PURPOSE: Status epilepticus (SE) in patients with cirrhosis is a rare but serious situation. Diagnosis may be difficult in emergency presentation, especially when patients present with hepatic encephalopathy (HE). Misdiagnosis must be avoided since some anti-epileptic drugs aggravate HE. In this retrospective study, we therefore assessed the frequency of SE in patients with cirrhosis, evaluated the accuracy of diagnosis and determined rates of mortality. METHOD: We reviewed data from all patients hospitalized from 2005 to 2013 in the Hepatology ICU for complications of cirrhosis with an initial diagnosis of SE...

Synthetic glucocorticoids have been detected in environmental waters and their biological potency have raised concerns of their impact on aquatic vertebrates especially fish. In this study, developing zebrafish larvae exposed to representative glucocorticoids (dexamethasone, prednisolone and triamcinolone) at 50 pM to 50 nM from 3 h post-fertilisation to 5 days post-fertilisation were investigated. Microarray analysis identified 1255, 1531, and 2380 gene probes, which correspondingly mapped to 660, 882 and 1238 human/rodent homologs, as deregulated by dexamethasone, prednisolone and triamcinolone, respectively...

Selenium (Se)-enriched milk provides antioxidant benefits and has therapeutic potential against cancer. However, both antidiabetic and prodiabetic effects have been attributed to Se. Our objective was to evaluate the effect of Se-enriched milk casein on insulin sensitivity in rats when given at the requirement of 0.25 ppm Se and supranutritionally on both low- and high-fat diets. Two hundred sixteen male Sprague-Dawley rats were fed low- or high-fat diets containing one, two or eight times the Se requirement in a randomized block design...

This study investigated the biological and molecular mechanisms underlying the antiobesity effect of omija fruit ethanol extract (OFE) in mice fed a high-fat diet (HFD). C57BL/6J mice were fed an HFD (20% fat, w/w) with or without OFE (500 mg/kg body weight) for 16 weeks. Dietary OFE significantly increased brown adipose tissue weight and energy expenditure while concomitantly decreasing white adipose tissue (WAT) weight and adipocyte size by up-regulating the expression of brown fat-selective genes in WAT...

The present study explored the possible preventive effects of blue light emitting diodes (LEDs) on cadmium (Cd)-induced oxidative stress and immunotoxicity in zebrafish. To this end, zebrafish were exposed to a white fluorescent bulb or blue LEDs (LDB, peak at 450nm, at an irradiance of 0.9W/m(2)), and 0 or 30µgL(-1) waterborne Cd for 5 weeks. Growth performance, survival rate, and hepatic histology, ultrastructure, antioxidant and innate immune responses were determined in zebrafish. Cd exposure alone reduced growth and survival rate, and induced oxidative damage and changes in histology and ultrastructure...

The cytoplasmic polyadenylation element-binding (CPEB) proteins regulate pre-mRNA processing and translation of CPE-containing mRNAs in early embryonic development and synaptic activity. However, specific functions in adult organisms are poorly understood. Here we show that CPEB4 is required for adaptation to high-fat-diet- and ageing-induced endoplasmic reticulum (ER) stress, and subsequent hepatosteatosis. Stress-activated liver CPEB4 expression is dual-mode regulated. First, Cpeb4 mRNA transcription is controlled by the circadian clock, and then its translation is regulated by the unfolded protein response (UPR) through upstream open reading frames within the 5'UTR...

BACKGROUND AND AIM: Hepatic encephalopathy (HE) is a frequent complication of cirrhosis, characterized by cognitive deficits that negatively impact patients' quality of life. The mild, minimal hepatic encephalopathy (mHE) can only be detected by psychometric tests and early mHE detection can prevent more severe complications or even survival times. Here, we aimed to investigate the feasibility and validity of the novel-developed electronic number connection test (eNCT), which is designed as a fast and easy-to-perform mHE patient self-test...

This study investigated the prevalence of inclusion body hepatitis (IBH) infections during the past five years (2010-2014) in broiler chicken flocks in Poland. The diagnosis of IBH was based on anatomopathological investigations and histopathological analyzes. IBH was the most prevalent disease in broiler flocks in Poland (10.4%) during this time period, and occurred as a primary infection. The fewest cases of IBH occurred in the summer, suggesting that the temperature may have been a possible stressor that increased susceptibility to IBH...

Purpose To develop a method to incorporate the propagation of contrast material into computational anthropomorphic phantoms for estimation of organ dose at computed tomography (CT). Materials and Methods A patient-specific physiologically based pharmacokinetic (PBPK) model of the human cardiovascular system was incorporated into 58 extended cardiac-torso (XCAT) patient phantoms. The PBPK model comprised compartmental models of vessels and organs unique to each XCAT model. For typical injection protocols, the dynamics of the contrast material in the body were described according to a series of patient-specific iodine mass-balance differential equations, the solutions to which provided the contrast material concentration time curves for each compartment...

