A(2) inhibitor (PLIalpha) of the Chinese mamushi, Agkistrodon blomhoffii siniticus, was identified from a liver cDNA library by use of a probe prepared by polymerase chain reaction (PCR) on the basis of the amino acid sequence of PLIalpha. It encoded a polypeptide of 166 amino acid residues, including 19 residues of the signal sequence and 147 residues of the complete mature sequence of PLIalpha. The PLIalpha cDNA was subcloned into the expression vector pET-16b and used to transform Escherichia coli strain BL21(DE3)pLysS. The recombinant PLIalpha expressed as a fusion protein was solubilized and purified to homogeneity by use of a metal affinity resin. The purified PLIalpha fusion protein underwent folding to form a trimeric structure like the intact PLIalpha, and showed inhibitory activity against the group II acidic PLA(2) from A. blomhoffii siniticus venom; although its binding constant (1/K(i)) value was 30-fold lower than that of the natural PLIalpha. The elimination of the N-terminal additional peptide from the fusion protein resulted in a marked increase in the inhibition activity with a binding constant comparable to that of the natural PLIalpha against the acidic PLA(2). Furthermore, the carbohydrate chains of the natural PLIalpha were found to play an important role in the inhibitory activity against the basic PLA(2).  (+info)

Purification, cloning and sequence analyses for pro-metalloprotease-disintegrin variants from Deinagkistrodon acutus venom and subclassification of the small venom metalloproteases. (3/68)

Acidic and basic hemorrhagic metalloproteases were purified from the venom of Deinagkistrodon acutus (from Fujian Province, China) using gel filtration and anion exchange on FPLC and reversed-phase HPLC. Their hemorrhagic activities and N-terminal sequences were characterized. Extensive screening of the venom gland cDNA after PCR amplification resulted in the identification and sequencing of a total of seven cDNA clones encoding the multidomain precursors of six acidic and one alkaline low molecular mass metalloproteases. Two of the precursors contain a processable disintegrin domain. Disintegrins of 5 kDa were also purified from the venom. The partial amino-acid sequences and molecular masses determined by electrospray ionization mass spectrometry of the purified proteins specifically match those deduced from two of the cDNA sequences. Moreover, phylogenetic analyses based on 30 complete sequences of low molecular mass venom metalloproteases revealed that they may be classified into three functional subtypes: acidic hemorrhagins, basic and moderate hemorrhagins, and nonhemorrhagic enzymes. Subtype-specific amino-acid substitutions in the C-terminal regions of the enzymes were highlighted to explore the structure-activity relationships of the enzymes.  (+info)

Characterization and cDNA cloning of a platelet aggregation inhibitor. (4/68)

A novel platelet aggregation inhibitor, sal-C, was purified to homogeneity from the venom of Korean snake (Agkistrodon halys brevicaudus). Several lines of experimental evidence clearly indicated that sal-C inhibits not only the collagen-induced platelet aggregation, but also the aggregation mediated by the cell surface glycoprotein IIb-IIIa (GP IIb-IIIa). We have isolated the cDNA encoding sal-C from the cDNA library of the snake venom gland and analyzed its complete nucleotide sequence. Sal-C is a single-chain polypeptide composed of 212 amino acids including 24 cysteines. The deduced polypeptide sequence of sal-C demonstrated considerable homology to previously described protein species of the collagen-induced platelet aggregation inhibitor family. Sal-C does not have the Arg-Gly-Asp (RGD) motif, but contains the Ser-Glu-Cys-Asp sequence. Interestingly, sal-C was found to inhibit GP IIb-IIIa binding to immobilized fibrinogen which is antagonized by the typical RGD motif of disintegrins.  (+info)

Ultrastructure of the capillary pericytes and the expression of smooth muscle alpha-actin and desmin in the snake infrared sensory organs. (5/68)

