Objective: To compare bursting strength, construction time, and anastomotic dimensions of 4 jejunoileal anastomotic techniques.
Study Design: Experimental ex vivo study.
Animals: Adult horses (n = 12).
Background: When analyzing complex biological systems, a major objective is localization of function - assessing how much each element contributes to the execution of specific tasks. To establish causal relationships, knockout and perturbation studies are commonly executed. The vast majority of studies perturb a single element at a time, yet one may hypothesize that in non-trivial biological systems single-perturbations will fail to reveal the functional organization of the system, owing to interactions and redundancies.

Previous investigations have used comprehensive single and double gene knockouts to study gene essentiality and pairwise gene interactions in the yeast Saccharomyces cerevisiae. Here we conduct an in silico multiple knockout investigation of a flux balance analysis model of the yeast's metabolic network.
