Spatial Scale Matters: Hydrolysis of Aryl Methyl Ethers over Zeolites.

The local environment of the active site, such as the confinement of hydronium ions within zeolite pores, significantly influences catalytic turnover, similar to enzyme functionality. This study explores these effects in the hydrolysis of guaiacols─lignin-derived compounds─over zeolites in water. In addition to the interesting catechol products, this reaction is advantageous for study due to its bimolecular hydrolysis pathway, which involves a single energy barrier and no intermediates, simplifying kinetic studies and result interpretation.

Higher-order effects and validity of the point-dipole approximation for conjugated extended molecular emitters near plasmonic nanostructures.

Rapid advancements in nanotechnology have allowed for the characterization of single molecules by placing them in the vicinity of nanoplasmonic structures that are known to confine light to sub-molecular scales. In this study, we introduce a theoretical framework that captures higher-order effects, and we explore the limits of the standard description of a molecular emitter as a point-dipole. We particularly focus on the role played by the emitter chain length and electron conjugation.

Our path together: Development of the inclusive parenting goals questionnaire.

Instruments on parenting goals are often outdated and don't consider goals related to capabilities and needs of children with (severe) disabilities. This study aimed to develop an inclusive questionnaire on parenting goals applicable to parents of all children (0-21 years). The iterative development process relied on academic and experiential expertise of parents and professionals; and included consultation of relevant literature, interviews with 6 parents of a child with severe to profound intellectual disabilities, a feedback round with diverse stakeholders, and a pilot study.

Long-Term Results from an Open-Label Extension Study of Atacicept for the Treatment of IgA Nephropathy.

Background: B-cell activating factor (BAFF) and A proliferation-inducing ligand (APRIL) play key roles in the pathogenesis of IgA nephropathy. Atacicept is a novel fully humanized fusion protein, self-administered at home by subcutaneous injection, that binds and inhibits BAFF and APRIL. By inhibiting BAFF and APRIL, atacicept targets the underlying B-cell–mediated pathogenesis driving disease progression.

Alternative Complement Pathway Inhibition with Iptacopan in IgA Nephropathy.

Background: The alternative complement pathway plays a key role in the pathogenesis of IgA nephropathy. Iptacopan specifically binds to factor B and inhibits the alternative pathway.

Methods: In this phase 3, double-blind, randomized, placebo-controlled trial, we enrolled adults with biopsy-confirmed IgA nephropathy and proteinuria (defined as a 24-hour urinary protein-to-creatinine ratio of ≥1 [with protein and creatinine both measured in grams]) despite optimized supportive therapy.
