Magnetic resonance-defined periportal steatosis following intraportal islet transplantation: a functional footprint of islet graft survival?

abstract：:More than 120 published reports have described associations between single nucleotide polymorphisms (SNPs) and type 2 diabetes. However, multiple studies of the same variant have often been discordant. From a literature search, we identified previously reported type 2 diabetes-associated SNPs. We initially genotyped 1...
