Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

JSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

Effect of different light‐emitting diodes on vegetative cannabis growth and antioxidant activity

JSFA reports, EarlyView.
Abstract Background Cannabis stands as one of the world's oldest plant sources for food and textile fiber. The study aimed to assess the impact of white LED (blue; 446 nm + amber; 595 nm + red; 653 nm), wide PC amber (595 nm), narrow amber (595 nm) + royal blue (430 nm) (NA + RB), and narrow amber (595 nm) + royal blue (430 nm) + cyan blue (485 nm) (NA

Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Cannabinoid Hyperemesis [PDF]

Canadian Journal of Gastroenterology and Hepatology, 2009
Cannabinoid hyperemesis syndrome is characterized by chronic, heavy use of cannabis, recurrent episodes of severe nausea and intractable vomiting, and abdominal pain. Temporary relief of symptoms is achieved by taking a hot bath or shower, and resolution of the problem when cannabis use is stopped.

High Prevalence and Clinical Impact of Fibromyalgia in Functional Motor Disorder

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Fibromyalgia is characterized by widespread pain, fatigue, sleep and cognitive symptoms. It overlaps clinically with functional motor disorder (FMD), yet its prevalence and impact in FMD remain uncertain. Objective To determine the prevalence of fibromyalgia in FMD using the current criteria and evaluate its effects on motor ...

The Effect of Cannabidiol on Subjective Responses to Endurance Exercise: A Randomised Controlled Trial

Sports Medicine - Open
Background Exercise is known to improve health. However, it can be unpleasant, often inducing negative feelings, or ‘affect’. Cannabidiol (CBD), a non-intoxicating constituent of the cannabis plant, has been reported to enhance the subjective experience ...
