Specialist or generalist? Feeding ecology of the Malagasy poison frog Mantella aurantiaca [PDF]

, 2007
We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey.

Chemical Approaches for Array Based Detection of Amyloids

Advanced Sensor Research, EarlyView.
Amyloids are protein aggregates with both pathological and functional roles. Their detection is challenged by structural polymorphism, isoform diversity, and dynamic aggregation behavior. This review presents chemical array‐based sensing strategies that address these complexities, emphasizing fluorescence and colorimetric methods, alongside ...

Vinburnine Sensitizes Radiotherapy Efficacy in Nasopharyngeal Carcinoma by Triggering Pyroptosis and Immune Responses via Activation of EDAR‐NFκB Pathway

Advanced Science, EarlyView.
This study demonstrates that vinburnine, an approved cerebrovascular drug, synergizes with radiotherapy in nasopharyngeal carcinoma (NPC) by modulating EDAR‐NFκB signaling through directly binding to EDAR, leading to triggering apoptosis/pyroptosis, and amplifying CCL5/CX3CL1‐driven T‐cell cytotoxicity.

Luminescent Nanocucurbits Enable Spatiotemporal Co‐Delivery of Hydrophilic and Hydrophobic Chemotherapeutic Agents

Advanced Science, EarlyView.
A cucurbit‐shaped luminescent nanoparticle (nanocucurbit) is engineered through the self‐assembly of polypeptides conjugated with aggregation‐induced emission (AIE) fluorophore. The resulting nanocucurbit exhibits approximately two‐fold higher cellular internalization efficiency compared to its spherical counterparts.

Enantioselective Synthesis of α‐Arylated Allene Ketones Through Sequential Bismuth(V)‐mediated Arylation and Organocatalytic Protonation

Angewandte Chemie, EarlyView.
We report an asymmetric synthesis of α‐arylated allenones achieved via sequential bismuth(V)‐mediated arylation and organocatalytic protonation. This method furnishes enantioenriched α‐arylated allenones with broad functional‐group tolerance. Mechanistic studies support a cascade sequence involving enolate formation, arly migration, and irreversible ...
