AI Article Synopsis
- CBD is a substance from the cannabis plant that has antioxidant and anti-inflammatory benefits.
- This study tested the effects of CBD on zebrafish embryos and found it can harm their hearts and eyes, as well as cause liver issues.
- The research helps understand the risks of CBD before it can be used safely in medicine.
Article Abstract
Cannabidiol (CBD) is the main component of plant Cannabis (Cannabis sativa), which exhibits strong antioxidant and anti-inflammatory activities. With the legalization of CBD in the United States, it is an inevitable tendency for its global legalization in the future. Therefore, it has become an urgent task to conduct the toxicological evaluation of CBD before clinical application. In this study, the developmental toxicities of CBD on zebrafish embryos were systematically evaluated, and the mechanisms were revealed. The results showed that the phenotype of liver degeneration was observed in 96 hpf zebrafish embryos after 0.1-5 μmol/L CBD exposure, further RT-qPCR experiments indicated that the above result may attributed by the alterations of FABP10A, GCLC, and GSR. Besides, 1 and 5 μmol/L CBD contributed to the developmental toxicities of heart and eye in zebrafish embryos, characterizing by the decrease in heart rate, the phenotype of pericardial edema, and the reduce of eye area. Compared to other organs, the liver of zebrafish displayed the most sensitive characteristic to CBD exposure, as 0.1 μmol/L CBD already led to the phenotype of liver degeneration. In summary, this paper provided theoretical supports for CBD toxicology research, and laid the foundation for its future clinical application.

Objective: Identifying factors influencing cannabidiol (CBD) exposure can optimize treatment efficacy and safety. We aimed to describe the population pharmacokinetics of CBD in children with drug-resistant developmental and epileptic encephalopathies (DEEs) and assess the influence of environmental, pharmacological, and clinical characteristics on CBD systemic exposure.
Methods: Data from two pharmacokinetic studies of patients aged 2-18 years with DEEs were included (N = 48 patients).

Cannabis derivatives are among the most widely used psychoactive substances in the world, which leads to growing medical concerns regarding its chronic use and abuse especially among adolescents. Exposure to THC during formative years produces long-term behavioral alterations that share similarities with symptoms of psychiatric and neurodevelopmental disorders. In this study, we have analyzed the functional and molecular mechanisms that might underlie these alterations.

Ebola virus (EBOV) causes severe disease in humans, with mortality as high as 90%. The small-molecule antiviral drug remdesivir (RDV) has demonstrated a survival benefit in EBOV-exposed rhesus macaques. Here, we characterize the efficacy of multiple intravenous RDV dosing regimens on survival of rhesus macaques 42 days after intramuscular EBOV exposure.

Morphine is a commonly prescribed opioid analgesic used to treat chronic pain. Morphine undergoes glucuronidation by UDP-glucuronosyltransferase (UGT) 2B7 to form morphine-3-glucuronide and morphine-6-glucuronide. Morphine is the gold standard for chronic pain management and has a narrow therapeutic index.
