The most common live in tropical or subtropical areas. They are nocturnal and feed principally on insects and other arthropods. They are large arachnids but do not attack man spontaneously. They have a venomous sting. Their medical significance varies considerably and is dependent on their habits and venom potency rather than on their size. At most, the sting is equivalent to that of a hornet but certain species possess a highly toxic venom potentially fatal to humans.

Centipede (Scolopendra gigantea Linneaus 1758) envenomation in a newborn. (1/67)

The first case of centipede (Scolopendra gigantea Linneaus 1758) envenomation in a newborn is reported. When first examined, approximately 6 hours after the bite, the 28-day-old girl was irritable, with uncontrollable cry and intense local pain, oedema, local hyperthermia, and blood clots at punctures. Uncontrollable crying in neonates should rise the possibility of an insect or arachnid sting.  (+info)

Dufour glands in the hymenopterans (Apidae, Formicidae, Vespidae): a review. (2/67)

Associated to the sting apparatus of the aculeate hymenopterans is found the poison gland, originated from the glands associated to the ovipositor of the non-aculeate hymenopterans and the less derived Dufour gland, homologue of the coletterial gland of other insects, and found in all hymenopteran females. The Dufour gland functions is mostly uncertain in hymenopterans but in ants it is involved with communication and defense and in non social bees with the nest building and protection. In wasps possibly with kin-recognition. Differences in morphology and chemical composition of the gland secretion were observed among species, in the same species, between the castes in the social species and among individual of the same caste playing different tasks or belonging to different nest. Its original function of egg-protective substance producing, or favoring the oviposition, appear to have been replaced or complemented in hymenopterans by the production of semiochemicals with function in communication.  (+info)

Antithrombotic effect of Lonomia obliqua caterpillar bristle extract on experimental venous thrombosis. (3/67)

The venom of Lonomia obliqua caterpillar may induce a hemorrhagic syndrome in humans, and blood incoagulability by afibrinogenemia when intravenously injected in laboratory animals. The possible antithrombotic and thrombolytic activities of L. obliqua caterpillar bristle extract (LOCBE) were evaluated in this study. The minimal intravenous dose of the extract necessary to induce afibrinogenemia and anticoagulation was 3.0 and 10.0 microg protein/kg body weight for rabbits and rats, respectively. In rabbits, this dose induced total blood incoagulability for at least 10 h and did not reduce the weight of preformed venous thrombi, in contrast to streptokinase (30,000 IU/kg). In rats, pretreatment with 5.0 and 10.0 microg/kg LOCBE prevented the formation of thrombi induced by venous stasis or by injury to the venous endothelium. The dose of 5.0 microg/kg LOCBE did not modify blood coagulation assay parameters but increased bleeding time and decreased plasma factor XIII concentration. When the extract was administered to rats at the dose of 10.0 microg/kg, the blood was totally incoagulable for 6 h. These data show that LOCBE was effective in preventing experimental venous thrombosis in rats, justifying further studies using purified fractions of the extract to clarify the mechanisms of this effect.  (+info)

A role for Ca2+ stores in kainate receptor-dependent synaptic facilitation and LTP at mossy fiber synapses in the hippocampus. (4/67)

Compared with NMDA receptor-dependent LTP, much less is known about the mechanism of induction of NMDA receptor-independent LTP; the most extensively studied form of which is mossy fiber LTP in the hippocampus. In the present study we show that Ca2+-induced Ca2+ release from intracellular stores is involved in the induction of mossy fiber LTP. This release also contributes to the kainate receptor-dependent component of the pronounced synaptic facilitation that occurs during high-frequency stimulation. We also present evidence that the trigger for this Ca2+ release is Ca2+ permeation through kainate receptors. However, these novel synaptic mechanisms can be bypassed when the Ca2+ concentration is raised (from 2 to 4 mM), via a compensatory involvement of L-type Ca2+ channels. These findings suggest that presynaptic kainate receptors at mossy fiber synapses can initiate a cascade involving Ca2+ release from intracellular stores that is important in both short-term and long-term plasticity.  (+info)

Efficacy and safety of rush immunotherapy in patients with Hymenoptera allergy in Japan. (5/67)

