Biochemical characterization and antibacterial activity of lipopolysaccharide binding proteins of the jellyfish Aurelia aurita and Rhopilema asamushi.

Fish and Shellfish Immunology
Proteins capable of binding lipopolysaccharides (LPSs) of Gram-negative bacteria were isolated from the jellyfish of the Sea of Japan. LPS-binding proteins (ILBP - invertebrate lipopolysaccharide-binding proteins) were found in lysates of the jellyfish ...

Influence of in situ temperature and maternal provisioning on the medusa-to-polyp transition in a year-round population of the scyphozoan Aurelia aurita

Journal of the Marine Biological Association of the United Kingdom
We investigated how environmental conditions translate into reproductive success or failure in Aurelia aurita from the medusa to the polyp life stage.

Aurelia aurita–Cnidarian with a prominent medusiod stage

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2011
AbstractAurelia aurita has a complex life cycle that consists of several stages including alternating generations of medusa and polyps, huge sexual, and tiny asexual stages. Cnidarian is thought to possess two tissue layers: endoderm (gastroderm) and ectoderm, which are separated by mesoglea in medusa.

Fine structure of touch-plates in the scyphomedusan Aurelia aurita

Journal of Ultrastructure Research, 1982
The organ by which Aurelia aurita senses the direction of gravity consists of a statolith and an epithelial “touch-plate.” The latter comprises three types of receptor cells. Type I , a receptor cell with one sensory hair encircled by microvilli, an apical aggregation of vacuoles, and a basal neurite.

Evaluating yield of DNA extraction methods across different tissues of moon jellyfish Aurelia aurita (Linnaeus, 1758)

Biological Diversity and Conservation
Purpose: This study aimed to optimize DNA extraction from the moon jellyfish Aurelia aurita, a gelatinous marine invertebrate, by comparing different methodologies and evaluating the influence of tissue type and Proteinase K treatment duration on DNA ...

On the Variation of the Tentaculocysts of Aurelia aurita

Journal of Cell Science, 1895
ABSTRACT It was a suggestion from Professor Weldon that led me to examine a large number of specimens of the ephyræ and adult stage of Aurelia aurita for the purpose of finding out the variation in the number of tentaculocysts, and if a variation occurred among the ephyræ to see how far it affected the adults.

Chemoreception in Aurelia aurita studied by AI-enhanced image analysis

Journal of emerging investigators
Jellyfish have not significantly changed in anatomy or physiology for over 500 million years. Their nervous system offers valuable insights into the function and evolution of more complex systems.

Observations concerning the metabolism of iodine by polyps of Aurelia aurita

General and Comparative Endocrinology, 1978
In the Scyphozoan jellyfish, Aurelia aurita, iodine is necessary for, and capable of initiating, the process of strobilation, by which the sessile polyp is transformed into the free-swimming medusa. Iodine metabolism in polyps of Aurelia aurita was studied, therefore, with a view to elucidating its role in the initiation of strobilation.

Light as an Inhibitor of Strobilation in Aurelia aurita

Nature, 1964
THE environmental conditions under which strobilation of Aurelia scyphistomae occurs are incompletely understood. Berrill1 in a review suggests three factors as being of particular significance: a heavy diet of suitable food prior to metamorphosis; a definite, low critical temperature, usually the winter minimum; and a good supply of food and oxygen at

The Effects of X Irradiation on the Metamorphosis and Budding of Aurelia aurita

Radiation Research, 1990
With the aid of the Aurelia metamorphosis test system, the acute and subtle developmental and behavioral effects of X irradiation in the presence and absence of thyroxine on the Norfolk Aurelia aurita were described. Radiation doses were 0 (control), 50, 100, 150, 200, and 400 Gy.
