BACKGROUND: Exposure to beryllium may lead to granuloma formation and fibrosis in those who develop chronic beryllium disease (CBD). Although disease presentation varies from mild to severe, little is known about CBD phenotypes. This study characterized CBD disease phenotypes using longitudinal measures of lung function. METHODS: Using a case-only study of 207 CBD subjects, subject-specific trajectories over time were estimated from longitudinal pulmonary function and exercise-tolerance tests...

RATIONALE: Choledocholithiasis in common bile duct (CBD) stump after Roux-en-Y hepaticojejunostomy (RYHJ) is incredibly rare and its pathophysiology is poorly understood. PATIENT CONCERNS: A 79-year-old woman was admitted to our hospital with upper abdominal pain radiating through to the back in November 2016. DIAGNOSES: Abdominal computed tomography (CT) scan and magnetic resonance cholangiopancreatography (MRCP) revealed filling defects in CBD stump, chronic pancreatitis, and dilatation of CBD stump and main pancreatic duct (MPD)...

Lipid-lowering therapy with statins reduces the risk of cardiovascular events, but the efficacy of persistent treatment in a real-world setting may vary from regions. Routine lipid-lowering therapy in the region with a high prevalence of cardiovascular disease may lead to more failures of goal attainment. We therefore performed a study to observe different lipid-lowering strategies in northeast (NE) China with respect to low-density lipoprotein-cholesterol (LDL-C) reduction and goal attainments.A cross-sectional study (DYSIS-China) was conducted in 2012, involving 25,317 patients from 122 centers across China who were diagnosed with hyperlipidemia and treated with lipid-lowering therapy for at least 3 months...

Spasticity, perceived by patients as muscle rigidity and spasms, is a common symptom in multiple sclerosis (MS). It is associated with functional impairment that can exacerbate other MS symptoms and reduce quality of life. Pharmacological treatment options are limited and frequently ineffective. Treatment adherence is a key issue to address in these patients. The efficacy and safety of 9-delta-tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray for treatment of MS spasticity were demonstrated in four Phase III trials...

BACKGROUND: Congenital biliary dilatation (CBD) is a congenital malformation involving both dilatation of the extrahepatic bile duct and pancreaticobiliary maljunction. Persistent reflux of pancreatic juice injures the biliary tract mucosa, resulting in chronic inflammation and higher rates of carcinogenesis in the biliary tract, including the gallbladder. Telomeres are repetitive DNA sequences located at the ends of chromosomes. Chromosomal instability due to telomere dysfunction plays an important role in the carcinogenesis of many organs...

Background: Cellulose, the most abundant biopolymer on earth, is an alternative for fossil fuels as a renewable feedstock for the production of second-generation biofuels and other chemicals. The discovery of novel, highly efficient β-glucosidases remains as one of the major bottlenecks for cellulose degradation. In this context, the ascomycete Talaromyces amestolkiae, isolated from cereal samples, has been studied as a promising source for these enzymes. Results: BGL-2 is the major β-glucosidase secreted by this fungus in the presence of cellulosic inductors...

Metabolic and behavioural effects of, and interactions between Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are influenced by dose and administration route. Therefore we investigated, in Wistar rats, effects of pulmonary, oral and subcutaneous (sc.) THC, CBD and THC+CBD. Concentrations of THC, its metabolites 11-OH-THC and THC-COOH, and CBD in serum and brain were determined over 24h, locomotor activity (open field) and sensorimotor gating (prepulse inhibition, PPI) were also evaluated. In line with recent knowledge we expected metabolic and behavioural interactions between THC and CBD...

OBJECTIVE: The fitness to practise of international medical graduates (IMGs) is usually evaluated with standardised assessment tests. The performance rather than the competency of practising doctors should, however, be assessed, for which reason workplace-based assessment (WBA) has gained increasing attention. Our aim was to assess the composite reliability of WBA instruments for assessing IMGs. DESIGN AND SETTING: Between June 2010 and April 2015, 142 IMGs were assessed by 99 calibrated assessors; each was assessed in the workplace over 6 months...

Major self-mutilation (amputation, castration, self-inflicted eye injuries) is frequently associated with psychiatric disorders and/or substance abuse. A 35-year-old man presented with behavioral disturbances of sudden onset after oral cannabis consumption and major self-mutilation (attempted amputation of the right arm, self-enucleation of both eyes and impalement) which resulted in death. During the enquiry, four fragments of a substance resembling cannabis resin were seized at the victim's home. Autopsy confirmed that death was related to hemorrhage following the mutilations...

