INTRODUCTION Contact with a jellyfish can cause a wide variety of conditions, ranging from cutaneous eruption to fatal cardiovascular and respiratory collapse. Cutaneous features can be both acute and chronic. We report a case of persistent lichen planus-like eruption in a young boy after a jellyfish sting, a hitherto unreported occurrence. CASE PRESENTATION A 15-year-old boy presented with m...

Ad Hoc networks are susceptible to many attacks due to its unique characteristics such as open network architecture, stringent resource constraints, shared wireless medium and highly dynamic topology. The attacks can be of different types out of which denial of service is one of the most difficult attacks to detect and defend. Jellyfish is a new denial of service attack that exploits the end to...

BACKGROUND Jellyfish stings are common worldwide with an estimated 150 million cases annually, and their stings cause a wide range of clinical manifestations from skin inflammation to cardiovascular and respiratory collapse. No studies on jellyfish stings have been carried out in Basra, Iraq. OBJECTIVES To describe the immediate and delayed skin reactions to White Jellyfish (Rhizostoma sp.) s...

BACKGROUND Jellyfish stings cause painful, papular-urticarial eruptions due to the immediate allergic, acute toxic and persistent inflammatory responses. In spite of many marine accidents and their economic impact, modes of first-aid treatment remain conventional and specific allergen and medical treatment are not yet available. The purpose of this study was to define the specific allergen of t...

The yellow fluorescent protein phiYFPv (λem(max) ≃ 537 nm) with improved folding has been developed from the spectrally identical wild-type phiYFP found in the marine jellyfish Phialidium. The latter fluorescent protein is one of only two known cases of naturally occurring proteins that exhibit emission spectra in the yellow-orange range (535-555 nm). Here, the crystal structure of phiYFPv has ...

Cations have generally been reported to prevent jellyfish venom-induced hemolysis through multiple mechanisms by spectrophotometry. Little attention has been paid to the potential interaction between cations and hemoglobin, potentially influencing the antagonistic effect of cations. Here, we explored the effects of five reported cations, La3+, Mn2+, Zn2+, Cu2+ and Fe2+, on a hemolytic test syst...

Tenacibaculosis is an increasing problem in the Norwegian Atlantic salmon aquaculture industry causing significant economic losses. In September 2015, two separate outbreaks of suspected tenacibaculosis occurred at two Atlantic salmon farms in Finnmark County in Northern Norway. The events resulted in major losses of smolts newly transferred into seawater. Prior to, and during the outbreaks, la...

MANET’s have picked up enthusiasm of analysts in years ago. It is wireless network so that nodes move arbitrarily in the network. Zone routing protocol is kind of hybrid routing protocol. Numerous attackers are attacking on Manet due to its tendency. One attack is Jellyfish reorder attack that reorders the packets during forwarding source to destination node. This paper is subjected to correlat...

Box jellyfish have an impressive set of 24 eyes of four different types, including eyes structurally similar to those of vertebrates and cephalopods [1, 2]. However, the known visual responses are restricted to simple phototaxis, shadow responses, and object avoidance responses [3-8], and it has been a puzzle why they need such a complex set of eyes. Here we report that medusae of the box jelly...

The increasing frequency of jellyfish outbreaks in coastal areas has led to multiple ecological and socio-economic issues, including mass mortalities of farmed fish. We investigated the sensitivity of the European sea bass (Dicentrarchus labrax), a widely cultured fish in the Mediterranean Sea, to the combined stressors of temperature, hypoxia and stings from the jellyfish Pelagia noctiluca, th...
