Motivated behaviors are often characterized by a high degree of behavioral activation, and work output organisms frequently make effort-related decisions based upon cost/benefit analyses. Moreover, people with major depression other disorders show motivational symptoms such as anergia, psychomotor retardation, fatigue. It has been suggested that tasks measuring choice behavior could be used animal models the depression, present studies effects vesicular monoamine transport (VMAT) inhibitor...

Depression and related disorders are characterized by deficits in behavioral activation, exertion of effort, other psychomotor/motivational dysfunctions. Depressed patients show alterations effort-related decision making a bias towards selection low effort activities. It has been suggested that animal tests could be useful as models motivational dysfunctions seen psychopathology. Because clinical studies have inhibition catecholamine uptake may strategy for treatment symptoms, the present...

Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations reinforcement value response costs.

We evaluated the processes controlling accumulation of collagen and elastin in main pulmonary arteries rats during an episode hypoxic hypertension. Explant cultures were incubated with [3H]proline to measure protein synthesis percent synthesis. Elastin was measured by [14C]valine incorporation into insoluble elastin. Relative increased twofold (from 1.1 +/- 0.2 x 10(3) 2.0 1.0 disintegrations per minute [14C]hydroxyproline/vessel/hr/mg protein), relative doubled 2% 4-5% total synthesis),...

Abstract Behavioral approaches utilizing rodents to study mood disorders have focused primarily on negative valence behaviors associated with potential threat (anxiety-related behaviors). However, for such as depression, positive that assess reward processing may be more translationally valid and predictive of antidepressant treatment outcome. Chronic corticosterone (CORT) administration is a well-validated pharmacological stressor increases avoidance in anxiety 1–4 . whether chronic stress...
