Objective(s): Cerebral ischemia/reperfusion (I/R) causes brain inflammation that ultimately causes long time brain function disturbances. We aimed to evaluate the effect of ellagic acid (EA) on anxiety, depression, locomotion behaviors, blood-brain barrier (BBB) permeability, brain edema, and inflammation in male rats with cerebral I/R. Materials and ...

Dopamine neurons in the ventral tegmental area (VTA) are powerful regulators of depression-related behavior. Dopamine neuron activity is altered in chronic stress-based models of depression, but the underlying mechanisms remain incompletely understood. Here, we show that mice subject to chronic mild unpredictable stress (CMS) exhibit anxiety- and depressive-like behavior, which was associated w...

OBJECTIVES Perinatal asphyxia is one of the major cause of mortality in newborns and cause of neurological disorders in adulthood. Brain damage is of the most concern due to high sensitivity of nervous system to suboptimal intrauterine oxygen condition. The aim of this study was to assess effect of subchronic prenatal asphyxia (SPA) during sensitive stages of brain maturation on behavioral chan...

Clinical evidence has indicated a high degree of comorbidity of alcoholism and depression. Manifestation of the depression symptoms during abstinence increases the likelihood of relapse and indicates a worse prognosis in terms of treatment outcome. The depressive symptoms may be alcohol independent or alcohol induced. In this paper, only the ethanol-related depression is the focus of interest. ...

Substantial evidence indicates an association between clinical depression and altered immune function. Systemic administration of bacterial lipopolysaccharide (LPS) is commonly used to study inflammation-associated behavioral changes in rodents. In these experiments, we tested the hypothesis that peripheral immune activation leads to neuroinflammation and depressive-like behavior in mice. We re...

Post-stroke depression is associated with reduced expression of brain-derived neurotrophic factor (BDNF). In this study, we evaluated whether BDNF overexpression affects depression-like behavior in a rat model of post-stroke depression. The middle cerebral artery was occluded to produce a model of focal cerebral ischemia. These rats were then subjected to isolation-housing combined with chronic...

Oxidative stress (OS), which has been implicated in pathogenesis of many acute and chronic diseases, plays an important role in diverse neurological disorders including depression and anxiety. OS is caused by a large amount of reactive oxygen species or impaired enzymatic or non-enzymatic defense against it. OS has been suggested to contribute to etiology of mentioned disorders. This review int...
