No animal models replicate the complexity of human depression. However, a number of behavioral tests in rodents are sensitive to antidepressants and may thus tap important underlying biological factors. Such models may also offer the best opportunity to discover novel treatments. Here, we used several of these models to test the hypothesis that the acid-sensing ion channel-1a (ASIC1a) might be ...

BACKGROUND Stress exposure is one of the greatest risk factors for psychiatric illnesses like major depressive disorder and posttraumatic stress disorder. However, not all individuals exposed to stress develop affective disorders. Stress resilience, the ability to experience stress without developing persistent psychopathology, varies from individual to individual. Enhancing stress resilience i...

A new operational perspective on fundamental concepts related to customers, service, and value differs from servicedominant logic in its approach to service systems, value creation, value co-creation, service interactions, value facilitation, and value constellations. This perspective leads to two new tools for supporting service system design: 1) A “value blueprint” uses a swimlane representat...

A stress-resistant rat model was introduced. SPORTS (Spontaneously-Running-Tokushima-Shikoku) rats showed significantly shorter time of immobility in the forced swim test compared to control Wister rats. Increase norepinephrine concentration secondary to decreased activity of monoamine oxidase A (MAOA) in hippocampus was observed in this model rats. This model rats are considered to be useful f...

Maternal stress is a common adversity during pregnancy. Gestational corticosterone alternations are thought to contribute to the etiology of postpartum behavioral disturbances. However, the impact of stress during pregnancy, in particular noise exposure, on gestational corticosterone fluctuations and spatial cognition in postpartum mice has not been fully understood yet. We hypothesized that no...

Maximum oxygen consumption (Vo(2)) elicited by swimming in 20 degrees C water or by exposure to -2.5 degrees C in helium-oxygen (Helox) atmosphere is higher in mice selected for low (LA) than for high (HA) stress-induced analgesia (SIA) produced by swimming. However, this line difference is greater with respect to swim- than to cold-elicited Vo(2). To study the relationship between the analgesi...
