Steroids, 1973
Abstract Starfish Linckia multifora, Protoreaster nodosus, Protoreaster lincki, Culcita schmideliana, Nardoa variolata and Acanthaster planci were examined for sterols and sapogenins. All asteroids contained cholestanol in addition to C 27 to C 30 mono and diunsaturated sterols.

Starfish Saponins, 52. Chemical Constituents from the Starfish Echinaster brasiliensis
Journal of Natural Products, 1993This paper reports an analysis of the chemical constituents from the Caribbean starfish Echinaster brasiliensis collected at Grand Bahama Island. This species is completely devoid of cyclic steroidal glycosides, previously isolated from two species of the genus Echinaster in place of the more common penta- and hexa-glycoside steroidal sulfates ...

This paper improves the price-performance ratio of ECM, the elliptic-curve method of integer factorization. In particular, this paper constructs "a = -1" twisted Edwards curves having Q-torsion group Z/2 x Z/4, Z/8, or Z/6 and having a known non-torsion point; demonstrates that, compared to the curves used in previous ECM implementations, some of the ...

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1951
The fossil starfish described here are mainly from the Lower Ordovician (including the Tremadocian). Only brief descriptions of these starfish have been given previously. They are the earliest starfish known, and arrived in a series of transgressions which began in the Tremadocian and persisted throughout the immediately succeeding beds.

The article offers information on the COTSbot robotic device developed by robotics researchers at Queensland University of Technology in Australia, that aims to stop crown of-thorns starfish (COTS) from destroying the Great Barrier Reef by giving them lethal injections.

Cryopreservation of starfish oocytes
Cryobiology, 2005Research from many laboratories over the past several decades indicates that invertebrate oocytes and eggs are extraordinarily difficult to freeze. Since starfish oocytes, eggs, and embryos are an important cell and developmental biology model system, there is great interest to cryopreserve these cells. Previous starfish oocyte cryopreservation studies

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975
Abstract 1. 1. A preparation from the pyloric caeca of starfishes is essentially a complex mixture of proteolytic enzymes. The preparation contains enzymes similar to carboxypeptidases A and B, leucine aminopeptidases and trypsin; chymotrypsin-, pepsin- and elastase-like enzymes are absent in the preparation. 2. 2.

Proceedings of the Ninth International Conference on Tangible, Embedded, and Embodied Interaction, 2015
In HCI there are attempts to create expressive computing by exploring emotional engagements through a wide range of shape-changing interfaces including experimental art, fashion, architecture, furniture, etc. These approaches range from hedonic design purposes, which represent novel ideas and materials to more informative design spaces, which allow ...
