Progesterone monitoring and gestation length in Amazonian manatees (Trichechus inunguis)

Theriogenology Wild
Knowledge of pregnancy length and the physiological parameters during pregnancy is an important tool for pregnancy diagnosis in free-ranging and captive individuals and for the correct husbandry of captive pregnant females. Therefore, this study aimed to

Age-dependent remodelling of ionotropic signalling in cortical astroglia [PDF]

, 2011
Cortical astrocytes express fast ionotropic receptors for glutamate and ATP, although their role in neurone-glia communication remains controversial.

AMPA-ergic regulation of amyloid-β levels in an Alzheimer’s disease mouse model

Molecular Neurodegeneration, 2018
Background Extracellular aggregation of the amyloid-β (Aβ) peptide into toxic multimers is a key event in Alzheimer’s disease (AD) pathogenesis. Aβ aggregation is concentration-dependent, with higher concentrations of Aβ much more likely to form toxic ...

Molecular pharmacology of AMPA receptor trafficking proteins - TARPs - evidence for an association with 5HT(_2c) receptors [PDF]

, 2009
There has been an increasing awareness of the involvement of neurotransmitters other than serotonin in depression, with new antidepressants possessing effects on other receptor types, such as Agomelatine®, an antagonist of 5HT(_2c) receptors that ...

Differential involvement of NMDA, AMPA/kainate, and dopamine receptors in the nucleus accumbens core in the acquisition and performance of pavlovian approach behavior [PDF]

, 2001
Stimuli paired with primary rewards can acquire emotional valence and the ability to elicit automatic, Pavlovian approach responses that have been shown to be mediated by the nucleus accumbens. The present experiment investigated the effects of infusions

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

Advanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...

AMPA Receptor-Mediated Ca2+ Transients in Mouse Olfactory Ensheathing Cells

Frontiers in Cellular Neuroscience, 2019
Ca2+ signaling in glial cells is primarily triggered by metabotropic pathways and the subsequent Ca2+ release from internal Ca2+ stores. However, there is upcoming evidence that various ion channels might also initiate Ca2+ rises in glial cells by Ca2 ...

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.

Potencial de Chlorophytum comosum para la remediación de suelos contaminados con glifosato

Terra Latinoamericana
El glifosato es un herbicida ampliamente utilizado, pero su uso excesivo ha generado preocupaciones por sus posibles efectos negativos en la salud humana y al ambiente debido a su persistencia en el suelo. La fitorremediación es el uso de la capacidad de

Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]

, 2014
In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...
