Previous studies suggest that dietary salecan (a water-soluble β-glucan) effectively reduces high-fat-diet-induced adiposity through disturbing bile-acid-promoted emulsification in mice. However, the effects of salecan on metabolic genes and metabolites involved in lipid accumulation are mostly unknown. Here, we confirmed that dietary 3% and 6% salecan for 4 weeks markedly decreased fat accumulation in liver and adipose tissue in high-fat-diet rats, displaying a decrease in mRNA levels of SREBP1-C, FAS, SCD1 and ACC1 involved in de novo lipogenesis and a reduction of levels of GPAT1, DGAT1 and DGAT2 related to triglyceride synthesis...

Increasing evidence has demonstrated that exposure to endocrine disrupting chemicals (EDCs) impacts maternal and fetal health, but the underlying mechanisms are still unclear. We have previously shown that dietary exposure to 10 µg/kg bw/day and 10 mg/kg bw/day bisphenol A (BPA) during pregnancy induced metabolic abnormalities in F1 male offspring and gestational glucose intolerance in F0 pregnant mice. The aim of this study is to elucidate the underlying etiologies of BPA exposure-induced metabolic disease by analyzing male fetal liver metabolome...

Wisteria floribunda agglutinin (WFA) is a useful probe for distinguishing glycan structural alterations in diseases such as intrahepatic bile duct carcinoma and hepatic fibrosis; however, the gene encoding WFA has not been identified. Here, we identified the gene encoding WFA, and recombinant WFA was expressed in Escherichia coli and purified. The natural cDNA sequence obtained from wisteria seeds contained an open reading frame of 861 nucleotides encoding a WFA precursor, which included a hydrophobic signal peptide at the N-terminus, a propeptide at the C-terminus and a single cysteine (Cys) residue for dimer formation...

Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) are anatomically different bariatric operations. RYGB achieves greater weight loss compared with LAGB. Changes in the gut microbiome have been documented after RYGB, but not LAGB, and the microbial contribution to sustainable surgical weight loss warrants further evaluation. We hypothesized that RYGB imposes greater changes on the microbiota and its metabolism than LAGB, and that the altered microbiota may contribute to greater weight loss...

Morphine produces contraction of Oddi’s sphincter, which can be severe and of longer duration in some pathological conditions. This exaggerated response can manifest as a colicky biliary pain, frequently accompanied by a dramatic increase in hepatic enzymes. We report a 32 years old female who consulted in the emergency room for severe low abdominal pain of gynecologic origin, which was completely controlled by morphine. However, she presented a sudden epigastric colicky pain irradiating in the back, which persisted for several hours in spite of the repeated administration of analgesics...

The synthesis of a small collection of novel bile acid-bisphosphonate (BA-BP) conjugates as potential drug candidates is reported. The disclosed methodology relied on the installation of azide and thiol functionalities at the head and tail positions, respectively, of the BA scaffold and its subsequent decoration by orthogonal click reactions (copper-catalyzed azide-alkyne cycloaddition, thiol-ene or thiol-yne coupling) to introduce BP units and a fluorophore. Because of the troublesome isolation of the target conjugates by standard procedures, the methodology culminated with the functionalization of the BA scaffold with a light fluorous tag to rapidly and efficiently purify intermediates and final products by fluorous solid-phase extraction...

BACKGROUND: Delayed gastric emptying (DGE), a common postoperative complication of pancreaticoduodenectomy (PD), is not considered a life-threatening complication. In this study, we analyzed the risk factors for DGE and its impact on long-term prognosis. METHODS: We analyzed 383 patients who underwent PD between 2003 and 2010, dividing them into two groups according to DGE grade as defined by the International Study Group of Pancreatic Surgery: 243 without DGE (Non-DGE Group) and 140 with DGE of any grade (DGE Group)...

BACKGROUND/AIMS: Intraoperative cholangiogram (IOC) is commonly used to detect retained bile duct stones. This often leads to another invasive procedure such as endoscopic retrograde cholangiopancreatography (ERCP). However, due to the variation in methods and results of IOC, it is unclear if clinical factors will aid in identifying true choledocholithiasis. METHODS: All cholecystectomies in a 3 year period were examined retrospectively for positive IOC. Sonographic bile duct dilation and transaminase levels at admission including trends during the course of hospitalization and prior to ERCP were evaluated...

