The class Insecta, in the phylum ARTHROPODA, whose members are characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth; several hundred thousand different kinds having been described. Three orders, HEMIPTERA; DIPTERA; and SIPHONAPTERA; are of medical interest in that they cause disease in humans and animals. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p1)
An alpha-adrenergic sympathomimetic amine, biosynthesized from tyramine in the CNS and platelets and also in invertebrate nervous systems. It is used to treat hypotension and as a cardiotonic. The natural D(-) form is more potent than the L(+) form in producing cardiovascular adrenergic responses. It is also a neurotransmitter in some invertebrates.
A group of islands in the southwest Pacific. Its capital is Wellington. It was discovered by the Dutch explorer Abel Tasman in 1642 and circumnavigated by Cook in 1769. Colonized in 1840 by the New Zealand Company, it became a British crown colony in 1840 until 1907 when colonial status was terminated. New Zealand is a partly anglicized form of the original Dutch name Nieuw Zeeland, new sea land, possibly with reference to the Dutch province of Zeeland.

Management of Irukandji syndrome in northern Australia. (1/30)INTRODUCTION: Irukandji syndrome, a potentially life-threatening condition that follows the sting of small carybdeid jellyfish, occurs along the northern Australian coastline from Broome, Western Australia in the west to Rockhampton, Queensland in the east. Much of this area is classified rural or remote. Because correct patient management is essential to avoid unnecessary fatality, and stings are relatively uncommon in any specific location, it was considered important to document current approaches to Irukandji syndrome management throughout coastal northern Australia, comparing urban and more rural health facilities, and to assess the availability of management guidelines for health staff. METHODS: A telephone survey of the clinicians responsible for Irukandji syndrome patient management at 34 coastal northern Australian health facilities that might encounter this patient presentation was conducted during November and December 2003. Healthcare providers responsible for Irukandji syndrome management on the day of survey were interviewed using a structured, standardized questionnaire, which included a description of a hypothetical patient with Irukandji syndrome. This was used to stimulate a spontaneous description of the usual response of the particular health facility to such a patient presentation. Additional vignettes were used to investigate further specific aspects of patient management, including first aid, and pain and blood pressure management. Respondents were also asked about the existence of Irukandji treatment guidelines at their facility. RESULTS: All 34 facilities contacted agreed to participate. Five health facilities were in urban centres with a population of 50,000 or greater, four were within 50 km of such centres, 20 were more remote and five facilities were on islands. Basic clinical monitoring (blood pressure, pulse, respiratory rate and oxygen saturation) was generally adequately practised. Topical application of vinegar as a first aid measure was described by 79% of respondents, with spontaneous mention of vinegar significantly associated with increasing remoteness (p = 0.023). Other sting site management was variable, with uncertainty about the use of pressure immobilisation bandaging. Intravenous opiate analgesia was administered at 91% of facilities, and magnesium sulphate, a treatment that is still being evaluated for its role in Irukandji syndrome-related pain and hypertension, was mentioned by 12% of respondents for pain relief. Twelve different pharmacological treatments were used for syndrome-associated hypertension, with magnesium sulphate being mentioned by 21% of respondents. Of the 22 facilities with guidelines, 14 used either the Primary Clinical Care Manual or the Central Australian Rural Practitioners Association Standard Treatment Manual. The remaining guidelines were independently produced protocols. The availability of guidelines was associated with appropriate use of intravenous opiate for adequate pain relief (p = 0.037). Although all urban health centres and 75% of health facilities <50 km away had guidelines, only 56% of more remote or island facilities reported the availability of guidelines. CONCLUSIONS: Although monitoring and pain management of patients with Irukandji syndrome were generally appropriate, a variety of inappropriate first aid and hypertension management approaches were found. In general, appropriate practice was associated with the presence of guidelines but, unfortunately, guidelines were less often present in remote health facilities. This is particularly important because the majority of respondents who reported no experience of managing Irukandji syndrome were located in more remote settings. There is a need for uniform, evidence-based guidelines, and mechanisms for effective dissemination of these guidelines with training for all health staff who may be required to manage Irukandji syndrome, particularly in remote areas of northern Australia.

