SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

open access: yesAdvanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Twin‐Lever Multifunctional Meta‐Optics With High Longitudinal Tolerance

open access: yesAdvanced Science, EarlyView.
We introduce a single‐layer, CMOS‐compatible metasurface that allows for polarization‐programmable, achromatic broadband dual‐mode imaging with high longitudinal tolerance. The twin‐lever design combines bright‐field focusing and vortex‐based edge‐enhanced imaging while managing axial intensity distribution from 488 to 633 nm.

Protection Motivation Theory and Farmers' Participation in Futures Markets: Evidence From Germany

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines why German farmers show limited adoption of commodity futures contracts despite substantial price volatility, applying Protection Motivation Theory (PMT) to understand the cognitive processes driving participation decisions in futures markets. Survey data from 303 German farmers collected in 2024 were analyzed using Partial

3D Liquid Crystal Framework Enclosing Dual Compartments

open access: yesAngewandte Chemie, EarlyView.
A new type of liquid crystal phase is reported, having the conjugated rod‐like molecular cores form a 3D framework of elongated octahedral cages filled alternatively with alkyl and fluoroalkyl pendant chains. The cages are held together by flexible H‐bonding hinges, making them adaptable to thermal expansion and stable in a wide temperature range.

Radical Resection of the Third Portion of the Duodenum for Secondary Aortoduodenal Fistula

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Secondary aortoduodenal fistula most commonly involves the third portion of the duodenum and requires definitive management of both vascular and gastrointestinal components. We demonstrate a step‐by‐step technique for radical duodenal resection and reconstruction performed in structured collaboration with cardiovascular surgeons.
