A mathematical model for foreign body reactions in 2D [PDF]

International Journal of Computer Mathematics, 2011
The foreign body reactions are commonly referred to the network of immune and inflammatory reactions of human or animals to foreign objects placed in tissues. They are basic biological processes, and are also highly relevant to bioengineering applications in implants, as fibrotic tissue formations surrounding medical implants have been found to ...

Abscess formation caused by a foreign body reaction to a poly-d, l-lactic acid (PDLLA) absorbable plate for zygomaticomaxillary complex (ZMC) fracture

Bulletin of the National Research Centre, 2022
Background The poly-d, l-lactic acid absorbable plate does not contain poly l-lactic acid, which is the main factor in foreign body reactions; therefore, with use of this plate, a foreign body reaction is unlikely.
