Although the underlying mechanism remains unknown, several studies have suggested benefits of n-3 long-chain polyunsaturated fatty acid (PUFA) for patients with anxiety disorders. Elevated fear is thought to contribute to the pathogenesis of particular anxiety disorders. The aim of the present study
Memory and GABAergic activity in the hippocampus of stressed rats improve after n-3 polyunsaturated fatty acid (PUFA) supplementation. On the other hand, cannabinoid receptor type 1 (CB1) strongly regulates inhibitory neurotransmission in the hippocampus. Speculation about a possible
Sleep deprivation (SD) is a common feature in modern society. Prolonged sleep deprivation causes cognition deficits and depression-like behavior in the model of animal experiments. Endocannabinoid system are key modulators of synaptic function, which were related to memory and mood. Although the
The seed of the hemp plant (Cannabis sativa L.) has been revered as a nutritional resource in Old World Cultures. This has been confirmed by contemporary science wherein hempseed oil (HSO) was found to exhibit a desirable ratio of omega-6 and omega-3 polyunsaturated fatty acids (PUFAs) considered
N-3 polyunsaturated fatty acids (PUFAs) cannot be synthesized de novo in mammals and need to be provided by dietary means. In the brain, the main n-3 PUFA is docosahexaenoic acid (DHA), which is a key component of neuronal membranes. A low dietary level of DHA has been associated with increased risk
12-Phenylacetyl-ricinoleoyl-vanillamide (phenylacetylrinvanil, PhAR, IDN5890), is an ultra-potent agonist of human vanilloid TRPV1 receptors also endowed with moderate affinity for human cannabinoid CB(2) receptors. To improve its CB(2) affinity and temper its potency at TRPV1, the modification of
OBJECTIVE
An 18-year-old man with Arnold-Chiari malformation (ACM) type I developed sudden panic attacks. He also manifested sleep disorder, cannabis abuse, and psychosis-risk syndrome (PRS). Although with average-superior intelligence, he had executive dysfunction. This prompted us to explore the
Anandamide (AEA) is an endogenous agonist for the cannabinoid receptor 2 (CB2) which is expressed in osteoblasts. Arachidonic acid (AA) is the precursor for AEA and dietary n-3 polyunsaturated fatty acids (PUFA) are known to reduce the concentrations of AA in tissues and cells. Therefore, we
Various purified lipoxygenases were incubated with [14C]arachidonylethanolamide which is an endogenous ligand for cannabinoid receptors. When radioactive products were analyzed by thin-layer chromatography, porcine leukocyte 12-lipoxygenase and rabbit reticulocyte and soybean 15-lipoxygenases
In this study, eight cultivars of hempseed were collected from different regions of China for analysis of physiochemical properties and chemical composition, as well as for seed indexes and proximate composition of seed kernel. The results indicated that Yunma No. 1 and Bama Huoma, with more than
Cyclooxygenase (COX) possesses substrate affinity for the endocannabinoids (EC) anandamide (AEA) and 2-arachidonylglycerol (2-AG). We hypothesized that selective antagonism/activation of the cannabinoid receptors will increase COX activity and the availability of EC as substrates will lead to higher
Considering the increase in consumption of Cannabis sativa and the use of the compound β-carotene (BC) as supplement, we investigated potential changes in the chemical and biological proprieties of BC after exposure to C. sativa smoke (CSS). Our results showed that the BC exposed to CSS underwent
Delta(9)-Tetrahydrocannabinol (Delta(9)-THC) is the major psychoactive component of marijuana and elicits pharmacological actions via cannabinoid receptors. Anandamide (AEA) and 2-arachidonoyl-glycerol (2-AG) are endogenous ligands for cannabinoid receptors, which because of their structural
Hemp seed oil is well known for its nutraceutical, cosmetic and pharmaceutical properties due to a perfectly balanced content of omega 3 and omega 6 polyunsaturated fatty acids. Its importance for human health is reflected by the success on the market of organic goods in recent years. However, it is
Cannabinoid type 1 receptors and transient receptor potential vanilloid type 1 channels have been proposed to act as metabotropic and ionotropic receptors, respectively, for two classes of endogenous polyunsaturated fatty acid amides, the acylethanolamides and the acyldopamides. Furthermore, we and
