Iodination of toxin II from the sea anemone Anemonia sulcata gives a labeled monoiododerivative that retains 80% of the original neurotoxicity. This derivative binds specifically to rat brain synaptosomes at 20 degrees C and pH 7.4 with a second-order rate constant of association ka = 4.6 x 10(4) M-1 sec-1 and a first-order rate constant of dissociation kd = 1.1 x 10(-2) sec-1. The binding occu...

Performance of large memory applications degrades rapidly once the system hits the physical memory limit and starts paging to local disk. We present the design, implementation and evaluation of Distributed Anemone (Adaptive Network Memory Engine) – a lightweight and distributed system that pools together the collective memory resources of multiple machines across a gigabit Ethernet LAN. Anemone...

Coronal structure of active regions appearing in coronal holes is studied by using the data obtained with the Soft X-Ray Telescope (SXT) aboard Yohkoh from 1991 November to 1993 March. The following characteristics are found; Many of active regions appearing in coronal holes show a structure that looks like a “sea-anemone”. Such active regions are called anemone ARs. About oneforth of all activ...

Many stony coral-dwelling fishes exhibit adaptations to deal with hypoxia among the branches of their hosts; however, no information exists on the respiratory ecophysiology of obligate fish associates of non-coral organisms such as sea anemones and sponges. This study investigated metabolic and behavioral interactions between two-band anemonefish (Amphiprion bicinctus) and bulb-tentacle sea ane...

The so-called “anemone” solar flares are an interesting type of the space plasma phenomena, where multiple null points magnetic field connected with each other and sources by separators, thereby producing complex branching configurations. Here, using methods dynamical systems Morse–Smale theory, we derive a few universal topological relations between numbers various kinds arbitrary arrangement ...

The effects of polypeptide neurotoxin from Anemonia sulcata on nerve conduction in crayfish giant axons and on frog myelinated fibers have been analyzed. The main features of toxin action are the following: (i) the toxin acts at very low doses and its action is apparently irreversible. (ii) The toxin selectively affects the closing (inactivation) of the Na+ channel by slowing it down considerab...

The sea anemone Stomphia coccinea, when touched by certain starfishes, frees itself from the substratum, and by a series of waving motions propels itself through the water. This locomotion has been studied by means of direct observation and by analysis of time-lapse, and normal-speed motion-picture films. Ecological observations and stimulation tests made in the natural environment of the anemo...
