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 ...

Recent Advances in Research on Widow Spider Venoms and Toxins

Toxins, 2015
Widow spiders have received much attention due to the frequently reported human and animal injures caused by them. Elucidation of the molecular composition and action mechanism of the venoms and toxins has vast implications in the treatment of ...

Spider Venoms Potentially Lethal to Humans [PDF]

, 2013
Spiders have one pair of venom glands, and only a few families have reduced them completely (Uloboridae, Holarchaeidae) or modified them to another function (Symphytognathidae or Scytodidae, see Suter and Stratton 2013).

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

Venom-gland transcriptomics and proteomics of the Tibellus oblongus spider

, 2023
   The EST database includes 1733 records, including 1263 nucleotide sequences with ORFs, of these 942 have been identified as toxin-coding. The database of peptide sequences was built on the basis of the transcriptomics results.

Heterophilic antibodies in sera from individuals without loxoscelism cross-react with phospholipase D from the venom of Loxosceles and Sicarius spiders

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Loxoscelism is a severe human envenomation caused by Loxosceles spider venom. To the best of our knowledge, no study has evaluated the presence of antibodies against Loxosceles venom in loxoscelism patients without treatment with antivenom ...

Specific immunotherapy in Albanian patients with anaphylaxis to hymenoptera venoms [PDF]

, 2002
Background: Severe allergic reactions during rush-specific immunotherapy (Rush-SIT) may occur in the treatment of hymenoptera sting allergy. The objective of the present study was to examine the characteristics of allergic reactions during Rush-SIT in a ...

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 ...

Characterisation of protein families in spider digestive fluids and their role in extra-oral digestion

BMC Genomics, 2017
Background Spiders are predaceous arthropods that are capable of subduing and consuming relatively large prey items compared to their own body size. For this purpose, spiders have evolved potent venoms to immobilise prey and digestive fluids that break ...