The infrared sensory membranes of pit organs of pit vipers have an extremely rich capillary vasculature that forms many vascular loops, each serving a small number of infrared nerve terminals. We clarified the ultrastructure of capillary pericytes in the pit membranes by scanning and transmission electron microscopy, and examined the immunoreactivity in their cytoplasm to two contractile proteins: smooth muscle alpha-actin (SM alpha-actin) and desmin. The capillary pericytes had two major cytoplasmic processes: thickened primary processes that radiate to embrace the endothelial tube and flattened secondary processes that are distributed widely on the endothelium. Coexpression of SM alpha-actin and desmin was observed in the pericytes of entire capillary segments, and SM alpha-actin was characterized by prominent filament bundles directed mainly at right angles to the capillary long axis. This expression pattern was different from that of capillary pericytes of the scales, where SM alpha-actin was expressed diffusely in the cytoplasm. In a series of electron microscopic sections, we often observed the pericyte processes depressing the endothelial wall. We also observed a close relationship of the pericytes with inter-endothelial cell junctions, and pericyte processes connected with the endothelial cells via gap junctions. From these findings, we surmised that capillary pericytes in the pit membrane have a close functional relationship with the endothelium, and through their contractile and relaxing activity regulate capillary bloodflow to stabilize production of infrared nerve impulses.  (+info)

Toward understanding interfacial activation of secretory phospholipase A2 (PLA2): membrane surface properties and membrane-induced structural changes in the enzyme contribute synergistically to PLA2 activation. (6/68)

Phospholipase A2 (PLA2) hydrolyzes phospholipids to free fatty acids and lysolipids and thus initiates the biosynthesis of eicosanoids and platelet-activating factor, potent mediators of inflammation, allergy, apoptosis, and tumorigenesis. The relative contributions of the physical properties of membranes and the structural changes in PLA2 to the interfacial activation of PLA2, that is, a strong increase in the lipolytic activity upon binding to the surface of phospholipid membranes or micelles, are not well understood. The present results demonstrate that both binding of PLA2 to phospholipid bilayers and its activity are facilitated by membrane surface electrostatics. Higher PLA2 activity toward negatively charged membranes is shown to result from stronger membrane-enzyme electrostatic interactions rather than selective hydrolysis of the acidic lipid. Phospholipid hydrolysis by PLA2 is followed by preferential removal of the liberated lysolipid and accumulation of the fatty acid in the membrane that may predominantly modulate PLA2 activity by affecting membrane electrostatics and/or morphology. The previously described induction of a flexible helical structure in PLA2 during interfacial activation was more pronounced at higher negative charge densities of membranes. These findings identify a reciprocal relationship between the membrane surface properties, strength of membrane binding of PLA2, membrane-induced structural changes in PLA2, and the enzyme activation.  (+info)

Serine protease isoforms of Deinagkistrodon acutus venom: cloning, sequencing and phylogenetic analysis. (7/68)

The major coagulating fibrinogenase of Deinagkistrdon acutus venom, designated acutobin, was purified by anion-exchange chromatography, gel filtration and reverse-phase HPLC. Approximately 80% of its protein sequence was determined by sequencing the various fragments derived from CNBr cleavage and digestion with endoprotease. Extensive screening of the venom gland cDNA species after amplification by PCR resulted in the isolation of four distinct cDNA clones encoding acutobin and three other serine proteases, designated Dav-PA, Dav-KN and Dav-X. The complete amino acid sequences of these enzymes were deduced from the cDNA sequences. The amino-acid sequence of acutobin contains a single chain of 236 residues including four potential N-glycosylation sites. The purified acutobin (40 kDa) contains approx. 30% carbohydrate by weight, which could be partly removed by N-glycanase. The phylogenetic tree of the complete amino acid sequences of 40 serine proteases from 18 species of Crotalinae shows functional clusters reflecting parallel evolution of the three major venom enzyme subtypes: coagulating enzymes, kininogenases and plasminogen activators. The possible structural elements responsible for the functional specificity of each subtype are discussed.  (+info)

Aggretin, a heterodimeric C-type lectin from Calloselasma rhodostoma (Malayan pit viper), stimulates platelets by binding to alpha2beta1 integrin and glycoprotein Ib, activating Syk and phospholipase Cgamma 2, but does not involve the glycoprotein VI/Fc receptor gamma chain collagen receptor. (8/68)

