Advanced Science, EarlyView.The C3‐symmetric conjugate TASe, which integrates benzoselenadiazole, alanine, and acylhydrazone modules, self‐assembles into a chalcogen‐/hydrogen‐bonded porous framework in the solid state and uniform chiral nanospheres in aqueous media. These assemblies protect cardiomyocytes from doxorubicin‐induced oxidative injury by scavenging intracellular ...

SN 2021dbg: A Luminous Type IIP–IIL Supernova Exploding from a Massive Star with a Layered Shell
The Astrophysical JournalWe present extensive observations and analysis of supernova (SN) SN 2021dbg, utilizing optical photometry and spectroscopy. For approximately 385 days following the explosion, SN 2021dbg exhibited remarkable luminosity, surpassing most Type II SNe (SNe ...

Progenitors and Hydrodynamics of Type II and lb Supernovae [PDF]
International Astronomical Union Colloquium, 1996 We review critical physics affecting the observational characteristics of those supernovae that occur in massive stars. Particular emphasis is given to 1) how mass loss, either to a binary companion or by a radiatively driven wind, affects the type and light curve of the supernova, and 2) the interaction of the outgoing supernova shock with regions of ...

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome
Annals of Neurology, EarlyView.Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.

European Journal of Organic Chemistry, EarlyView.An efficient gold‐catalyzed intramolecular cyclization of indole‐tethered alkynes using AgNTf2 as an additive has been developed, which provides bioactive exocyclic alkenyl tetrahydrocarbazoles with up to 85% yield. Control experiments and DFT studies indicate that the reaction proceeds via a 6‐exo‐dig cyclization pathway, with gold acetylide complexes

Journal of Applied Toxicology, EarlyView.ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...