BACKGROUND/PURPOSE: The clinical relevance of a high-grade dysplasia/carcinoma in situ (HD/CIS)-positive bile duct margin in perihilar cholangiocarcinoma (PHC) is unclear. We evaluated the surgical outcomes of PHC patients with HD/CIS. METHODS: Clinicopathological data of 163 consecutive patients who underwent resection of PHC between 2004 and 2013 were analyzed retrospectively. RESULTS: Postoperative states included curative (R0) resection with free margins in 113 patients, non-curative resection with HD/CIS (R1-HD/CIS) in 22 patients, and non-curative resection with any invasive carcinoma margin (R1-INV) in 28 patients...

BACKGROUND: Despite the improvements of surgical techniques and postoperative management of patients with liver transplantation, biliary complications are one of the most common and important adverse events. We present a first case of choledochoduodenostomy using magnetic compression following a massive resection of the small intestine due to strangulated ileus after living donor liver transplantation. CASE PRESENTATION: The 54-year-old female patient had end-stage liver disease, secondary to liver cirrhosis, due to primary sclerosing cholangitis with ulcerative colitis...

BACKGROUND AND OBJECTIVE: Gliclazide is a drug commonly used in type 2 diabetes mellitus. Recently, gliclazide has shown desirable pharmacological effects such as immunoregulatory and anti-clotting effects, which suggests potential applications in type 1 diabetes mellitus (T1DM). Gliclazide has variable absorption after oral administration, and thus using targeted-delivery techniques, such as microencapsulation, may optimise gliclazide absorption and potential applications in T1DM. Bile acids such as cholic acid have shown microcapsule-stabilising and controlled-release effects, and thus their incorporation into gliclazide microcapsules may further optimise gliclazide release, absorption and antidiabetic effects...

Primary Biliary Cholangitis, previously known as Primary Biliary Cirrhosis, is a rare disease, which mainly affects women in their fifth to seventh decades of life. It is a chronic autoimmune disease characterized by a progressive damage of interlobular bile ducts leading to ductopenia, chronic cholestasis and bile acids retention. Even if the disease usually presents a long asymptomatic phase and a slow progression, in many patients it may progress faster toward cirrhosis and its complications. The 10year mortality is greater than in diseases such as human immunodeficiency virus/Hepatitis C Virus coinfection and breast cancer...

Hepatitis B is one of the most common infectious diseases globally. It has been estimated that there are 350 million chronic hepatitis B virus (HBV) carriers worldwide. The liver is connected to the small intestine by the bile duct, which carries bile formed in the liver to the intestine. Nearly all of the blood that leaves the stomach and intestines must pass through the liver. Human intestines contain a wide diversity of microbes, collectively termed the 'gut microbiota'. Gut microbiota play a significant role in host metabolic processes and host immune modulation, and influence host development and physiology (organ development)...

Cholangiocarcinoma is an epithelial malignancy arising in the region between the intrahepatic bile ducts and the ampulla of Vater at the distal end of the common bile duct. The effect of current chemotherapy regimens against cholangiocarcinoma is limited, and the prognosis of patients with cholangiocarcinoma is poor. Aberrant DNA methylation and histone modification induce silencing of tumor suppressor genes and chromosomal instability during carcinogenesis. Studies have shown that the tumor suppressor genes and microRNAs (miRNAs) including MLH1, p14, p16, death-associated protein kinase (DAPK), miR-370 and miR-376c are frequently methylated in cholangiocarcinoma...

Hepatic cystogenesis in Polycystic Liver Disease (PLD) is associated with increased levels of cAMP in cholangiocytes lining liver cysts. TGR5, a G protein-coupled bile acid receptor, is linked to cAMP and expressed in cholangiocytes. Therefore, we hypothesized that TGR5 might contribute to disease progression. We examined expression of TGR5 and Gα proteins in cultured cholangiocytes and in livers of animal models and humans with PLD. In vitro, we assessed cholangiocyte proliferation, cAMP levels, and cyst growth in response to: (i) TGR5 agonists [taurolithocholic acid (TLCA), oleanolic acid (OA) and two synthetic compounds]; (ii) a novel TGR5 antagonist (SBI-115); and (iii) a combination of SBI-115 and pasireotide, a somatostatin receptor (SSTR) analog...

The glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) exenatide and lixisenatide reduce cholecystokinin (CCK)-induced gallbladder emptying in healthy subjects. It is unknown if all GLP-1 RAs share this effect; therefore, the effect of the GLP-1 RA albiglutide on gallbladder function was assessed. In this randomized, double-blind, 2-way crossover study, a single dose of subcutaneous albiglutide 50 mg or placebo was administered to 17 healthy subjects, and CCK-induced gallbladder contractility was measured by ultrasonography...
