Functional magnetic resonance imaging (fMRI) was used to measure the effects of acute hypoglycemia caused by passive sensory stimulation on brain activation. Visual stimulation was used to generate blood-oxygen-level-dependent (BOLD) contrast, which was monitored during hyperinsulinemic hypoglycemic and euglycemic clamp studies. Hypoglycemia (50 +/- 1 mg(More)
This study was undertaken to examine whether insulin resistance in adolescents with poorly controlled type 1 diabetes mellitus (T1DM) is associated with the failure of insulin to suppress lipolysis in adipose and muscle tissues. Using microdialysis techniques, extracellular fluid concentrations of glycerol was measured in adipose and muscle tissue 3 h(More)
OBJECTIVE The MiniMed Continuous Glucose Monitoring System (CGMS) measures subcutaneous interstitial glucose levels that are calibrated against three or more fingerstick glucose levels daily. The objective of the present study was to examine whether the relationship between plasma and interstitial fluid glucose is altered by changes in plasma glucose and(More)