Aggretin, a potent platelet activator, was isolated from Calloselasma rhodostoma venom, and 30-amino acid N-terminal sequences of both subunits were determined. Aggretin belongs to the heterodimeric snake C-type lectin family and is thought to activate platelets by binding to platelet glycoprotein alpha(2)beta(1). We now show that binding to glycoprotein (GP) Ib is also required. Aggretin-induced platelet activation was inhibited by a monoclonal antibody to GPIb as well as by antibodies to alpha(2)beta(1). Binding of both of these platelet receptors to aggretin was confirmed by affinity chromatography. No binding of other major platelet membrane glycoproteins, in particular GPVI, to aggretin was detected. Aggretin also activates platelets from Fc receptor gamma chain (Fcgamma)-deficient mice to a greater extent than those from normal control mice, showing that it does not use the GPVI/Fcgamma pathway. Platelets from Fcgamma-deficient mice expressed fibrinogen receptors normally in response to collagen, although they did not aggregate, indicating that these platelets may partly compensate via other receptors including alpha(2)beta(1) or GPIb for the lack of the Fcgamma pathway. Signaling by aggretin involves a dose-dependent lag phase followed by rapid tyrosine phosphorylation of a number of proteins. Among these are p72(SYK), p125(FAK), and PLCgamma2, whereas, in comparison with collagen and convulxin, the Fcgamma subunit neither is phosphorylated nor coprecipitates with p72(SYK). This supports an independent, GPIb- and integrin-based pathway for activation of p72(SYK) not involving the Fcgamma receptor.  (+info)

The venom of D. acutus, a snake endemic to China, possess proteins and peptides whose activity is mainly hemotoxic [28]. At the bite site, swelling, bruising, blistering and necrosis usually develop within a few minutes or hours and spread rapidly, sometimes the whole limb is affected [6]. The persistent bleeding from the fang marks and other previous partially healed wounds indicates coagulopathy, which is caused by the abundant metalloproteinases and serine proteases of D. acutus venom [5, 6]. Its toxicity and pathophysiologic effects can be completely reversed by specific antivenom, which is conventionally produced from blood of large animals (horses or sheep) immunized with snake venoms [8, 10]. As an alternative to the conventional antivenom with various side effects and the disadvantages of its preparation and production, antivenom IgY antibodies from egg yolk of chicken have considerable advantages [8, 16, 29]. Previous studies have shown that chicken immunized with snake venom produces ...
The major coagulating fibrinogenase of Deinagkistrdon acutus venom, designated acutobin, was purified by anion-exchange chromatography, gel filtration and reverse-phase HPLC. Approximately 80% of its protein sequence was determined by sequencing the various fragments derived from CNBr cleavage and digestion with endoprotease. Extensive screening of the venom gland cDNA species after amplification by PCR resulted in the isolation of four distinct cDNA clones encoding acutobin and three other serine proteases, designated Dav-PA, Dav-KN and Dav-X. The complete amino acid sequences of these enzymes were deduced from the cDNA sequences. The amino-acid sequence of acutobin contains a single chain of 236 residues including four potential N-glycosylation sites. The purified acutobin (40kDa) contains approx. 30% carbohydrate by weight, which could be partly removed by N-glycanase. The phylogenetic tree of the complete amino acid sequences of 40 serine proteases from 18 species of Crotalinae shows ...

The Trans-Pecos copperhead (A. contortrix pictigaster) is similar to the Broad-banded, is of equal size, and has slightly hourglass-shaped markings, usually with a lighter patch at the base of each band. The genus Agkistrodon, of which the American copperhead is a member, includes 10 species, three of them native to North America (one being the well-known Cottonmouth. The rest can be found in Asia and the islands nearby - notable members include the Siberian moccasin, the Himalayan viper, and the Okinawan habu. Note that the three Australian copperheads are elapids and not related.. American copperheads breed in late summer but not to a fixed pattern: sometimes a female will give produce young for several years running, then not breed at all for a time. They give birth to live young about 20 cm long: a typical litter is 4 to 7, but it can be as few as 1 or as many as 20. Other than size, the young are similar to the adults, but lighter in color, and with a yellow-marked tip to the tail, which is ...
Some people ask this question when they see a snake in the water. Unfortunately, many people assume all snakes in the water are cottonmouths and kill them "just in case." Along with sharks and bats, snakes are among the most misunderstood and mistreated animals on earth. Yes, some species of snakes, including the cottonmouth (Agkistrodon piscivorus), also known as the water moccasin, are venomous and therefore a potential danger. However, of the 32 snake species native to Tennessee, only 4 are venomous all others are completely harmless. Among the 28 harmless nonvenomous snakes, water snakes (Nerodia and Regina species) and eastern hognose snakes (Heterodon platirhinos) are often unfortunate victims of mistaken identity thought to be cottonmouths. This brochure was developed to highlight the differences between water snakes, hognose snakes, and cottonmouths with the hope that familiarity with these snakes will prevent further unnecessary killing of snakes. ...
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 this study, a modified on-column frit preparation method for fused silica capillaries was used to analyze a venom mixture which contained the milkings from approximately ten snakes of the Agkistrodon contortrix contortrix (southern copperhead) species. One hundred and twenty-three proteins were identified by in-gel digestion coupled with nano-HPLC MS. Among them, twenty proteins matched the references and databases identified as snake venom proteins. In addition, de novo sequencing is applied to analyze the collision-induced dissociation (CID) data generated by in-solution digestion coupled with nano-HPLC MS. Twenty-three proteins matched the databases and references previously identified as snake venom proteins.; Because of insufficient sequences in the database, many peptides and hypothetical proteins could not be matched to the venom proteins. Some venom proteins we identified were found in other species. To build up an intact knowledge base to help toxicant study and clinical treatment, ...

