Influence of Cracking on Oxygen Transport in UHPFRC Using Stainless Steel Sensors

Applied Sciences, 2019
Reinforced concrete elements frequently suffer small cracks that are not relevant from the mechanical point of view, but they can be an entrance point for aggressive agents, such as oxygen, which could initiate the degradation processes. Fiber-Reinforced

Allogeneic Immune Cell Perfusion Inhibits the Growth of Vascularized 3D In Vitro Tumor Models, Induces Vascular Regression and Desmoplasia, but Promotes Tumor Cell Invasion

Advanced Science, EarlyView.
This study presents a vascularized 3D tumor model to investigate immune–stromal–tumor interactions under allogeneic PBMC perfusion. While immune cells induced tumor shrinkage, they also promoted vascular regression, stromal activation, and cancer cell invasion.

Ultra High Performance Concrete - A Technical Study

, 2023
The obligations imposed on the construction sector enhanced awareness of various concrete difficulties. These problems include the unevenness and instability of the matrix, as well as its poor durability, high weight-to-strength ratio, low ductility, and low tensile to compressive strength ratio. In 1994, employing an optimum particle size distribution

The FOXC2‐LAMA4 Axis Orchestrates Vasculogenic Mimicry and Immunosuppressive Niche Formation to Drive Metastatic Cascade in Renal Cell Carcinoma

Advanced Science, EarlyView.
Advanced clear cell renal cell carcinoma metastasis is driven by a FOXC2+ tumor subpopulation. These cells execute vasculogenic mimicry for dissemination and secrete LAMA4. LAMA4 engages macrophage ITGA6, activating the STAT6/GATA3 axis to polarize macrophages into a pro‐metastatic, immunosuppressive phenotype.

Monitoring the reduction in shrinkage cracking of mortars containing superabsorbent polymers [PDF]

, 2017
Ultra-high performance concrete (UHPC) is characterized by a low water-to-cement ratio, leading to improved durability and mechanical properties. However, the risk for autogenous shrinkage and cracking due to restrained shrinkage increases, which may ...