In Japan, approximately 40 persons die annually from anaphylaxis caused by Hymenoptera stings. Venom immunotherapy is considered safe and effective for the treatment of allergic systemic reactions caused by Hymenoptera stings in patients with Hymenoptera allergy. We studied the efficacy and safety of rush immunotherapy in patients who had a history of systemic reactions to Hymenoptera stings in Japan. Between 1988 and 2002, 95 patients with a history of systemic reactions to Hymenoptera stings were investigated. The stings originated from honeybees in 5 patients, yellow jackets in 28, wasps in 48, both yellow jackets and wasps in 9, and both yellow jackets and honeybees in 5. All patients had venom-specific IgE antibodies in sera (RAST score > or = 2) and received rush immunotherapy with venom extracts at our hospital. Forty-three patients had 63 field re-stings during immunotherapy. Of these patients, 41 (95.3%) with 59 field re-stings (93.7%) had no systemic reactions. Two patients (4.7%) with four field restings (6.3%) had anaphylactic shock. Although anaphylactic reactions developed in two patients (2.1%) during rush immunotherapy with honeybee venom and one patient (1.1%) during maintenance therapy wasp venom, systemic adverse reactions were mitigated by treatment with antihistamines before venom injection. Our results show that immunotherapy is safe and effective for the prevention of systemic reactions to Hymenoptera re-stings in patients with Hymenoptera allergy. We therefore recommend that patients who are allergic to Hymenoptera venom prophylactically receive immunotherapy.  (+info)

Importance of the inducible costimulator molecule for the induction of allergic immune responses and its decreased expression on T helper cells after venom immunotherapy. (6/67)

The inducible costimulator (ICOS), a newly identified member of the CD28 receptor family that is induced after T-cell activation, and its ligand (ICOSL), being expressed on activated monocytes and dendritic cells play a key role in T-cell-mediated immune responses. As ICOS costimulation also seems to regulate T helper 2 effector cells, the aim of this study was to analyse the function of this molecule in allergic immune responses and their specific therapy, mainly venom immunotherapy (VIT). CD4+ T cells from grass pollen-, or bee or wasp venom-allergic donors were stimulated in the presence of autologous mature dendritic cells, which were pulsed with different allergen doses. In this system, costimulation of ICOS strongly enhanced the production of the T helper 2 cytokines interleukin (IL)-4, IL-5 and IL-10 and, to a lesser extent, secretion of the T helper 1 cytokine, interferon-gamma. Expression of ICOS on CD4+ T cells was induced, in a dose-dependent manner, after a few days of stimulation with allergen-pulsed dendritic cells, reaching a peak on day 6. The upregulation of ICOS after stimulation with venom allergens was significantly reduced after VIT. Addition of exogenous IL-10 (which is induced during VIT) to the co-cultures before VIT also led to an inhibition of ICOS expression, while blocking of IL-10 in co-cultures after VIT partially restored the expression of ICOS. These data indicate that the inhibition of T cells after immunotherapy also involves decreased induction of the costimulatory molecule ICOS, which, in turn, seems to be dependent on the presence of IL-10, also associated with the inhibited status of T cells after VIT. This makes the ICOS-ICOSL pathway a potential target for therapeutic intervention in T helper 2-mediated diseases, such as allergic diseases.  (+info)

The evolving global epidemiology, syndromic classification, management, and prevention of caterpillar envenoming. (7/67)

Caterpillars are the wormlike, larval forms of butterflies and moths of the insect order Lepidoptera. Next to flies, lepidopterans are the most abundant arthropods with more than 165,000 species worldwide, and with most species posing no human threats. However, caterpillar species from approximately 12 families of moths or butterflies worldwide can inflict serious human injuries ranging from urticarial dermatitis and atopic asthma to osteochondritis, consumption coagulopathy, renal failure, and intracerebral hemorrhage. Unlike bees and wasps, envenoming or stinging caterpillars do not possess stingers or modified ovipositors attached to venom glands, but instead bear highly specialized external nettling or urticating hairs and breakaway spines or setae to defend against attacks by predators and enemies. Since the 1970s, there have been increasing reports of mass dermatolgic, pulmonary, and systemic reactions following caterpillar encounters throughout the world.  (+info)

A catalog for the transcripts from the venomous structures of the caterpillar Lonomia obliqua: identification of the proteins potentially involved in the coagulation disorder and hemorrhagic syndrome. (8/67)

