Article Title: Design and function of targeted endocannabinoid nanoparticles
Article Snippet: Synthetic standards of PEA, OEA, LEA and d4-AEA (Cayman Chemical, Ann Arbor, MI, USA) were used to generate calibration curves for quantification by LabSolutions software (Shimadzu, Rydalmere, NSW, Australia).

Article Title: Endocannabinoids regulate cocaine-associated memory through brain AEA–CB1R signalling activation
Article Snippet: Tissues were spiked with ethyl acetate/hexane and internal standards (d4-AEA (10011178, Cayman) at 10 μg/mL; d5-2-AG (362,162, Cayman) at 100 μg/mL; 2 μL of mixed internal standards for each sample) and ultrasonicated in an ice-cold water bath.

Article Title: Stable isotope liquid chromatography-tandem mass spectrometry assay for fatty acid amide hydrolase activity.
Article Snippet: Fatty acid amide hydrolase (FAAH) is the main enzyme responsible for the hydrolysis of the endocannabinoid anandamide (arachidonoyl ethanolamide, AEA) to arachidonic acid (AA) and ethanolamine (EA).. Published FAAH activity assays mostly employ radiolabeled anandamide or synthetic fluorogenic substrates.. We report a stable isotope liquid chromatography–tandem mass spectrometry (LC–MS/MS) assay for specific, sensitive, and high-throughput capable FAAH activity measurements.

Article Title: Investigation of changes in endocannabinoids and N-acylethanolamides in biofluids, and their correlations with female infertility.
Article Snippet: Female infertility is a worldwide medical problem, and the scarcity of infertility biomarkers has hindered the ability to launch preventive and therapeutic measures in a timely manner.. Intriguingly, alterations in endocannabinoids (eCBs) and Nacylethanolamides (NAEs) have been observed in the biofluids of infertile females.. Therefore, a hypothesis of using eCB and NAEs in biofluids as infertility biomarkers was proposed by several researchers; however, little evidence exists to verify the hypothesis.

Article Title: Peripheral endocannabinoid microdialysis: in vitro characterization and proof-of-concept in human subjects
Article Snippet: In vivo endocannabinoid (EC) microdialysis has only seldom been performed, mostly in rodent brain tissue.. Low solubility in aqueous media, adsorption to surfaces, and instability with co-present human serum albumin (HSA) are the major obstacles in EC microdialysis.. The addition of hydroxypropyl-ß-cyclodextrine (HPCD) to the perfusion fluid has been previously described to facilitate lipid microdialysis, but the general biophysical properties of HPCD, especially with respect to peripheral EC microdialysis, have not been described before.

Article Title: LC-MS/MS Analysis of the Epoxides and Diols Derived from the Endocannabinoid Arachidonoyl Ethanolamide
Article Snippet: Alternatively, the d4-AEA (Cayman Chemical, Ann Arbor, MI, USA) can be used as an internal standard for extracting EET-EAs and DHET-EAs, especially if there are levels of endogenous AEA in the tissue samples.

Article Snippet: .. Each sample was diluted 1∶1 with methanol containing the internal standard d4-AEA (arachidonoyl-ethanolamide) labeled with 4 deuterium atoms replacing the 4 H's on the methylenes of ethanolamine moiety, Cayman Chemical, Ann Arbor, MI) Waters Acquity/TQD system in positive ion (ES+) mode. ..
