Aromatase inhibition and ketamine in rats: sex-differences in antidepressant-like efficacy

Biology of Sex Differences October 24, 2023 Sandra Ledesma-Corvi, Jordi Jornet-Plaza, M. García-Fuster

Ketamine is a novel fast-acting antidepressant recently approved for treatment-resistant depression. Since preclinical studies showed sex differences in its efficacy, probably driven by sex hormones (estrogens and testosterone), we evaluated the antidepressant-like effects of ketamine in male and female rats when the biosynthesis of estrogens was inhibited. To do so, we utilized letrozole, an...

Cardiovascular safety of psychedelic medicine: current status and future directions

Pharmacological Reports October 24, 2023 Agnieszka Wsół 56 citations

Abstract Psychedelics are powerful psychoactive substances that alter perception and mood processes. Their effectiveness in the treatment of psychiatric diseases was known before their prohibition. An increasing number of recent studies, due to the indisputable resurgence of serotonergic hallucinogens, have shown their efficacy in alleviating depression, anxiety, substance abuse therapies, and...

The Effects of Neuroscience-Based Mindfulness Training on Adolescents

International Journal of Education and Literacy Studies October 20, 2023 Ezgi Özeke-Kocabaş, Bengisu Koyuncu 1 citation

This preliminary study aims to address situations such as high anxiety, stress, inability to focus, and physical burnout experienced by students in the exams made during the transition to a higher education process in the educational system. It also aims to contribute to the development of students’ academic and social-emotional skills, in other words emotional literacy through mindfulness...

Breaking bad buttons: mescaline biosynthesis in peyote

The Plant Journal October 20, 2023 Gwendolyn K. Kirschner 2 citations

The small, globular cactus peyote (Lophophora williamsii) is known for its ability to produce mescaline, a phenethylamine protoalkaloid (Figure 1). Consuming the mescaline-containing dried tops or “buttons” of peyote has a psychedelic effect that has been used in religious ceremonies by Indigenous communities for over 5800 years (Cassels & Sáez-Briones, 2018). Nowadays, psychedelic drugs are...

The feasibility and acceptability of an online mind-body wellness program for patients with primary biliary cholangitis

Canadian Liver Journal October 19, 2023 Makayla Watt, Ashley Hyde, John C. Spence et al. 9 citations

Background: Persons with primary biliary cholangitis (PBC) experience significantly higher rates of mental distress and impaired health related quality of life (HrQoL) than the general population. Given limited evidence, but a high need, our primary aim was to assess feasibility and acceptability of a 12-week, online, mind–body wellness program in people with PBC. Methods: This was a...

Abstract Objectives The COVID-19 pandemic has caused high mortality rates worldwide, as well as consequent psychological and physical stress. The present study aimed to review the main existing scientific research studies conducted since the onset of the COVID-19 that have used mindfulness-based interventions (MBIs) as tools for emotional regulation, aiming to improve individuals’ ability to...

Small-Molecule Heterocyclic Compounds: Gq-Biased Agonists for the 5-HT2A Receptor in Neuropsychiatric Treatment

ACS Medicinal Chemistry Letters October 19, 2023 Robert B. Kargbo 2 citations

Addressing the significant challenges of treating depression, anxiety, and substance abuse, this Patent Highlight explores the development of innovative small-molecule heterocyclic compounds as Gq-biased agonists of the 5-HT2A receptor. Unlike traditional treatments, these compounds selectively activate 5-HT2A-mediated Gq signaling, excluding related receptors like 5-HT2B and 5-HT2C. This...

Ketamine’s acute effects on negative brain states are mediated through distinct altered states of consciousness in humans

Nature Communications October 19, 2023 Laura M Hack, Xue Zhang, Boris D. Heifets et al. 20 citations

Ketamine commonly and rapidly induces dissociative and other altered states of consciousness (ASCs) in humans. However, the neural mechanisms that contribute to these experiences remain unknown. We used functional neuroimaging to engage key regions of the brain’s affective circuits during acute ketamine-induced ASCs within a randomized, multi-modal, placebo-controlled design examining placebo,...

Effects of psilocybin, the 5-HT2A receptor agonist TCB-2, and the 5-HT2A receptor antagonist M100907 on visual attention in male mice in the continuous performance test.

Psychopharmacology October 19, 2023 Arya Rahbarnia, Zhaoxia Li, Paul J Fletcher 9 citations

Neuropsychiatric disorders such as depression are characterized in part by attention deficits. Attention is modulated by the serotonin (5-HT) neurotransmitter system. The 5-HT2A agonist and hallucinogen psilocybin (PSI) is a promising treatment for disorders characterized by attention changes. However, few studies have investigated PSI's direct effect on attention. Using the rodent continuous...
