Reinforcement learning with a network of spiking agents [PDF]

open access: yesarXiv, 2019
Neuroscientific theory suggests that dopaminergic neurons broadcast global reward prediction errors to large areas of the brain influencing the synaptic plasticity of the neurons in those regions. We build on this theory to propose a multi-agent learning framework with spiking neurons in the generalized linear model (GLM) formulation as agents, to ...

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Discrimination vs. Generation: The Machine Learning Dichotomy for Dopaminergic Hit Discovery [PDF]

open access: yesarXiv
Virtual screening plays a pivotal role in early drug discovery, traditionally dominated by physics-based methods. While these approaches offer detailed insights, they are often hindered by high computational costs, limited sampling, and forcefield inaccuracies.

Probing the Inhibitory Potential of Halogenated Symmetrical Formamidine Against MAO‐A and MAO‐B: Structural Elucidation, Molecular Dynamic Simulation and DFT Computational Studies

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...

miR-34b/c Regulates Wnt1 and Enhances Mesencephalic Dopaminergic Neuron Differentiation

open access: yesStem Cell Reports, 2018
Summary: The differentiation of dopaminergic neurons requires concerted action of morphogens and transcription factors acting in a precise and well-defined time window. Very little is known about the potential role of microRNA in these events.

Galactose‐Functionalized Gold Nanoparticles Targeting Membrane Transporters for the Glutathione Delivery to Brain Cancer Cells

open access: yesChemBioChem, EarlyView.
Glutathione‐functionalized gold nanoparticles are shown to reduce radicals in SH‐SY5Y and C6 cells. Conjugation of galactose to the outer shell improves internalization through the GLUT transporter, thus providing a smart multivalent system able to reduce oxidative stress in neuroblastoma and rat glioma cells.
