Ethanol extract of Pleurotus eryngii (DC.) QUÉL has estrogen-like activities that protect against bone loss caused by estrogen deficiency. In the present study, we investigated the effect of P. eryngii on depression-like behavior and memory impairment in ovariectomized (OVX) rats. Immobility time during a forced swimming test was significantly longer for OVX rats than for sham-operated rats. Th...
Background: Depression is a complicated disturbance affected by a collection of biological and environmental factors. The first aim of psychiatric studies is to recognize biological markers that could be utilized to predict improvement and increase reactions to antidepressant treatments. Diet affects different aspects of health, including depression. The aim of study was to determine antidepres...
The development of animal models with construct, face, and predictive validity to accurately model human depression has been a major challenge. One proposed rodent model is the 5 d repeated forced swim stress (5d-RFSS) paradigm, which progressively increases floating during individual swim sessions. The onset and persistence of this floating behavior has been anthropomorphically characterized a...
BACKGROUND Brain-derived neurotrophic factor (BDNF) and its receptor, tropomyosin-related kinase B (TrkB), signaling represent potential therapeutic targets for major depressive disorder. The purpose of this study is to examine whether TrkB ligands show antidepressant effects in an inflammation-induced model of depression. METHODS In this study, we examined the effects of TrkB agonist 7,8-dih...
Depression and anxiety play an important role in decreasing quality of life worldwide. Since tryptophan is a serotonin precursor and low levels of serotonin seems to be related to depression, the effect of oral tryptophan has been investigated for possible potentiation of the action of antidepressant drugs. We investigated the effects of chronically administered tryptophan (50mg/kg/day, p.o.) w...
background: motherhood is a transformative and pleasing experience in a woman’s life. however, given the physical and psychological changes, it can induce a degree of stress and anxiety in mothers. the aim of the present study was to evaluate the effects of cognitive-behavioral stress management (cbsm) on maternal anxiety and depression during pregnancy and newborns’ apgar scores. methods: this...
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...
A relation between magnesium (Mg) status and mood disorders has been suggested, but evidence remains inconsistent. Therefore, we examined in mice whether Mg-depletion would alter behavior evaluated in established animal models of depression and anxiety and whether these effects would be sensitive to antidepressants. Compared to control mice fed with normal diet, mice receiving a low Mg diet (10...
The orbitofrontal cortex (OFC) is involved in emotional processing, and orbitofrontal abnormalities have often been observed in various affective disorders. Thus, chronic dysfunction of the OFC may cause symptoms of affective disorders, such as anxiety, depression and impulsivity. Previous studies have investigated the effect of orbitofrontal dysfunction on anxiety-like behavior and impulsive a...
