Revealing a Third Dissolved-Phase Xenon-129 Resonance in Blood Caused by Hemoglobin Glycation.

Hyperpolarized (HP) xenon-129 (Xe), when dissolved in blood, has two NMR resonances: one in red blood cells (RBC) and one in plasma. The impact of numerous blood components on these resonances, however, has not yet been investigated. This study evaluates the effects of elevated glucose levels on the chemical shift (CS) and T2* relaxation times of HP Xe dissolved in sterile citrated sheep blood for the first time.

Humour mediates the facilitative effect of bizarreness in delayed recall.

The first empirical study focused exclusively on the influence of bizarre elaboration on memory (Delin, 1968) indicated a significant relationship between bizarreness and recall after a 15-week delay. However, that study was strongly criticized on methodological grounds. The present study offers a conceptual replication of Delin's historically significant study which sought to verify his influential, yet criticized, results and to test the possibility that a humour response mediates the relationship between bizarre elaboration and recall using multiple regression procedures.
