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)

TY - JOUR. T1 - Functional and sequence characterization of agkicetin, a new glycoprotein IB antagonist isolated from agkistrodon acutus venom. AU - Chen, Yuh Ling. AU - Tsai, Inn Ho. PY - 1995/5/16. Y1 - 1995/5/16. N2 - A new glycoprotein Ib (GPIb) antagonist, agkicetin, was purified from the venom of Agkistrodon acutus and characterized. It is a disulfide-linked heterodimer consisting subunits of 15 and 14 kDa. The subunits are homologous to each other and to other snake venom proteins of the C-type (Ca2+-dependent) lectin superfamily. Agkicetin behaved as a potent antagonist of von Willebrand Factor (vWF)-induced platelet agglutination (IC50=12.5 nM) and bound specifically to GPIb of fixed platelets with high affinity (Kd=38 nM). It did not bind coagulation factor IX and thrombin. Monoclonal antibody against epitope on the N-terminal domain of GPIb competed the binding of agkicetin with platelets. Reduced and alkylated agkicetin lost most of its inhibitory efficacy toward vWF-induced platelet ...

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 ...
The snake venom gland is a specialized organ, which synthesizes and secretes the complex and abundant toxin proteins. Though gene expression in the snake venom gland has been extensively studied, the focus has been on the components of the venom. As far as the molecular mechanism of toxin secretion and metabolism is concerned, we still knew a little. Therefore, a fundamental question being arisen is what genes are expressed in the snake venom glands besides many toxin components? To examine extensively the transcripts expressed in the venom gland of Deinagkistrodon acutus and unveil the potential of its products on cellular structure and functional aspects, we generated 8696 expressed sequence tags (ESTs) from a non-normalized cDNA library. All ESTs were clustered into 3416 clusters, of which 40.16% of total ESTs belong to recognized toxin-coding sequences; 39.85% are similar to cellular transcripts; and 20.00% have no significant similarity to any known sequences. By analyzing cellular functional
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, ...

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 ...
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 ...

The only thing more boring than listening to someone recount their dreams is listening to them drone on about how unspeakably busy they are, so suffice it to say I was already a very busy person, and then I had a baby. That was three years ago, and now, as I write this, I have had TWO babies, written two books, and moved to a fixer house that needed things like heat and wiring and fewer blackberry vines in the attic. Plus, I started the flash fiction podcast Toasted Cake (now at 94 episodes!) and continued to work as a face painter. Among other things.. The biggest change is that Ive had to learn how to write on command. No more sitting around waiting for the muse, warming up (usefully) by writing something else entirely or (un-usefully) by playing five games of freecell. Heres some take-away for you:. ...
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 ...

Adults grow to a typical length (including tail) of 50-95 cm (20-37 in). Some may exceed 1 m (3.3 ft), although that is exceptional for this species.[8] Males are usually larger than females. Good-sized adult males usually do not exceed 74 to 76 cm (29 to 30 in), and females typically do not exceed 60 to 66 cm (24 to 26 in).[9][10] In one study, males were found to weigh from 101.5 to 343 g (3.58 to 12.10 oz), with a mean of roughly 197.4 g (6.96 oz).[11] According to a different study, females have a mean body mass of 119.8 g (4.23 oz).[12] The maximum length reported for this species is 134.6 cm (53.0 in) for A. c. mokasen (Ditmars, 1931). Brimley (1944) mentions a specimen of A. c. mokasen from Chapel Hill, North Carolina, that was four feet, six inches (137.2 cm), but this may have been an approximation. The maximum length for A. c. contortrix is 132.1 cm (52.0 in) (Conant, 1958).[5] The body is relatively stout and the head is broad and distinct from the neck. Because the snout slopes ...

Reproductive 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.. ...

Definition: Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke. When they push water directly backwards, this moves their body forward, but as they return their limbs to the starting position, they push water forward, which will thus pull them back to some degree, and so opposes the direction that the body is heading. This opposing force is called drag. The return-stroke drag causes drag swimmers to employ different strategies than lift swimmers. Reducing drag on the return stroke is essential for optimizing efficiency ...

N2 - Exposure of plasma to iron and carbon monoxide (CO) renders fibrinogen resistant to fibrinogenolytic or thrombin-like activity contained in pit viper venom. However, the direct effects of iron/CO on venom activity are unknown. Thus, we assessed if four different, metalloproteinase containing snake venoms exposed to iron/CO or CO alone could attenuate their fibrinogenolytic or thrombin-like activity. Venom (0-500 μg ml-1) was exposed to 0-10 μM FeCl3 and/or 0-100 μM carbon monoxide releasing molecule-2 (CORM-2), or inactivated CORM-2 (iCORM-2) for 3 min at room temperature.

Northern cottonmouth (venomous). Photo credit: John White. By J.D. Kleopfer, Herpetologist, Virginia Department of Game and Inland Fisheries. Spring is here and the fishing is heating up. Its also that time of the year when lots of other critters are heating up and becoming active. Among these critters are watersnakes and cottonmouths (aka water moccasins). Here are some helpful tips on identification and behavior of these often misunderstood animals.. The distribution of cottonmouths in Virginia is primarily limited to the southeastern part of the state, particularly the southern regions of Virginia Beach and Chesapeake with isolated populations in Brunswick, Chesterfield, Dinwiddie, Greensville, Prince George, Southampton, Surry, Sussex, and York counties, and the cities of Suffolk and Newport News. On the other hand, watersnakes are found statewide in every county and municipality. They also occupy a wider variety of aquatic habitats including lakes and reservoirs, streams, rivers, ditches ...

PALM HARBOR, Fla. †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..

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 ...
Nature has never been my thing. Im more in tune with books and technology - a Kindle freak and a camera junkie. Our kids had the usual assortment of pets - from dogs and cats to rabbits and hamsters. Our family frequented zoos, of course, and even took a photographic safari to Mala Mala in Africa, but actually seeking out animals in the wild on my own was absolutely foreign to me. The closest I ever came to nature was when a wood duck plummeted down our fireplace chimney in Minnesota and had to be rescued.. Eventually we moved to Texas and I was forced to confront nature in the raw. When a wolf spider the size of my fist decided to explore my VW convertible, I exploded from the car screaming, Ragno, Ragno -Aiuto! Aiuto!

The Wrongful Case of Zhao Zuohai. In early May, Chinese official media reported on the acquittal of 57-year old Zhao Zuohai, who served more than 10 years in prison on a wrongful murder conviction, before the victim reappeared on April 30, 2010. According to a May 11 Beijing News article (via Peoples Daily) and a May 14 China Daily article, public security officials began to suspect Zhao Zuohai for the murder of missing neighbor Zhao Zhenshang in 1998, since the two had been involved in a physical altercation in 1997. A May 9 Xinhua article reported that authorities arrested Zhao Zuohai in 1999, after a headless body was discovered in the village. Despite the fact that authorities lacked DNA proof that the body belonged to Zhao Zhenshang, Zhao reportedly confessed to the murder nine times between 1999 and 2001, according to the May 14 China Daily article and a May 11 Procuratorial Daily article. On December 5, 2002, the Shangqiu City Intermediate Peoples Court sentenced Zhao to death with a ...
