Comparison of State-Level Regulations for Cannabis Contaminants and Implications for Public Health.

Background: The presence of contaminants in cannabis presents a potential health hazard to recreational users and susceptible patients with medical conditions. Because of the federally illegal status of cannabis, there are no unified regulatory guidelines mitigating the public health risk of cannabis contaminants.

Objective: To inform further research and provide solutions to the public health risk of cannabis contaminants at a national level, we examined the current landscape of state-level contaminant regulations, and cannabis contaminants of concern, as well as patient populations susceptible to contaminants.

Neurotoxicity Testing: Novel Applications in the Adverse Outcome Pathway Framework.

Neurological hazard assessment of industrial and pesticidal chemicals demands a substantial amount of time and resources. is an established model organism in developmental biology and neuroscience. It presents an ideal test system with relatively fewer neurons (302 in hermaphrodites) versus higher-order species, a transparent body, short lifespan, making it easier to perform neurotoxic assessment in a time and cost-effective manner.

Regulatory Status of Pesticide Residues in Cannabis: Implications to Medical Use in Neurological Diseases.

Medical cannabis represents a potential route of pesticide exposure to susceptible populations. We compared the qualifying conditions for medical use and pesticide testing requirements of cannabis in 33 states and Washington, D.C.

The Nesprin-1/-2 ortholog ANC-1 regulates organelle positioning in independently from its KASH or actin-binding domains.

KASH proteins in the outer nuclear membrane comprise the cytoplasmic half of linker of nucleoskeleton and cytoskeleton (LINC) complexes that connect nuclei to the cytoskeleton. ANC-1, an ortholog of Nesprin-1/2, contains actin-binding and KASH domains at opposite ends of a long spectrin-like region. Deletion of either the KASH or calponin homology (CH) domains does not completely disrupt nuclear positioning, suggesting neither KASH nor CH domains are essential.

Xenobiotic metabolism and transport in .

has emerged as a major model in biomedical and environmental toxicology. Numerous papers on toxicology and pharmacology in have been published, and this species has now been adopted by investigators in academic toxicology, pharmacology, and drug discovery labs. has also attracted the interest of governmental regulatory agencies charged with evaluating the safety of chemicals.
