The Evolutionary Origin of the Runx/CBFbeta Transcription Factors – Studies of the Most Basal Metazoans [PDF]

open access: yes, 2008
BACKGROUND. Members of the Runx family of transcriptional regulators, which bind DNA as heterodimers with CBFβ, are known to play critical roles in embryonic development in many triploblastic animals such as mammals and insects.

Worldwide exploration of the microbiome harbored by the cnidarian model, Exaiptasia pallida (Agassiz in Verrill, 1864) indicates a lack of bacterial association specificity at a lower taxonomic rank [PDF]

open access: yesPeerJ, 2017
Examination of host-microbe interactions in early diverging metazoans, such as cnidarians, is of great interest from an evolutionary perspective to understand how host-microbial consortia have evolved.

The sea anemone Bunodactis octoradiata (Anthozoa: Actiniaria) from southern Patagonia: morphological study and new records [PDF]

open access: yes, 2014
Bunodactis Verril, 1899 comprises at present 19 nominal species of sea anemones. The validity of the genus is under discussion. The description of the species, Bunodactis octoradiata Carlgren, 1899, is insufficient for reliable identification, and ...

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Effect of Crude Extract from the Sea Anemone Bunodeopsis globulifera on Voltage-Gated Ion Channels from Central and Peripheral Murine Nervous Systems

open access: yesPharmaceuticals
Sea anemones are an important source of bioactive compounds with potential pharmacological applications. Their toxins are produced and stored in organelles called nematocysts and act on specific targets, including voltage-gated ion channels. To date, sea

Neural electrodes for brain‐computer interface system: From rigid to soft

open access: yesBMEMat, EarlyView.
Here, we review the development trends of neural electrodes in BCI. This paper highlights the critical role of electrodes in BCI systems, analyzes the limitations of rigid electrodes, and introduces various flexible electrodes. Furthermore, we discuss application scenarios and prospects of BCI electrode technology, aiming to provide valuable references

Three species of intertidal sea anemones (Anthozoa: Actiniidae) from the Tropical Pacific : Description of anthopleura buddemeieri, n. sp., with remarks on anthopleura asiatica and gyractis sesere [PDF]

open access: yes, 2005
A new species of sea anemone, Anthopleura buddemeieri Fautin, is described from Fiji and Papua New Guinea. Occurring high in the intertidal zone, a typical individual has a column rich brown in color and marked with longitudinal rows of red spots ...

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
