A biophysical network model reveals the link between deficient inhibitory cognitive control and major neurotransmitter and neural connectivity hypotheses in schizophrenia [PDF]
We address a biophysical network dynamical model to study how the modulation of dopamine (DA) activity and related N-methyl-d-aspartate (NMDA) glutamate receptor activity as well as the emerging Pre-Frontal Cortex (PFC) functional connectivity network (FCN) affect inhibitory cognitive function in schizophrenia in an antisaccade task.

Rational Design of Inner Ear Drug Delivery Systems
Hearing loss is a common disease affecting many people, and inner ear lesions are one of the most important causes. This review focuses on the treatment of inner ear hearing loss by drug delivery systems. It includes the current methods and technologies developed, and it predicts possible directions.

S‐ketamine binds directly to SIRT2, facilitating its interaction with NF‐κB p65. This interaction reduces the acetylation of NF‐κB p65 and inhibits its activation, thereby exerting anti‐inflammatory and antidepressant effects. Created by BioRender.

NMDA-receptor activation but not ion flux is required for amyloid-beta induced synaptic depression. [PDF]
Alzheimer disease is characterized by a gradual decrease of synaptic function and, ultimately, by neuronal loss. There is considerable evidence supporting the involvement of oligomeric amyloid-beta (Aβ) in the etiology of Alzheimer's disease ...

The P6CIT lipopolymer demonstrates superior transfection efficacy in the spinal cord and DRG, as well as enhanced penetration of the pia mater compared to the MC3 ionizable lipid. Intrathecal delivery of P6CIT LPNPs enables effective transfection in the gliocytes in the spinal cord and DRG.

Quantifying constraints determining independent activation on NMDA receptors mediated currents from evoked and spontaneous synaptic transmission at an individual synapse [PDF]
A synapse acts on neural transmission through a chemical process called synapses fusion between pre-synaptic and post-synaptic terminals. Presynaptic terminals release neurotransmitters either in response to action potential or spontaneously independent of presynaptic activity.

Two-trace model for spike-timing-dependent synaptic plasticity [PDF]
We present an effective model for timing-dependent synaptic plasticity (STDP) in terms of two interacting traces, corresponding to the fraction of activated NMDA receptors and the Ca2+ concentration in the dendritic spine of the postsynaptic neuron.

The Molecular Basis of Amino Acids Sensing
Amino acids are essential as protein building blocks and signaling molecules, enabling metabolic regulation. Cells sense amino acid levels to control protein synthesis, maintain homeostasis, and adapt to nutritional changes. This review explores recent advances in amino acid sensing mechanisms across organisms, highlighting their roles in cellular ...
