Ketamine is a non-competitive antagonist of the N-methyl-D-aspartate (NMDA) glutamate receptor that is both a drug of abuse and an FDA-approved anesthetic used off-label for treatment-resistant depression. Despite its growing clinical use for depression and pain, the relationships between the acute dissociative and affective effects of ketamine that contribute to its abuse liability and...
Ketamine is a dissociative anesthetic used in veterinary and human medicine since the 1970s. Its clinical use has expanded to control of seizures, by pre-hospital emergency medical services (EMS), and is finding new purpose as an analgesic alternative and antidepressant. Ketamine brings hope for effective management of chronic pain in the absence of opioids and decreasing suicidal ideations;...
Abstract. After decades of stagnation, research on psychedelic substances (such as lysergic acid diethylamide [LSD], psilocybin, or N,N-dimethyltryptamine [DMT]) has experienced a renaissance over the last 10 years, with various major research programs being conducted across Europe and the United States. This research primarily investigates the potential of psychedelics in the treatment of...
Curcumin as an antioxidant natural herb has shown numerous pharmacological effects. However, the poor bioavailability of curcumin is a significant pharmacological barrier for its antioxidant activities. The present study was conducted to develop curcumin-loaded nanophytosome (CNP) and explore their therapeutic potential in a ketamine (KET)-induced schizophrenia (SCZ) model. The mice in our...
Psychedelic drugs (also called hallucinogens, psychotogenics, psycholytics, entheogens) are substances that act mainly on the 5-HT2 serotonergic receptor.There are two main groups of psychedelics: indoleamines (lysergic acid diethylamide-LSD, N, N-dimethyltryptamine-DMT, and psilocybin) and phenethylamines (mescaline, dimethoxymethamphetamine-DOM, methylenedioxyamphetamine-MDA, and...
Although psychoanalysts are interested in symptom reduction as an outcome, they are looking for instruments to measure sustaining changes in the unconscious mental functioning. In this article it is discussed that conceptually well-founded transformation of manifest dreams analyzed with precise empirical methods could be considered as a promising indicator for such therapeutic changes. We are...

To investigate the effects of ketamine on glucose uptake and glucose transporter (GLUT) expression in depressive-like mice. After HA1800 cells were treated with ketamine, 2-[N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino]-2-Deoxyglucose (2-NBDG) was added to the cells to test the effects of ketamine on glucose uptake, production of lactate, and expression levels of GLUT, ERK1/2, AKT, and AMPK....
Abstract Rationale Lysergic acid diethylamide (LSD) is used in psychiatric and psychological research and investigated as a potential treatment for medical and psychiatric disorders, including depression, anxiety, and cluster headache. Objectives Safety data on clinical safety are available from small studies but not from larger samples. We report safety pharmacology data from a large pooled...
Objectives: A substantial proportion of trauma survivors with posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) continue to experience symptoms even after trauma-focused therapies. Internet-based interventions could facilitate access to treatment for PTSD and CPTSD. The current pilot study aimed to investigate the effects of mindfulness-based internet intervention on PTSD and CPTSD...
The publication in April 2021 of the Imperial College London Phase II study investigating \nthe efficacy of psilocybin-assisted therapy vs. escitalopram for depression reported differences \nin the primary outcome measure (the QIDS-SR16) between experimental and control arms as \nstatistically insignificant (1). However, secondary measures of depression, and other relevant \nmeasures (see...
