Abstract : In spite of new drugs, lung cancer is associated with a very poor prognosis. While targeted therapies are improving outcomes, it is not uncommon for many patients to have only a partial response, and relapse during follow-up. Thus, new drugs or reevaluation of existing therapies used to treat other non-malignant diseases (drug repurposing) are still needed. While this research both in vitro and in vivo is being carried [...]

The types of drugs discussed in this context focus on those assumed to be the most ‘addictive’ – heroin and cocaine – to those less well-known but potentially more hazardous to use without [...]

Results from a canonical correlation analysis indicated that obsessive passion scores were significantly positively associated with past 30-day consumption, [...]

One is that cannabis use by young adults and vulnerable individuals across the lifespan can be a contributory cause of : a cannabis dependence syndrome; schizophreniform psychoses; anxiety and depressive disorders; acute and perhaps chronic cognitive impairment, and structural and functional changes in brain pathways implicated in reward, learning and [...]
Lire la suiteCultural Neurophenomenology of Psychedelic Thought: Guiding the “Unconstrained” Mind Through Ritual Context Michael LIFSHITZ, Eli SHEINER, and Laurence J. KIRMAYER The Oxford Handbook of Spontaneous Thought : Mind-Wandering, Creativity, and Dreaming Edited by Kalina Christoff and Kieran C.R. Fox, avril 2018 Abstract : This chapter explores psychedelics as catalysts of spontaneous thought. Classic serotonergic psychedelics such as psilocybin, LSD, and ayahuasca can induce potent alterations in cognition and perception. The chapter reviews research on these substances through the lens of cultural neurophenomenology, which aims to trace how neurobiology and sociocultural factors interact to shape experience. After a decades-long hiatus, the scientific study of psychedelics is rediscovering [...]
