Potential of Cocoa Ethanol Extract Toward Nematocyst Tubul Firing Inhibition of Physalia Utriculus Toxin In Vitro

open access: yesJournal of Agromedicine and Medical Sciences (AMS), 2019
There was estimated 150 million envenomation cases due to jellyfish stings occur globally every year. 100 from 10,000 jellyfish species in the world known to be dangerous, one them is Physalia utriculus.

The role of heterotrophic plasticity in coral response to natural low‐light environments

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Low‐light environments are driving vertical reef compression and favoring depth generalists within coral communities lying on inshore turbid reefs, highlighting an emerging local threat that is affecting fringing reefs on a global scale. Our study provides direct field evidence that the reef coral Galaxea fascicularis exhibits heterotrophic plasticity,

The gastropod-symbiotic sea anemone genus Isosicyonis Carlgren, 1927 (Actiniaria : Actiniidae): a new species from the Weddell Sea (Antarctica) that clarifies the taxonomic position of the genus [PDF]

open access: yes, 2008
A second species of the sea anemone genus Isosicyonis is described and illustrated from 16 specimens collected in the Weddell Sea (Antarctica) on the Polarstern cruises ANT XVII/3, ANT XXI/2 and ANT XXIII/8. Isosicyonis striata n. sp.

The Chemical Composition of Sea Nettle Nematocysts

open access: yesExperimental Biology and Medicine, 1969
Interest in the stinging apparatus of the sea nettle (Chrysaora quinquecirrha) has been stimulated recently because of the economic problem produced by this organism. Resort activity is severely curtailed during the summer season when the nettle is prevalent.

High‐Resolution Longitudinal eDNA Metabarcoding and Morphological Tracking of Planktonic Threats to Salmon Aquaculture

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
In the current study, we present and assess an exhaustive approach to identify the planktonic drivers of farmed Atlantic salmon complex gill disease (CGD) and fish mortality. We explored delayed or “lagged” effects of plankton abundances on gill health and undertook a comparison of environmental DNA (eDNA) metabarcoding and microscopy in their ability ...

Stem cells of Hydra magnipapillata can differentiate into somatic cells and germ line cells [PDF]

open access: yes, 1987
We investigated whether all stem cells of Hydra can differentiate both somatic cells and gametes or if a separate germ line exists in these phylogenetically old organisms.
