The two Eu(III) complexes of 1.Eu and 2.Eu, that were formed in situ, were used to bind to yeast RNA and A10 (RNA) in a buffered pH 7 solution. The interaction gave rise to changes in the lanthanide‐centered emission because of direct binding of these complexes, which resulted in aggregation of the RNA, as demonstrated using phase‐contrast and atomic ...

Self‐assembled photocatalyst Ru(Ada‐bpy)(bpy)2⊂HACD targets cancer cells and catalyzes the prodrug to drug upon exposure to visible light, providing spatially and temporally control in cancer cells. This strategy achieves efficient, controllable, and targeted activation of prodrugs within cancer cells, laying the foundation of effectively reducing the ...

A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)
Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots
This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Exploiting Biocatalysis for the Scalable Synthesis of Enantiopure γ‐Hydroxynitrile Building Blocks
Screening a panel of (S)‐and (R)‐selective alcohol dehydrogenases identified several biocatalysts for stereoselectively reducing γ‐ketonitriles into γ‐hydroxynitriles. These processes were optimized, delivering the targets in yields up to 88% with e.e.’s up to 99%. Scalability of the methodology was achieved to produce gram quantities of product, which
