Surface modification of 3D‐printed polycaprolactone scaffolds with silk fibroin for bone tissue engineering

FEBS Open Bio, EarlyView.
Coating 3D‐printed PCL scaffolds with silk fibroin can improve biocompatibility and bone cell adhesion. One innovative design for tissue‐engineering scaffolds uses 3D printing technology. Here, we used polycaprolactone (PCL) filament as a biocompatible material to design a porous 3D scaffold for bone tissue engineering.

Bioprostheses and Mechanical Prostheses for Aortic Valve Replacement in Patients Aged 50 to 65 Years Offer Similar Long-Term Survival Rates

Journal of Cardiovascular Development and Disease
Background: Aortic valve replacement (AVR) is the definitive therapy for patients with severe aortic valve stenosis (AoS). The aim of this work is to compare the effect of a mechanical prosthesis (MP) and a bioprosthesis (BP) on the survival of patients ...

Fulminant thrombosis of mechanical mitral valve prosthesis [PDF]

Heart, 2001
In patients with prosthetic heart valves non-cardiac surgery may require temporary discontinuation of oral anticoagulation. Although the risk of valve related thromboembolic complications may generally be only slightly increased during the short perioperative period, in the presence of certain risk factors, replacement of oral anticoagulation with ...

Microstructural Evolution and In Situ Formation of TiB and TiC in Ti─5Al─2.5Sn Alloy Processed by Powder Metallurgy

Advanced Engineering Materials, EarlyView.
Accelerated in situ formation of TiB and TiC in Ti–5Al–2.5Sn–B4C is driven by transient liquid phase formation, which enhances particle reactions and microstructural evolution. This process increases hardness and establishes a coupled relationship between sintering temperature and reinforcement content, strongly influencing porosity in the resulting ...
