Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Elderly Liver Grafts are More Susceptible to Ischemia‐Reperfusion After Prolonged Cold Ischemia than Grafts from Young Donors—An Ex Vivo Liver Machine Perfusion Analysis in Sprague Dawley Rats

Advanced Therapeutics, EarlyView.
This study investigates how donor age and cold ischemia time influence liver perfusion parameters and injury markers. Older livers are more susceptible to longer ischemia times displaying more tissue damage, and higher expression of oxidative stress and apoptosis‐related proteins than livers with shorter ischemia times.

Perbedaan Pengaruh Bahan Irigasi Ekstrak Propolis 8% dan NaOCl 2,5% terhadap Kekerasan Mikrodentin Saluran Akar [PDF]

, 2018
The most commonly used irrigant for root canal preparation is sodium hypochlorite (NaOCl). This solution may affect the dentin micro hardness. Propolis extract as an alternative materials have been used as an irrigant because of their anti-bacterial ...

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

Advanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

DKK3 Initially Preserves Acinar Integrity Through MEK‐Fos Signaling, but Later Switches to an Oncogenic Role in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic cancer, the protein DKK3 is found to play a complex role: it initially slows early tumor growth but later promotes tumor aggressiveness. DKK3 expression evolves during progression and drives cancer severity by orchestrating cellular and molecular signaling pathways.
