Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Trifluoperazine causes mast cell apoptosis through a secretory granule-mediated pathway

Cell Death Discovery
Mast cells contribute to the pathology of various diseases, in particular allergic conditions. Therefore, it is essential to develop strategies that efficiently prevent their harmful effects under such circumstances.

Molecular pathways underlying amyloid precursor protein–mediated regulation of adult-born neurons

Neural Regeneration Research
Cleavage of amyloid precursor protein (APP) produces toxic amyloid-beta peptides, which play a critical role in the pathogenesis of Alzheimer’s disease. Neuronal loss is a key feature of Alzheimer’s disease.

Fate of Shed Mast Cell Granules.

Experimental Biology and Medicine, 1956
SummaryIt has been observed that following mild trauma to the skin of mice, degranulation of mast cells occurs in the subcutaneous connective tissue and is followed by the appearance of metachromatic granules within the cytoplasm of surrounding fibroblasts. Investigation of this phenomenon by subcutaneous injection of isolated mast cell granules showed

Oppositely Charged Single Enzyme Nanogels Form Versatile Coacervates for Efficient Enzyme Cascade Catalysis

Advanced Materials, EarlyView.
Oppositely charged single enzyme nanogels (SENs) phase‐separate into bi‐enzymatic coacervate microdroplets, acting as both scaffold and functional units. By tuning SEN ratios, these coacervates create specific microenvironments that enable selective small‐molecule enrichment and efficient intermediate diffusion.

Cell-Biological Requirements for the Generation of Dentate Gyrus Granule Neurons

Frontiers in Cellular Neuroscience, 2018
The dentate gyrus (DG) receives highly processed information from the associative cortices functionally integrated in the trisynaptic hippocampal circuit, which contributes to the formation of new episodic memories and the spontaneous exploration of ...

Tissue eosinophilia and eosinophil degranulation in Riedel's invasive fibrous thyroiditis. [PDF]

, 1996
The etiology of Riedel's invasive fibrous thyroiditis (IFT) has remained obscure. This rare disorder has been confused in the past with the more common fibrous variant of Hashimoto's disease.

Denervation-induced homeostatic dendritic plasticity in morphological granule cell models

Frontiers in Systems Neuroscience, 2014
Neuronal death and subsequent denervation of target areas are major consequences of several neurological conditions such asischemia or neurodegeneration (Alzheimer's disease). The denervation-induced axonal loss results in reorganization of the dendritic