Muscle organization of the cubozoan jellyfish Tripedalia cystophora Conant 1897. (2/30)The musculature of the cubomedusa Tripedalia cystophora was investigated using immunohistochemical staining with an anti-actin antibody and histochemical staining with fluorescent phalloidin. The subumbrella is lined with a sheet of circular, striated muscle that is interrupted at the perradii, and by the nerve ring. The sheet is continuous with circular, striated muscle of the velarium, which turns radially on each face of the four velarial frenula. Perradial strips of smooth muscle run radially from just above the level of the rhopalia into the manubrium and lips. The strips give off perpendicular offshoots that run a short distance in parallel with the circular swim muscle. Musculature of the tentacles and pedalia is longitudinal and limited to the oral side of the pedalia. The pedalial muscle connects with bundles of smooth muscle that runs circularly from the tentacle base well into the subumbrella. The arrangement of striated muscle in the frenula suggests that these structures may function in directional nozzle formation of the velarium during turning. In addition, the perpendicular branching of the radial strips and the circular extensions of pedalial muscle may function in hinge formation to aid bending of the pedalia and tentacles into the subumbrella during feeding and protective responses.

A randomized, controlled field trial for the prevention of jellyfish stings with a topical sting inhibitor. (3/30)BACKGROUND: Jellyfish stings are a common occurrence among ocean goers worldwide with an estimated 150 million envenomations annually. Fatalities and hospitalizations occur annually, particularly in the Indo-Pacific regions. A new topical jellyfish sting inhibitor based on the mucous coating of the clown fish prevents 85% of jellyfish stings in laboratory settings. The field effectiveness is unknown. The objective is to evaluate the field efficacy of the jellyfish sting inhibitor, Safe Sea. METHODS: A double-blind, randomized, placebo-controlled trial occurred at the Dry Tortugas National Park, FL, USA and Sapodilla Cayes, Belize. Participants were healthy volunteers planning to snorkel for 30 to 45 minutes. Ten minutes prior to swimming, each participant was directly observed applying a blinded sample of Safe Sea (Nidaria Technology Ltd, Jordan Valley, Israel) to one side of their body and a blinded sample of Coppertone (Schering-Plough, Kenilworth, NJ, USA) to the contralateral side as placebo control. Masked 26 g samples of both Safe Sea SPF15 and Coppertone SPF15 were provided in identical containers to achieve 2 mg/cm(2) coverage. Sides were randomly chosen by participants. The incidence of jellyfish stings was the main outcome measure. This was assessed by participant interview and examination as subjects exited the water. RESULTS: A total of 82 observed water exposures occurred. Thirteen jellyfish stings occurred during the study period for a 16% incidence. Eleven jellyfish stings occurred with placebo, two with the sting inhibitor, resulting in a relative risk reduction of 82% (95% confidence interval: 21%-96%; p= 0.02). No seabather's eruption or side effects occurred. CONCLUSIONS: Safe Sea is a topical barrier cream effective at preventing >80% jellyfish stings under real-world conditions. (+info)
The spectral sensitivity of the lens eyes of a box jellyfish, Tripedalia cystophora (Conant). (4/30)Box jellyfish, or cubomedusae (class Cubozoa), are unique among the Cnidaria in possessing lens eyes similar in morphology to those of vertebrates and cephalopods. Although these eyes were described over 100 years ago, there has been no work done on their electrophysiological responses to light. We used an electroretinogram (ERG) technique to measure spectral sensitivity of the lens eyes of the Caribbean species Tripedalia cystophora. The cubomedusae have two kinds of lens eyes, the lower and upper lens eyes. We found that both lens eye types have similar spectral sensitivities, which likely result from the presence of a single receptor type containing a single opsin. The peak sensitivity is to blue-green light. Visual pigment template fits indicate a vitamin A-1 based opsin with peak sensitivity near 500 nm for both eye types. (+info)
Visually guided obstacle avoidance in the box jellyfish Tripedalia cystophora and Chiropsella bronzie. (5/30)Box jellyfish, cubomedusae, possess an impressive total of 24 eyes of four morphologically different types. Two of these eye types, called the upper and lower lens eyes, are camera-type eyes with spherical fish-like lenses. Compared with other cnidarians, cubomedusae also have an elaborate behavioral repertoire, which seems to be predominantly visually guided. Still, positive phototaxis is the only behavior described so far that is likely to be correlated with the eyes. We have explored the obstacle avoidance response of the Caribbean species Tripedalia cystophora and the Australian species Chiropsella bronzie in a flow chamber. Our results show that obstacle avoidance is visually guided. Avoidance behavior is triggered when the obstacle takes up a certain angle in the visual field. The results do not allow conclusions on whether color vision is involved but the strength of the response had a tendency to follow the intensity contrast between the obstacle and the surroundings (chamber walls). In the flow chamber Tripedalia cystophora displayed a stronger obstacle avoidance response than Chiropsella bronzie since they had less contact with the obstacles. This seems to follow differences in their habitats. (+info)

