Analysis of biogenic amines in probiotic and commercial salamis
(Academic Press Inc Elsevier Science, 2020-12)
Biogenic amines (BAs) are mainly formed through decarboxylation of amino acids in fermented food, such as salami, that can occasionally accumulate high concentrations of these compounds. The BAs contents in food are related ...
Dose- and time-dependent effects of oral octopamine treatments on the sucrose responsiveness in stingless bees (Melipona scutellaris)
(Springer, 2017-02)
Biogenic amines modulate physiological responses and, consequently, the behaviour of animals. Here, we present the first pharmacological approach to evaluate the influence of octopamine (OA) in stingless bees (Apidae, ...
Factors affecting the production of putrescine from agmatine by Lactobacillus hilgardii X1B isolated from wine
(Wiley Blackwell Publishing, Inc, 2008-07)
Aims: To elucidate and characterize the metabolic putrescine synthesis pathway from agmatine by Lactobacillus hilgardii X1B. Methods and Results: The putrescine formation from agmatine by resting cells (the normal physiological ...
Solventless amide synthesis catalyzed by biogenic CaCO3 materials
(American Chemical Society, 2020-08-17)
Biogenic carbonates were studied as catalysts in this work for the direct synthesis of amides under solvent-free conditions. Solids were synthesized by microbial coprecipitation of CaCl2 and Ni salts and Cu and Fe salts. ...
NBAD-hydrolase processing in brain and epidermis of Drosophila melanogaster
(University of Oklahoma, 2011-03)
Drosophila melanogaster genes ebony and tan are responsible for the synthesis and hydrolysis of N-â-alanylderivatives of biogenic amines, such as N-â-alanyldopamine (NBAD) and N-â- alanylhistamine (carcinine). These are ...
Co-option of neurotransmitter signaling for inter-organismal communication in C. elegans
(Nature, 2019-07-18)
Biogenic amine neurotransmitters play a central role in metazoan biology, and both their chemical structures and cognate receptors are evolutionarily conserved. Their primary roles are in cell-to-cell signaling, as biogenic ...
Individual aggressiveness in the crab Chasmagnathus: Influence in fight outcome and modulation by serotonin and octopamine
(Pergamon-Elsevier Science Ltd, 2010-11)
In a previous work we found that size-matched Chasmagnathus crabs establish winner-loser relationships that were stable over successive encounters but no evidence of escalation was revealed through fights. Here, we evaluated ...
A scientific note on the first report of honeybee venom inhibiting Paenibacillus larvae growth
(EDP Sciences, 2014-04)
In the eusocial honeybee, Apis mellifera, worker bees use a stinging apparatus for defense. The sting is upplied with venom by glands localized in the abdomen. Honeybee venom (BV) is composed of at least 18 bioactive ...
Does cognition have a role in plasticity of "innate behavior"? A perspective from Drosophila
(Frontiers Media S.A., 2018-08)
The term innate is usually applied to behaviors commonly characterized as stereotypical reactions to the presence of a specific stimulus. "Innate behaviors", such as escape responses or taxes, are described as inborn, ...
Bio-based thermosetting epoxy foams: mechanical and thermal characterization
(American Chemical Society, 2015-07-06)
Thermosetting epoxy foams were synthesized by replacing the commercial synthetic epoxy resin by a biogenic epoxidized vegetable oil. Foam formulations were developed avoiding the use of amine hardeners, organic volatile ...
