Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

Chemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...

Synthesis and Photophysical Properties of Star‐Shaped Triphenylamine Trimers Functionalized With BODIPY and Subphthalocyanine Chromophores

Chemistry – A European Journal, EarlyView.
This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation

ESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.
Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

Visible‐Light‐Mediated Synthesis of Biscoumarins Utilizing Photocaged Sulfonic Acid as the Catalyst

European Journal of Organic Chemistry, EarlyView.
A mild visible light approach for the synthesis of biscoumarins utilizing arylazo sulfones as the photoacid generator under 467 nm irradiation is introduced. Throughout the years, biscoumarin derivatives, known for their diverse biological properties, have attracted extensive synthetic interest.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Coumarin necrosis.

, 1980
Necrosis of the skin developed soon after the initiation of coumarin therapy in an elderly woman. Inadvertent rechallenge resulted in similar lesions. Coumarin necrosis is a poorly understood phenomenon unlikely to respond to therapy.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Mango Seed Valorization: Sustainable Source of Nutrients, Bioactives, and Value‐Added Applications

Food Chemistry International, EarlyView.
Highlighting mango seed as a valuable yet overlooked by‐product, promoting its utilization and reducing agroindustrial waste. ABSTRACT Mango (Mangifera indica L.) is one of the most widely cultivated tropical fruits, generating large quantities of by‐products during processing, with mango seed representing 20%–25% of the whole fruit weight ...

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.
