During two epidemics of acute diarrhoea in China in late 1982/early 1983, more than 12 000 adults in two coal mining districts were affected. The virus isolated from stool samples resembled a rotavirus morphologically. Antigenically it lacked the group antigen shared by known rotaviruses. Like other rotaviruses it had a double-stranded RNA with 11 discrete(More)
In this study, we investigated the antidepressant-like effect of piperine in mice exposed to chronic mild stress (CMS) procedure. Repeated administration of piperine for 14 days at the doses of 2.5, 5 and 10 mg/kg reversed the CMS-induced changes in sucrose consumption, plasma corticosterone level and open field activity. Furthermore, the decreased(More)
Although recent studies have suggested that the microfilament (MF) cytoskeleton of plant cells participates in the response to salt stress, it remains unclear as to whether the MF cytoskeleton actually plays an active role in a plant's ability to withstand salt stress. In the present study, we report for the first time the role of MFs in salt tolerance of(More)
In the present study, antidepressant-like effects of piperine (PIP) and its derivative, antiepilepsirine (AES), were investigated in two depressive models: forced swimming test (FST) and tail suspension test (TST). To further explore the mechanisms underlying their antidepressant-like activities, the brain monoamine levels and monoamine oxidase A and B(More)
Exposure to chronic stress in rodents and psychosocial stress in humans has been shown to alter cognitive functions and has been linked to the pathophysiology of mood disorders. The purpose of the present study was to investigate effects and possible mechanisms of a chronic mild stress (CMS) procedure on cognitive behaviors in Swiss albino mice using the(More)
Microtubule-associated proteins (MAPs) play important roles in the regulation of microtubule function in cells. We describe Arabidopsis thaliana MAP18, which binds to microtubules and inhibits tubulin polymerization in vitro and colocalizes along cortical microtubules as patches of dot-like structures. MAP18 is expressed mostly in the expanding cells. Cells(More)
Although the results of some studies indicate that salt stress affects the organization of microtubules, it remains an open question whether microtubules play an active role in the plant's ability to withstand salt stress. In the present study, we showed that salt stress-induced wild-type Arabidopsis seedling roots display right-handed skewed growth and(More)
We previously demonstrated that evodimine isolated from Evodia rutaecarpa (Goshuyu in Japan) induced apoptosis in human malignant melanoma A375-S2 cells within 24 h. In this study, TUNEL assay also indicated that one cause of A375-S2 cell death induced by evodiamine was apoptosis. After treatment with evodiamine for the indicated time periods,(More)
The novel polysaccharide SeGLP-2B-1 isolated from Se-enriched Ganoderma lucidum, showed anti-proliferative activity towards several cancer cell lines in vitro. To investigate the antitumor mechanisms, the apoptotic effects of SeGLP-2B-1 in human breast cancer cells were studied, and the mechanism of this action was further elucidated. Cell apoptosis was(More)
