Summary: Three new feruloyl glucuronopyranosyl glycerols were isolated from Eriocaulon buergerianum Koern and identified as potential inhibitors of TGF-beta 1 receptor. Among them, one glycerol (1) exhibited strong inhibitory activity against TGF-beta-induced protein expression in human hepatic stellate LX-2 cells. These findings suggest that the new feruloyl glucuronopyranosyl glycerol 1 has preventive and therapeutic potentials against hepatic fibrosis.

Summary: This study reports the coordination assembly of ferrocene-diphenylalanine (Fc-FF) with divalent copper ions (Cu2+), resulting in the formation of metal-peptide assemblies (MPAs) with hierarchical spiral architectures. The MPAs consist of helically organized nanofibers that resemble logarithmic spirals. These MPAs exhibit hierarchically porous structures with abundant Fc and Cu2+ active sites, displaying significantly higher catalytic activity than natural laccase in decolorization reactions. Furthermore, the temperature and enantiomeric excess (ee) can be controlled to synthesize a series of hierarchical structures for MPAs. Peptide enantiomers with higher ee values self-assemble into highly complex and ordered structures, which exhibit higher surface area and porosity and thus enhanced catalytic activity compared to those assembled by peptides with lower ee values. These findings provide new insights into the crucial role of chirality in directing the self-assembly of biomolecules into highly ordered complex functional structures.

Summary: Scientific papers are crucial for academic communication, but many of them lack in-depth research and present core content ambiguously, hindering the progression of science and technology. To address this challenge, the INTEGrity vERification (INTEGER) task is introduced to help researchers assess the integrity of their papers and verify the clarity of each knowledge unit. A multi-task learning model utilizing Tucker decomposition and span-level attention mechanism is proposed to accurately identify terms and their integrity. Experimental results show the effectiveness of the model.