Preliminary observations on the response of Chironex fleckeri (Cnidaria: Cubozoa: Chirodropida) to different colors of light. (8/30)Cubozoans are well known for their attraction to light and light-colored objects. Two highly venomous types are a public safety concern in Australian waters and elsewhere: Chironex fleckeri, long considered the world's deadliest animal and colloquially called the box jellyfish; and the irukandjis, a group of at least 10 species that cause various degrees of debilitating illness. We were asked by the tourism industry whether there might be a color of light that box jellyfish and irukandjis are not attracted to, such that nighttime diving activities might pose less risk of being stung. Our preliminary trials with Chironex fleckeri indicated a marked positive response to lights of white, red, yellow, green, orange, and blue. All colors elicited a strong and directed attraction to light; however, medusae slowed down their pulsation rate, streamed out their tentacles, and performed a series of figure-eight patterns back and forth through the lighted area when exposed to blue light, which we interpreted as feeding behavior. This compares curiously with a report subsequent to our testing, in which the small, mangrove-inhabiting cubomedusa Tripedalia cystophora and the beach-dwelling Chiropsella bronzie demonstrate a peak sensitivity to blue-green light in the region of 500 nm, and that the former is behaviorally attracted to blue and green light, but ignores red. This leaves open the possibility that Irukandji species, which are more closely related to Tripedalia than to Chironex, may be blind to red. (+info)

Box jellyfish - Wikipedia
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their cube-shaped medusae. Some species of box jellyfish produce extremely potent venom: Chironex fleckeri, Carukia barnesi and Malo kingi. Stings from these and a few other species in the class are extremely painful and can be fatal to humans. Box jellyfish and sea wasp are common names for the highly venomous Chironex fleckeri. However, these terms are ambiguous, as sea wasp and marine stinger are sometimes used to refer to other jellyfish. The medusa form of a box jellyfish has a squarish, box-like bell. From each of the four lower corners of this hangs a short pedalium or stalk which bears one or more long, slender, hollow tentacles. The rim of the bell is folded inwards to form a shelf known as a velarium which restricts the bells aperture and creates a powerful jet when the bell pulsates. As a result, box jellyfish can move more rapidly than other jellyfish; speeds of up to six meters per minute have been ...

Bell and trailing tentacles of a box jellyfish (Cubozoa). Box jellyfish are relatives of true jellyfish, but have a cubic bell and tentacles extending from each lower corner. Unlike true jellyfish they have complex eyes and are active swimmers, avoiding obstacles and chasing after prey. They feed mainly on small fish, which they catch with their stinging tentacles. Some species of box jellyfish have a sting that is rapidly fatal to humans. Filmed in the Gulf of Thailand, near Koh Pha Ngan Island. - Stock Video Clip K004/8614
Box jellyfish larva stage (Carybdea alata), SEM - Stock Image C032/4164 - Science Photo Library
Coloured scanning electron micrograph (SEM) of Larva stage (planula) of a box jellyfish (Carybdea alata). This box jellyfish belongs to the Cubozoa group of Cnidarians. The larval stage of Cnidarians is called the planula and it is a free swimming developmental stage. Cubozoan planulae are pear-shaped, have pigment spots that may be sensitive to light, and swim for a few days using cilia. After a planula settles, it grows into a polyp. The cubozoan polyp can crawl around and bud off more polyps. Like all cnidarians, cubozoans possess nematocysts, cells that fire a barb and transfer venom. When a nematocyst contacts something that might be prey or predator, the barb uncoils and fires from the capsule along with toxic venom.

