Role of stimulus types and valence on the affective memory performance of adults with anxiety.

Previous studies have found that the emotion of anxiety in adults is easily influence by negative stimuli However, few studies have explored the effect of stimulus types on working memory performance and cognitive processing of adults with anxiety.

Reconstitution of aged bone marrow with young cells repopulates cardiac-resident bone marrow-derived progenitor cells and prevents cardiac dysfunction after a myocardial infarction.

Aims: The study was designed to evaluate the mechanisms of cardiac regeneration after injury and to determine how to restore that capacity in aged individuals. The adult heart retains a small population of nascent cells that have myeloid, mesenchymal, and mesodermal capabilities, which play an essential role in the recovery of ventricular function after injury. In aged individuals, these cells are diminished and dysfunctional.
