The present study focused on the inhibition effects and the safety evaluation of the quercetin when it was loaded into the nanoliposomes on cervical cancer in vitro and in vivo. Quercetin loaded nanoliposomes (Que-NLs) were first prepared by thin film hydration method and the characterizations of Que-NLs were measured with TEM and dynamic light scattering (DLS) techniques. Then the anti-cervical cancer efficiencies were evaluated by MTT and U14 tumor-bearing mice models in vitro and in vivo respectively. The body changes, organ index, biochemical criterions and histopathological of livers and kidneys in tumor-bearing mice were further assayed to evaluate the safety of Que-NLs...

Transplantation of bone marrow derived stem cells (BMSCs) has been reported inhibits liver fibrosis. Several in vitro studies by co-culturing BMSCs and hepatic stellate cells (HSCs) indirectly or directly in 2D models showed inhibition of HSC as the key player in liver fibrosis. In this study, we investigated direct effect of BMSCs on HSCs by co-culturing BMSCs and HSCs in 3D model as it represents the liver microenvironment with intricate cell-cell and cell-matrix interactions. Primary isolated rat HSCs and BMSCs were directly co-cultured at 1:1 ratio with hanging drop method...

BACKGROUND: The 2015 HIV outbreak in Indiana associated with prescription opioid injection coupled with rising rates of hepatitis C, especially in areas with long-standing opioid abuse, have raised concerns about prescription opioid injection. However, research on this topic is limited. We assessed trends in treatment admissions reporting injection, smoking, and inhalation abuse of prescription opioids and examined characteristics associated with non-oral routes of prescription opioid abuse in the U...

INTRODUCTION    Hepatitis C virus (HCV) is the major cause of chronic liver disease in patients with hemophilia. As liver biopsy should not be routinely used in them, possibilities of accurate assessment of the fibrosis stage have been very limited until recently. OBJECTIVES    The aim of the study was to determine the stage of liver fibrosis in HCV-infected hemophiliacs with use of non-invasive methods of fibrosis assessment and to analyze the influence of risk factors on liver fibrosis.  PATIENTS AND METHODS    The study included 71 HCV-infected patients with hemophilia and other congenital bleeding disorders...

Hepatitis C is a current pandemic liver disease caused by the hepatitis C virus (HCV) with high morbidity and mortality. Recently, the direct-acting antiviral agents (DAAs) targeting HCV NS3/4A, NS5A and NS5B have become the most effective therapies against HCV infection in the clinical treatment. Among them, the second-generation of NS3/4A inhibitors have emerged as the mainstay of the DAA therapies, which are derived from the peptide substrate of NS3/4A protease and modified with various tailor-made amino acids in order to achieve high sustained virologic response (SVR) against HCV...

Host hepatitis C virus (HCV)-specific T cell responses and the ability of the virus to escape this response are important correlates of infection outcome. Understanding this host-viral interplay has been difficult given the often asymptomatic nature of acute HCV infection. We studied a recent transmission case to determine whether adapted viral strains can be transmitted and influence the recipient's anti-HCV T cell response. The diversity of viral populations was examined using next-generation sequencing, and HCV-specific T cell interferon (IFN)-γ responses were assessed using a peptide panel representing the autologous viruses...

INTRODUCTION: The diagnostic procedure for chronic hepatitis C infection (CHC) usually combines anti-HCV antibody (HCV-Ab) and HCV-RNA measurement. Quantifying HCV core antigen (cAg) as a one-step procedure could shorten the diagnostic process. We aimed to assess the performance of cAg quantification in diagnosing CHC and how it is influenced by concomitant HIV or HBV infections. METHODS: The cAg was quantified by an automated assay (Abbott Diagnostics) in 465 HCV-Ab negative serum samples and 544 HCV-RNA positive serum samples (n = 1009) collected in patients from the Pasteur Center in Cameroon, some of whom were infected by HBV or HIV...

The accumulations of excess lipids within liver and serum are defined as non-alcoholic fatty liver disease (NAFLD) and hyperlipemia respectively. Both of them are components of metabolic syndrome that greatly threaten human health. Here, a recombinant fusion protein (SAK-HV) effectively treated NAFLD and hyperlipemia in high-fat-fed ApoE(-/-) mice, quails and rats within just 14 days. Its triglyceride and cholesterol-lowering effects were significantly better than that of atorvastatin during the observation period...

Fluorescence-mediated tomography (FMT) is a quantitative three-dimensional imaging technique for preclinical research applications. The combination with micro-computed tomography (µCT) enables improved reconstruction and analysis. The aim of this study is to assess the potential of µCT-FMT and kinetic modeling to determine elimination and retention of typical model drugs and drug delivery systems. We selected four fluorescent probes with different but well-known biodistribution and elimination routes: Indocyanine green (ICG), hydroxyapatite-binding OsteoSense (OS), biodegradable nanogels (NG) and microbubbles (MB)...

Uveal melanoma (UM) is a lethal intraocular malignancy with an average survival of only 2~8 months in patients with hepatic metastasis. Currently, there is no effective therapy for metastatic UM. Here, we reported that niclosamide, an effective repellence of tapeworm that has been approved for use in patients for approximately 50 years, exhibited strong antitumor activity in UM cells in vitro and in vivo. We showed that niclosamide potently inhibited UM cell proliferation, induced apoptosis and reduced migration and invasion...

Primary hepatocellular carcinoma (HCC) mainly develops in subjects chronically infected with hepatitis B (HBV) and C (HCV) viruses through a multistep process characterized by the accumulation of genetic alterations in the human genome. Nucleotide changes in coding regions (i.e. TP53, CTNNB1, ARID1A and ARID2) as well as in non-coding regions (i.e. TERT promoter) are considered cancer drivers for HCC development with variable frequencies in different geographic regions depending on the etiology and environmental factors...

BACKGROUND: Ghrelin is the only orexigenic hormone known to stimulate food intake and promote obesity and insulin resistance. We recently showed that plasma ghrelin is controlled by butyrylcholinesterase (BChE), which has a strong impact on feeding and weight gain. BChE knockout (KO) mice are prone to obesity on high-fat diet but hepatic BChE gene transfer rescues normal food intake and obesity resistance. However, these mice lack brain BChE and still develop hyperinsulinemia and insulin resistance, suggesting essential interactions between BChE and ghrelin within the brain...

Hepatitis C virus (HCV) is a silent epidemic affecting millions of patients and represents the leading indication for liver transplantation in the United States and worldwide. New direct-acting antiviral agents offer the potential to cure patients infected with HCV but it comes at a staggering cost. Given the recent attention to these high-priced HCV therapies and the impact treating individuals with HCV is having on drug expenditures in the United States, there may be a need to revisit drug patent laws and the options the federal government has to ensure patient access to care...

Virus neutralization (VN) responses range from narrowly focused antibodies with only homologous neutralizing activity against the virus used for infection, to antibodies that can neutralize both Type 1 and Type 2 viruses, referred to as broadly neutralizing antibody (bnAb). Even though neutralizing epitopes are likely distributed among several structural glycoproteins, this paper focuses on the ectodomain region of GP5 as a model system for investigating the role for neutralizing and non-neutralizing antibodies in protection and disease...