Chironex fleckeri - Wikipedia
Chironex fleckeri, commonly known as the sea wasp, is a species of highly venomous box jellyfish found in coastal waters from northern Australia and New Guinea north to the Philippines and Vietnam. It has been described as the most lethal jellyfish in the world, with at least 63 known deaths in Australia from 1884 to 1996. Notorious for its sting, C. fleckeri has tentacles up to 3 m (10 ft) long covered with millions of cnidocytes which, on contact, release microscopic darts delivering an extremely powerful venom. Being stung commonly results in excruciating pain, and if the sting area is significant, an untreated victim may die in two to five minutes. The amount of venom in one animal is said to be enough to kill 60 adult humans, although most stings are mild and do not require hospitalization. Chironex fleckeri was named after North Queensland toxicologist and radiologist Doctor Hugo Flecker. On January 20, 1955, when a 5-year-old boy died after being stung in shallow water at Cardwell, ...
Inside the Eye: Natures Most Exquisite Creation | UPRISER
This box jellyfish (Tripedalia cystophora) is only about half an inch across, yet it possesses 24 eyes, housed in four rhopalia. Four of the six eyes in each rhopalium (left) are simple photo sensors, but two have light-focusing lenses. A floating crystal weight called a statolith keeps the top lensed eye always pointing upward, scanning for mangrove canopies that signal food and shelter.. The box jellyfishs eyes are part of an almost endless variation of eyes in the animal kingdom. Some see only in black and white; others perceive the full rainbow and beyond, to forms of light invisible to our eyes. Some cant even gauge the direction of incoming light; others can spot running prey miles away. The smallest animal eyes, adorning the heads of fairy wasps, are barely bigger than an amoeba; the biggest are the size of dinner plates, and belong to gigantic squid species. The squids eye, like ours, works as a camera does, with a single lens focusing light onto a single retina, full of ...

Unlike many jellyfish, the multiple-tentacled box jellyfish Chironex fleckeri is a fast and agile swimmer and is rarely ever found washed up on beaches. It can swim at up to three knots and manoeuvre around pylons and piers. Although Carukia barnesi is also a box jellyfish, it is not as proficient at swimming as Chironex fleckeri. All cubozoans have eyes so that they can hunt prey and avoid objects in the water. Each jellyfish has 24 eyes clustered into four groups of six on each side of its box-shaped body. There are two types of eye in each cluster two complex eyes similar to human eyes (with retinas, lenses and corneas) and two simple pit eyes and two slit eyes. Although cubozoan jellyfish do not a have a brain (they have neurons concentrated in four nerve centres), recent studies indicate that they can form images ...

Flexibly deployed Pax genes in eye development at the early evolution of animals demonstrated by studies on a hydrozoan...
Pax transcription factors are involved in a variety of developmental processes in bilaterians, including eye development, a role typically assigned to Pax-6. Although no true Pax-6 gene has been found in nonbilateral animals, some jellyfish have eyes with complex structures. In the cubozoan jellyfish Tripedalia, Pax-B, an ortholog of vertebrate Pax-2/5/8, had been proposed as a regulator of eye development. Here we have isolated three Pax genes (Pax-A, Pax-B, and Pax-E) from Cladonema radiatum, a hydrozoan jellyfish with elaborate eyes. Cladonema Pax-A is strongly expressed in the retina, whereas Pax-B and Pax-E are highly expressed in the manubrium, the feeding and reproductive organ. Misexpression of Cladonema Pax-A induces ectopic eyes in Drosophila imaginal discs, whereas Pax-B and Pax-E do not. Furthermore, Cladonema Pax-A paired domain protein directly binds to the 5′ upstream region of eye-specific Cladonema opsin genes, whereas Pax-B does not. Our data suggest that Pax-A, but not Pax-B ...
Cubozoan jellyfish are elusive by nature and as a result many challenges exist with respect to detection, which is of concern considering the threat they pose to humans. The polyps of the deadly Chironex fleckeri represent the longest-lived stage of jellyfish and are the source of medusa (adult form of Chironex fleckeri). However, there is almost no information available on the benthic polyp stages of this species.. This project will apply the innovative genetic technique, environmental DNA (eDNA) sampling to detect Chironex fleckeri polys in the waters off Mapoon in far norther Queensland. Should this technique prove successful it will remove the need to physically observe jellyfish in a location and will allow for quicker and increased detection. The study also allows for investigation into the ecology of the polyp life history stage of this jellyfish which currently, is almost unknown.. Further, oceanographic modelling, that incorporates the decay of eDNA, will provide greater knowledge of ...
Eye Development in the Cubozoan Jellyfish Carybdea Marsupialis, ASU NC DOCKS (North Carolina Digital Online Collection of...
Abstract: Cnidarians are the most primitive invertebrates alive today to possess eyes. The complex eyes of the cubozoan jellyfish Carybdea marsupialis exhibit many similarities to the camera-type eyes of higher metazoans including the presence of a cornea, lens, and retina of ciliated photoreceptors. It is these similarities that make understanding the evolution and development of eyes in basal cnidarians important, as they may lead to a better understanding of eye evolution. During the transformation of the polyp to the eye-bearing medusa, the development and arrangement of several components were followed including the neuropeptide FMRFamide, UV opsin-like protein (indicates photoreceptor formation), J1-crystallin (indicates lens formation), and shielding pigment formation. The first ocelli to appear were the complex eyes followed by the simple ocelli; the small complex eye was the first to exhibit pigment formation (melanin) as well as photoreceptor maturation. J1-crystallin was located in ...

