Epithelial Cell Adhesion Molecule (EpCAM), or CD326, is a trans-membrane glycoprotein expressed by multiple normal epithelia as well as carcinoma. Human hepatic stem cells and bile duct epithelium of the liver are EpCAM positive. In tumor cell lines, its intracellular domain can be released after cleavage of the extracellular domain. Within the cell nucleus it induces cell proliferation, but cleavage depends on cell contact. Fragments of various lengths have been described in tumor cells. Despite of its described important role in proliferation in tumor cells, there is not much known about the expression and role of EpCAM fragments in primary human liver cells...

Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease with manifestation of over-accumulation of fat in liver. Increasing evidences indicate that NAFLD may be in part caused by malfunction of very low density lipoprotein (VLDL) secretion. Hepatocyte nuclear factor 4α (HNF4α), a nuclear receptor protein, plays an important role in sustain hepatic lipid homeostasis via transcriptional regulation of genes involved in secretion of VLDL, such as apolipoprotein B (ApoB). However, the exact functional change of HNF4α in NAFLD remains to be elucidated...

BACKGROUND: Psoriasis associates several extra-cutaneous manifestations. Little is known about hepatic parameters specifically associated with psoriasis. OBJECTIVE: To study whether psoriasiform dermatitis is associated with liver injury. METHODS: We studied liver parameters of inflammation and fibrosis in a murine model of psoriasiform dermatitis induced by topical application of imiquimod for nine weeks. RESULTS: Topical treatment with imiquimod induced a form of psoriasiform dermatitis reminiscent of the human disorder, characterized by thickened and scaly skin, psoriasiform epidermal hyperplasia, altered keratinocyte differentiation, and cutaneous overexpression of interleukin-17A...

BACKGROUND: The persistent scarcity of donors has prompted liver transplantation teams to find solutions for increasing graft availability. We report our experience of liver transplantations performed with grafts from older donors, specifically over 70 and 80 years old. PATIENTS AND METHODS: We analyzed our prospectively maintained single-center database from January 1, 2005, to December 31, 2014, with 380 liver transplantations performed in 354 patients. Six groups were composed according to donor age: <40 (n = 84), 40 to 49 (n = 67), from 50 to 59 (n = 62), from 60 to 69 (n = 76), from 70 to 79 (n = 64), and ≥80 years (n = 27)...

INTRODUCTION: Hepatitis C virus (HCV)-related cirrhosis remains the commonest indication for liver transplantation worldwide, yet few studies have investigated the impact of donation after circulatory death (DCD) graft use on HCV recurrence and patient outcomes. DCD grafts have augmented the limited donor organ pool and reduced wait-list mortality, although concerns regarding graft longevity and patient outcome persist. METHODS: This was a single-center study of all HCV + adults who underwent DCD liver transplantation between 2004 and 2014...

BACKGROUND: Despite the progressively increasing gap between patients waiting for liver transplant under the Model for End-stage Liver Disease MELD system and the availability of deceased donor organs, the use of right extended split liver grafts (RESLG) has not been accepted by all centers. In this study, we compared the results obtained using RESLG vs a group of matched whole liver graft (WLG) recipients at a single center in Latin America. METHODS: A single-center retrospective review performed between August 2009 and December 2015...

Gastrointestinal (GI) manifestations of rheumatoid arthritis (RA) are rare, but can be impactful for patients. Some GI processes are directly related to RA, whereas others may be sequelae of treatment or caused by concomitant autoimmune diseases. This article discusses the role of the GI tract in RA pathogenesis; the presentation, epidemiology, and diagnosis of RA-related GI manifestations; concomitant GI autoimmune diseases that may affect those with RA; and GI side effects of RA treatment. The importance of appropriately considering conditions unrelated to RA in the differential diagnosis when evaluating new GI symptoms in patients with RA is noted...

BACKGROUND: To ensure sustainability of aquaculture, plant-based ingredients are being used in feeds to replace marine-derived products. However, plants contain secondary metabolites which can affect food intake and nutrient utilisation of fish. The application of nutritional stimuli during early development can induce long-term changes in animal physiology. Recently, we successfully used this approach to improve the utilisation of plant-based diets in diploid and triploid Atlantic salmon...

Inflammatory lesions in the brain activate a systemic acute phase response (APR), which is dependent on the release of extracellular vesicles (EVs) into the circulation. The resulting APR is responsible for regulating leukocyte mobilization and subsequent recruitment to the brain. Factors that either exacerbate or inhibit the APR will also exacerbate or inhibit CNS inflammation as a consequence, and have the potential to influence ongoing secondary damage. Here, we were interested to discover how the circulating EV population changes after traumatic brain injury (TBI) and how manipulation of the circulating EV pool impacts on the outcome of TBI...

BACKGROUND: Hepatocellular carcinoma (HCC) causes over 800,000 deaths worldwide annually, mainly in low income countries, and incidence is rising rapidly in the developed world with the spread of hepatitis B (HBV) and C (HCV) viruses. Natural Killer (NK) cells protect against viral infections and tumours by killing abnormal cells recognised by Killer-cell Immunoglobulin-like Receptors (KIR). Thus genes and haplotypes encoding these receptors may be important in determining both outcome of initial hepatitis infection and subsequent chronic liver disease and tumour formation...

Hepatitis C virus (HCV) modulates immune-related inflammatory responses to induce milder reactions leading to virus persistence. In this regard, the present study aimed to investigate the link between the HCV genotypes and the proinflammatory and regulatory cytokine levels. Ninety patients with hepatitis C infection (68 treatment-naive and 22 treated patients) and 76 healthy blood donors were studied. The serum levels of IFN-γ, IL-10, IL-17A, and IL-21 were measured by ELISA in the patients and healthy controls...

Bifenthrin, a pyrethroid insecticide, undergoes oxidative metabolism leading to the formation of 4'-hydroxy-bifenthrin (4'-OH-BIF) and hydrolysis leading to the formation of TFP acid in rat and human hepatic microsomes. In this study, age-dependent metabolism of bifenthrin in rats and humans were determined via the rates of formation of 4'-OH-BIF and TFP acid following incubation of bifenthrin in juvenile and adult rat (PND 15 and PND 90) and human (<5years and >18years) liver microsomes. Furthermore, in vitro hepatic intrinsic clearance (CLint) of bifenthrin was determined by substrate consumption method in a separate experiment...

NISCH syndrome is a rare autosomal recessive disease. It is characterized by scalp hypotrichosis, scarring alopecia, ichthyosis, and neonatal sclerosing cholangitis. It is caused by mutations in the CLDN1 gene encoding the claudin-1 protein, which is located at tight junctions. Fifteen cases have been reported to date and three different mutations have been identified. We report on the case of a 2-year-old boy from a consanguineous Moroccan family, presenting with NISCH syndrome and carrying the so-called Moroccan homozygous mutation (c...

We determined the hepatitis E virus (HEV) seroprevalence and detection rate in commercial swine herds in Italy's utmost pig-rich area, and assessed HEV seropositivity risk in humans as a function of occupational exposure to pigs, diet, foreign travel, medical history and hunting activities. During 2011-2014, 2700 sera from 300 swine herds were tested for anti-HEV IgG. HEV RNA was searched in 959 faecal pools from HEV-seropositive herds and in liver/bile/muscle samples from 179 pigs from HEV-positive herds. A cohort study of HEV seropositivity in swine workers (n = 149) was also performed using two comparison groups of people unexposed to swine: omnivores (n = 121) and vegetarians/vegans (n = 115)...
