Neuroprotection by cannabidiol and hypothermia in a piglet model of newborn hypoxic-ischemic brain damage Lorena Barataa, Luis Arruza, Maria-José Rodríguez, Esther Aleo, Eva Vierge, Enrique Criado, Elena Sobrino, Carlos Vargas, María Ceprián, Ana Gutiérrez-Rodríguez, William Hind, José Martínez-Orgado Neuropharmacology, 2018. https://doi.org/10.1016/j.neuropharm.2018.11.020 A B S T R A C T Objective : Hypothermia, the gold standard after a hypoxic-ischemic insult, is not beneficial in all treated newborns. Cannabidiol is neuroprotective in animal models of newborn hypoxic-ischemic encephalopathy. This study compared the relative efficacies of cannabidiol and hypothermia in newborn hypoxic-ischemic piglets and assessed whether addition of cannabidiol augments hypothermic neuroprotection. Methods : One day-old HI (carotid clamp and FiO2 10% for 20min) [...]
Lire la suiteREVIEW : Cannabidiol – Recent Advances Raphael Mechoulam, Maximilian Petersa, Eric Murillo-Rodriguez and Lumïr O. Hanus Chemistry and Biodiversity, 2007, 4, 1678-1692. The aim of this review is to present some of the recent publications on cannabidiol (CBD; 2), a major non-psychoactive constituent of Cannabis, and to give a general overview. Special emphasis is laid on biochemical and pharmacological advances, and on novel mechanisms recently put forward, to shed light on some of the pharmacological effects that can possibly be rationalized through these mechanisms. The plethora of positive pharmacological effects observed with CBD make this compound a highly attractive therapeutic entity. Contents 1. Introduction 2. Mechanisms of Cannabidiol Action 2.1. Cannabidiol: an [...]

Patricia Schonhofen, Ivi Juliana Bristot, José Alexandre Crippa, Jaime Eduardo Cecilio Hallak, Antonio Waldo Zuardi, Richard B. Parsons, Fabio Klamt CNS Drugs, 2018, 32 (Suppl 1), 1-16 https///doi.org/10.1007/s40263-018-0550-4 Abstract : The endocannabinoid retrograde signaling pathway is widely expressed in the central nervous system, where it plays major roles in regulating synaptic plasticity (excitatory and inhibitory) through long-term potentiation and long-term depression. The endocannabinoid system (ECS) components-cannabinoid receptors, endocannabinoids and synthesis/degradation enzymes-are expressed and are functional from early developmental stages and throughout adolescent cortical development, regulating progenitor cell fate, neural [...]

DOI : 10.1523/JNEUROSCI.2946-14.2015 Abstract : Recent research has suggested that marijuana use is associated with volumetric and shape differences in subcortical structures, including the nucleus accumbens and amygdala, in a dose-dependent fashion. Replication of such results in well controlled [...]

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 [...]

Journal of Neurotrauma, Nov 2018, 36, 1-11 DOI: 10.1089/neu.2018.6063 Abstract : Cannabis is one of the most widely used plant drugs in the world today. In spite of the large number of scientific reports on medical marijuana, there still exists much controversy surrounding its use and the potential for abuse due to the undesirable psychotropic effects. However, recent developments in medicinal chemistry of novel non-psychoactive synthetic cannabinoids have indicated that it is possible to separate some of the therapeutic effects [...]

Apart from updating the literature, this article focuses on clinical studies and CBD potential interactions with other drugs. Results: In general, the often described favorable safety profile of CBD in humans was confirmed and extended by the reviewed research. The majority of studies were performed for treatment of epilepsy [...]

Et pourtant, bien des « méta-analystes » qui parfois, n’ont jamais vu un patient, sans vergogne, « disent le vrai », et emportent l’opinion avec eux, opinion et journalistes qui se font l’écho de ses assertions, sans même émettre la moindre critique vis-à-vis de ces « chiffres » érigés en « [...]
