REVIEW
Nirupama Trehanpati, Ashish Kumar Vyas
Hepatocellular carcinoma (HCC) is the leading cause of cancer death and hepatitis B virus (HBV) infection is one of the commonest causes in Asians countries. India has the second largest pool after China for hepatitis B infected subjects. HBV clearance is T cell dependent and one of the reason for T cells hypo responsiveness is due to mass production of Tregs through activation of Notch signaling, which suppressCD4/CD8 T cells. Regulatory T cells (Tregs) are important to maintain cellular homeostasis; however during viral infection increase of Tregs is inversely proportional to HBV DNA titers...

Chronic hepatitis B (CHB) is characterized by hepatic inflammation that promotes progression to cirrhosis and predisposes to the development of hepatocellular carcinoma (HCC). Subtle inter-individual genetic variation, viral and environmental factors interact to determine the disease progression between individuals. Recently, the rs641738 Membrane Bound O-Acyltransferase Domain Containing 7 (MBOAT7) polymorphism was demonstrated to influence histological liver damage in alcoholic liver disease, nonalcoholic fatty liver disease and hepatitis C, but no data are available for CHB...

In our study, the development of amino functionalized carbon coated magnetic nanoparticles (NH2-CC-MNPs) and their usage for electrochemical detection of hybridization of nucleic acids have been aimed. Firstly, NH2-CC-MNPs were prepared by coating of pristine Fe3O4 nanoparticles with two layers via caramelization and silanization processes respectively. After the morphological characterization with scanning electron microscopy (SEM) it was seen that NH2-CC-MNPs was spherical shaped and in 28nm sized. Investigation of chemical composition with the help of scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX) and fourier transform infrared spectroscopy (FTIR) was showed incorporation of carbon and APTES to the structure of NH2-CC-MNPs...

Transient elastography quantifies the propagation of a mechanically generated shear wave within a soft tissue, which can be used to characterize the elasticity and viscosity parameters of the tissue. The aim of our study was to combine numerical simulation and clinical assessment to define a viscoelastic index of liver tissue to improve the quality of early diagnosis of liver fibrosis. This is clinically relevant, as early fibrosis is reversible. We developed an idealized two-dimensional axisymmetric finite element model of the liver to evaluate the effects of different viscoelastic values on the propagation characteristics of the shear wave...

BACKGROUND: An increasingly crowded immunization schedule threatens the completion and compliance of hepatitis B vaccinations (HepB), the primary method of hepatitis B prevention. Combination vaccines have been proposed to alleviate this problem. METHODS: Data from the 2011 National Immunization Survey Public Use File were utilized (GSK study identifier: HO-11-770) to compare HepB completion and compliance rates between 3 groups of children: those who received HepB combination vaccine, those who received non-HepB combination vaccine, and those who received HepB single-antigen vaccine only...

BACKGROUND: Various chromatin modifications, identified in large-scale epigenomic analyses, are associated with distinct phenotypes of different cells and disease phases. To improve our understanding of these variations, many computational methods have been developed to discover novel sites and cell-specific chromatin modifications. Despite the availability of existing methods, there is still room for further improvement when they are applied to resolve the histone code hypothesis. Hence, we aim to investigate the development of a computational method to provide new insights into de novo combinatorial pattern discovery of chromatin modifications to characterize epigenetic variations in distinct phenotypes of different cells...

AIMS/HYPOTHESIS: Despite the current pandemic of metabolic diseases, our understanding of the diverse nature of the development of metabolic alterations in people who eat a high-fat diet (HFD) is still poor. We recently demonstrated a cardio-metabolic adaptation in mice fed an HFD, which was characterised by a specific gut and periodontal microbiota profile. Since the severity of hepatic disease is characterised by specific microRNA (miRNA) signatures and the gut microbiota is a key driver of both hepatic disease and miRNA expression, we analysed the expression of three hepatic miRNA and studied their correlation with hepatic triacylglycerol content and gut microbiota...
