Is non-heart-beating organ donation too aggressive?

The protocol here describes a high-fidelity porcine model of heart transplantation following donation after circulatory death utilizing ex vivo perfusion of the allograft.

The present study shows the establishment of three different lung donation models (post-brain death donation, post-circulatory death donation, and post-hemorrhagic shock donation). It compares the inflammatory processes and pathological disorders associated with these...

This protocol shows a simple and flexible approach for the evaluation of new conditioning agents or strategies to increase the feasibility of cardiac donation after circulatory...

Technique required for visualizing the beating heart in larval and adult Drosophila are presented. Each life stage requires a different...

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression.
