CRP Deficiency Rescues Periodontitis‐Induced Hippocampal Neurogenesis Impairment by Suppressing OPC‐Derived BMP4 Signaling in Rats

Advanced Science, EarlyView.
Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Are the firm owners really worse off with a works council? [PDF]

As they are employee associations, it is typically presumed that works councils redistribute economic rents from firm owners to workers. And indeed, empirical literature suggests that works councils reduce profits although, at the same time, they ...

Cryo‐EM Structure Guided Engineering of Botulinum Neurotoxin A With Advanced Receptor Binding Affinity and Therapeutical Benefits

Advanced Science, EarlyView.
The butterfly unfolded wing in an open form structure of botulinum neurotoxin type A (BoNT/A) at physiological‐state was confirmed at 2.85 Å resolution by cryo‐electron microscopy (cryo‐EM). Structure‐guided protein engineering significantly enhanced the receptor‐binding affinity, therapeutic efficacy, and safety of the engineered toxin variants ...

Test study on the effect of lubricants on E-axle power loss

Jixie chuandong
ObjectiveThe typical input speed of the electric drive axle is 12 000-22 000 r/min, but the existing research work basically focuses on the gearbox, drive axle and other gear transmission devices used in traditional internal combustion engines.

Self‐Assembling Hybrid Hydrogel Reprograms the Stromal Vascular Fraction to Treat Osteoarthritis

Advanced Science, EarlyView.
This study presents a bioinspired injectable hydrogel that enhances the therapeutic potential of stem cell‐rich stromal vascular fraction for treating osteoarthritis. By reprogramming cell behavior through epigenetic modulation, the hydrogel promotes cartilage regeneration and reduces joint damage in a rat model, offering a promising new approach for ...
