Although previous study has demonstrated that brain-derived neurotrophic factor (BDNF) is involved in the antidepressant-like effect of oleanolic acid, there little information regarding details molecular mechanism this effect.We used a chronic unpredictable mild stress (CUMS) model to test acid on depressant-like behaviour, miR-132 expression and synaptic protein male mouse hippocampus. Furthermore, we explored possible signalling pathways associated with mediate neuronal proliferation.The...

Abstract Previous studies have demonstrated that the mammalian target of rapamycin (mTOR) signaling pathway has an important role in ketamine-induced, rapid antidepressant effects despite acute administration fluoxetine not affecting mTOR phosphorylation brain. However, long-term treatment on modulation been assessed to date. In present study, we examined whether fluoxetine, a type commonly used agent, alters following chronic different brain regions, including frontal cortex, hippocampus,...

Cisplatin, a commonly used chemotherapy drug, can increase the survival rate of cancer patients. However, it often causes various side effects, including neuronal deficit-induced cognitive impairment. Considering that curcumin is effective in protection, action on improvement was evaluated cisplatin-treated C57BL/6 mice present study. Our results first showed restored impaired behaviors. Consistent with this, neurogenesis and synaptogenesis were improved by curcumin. In addition,...

Background . Our previous study has demonstrated that nobiletin could reverse the behavioral alterations in stressed mice. However, relation of its antidepressant-like action with neurotrophic molecular expression remains unknown. This aimed to explore mechanism related system rats exposed chronic unpredictable mild stress (CUMS). Methods Depressive-like anhedonia (assessed by sucrose preference) and serum corticosterone secretion were evaluated CUMS, followed brain-derived factor (BDNF),...

As a classical herb pair in clinics of traditional Chinese medicine, Curcumae Rhizoma-Sparganii Rhizoma (HP CR-SR) is used for activating blood circulation to remove stasis. The essential components HP CR-SR and its single herbs were comparatively analyzed using gas chromatography-mass spectrometry data. 66, 22, 54 volatile oils Rhizoma, Sparganii identified, total contents accounted 75.416%, 91.857%, 79.553% respectively. thirty-eight found CR-SR, not detected Rhizoma. highest radical...

<i>Syzygium aromaticum</i> has been widely used in traditional medicine. Our study investigated the safety and antidepressant-like effects of essential oil <i>S. after acute or long-term treatment. Using GC-MS, a total eight volatile constituents were identified aromaticum</i>. The single LD<sub>50</sub> was approximately 4500 mg/kg based on 24-h oral toxicity study. In repeated this (100, 200, 400 mg/kg, p. o.), only induced significant decrease body weight. addition, no changes relative...

Flavone C-glycosides are difficult to be deglycosylated using traditional chemical methods due their solid carbon-carbon bond between sugar moieties and aglycones; however, some bacteria may easily cleave this because they generate various specific enzymes.A bacterial strain, named W12-1, capable of deglycosylating orientin, vitexin, isovitexin aglycones, was isolated from human intestinal in study identified as Enterococcus faecalis based on morphological examination, physiological...
