Inhibition of native 5-HT3 receptor-evoked contractions in Guinea pig and mouse ileum by antimalarial drugs [PDF]

open access: yes, 2014
Quinine, Chloroquine and mefloquine are commonly used to treat malaria; however with associated gastrointestinal (GI) side-effects. These drugs act as antagonists at recombinant 5-HT3 receptors and modulate gut peristalsis.

Serotonin and the regulation of mammalian energy balance.

open access: yesFrontiers in Neuroscience, 2013
Maintenance of energy balance requires regulation of the amount and timing of food intake. Decades of experiments utilizing pharmacological and later genetic manipulations have demonstrated the importance of serotonin signaling in this regulation.

Synthesis of Aminocyclopropanes by Redox‐Neutral Aminoalkylation

open access: yesAngewandte Chemie International Edition, EarlyView.
Aminocyclopropane synthesis by hydroaminoalkylation utilizing cheap, readily available starting materials is presented, offering orthogonality to commonly used methods and allowing broad functional‐group tolerance. Solvent‐mediated conditions enable the reaction of a pre‐formed hemiaminal with alkenes and alkynes.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

open access: yesJournal of Applied Polymer Science, EarlyView.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

open access: yesAnimal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Serotonin and psilocybin activate 5-HT1B receptors to suppress cortical signaling through the claustrum

open access: yesNature Communications
Through its widespread reciprocal connections with the cerebral cortex, the claustrum is implicated in sleep and waking cortical network states. Yet, basic knowledge of neuromodulation in this structure is lacking.