The snake has been given a bad reputation over the years as a very aggressive snake that will attack anything nearby. When tested to measure the different responses of the cottonmouth to encounters with humans, 23 of 45 (51%) tried to escape while 28 of 36 (78%) resorted to threat displays and other defensive tactics. It was only when they were picked up with a mechanical hand were they likely to bite (4). The characteristic threat display that has earned the cottonmouth its name includes throwing its head back with its jaws open to show the white lining of the mouth. The tail vibrates, much like other vipers like rattlesnakes, and the head and body are curled into an S-shape, appearing as though the snake is waiting to strike. The snake is most likely to stand its ground and resort to these most common threat displays which has often been mistaken for aggressive behavior (1). The cottonmouth can be active during the day or the night. Usually during the night. They bask during the day. They are ...

Another effect of neurotoxic venom is necrosis. If youre wondering what the word "necrosis" means, it basically means the killing of tissue cells which leads to skin and muscle tissue literally rotting around the bite wound. That necrosis often leads to amputation. The effects of this neurotoxic venom often has a lasting effect on the bodys extremities. There are a few native venomous snakes here in the United States with neurotoxic venom like for example the mojave rattlesnake, tiger rattlesnake, southern pacific rattlesnake, canebrake rattlesnake and the coral snake. Throughout the globe, there are many different species of venomous snakes that are equipped with neurotoxic venom and for the most part theyre mainly elapids like cobras, mambas, tiapans etc..

Agkistrodon is a genus of venomous pit vipers found in North America from the United States south to northern Costa Rica. Three species are currently recognized, all of them polytypic and closely related. Common names include: cottonmouths, copperheads, cantils. Some varieties are known as "moccasins" or "moccasin snakes", such as Agkistrodon piscivorus, the water moccasin. The name Agkistrodon comes from the Greek words agkistron (ἄγκιστρον, fishhook, with the irregular transliteration gk rather than the usual nk) and odous (ὁδοὐς, tooth, from the stem ὁδόντ-) and is likely a reference to the fangs. Some varieties of the genus are given the common name "moccasin" or "moccasin snake" in the United States, which is the Algonquian word for "shoe". The origin of this nickname are unknown. The first known use of "moccasin" to refer to a deadly venomous snake was in a 1765 publication. The nickname is used to refer to both cottonmouths and copperheads. According to the Word ...
Agkistrodon piscivorus es una serpiente venenosa, una especie de crótalo, que habita en el sur este de Estados Unidos. Los adultos son grandes y capaces de producir una mordida dolorosa y potencialmente fatal. Si se las enfrenta, se defienden enrollando sus cuerpos y exhibiendo sus colmillos.[2]​ Aunque su capacidad de agresión ha sido exagerada, en rara ocasión los machos territoriales se acercan a los intrusos de manera agresiva.[3]​ Esta es el único crótalo semiacuático del mundo, por lo general se la encuentra en o cerca del agua, particularmente en lagos poco profundos y con poco movimiento, arroyos y marismas. Esta serpiente es muy buena nadadora y a veces inclusive se adentra en el mar, colonizando con éxito islas frente a las costas del Atlántico y del Golfo de México. Su nombre científico deriva de las palabras griegas ancistro (anzuelo) y odon (diente), y el nombre de la especie proviene del latín piscis (pez) y voro (alimentarse); por lo tanto el nombre científico de ...
Acutolysin A, which is isolated from the snake venom of Agkistrodon acutus, is a member of the SVMPs subfamily of the metzincin family, and it is a snake venom zinc metalloproteinase possessing only one catalytic domain. The catalytic zinc ion, in the active site, is coordinated in a tetrahedral manner with three imidazole nitrogen atoms of histidine and one oxygen atom. It is uncertain whether this oxygen atom is a water molecule or a hydroxide ion just from the three-dimensional X-ray crystal structure. The identity of the fourth ligand of zinc is theoretically determined for the first time by performing both combined quantum mechanical and molecular mechanical (QM/MM) simulation and high-level quantum mechanical calculations. All of the results obtained indicate that the fourth ligand in the active site of the reported X-ray crystal structure is a water molecule rather than a hydroxide anion. On the basis of these theoretical results, we note that the experimental observed pH dependence of ...

