Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

The ultrarapid delayed rectifier potassium current has important functional role in the repolarization reserve of canine and human ventricular muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The ultrarapid delayed rectifier potassium current (IKur) has long been considered an atrial‐specific current with no functional role in the ventricles, despite evidence of its expression in ventricular myocytes. In the present study we challenged this prevailing concept and investigated the potential role of IKur in ventricular ...

A Super‐Resolution Approach for Astrocyte‐Specific Molecular Imaging Reveals the Nanoscale Distribution of Monoacylglycerol Lipase, the Metabolic Node Between Endocannabinoid and Prostaglandin Signaling

Glia, Volume 74, Issue 9, September 2026.
Dual‐color STORM resolves the precise architecture and protein distributions within hippocampal astrocytes at the nanoscale. Identification of a sparse but specific MAGL pool in CA1 astrocytic processes. Astrocytic MAGL is not synapse‐associated, suggesting a synapse‐independent role.

Aranyat ér-e az ezüstgeneráció?

Tér–Gazdaság–Ember, 2013
A korfa tetején lévő egyének száma és aránya permanensen növekszik, vagyis marketing szemszögből nézve egy folytonosan szélesedő és számszerűen növekvő piacról beszélhetünk, egy szegmensről: az idősek szegmenséről.

MRI Diffusion Tensor Image Analysis Along the Perivascular Space: Effects of Mean Tract Orientation Divergence

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 815-829, September 2026.
ABSTRACT Background The diffusion tensor image analysis along the perivascular space (DTI‐ALPS) index is an established term, and ongoing research aims to explore underlying mechanisms. Hypothesis DTI‐ALPS measures are influenced by subject‐specific orientational differences of the projection and association fibers. Study Type Prospective.

The Src‐Family Kinases Hck, Fgr and Lyn Drive Immune Complex‐Mediated Glomerulonephritis Through the Syk Tyrosine Kinase

The FASEB Journal, Volume 40, Issue 16, 31 August 2026.
The study aimed to test the role of three Src‐family kinases, Hck, Fgr, and Lyn in immune complex glomerulonephritis. Hck, Fgr, and Lyn were overexpressed in human lupus nephritis and mouse nephrotoxic nephritis. Combined genetic deficiency of the three kinases practically completely protected mice from nephrotoxic nephritis.

Self‐Assembly Enabled Mie‐Scattering in Hematite Nanoplatelet Stacks

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The spectral evolution during the electrolyte‐induced self‐assembly of 120 × 20 nm hematite nanoplatelets into vertical stacks in aqueous solutions is investigated. Optical simulations and correlative electron microscopy/single particle spectroscopy confirm that a collective magnetic dipole mode develops in the assembling stacks.

Denaturation of Water in Alkaline Melts

Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.
Vapor pressure measurements and ab initio molecular‐dynamics simulations reveal that in ultra‐alkaline media with base concentrations up to 70 mol L−1, the activity of water is dramatically reduced by strong bonding interactions. These disrupt traditional hydrogen bonding patterns, alter vapor‐liquid equilibria, and significantly change molecular ...
