Cannabidiol (Cbd) And Resistance Training: Does Cbd Attenuate Acute Pain?, Guillermo Pacheco May 2024

Cannabidiol (Cbd) And Resistance Training: Does Cbd Attenuate Acute Pain?, Guillermo Pacheco

Masters Theses & Specialist Projects

INTRODUCTION: Resistance training (RT) is an advantageous form of physical activity for health and performance benefits; these benefits are maximized when done strenuously. However, strenuous RT can induce acute inflammatory pain which can lead to delayed-onset muscle soreness (DOMS). Common analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) can block protein synthesis, so other alternatives are needed for exercise and athletic communities to maintain physiological adaptations. Cannabidiol (CBD) is a non-psychotropic cannabinoid with purported anti-inflammatory, anti-oxidative, and analgesic properties. One of the main reasons for the use of CBD in exercise is pain alleviation; however, research in humans is limited. Therefore, the …


Cannabidiol Exposure During Rat Pregnancy Leads To Labyrinth-Specific Vascular Defects In The Placenta And Reduced Fetal Growth, Daniel B. Hardy, David R C Natale, Kendrick Lee Feb 2024

Cannabidiol Exposure During Rat Pregnancy Leads To Labyrinth-Specific Vascular Defects In The Placenta And Reduced Fetal Growth, Daniel B. Hardy, David R C Natale, Kendrick Lee

Physiology and Pharmacology Publications

Introduction: Cannabis use is increasing among pregnant people, and cannabidiol (CBD), a constituent of cannabis, is often perceived as ‘‘natural’’ and ‘‘safe’’ as it is non-intoxicating. In utero, cannabis exposure is associated with negative health outcomes, including fetal growth restriction (FGR). The placenta supplies oxygen and nutrients to the fetus, and alterations in placental development can lead to FGR. While there has been some investigation into the effects of D9-THC, there has been limited investigation into the impacts of in utero gestational CBD exposure on the placenta. Methods: This study used histological and transcriptomic analysis of embryonic day (E)19.5 rat …

Share Cannabidiol Exposure During Gestation Leads To Adverse Cardiac Outcomes Early In Postnatal Life In Male Rat Offspring., Daniel B. Hardy, Steven R. Laviolette, Kendrick Lee, David Rc Natale

Physiology and Pharmacology Publications

Introduction: Studies indicate that *7% of pregnant individuals in North America consume cannabis in pregnancy. Pre-clinical studies have established that maternal exposure to D9-tetrahydrocannabinol (THC; major psychoactive component in cannabis) leads to fetal growth restriction and impaired cardiac function in offspring. However, the effects of maternal exposure to cannabidiol (CBD; major non-euphoric constituent) on cardiac outcomes in offspring remain unknown. Therefore, our objective is to investigate the functional and underlying molecular impacts in the hearts of offspring exposed to CBD in pregnancy. Methods: Pregnant Wistar rats were exposed to either 3 or 30mg/kg CBD or vehicle control i.p. daily from …


Iuphar Review- Preclinical Models Of Neuropathic Pain: Evaluating Multifunctional Properties Of Natural Cannabinoid Receptors Ligands, Khalid Benamar Jan 2024

Iuphar Review- Preclinical Models Of Neuropathic Pain: Evaluating Multifunctional Properties Of Natural Cannabinoid Receptors Ligands, Khalid Benamar

School of Medicine Publications and Presentations

Neuropathic pain remains prevalent and challenging to manage and is often comorbid with depression and anxiety. The new approach that simultaneously targets neuropathic pain and the associated comorbidities, such as depression and anxiety, is timely and critical, given the high prevalence and severity of neuropathic pain and the lack of effective analgesics. In this review, we focus on the animal models of neuropathic pain that researchers have used to investigate the analgesic effects of cannabidiol (CBD) and Beta-Caryophyllene (BCP) individually and in combination while addressing the impact of these compounds on the major comorbidity (e.g., depression, anxiety) associated with neuropathic …

Center for Translational Medicine Faculty Papers

In recent years, there has been increased accessibility to cannabis for recreational and medicinal use. Incidentally, there has been an increase in reports describing allergic reactions to cannabis including exacerbation of underlying asthma. Recently, multiple protein allergens were discovered in cannabis, yet these fail to explain allergic sensitization in many patients, particularly urticaria and angioedema. Cannabis has a rich chemical profile including cannabinoids and terpenes that possess immunomodulatory potential. We examined whether major cannabinoids of cannabis such as cannabidiol (CBD) and the bicyclic sesquiterpene beta-caryophyllene (β-CP) act as contact sensitizers. The repeated topical application of mice skin with β-CP at …

The Polypharmacological Effects Of Cannabidiol, Jorge Castillo-Arellano, Ana Canseco-Alba, Stephen J. Cutler Ph.D., Francisco León Ph.D.

