Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

Angewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...

Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators

Angewandte Chemie, EarlyView.
Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

Angewandte Chemie, EarlyView.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis

Angewandte Chemie, EarlyView.
Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation

Photosystem II functionality in barley responds dynamically to changes in leaf manganese status

Frontiers in Plant Science, 2016
A catalytic manganese (Mn) cluster is required for the oxidation of water in the oxygen-evolving complex (OEC) of photosystem II (PSII) in plants. Despite this essential role of Mn in generating the electrons driving photosynthesis, limited information ...
