Buprenorphine Microdosing for the Pain and Palliative Care Clinician

Journal of Palliative Medicine December 20, 2021 Kyle Quirk, Maximillian H. Stevenson

Buprenorphine (BUP) can be a safe and effective alternative to traditional opioids for many patients with chronic pain. For patients on higher doses of opioids, rotation to BUP is complicated by the requirement of an opioid-free interval or withdrawal during the transition. Microdosing inductions, in which BUP is gradually titrated, while full agonist opioids are continued, are a viable...

No evidence that LSD microdosing affects recall or the balance between distracter resistance and updating

bioRxiv Preprint Server December 2, 2021 Sean James Fallon 2 citations preprint

The effect of low doses (<=20 μg) of LSD on working memory, in the absence of altered states of consciousness, remain largely unexplored. Given its possible effects on serotonin 5-HT2A receptors and dopaminergic signalling, it could be hypothesised that LSD microdoses modulate working memory recall. Moreover, in line with computational models, LSD microdoses could exert antagonistic effects on...

Abstract 1311: PET-MRI microdosing can determine the delivery of the experimental cancer therapeutic, MN-anti-miR10b, to metastatic lesions in a murine model of breast cancer

Cancer Research July 1, 2021 Marianne Le Fur, Byunghee Yoo, Nicholas Rotile et al.

Abstract: Conventional therapies, which are effective against primary cancer, oftentimes are not successful at treating metastatic cancer. In our earlier work, we identified miRNA-10b as a master regulator of the viability of metastatic tumor cells. This knowledge allowed us to design a miR-10b inhibitor, termed MN-anti-miR10b, capable of delivery to metastatic sites via intravenous injection....

Microdosing psychedelics and its effect on creativity: Lessons learned from three double-blind placebo controlled longitudinal trials

June 14, 2021 Luisa Prochazkova, Michiel van Elk, Josephine Marschall et al. 4 citations preprint

Introduction: Microdosing refers to the repetitive administration of tiny doses of psychedelics (LSD, Psilocybin) over an extended period of time. This practice has been linked to alleged cognitive benefits, such as improved mood and creativity, potentiated by targeting serotonergic 5-HT2A receptors and facilitating cognitive flexibility. Nonetheless, in the absence of robust, quantitative and...
