Contribution to the knowledge of echinoid fauna from Persian Gulf (Echinodermata: Echinoidea) [PDF]
Iranian Journal of Animal Biosystematics, 2016 Species identification is always important. Records of sea urchins and sand dollars species (Echinodermata, Echinoidea) is given from Iranian waters. Nine Species of Echinoderms were identified through the study.

Radial Glia in Echinoderms [PDF]
Developmental Neurobiology, 2018 AbstractRadial glial cells are crucial in vertebrate neural development and regeneration. It has been recently proposed that this neurogenic cell type might be older than the chordate lineage itself and might have been present in the last common deuterostome ancestor.

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.ABSTRACT Resistance to chemotherapy, which is demonstrated in almost every patient with advanced‐stage lung cancer (ALC), underscores an urgent need to unravel the underlying molecular mechanisms and identify novel strategies to overcome drug resistance. In the present study, an attempt was made to identify epigenetic targets and modulators that can be

Molecular approach to echinoderm regeneration [PDF]
, 2001 Until very recently echinoderm regeneration research and indeed echinoderm research in general has suffered because of the lack of critical mass. In terms of molecular studies of regeneration, echinoderms in particular have lagged behind other groups in ...

Molecular paleobiology of the echinoderm skeleton [PDF]
Molecular paleobiology provides a promising avenue to merge data from deep time, molecular biology and genomics, gaining insights into the evolutionary process at multiple levels. The echinoderm skeleton is a model for molecular paleobioloogical studies.

Sea Urchins as an Inspiration for Robotic Designs
Journal of Marine Science and Engineering, 2018 Neuromorphic engineering is the approach to intelligent machine design inspired by nature. Here, we outline possible robotic design principles derived from the neural and motor systems of sea urchins (Echinoida).

The Depositional Record, Volume 12, Issue 4, September 2026.An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Electron microprobe study of magnesium distribution in some Mississippian echinoderm limestones from western Canada [PDF]
, 1970 Electron microprobe techniques were used to examine the distribution of Mg, Ca, and Fe in six samples of Mississippian skeletal and oölitic limestones from the Alberta Rocky Mountains. All samples show extremely low values of Fe.

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters
New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...