Common Effects of snake Bite. 1. The victims limbs quickly start swelling as the body resists the effects of the cottonmouth snake venom. The swelling is as a result of body fluids collecting around the bite area which gradually spreads to other body parts. The swollen body parts redden followed by severe itching. To avoid discomfort brought on by swelling, immediately loosen the clothes around the swollen areas.. 2.The effects of the bite are similar to the septic shock symptoms. The symptoms include chills, increased heart pulse rate and trembling. The symptoms are due to the natural body response to the snakes venom, or infection that affects the body tissues and the blood. In case the body immune system is weak, the symptoms become very severe in a short time.. 3. Due to the infection and the action of the venom on the bodys muscle tissues, the muscle loses functioning which leads to paralysis of the victim. Fortunately, paralysis resulting from snake bite recede once treatment is ...

Gordon W. Schuett, Ph.D. (born March 5, 1957) is an American evolutionary biologist and herpetologist who has conducted extensive research on reptiles. His work has focused primarily on snakes, but he has also published on turtles, lizards and amphibians. His most significant contributions have been to the studies of hormonal control of reproduction and behavior, winner-loser effects, long-term sperm storage, mate competition, and parthenogenesis. Schuett received a masters degree in biology from Central Michigan University in 1986, under the academic guidance of James C. Gillingham. His 88-page thesis was titled "Selected Topics on Reproduction in the Copperhead, Agkistrodon contortrix (Serpentes, Viperidae)". Schuett then attended The University of Wyoming where he earned his Ph.D. in 1994 under the guidance of David Duvall and James D. Rose. His dissertation, titled "Determinants of Fighting Success in Male Copperheads (Serpentes, Viperidae)," was a major contribution to the field of animal ...
... System of the Copperhead Snake. The reproductive system of the copperhead is very similar in structure and function to the various other classes, with the exception of the hemipenes, which is analogous to the phallus in the Canvasback Duck and the penis in other taxa. The testes are usually adjacent to each other, and the right one is located more anteriorly in snakes. The testes are where the sperm originates; from there it is expelled into the epididymis, and then carried through the vas deferens that run to the cloaca. From the cloaca the sperm enter the hemipenes, which protrude through the cloaca (Zug et al 2001). The cloaca is present in most primitive gnathostomes and persists in embryos of almost all vertebrates. For this reason the cloaca in reptiles as well as birds seems to be a primitive vertebrate feature. External fertilization seems to be most common in early vertebrates, while internal fertilization using an intermittent organ such as the hemepenes in the copperhead ...
Snakes bite between 5,000 to 8,000 people every year in America & are a continuous risk to humans. The first venomous snake worth mentioning is the copperhead, which is a type of pit viper characterized by the hourglass markings along its body & copper-colored triangular head. Theyre found from Massachusetts all the way down to Texas. Another venomous North American snake is the coral snake. You can easily spot them by their red, yellow, & black bands on their bodies. But be wary around them, for one bite will cause your nervous system to shut down & your heart to stop beating. Lastly, we have the cottonmouth, or water moccasin. When it feels annoyed or threatened, the cottonmouth stands its ground & gapes repeatedly at its intruder, thus exposing the light, cotton-colored lining of its mouth.. ...

Springdale Police say they arrested Ryan Cornelison and Aaron Hull in connection with a copperhead snake bite in the garden center at a Springdale Walmart two weeks ago.
This note documents a predation event on a juvenile Blotched Bluetongue Lizard (Tiliqua nigrolutea) by a Highlands Copperhead (Austrelaps ramsayi) in the Blue Mountains, Australia. The diet of elapid snakes in the genus Austrelaps consists mainly of frogs and small skinks. Adults of the larger Tiliqua species may be too large for Austrelaps species to consume, and juveniles of these larger Tiliqua are possibly approaching the larger end of consumable prey items for Austrelaps ...

