Dual‐Functional Polystyrene‐Based Borate Complexes: Recyclable Alkyl Radical Sources and Photodegradable Absorbents

open access: yesChemistry – A European Journal, EarlyView.
Dual‐functional polystyrene‐based polymers bearing 2,2′‐(pyridine‐2,6‐diyl)diphenol (PDP) moieties form photoexcitable alkyl borate complexes: (i) As recyclable radical sources, they enable Giese‐type additions with facile purification by reprecipitation and demonstrate proof‐of‐concept for polymer recovery (50% PDP regeneration).

Considerations for drug trials in hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Inherited metabolic epilepsies–established diseases, new approaches

open access: yesEpilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Therapeutic‐dose verapamil‐induced cardiogenic shock in an older patient: a case report

open access: yesJournal of Pharmacy Practice and Research, EarlyView.
Abstract Background Calcium channel blocker (CCB) toxicity most commonly follows deliberate overdose. However, severe toxicity at therapeutic doses may occur in susceptible individuals. Severe CCB toxicity often presents with clinical features of bradycardia, hypotension, hyperglycaemia, and lactic acidosis.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...