Accidents with the caterpillar Lonomia obliqua are often associated with a coagulation disorder and hemorrhagic syndrome in humans. In the present study, we have constructed cDNA libraries from two venomous structures of the caterpillar, namely the tegument and the bristle. High-throughput sequencing and bioinformatics analyses were performed in parallel. Over one thousand cDNAs were obtained and clustered to produce a database of 538 contigs and singletons (clusters) for the tegument library and 368 for the bristle library. We have thus identified dozens of full-length cDNAs coding for proteins with sequence homology to snake venom prothrombin activator, trypsin-like enzymes, blood coagulation factors and prophenoloxidase cascade activators. We also report cDNA coding for cysteine proteases, Group III phospholipase A2, C-type lectins, lipocalins, in addition to protease inhibitors including serpins, Kazal-type inhibitors, cystatins and trypsin inhibitor-like molecules. Antibacterial proteins and housekeeping genes are also described. A significant number of sequences were devoid of database matches, suggesting that their biologic function remains to be defined. We also report the N-terminus of the most abundant proteins present in the bristle, tegument, hemolymph, and "cryosecretion". Thus, we have created a catalog that contains the predicted molecular weight, isoelectric point, accession number, and putative function for each selected molecule from the venomous structures of L. obliqua. The role of these molecules in the coagulation disorder and hemorrhagic syndrome caused by envenomation with this caterpillar is discussed. All sequence information and the , including figures and tables with hyperlinks to FASTA-formatted files for each contig and the best match to the databases, are available at http://www.ncbi.nih.gov/projects/omes.  (+info)

Lonomia obliqua (or giant silkworm moth, a name also used for a wide range of other Saturniid moths) is a species of Saturniid moths from South America. It is famous for its larval form, rather than the adult moth, primarily because of the caterpillars defense mechanism, urticating bristles that inject a potentially deadly venom. The caterpillar has been responsible for many human deaths, especially in southern Brazil. Its venom has been the subject of numerous medical studies. These caterpillars are about 4.5 to 5.5 centimetres (about 2 in) long, with background colors ranging from green to brown. Well camouflaged, they have rows of tubercles crowned with whorls of easily detachable spines of different sizes. Caterpillars of many species can cause irritation by hollow body hairs that envenom or detach easily, or can be poisonous if ingested; however, prior to investigations into Lonomia caterpillars, it was not known that caterpillars could produce toxins which in sufficient quantities could ...
Venomous animals have evolved with sophisticated bio-chemical strategies to arrest prey and defend themselves from natural predators. In recent years, peptide toxins from venomous animals have drawn considerable attention from researchers due to their surprising chemical, biochemical, and pharmacological diversity. Similar to other venomous animals, centipedes are one of the crucial venomous arthropods that have been used in traditional medicine for hundreds of years in China. Despite signifying pharmacological importance, very little is known about the active components of centipede venoms. More than 500 peptide sequences have been reported in centipede venomous glands by transcriptome analysis, but only a small number of peptide toxins from centipede has been functionally described. Like other venomous animals such as snakes, scorpions, and spiders, the venom of centipedes could be an excellent source of peptides for developing drugs for treatments as well as bio-insecticides for agrochemical

The best way to avoid getting bitten by black widow spiders is to be careful in areas where they like to spend time. Do not play around in rock piles or wood piles. If you are working outside in the yard in big piles of logs or leaves, wear gloves. Be sure to shake out blankets and clothing that have been stored in the attic or the basement, or if they have been in a closet but not used for a long time.

Treatment failure during venom immunotherapy (VIT) may be associated with a variety of risk factors. Our aim was to evaluate the association of baseline serum tryptase concentration (BTC) and of other parameters with the frequency of VIT failure during the maintenance phase. In this observational prospective multicenter study, we followed 357 patients with established honey bee or vespid venom allergy after the maintenance dose of VIT had been reached. In all patients, VIT effectiveness was either verified by sting challenge (n = 154) or patient self-reporting of the outcome of a field sting (n = 203). Data were collected on BTC, age, gender, preventive use of anti-allergic drugs (oral antihistamines and/or corticosteroids) right after a field sting, venom dose, antihypertensive medication, type of venom, side effects during VIT, severity of index sting reaction preceding VIT, and duration of VIT. Relative rates were calculated with generalized additive models. 22 patients (6.2%) developed ...

