Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

Advanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

[Renal transplantation on vascular prosthesis].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 2019
In front of a very calcified aortoiliac axis, renal transplantation with implantation of the artery on vascular prosthesis can be proposed. This rare intervention is considered difficult and morbid. The main objective of this work was to evaluate the overall and specific survival of the transplant in this situation.
