Glioblastoma (GBM) is the most common primary malignant brain tumor in adults. The challenging problem in cancer treatment is to find a way to upregulate radiosensitivity of GBM while protecting neurons and neural stem/progenitor cells in the brain. The goal of the present study was upregulation of the cytotoxic effect of γ-irradiation in GBM by non-psychotropic and non-toxic cannabinoid, canna...

Corticobasal degeneration (CBD) was initially thought to represent a clinicopathological entity, but recent studies have shown its considerable clinicopathological heterogeneity. Thus, the constellation of the findings initially considered characteristic of CBD is now named "corticobasal syndrome" (CBS), while the term "CBD" is used for the histopathological disorder. Multiple phenotypes associ...

Accepted guidelines for preoperative endoscopic retrograde cholangiopancreatography (ERCP) in gallstone pancreatitis are lacking. Our previous investigations suggested that serum total bilirubin on hospital Day 2 best predicts persisting common bile duct (CBD) stones. We aim to identify an optimal total bilirubin threshold on hospital Day 2 that would predict persisting CBD stones and guide obt...

BACKGROUND AND PURPOSE Three-dimensional imaging and hemispheric volumetry are useful for the assessment of degenerative cortical atrophy. Our purpose was to determine the features of cortical atrophy in progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) by means of a hemispheric surface display generated with MR images. METHODS The extent of cortical atrophy was evaluat...

BACKGROUND T-tube placement in the common bile duct (CBD) is a surgical alternative to bile duct reconstruction in cholecystectomy for cholecysto-choledocholithiasis, or gallstones. The aim of this retrospective clinical study was to investigate the incidence of late complications of T-tube placement. MATERIAL AND METHODS Retrospective review identified 35 patients who had T-tube placement duri...

Cannabinoids are known to exert immunosuppressive activities. However, the mechanisms which contribute to these effects are unknown. Using lipopolysaccharide (LPS) to activate BV-2 microglial cells, we examined how Δ(9)-tetrahydrocannabinol (THC), the major psychoactive component of marijuana, and cannabidiol (CBD) the non-psychoactive component, modulate the inflammatory response. Microarray a...

We describe a 66-year-old Caucasian man with type 1 Mirizzi syndrome diagnosed on endoscopic ultrasound. He presented with acute onset of jaundice, malaise, dark urine over 3-4 days, and was found to have obstructive jaundice on lab testing. CT scan of the abdomen showed intrahepatic biliary ductal dilation, a 1.5 cm common bile duct (CBD) above the pancreas, and possible stones in the CBD, but...

BACKGROUND Less than 67% of patients with intermediate risk for common bile duct (CBD) stones require therapeutic intervention. It is important to have an accurate, safe, and reliable method for the definitive diagnosis of CBD stones before initiating therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Few publications detail the diagnostic efficacy of linear echoendoscopy (EUS) ...

Cannabidiol (CBD), a major nonpsychoactive constituent of cannabis, is considered an antineoplastic agent on the basis of its in vitro and in vivo activity against tumor cells. However, the exact molecular mechanism through which CBD mediates this activity is yet to be elucidated. Here, we have shown CBD-induced cell death of breast cancer cells, independent of cannabinoid and vallinoid recepto...

This short communication examines the question whether the experimental data presented in a study by Merrick et al. are of clinical relevance. These authors found that cannabidiol (CBD), a major cannabinoid of the cannabis plant devoid of psychotropic effects and of great interest for therapeutic use in several medical conditions, may be converted in gastric fluid into the psychoactive cannabin...
