The Effect of Acute Beetroot Juice and Caffeine Supplementation on Specific Judo Performance During a Simulated Competition Day in Judo Athletes

European Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT Beetroot juice (BJ) and caffeine (CAF) are well‐established ergogenic aids for exercise performance. However, little is known about their efficacy and interaction within the specific context of a judo competition day. This study investigated the acute effects of BJ, CAF, and their combination (BJCAF) on judo‐specific performance across a ...

Polymorphs of Theophylline Characterized by DNP Enhanced Solid-State NMR

Molecular Pharmaceutics, 2015
We show how dynamic nuclear polarization (DNP) enhanced solid-state NMR spectroscopy can be used to characterize polymorphs and solvates of organic solids. We applied DNP to three polymorphs and one hydrated form of the asthma drug molecule theophylline.

Tuning the Triazolotriazine Scaffold Toward Selective A3 Adenosine Receptor Antagonists: From Molecular Recognition to Neuroprotection

ChemMedChem, Volume 21, Issue 20, 28 October 2026.
Structure‐based optimization of the triazolo‐triazine scaffold afforded highly potent and selective adenosine A3 receptor antagonists. Replacement of the classical 2‐furyl group with phenyl‐based substituents markedly improved A3 receptor affinity and selectivity.

From Caffeine to Aspirin: Everyday Molecules as Triggers for Genetically Encoded Proximity Systems

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
This Perspective article highlights how familiar dietary ingredients and over‐the‐counter (OTC) drugs (such as caffeine and its metabolites, SA, and aspirin) can be repurposed as clinically translatable chemical triggers for genetically encoded proximity systems.

Detection Range Setting via Electropolymerization of Molecularly Imprinted Polymers With Plasmonic Optical Fiber Probes – The Case Study of Caffeine as a Small Molecule

Advanced Sensor Research, Volume 5, Issue 10, October 2026.
The capabilities of surface plasmon resonance optical fiber probes combined with electropolymerized molecularly imprinted polymers (eMIPs) are used to extend the small‐size molecule detection concentration range by tuning eMIP layer thicknesses. This tuning is achieved by modifying a single electropolymerization parameter: the deposition time.
