According to the World Health Organization, the cases of death caused by cancer will have been doubled until the year 2030. By 2010, cancer is expected to be the number one cause of death. Therefore, it is necessary to explore novel approaches for the treatment of cancer. Over past years, the antitumorigenic effects of cannabinoids have emerged as an exciting field in cancer research. Apart fro...

objective(s):diabetic neuropathy (dn) is a common complication of diabetes that leads to allodynia, impaired nerve conduction, and progressive sensory loss. the aim of this study was to observe the effect of a high-affinity cannabinoid receptors agonist, win 55,212-2, on thermal hyperalgesia, nerve conduction velocity and sciatic nerve histopathology in diabetic rats. materials and methods: dia...

OBJECTIVE Patients with chronic pain, including fibromyalgia (FM), may seek treatments outside of mainstream medicine. Medicinal cannabinoids are popularly advocated for pain relief but with limited evidence for efficacy in FM. The extent of use of cannabinoids in FM is unknown. METHODS We have documented the self-reported prevalence of cannabinoid use in 457 patients with the diagnosis of FM...

BACKGROUND Synthetic cannabinoids are compounds that bind cannabinoid receptors with a high potency and have been used widely in Europe by young people. However, little is known about the pharmacology and morphological effects of this group of substances in the brain. This study is aimed at investigating the morphological differences among synthetic cannabinoids users and healthy controls. ME...

INTRODUCTION The use of synthetic drugs of abuse in the United States has grown in the last few years, with little information available on how much physicians know about these drugs and how they are treating patients using them. The objective of this study was to assess emergency physician (EP) knowledge of synthetic cannabinoids (SC). METHODS A self-administered internet-based survey of res...

Cannabinoids, the primary active agent in drugs of abuse such as marijuana and hashish, tend to generate a distorted sense of time. Here we study the effect of cannabinoids on the brain's circadian clock, the suprachiasmatic nucleus (SCN), using patch clamp and cell-attached electrophysiological recordings, RT-PCR, immunocytochemistry, and behavioral analysis. The SCN showed strong expression o...

The Microgenics CEDIA DAU (EIA) and the Abbott AxSym system (FPIA) cannabinoids assays were evaluated for their combined effectiveness in the analysis of cannabinoids in whole blood. Blood samples were treated with acetone, evaporated, and reconstituted, and the supernatant was analyzed by the EIA cannabinoids assay. Blood samples determined positive by EIA were then treated with acetonitrile a...

Cannabinoids are a group of compounds that mediate their effects through cannabinoid receptors. The discovery of Δ9-tetrahydrocannabinol (THC) as the major psychoactive principle in marijuana, as well as the identification of cannabinoid receptors and their endogenous ligands, has led to a significant growth in research aimed at understanding the physiological functions of cannabinoids. Cannabi...

At many central synapses, endocannabinoids released by postsynaptic cells act retrogradely on presynaptic G-protein-coupled cannabinoid receptors to inhibit neurotransmitter release. Here, we demonstrate that cannabinoids may directly affect the functioning of inhibitory glycine receptor (GlyR) channels. In isolated hippocampal pyramidal and Purkinje cerebellar neurons, endogenous cannabinoids ...
