Direct Observation of a Hydrogen‐Bonding Assisted Quasi‐Reversible Superoxo/Peroxo Interconversion in a Heme Model

open access: yesChemistry – A European Journal, EarlyView.
First direct observation of a quasi‐reversible superoxo (FeIII─O2˙ˉ)/peroxo (FeIII─O22ˉ) redox couple in a heme model complex, featuring a biologically relevant low‐spin ferric end‐on peroxo species stabilized by second‐sphere hydrogen bonding. These findings highlight the key role of second‐sphere interactions in modulating O2 activation pathways ...

Azoimidazolium Salts as a Platform for Persistent Neutral Aminyl Radicals and Mesoionic Carbene Au(I) Complexes as Cell‐Permeable Fluorophores

open access: yesChemistry – A European Journal, EarlyView.
Strategic electronic matching between imidazolium salts and aryldiazonium salts enables a chromatography‐free route to versatile azoimidazolium scaffolds. Fine‐tuning the substituents unveils a powerful dichotomy: strong ─OMe resonance stabilizes highly persistent neutral aminyl radicals (up to 3 weeks), whereas the superior ─NMe2 donor strength yields

Assessing ZIF‐8 Stability for Biomedical Applications Using Fluorescent Probes: Impact of Covalent Conjugation

open access: yesChemistry – A European Journal, EarlyView.
Using fluorescein as a probe, we compare PEG (polyethylene glycol) surface coatings of ZIF‐8 (zeolitic imidazolate framework‐8) based on coordinative versus covalent attachment and show that PEG coatings provide only limited protection in phosphate‐buffered saline.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Triglyceride Polygenic Score Identifies Individuals Who May Respond Differently to Aspirin in Primary Prevention

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Low‐dose aspirin is no longer routinely recommended for the primary prevention of cardiovascular disease in older adults due to a lack of net benefit over bleeding risk. We hypothesized that genetic subgroups may experience differential harm or benefit from aspirin therapy.

A Pilot Randomized Study of NAT2 and YEATS4 Pharmacogenetic Return of Results in Adults with Hypertension and African Ancestry: The GUARDD‐US PGx Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Almost half of individuals with hypertension fail to achieve recommended blood pressure (BP) goals. Pharmacogenetic gene‐drug interactions may alter the efficacy of antihypertensive agents. We conducted a multicenter randomized controlled sub‐study of participants (N = 1874) with hypertension and self‐reported African ancestry to determine whether ...
