Single‐Step Electrochemical Aptasensor for Melatonin Detection in Unprocessed Plasma

Advanced Science, EarlyView.
Melatonin is a well‐known biomarker with significant potential for clinical use in diagnosing circadian rhythm sleep disorders (CRSDs) and monitoring patients with documented circadian clock disruption. An electrochemical aptamer‐based biosensor (E‐aptasensor), employing an optimized population of melatonin aptamers, has been proposed as a solution for

Serotonin and Coexisting Peptides in Cat and Lamprey Spinal Cord

, 1990
The innervation of the spinal cord by serotonergic fibres and the presence of coexisting peptides in such fibres are compared in the cat, an advanced mammal, and lamprey, a very primitive vertebrate (cyclostome).

Neuromorphic Devices and Computing for Sensing, Memory, and Control

Advanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

5-HT_FAsTR: a versatile, label-free, high-throughput, fluorescence-based microplate assay to quantify serotonin transport and release

Scientific Reports
The neurotransmitter serotonin plays a pivotal role in mood and depression. It also acts as a vasoconstrictor within blood vessels and is the main neurotransmitter in the gastrointestinal system.

Molecular and pharmacological characterization of serotonin 5-HT2α and 5-HT7 receptors in the salivary glands of the blowfly calliphora vicina [PDF]

, 2012
Secretion in blowfly (Calliphora vicina) salivary glands is stimulated by the biogenic amine serotonin (5-hydroxytryptamine, 5-HT), which activates both inositol 1,4,5-trisphosphate (InsP3)/Ca2+ and cyclic adenosine 3′,5′-monophosphate (cAMP) signalling ...

Carbohydrate‐Mediated Cellular Uptake of Boronic Acid Hybrids In Cellulo and Insulin‐Deficient Zebrafish: Live Imaging and Application of Multiphoton FLIM

Advanced Science, EarlyView.
Boronic acid‐based fluorescent hybrids have been used as part of a versatile platform for real‐time metabolic bioimaging across cellular and organismal scales. Including glucose‐responsive imaging in living cells and in an insulin‐deficient vertebrate model, this work opens new opportunities for the development of precision diagnostics, metabolic ...

Serotonin and the gut microbiome: Pathways, functions, and health implications

The Microbe
Serotonin, an evolutionarily conserved molecule produced in the gut, plays a multifaceted role in host physiology. Several organs within the host can directly synthesize serotonin, yet its activity and secretion are intricately linked to the gut ...