Hepatitis C virus (HCV) infection is currently the most important cause of chronic viral hepatitis in the world and one of the most frequent indications for liver transplantation. HCV uses different strategies to evade the innate and adaptive immune response, and this evasion plays a key role in determining viral persistence. Several HCV viral proteins have been described as immune modulators. In this review, we will focus on the effect of HCV nucleocapsid core protein in the function of immune cells and its correlation with the findings observed in HCV chronically infected patients...

Migrant Chinese populations in Western countries have a high prevalence of chronic hepatitis B but often experience poor access to healthcare and late diagnosis. This systematic review aimed to identify obstacles and supports to timely and appropriate health service use among these populations. Systematic searches resulted in 48 relevant studies published between 1996 and 2015. Data extraction and synthesis were informed by models of healthcare access that highlight the interplay of patient, provider and health system factors...

Hepatitis A vaccine is recommended for children ≥1 year old to prevent hepatitis A virus (HAV) infection. However the duration of vaccine-induced immunity is unknown. We evaluated a cohort of Alaska Native persons 20 years after HAV vaccination. Children aged 3-6 years had been previously randomized to receive 3 doses of HAV vaccine (360 ELISA units/dose) at: A) 0,1,2 months; B) 0,1,6 months; and C) 0,1,12 months. We measured anti-HAV antibody concentrations every 2-3 years; described geometric mean concentrations (GMC) and the proportion with protective antibody (≥20 mIU mL-1) over time; and modelled change in GMC using fractional polynomial regression...

Hepatitis B virus surface antigen (HBsAg) carriers are highly susceptible to liver injury triggered by environmental biochemical stimulation. Previously, we have reported an inverse correlation between γδT cells and liver damage in patients with HBV. However, whether γδT cells play a role in regulating the hypersensitivity of HBsAg carriers to biochemical stimulation-induced hepatitis is unknown. In this study, using hepatitis B virus transgenic (HBs-Tg) and HBs-Tg-TCRδ(-/-) mice, we found that mice genetically deficient in γδT cells exhibited more severe liver damage upon ConcanavalinA (ConA) treatment, as indicated by substantially higher serum alanine aminotransferase (ALT) levels, further elevated IFN-γ levels and more extensive necrosis...

PURPOSE OF REVIEW: This review seeks to describe the role of the asialoglycoprotein receptor (ASGR) in modulating non-HDL lipoprotein levels, platelet numbers and atherosclerosis. RECENT FINDINGS: Genetics studies have revealed that ASGR haplodeficiency provides protection from atherosclerosis. The potential interactions of ASGR with LDL receptor may regulate the rate of LDL uptake and as a result may lower plasma non-HDL cholesterol. ASGR clears senescent platelets and induces the expression of hepatic thrombopoietin...

Hepatitis delta virus (HDV) is a defective satellite virus and propagates in the presence of Hepatitis B virus (HBV) surface antigen (HBsAg). Approximately 5% of the people who infected with HBV are also infected with HDV. Chronic hepatitis caused by delta is the most severe form of chronic viral hepatitis including accelerated fibrosis, liver decompensation and development of hepatocellular carcinoma. Interferon-based therapies still remain the only treatment option of the hepatitis delta. The beneficiary effects of the interferon-based therapies, however, stop frequently with termination of the given therapy and relapse rate is very high...

Hepatitis C virus (HCV) infects nearly 170 million people worldwide and is a leading cause of progressive liver damage, cirrhosis, and hepatocellular carcinoma. Curative therapies have historically relied on interferon-based treatments and were limited by significant toxicity and poor response rates, particularly among patients with prior treatment failure and advanced hepatic fibrosis. The recent advent of direct acting antiviral (DAA) agents which target key steps in the HCV viral life cycle has transformed the landscape of HCV treatment by offering highly effective and well tolerated interferon-free treatments...

Flubendazole (FLBZ) is a broad-spectrum benzimidazole anthelmintic used in pigs, poultry, and humans. It has been proposed as a candidate for development for use in elimination programmes for lymphatic filariasis and onchocerciasis in humans. Moreover, FLBZ has shown promise in cancer chemotherapy, particularly for neuroblastoma. This work investigated the hepatic carbonyl-reducing pathway of FLBZ in different species, including humans. Microsomal and cytosolic fractions were obtained from sheep, cattle, pig, hen, rat, and human liver...
