AIM The effect of a depression-like status formed by chronic stress on the development of Lewis lung carcinoma metastases in C57Bl/6J mice was investigated. Two types of acute stress (restraint and social stress) were used for comparison. METHODS The depression-like status was induced by eight-week exposure to repeated but unpredictable stressors (chronic mild stress model) and was assessed i...
The neurogenesis hypothesis of major depression has two main facets. One states that the illness results from decreased neurogenesis while the other claims that the very functioning of antidepressants depends on increased neurogenesis. In order to verify the latter, we have used cyclin D2 knockout mice (cD2 KO mice), known to have virtually no adult brain neurogenesis, and we demonstrate that t...
Oxytocin stimulates adult neurogenesis even under conditions of stress and elevated glucocorticoids.
Oxytocin has been linked to social behavior, including social recognition, pair bonding and parenting, but its potential role in promoting neuronal growth has not been investigated. We show here that oxytocin, but not vasopressin, stimulates both cell proliferation and adult neurogenesis in the hippocampus of rats. Oxytocin is also capable of stimulating adult neurogenesis in rats subjected to ...
Stress hormones released in the CNS following exposure to unavoidable, aversive stimuli have been shown to alter the physiology of neurons in multiple brain regions including hippocampus, amygdala, prefrontal cortex, and ventral tegmental area. The nucleus accumbens (NAc), a motor-limbic interface linked to motivation and reward, receives inputs from each of these stress-affected brain regions,...
Introduction: In this study, we investigated whether neurofeedback (NFB) training and swimming exercise would decrease the electroencephalographic (EEG) changes visual image-induced craving in methamphetamine (METH)-dependent patients. Methods: This study was a randomized controlled trial design. 32 METH-dependent patients were allocated randomly to four groups; control, NFB, Swim, NFB/Swim. Th...
Background: Stress predisposes organisms to depression and cognitive impairments, and seems to interact with metabolic homeostasis. The inflammatory response and the upregulation of proinflammatory cytokines are some of the consequences related to chronic stress. In this study, we investigated the preventive effect of chronic administration of ibuprofen, as an inhibitor of cyclooxygenases, on t...
INTRODUCTION Bacopa monniera/ Brahmi,is used over centuries in Ayurvedic medicine for memory development, learning, concentration and other mental illnesses such as nervousness and poor cognition. The present study aims to evaluate the effect of Bacopa monniera (Brahmi, BM) on cold stress induced histological changes in hippocampus of Wistar rats. MATERIALS AND METHODS Total 24 male rats divi...
