Drought affects Fe deficiency‐induced responses in a purple durum wheat (Triticum turgidum subsp. durum) genotype

open access: yesPlant Biology, EarlyView.
Combined Fe deficiency and drought in durum wheat trigger interactive responses: drought suppressed root Fe uptake regardless of Fe availability, and both stresses altered phytosiderophore release, ABA level and Fe transporter gene expression, revealing a trade‐off between water and Fe. Abstract Iron (Fe) is essential for plants and humans, with over 2

Oxidative stress and impaired cardiovagal baroreflex sensitivity in young adults with post‐traumatic stress disorder

open access: yesExperimental Physiology, EarlyView.
Abstract Post‐traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, yet the underlying physiological characterization in young adults remain unclear. This study examines whether autonomic and/or vascular dysfunction predominates as an early precursor to CVD development in young adults with PTSD and explores the

Experimental and Computational Elucidation of Protic Redox Reaction Mechanisms

open access: yesChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Comparing quantum chemical calculations of redox potentials against experimental data provides a powerful and cost‐effective method for validating proposed protic redox reaction mechanisms, provided that computational and experimental uncertainties are robustly quantified. Molecular design of redox‐active species for applications such as redox sensing,

Regulation of Endoplasmic Reticulum Stress Suppresses Early Pro‐Tumorigenic Events During N‐Nitrosodiethylamine‐Induced Hepatocarcinogenesis

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
Schematic illustration of the effect of BIX in attenuating the initiation stage of hepatocarcinogenesis. BIX pre‐treatment mitigated N‐nitrosodiethylamine‐induced ER stress, DNA damage, and downstream pro‐tumorigenic events during the initiation phase. It preserved DNA repair capacity, reduced inflammation and cellular proliferation, thereby inhibiting

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Synthesis of 2‐Aza‐Bicyclo[4.3.0]nonane Derivatives Related to the Camporidines via Intramolecular [3+2]‐Cycloaddition

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.