SICB - 2012 meeting - Abstract Details
Box Jellyfish (Class: Cubozoa) are strong, active swimmers capable of evading hazardous obstacles and orienting to photic stimuli. Directional swimming is accompanied by asymmetric deformations of the velarium, a striated muscle sheet encircling the bell opening. Radial, buttress-like muscles, termed frenula, are presently thought to serve only a stabilizing structural role during swimming. We hypothesize the frenula serve a greater function in turning behavior than previously thought. During a turning event, frenular contractions in the radial axis result in shortening of the bell height as the velarium is pulled upward towards the bell apex. Asymmetrical contractions would produce directional fluid ejection from the bell opening, which would propel the medusa into a turn. To investigate this behavior confocal-light microscopy, electron microscopy, videography and electrophysiological techniques were employed. Our results demonstrate that the frenulum is the most densely-innervated swim muscle ...
Thinking Inside The Box: Insights Into One Of The Worlds Deadliest Venoms - Science Sushi
When you get right down to it, box jellyfish are little more than goo. The majority of their volume is mesoglea, a non-living, jello-like substance, which is sandwiched between two thin tissue layers. They have no teeth to bite with, no claws to scratch with - none of the weaponry we generally think of when we imagine a ruthless predator. Yet these boneless, brainless boxies are among the deadliest animals on Earth. The box jellyfish Chironex fleckeri can kill a full grown man in less than five minutes, and the venom it wields in its tentacles contains of some of the most rapid, potent toxins in the world.. Exactly what those toxins are, though, has remained somewhat of a mystery. Scientists have been trying to determine the composition of box jelly venom for decades, but have only uncovered some of its potent constituents. And while theres still more to learn, last week, a research team from Queensland, Australia published the most extensive analysis of Chironex venom proteins to date, ...

Background: Despite recent deaths caused by box jellyfish envenomation occurring on the islands of Samui and Pha-ngan in the Gulf of Thailand, many people do not believe box jellyfish can kill humans and many people dismiss the problem as insignificant. More evidence has been requested from the communities in order to evaluate the need for and the implementation of sustainable prevention measures. We aimed to determine the magnitude of cases of severe stinging by box jellyfish and describe the characteristics of these cases on the islands of Samui and Pha-ngan in Surat Thani Province from 1997 to 2015.

Science Pal: Jellyfish and human eyes assembled using similar genetic building blocks
When Kozmik looked for box jellyfish genes that are involved in sight, he found that their opsin protein is also similar to the versions found in vertebrate eyes. With further tests, Kozmik confirmed that the jellyfishs opsin is a fully functioning visual protein. It sticks to retinal and is particularly sensitive to blue-green light. The similarities didnt stop there. Kozmik found that the chain of proteins that carry the message passed on by opsin, are again similar to those used by vertebrates. And just as our eyes use the dark pigment melanin, so do those of the box jellyfish. Amid its genome, Kozmik found the jellyfish versions of human gene called Oca2 and Mitf that are essential for creating melanin. The genes are switched on in a part of the jellyfish eye thats littered with granules of pigment, which were identified as melanin through chemical tests. Parallel or conserved? Despite the massive evolutionary gulf that separates jellyfish and vertebrates, both groups construct their eyes ...

