Striking long-term beneficial effects of single dose psilocybin and psychedelic mushroom extract in the SAPAP3 rodent model of OCD-like excessive self-grooming.

Obsessive compulsive disorder (OCD) is a highly prevalent disorder that causes serious disability. Available treatments leave 40% or more of people with OCD significantly symptomatic. There is an urgent need for novel therapeutic approaches.

Striking Long Term Beneficial Effects of Single Dose Psilocybin and Psychedelic Mushroom Extract in the SAPAP3 Rodent Model of OCD-Like Excessive Self-Grooming.

Effects of psilocybin, psychedelic mushroom extract and 5-hydroxytryptophan on brain immediate early gene expression: Interaction with serotonergic receptor modulators.

Immediate early genes (IEGs) are rapidly activated and initiate diverse cellular processes including neuroplasticity. We report the effect of psilocybin (PSIL), PSIL-containing psychedelic mushroom extract (PME) and 5-hydroxytryptophan (5-HTP) on expression of the IEGs, , and in mouse somatosensory cortex (SSC). In our initial experiment, male C57Bl/6j mice were injected with PSIL 4.

Effect of chemically synthesized psilocybin and psychedelic mushroom extract on molecular and metabolic profiles in mouse brain.

Psilocybin, a naturally occurring, tryptamine alkaloid prodrug, is currently being investigated for the treatment of a range of psychiatric disorders. Preclinical reports suggest that the biological effects of psilocybin-containing mushroom extract or "full spectrum" (psychedelic) mushroom extract (PME), may differ from those of chemically synthesized psilocybin (PSIL). We compared the effects of PME to those of PSIL on the head twitch response (HTR), neuroplasticity-related synaptic proteins and frontal cortex metabolomic profiles in male C57Bl/6j mice.

COVID-19 vaccination and race - A nationwide survey of vaccination status, intentions, and trust in the US general population.

COVID-19 vaccine hesitancy for adults and children varies depending on societal factors, race, and trust ascribed to the source of vaccine information. To assess COVID-19 vaccination rates and trust levels for vaccine information by race at 2 time points. Online cross-sectional data from US adults were collected in February/March 2021 (T1) and November 2021 (T2).

Could psychedelic drugs have a role in the treatment of schizophrenia? Rationale and strategy for safe implementation.

Schizophrenia is a widespread psychiatric disorder that affects 0.5-1.0% of the world's population and induces significant, long-term disability that exacts high personal and societal cost.

Accuracy of bile duct changes for the diagnosis of chronic liver allograft rejection: reliability of the 1999 Banff schema.

Chronic rejection (CR) after liver transplantation is thought to be a dynamic and potentially reversible process. The Banff working group has developed recommendations for its histopathologic staging. The 1999 Banff classification of CR (i.