Well I guess we could form a club ...but something tells me we will have very few members here on FR ...possibly shunned or excommunicated by the rest of the Forum.. Sorry to hear that your neighbors have eradicated the harmless snake population ...I can understand killing a poisonous snake in an area where it is likely to come in contact w/humans or pets ...although, personally, I would choose to relocate it to a remote area if possible. Unfortunately most people cant tell one snake from another; so, naturally, they kill them all our of fear.. I try to let my neighbors know I will gladly be the "go to guy" to remove any snakes from their premises ...usually its too late, though, by the time I find out someone has already killed another "copperhead" ...last one turned out to be a beautiful young eastern kingsnake; how they thought that was a "copperhead" I will never know ...same/same w/northern brown snakes/ring-necked snakes/mole kingsnakes ...all "copperheads" to the locals..

The western cottonmouth is confined to swamps and wetlands in the southeastern part of the state and to the rocky streams and river sloughs in the southern Ozarks (Figure 1). They are active from late April to early October. Females bear eight or nine young in August or September, although the number may range from five to 15. Young cottonmouths are superficially patterned like a copperhead but are not reddish. The tip of the tail is usually yellow. Adults can be 3 to 4 feet long. This heavy-bodied snake is dangerously venomous and, contrary to popular belief, can bite underwater.. ...
White Sea Urchin (Echinus acutus), is a species of sea urchin in the Echinidae family. It is found in the Eastern Atlantic Ocean, the Mediterranean Sea, the North Sea and the English Channel at depths up to 330 feet below sea level. It is found mainly on coarse substrates with mud and gravel.. The White Sea Urchin grows to a diameter of 6 inches. The test (shell) is circular in cross section but rises conically to the apex (tip) of the shell. This species is generally reddish-brown or green with white stripes on the ambulacra (radial or underside). The primary spines on the shell are long and tapering. The secondary spines are shorter. The mouth is surrounded by numerous pedicellariae (pincer-like claws).. This sea urchin is an omnivore and typically feeds on algae and small invertebrates.. ...

A photo of a perfectly camouflaged snake has social media users straining their eyes to spot the seemingly invisible predator among a bed of dead leaves and twigs.
I rolled twice around the entire mountain bike trail, well the part that is on the north/west side of the river. I do not venture across the scary bridge that crosses the Trinity River to reach the trails on that side of the river. Last week a couple of bikers told me that a large section of those trails are like the EKG section of the River Legacy Park trails. EKG is too much for me. That and I got myself lost just walking in the EKG section ...
Agkistrodon piscivorus is a generalist predator that feeds on a variety of prey, including snakes (Gloyd and Conant 1990. Snakes of the Agkistrodon Complex: A Monographic Review. Society for the Study of Amphibians and Reptiles, Oxford, Ohio. 614 pp.; Lillywhite et al. 2002. Herpetol. Rev. 33:259-260; Hill and Beaupre 2008. Copeia 2008:105-114). Cemophora coccinea (Scarletsnake) is not known as one of the 26 species of snakes consumed by A. piscivorus (Ernst and Ernst 2011. Venomous Reptiles of the United States, Canada, and Northern Mexico: Volume 1. Johns Hopkins University Press, Baltimore, Maryland. 193 pp.). On 16 June 2015, at 2210 h, we found a dead-on-road A. piscivorus (total length [TL] = 51.0 cm) in Everglades National Park on Main Park Road, 1.88 km S Pa-hay-okee, Miami-Dade Co., Florida, USA (25.414085°N, 80.78183146°W, WGS84; elev. 3 m).

Most people up here claim theyve got Irish or Scottish, or some kind of blood in them, and I think thats probably true. Especially if you listen to the folks who drive up here from the universities to tell us about the culture they says disappearing. They will go and knock on cabin doors looking to get Jack Tales on their tape recorders, snoop through barns, flag elderly men down from tractors to ask them to sing a couple of old-time reels.". His 25 years have left Barfield a bit cynical about the regions cultural heritage and romanticized tales concerning local history. However, experience has taught the sheriff one singular truth: "People out in these parts take hold of religion like it is a drug, and they dont want to give it up when theyve got hold it. It feeds them, and when they are on it they are likely to do anything these little backwoods churches tell them to do.". Of course, if you are a student of Appalachian literature, you know what is coming next: rattlesnakes, copperheads, ...

