Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

Plasma Levels of t-PA and PAI-1 Correlate With the Formation of Experimental Post-Surgical Peritoneal Adhesions

Mediators of Inflammation, 2006
This study has evaluated whether systemic changes of plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) parallel the adhesions development and whether they could be used as predictors of adhesion risk.

Multi-Label Activity Recognition using Activity-specific Features and Activity Correlations [PDF]

arXiv, 2020
Multi-label activity recognition is designed for recognizing multiple activities that are performed simultaneously or sequentially in each video. Most recent activity recognition networks focus on single-activities, that assume only one activity in each video.

Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

Advanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.

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.

Hydrophobin‐Coated Echogenic Microbubbles for Molecular Targeting of Tumor Cells

Advanced Science, EarlyView.
Echogenic microbubbles based on hydrophobin and corresponding fusion protein (HFBI‐domZ) are developed as contrast agents for cancer diagnostics. Hydrophobin provides high stabilization of encapsulated perfluoro‐n‐butane, and fusion proteins allow further versatile functionalization with antibodies. In‐vitro experiments indicate that these microbubbles

A novel activity pattern generation incorporating deep learning for transport demand models [PDF]

arXiv, 2021
Activity generation plays an important role in activity-based demand modelling systems. While machine learning, especially deep learning, has been increasingly used for mode choice and traffic flow prediction, much less research exploiting the advantage of deep learning for activity generation tasks.

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

Advanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

Functional, pathogenic, and pharmacological roles of protein folding intermediates

Proteins: Structure, Function, and Bioinformatics, EarlyView., 2023
Abstract Protein expression and function in eukaryotic cells are tightly harmonized processes modulated by the combination of different layers of regulation, including transcription, processing, stability, and translation of messenger RNA, as well as assembly, maturation, sorting, recycling, and degradation of polypeptides.

The development of nasal polyps involves early middle meatus mucous remodeling via TGF-β1 mediated PAI-1 reduction

Brazilian Journal of Otorhinolaryngology, 2023
Objective: Our study aimed to elucidate the effect of PAI-1 (Plasminogen Activator Inhibitor-1) and t-PA (Tissue-type Plasminogen Activator) in tissue remodeling in nasal polyps patients. Methods: Samples were streamed as early Nasal Polyps (eNP, n = 10)
