The muscle, liver, kidney and fat samples of 20 roe deer of both sexes originating from a hunting area in central Hungary were investigated for the presence of heavy metals such as As, Cd, Hg and Pb, and their contents were evaluated for possible health risk to consumers. Both As and Hg were found at a level below the limit of detection (< 0.5 mg/kg wet weight) in all samples. The median of the measured Cd concentrations was significantly higher in both the kidney and the liver (p = 0.0011) of bucks than of does...

RATIONALE: Hereditary hemochromatosis can be divided into HFE- and non-HFE-related based on genetic mutations in different genes. HFE-related hemochromatosis is the most common inherited genetic disease in European populations but rare in Asia-pacific region. Recently, non-HFE-related hemochromatosis has been reported in patients from the Asian countries. PATIENT CONCERNS: We report the case of a 48-year-old Chinese Han woman who presented with abnormal liver function, diabetes mellitus, hyperferritinemia, and high transferrin saturation, with severe iron overload in parenchymal cells, Kupffer cells, and periportal fibrosis on liver biopsy...

Progression of liver fibrosis in patients with hemoglobinopathies is strongly related to the severity of iron overload and the presence of chronic hepatitis C virus (HCV) infection. Effective iron chelation therapy and HCV infection eradication may prevent liver complications. The European Association for the Study of the Liver guidelines recommend interferon-free regimens for the treatment of HCV infection in patients with hemoglobinopathies. However, data regarding the use of direct-acting antiviral drugs (DAAs) in this patient population are few...

Subarctic lakes are characterised by extreme seasonal variation in light and temperature which influences growth, maturation, condition and resource use of fishes. However, our understanding of how seasonal changes affect mercury concentrations of fishes is limited. We conducted a year-round study (3 ice-covered months, 3 open-water months) with open-water inter-annual aspect (3 years: samples from August/September), focusing on total mercury (THg) concentrations and ecological characteristics of a common freshwater fish, European whitefish (Coregonus lavaretus (L...

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence...

BACKGROUND: Integrator complex subunit 6 (INTS6) was found to play a tumour suppressing role in certain types of solid tumours. In this study, we wanted to determine the expression level of INTS6 in hepatocellular carcinoma (HCC) and evaluate its clinical characteristics and mechanisms in HCC patients (Lui and Lu, European Journal of Cancer, 51:S94, 2015). METHODS: First, we used a microarray analysis to explore the mRNA expression levels in HCC and paired normal liver tissues; second, we used qRT-PCR to measure the INTS6 mRNA levels in a cohort of 50 HCC tissues and adjacent normal liver tissues; third, we used Western blot analyses to detect the INTS6 protein levels in 20 paired HCC and normal liver tissues; fourth, we used immunohistochemistry to determine the INTS6 expression levels in 70 archived paraffin-embedded HCC samples...

Florfenicol, a broad spectrum bacteriostatic antibiotic belonging to amphenicol class, is widely used in poultry and livestock for the treatment of various infections. The major metabolite of florfenicol in different animal species is florfenicol amine which is exploited as the marker residue for the determination of florfenicol. Analysis of florfenicol merely by solvent extraction cannot determine the accurate amount of the drug present in incurred tissues (muscle, liver and kidney) of treated birds, as indicated by this study...

While numerous surveys highlighted the natural co-occurrence of mycotoxins in food, data about their toxicological combined effects is still limited. This is especially the case for chronic exposure conditions, although the latter are more representative of the mycotoxin risk associated with food consumption than acute exposure. In the present study, cell viability and gene expression levels of relevant hepatocyte-specific functions were evaluated for the HepaRG human liver cell line exposed to deoxynivalenol (DON) and/or zearalenone (ZEA) during 14, 28 and 42days at three subtoxic concentrations corresponding to i) the determined average exposure dose of French adult population, ii) the tolerable daily intake established by the Joint FAO/WHO Expert Committee and iii) the maximum level permitted by the European regulation in cereals intended for direct human consumption...

Hepatitis B virus (HBV) infection is a major public health concern associated with major clinical complications, notably chronic liver disease that can progress with time to cirrhosis or even to hepatocellular carcinoma. The management of HBV-infected patients is complex and requires the close collaboration between the general practitioner and the specialist. This review presents an overview of recently published guidelines, from the European Association for the Study of the Liver, and suggests strategies for initial management and referral of HBV-infected patients for the general practitioner...

BACKGROUND: First seen as an innovation for select patients, laparoscopic liver resection (LLR) has evolved since its introduction, resulting in worldwide use. Despite this, it is still limited mainly to referral centers. The aim of this study was to evaluate a large cohort undergoing LLR from 2000 to 2015, focusing on the technical approaches, perioperative and oncologic outcomes, and evolution of practice over time. STUDY DESIGN: The demographics and indications, intraoperative, perioperative, and oncologic outcomes of 2,238 patients were evaluated...

PURPOSE OF REVIEW: To provide an insight and overview of the challenges in the diagnosis, follow-up and treatment of cystic fibrosis-related liver disease (CFLD). RECENT FINDINGS: The variable pathophysiology of CFLD complicates its diagnosis and treatment. A 'gold standard' for CFLD diagnosis is lacking. Over the past years, new techniques to diagnose features of CFLD, such as transient elastography, have been investigated. Although most of these tests confirm cystic fibrosis-related liver involvement (CFLI), they are, however, not suitable to distinguish various phenotypical presentations or predict progression to clinically relevant cirrhosis or portal hypertension...

Over the past decade, vectors derived from adeno-associated virus (AAV) have established themselves as a powerful tool for in vivo gene transfer, allowing long-lasting and safe transgene expression in a variety of human tissues. Nevertheless, clinical trials demonstrated how B and T cell immune responses directed against the AAV capsid, likely arising after natural infection with wild-type AAV, might potentially impact gene transfer safety and efficacy in patients. Seroprevalence studies have evidenced that most individuals carry anti-AAV neutralizing antibodies that can inhibit rAAV transduction of target cells following in vivo administration of vector particles...

Does imaging response predict survival in hepatocellular carcinoma (HCC)? We studied the ability of post-therapeutic imaging response to predict overall survival. Over 14 years, 948 HCC patients were treated with radioembolization. Patients with baseline metastases, vascular invasion, multifocal disease, Child-Pugh>B7 and transplanted/resected were excluded. This created our homogenous study cohort of 134 Child-Pugh≤B7 patients with solitary HCC.
