Comparisons of Protein and Peptide Complexity in Poneroid and Formicoid Ant Venoms [PDF]
Journal of Proteome Research, 2016 © 2016 American Chemical Society. Animal venom peptides are currently being developed as novel drugs and bioinsecticides. Because ants use venoms for defense and predation, venomous ants represent an untapped source of potential bioactive toxins.

Diversity of peptide toxins from stinging ant venoms
Toxicon, 2014 Ants (Hymenoptera: Formicidae) represent a taxonomically diverse group of arthropods comprising nearly 13,000 extant species. Sixteen ant subfamilies have individuals that possess a stinger and use their venom for purposes such as a defence against predators, competitors and microbial pathogens, for predation, as well as for social communication.

Fire ant venoms: Chemotaxonomic correlations with alkaloidal compositions
Toxicon, 1976 Abstract The venom alkaloid compositions of workers from 29 populations of about 13 New World fire ant species (genus Solenopsis) have been investigated in an attempt to correlate this potential character with the current views of the taxonomy of this genus.

Using time-resolved fluorescence to measure serum venom-specific IgE and IgG. [PDF]
PLoS ONE, 2011 We adapted DELFIA™ (dissociation-enhanced lanthanide fluoroimmunoassay), a time resolved fluorescence method, to quantitate whole venom specific and allergenic peptide-specific IgE (sIgE), sIgG(1) and sIgG(4) in serum from people clinically allergic to ...

Local Field Potential‐Based Programming: A Proof‐of‐Concept Pilot Study
Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives Programming deep brain stimulation (DBS) is still based on a trial‐and‐error approach, often becoming a time‐consuming process for both treating physicians and patients. Several strategies have been proposed to streamline DBS programming, most of which are preliminary and mainly address Parkinson's disease, a condition readily ...

Anaphylaxis caused by stings from the Solenopsis invicta, lava-pés ant or red imported fi re ant [PDF]
Anais Brasileiros de Dermatologia, 2015 Ants are social insects with species of medical interest, such as the fi re ants (Solenopsis sp.). The sting causes inflammation, vesicles and sterile pustules, which may cause allergic phenomena and even anaphylactic shock.
