We have shown that vesicles in the axoplasm of the squid giant axon move on actin filaments and that movement is inhibited by myosin V-specific antibodies [Tabb et al., 1998]. In the study reported in this article, experiments were performed to clone and sequence the cDNA for squid brain myosin V. Five proteolytic fragments of purified squid brain myosin V were analyzed by direct protein sequen...

Abstract We report on the development of an analytical model describing readout power and superconducting quantum interference device (SQUID) hysteresis parameter dependence resonator characteristics used for frequency encoding in microwave SQUID multiplexers. Within context this model, we derived different dependencies by analyzing Fourier components non-linear response non-hysteretic rf-SQUID...

Hierarchical Web caching has become prevalent throughout the Internet. The popular Squid software has played an important role. We present a short history of Squid and the Internet Cache Protocol, and ooer our thoughts regarding its future evolution.

Allergy to different classes of mollusks, including squid, which are members of the class Cephalopods has been reported. Tropomyosin, a major muscle protein, is the only well-recognized allergen in squid. The aim of this study was to characterize IgE-binding proteins of local Loligo edulis (white squid) consumed in Malaysia. Protein profiles and IgE-binding proteins were detected by sodium dode...

We have used the squid giant synapse to determine whether clathrin assembly by AP180 is important for synaptic vesicle endocytosis. The squid homolog of AP180 encodes a 751 amino acid protein with 40% sequence identity to mouse AP180. Alignment of squid AP180 with other AP180 homologs shows that amino acid identity was highest in the N-terminal inositide-binding domain of the protein and weakes...

Two predominant currents, the warm Kuroshio Current and the cold Oyashio Current, meet in the Northwest Pacif ic Ocean. The interaction of these two currents between the subtropical and subarctic fronts forms a transition region (Roden, 1991). The dynamic of the physical oceanographic structures in this region, including meandering eddies and frontal zones, results in a highly productive habita...

Lobster and squid giant nerve fibers respond differently when subjected to osmotic challenges. The axons proper, as distinct from the total (fiber) complex formed by the axon and connective sheath, both behave as "fast" osmometers for changes in the concentration of NaCI, but the maximum degree of swelling in hyposmotic media is by about 60 % in lobster and only by 20 % in squid. The relative v...

Ontogenetic changes in the organization and volume fraction of collagenous connective tissues were examined in the mantle of Sepioteuthis lessoniana, the oval squid. Outer tunic fiber angle (the angle of a tunic collagen fiber relative to the long axis of the squid) decreased from 33.5 degrees in newly hatched animals to 17.7 degrees in the largest animals studied. The arrangement of intramuscu...

The squid Euprymna scolopes has evolved independent sets of tissues capable of light detection, including a complex eye and a photophore or 'light organ', which houses the luminous bacterial symbiont Vibrio fischeri. As the eye and light organ originate from different embryonic tissues, we examined whether the eye-specification genes, pax6, eya, six, and dac, are shared by these two organs, and...

Recent scientific and anecdotal observations have documented a range expansion of jumbo squid, Dosidicus gigas, into the Southern California Bight (SCB) and northward in the California Current Large Marine Ecosystem. The increase in squid abundance at higher latitudes has generated hypotheses concerning the ecosystem changes that may have permitted this expansion. Top-down explanations suggest ...