Cannabidiol (CBD) is the main nonpsychoactive component of the cannabis plant. It has been associated with antiseizure, antioxidant, neuroprotective, anxiolytic, anti-inflammatory, antidepressant, and antipsychotic effects. PTL101 is an oral gelatin matrix pellets technology-based formulation containing highly purified CBD embedded in seamless gelatin matrix beadlets. Study objectives were to evaluate the safety and tolerability of PTL101 containing 10 and 100 mg CBD, following single administrations to healthy volunteers and to compare the pharmacokinetic profiles and relative bioavailability of CBD with Sativex oromucosal spray (the reference product) in a randomized, crossover study design...

INTRODUCTION: Differential diagnosis of Parkinson-plus patients (PSP, CBD, MSA) and Parkinson's disease (PD) patients is often not straightforward, particularly in atypical cases or at the initial stages of the diseases. Classic CSF biomarkers (amyloid-beta - Aβ42, tau protein - τT and phosphorylated tau protein - τP-181) are established biomarkers in the diagnosis of Alzheimer's disease (AD). CSF a-synuclein (α-syn) has emerged as a promising biomarker in patients with Parkinsonism...

The mechanism of action of cannabidiol (CBD), the main non-psychotropic component of Cannabis sativa L., is not completely understood. First assumed that the compound was acting via cannabinoid CB2 receptors (CB2Rs) it is now suggested that it interacts with non-cannabinoid G-protein-coupled receptors (GPCRs); however, CBD does not bind with high affinity to the orthosteric site of any GPCR. To search for alternative explanations, we tested CBD as a potential allosteric ligand of CB2R. Radioligand and non-radioactive homogeneous binding, intracellular cAMP determination and ERK1/2 phosphorylation assays were undertaken in heterologous systems expressing the human version of CB2R...

Cannabidiol (CBD) and ∆(9)-tetrahydrocannabinol (THC) have well documented immunomodulatory effects in vitro, but not following oral administration in humans. Here we show that oral co-administration of cannabinoids with lipids can substantially increase their intestinal lymphatic transport in rats. CBD concentrations in the lymph were 250-fold higher than in plasma, while THC concentrations in the lymph were 100-fold higher than in plasma. Since cannabinoids are currently in clinical use for the treatment of spasticity in multiple sclerosis (MS) patients and to alleviate nausea and vomiting associated with chemotherapy in cancer patients, lymphocytes from those patients were used to assess the immunomodulatory effects of cannabinoids...

Cannabidiol (CBD) has gained much attention in the past several years for its therapeutic potential in the treatment of drug-resistant epilepsy, such as Dravet Syndrome. While CBD has shown anecdotal efficacy in reducing seizure frequency, little is known regarding the potential adverse side-effects of CBD on physiology, development, organogenesis, or behavior. The goal of this project is to compare the relative morphological, behavioral, and gene expression phenotypes resulting after a developmental exposure to Δ9-tetrahydrocannabinol (THC) or CBD...

Exchange proteins directly activated by cAMP (EPACs) are critical cAMP-dependent signaling pathway mediators that play important roles in cancer, diabetes, heart failure, inflammations, infections, neurological disorders and other human diseases. EPAC specific modulators are urgently needed to explore EPAC's physiological function, mechanism of action and therapeutic applications. On the basis of a previously identified EPAC specific inhibitor hit ESI-09, herein we have designed and synthesized a novel series of 2-substituted phenyl-N-phenyl-2-oxoacetohydrazonoyl cyanides as potent EPAC inhibitors...

Introduction:Cannabis sativa (hemp) seeds are popular for their high nutrient content, and strict regulations are in place to limit the amount of potentially harmful phytocannabinoids, especially Δ(9)-tetrahydrocannabinol (Δ(9)-THC). In Canada, this limit is 10 μg of Δ(9)-THC per gram of hemp seeds (10 ppm), and other jurisdictions in the world follow similar guidelines. Materials and Methods: We investigated three different brands of consumer-grade hemp seeds using four different procedures to extract phytocannabinoids, and quantified total Δ(9)-THC and cannabidiol (CBD)...
