Venom Function of a New Species of Megalomyrmex Forel, 1885 (Hymenoptera: Formicidae)
Toxins, 2020 Alkaloids are important metabolites found across a variety of organisms with diverse ecological functions. Of particular interest are alkaloids found in ants, organisms well known for dominating the ecosystems they dwell in.

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 ...

A new family of diverse skin peptides from the microhylid frog genus phrynomantis [PDF]
, 2020 A wide range of frogs produce skin poisons composed of bioactive peptides for defence against pathogens, parasites and predators. While several frog families have been thoroughly screened for skin-secreted peptides, others, like the Microhylidae, have ...

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 ...

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]
, 2013 Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Pretender punishment induced by chemical signalling in a queenless ant [PDF]
, 2002 Animal societies are stages for both conflict and cooperation. Reproduction is often monopolized by one or a few individuals who behave aggressively to prevent subordinates from reproducing (for example, naked mole-rats, wasps and ants).

The genomes of two key bumblebee species with primitive eusocial organization [PDF]
, 2015 Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.