Fatty liver hemorrhagic syndrome (also referred to as fatty liver syndrome), a disease in chickens and other birds, affects only hens (females). Birds with this disease have large amounts of fat deposited in their liver and abdomen. This often results in an enlarged liver that is easily damaged and prone to bleeding. In some cases the disease is fatal, usually as a result of blood loss from an internal hemorrhage in the liver. The hemorrhage often occurs when a hen is straining to lay her egg. Fatty liver hemorrhagic syndrome is "the major cause of mortality in laying hens." Excessive dietary energy intake is believed to be the cause of fatty liver hemorrhagic syndrome. Heredity may also play a role, but it is not the entire cause for the disease. Birds housed in cages will more likely be affected because they are unable to exercise to burn off the extra dietary energy. Walking hens are less likely to develop this problem. The disease is observed most often in birds that appear to be healthy and ...

Spoiler Alert! Avengers- Age of Ultron. The overwhelming outrage Marvel studios felt after the release of Avengers- Age of Ultron from feminists across North America largely focused on the demeaning nature that Black Widow was portrayed as representative of the sexist problems riddling Marvels comics and movies. Yet, while as a character Black Widow was perhaps written into the script using cheap, obvious jokes, is no one going to talk about the revelation that she was forcibly sterilized? Furthermore, that she believes she is a monster because of it?. As a Marvel fan I was shocked at the scene between Natasha Romanoff (Black Widow) and Bruce Banner (The Hulk) where they are playing with the idea of running off together and Banner flips and reveals that he cannot have children and thus there is no future with him. Romanoff then reveals that as a part of the graduation ceremony in…. ...

The eggs of black widow spider (L. tredecimguttatus) have been demonstrated to be rich in toxic proteinaceous components. The study on such active components is of theoretical and practical importance. In the present work, using a combination of multiple biochemical and biological strategies, we isolated and characterized the proteinaceous components from the aqueous extract of the black widow spider eggs. After gel filtration of the egg extract, the resulting main protein and peptide peaks were further fractionated by ion exchange chromatography and reversed-phase high performance liquid chromatography. Two proteinaceous components, named latroeggtoxin-III and latroeggtoxin-IV, respectively, were purified to homogeneity. Latroeggtoxin-III was demonstrated to have a molecular weight of about 36 kDa. Activity analysis indicated that latroeggtoxin-III exhibited neurotoxicity against cockroaches but had no obvious effect on mice, suggesting that it is an insect-specific toxin. Latroeggtoxin-IV, with a

Written by DEVIN GRAYSON & GREG RUCKA Penciled by J.G. JONES & SCOTT HAMPTON Cover by J.G. JONES Natasha Romanov has always led an exciting life - first as a Cold War-era Soviet spy, followed by her defection to the West. She has earned a reputation through the years as a consummate professional, coldly efficient and as deadly as her namesake. Now, her time as Black Widow may be at an end. Yelena Belova, the new Black Widow, seeks to claim the mantle she feels was stolen from her Motherland. Trained in the arts of espionage and combat, and anxious to prove herself and eliminate her counterpart, Belova will stop at nothing to achieve her goal. The battle of the two Widows rages from the deserts of the Middle East to New Yorks Upper West Side. When the smoke clears, will either be left standing?

I kind of admire the attitude Six took with his approach to a followup, and... I find myself actually excited about the upcoming third film." - BC, Human Centipede 2 review. With that, on the behalf of anyone else who gave these movies a pass Id like to apologize for the existence of The Human Centipede 3 [Final Sequence]. Apparently, people like me didnt learn our lesson last time, and now Tom Six has taken it upon himself to push our endurance even further, with a film so ugly that racial slurs barely even register. The "point" of this movie (and possibly the series as a whole) is pretty easy to discern, when Dieter Lasers character (a sadistic prison warden - hes not playing his HC1 character), dressed in attire much like that of Tom Six himself, comes across a prisoner who WANTS to be part of a human centipede. Laser instantly shoots him dead while screaming "I dont want anyone liking this!", and then it finally hit me: we were never supposed to enjoy even the first film of this series. ...

