Retos en el estudio de membranas biológicas usando simulaciones de dinámica molecular

Epistemus
En el estudio de simulaciones de membrana modelo, la selección de componentes resulta crucial. Incluso al considerar solo la bicapa, núcleo esencial de la membrana, distintos lípidos generan variadas interacciones, influyendo en el comportamiento del ...

Correlazioni spazio-temporali tra dinamica veloce e rilassamento in liquidi sottoraffreddati e polimeri [PDF]

L'esistenza di una correlazione tra dinamica vibrazionale e rilassamento strutturale in liquidi sottoraffreddati e polimeri è stata confermata di recente.

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, Volume 143, Issue 14, April 10, 2026.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

USO DA RMN DE BAIXA RESOLUÇÃO NA AVALIAÇÃO DA DINÂMICA MOLECULAR DO Origanum vulgare

Química Nova, 2015
In this work, proton NMR relaxometry was used to measure the behavior of spin-lattice relaxation time with T1H as the time constant, and also of spin-spin relaxation time with the time constant T2H.

Coulomb and spin-orbit interactions in random phase approximation calculations

, 2013
We present a fully self-consistent computational framework composed by Hartree-Fock plus ran- dom phase approximation where the spin-orbit and Coulomb terms of the interaction are included in both steps of the calculations.

Targeting Glutamate Excitotoxicity With Memantine Modulates Glial Response and Protects Motoneurons After Spinal Root Lesion

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Motoneuron axotomy induced marked neuroinflammation, synaptic withdrawal, and structural remodeling in the ventral root crush (VRC) model, characterized by intense microglial and astroglial activation and reduced synaptic coverage. Memantine treatment produced consistent, dose‐dependent neuroprotection, with maximal effects at 45 mg/kg.