Most recent papers with the keyword Irukandji | Read by QxMD
The potentially fatal Irukandji syndrome is relatively common in tropical waters throughout the world. It is caused by the sting of the Irukandji jellyfish, a family of box jellyfish that are almost impossible to detect in the water owing to their small size and transparency. Using collated medical records of stings and local weather conditions, we show that the presence of Irukandji blooms in coastal waters can be forecast on the basis of wind conditions. On the Great Barrier Reef, blooms largely coincide with relaxation of the prevailing southeasterly trade winds, with average conditions corresponding to near zero alongshore wind on the day prior to the sting ...

Generally, we will recommend a contact lens trial whenever trying a new lens on a person for the first time, as this allows a person to experience how the lenses will perform before purchasing a supply of lenses. It also gives us the opportunity, at the follow-up appointment, to evaluate the lenses to maximize the clarity of vision through the lenses, and make sure there are no adverse effects to the eye health.. When there is astigmatism in your vision, we use special techniques to create the clearest possible vision with special lenses for astigmatism called toric lenses. The result: is vision that many people find to be clearer than they have ever had before with contact lenses.. ...

Some Facts About Jellies You Never Knew
The sea wasp (chironex fleckeri) is a lethally dangerous jelly living in northern Australias coastal waters. The amount of venom in one animal is considered to be enough to kill 60 adults. For the past 100 years the Sea Wasp jellies caused the death of about 100 people, and now it can be considered one of the most dangerous sea creatures. Those jellyfish can grow to the size of a basketball ball. Their tentacles are about 15 cm long and 5 mm in diameter, but when they hunt the tentacles become thinner and their length extends to about 3 meters long. Because of its colors (light-blue) it is really hard to see it in the water and that makes it even more dangerous. The string of the Sea Wasp is extremely painful with an intense burning sensation. The venom affects the nervous system, heart, and skin at the same time. A human can die from a sting of a Sea Wasp in 3-5 minutes. Despite the fact that there is an antidote, the timely treatment of the victim may be impossible. Frequently, a stung person ...

Breastcancer.org provides an invaluable opportunity to inform women about these imaging ...
Proceedings of the Royal Society of London B: Biological Sciences
In general, cubozoan distributions are not well documented on intermediate geographical scales (e.g. provinces, states or countries) owing to a lack of sampling, which hampers biogeographic enquiries at this scale (see Bentlage et al. 2009 for a possible strategy to address this issue). However, on larger scales (e.g. ocean basins) several patterns emerge in light of our results. In particular, we uncovered numerous deep divergences among Indo-Pacific and Atlantic clades (figure 1). In Chirodropida, the genus Chiropsalmus is exclusively Atlantic, whereas the confamilial Chiropsella is from the Indo-Pacific groups with the exclusively Indo-Pacific Chironex (family Chirodropidae). Similarly, what had been recognized as Tamoyidae (Tamoyidae sens. nov. plus Carukiidae) can also be divided geographically: Tamoyidae is restricted to the Atlantic and the described species of Carukiidae are known from Australia and Japan, but probably range throughout the Indo-Pacific (Cleland & Southcott 1965; B. ...
Real Monstrosities: Irukandji Jellyfish
Irukandji syndrome is caused by the jellyfishs sting. At first it feels like little more than a mosquito bite, but the symptoms grow increasingly severe over the next 30 minutes or so. Eventually there are severe pains and headaches, terrible cramps in the arms and legs, sweating, vomiting, increase in heart rate and blood pressure, and even a feeling of impending doom ...
Obstacle avoidance in persons with rheumatoid arthritis walking on a treadmill.
OBJECTIVE:Patients with rheumatoid arthritis (RA) are at increased risk of falling. In healthy elderly persons with a history of falling, a reduced ability to avoid obstacles while walking has been shown to relate to increased fall risk. The aim of this study was to determine whether this potential risk factor for falls would also be present in persons with RA.METHODS:Twelve RA patients and twelve controls performed an obstacle avoidance task on a treadmill. The obstacle was released during three different phases of the gait cycle (late stance, early swing and mid swing) to create increasing difficulty levels. The primary outcome measure was failure rate.RESULTS:Overall, the RA patients had significantly higher obstacle avoidance failure rates. To avoid an obstacle, a long or a short stride strategy can be used, the choice of which depends on the phase of obstacle release. There were no significant group differences in the distribution of obstacle avoidance strategies. However, the RA patients ...
Patent US5715031 - Concentric aspheric multifocal lens designs - Google Patents
Concentric aspheric multifocal lens designs are disclosed which use a combination of an aspheric front surface, which results in aberration reduction and contrast vision enhancement, along with a concentric multifocal back surface, to produce a lens design which affords clear vision at a distance and also near without a loss in contrast which is generally typical of prior art simultaneous vision, concentric multifocal lens designs. The aspheric surface improves the modulation transfer function (MTF) of the lens eye combination which improves the focus and contrast of both distance and near images. The design form is valid for contact lenses and intraocular lenses.

