Inhomogeneous Mode-Coupling Theory and Growing Dynamic Length in Supercooled Liquids

open access: yes, 2006
We extend Mode-Coupling Theory (MCT) to inhomogeneous situations, relevant for supercooled liquid in pores, close to a surface, or in an external field.

Ketogenic Diet as an Epigenetic Therapy in SETD1B‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Histone lysine methyltransferases such as SETD1B regulate chromatin structure and gene transcription. Ketone bodies, including butyrate, act as histone deacetylase inhibitors. We report a 4‐year‐old boy with SETD1B‐related absence epilepsy, refractory to conventional medications, who achieved sustained > 90% seizure reduction on the Modified ...

中链甘油三酯对阿尔茨海默病影响的研究进展Progress in the impact of medium-chain triglyceride in Alzheimer′s disease

open access: yesZhongguo youzhi, 2023
为了研究中链甘油三酯(MCT)对延缓阿尔茨海默病(AD)发生的有效性,分析了MCT在体内的代谢过程,综述了MCT对AD的作用机制,介绍了MCT食品针对AD的应用状况。MCT可能通过抗氧化作用、抗炎作用、减少脑淀粉样蛋白-β沉积、保护线粒体功能以及改善脑能量代谢等方面延缓AD的发生。目前已有基于MCT的食品用于缓解AD患者的病情,如Axona(由MCT组成)、Ketonformula(基于MCT配方的奶粉)等。MCT对AD有一定的改善作用,在日常饮食中合理运用MCT可以延缓AD发生。In order ...

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Crossover from $\beta$- to $\alpha$-relaxation in cooperative facilitation dynamics

open access: yes, 2015
$\beta$ and $\alpha$ relaxation processes are dynamical scaling regimes of glassy systems occurring on two separate time scales which both diverge as the glass state is approached. We study here the crossover scaling from $\beta$- to $\alpha$- relaxation

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,
