Background: Similar to the N-methyl-D-aspartate receptor antagonist ketamine, the metabotropic glutamate 2/3 receptor antagonist, MGS0039, shows antidepressant effects. However, there are no reports comparing these 2 compounds in the social defeat stress model of depression. Methods: We examined the effects of MGS0039 (1 mg/kg) and ketamine (10 mg/kg) on depression-like behavior in susceptible...
Negative symptoms in schizophrenia remain an unmet clinical need. There is no licensed treatment specifically for this debilitating aspect of the disorder and effect sizes of new therapies are too small to make an impact on quality of life and function. Negative symptoms are multifactorial but often considered in terms of two domains, expressive deficit incorporating blunted affect and poverty...
To assess the efficacy of mindfulness-based cognitive therapy (MBCT) for late post-treatment pain in women treated for primary breast cancer. A randomized wait list-controlled trial was conducted with 129 women treated for breast cancer reporting post-treatment pain (score ≥ 3 on pain intensity or pain burden assessed with 10-point numeric rating scales). Participants were randomly assigned to...
Cancer-related fatigue (CRF) is a disruptive symptom for many survivors. Despite promising evidence for efficacy of mindfulness-based stress reduction (MBSR) in reducing CRF, no trials comparing it to an active comparator for fatigued survivors have been published. The purpose of this trial was to compare MBSR to psychoeducation for CRF and associated symptoms. Breast (n = 60) and colorectal (n...
Mindfulness interventions aim to foster greater attention to and awareness of present moment experience.

BackgroundSuicide is the second leading cause of death among 15- to 29-year-olds in China, and 60 % of suicidal patients have a history of depression. Previous brain imaging studies have shown that depression and suicide may be associated with abnormal activity in default mode network (DMN) regions. However, no study has specifically investigated the relationship between DMN functional activity...
Ketamine has been shown to produce rapid and robust antidepressant effects in depressed individuals; however, its abuse potential and adverse psychotomimetic effects limit its widespread use. Dextromethorphan (DM) may serve as a safer alternative on the basis of pharmacodynamic similarities to ketamine. In this proof-of-concept study, behavioral and biochemical analyses were carried out to...
Australian & New Zealand Journal of Psychiatry, 50(11) A recent review in Pharmacological Reviews highlights that over the last decade, a renaissance has occurred in psychedelic drug research in North America and Europe as investigators at Johns Hopkins School of Medicine, University of California, Los Angeles (UCLA), New York University and Imperial College London have embarked on studies that...
Background: Veterans with history of deployment in the Global War on Terror face significant and ongoing challenges with high prevalences of adverse psychological, physical, spiritual, and family impacts. Together, these challenges contribute to an emerging public health crisis likely to extend well into the future. Innovative approaches are needed that reach veterans and their family members...
