Seabather's eruption: report of case in northeast region of Brazil Prurido do traje do banho: relato de caso na região nordeste do Brasil

Anais Brasileiros de Dermatologia, 2012
Seabather's eruption is characterized by the occurrence of intensely itchy erythematous papules observed mainly in the region covered by swimwear. The dermatitis occurs due to the contact of planula larvae of scyphomedusae Linuche unguiculata with the ...

POTENTIAL USEFULNESS OF PLANT EXTRACTS TO COUNTERACT CNIDARIAN VENOMS

, 2021
Cnidarians toxins are known to have a high impact on public health in marine coastal zones the world over. Consequently these toxins are now recognised as an important focus for research on their therapeutic potential. To date several therapeutically important activities have been experimentally identified in cnidarian extracts and venoms. However, the

The property of larval cells of the scleractinian coral, Acropora tenuis, deduced from in vitro cultured cells

Development, Growth &Differentiation, Volume 67, Issue 3, Page 119-135, April 2025.
Using antibodies raised against in vitro cultured cells, we determined the property of coral larval cells. Neuronal cells, ectoderm cells, and endoderm cells were characterized. Abstract In previous studies, we have established approximately 15 cultured cell‐lines derived from planula larvae of Acropora tenuis.

A Morphospace Exploration Using a General Model of Development Reveals a Basic Set of Morphologies for Early Animal Development and Evolution

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 45-58, March 2025.
This work used the model EmbryoMaker to explore the most basic set of morphologies that can be produced from spherical initial conditions by activating cell properties and behaviors in simple genetic territories. We found five possible morphogenetic transformations: invagination, evagination, elongation, condensation and anisotropic growth.

Origin and evolution of microvilli

Biology of the Cell, Volume 116, Issue 11, November 2024.
Microvilli are widespread organelles of animal cells that frequently play a role in sensation and feeding. Ansel et al. reconstitute their origin and evolution by performing a broad morphological survey of microvilli in animals and their unicellular relatives, coupled with a bioinformatic study of the phylogenetic distribution of the main microvillar ...

eDNA Is a Useful Environmental Monitoring Tool for Assessing Stream Ecological Health

Environmental DNA, Volume 6, Issue 4, July–August 2024.
Ecosystem health assessments made by traditional biomonitoring techniques were compared to those made using eDNA at 53 sites throughout New Zealand. We found a high degree of correlation and convergence between biotic indices calculated from traditional biomonitoring techniques and from eDNA.

Characteristics of hemolytic activity induced by the aqueous extract of the Mexican fire coral Millepora complanata

Journal of Venomous Animals and Toxins including Tropical Diseases, 2014
BackgroundMillepora complanata is a plate-like fire coral common throughout the Caribbean. Contact with this species usually provokes burning pain, erythema and urticariform lesions. Our previous study suggested that the aqueous extract of M.

A sedimentary DNA record of the Atacama Trench reveals biodiversity changes in the most productive marine ecosystem

Global Change Biology, Volume 30, Issue 7, July 2024.
Using DNA deposited in deep‐sea sediments, we examine how marine biodiversity has changed over the last 150 years in Chilean waters. We find a unique period aligning with high fishing and extreme climatic events that reduces overall diversity. Furthermore, we find an effect of sea surface temperature and El Nino events over diversity, providing an idea

Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. Most of these studied extracts were obtained from sea anemones or jellyfish.