Indian Journal of Dermatology, Venereology and Leprology - Jellyfish dermatitis
Secondary reactivation may be related to high anti-jellyfish immunoglobulin levels, intracutaneously sequestered antigen, or cross reacting venom. . If the jellyfish is of a dangerous variety (Indo-Pacific box jellyfish) or if the victim is exposed to a large amount of nematocysts, systemic manifestations like shock, angioedema, dizziness and muscle spasms can occur, with risk of drowning. A less common but serious complication of stings over the extremities is peripheral arterial spasm and compartment syndrome threatening limb viability.. First aid for jellyfish sting includes immediately getting the victim out of the sea and washing the affected area with sea water to remove tentacles. Soaking the affected area in hot water (40°C) will denature the nematocyst and its venom. Topical ice packs and vinegar have also been recommended as first aid for pain relief. Topical corticosteroid and antihistamine drugs can be used for immediate and delayed cutaneous reactions. Topical calcineurin ...

TY - JOUR. T1 - An examination of the cardiovascular effects of an Irukandji jellyfish, Alatina nr mordens. AU - Winter, Kelly. AU - Isbister, Geoffrey. AU - Schneider, Jennifer. AU - Konstantakopoulos, Nicki. AU - SEYMOUR, J. AU - Hodgson, Wayne. PY - 2008. Y1 - 2008. N2 - Irukandji syndrome is usually characterized by delayed severe abdominal, back and chest pain associated with autonomic effects including diaphoresis, hypertension and, in severe cases, myocardial injury and pulmonary oedema. It is most often associated with envenoming by the jellyfish Carukia barnesi, but a number of other jellyfish, including Alatina mordens, are now known to produce Irukandji syndrome. In the present study, nematocyst-derived venom from A. nr mordens (150-250 ?g/kg, i.v.) produced a long-lasting pressor effect in anaesthetised rats. This pressor response (250 ?g/kg, i.v.) was significantly inhibited by prior administration of the ?-adrenoceptor antagonist prazosin (200 ?g/kg, i.v.) but not by CSL box ...
Jellyfish are fascinating creatures. They are so fascinating, they have even made it into a few video games. Granted, these games seem to be obsessed with portraying them as creatures which mysteriously float in the air, rather than swim in the sea, but even so, it shows how jellyfish capture the imagination. The reality is actually just as interesting, with actual jellyfish which are just as deadly as any found on a game - and sometimes even deadlier.. Take the box jellyfish, for instance: these sea creatures are roughly square, with four distinct sides. (This in itself is unusual, since nature seems to favor round or ovoid shapes.) Each side of the cube can be as long as almost 8 inches, and each corner can have up to 15 tentacles on it. Each tentacle can be as long as 10 feet. But the deadliness lies in the 5000 stinging cells on each tentacle. The stinging is not triggered by touch - it is actually triggered by the chemicals in the skin or exoskeleton of the prey. Therefore, it is very hard ...

Jellyfish stings: urine is not the answer
The jellyfish are coming!. According to the Marine Conservation Society, increasing numbers of jellyfish - presumably encouraged by the hot weather - are currently bobbing along Britains coastline.. This probably means many bathers will be having a painful aquatic encounter in the next couple of weeks - and some unlucky punters will probably get treated in a novel way.. Help on tap. Thats because lots of people still believe its a good idea to wee on someone whos been stung by a jellyfish.. Bizarre as it sounds, this is true. As temperatures soar this weekend, hundreds of British beachgoers will have their hands poised on their zippers, gunslinger-style, ready to pull down at a moments notice and help anyone running from the water in pain.. Dangerous cure. The hoary old myth that urinating on jellyfish stings lessens the pain is still surprisingly popular in the UK, despite medically making no sense at all. (Really, think about it.

