As key molecular chaperone proteins, heat shock proteins (HSPs) represent an important cellular protective mechanism against neuronal cell death in various models of neurological disorders. In this study, we investigated the effect as well as the molecular mechanism of geldanamycin (GA), an inhibitor of Hsp90, on 1-methyl-4-pheny-1,2,3,6-tetrahydropyridine(More)
OBJECTIVE High level of impulsivity as well as depression is thought to be involved in the maintenance and development of methamphetamine (METH) addiction. However, the relationship between impulsivity and depression has not been studied thoroughly in METH dependence subjects, especially in early METH abstinent subjects. In this study, our objective is to(More)
The high prevalence of smoking in schizophrenia of European background may be related to smoking's reducing clinical symptoms and medication side effects. Because smoking prevalence and its associations with clinical phenotypes are less well characterized in Chinese than European patients with schizophrenia, we assessed these smoking behaviors using(More)
There is evidence that adenosine acting at A(2A) receptors (A(2A)R) can influence striatal plasticity and cognitive functions. We examined spatial working memory in wild-type (WT) and A(2A) receptor knock-out (KO) mice using two assessments: the eight arm radial maze and a repeated trial Morris water maze (MWM) paradigm. Compared to WT littermates, A(2A)R(More)
Caffeine is well known for its complex pharmacological actions, in part reflecting the multiple molecular targets of caffeine. The adenosine receptors are the primary extracellular targets of caffeine. Since caffeine has similar affinity for several adenosine receptors, it has been difficult to determine which receptor subtypes mediate caffeine's effects(More)
Studies with multiple sclerosis patients and animal models of experimental autoimmune encephalomyelitis (EAE) implicate adenosine and adenosine receptors in modulation of neuroinflammation and brain injury. Although the involvement of the A(1) receptor has been recently demonstrated, the role of the adenosine A(2A) receptor (A(2A)R) in development of EAE(More)
Excessive free radical production or oxidative stress may be involved in the pathophysiology of schizophrenia as evidenced by increased superoxide dismutase (SOD) activities, a critical enzyme in the detoxification of superoxide radicals. This study compared plasma SOD activities in 78 never-medicated first-episode and 100 medicated chronic schizophrenia(More)
Brain-derived neurotrophic factor (BDNF) has been implicated in the pathophysiology of opiate addiction. Both increased and decreased serum BDNF levels have been reported in heroin addicts. Moreover, the role of BDNF in heroin-dependent patients during withdrawal has not been studied. This study aimed to explore the differences in serum BDNF levels of(More)
BACKGROUND 20 million migrant workers in China lost their jobs during the economic crisis of 2008. Both urban migration and unemployment have long been documented to be associated with vulnerability to mental problems. This study aims to examine the mental health of unemployed migrant workers in Eastern China and its relation to duration of unemployment and(More)
OBJECTIVE This study aimed to determine the effects of cognitive emotion regulation strategies on depressive symptoms in women with breast cancer. METHODS Five hundred and nine women with breast cancer completed a demographic survey, the Chinese version of Cognitive Emotion Regulation Questionnaire (CERQ-C), and the Center for Epidemiological Studies(More)
