Glucose transport during PD is thought to occur via inter-endothelial pathways, but recent results show that phloretin, a general blocker of facilitative glucose channels (glucose transporters [GLUTs]), markedly reduced glucose diffusion capacity indicating that some glucose may be transferred via facilitative glucose channels (GLUTs). Whether such transport mainly occurs into (absorption), or across (trans-cellular) peritoneal cells is as yet unresolved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Here we sought to elucidate whether diffusion of radiolabeled\n                      <jats:sup>18<\/jats:sup>\n                      F-deoxyglucose ([\n                      <jats:sup>18<\/jats:sup>\n                      F]-DG) in the opposite direction (plasma \u2192 dialysate) is also affected by GLUT inhibition.