An extract of the venom glands of black widow spiders (BWGE) induces the release of acetylcholine (ACh) from the superior cervical ganglia of rats. The release of ACh follows first-order kinetics, which suggests that the venom either lowers the ganglionic store of ACh, or continually reduces the rate of release. Since ganglionic ACh did not decrease in the presence of BWGE, it is likely that the venom continually reduces the rate of release. The rate constant for BWGE-induced release of ACh is depressed about 45% by treatment of the ganglion with either botulinum toxin or a low Ca++/high Mg++Ringers solution. The rate constant is depressed about 30% by treatment of the ganglion with 8.3 microng/ml of cytochalasin-B. Since these agents inhibit the release of ACh which is elicited by electrical stimulation of the ganglion, it is suggested that one action of BWGE is the stimulation of some step in the physiological mechanism involved in the release of neurotransmitters. Treatment of the ganglion ...
Like a Black Widow spider, infotainment sensation Megyn Kelly has advanced both her personal and career life sniffing out testosterone and then feeding off male prey. Prior to her meteoric rise to fame, Megyn was married to an anesthesiologist named David Kendall. Mr. Kendall said that on the day the couple married, the priest counseled Megyn on the importance of taking care of her husband. Megyn responded to the advice by asking, What about him taking care of his wife? The ambitious celebrity enhanced her résumé, transforming from a rookie news anchor into a self-impressed show boater with the same self-regard. Unlike the deadly arachnoid, Megyn doesnt need to physically mate with her prey to get what she needs before the poison flows, but she openly exploits her female sexuality.

Legally blind in his left eye, pitcher Jeff Seale was nonetheless selected by the New York Mets in the second round of the 1988 amateur draft.

The mental block that the Centipedes Dilemma creates is usually temporary. If a task or action can be taught, then it can be understood, and thus a process one has previously performed intuitively can be learned consciously, removing the mental block ...

A new generation of environmentally safe insecticides that only target disease-carrying insects or those that damage crops is emerging from surprising research into the venom of one of the worlds deadliest creatures - the Australian Blue Mountains funnel-web spider.. The spiders potentially fatal effect on humans is an unlucky side-effect of just one of the 200 or so compounds its venom contains. But Dr Glenn King, professor of Biochemistry and Microbiology at the University of Connecticut Health Centre in the U.S. has said that many of the other compounds kill particular insects and are otherwise harmless.. This means the spiders venom has great potential to be developed as insecticides and could be used in two ways; as conventional sprayed pesticides, or delivered by insect-specific viruses that have been genetically engineered to contain a spider-venom gene.. "The latter approach is actually better from an environmental point of view because it is like a magic bullet that targets a ...
Dont worry if you notice occasional centipedes and millipedes in your home. In fact, centipedes may help control populations of other pests, such as flies and cockroaches. If you have a lot of centipedes or millipedes, however, decrease the humidity inside the home and remove moist, decaying matter from outside the home. Sealing cracks in the foundation and using screens in doors and windows may also help keep centipedes and millipedes out of your home. Use chemical pesticides as a last resort.. ...
Centipedes have a painful bite, but the good news is that the pain is often the worst of it. Centipede bites are not toxic enough to be deadly. If you are bitten by a centipede, here are steps that you can take to treat the bite.

When individual stars form from molecular clouds of gas and dust they produce intense radiation and very strong particle winds. Both the radiation and the stellar winds blow the dust outward from the star creating a cavity or, bubble. In the case of the Black Widow Nebula, astronomers suspect that a large cloud of gas and dust condensed to create multiple clusters of massive star formation. The combined winds from these large stars probably blew out bubbles into the direction of least resistance, forming a double-bubble ...

TY - JOUR. T1 - BLT2 is upregulated in allergen-stimulated mast cells and mediates the synthesis of Th2 cytokines. AU - Cho, Kyung Jin. AU - Seo, Ji Min. AU - Lee, Min-Goo. AU - Kim, Jae-Hong. PY - 2010/11/15. Y1 - 2010/11/15. N2 - Mast cells are effector cells that mediate the allergic response through Ag stimulation of IgE bound to FcεRI. In allergic reactions, cross-linking of the surface receptors for IgE on mast cells results in the synthesis of Th2 cytokines such as IL-4 and IL-13, which are critical for the initiation and progression of the allergic response. Despite the important roles of these cytokines, the signaling mechanism by which Ag stimulation mediates the production of IL-4 and IL-13 in mast cells is not clearly understood. In the present study, we found that Ag-stimulated bone marrow-derived mast cells (BMMCs) highly upregulated the expression of BLT2, a leukotriene B 4 receptor, and that blockade of BLT2 with the specific antagonist LY255283 or small interfering RNA ...
1. The oogenesis of Scolopendra has been worked out with vital dyes and the routine laboratory technique.. 2. The Golgi elements exist in the form of vacuoles with watery and non-fatty contents.. 3. The solid Golgi elements are artefacts due to the excessive precipitation of metallic osmium inside the vacuoles.. 4. The Golgi crescents are either artefacts due to incomplete blackening of a vacuole, or they are simply the optical sections of an osmicated vacuole.. 5. The Golgi vacuoles give rise to fatty yolk-vacuoles by a process of growth and deposition inside them of free fat not miscible with the general cytoplasm.. 6.

