Arndt and Harriet de Wit Cannabis and Cannabinoid Research, 2017, 2, (1), 105-113 DOI: 10.1089/can.2017.0014 Abstract Introduction : Cannabidiol (CBD) is a nonpsychoactive constituent of whole plant cannabis that has been reported to reduce anxiety-like behaviors in both pre-clinical and human laboratory studies. Yet, no controlled clinical studies have demonstrated its ability to reduce negative mood or dampen responses to negative emotional stimuli in humans. The objective of this study was to investigate the effects of CBD on responses to negative emotional stimuli, as a model for its potential anxiety-reducing effects. Materials and [...]

Aurélien Bernard NEWSWEED, Cannabis en France 18 juillet 2019 Une question nous est revenue à plusieurs reprises suite au récapitulatif du colloque sur le chanvre bien-être : pourquoi parler de « chanvre bien-être » ? Si l’on peut effectivement s’interroger sur la nécessité d’avoir toutes ces dénominations, elles servent pourtant à dissocier à la fois les usages et l’aspect réglementaire franco-français du cannabis. Nous avons donc : du chanvre industriel : variétés de cannabis à -0,2% de THC, pour un usage fibres et graines du chanvre bien-être : variétés de cannabis à -0,2% de [...]

Abstract Visual attention of adolescents with autism spectrum disorder (ASD) was assessed using a change blind-ness paradigm. Twenty-five adolescents with ASD aged 12–18 years and 25 matched typically developing (TD) adolescents viewed 36 pairs of digitized real-world images. Each pair of images was displayed in a ‘flicker paradigm’ whereby a particular item alternately appeared and disappeared. This item was either a central or a marginal [...]

Using anexperimental model of brain iron accumulation, we have shown that iron induces severe memory deficits thatare accompanied by oxidative stress, increased apoptotic markers, and decreased [...]
