The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Fluorescence of Sea Anemones [PDF]
Nature, 1927 I NOTICED recently, upon the rocks in Torbay, a number of sea anemones the tentacles of which appeared to fluoresce in sunlight. The effect is limited to the tentacles, for they appear to have a pinkish-brown colour by transmitted light, which changes to vivid green when viewed by light reflected from their surface.

DNA extraction from sea anemone (Cnidaria: Actiniaria) tissues for molecular analyses
Genetics and Molecular Biology, 2000 A specific DNA extraction method for sea anemones is described in which extraction of total DNA from eight species of sea anemones and one species of corallimorpharian was achieved by changing the standard extraction protocols.

Ecography, Volume 2026, Issue 9, September 2026.The Amazon River plume (ARP) functions as a dynamic and porous biogeographic barrier whose permeability to larval dispersal depends on the interplay between species' biological traits and oceanographic processes. Using biophysical modeling combined with a dual analytical framework, namely a multivariate regression tree (MRT) and a generalized additive ...

Nature, 1912 IN 1904 Dr. J. R. Ashworth and I published in the Proceedings of the Royal Society of Edinburgh (vol. xxv., p. 1) observations on aged individuals of Sagartia troglodytes then and still in the possession of Miss Jessie Nelson in Edinburgh. After eight years these anemones are still in excellent health, having been in captivity for considerably more ...

Multigene Family of Pore-Forming Toxins from Sea Anemone Heteractis crispa
Marine Drugs, 2018 Sea anemones produce pore-forming toxins, actinoporins, which are interesting as tools for cytoplasmic membranes study, as well as being potential therapeutic agents for cancer therapy.

Development, Growth &Differentiation, Volume 68, Issue 7, September 2026.In the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...