Serum IgG and IgG subclass antibody testing have been proposed as methods of identifying levels of sensitivity to various allergens, but there is disagreement in the medical community about how effective IgG antibody testing is for this purpose.. After evaluating the clinical literature, Harvard Pilgrim has found that while there is evidence to support the medical necessity of IgG testing for venom immunotherapy, there is not sufficient clinical evidence to support its use for other conditions, such as food allergy. As a result, effective July 1, 2014, Harvard Pilgrim will cover IgG and IgG subclass allergen testing for venom immunotherapy only. For more information, please refer to the Serum IgG Allergy Testing Medical Policy.. ...

The Infraorder Mygalomorphae is one of the three main lineages of spiders comprising over 3,000 nominal species. This ancient group has a world-wide distribution that includes among its ranks large and charismatic taxa such as tarantulas, trapdoor spiders, and highly venomous funnel web spiders. Based on past molecular studies using Sanger-sequencing approaches, numerous mygalomorph families (e.g., Hexathelidae, Ctenizidae, Cyrtaucheniidae, Dipluridae and Nemesiidae) have been identified as non-monophyletic. However, these data were unable to sufficiently resolve the higher-level (intra- and interfamilial) relationships such that the necessary changes in classification could be made with confidence. Here we present a comprehensive phylogenomic treatment of the spider infraorder Mygalomorphae. We employ 472 loci obtained through anchored hybrid enrichment to reconstruct relationships among all the mygalomorph spider families and estimate the timeframe of their diversification.

It didnt last. There were six more of them coming out of the drawers. I batted away two, but the other four landed on my neck and chest. The room was filled with the sounds of me shrieking and crying as I tried to get them off me or kill them or whatever came first. Another one landed on my chest. It was the biggest one Id ever seen; easily 14 inches long and as fat as can of Red Bull. I sobbed as I was forced to grab it in my fist. It bit my hand over and over, causing the worst stinging sensation Id ever experienced. I tried to throw it away, but its legs dug into my wrist and it went nowhere. It kept biting.. As I felt one crawl under my shirt and bite my chest near my left nipple, I punched the area with the fist containing the huge centipede. The midsection of the big one burst against my shirt, killing the one underneath. Thick, orange slime coated my hand, shirt, and had splattered on my face. Now I was able to throw the remains of the big one away and slap and punch at the others ...

... venoms contain toxins that attack our nervous system (neurotoxins), usually by interfering with nerve impulse transmission, so disrupting many of the bodys functions. In extreme cases, this can result in death due to respiratory or circulatory failure.. The widow spiders characteristically spins tangled webs, which look similar to spun cotton candy. Their webs are usually built in or beneath objects close to the ground such as under porches, under foundations of buildings, the lose bark of trees, and in basements. The bite of the black widow is painful and may cause death if medical attention is not sought immediately. Venom. The venom of this spider is highly neurotoxic and respiratory failure can occur if appropriate medications are not administered at once. Fortunately, the black widow is shy and does not bite without great provocation. The spider normally resides in an coarse, irregular web.

BRIGHTON, Mich.) - A Michigan family got more than they bargained for when they bought grapes at a supermarket and found a deadly black widow spider inside.. Callum Merry, 20, noticed a web and spider inside the bag purchased recently at a Kroger in Brighton, Mich. "I looked in the grapes and there was a black widow staring right at me," Merry told ABC News affiliate WXYZ-TV in Detroit.. He wanted to capture the spider and release it into the wild but his brother, Alex Merry, recognized the potential danger.. "I had to physically push him away, take the grapes and put them into a bowl of water to kill it," said Alex, who was also with his mother and sister, 14.. Black widow bites, which can be fatal for small children, can cause muscle aches nausea and paralysis in adults.. ABC News has been unable to reach the family, which is originally from England.. The sister said her instinct would have most likely been to pick up the spider and place it outside if she had found it. "Thats what we usually ...

