Important aspects of the selection of probiotics to be used for mixing in animal feed include host species specificity and probiotic cell survival during production and storage of their products. The research was to screen and investigate some probiotic properties of lactic acid bacteria (LAB) isolated from pig fecal samples. One hundred and thirty-eight representative LAB isolates, which were isolated from 51 pig fecal samples, were tested for acid and bile tolerance, antimicrobial susceptibility, antibacterial activity, potential adhesion to the cell surface, and survival rates when stored in varied microencapsulation forms: freeze-dried, spray-dried, and micro-beads...

A 71-year-old male presented to our institution with cholestatic hepatitis after having recently undergone upper endoscopy for treatment of gastrointestinal bleeding. Further investigation with endoscopic retrograde cholangiopancreatography revealed a hemostatic clip on the ampulla of Vater. After initial attempts at cannulation of the common bile duct were unsuccessful, biliary decompression was achieved by use of needle-knife fistulotomy. A common bile duct stent was placed and the liver function tests improved prior to discharge...

Nonalcoholic fatty liver disease (NAFLD) is a burgeoning health problem worldwide, ranging from nonalcoholic fatty liver (NAFL, steatosis without hepatocellular injury) to the more aggressive nonalcoholic steatohepatitis (NASH, steatosis with ballooning, inflammation, or fibrosis). Although many studies have greatly contributed to the elucidation of NAFLD pathogenesis, the disease progression from NAFL to NASH still remains incompletely understood. Nuclear receptor small heterodimer partner (Nr0b2, SHP) is a transcriptional regulator critical for the regulation of bile acid, glucose, and lipid metabolism...

SCOPE: Mannan oligosaccharides (MOS) have proven effective at improving growth performance, while also reducing hyperlipidemia and inflammation. As atherosclerosis is accelerated both by hyperlipidemia and inflammation, we aimed to determine the effect of dietary MOS on atherosclerosis development in hyperlipidemic ApoE*3-Leiden.CETP (E3L.CETP) mice, a well-established model for human-like lipoprotein metabolism. METHODS AND RESULTS: Female E3L.CETP mice were fed a high cholesterol diet, with or without 1% MOS for 14 weeks...

Cirrhotic patients are often exposed to antibiotics that can lead to resistance and fungal overgrowth. The role of fecal microbial transplant (FMT) to restore gut microbial function is unclear in cirrhosis. In an FDA-monitored Phase 1 clinical safety trial, decompensated cirrhotic patients on standard therapies (lactulose and rifaximin) were randomized to standard-of-care (SOC, no antibiotics/FMT) or 5 days of broad-spectrum antibiotics followed by FMT from a donor enriched in Lachnospiraceae and Ruminococcaceae...

Liver fibrosis and cirrhosis are characterized by activation of hepatic stellate cells (HSC) which is associated with higher intracellular pH (pHi). The vacuolar H+ adenosine-tri-phosphatase (v-ATPase) multi-subunit complex is a key regulator of intracellular pH homeostasis. The present work was aimed at investigating the functional role of v-ATPase in primary human HSC (hHSC) activation and its modulation by specific AMPK subunits. Here, we demonstrated that the expression of different v-ATPase subunits was increased in in vivo and in vitro activated hHSC, compared to non-activated hHSC...

Background: Hand flexor tendon injuries are compromised with tendon adhesion. Tendon adhesion forms between flexor tendon and tendon sheath, reduces the range of motion of fingers, and affects their function. Oxidative stress is increased in flexor tendon after injury and might play a role in tendon adhesion formation. Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid), a water-soluble analog of vitamin E, is antioxidative. Trolox reduced oxidative stress and the expression of fibrotic cytokines in the bile gut ligation animal model...

Transfer of antibiotic resistance genes from probiotic bacteria to pathogens poses a safety concern. Orally administered probiotics are exposed to stressful conditions during gastrointestinal transit. In this study, filter mating experiments were performed to investigate the potential role of exposure of Bifidobacterium isolates to acid and bile stress on the transfer of a tetracycline resistance gene, tet (W), to Enterococcus faecalis ATCC 51299. No E. faecalis transconjugants were obtained after mating with either stressed or unstressed Bifidobacterium , thereby suggesting that tet (W) could not be transferred as a result of exposure to gastrointestinal stresses...

Non-alcoholic fatty liver disease (NAFLD) is the most frequent hepatic pathology in the Western world and may evolve into steatohepatitis (NASH), increasing the risk of cirrhosis, portal hypertension and hepatocellular carcinoma. NAFLD derives from the accumulation of hepatic fat due to discrepant free fatty acid metabolism. Other factors contributing to this are deranged nutrients and bile acids fluxes as well as alterations in nuclear receptors, hormones, and intermediary metabolites, which impact on signaling pathways involved in metabolism and inflammation...

BACKGROUND: Transient elastography (TE) is a noninvasive technique that measures liver stiffness. When an inflammatory process is present, this is shown by elevated levels of stiffness. Acute cellular rejection (ACR) is a consequence of an inflammatory response directed at endothelial and bile epithelial cells, and it is diagnosed through liver biopsy. This is a systematic review of the viability of TE in ACR following liver transplantation. METHODS: The Cochrane Library, Embase, and Medline PubMed databases were searched and updated to November 2016...

Patients with cirrhosis have reduced systemic vascular resistance and elevated circulating bile acids (BAs). Previously, we showed that secondary conjugated BAs impair vascular tone by reducing vascular smooth muscle cell (VSMC) Ca2+ influx. In this study, we investigated the effect of deoxycholylglycine (DCG), on Ca2+ sensitivity in reducing vascular tone. First, we evaluated the effects of DCG on U46619- and phorbol-myristate-acetate (PMA)-induced vasoconstriction. DCG reduced U46619-induced vascular tone but failed to reduce PMA-induced vasoconstriction...

Cholestasis is a clinical syndrome with systemic and intrahepatic accumulation of excessive toxic bile acids that ultimately cause hepatobiliary injury. Recently obeticholic acid (OCA) which is a farnesoid X receptor (FXR) agonist was approved by FDA to treat cholestatic liver diseases, which provided us a newly therapeutic strategy against cholestasis. The purpose of the current study is to screen novel FXR agonists and verify the anti-cholestasis effect of yangonin in vivo and in vitro. The computational strategy of two-dimensional virtual screening was used to search for new FXR agonists, and dual-luciferase reporter gene assay was used to further demonstrate FXR activation by yangonin...
