Expanded epithelial surrogates termed enteroids may serve as a potential donor source.
One rodent model that has been used as a surrogate in terms of OA pain is CFA injection into the knee joint.
The two blocks of traditional uncertainty to standard health economic evaluations are first of all associated to the fact that the missing link between short-term surrogate endpoints and the long-term hard outcome is usually not established through a RCT, but can be based on observational cohort studies or case control studies.
Conversely, sparse gels (≤1 mg/ml), which are extensively used in 3D cultures, failed to reproduce the hindered diffusion of tissues, thereby supporting that dense (but not sparse) ECM gels are suitable tissue surrogates in terms of macromolecular transport.
The study investigated how land use change affects the status of the biodiversity surrogates in terms of the loss or gain of habitat (areal extent), loss of habitat condition (degradation) and habitat fragmentation.
Using a synthetic groundwater flow model, this study evaluates the log-likelihood and head surrogates in terms of the computational cost of building them, the accuracy of the surrogates, and the accuracy of the distributions of model parameters and predictions obtained using the surrogates.
These surrogates are termed Erdös 1 surrogates, meaning that they are one degree removed from the proband on the basis of haplotype identity [ 6].
While children in developing countries may serve as good surrogates in terms of immune naïveté, there may be important differences in pathogen exposure, environment, host-response and risk behavior that may impact the direct generalization of risk to U.S. military populations.
Lastly, while the evidence showed that metformin had favorable effects across all three components of HALS, whether these short-term, surrogate changes will translate to long-term clinical benefits is not known.
