Rationale for cannabis-based interventions in the opioid overdose crisis, Philippe Lucas, 2017

Rationale for cannabis-based interventions in the opioid overdose crisis Philippe Lucas Harm Reduction Journal, 2017, 14, 58 Doi : 10.1186/s12954-017-0183-9   Abstract Background : North America is currently in the grips of a crisis rooted in the use of licit and illicit opioid-based analgesics. Drug overdose is the leading cause of accidental death in Canada and the US, and the growing toll of opioid-related morbidity and mortality requires a diversity of novel therapeutic and harm reduction-based interventions. Research suggests that increasing adult access to both medical and recreational cannabis has significant positive impacts on public health and safety as a result of substitution effect. Observational and [...]

Potential combinations of endocannabinoid/endocannabinoid-like compounds and antibiotics against methicillin-resistant Staphylococcus aureus, Mark Feldman et al., 2020

Potential combinations of endocannabinoid/endocannabinoid-like compounds and antibiotics against methicillin-resistant Staphylococcus aureus Mark Feldman, Reem Smoum, Raphael Mechoulam, Doron Steinberg PLoS One, April 15, 2020, 1-13. Doi : 10.1371/journal.pone.0231583   Abstract Infections caused by antibiotic-resistant strains of Staphylococcus aureus have reached epidemic proportions globally. Our previous study showed antimicrobial effects of anandamide (AEA) and arachidonoyl serine (AraS) against methicillin (MET)-resistant S. aureus (MRSA) strains, proposing the therapeutic potential of these endocannabinoid/endocannabinoid-like (EC/EC-like) agents for the treatment of MRSA. Here, we investigated the potential synergism of combinations of AEA and AraS with different types of antibiotics against MRSA grown under planktonic growth or biofilm formation. The most effective [...]

Dynamic coupling of whole-brain neuronal and neurotransmitter systems, Morten L. Kringelbach et al., 2020

Dynamic coupling of whole-brain neuronal and neurotransmitter systems Morten L. Kringelbach, Josephine Cruzat, Joana Cabral, Gitte Moos Knudsen, Robin Carhart-Harris, Peter C. Whybrow Nikos K. Logothetis, and Gustavo Deco PNAS, 2020, 1-11 doi : 10.1073/pnas.1921475117   Remarkable progress has come from whole-brain models linking anatomy and function. Paradoxically, it is not clear how a neuronal dynamical system running in the fixed human anatomical connectome can give rise to the rich changes in the functional repertoire associated with human brain function, which is impossible to explain through long-term plasticity. Neuromodulation evolved to allow for such flexibility by dynamically updating the effectivity of the fixed anatomical connectivity. [...]

An epidemiological, developmental and clinical overview of cannabis use during pregnancy, Hanan El Marroun et al., 2018

An epidemiological, developmental and clinical overview of cannabis use during pregnancy Hanan El Marroun, Qiana L. Brown, Ingunn Olea Lund, Victoria H. Coleman-Cowger, Amy M. Loree, Devika Chawlaj, Yukiko Washio Preventive Medicine, 2018, 116, 1–5 Doi : 10.1016/j.ypmed.2018.08.036   A B S T R A C T The objective of the current narrative literature review is to provide an epidemiological, developmental and clinical overview on cannabis use during pregnancy. Cannabis use in pregnancy poses major health concerns for pregnant mothers and their developing children. Although studies on the short- and long-term consequences of prenatal cannabis exposure are increasing, findings have been inconsistent or difficult to interpret [...]

The Broad Concept of “Spasticity- Plus Syndrome” in Multiple Sclerosis : A Possible New Concept in the Management of Multiple Sclerosis Symptoms, Óscar Fernández et al., 2020

The Broad Concept of “Spasticity- Plus Syndrome” in Multiple Sclerosis : A Possible New Concept in the Management of Multiple Sclerosis Symptoms Óscar Fernández, Lucienne Costa-Frossard, Marisa Martínez-Ginés, Paloma Montero, José Maria Prieto and Lluis Ramió Frontiers in Neurology , 2020 | Volume 11 | Article 152 doi : 10.3389/fneur.2020.00152   Multiple sclerosis (MS) pathology progressively affects multiple central nervous system (CNS) areas. Due to this fact, MS produces a wide array of symptoms. Symptomatic therapy of one MS symptom can cause or worsen other unwanted symptoms (anticholinergics used for bladder dysfunction produce impairment of cognition, many MS drugs produce erectile dysfunction, etc.). Appropriate symptomatic [...]

Cannabinol inhibits proliferation and induces cell cycle arrest and apoptosis in glioblastoma, hepatocellular carcinoma and breast cancer cells, Nuanying Zhong, 2020

Cannabinol inhibits proliferation and induces cell cycle arrest and apoptosis in glioblastoma, hepatocellular carcinoma and breast cancer cells Nuanying ZHONG, Thesis, Master of Science in Biological Sciences Faculty of Arts and Science, Department of Biological Sciences, University of Lethbridge Research Repository, Canada 2020 https://hdl.handle.net/10133/5697   ABSTRACT Cannabis sativa is an agriculturally and medicinally plant with many pharmaceutical properties. Cancer is a deadly disease; it is estimated that it will cause over 80 thousand deaths in 2019 in Canada. Although numerous studies have demonstrated that cannabinoids have anti-tumorous properties in various cancers, the anti-malignant activities of cannabinol (CBN) on carcinogenesis and underlying mechanisms remain largely unknown. In this study, we [...]

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors, David B. Finlay et al., 2020

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors David B. Finlay, Kathleen J. Sircombe, Mhairi Nimick, Callum Jones and Michelle Glass Frontiers in Pharmacology, 2020, Volume 11, Article 359, 1-9. doi : 10.3389/fphar.2020.00359   The entourage effect was a proposed explanation for biological observations that endocannabinoid ligand activities can be modified by other lipids released from cells at the same time. An increasing volume of anecdotal reports and interest in the plant have provoked research into the activity of minor chemical constituents of the plant—including volatile terpenoids such as myrcene, a- and b- pinene, b-caryophyllene, and limonene. However, to [...]

High Times for Painful Blues : The Endocannabinoid System in Pain-Depression Comorbidity, Marie Fitzgibbon et al., 2016

High Times for Painful Blues : The Endocannabinoid System in Pain-Depression Comorbidity Marie Fitzgibbon, David P. Finn,  Michelle Roche International Journal of Neuropsychopharmacology, 2016, 19, (3), 1–20 doi : 10.1093/ijnp/pyv095   Abstract Depression and pain are two of the most debilitating disorders worldwide and have an estimate co-occurrence of up to 80%. Comorbidity of these disorders is more difficult to treat, associated with significant disability and impaired healthrelated quality of life than either condition alone, resulting in enormous social and economic cost. Several neural substrates have been identified as potential mediators in the association between depression and pain, including neuroanatomical reorganization, monoamine and neurotrophin depletion, dysregulation [...]
