OBJECTIVE: Recently, a benzofuran derivative for the imaging of β-amyloid plaques, 5-(5-(2-(2-(2-18 F-fluoroethoxy)ethoxy)ethoxy)benzofuran-2-yl)- N-methylpyridin-2-amine (18 F-FPYBF-2) has been validated as a tracer for amyloid imaging and it was found that18 F-FPYBF-2 PET/CT is a useful and reliable diagnostic tool for the evaluation of AD (Higashi et al. Ann Nucl Med, , 2018). The aim of this study was to assess the biodistribution and radiation dosimetry of diagnostic dosages of18 F-FPYBF-2 in normal healthy volunteers as a first-in-man study...

Spontaneous right hepatic artery branch gallbladder fistula is a rare condition. Our case reported a spontaneous fistula between the right branch of the hepatic artery and the gall bladder. It constitutes a rare cause of haemobilia. In fact, the most common aetiology of haemobilia is traumatic or iatrogenic secondary to hepatobiliary surgery or interventions. Diagnosis of vascular-biliary fistula is not easy. The gallbladder endoluminal clot can mimic a mass, as in our patient. Selective arterial angiography is helpful in identifying the source of gastrointestinal haemorrhage...

Cholangiopathies are progressive disorders with largely unknown pathoetiology and limited treatment options. We aimed to develop a novel surgical technique with direct access to the bile ducts that would complement existing mouse models of cholestasis, biliary inflammation, and fibrosis and present a new route of administration for testing of potential treatment strategies. We developed a surgical technique to access the murine biliary tree by injection of different solvents through catheterization of the gall bladder with simultaneous clamping of the common bile duct...

Arsenicosis, a syndrome caused by ingestion of arsenic contaminated drinking water, currently affects millions of people in South-East Asia and elsewhere. Previous animal studies revealed that the toxicity of arsenite essentially can be abolished if selenium is co-administered as selenite. Although subsequent studies have provided some insight into the biomolecular basis of this striking antagonism, many details of the biochemical pathways that ultimately result in the detoxification and excretion of arsenic using selenium supplements have yet to be thoroughly studied...

Bile salts and bacteria have intricate relationships. The composition of the intestinal pool of bile salts is shaped by bacterial metabolism. In turn, bile salts play a role in intestinal homeostasis by controlling the size and the composition of the intestinal microbiota. As a consequence, alteration of the microbiome-bile salt homeostasis can play a role in hepatic and gastrointestinal pathological conditions. Intestinal bacteria use bile salts as environmental signals and in certain cases as nutrients and electron acceptors...

A variant anatomy of the hepatic vasculature has a clinically significant role in hepatobiliary transplantation, resection, tumour embolisation as well as in extrahepatic abdominal surgeries involving the stomach, pancreas or gall bladder. During routine cadaveric dissection, we observed a case of unusually small calibre hepatic artery proper. An accessory hepatic artery was seen emerging from the superior mesenteric artery to the right hepatic lobe along with an accessory hepatic vein from the right hepatic lobe that drained directly into the inferior vena cava...

All diagnostic algorithms for Neonatal Cholestasis Syndrome (NCS) focus on differentiating numerous medical causes from Biliary Atresia (BA). No preoperative diagnostic algorithm has 100% diagnostic accuracy for BA and yet, timely diagnosis is crucial to optimize surgical outcome. Markers for high index of clinical suspicion for BA are: a "usually" well thriving infant with conjugated hyperbilirubinemia, raised gamma glutamyl transpeptidase, persistently "acholic" stools, firm hepatomegaly with dysmorphic, hypoplastic gall bladder...

BACKGROUND Gallbladder agenesis (GA) is an extremely rare anatomic anomaly with a reported incidence of less than 0.5%. It is usually asymptomatic, but can present with features of biliary colic and cholecystitis. We present here a case of GA in a patient with recurrent biliary colic.  CASE REPORT A 24-year-old African American woman presented with recurrent episodes of right upper-quadrant abdominal pain. During her first episode, she was found to have elevated transaminases and clinical features of cholecystitis, but ultrasound did not visualize a gallbladder and she was discharged with a diagnosis of biliary colic...

The neuropeptide Y (NPY) Y1 receptor (Y1R) selective radioligand (R)-N(α)-(2,2-diphenylacetyl)-N(ω)-[4-(2-[(18)F]fluoropropanoylamino)butyl]aminocarbonyl-N-(4-hydroxybenzyl)argininamide ([(18)F]23), derived from the high-affinity Y1R antagonist BIBP3226, was developed for imaging studies of Y1R-positive tumors. Starting from the argininamide core bearing amine-functionalized spacer moieties, a series of fluoropropanoylated and fluorobenzoylated derivatives was synthesized and studied for Y1R affinity. The fluoropropanoylated derivative 23 displayed high affinity (Ki = 1...