PALM HARBOR, Fla. â€" Adam Hadwin knows all about going low on the PGA Tour. Still to be determined is whether that translates into a victory.. The Canadian, who shot a 59 at the CareerBuilder Challenge two months ago, ran off five straight birdies to start the back nine Friday at the Valspar Championship and posted a 7-under 64 to take a one-shot lead into the weekend.. Even playing in the afternoon in a strong breeze and crustier putting surfaces, Hadwin one-putted every hole on the back nine until he had no choice but to lag a 20-foot birdie attempt on the 18th hole to make sure it didnt race all the way off the green and into the fairway.. He shot 29 on the back and reached the halfway point at Innisbrook at 10-under 132, one shot clear of Jim Herman.. "You cant go out and shoot 7 under on the Copperhead Course without doing everything right," said the native of Abbotsford, B.C. "I put myself in position off the tee box, hit a ton of fairways then just really hit the irons solidly ...
At this point, we hiked up the little side trail that follows a small stream, referred to as Copperhead Creek, up the hill to see some interesting features in the rock outcrops above the stream. Retired UGA geology professor, Dr. Gilles Allard, has described the geology of the Purple and Orange Trails and this description is included as an appendix to the Botanical Gardens pamphlet "The Plant Communities Along the Purple/Orange Trail at the State Botanical Garden of Georgia". The subject rock outcrops are seen high above the small stream approximately 150 feet from the Sitting Bench. Visible in this outcrop of migmatitic gneiss are small, tight folds in the rock. This can be seen in relatively fresh, broken surfaces, where the alternating layers of dark and light colored minerals reveal a wavy pattern of small, tight folds. It can also be seen in parts of the outcrop that are covered in moss. The minerals comprising the darker layers, seen in the fresher rock, are more susceptible to chemical ...

Non-venomous, Nerodia fasciata hunts fish and a wide variety of amphibians, particularly frogs. A nocturnal hunter, N. fasciata spends the day resting in the vegetation along the waters edge or hides deep in rodent burrows along the bank. Many species of Nerodia are suspected of being venomous cottonmouths (Agisktrodon piscivorus) but the behavior of the two snakes is tremendously different. Cottonmouths move much more slowly in the water, often keeping their entire body afloat. When threatened, cottonmouths show off their namesake white lined mouth in a defensive posture. All species of Nerodia are quick, agile swimmers which move rapidly through the water and water snakes never gape open their mouths if threatened. They may instead flatten their bodies in an attempt to look larger.. ...

Is that gecko or GEICO? Then there is other wildlife. My sister had a garter snake in her garden once. I dont have any snakes though. Snakes arent bad as long as they are not copperheads which we have plenty of. One of the barns where I kept my thoroughbred, Merlin, had black snakes in it about the same diameter around as beer cans. Kind of creepy but a necessity since they eat copperhead eggs. They also eat mice, and had to be put up with because we had a big time mice problem and the barn manager didnt like cats and didnt want to have any around. Ill take warm blooded and furry rodent control specialists over scaly and slithery ones any day. Lots of fun when I had my horse in cross ties and one of those snakes drops down from the rafters right in front of him, or Id go into the feed room to fix breakfast for everyone and find a pair of beady eyes just staring at me. Then we had these baby snakes infesting the office once. Bit one of the secretaries. We once had woodchucks living under ...
A Chinese student who for 22 years happily carried the name Zhao C (Zhao "Left Crescent") fell foul of the powers that be when he came to get a new "second generation" ID card at his local Public Security Bureau (PSB) - police informed him "it was technically not possible to put English letters in names and told him to get a new name".. Zhao, of Jiangxi Province, was named C in honour of China - a patriotic move also designed "to encourage the boy to learn English", as Xinhua puts it. He told the news agency: "I was registered at birth under that name. I like my name. It is easy to remember and my classmates called me Cici.". Cs lawyer dad, Zhao Zhirong, last year presented his sons case in the Peoples Court of Yuehu District. The court "sided with Zhao and ordered the security bureau to issue a new ID card", although the PSB refused and appealed the ruling.. The matter was finally settled late last month, Danwei reports. During a final hearing, Zhao Zhirong argued that addresses "often ...

