Vaporized N,N-dimethyltryptamine (DMT) produced rapid and sustained antidepressant effects in a small open-label trial of six people with treatment-resistant depression. Depression severity, measured by the Montgomery-Asberg depression rating scale (MADRS) and Patient Health Questionnaire-9 (PHQ-9), decreased significantly from the first day through one month after dosing. The average MADRS score dropped by 22 points at day 7 and 17 points at one month. By day 7, 83.33% of patients responded to treatment and 66.67% achieved remission; at one month, 66.67% maintained response and 50% maintained remission. The short-acting, noninvasive vaporized route may improve accessibility to psychedelic treatments.
The plastid genome of Mimosa tenuiflora (Jurema-Preta) is 165,639 base pairs long with a typical quadripartite structure and 130 protein-coding genes. Its mitochondrial genome is 617,839 base pairs, contains 107 protein-coding genes, and shows complex structural rearrangements from large repeats, including transferred plastid genes and sequences from non-retroviral RNA mitoviruses. Comparative analysis across Fabaceae species indicates limited conservation, highlighting the dynamic evolution of plant mitochondrial genomes. Phylogenetic placement confirms M. tenuiflora within Caesalpinioideae, closely related to M. pigra and M. pudica. The genomic characterization provides insights for evolutionary studies, population genetics, and potential ethnopharmacological applications.
