A Bio‐Adaptive Janus‐Adhesive Dressing with Dynamic Lubrication Overlayer for Prevention of Postoperative Infection and Adhesion

Advanced Science, EarlyView.
Slippery‐adhesive Janus gel dressing exhibits both stable tissue adhesive and outstanding efficiency in repelling physiological fluids. As a physical barrier, a liquid‐infused surface with a dynamic lubrication overlayer possesses excellent antibiofouling properties, making it highly effective in preventing bacterial infections and postoperative tissue

Prognostic significance of uPA/PAI-1 level, HER2 status, and traditional histologic factors for survival in node-negative breast cancer patients

Radiology and Oncology, 2016
The association of HER2 status with urokinase plasminogen activator (uPA) and plasminogen activator inhibitor 1 (PAI-1) levels raises the question whether uPA/PAI-1 level carries additional clinically relevant prognostic information independently from ...

Injectable and Sprayable Thermoresponsive Hydrogel with Fouling‐Resistance as an Effective Barrier to Prevent Postoperative Cardiac Adhesions

Advanced Science, EarlyView.
Postoperative cardiac adhesions lead to numerous difficulties in reoperation procedures. Here, a thermo‐responsive in situ formed hydrogel is shown to can reliably cover the wounds after a convenient spraying or injection and significantly reduce adhesion formation in primary and recurrent cardiac injury adhesion models.

Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) in breast cancer - correlation with traditional prognostic factors

Radiology and Oncology, 2015
Background. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients ...

Mechanical Biomimetic Nanocomposites for Multidimensional Treatment of Arterial Thrombosis

Advanced Science, EarlyView.
In this study, a mechanical biomimetic nanocomposite is developed, guided by photoacoustic imaging, to achieve highly efficient and safe thrombolysis through the synergistic effects of photothermal therapy and pharmacological intervention. Most notably, the nanoparticle improves the microenvironment of arterial thrombi, marked by high shear stress and ...

Turbulence to order transitions in activity patterned active nematics [PDF]

Phys. Rev. E 111, 035404 (2025)
We numerically study two-dimensional active nematics with periodic activity patterning. For stripes of activity, we observe a transition from two-dimensional to one-dimensional active turbulence as the maximum active force and distance between activity stripes increases, followed by a transition to stable vortices ordered antiferromagnetically along ...

Active Darcy's Law [PDF]

arXiv, 2023
While bacterial swarms can exhibit active turbulence in vacant spaces, they naturally inhabit crowded environments. We numerically show that driving disorderly active fluids through porous media enhances Darcy's law. While purely active flows average to zero flux, hybrid active/driven flows display greater drift than pure-driven fluids.

Endogenous Near‐Infrared Chemiluminescence: Imaging‐Guided Non‐Invasive Thrombolysis and Anti‐Inflammation Based on a Heteronuclear Transition Metal Complex

Advanced Science, EarlyView.
Cu2Ir NPs based on a Cu‐porphyrin core and cyclometalated Ir(III) substituents achieve combined endogenous peroxynitrite‐triggered NIR chemiluminescence imaging, PTT and PDT for successfully achieving safe thrombolysis, antioxidant and anti‐inflammatory multifunctionality in one single molecule.
