IL‐4/STAT6‐signaling Influences Local Inflammation and Regeneration Processes During Acute Pancreatitis and Promotes Fibrosis by a Direct Activation of Pancreatic Fibroblasts During Chronic Pancreatitis

Advanced Science, EarlyView.
IL‐4/IL‐13/STAT6 signaling plays a crucial for the suppression of pro‐inflammation during acute pancreatitis and supports acinar cell regeneration but has only minor impact on fibrogenesis during chronic form of the disease. IL‐4/IL‐13 induce the expression of certain collagens directly in pancreatic fibroblasts via STAT6 activation, whereas ...

An experimental study by method of separatory grids of a deformed state of a mandrel opening

RUDN Journal of Engineering Research, 2013
The subject of this research work was the burnishing process of a cylindrical opening of a multicuspid mandrel (push burnishing broach). It was examined by dividing the change in mesh texture of the surface layer of metal fibers in a section of a ...

A Mini‐Spidroin Forms High‐Performance Artificial Spider Silk via Edge‐Cysteine–Locked β‐Sheet Assembly

Advanced Science, EarlyView.
Cysteine‐engineered mini‐spidroins (∼33 kDa) undergo phosphate‐induced liquid–liquid phase separation (LLPS), where disulfide bonds lock partially aligned polyA segments. Subsequent microfluidic spinning promotes directional β‐sheet crystallization, producing fibers with 531 MPa strength and 182 MJ/m3 toughness.

Analysis on Telescoped Coil Defect of Hot Galvanized Strip and Preventing Measures

Teshugang, 2011
According to analysis on telescoped coil produced during coiling process of hot galvanized strip, it is obtained that the unmatched coiling tension and the slip of mandrel in sleeve are main causes to bring about telescoped coil defect.

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

Advanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Catechol Derivative‐Based Bioadhesives: Molecular Design for Precision Medical Adhesion

Advanced Science, EarlyView.
This study utilizes tree‐inspired side‐chain engineering to graft five catechol derivatives onto PVA, systematically revealing how side‐chain length and substituents regulate adhesion and cohesion properties. Among them, the PVA‐CA patch demonstrates superior tissue adhesion, biocompatibility, and promotes regeneration, establishing a programmable ...
