The Chemistry and Biology of the Tetrodotoxin Natural Product Family

Angewandte 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.

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

BMEMat, 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

Spatial Distribution and Biochemical Characterization of Serine Peptidase Inhibitors in the Venom of the Brazilian Sea Anemone Anthopleura cascaia Using Mass Spectrometry Imaging

Marine Drugs, 2023
Sea anemones are known to produce a diverse array of toxins with different cysteine-rich peptide scaffolds in their venoms. The serine peptidase inhibitors, specifically Kunitz inhibitors, are an important toxin family that is believed to function as ...

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

Ecography, 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

Journal 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 ...

Antifouling Coatings Inspired by Biological Templates

Macromolecular Rapid Communications, EarlyView.
The polymeric coatings developed using biological templates combine antifouling properties of polymers with mechanical properties of micro‐ and nano‐particles yielding contact active, foulant releasable, and stimuli responsive materials with superior antifouling performance and demonstrate several applications in the marine environment, as delivery ...

The birth and death of toxins with distinct functions: a case study in the sea anemone Nematostella.

Molecular biology and evolution, 2019
The cnidarian Nematostella vectensis has become an established lab model, providing unique opportunities for venom evolution research. The Nematostella venom system is multimodal: involving both nematocytes and ectodermal gland cells, which produce a ...

Structural complexity of hard substrates shapes shallow marine benthic communities

Oikos, EarlyView.
Structurally complex habitats offer niche diversity, with varying biotic and abiotic conditions, generally leading to higher biodiversity compared to simpler habitats. However, our understanding of the response of ecological communities to increased complexity and the underlying drivers remain ambiguous due to discrepancies in how complexity is ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

The rise of the starlet sea anemone Nematostella vectensis as a model system to investigate development and regeneration

Wiley Interdisciplinary Reviews: Developmental Biology, 2016
Reverse genetics and next‐generation sequencing unlocked a new era in biology. It is now possible to identify an animal(s) with the unique biology most relevant to a particular question and rapidly generate tools to functionally dissect that biology ...