BACKGROUND: Copper and zinc are essential micronutrients and cofactors of many enzymatic reactions that may be involved in liver-cancer development. We aimed to assess pre-diagnostic circulating levels of copper, zinc and their ratio (Cu/Zn) in relation to hepatocellular carcinoma (HCC), intrahepatic bile duct (IHBD) and gall bladder and biliary tract (GBTC) cancers. METHODS: A nested case-control study was conducted within the European Prospective Investigation into Cancer and Nutrition cohort...

Objectives The objective was to evaluate the safety and diagnostic utility of percutaneous ultrasound-guided cholecystocentesis (PUC) in cats with suspected hepatobiliary disease. Methods Medical records of 83 cats with suspected hepatobiliary disease that underwent PUC were retrospectively reviewed. Results At the time of PUC, at least one additional procedure was performed in 79/83 cats, including hepatic aspiration and/or biopsy (n = 75) and splenic aspiration (n = 18). Complications were noted in 14/83 cases, including increased abdominal fluid (n = 11), needle-tip occlusion (n = 1), failed first attempt to penetrate the gall bladder wall (n = 1) and pneumoperitoneum (n = 1)...

BACKGROUND: Once it is established that a jaundiced infant has direct hyperbilirubinemia, the principal diagnostic concern is to differentiate hepatocellular from obstructive cholestasis. Traditional tests such as ultrasonography, percutaneous liver biopsy and technetium 99 m hepatobiliary iminodiacetic acid (HIDA) scan are often not sufficiently discriminating. Definitive exclusion of biliary atresia (BA) in the infant with cholestatic jaundice usually requires mini-laparotomy and intra-operative cholangiography...

BACKGROUND: MRCP is the method of choice in diagnosing pathologies of the biliary system. One of them is bile fistulae. They are uncommon but tend to cause many diagnostic problems. The possible way to improve MRCP is using it with intravenous injection of hepatobiliary-specific contrast agents. As it is eliminated via the hepatobiliary system, it can be visualized in the bile ducts and may help to reveal disorders undetected by a standard MRCP. CASE REPORT: We report a case of a 36-year-old woman with leakage in the biliary system which led to creation of a subcutaneous bile reservoir...

The first decade of the twenty-first century witnessed the presence and light microscopic, immunophenotypic, and ultrastructural characterization of interstitial Cajal-like cells (coined as 'telocytes') in virtually every extragastrointestinal site of the human body by Laurentiu M. Popescu and his co-workers. Not surprisingly, stromal tumours, immunophenotypically similar to that of telocytes [CD117 (c-KIT) +/CD34 +], have also been sporadically reported outside the tubular gut (so-called extragastrointestinal stromal tumours, EGISTs), including the gall bladder, liver, and pancreas...

Hepatobiliary cystadenomas are mucinous cystic neoplasms arising in the liver, extrahepatic bile ducts or gall bladder. Extrahepatic cystadenomas are rare neoplasms requiring complete excision as there is a chance for recurrence and malignant transformation. Angiomyolipoma (AML) belongs to the perivascular epithelioid cell group of neoplasms, and kidney is the commonest site involved. We report a case of an unusual combination of extrahepatic biliary cystadenoma with angiomyolipoma in an adult female without evidence of tuberous sclerosis...

BACKGROUND: Silver nanoparticles (AgNPs) are an important class of nanomaterials used as antimicrobial agents for a wide range of medical and industrial applications. However toxicity of AgNPs and impact of their physicochemical characteristics in in vivo models still need to be comprehensively characterized. The aim of this study was to investigate the effect of size and coating on tissue distribution and toxicity of AgNPs after intravenous administration in mice, and compare the results with those obtained after silver acetate administration...

Certain arsenic and selenium compounds show a remarkable mutual cancelation of toxicities, where a lethal dose of one can be voided by an equimolar and otherwise lethal dose of the other. It is now well established that the molecular basis of this antagonism is the formation and biliary excretion of seleno bis-(S-glutathionyl) arsinium anion [(GS)2AsSe](-). Previous work has definitively demonstrated the presence of [(GS)2AsSe](-) in rabbit bile, but only in the presence of other arsenic and selenium species...