Faculty Publications

Cannabidiol (CBD) is a major phytocannabinoid present in Cannabis sativa (Linneo, 1753). This naturally occurring secondary metabolite does not induce intoxication or exhibit the characteristic profile of drugs of abuse from cannabis like Δ9-tetrahydrocannabinol (∆9-THC) does. In contrast to ∆9-THC, our knowledge of the neuro-molecular mechanisms of CBD is limited, and its pharmacology, which appears to be complex, has not yet been fully elucidated. The study of the pharmacological effects of CBD has grown exponentially in recent years, making it necessary to generate frequently updated reports on this important metabolite. In this article, a …

Cannabis, Cannabidiol, Cannabinoids, And Multigenerational Policy, Albert S. Reece, Gary Kenneth Hulse, Wei Wang

Research outputs 2022 to 2026

While classical laboratory and animal data have long established cannabinoid genotoxicity, it is only recently, with the application of modern analytical techniques, that the scale of epidemiological disease that may be attributable to cannabinoid exposure has been revealed. The importance and urgency of this work is heightened by the increased cannabis use that is accompanying the relaxation of legislation around cannabis use in many places, the widespread global movement toward cannabis legalization, and the general increase in the cannabinoid potency of available strains. . .

Sedation And Acute Encephalopathy In A Pediatric Patient Following Ingestion Of Delta-8-Tetrahydrocannabinol Gummies, Peter Akpunonu, Regan A. Baum, Andrew Reckers, Blake Davidson, Ross Ellison, Matthew Riley, Jordan Trecki, Roy Gerona

Emergency Medicine Faculty Publications

BACKGROUND Delta-8 tetrahydrocannabinol (delta-8 THC) is an isomer of delta-9-tetrahydrocannabinol (delta-9 THC), the primary psychoactive cannabinoid in the marijuana plant. Typically found at lower concentrations in marijuana, delta-8 THC exhibits psychoactive properties similar to delta-9 THC. Products containing delta-8 THC are readily available across the US and currently there is a lack of available confirmatory testing specific to delta-8 THC as there is cross-reactivity to other naturally occurring cannabinoids in standard immunoassays. Pediatric exposures to this substance are on the rise.

CASE REPORT We present a case with laboratory confirmation of a previously healthy 2-year-old girl ingesting approximately 15 mg/kg …

Impacts Of Cannabinoid Epigenetics On Human Development: Reflections On Murphy Et. Al. 'Cannabinoid Exposure And Altered Dna Methylation In Rat And Human Sperm' Epigenetics 2018; 13: 1208-1221, Albert Stuart Reece, Gary Kenneth Hulse

Research outputs 2014 to 2021

Recent data from the Kollins lab ('Cannabinoid exposure and altered DNA methylation in rat and human sperm' Epigenetics 2018; 13: 1208-1221) indicated epigenetic effects of cannabis use on sperm in man parallel those in rats and showed substantial shifts in both hypo- and hyper-DNA methylation with the latter predominating. This provides one likely mechanism for the transgenerational transmission of epigenomic instability with sperm as the vector. It therefore contributes important pathophysiological insights into the probable mechanisms underlying the epidemiology of prenatal cannabis exposure potentially explaining diverse features of cannabis-related teratology including effects on the neuraxis, cardiovasculature, immune stimulation, secondary genomic …

Mutations in the Fragile X Mental Retardation 1 (FMR1) gene create a spectrum of developmental disorders in children in addition to neurodegenerative problems in older populations. Two types of mutations are recognized in the FMR1 gene. The full mutation (>200 CGG repeats) in the FMR1 gene leads to Fragile X Syndrome which is the most common inherited cause of intellectual disability and autism, while the premutation (55 to 200 CGG repeats) identified among carriers leads to a range of problems linked to elevated levels of the FMR1 mRNA leading to mRNA toxicity and occasionally mildly deficient FMRP …

Ateneo School of Medicine and Public Health Publications

Fragile X Syndrome (FXS) is the most common cause of inherited intellectual disability with prevalence rates estimated to be 1:5,000 in males and 1:8,000 in females. The increase of >200 Cytosine Guanine Guanine (CGG) repeats in the 5' untranslated region of the Fragile X Mental Retardation 1 (FMR1) gene results in transcriptional silencing on the FMR1 gene with a subsequent reduction or absence of fragile X mental retardation protein (FMRP), an RNA binding protein involved in the maturation and elimination of synapses. In addition to intellectual disability, common features of FXS are behavioral problems, autism, language deficits and atypical physical …

Are There Mortality Risks For Patients With Epilepsy Who Use Cannabis Treatments As Monotherapy?, Devon M Kollmyer, Kyla E Wright, Nicole M Warner, Michael J Doherty Jan 2019

Are There Mortality Risks For Patients With Epilepsy Who Use Cannabis Treatments As Monotherapy?, Devon M Kollmyer, Kyla E Wright, Nicole M Warner, Michael J Doherty

Articles, Abstracts, and Reports

Mortality associated with cannabis used for treatment of epilepsy is not well documented. We discuss two fatalities in the setting of epilepsy and self-determined therapy with cannabis (SDTC). One patient had probable sudden unexpected death in epilepsy, the second death was due to seizure-associated drowning. Both directed SDTC over conventional anti-seizure medications. Where recreational cannabis is legal, decisions to use cannabis are often self-directed and independent of physician advice of cannabis risks, in part because physicians may not be aware of the risk of SDTC. Further study of morbidity and mortality of SDTC in patients with epilepsy is needed.
