Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

Advanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

EXPERIMENTAL INVESTIGTION OF THE FRETTING PHENOMENON-DEPENDENCE OF NUMBERS CYCLES [PDF]

Fiabilitate şi Durabilitate
Fretting is now fully identified as a small amplitude oscilatory motion which induces a harmonic tangential force between two surfaces in contact.It is related to three main loadings, i.e. fretting-wear, fretting-fatigue and fretting corrosion.Fretting

Fiabilitate şi Durabilitate, 2012
Fretting is now fully identified as a small amplitude oscillatory motion which induces aharmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e.fretting-wear, fretting-fatigue and fretting corrosion.

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Is the wear coefficient dependent upon slip amplitude in fretting? Vingsbo and Söderberg revisited

, 2015
More than 25 years ago, Vingsbo and Soderberg published a seminal paper regarding the mapping of behaviour in fretting contacts (O. Vingsbo, S. Soderberg, On fretting maps, Wear, 126 (1988) 131–147).

SDS‐CRISPR for Single‐Nucleotide Variant Detection

Advanced Science, EarlyView.
Structure‐disruption‐sensitive CRISPR (SDS‐CRISPR) converts structural instability into single‐nucleotide precision, thereby overcoming mismatch tolerance in canonical Cas12a and enabling versatile diagnostics across DNA, RNA, and microRNA targets. When applied to rapid IDH1 mutation detection for glioma genotyping and integrated with lateral‐flow ...

BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

Angewandte Chemie, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.

The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

Advanced Science, EarlyView.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

Angewandte Chemie, EarlyView.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.
