The Journal of Physiology, EarlyView.Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.ABSTRACT Rationale Cannabinoids comprise a chemically diverse group of meroterpenoids whose extensive isomerism, variable side‐chain length, and frequent oxidative or rearranged derivatives lead to strongly overlapping yet characteristic MS/MS fragmentation patterns. In untargeted LC–MS/MS datasets, this combination of structural diversity and spectral

Chinese Journal of Chemistry, Volume 44, Issue 13, Page 2160-2166, 1 July 2026.We present a dual copper/photoredox catalytic system that enables the para‐selective C–H functionalization of benzyl alcohols with sulfenamides. This approach facilitates the para‐selective C–H sulfilimination of benzylic oxime carbonates through an orchestrated sequence involving photoinduced decarboxylation/dearomatization of oxime carbonates, copper‐

Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers
Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Clinical Endocrinology, Volume 105, Issue 1, Page 51-59, July 2026.ABSTRACT Context Adult data indicate that hypogonadism is underdiagnosed and undertreated in Prader‐Willi Syndrome (PWS). Objectives We aimed to describe the spectrum of pubertal development, and the diagnosis and treatment of hypogonadism in paediatric/adolescent patients with PWS. Design/Patients A retrospective cohort study of patients with PWS aged
