A universal strategy for the construction of polymer brush hybrid non-glutaraldehyde heart valves with robust anti-biological contamination performance and improved endothelialization potential.

Acta Biomaterialia, 2023
With the intensification of the aging population and the development of transcatheter heart valve replacement technology (THVR), clinical demand for bioprosthetic valves is increasing rapidly. However, commercial bioprosthetic heart valves (BHVs), mainly

Contamination distribution and non-biological removal pathways of typical tetracycline antibiotics in the environment: A review.

Journal of Hazardous Materials, 2023
While the occurrence and removal technologies of tetracyclines in the environment have been reported, a comprehensive systematic summary and analysis remain limited, especially for new generations compounds such as doxycycline. In this review, the latest

Modelling and simulations of particle resuspension and transport for the assessment of terrestrial-borne biological contamination of the samples on the mars 2020 mission

, 2020
The Mars 2020 mission aims to answer key questions about the potential for life on Mars, in part, by searching for signs of past microbial life. Soon after landing, a rover similar to Curiosity will acquire scientifically selected samples of martian ...

Experiments in particle resuspension and transport for the assessment of terrestrial-borne biological contamination of the samples on the mars 2020 mission

, 2020
A collection of first-principles models of all known contamination vectors has been developed to assess our ability to meet the stringent requirements for the biological contamination of the soil and rock samples that will be collected during the Mars ...

Biological contaminants

Journal of Allergy and Clinical Immunology, 1994
"The potential economic impact of indoor air pollution is quite high and is estimated in the tens of billions of dollars per year. Such impacts includes direct medical costs and lost earnings due to major illness as well as increased employee sick days and lost productivity." The health consequences of biological contamination range from uncomfortable ...
