A roadmap to the enzymes from spider venom: biochemical ecology, molecular diversity, and value for the bioeconomy

Frontiers in Arachnid Science
Spiders are ancient and highly successful predators, which use venom for both predation and defense. Their venoms are complex mixtures of potent biological molecules, emerging as a prolific source of biomolecular innovation in agriculture, biomedicine ...

The expressiveness of spider diagrams augmented with constants [PDF]

, 2009
Spider diagrams are a visual language for expressing logical statements or constraints. Several sound and complete spider diagram systems have been developed and it has been shown that they are equivalent in expressive power to monadic first order logic ...

On the Completeness of Spider Diagrams Augmented with Constants [PDF]

, 2013
Diagrammatic reasoning can be described formally by a number of diagrammatic logics; spider diagrams are one of these, and are used for expressing logical statements about set membership and containment. Here, existing work on spider diagrams is extended

Electrophysiological evaluation of the effect of peptide toxins on voltage-gated ion channels: a scoping review on theoretical and methodological aspects with focus on the Central and South American experience [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases
The effect of peptide toxins on voltage-gated ion channels can be reliably assessed using electrophysiological assays, such as the patch-clamp technique.

An Economic Dilemma between Molecular Weapon Systems May Explain an Arachno-Atypical Venom in Wasp Spiders (Argiope bruennichi)

Biomolecules, 2020
Spiders use venom to subdue their prey, but little is known about the diversity of venoms in different spider families. Given the limited data available for orb-weaver spiders (Araneidae), we selected the wasp spider Argiope bruennichi for detailed ...

Functional and Proteomic Insights into Aculeata Venoms

, 2023
Aculeate hymenopterans use their venom for a variety of different purposes. The venom of solitary aculeates paralyze and preserve prey without killing it, whereas social aculeates utilize their venom in defence of their colony.

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

The Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Neuroactive venom compounds obtained from Phlogiellus bundokalbo as potential leads for neurodegenerative diseases: insights on their acetylcholinesterase and beta-secretase inhibitory activities in vitro

Journal of Venomous Animals and Toxins including Tropical Diseases, 2021
Background Spider venom is a rich cocktail of neuroactive compounds designed to prey capture and defense against predators that act on neuronal membrane proteins, in particular, acetylcholinesterases (AChE) that regulate synaptic transmission through ...

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

Symbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.
