Beyond the Nature-Culture Frontier

Journal of Festive Studies, 2021
In order to challenge the culture–nature dichotomy, this article investigates two festivities centered around fishing and consuming the sea urchin in two different locations: the Suape Bay Ouriçada (Brazil) in the Southern Hemisphere, and the Carry-le ...

IL17 factors are early regulators in the gut epithelium during inflammatory response to Vibrio in the sea urchin larva

eLife, 2017
IL17 cytokines are central mediators of mammalian immunity. In vertebrates, these factors derive from diverse cellular sources. Sea urchins share a molecular heritage with chordates that includes the IL17 system.

Uncommon southwest swells trigger sea urchin disease outbreaks in Eastern Atlantic archipelagos

Ecology and Evolution, 2020
Recurrent sea urchin mass mortality has recently affected eastern Atlantic populations of the barren‐forming sea urchin Diadema africanum. This new episode of die‐off affords the opportunity to determine common meteorological and oceanographic conditions

Sea urchin roe quality within urchin barrens and improvement through kelp restoration

Ecosphere
Sea urchin overgrazing is a major cause of kelp loss and consequently sea urchin removal is frequently promoted as a tool for restoring kelp in urchin barrens. While many sea urchin species support high‐end roe fisheries, roe condition is generally lower

Single-cell RNA sequencing of the Strongylocentrotus purpuratus larva reveals the blueprint of major cell types and nervous system of a non-chordate deuterostome

eLife, 2021
Identifying the molecular fingerprint of organismal cell types is key for understanding their function and evolution. Here, we use single-cell RNA sequencing (scRNA-seq) to survey the cell types of the sea urchin early pluteus larva, representing an ...

Titanium dioxide nanoparticles stimulate sea urchin immune cell phagocytic activity involving TLR/p38 MAPK-mediated signalling pathway

Scientific Reports, 2015
Titanium dioxide nanoparticles (TiO2NPs) are one of the most widespread-engineered particles in use for drug delivery, cosmetics and electronics. However, TiO2NP safety is still an open issue, even for ethical reasons.

Polysaccharide Constituents of Three Types of Sea Urchin Shells and Their Anti-Inflammatory Activities

Marine Drugs, 2015
As a source of potent anti-inflammatory traditional medicines, the quantitative chromatographic fingerprints of sea urchin shell polysaccharides were well established via pre-column derivatization high performance liquid chromatography (HPLC) analysis ...

The impact of ocean acidification and warming on the skeletal mechanical properties of the sea urchin Paracentrotus lividus from laboratory and field observations

, 2016
Increased atmospheric CO2 concentration is leading to changes in the carbonate chemistry and the temperature of the ocean. The impact of these processes on marine organisms will depend on their ability to cope with those changes, particularly the ...

Spatial and temporal patterns of gene expression during neurogenesis in the sea urchin Lytechinus variegatus

EvoDevo, 2019
Background The sea urchin is a basal deuterostome that is more closely related to vertebrates than many organisms traditionally used to study neurogenesis.
