The psychedelic-peptide paradox: a hormetic hypothesis.
Compr Psychoneuroendocrinol – June 02, 2025
Summary
Powerful compounds can yield unexpected benefits at very low doses. A new theory proposes that psychedelics, despite their potent effects, may operate through a "hormetic" mechanism. This means tiny amounts could trigger positive biological responses, akin to how exercise strengthens the body. The concept suggests specific peptides might mediate these beneficial actions, offering a fresh perspective on their therapeutic potential. This highlights the subtle, positive ways these substances interact with biology.

Using isoflurane to determine MAC and KXA (ketamine/xylazine/acepromazine) for injectable anesthesia, scientists monitored HR, RR, and SpO2. They found male mice showed a significantly longer loss of righting reflex (LORR) and surgical plane duration with KXA. While isoflurane MAC was consistent, heart rate differences emerged between substrains, with some showing lower HR. These findings highlight crucial sex-specific anesthetic responses and physiological variations.
Abstract
Anesthesia is commonly performed with mice in the research setting. Standard doses of anesthetic drugs are typically recommended, without customiza...
Ketamine's double-edged sword: Therapeutic benefits and adverse events in adolescent treatment-resistant OCD - A case series.
Indian journal of psychiatry – June 01, 2025
Summary
For one-third of individuals, severe OCD resists standard treatments. A new investigation explored ketamine's potential, as it influences glutamate, a brain chemical linked to OCD. In a case series, four adolescents with treatment-resistant obsessive-compulsive disorder received ketamine, an NMDA antagonist. Remarkably, three showed significant, lasting improvement. However, one experienced transient adverse effects, including psychosis. This suggests ketamine holds promise for adolescent treatment-resistant OCD, despite requiring careful consideration of risks.
Abstract
About one-third of obsessive-compulsive disorder (OCD) cases show poor response to first-line treatments. Ketamine's role in modulating glutamate, ...
Impact of a Momentary Mindfulness Intervention on Rumination, Negative Affect, and their Dynamics in Daily Life.
Affective science – June 01, 2025
Summary
Brief moments of mindfulness can significantly reduce negative thought patterns like rumination. A micro-randomized trial using ambulatory assessment investigated if short mindfulness interventions in daily life could lessen rumination and negative affect. Participants received smartphone prompts, completing either a mindfulness exercise or a control task, then reported their feelings. Results show these interventions successfully lowered both rumination and negative affect, suggesting a promising approach to improve daily emotional well-being.
Abstract
Rumination and negative affect are mutually reinforcing experiences. Their dynamic relation can confer vulnerability to psychopathology. Cultivatin...
COVID-19-Associated Cytotoxic Lesions of the Corpus Callosum in Chinese Patients: A Retrospective Study.
Brain and behavior – June 01, 2025
Summary
Brain inflammation linked to SARS-CoV-2 can affect the corpus callosum, a vital bridge between brain hemispheres. Chinese researchers found that patients with this rare inflammatory encephalopathy showed promising recovery when treated promptly. Advanced neuroimaging revealed distinct patterns in eight patients, with most experiencing fever before neurological symptoms. After treatment, seven patients showed significant improvement within two weeks.
Abstract
Cytotoxic lesions of the corpus callosum (CLOCCs) are a rare clinicoradiologic syndrome, exceptionally rare in association with coronavirus disease...

Exploring Gender-Themed Lysergic Acid Diethylamide Experiences: A Subreddit Analysis.
Psychedelic medicine (New Rochelle, N.Y.) – June 01, 2025
Summary
Intriguingly, some people find LSD helps clarify their gender identity. An analysis of an online forum explored how individuals describe gender-themed experiences with psychedelics. Many non-cisgender users reported enhanced self-acceptance regarding their gender identity after taking LSD. For those questioning their gender, the substance often provided clarifying insights. Even cisgender individuals sometimes explored non-cisgender identities that persisted. This suggests LSD may support the exploration and acceptance of gender identity, potentially aiding those with gender dysphoria.
Abstract
Gender-themed lysergic acid diethylamide (LSD) experiences have been documented anecdotally but not yet studied systematically. This study aimed to...