The clavulanic acid (CLV) is nowadays frequently included in the treatment with Amoxicillin (AX). This component of the antibiotic therapy initially thought to have a low immunogenic capacity; however immediate allergic reactions to CLV have been reported in a 30% of patients allergic to AX-CLV. Basophil activation test (BAT) has shown promising results demonstrating specific recognition of CLV determinants. The aim of this study was to assess the value of BAT in the evaluation of immediate allergic reactions to CLV. ...
RESUMEN. The basophil activation test (BAT) has become a pervasive test for allergic response through the development of flow cytometry, discovery of activation markers such as CD63 and unique markers identifying basophil granulocytes.. Basophil activation test measures basophil response to allergen cross-linking IgE on between 150 and 2000 basophil granulocytes in ,0.1 ml fresh blood. Dichotomous activation is assessed as the fraction of reacting basophils.. In addition to clinical history, skin prick test, and specific IgE determination, BAT can be a part of the diagnostic evaluation of patients with food-, insect venom-, and drug allergy and chronic urticaria. It may be helpful in determining the clinically relevant allergen.. Basophil sensitivity may be used to monitor patients on allergen immunotherapy, anti-IgE treatment or in the natural resolution of allergy. Basophil activation test may use fewer resources and be more reproducible than challenge testing. As it is less stressful for the ...

  • Like other venomous animals such as snakes, scorpions, and spiders, the venom of centipedes could be an excellent source of peptides for developing drugs for treatments as well as bio-insecticides for agrochemical applications. (mdpi.com)
  • Venom from predators including reduviids has been a great source of novel peptides with a notable potential for agricultural and medicinal use. (scielo.br)
  • Most research on venoms has focused on the identification, isolation and purification of proteins and peptides with pharmacological activity like neurotoxins (8, 20, 22) and antimicrobial peptides, whose presence in the venom has been suggested to be a defense mechanism against infections arisen during ingestion of the prey (29, 30). (scielo.br)
  • The presence of these antimicrobial peptides in venom has been suggested to be a defense mechanism against infections that may arise with the ingestion of prey (30). (scielo.br)
  • Snake venoms are complex mixtures of inorganic and organic components, mainly proteins and peptides. (biomedcentral.com)
  • Despite signifying pharmacological importance, very little is known about the active components of centipede venoms. (mdpi.com)
  • Although centipede venoms are yet to be adequately studied, the venom of centipedes as well as their components described to date, should be compiled to help further research. (mdpi.com)
  • The chemical composition of centipede venom is still virtually unknown. (phrygane.tk)
  • Many are associates of other arthropods (Bischoff de Alzuet 1978, Mauri and Bischoff de Alzuet 1972) in various ways, as parasites, predators, and consumers of exudates from the host. (phrygane.tk)
  • The present review brings together data on venomous caterpillars of moths, primarily addressing the available literature on diversity among the different families that cause accident in humans, the structures used in their defense, venom composition and clinical aspects of the envenomations. (nih.gov)
  • Centipedes (Kaestner 1968: 356-388, Lewis 1981) are slender, very elongate, and many segmented arthropods, resembling millipedes only in a very general way. (phrygane.tk)
  • Both C. brevipennis (90.91%) and R. marginatus (45.45%) venoms were more effective against Gram-negative bacteria (80% and 70% for R. marginatus and C. brevipennis , respectively). (scielo.br)
  • For the predator, it may be advantageous to prey using venom with antimicrobial factors, which could help to protect immunocompromised preys from opportunistic pathogens. (scielo.br)
  • We detected the antibacterial activity of R. marginatus and C. brevipennis venoms against seven Gram-negative and four Gram-positive bacteria by using the disc diffusion method. (scielo.br)
  • Rhynocoris marginatus venom exhibited antibacterial activity against four Gram-negative bacteria ( Escherichia coli , Pseudomonas aeruginosa , Proteus vulgaris , Salmonella typhimurium ) and one Gram-positive ( Streptococcus pyogenes ). (scielo.br)
  • As far as we are aware, antibacterial activity in reduviid venom has not been reported. (scielo.br)