Freshwater Jellyfish - Moshawquit Lake
The freshwater jellyfish found in Wisconsin are one of several species of Craspedacusta native to China. Two species (C. sowerbii and C. sinensis) live in the Yangtze River - the worlds third longest river and one so vast it makes the Wisconsin River seem like a trout stream! Freshwater jellyfish were first reported in North America as early as 1884. Sightings in Wisconsin date back to 1969. Much more remains to be learned about these fascinating creatures. Although they probably evolved from estuarine species, themselves descendents of ocean jellyfish, little is known about the evolution of freshwater jellyfish.

What Does It Take to Make a Jellyfish? | The Institute for Creation Research
Many jellyfish are transparent, and they have seemingly simple movements and few visible interacting parts. They should, therefore, be easy to synthesize with man-made parts, but thats not what bioengineers discovered when they recently built a jellyfish mimic from rat heart cells attached to a silicone frame.. A team of Unites States collaborators produced a structure that, when energized by an external electrical shock, flexed and moved like a jellyfish in a water tank. Nature News posted a video showing their construct in motion.1. Just what hurdles did the research team overcome in order to achieve their modest results?. The bioengineers used a systematic design strategy to reverse engineer a muscular pump, according to the technical report in Nature Biotechnology. They also wrote, The constructs, termed medusoids, were designed with computer simulations and experiments to match key determinants of jellyfish propulsion and feeding performance by quantitatively mimicking structural ...

Jellyfish replacing fish in over-exploited areas
(PhysOrg.com) -- Over-fished commercial stocks of plankton-eating fish have been replaced in several locations by jellyfish species. This appears to be something of a paradox because fish move quickly and can see their prey, which suggests their capture of prey should be much more efficient than for jellyfish that move slowly and have to make contact with their prey to know they are present. Now a team of scientists in Spain and the US have discovered he jellyfishes success is partly based on their large body size and its energy efficiency.

Follow Me to France...: The Final Chapter
At 6 ½ hours I swam through a large swarm of jellyfish. They were blue, purple and yellow and of all different sizes. They were on the surface of the water and as deep as about 5 feet. The water was clear by now and all that I could see was jellyfish in every direction. This lasted for about 30-45 minutes. My crew carefully pointed out the path I should follow. Sometimes the space between two jellies was too close for me to swim and I would make my body as narrow as possible and skull and kick as I made my way through. I swam with my head up and my eyes at the surface of the water. I picked up my head enough to loudly should expletives at the jellies. Something worked because I managed to make my way through hundreds of jellyfish without getting stung. I had gotten a small sting earlier, but nothing during that time. For the next several hours I watched as my dad diligently studied the water making sure I didnt swim into any more jellies. I imagined that they seagulls were above were watching ...

Lower-Middle Classroom | by Edgar Z. Friedenberg | The New York Review of Books
Dr. Conants new book sets a high stylistic standard for administrative documents. It is bland, slightly tart, and absolutely clear; at times lightly personal, never contentious, often convincing. Its calm and precision are surgical; the surgery proposed, however, is not radical, but extensive and superficial.. This superficiality is a consequence of Dr. Conants conception of the subject as an administrative problem, rather than a moral and social one. Indeed, within this framework he could not have done more, nor done it more scrupulously. He and his collaborators spent a year of a two-year study visiting seventy-seven colleges and universities in twenty-two states. These schools graduated in 1962 27 per cent of the teachers granted degrees in those states, or about one-fifth of all the teachers graduated in the country. Dr. Conant himself visited fifty-two of these institutions, including the one in whose Department of Education I was teaching at the time. I remember very clearly the care ...
Nowadays, robots interact more frequently with a dynamic environment outside limited manufacturing sites and in close proximity with humans. Thus, safety of motion and obstacle avoidance are vital safety features of such robots. We formally study two safety properties of avoiding both stationary and moving obstacles: (i) passive safety, which ensures that no collisions can happen while the robot moves, and (ii) the stronger passive friendly safety in which the robot further maintains sufficient maneuvering distance for obstacles to avoid collision as well. We use hybrid system models and theorem proving techniques that describe and formally verify the robots discrete control decisions along with its continuous, physical motion. Moreover, we formally prove that safety can still be guaranteed despite location and actuator uncertainty ...
