A 29-year-old male patient was treated and followed up for a pulmonary embolism. The patient had no relevant medical history, other than the fact that he had smoked bonzai, a synthetic cannabinoid derivative, for 2 years. Hypercoagulability tests were normal. The use of synthetic cannabinoids is increasing in the young population and should be kept in mind among the causes of pulmonary embolism.

Recent studies suggested the expression of CB2 receptors in neurons of the CNS, however, most of these studies have only explored one aspect of the receptors, i.e., expression of protein, messenger RNA, or functional response, and more complete studies appear to be needed to establish adequately their role in the neuronal function. Electron microscopy studies showed the presence of CB2r in asymmetric terminals of the substantia nigra pars reticulata (SNr), and its mRNA appears is expressed in the subthalamic nucleus...

The term schizophrenia describes a group of multifaceted psychiatric conditions causing significant impairment of the quality of life of affected patients. Although multiple pharmacological treatment options exist, e.g. first- or second-generation antipsychotics, these therapeutics often cause disturbing side effects, such as extrapyramidal symptoms, prolactin increase, sexual dysfunction and/or metabolic syndrome. Furthermore, cognitive impairments and negative symptoms, two factors significantly influencing the course and outcome, are not sufficiently addressed by the available antipsychotics...

Growing evidence supports the pivotal role played by oxidative stress in tissue injury development, thus resulting in several pathologies including cardiovascular, renal, neuropsychiatric, and neurodegenerative disorders, all characterized by an altered oxidative status. Reactive oxygen and nitrogen species and lipid peroxidation-derived reactive aldehydes including acrolein, malondialdehyde, and 4-hydroxy-2-nonenal, among others, are the main responsible for cellular and tissue damages occurring in redox-dependent processes...

G-protein-coupled receptors (GPCRs) control vital cellular signaling pathways. GPCR oligomerization is proposed to increase signaling diversity. However, many reports have arrived at disparate conclusions regarding the existence, stability, and stoichiometry of GPCR oligomers, partly because of cellular complexity and ensemble averaging of intrareconstitution heterogeneities that complicate the interpretation of oligomerization data. To overcome these limitations, we exploited fluorescence-microscopy-based high-content analysis of single proteoliposomes...

Cannabis has been widely used for various medical purposes since before year 2000 BC. Its effects are mediated by cannabinoids and stimulation of mainly G-protein coupled cannabinoid receptors. In 1971, subjects who smoked marihuana, showed a decrease in the intraocular pressure. Later investigations additionally revealed a neuroprotective effect of both ∆-9-tetrahydrocannabinol and cannabidiol (CBD). Furthermore, CBD was found to promote neurogenesis. The aim of this review is to provide an overview of the potential use of cannabinoids in the treatment of glaucoma...

The endocannabinoid system has emerged as a considerable target for the treatment of diverse diseases. In addition to the well-established palliative effects of cannabinoids in cancer therapy, phytocannabinoids, synthetic cannabinoid compounds as well as inhibitors of endocannabinoid degradation have attracted attention as possible systemic anticancer drugs. As a matter of fact, accumulating data from preclinical studies suggest cannabinoids elicit effects on different levels of cancer progression, comprising inhibition of proliferation, neovascularisation, invasion and chemoresistance, induction of apoptosis and autophagy as well as enhancement of tumour immune surveillance...

Upon liver intoxication with malnutrition or high-fat diet feeding, fibrinogen is synthesized by hepatocytes and secreted into the blood in human and mouse. Its primary function is to occlude blood vessels upon damage and thereby stop excessive bleeding. High fibrinogen levels may contribute to the development of pathological thrombosis, which is one mechanism linking fatty liver disease with cardiovascular disease. Our previous results present ERRγ as key regulator of hepatocytic fibrinogen gene expression in human...

Neuropathic pain typically appears in a region innervated by an injured or diseased nerve and, in some instances, also on the contralateral side. This so-called mirror image pain is often observed in mice lacking CB2 receptors after sciatic nerve injury, but the underlying mechanisms for this phenotype largely remain unclear. Here we focused on peripheral leptin signaling, which modulates neuropathic pain development and interacts with the endocannabinoid system. Leptin production is induced at the site of nerve injury in CB2-deficient mice (CB2-KO) mice and wild type controls (WT)...

In this study, the role of orexin-2 (OX2) and cannabinoid-1 (CB1) receptors and their potential interaction within the ventral tegmental area (VTA) on nicotine-induced place preference, was examined in male rats. A 5-day conditioned place preference (CPP) paradigm was used. Nicotine (0.5 mg/kg; s.c.) induced a significant CPP, without any effect on the locomotor activity during the testing phase. TCS-OX2-29 (0.4, 0.8 and 4 μg/rat), as a selective OX2 receptor antagonist and AM251 (0.2, 1 and 2 μg/rat), as a selective cannabinoid CB1 receptor antagonist, individually or simultaneously were microinjected bilaterally into the VTA...

Since the first detection of synthetic cannabinoids (SCs) in so-called 'legal high' products (e.g. 'Spice') sold as legal alternatives to marihuana, the rapid development of this class of designer drugs poses a great challenge for analytical laboratories. The aim of this study was the comprehensive validation of an up-to-date LC-MS/MS method for detection of SCs in human hair for the purpose of drug abstinence testing and evaluation of a pragmatic re-validation approach for frequent method adaption. The validation demonstrated low quantification limits (0...

Introduction: Legal access to marijuana, most frequently as "medical marijuana," is becoming more common in the United States, but most states do not specify sickle cell disease as a qualifying condition. We were aware that some of our patients living with sickle cell disease used illicit marijuana, and we sought more information about this. Materials and Methods: We practice at an urban, academic medical center and provide primary, secondary, and tertiary care for ∼130 adults living with sickle cell disease...

Earlier studies have shown that combination of antibodies to S100 protein and to cannabinoid receptor type 1 in released-active form (Brizantin) may possess anxiolytic properties and decrease nicotine dependence. Released-active form of antibodies is a novel approach that permits to modify natural functions of the target molecule (antigen) under investigation. The aim of the present study was to evaluate the anxiolytic-like effect of Brizantin in the light-dark test in mice, according to its ability to influence the number of entries into the lit compartment and the total time spent there...

The growing therapeutic use (self-medication) of cannabinoids by HIV-1 infected people and the recent interest in the possible medicinal use of cannabinoids, particularly in pain management, create an urgent need to identify their potential interactions with HIV-1. The goal here is to determine any interaction between proteins of HIV-1 and the analgesic effectiveness of cannabinoid at supraspinal level. Young adult male rats (Sprague-Dawley) were stereotaxically pretreated with HIV-1 envelope glycoprotein 120 (gp120) into the periaqueductal gray (PAG) area, the primary control center of pain modulation...

Studies have emphasized an antineoplastic effect of the non-psychoactive, phyto-cannabinoid, Cannabidiol (CBD). However, the molecular mechanism underlying its antitumor activity is not fully elucidated. Herein, we have examined the effect of CBD on two different human breast cancer cell lines: the ER-positive, well differentiated, T-47D and the triple negative, poor differentiated, MDA-MB-231 cells. In both cell lines, CBD inhibited cell survival and induced apoptosis in a dose dependent manner as observed by MTT assay, morphological changes, DNA fragmentation and ELISA apoptosis assay...