The city was home to a largely Spanish-speaking population in the first census, taken in 1850 when California became a state. After statehood, non-Hispanic settlers came to Southern California in increasing numbers. The decade of the 1880s is known as the "Southern California Land Boom" because so many people moved to the state.. In 1853, pro-Southern Copperheads proposed dividing the state of California to create a new Territory of Colorado (at this time the territory that would become the state of Colorado was named "Jefferson"). San Diego Judge Oliver S. Witherby suggested placing the capitol of the new territory in Rancho Rincon del Diablo. He envisioned a railroad connecting San Diego to Fort Yuma through an area about two miles (3 km) south of the current Escondido site, heading east through San Pasqual. With a series of deeds in 1855 and 1856, the rancho was transferred from the heirs of Juan Bautista Alvarado to Witherby.[11] He planned to profit from the town that he believed would be ...

Despite the differences in zoology and toxicology between T albolabris and A halys, AHA has been shown to be more effective than GPVA on a volume basis in the reduction of mouse mortality arising from T albolabris envenoming. In an in-vivo study, the intraperitoneal lethal dose 50 (LD50) of T albolabris (called Cryptelytrops albolabris in the study but T albolabris is the latest name for the same species) was elevated from 0.14 µL to 0.36 µL and 0.52 µL by GPVA and AHA, respectively; and the effective dose 50 was 32.02 µL for GPVA and 6.98 µL for AHA.8 Nonetheless these favourable results for AHA may not be applicable to humans for several reasons. Firstly, haemotoxicity rather than death is the primary concern in T albolabris bite. In the above paper, the authors also pointed out the need for further study of clinically relevant toxicities other than mortality.8 Second, studies in animals revealed that the mortality and haemotoxicity outcomes might not correlate with each other. Of the six ...
Monday at dusk as I approached my lodging a two-ft-long Variable Coral Snake, MICRURUS DIASTEMA, lay upon the steps right before my door. Now that I saw how the snake behaved I grew convinced that another snake Id recently encountered at dusk, also on some steps nearby, also had been a coral. It had been too dark then for me to see the colors, but I clearly saw the shape, the banding and the behavior. The behavior these two snakes shared was this: When the snake grew agitated he squirmed much more vigorously than normal for an escaping snake on a smooth surface, and every couple of seconds the snakes would suddenly launch their heads upwards and snap the air two or three times before falling back onto the ground and continuing to squirm. Up north when I find rattlers, cottonmouths and copperheads in places where they might hurt people I put them into buckets and carry them to more isolated places. These snakes behaved far too violently and aggressively for me to fool with them, and they ...
Metalloproteinases (MPs) are Zn+-dependent endoproteolytic enzymes, abundant in crotalid and viperid snake venoms. Most snake venom metalloproteinases (svMPs) are active on extracellular matrix components and this effect is thought to result in bleeding as a consequence of the basement membrane disruption in capillaries. Jararhagin and ACLH are hemorrhagic svMPs from Bothrops jararaca and Agkistrodon contortrix laticinctus venom, respectively. Both enzymes demonstrate proteolytic activity on fibrinogen and fibronectin and jararhagin inhibits collagen-induced platelet aggregation in vitro. This work describes the expression, purification and successful refolding of the recombinant ACLH zymogen (rPRO-ACLH) as well as the catalytic domain of jararhagin (rCDJARA). the heterologous proteins were produced in E. coli, an in vivo expression system that does not make post-translational modifications. the recombinant refolded proteins did not show any hemorrhagic activity in mice skin, as well as the ...

Subcutaneous injection into mice induces a mild edema. Intravenous and intramuscular injection reduce plasma fibrinogen concentration and increase the levels of fibrin(ogen) degradation products. Intramuscular injection also promotes an increase in the expression of proMMP-9, but is unable to activate it.

Lentell, et al., Anatomy, three-dimensional reconstructions, and volume estimation of the brain of the Atlantic White-sided Dolphin (Lagenorhynchus acutus) from magnetic resonance images, New England Stranding Conference, 2004. Thyroid hormones (TH) play an integral role in neuro-development, particularly in the maturation of the corpus callosum, cerebellum, hippocampus, and inner ear. In rodents, it has been shown that persistent organic pollutants (POPs), particularly polychlorinated biphenyls (PCBs), interfere with TH signaling. These pollutants are widespread in the marine environment and biomagnify in marine mammals to very high levels. Brominated flame-retardants have also recently been shown to interfere with the TH system in experimental animals.. ...
