Increasing the effectiveness of tyrosine kinase inhibitor (TKI) in combination with a statin in reducing liver fibrosis.

It has been shown that both nilotinib as a tyrosine kinase inhibitor, and atorvastatin as a rho-kinase inhibitor, have antifibrotic effects. Therefore, considering the relationship between these two pathways, this study aimed to investigate the effects of their co-treatment against hepatic stellate cells (HSCs) activation and liver fibrosis. For this purpose, the activation of HSCs coincided with these therapies.

The effects of black seed supplementation on cardiovascular risk factors in patients with nonalcoholic fatty liver disease: A randomized, double-blind, placebo-controlled clinical trial.

First Report of Prevalence of Blood-Borne Viruses (HBV, HCV, HIV, HTLV-1 and Parvovirus B19) Among Hemophilia Patients in Afghanistan.

Blood-borne viruses including Hepatitis B and C, HIV, HTLV-1 and parvovirus B19 are still a factor of concern, especially for hemophilia patients. Although the safety of the blood supply continues to improve worldwide, the blood supply system in Afghanistan was damaged by many years of conflict and political instability. To date, there are few studies focused on the prevalence of blood-borne viruses in hemophilia patients.

Crosstalk between chitosan and cell signaling pathways.

The field of tissue engineering (TE) experiences its most exciting time in the current decade. Recent progresses in TE have made it able to translate into clinical applications. To regenerate damaged tissues, TE uses biomaterial scaffolds to prepare a suitable backbone for tissue regeneration.

Pooled Prevalence of NS5A Resistance-Associated Substitutions in Chronic HCV Genotype 3 Infection: A Study Based on Deposited Sequences in GenBank.

Using direct-acting antiviral agents (DAAs) against hepatitis C virus (HCV) infection results in a high treatment response rate. However, several factors can significantly alter this outcome such as resistance-associated substitutions (RASs) in HCV NS5A gene. This study aimed to evaluate the prevalence of naturally occurring RASs of NS5A in HCV genotype 3 (HCV-3) sequences isolated from individuals with chronic HCV-3 infection.

Green cardamom supplementation improves serum irisin, glucose indices, and lipid profiles in overweight or obese non-alcoholic fatty liver disease patients: a double-blind randomized placebo-controlled clinical trial.

Background: Despite the reported health effects of cardamom on dyslipidemia, hepatomegaly, and fasting hyperglycemia, no human research has studied its potency in non-alcoholic fatty liver disease (NAFLD) as the hepatic part of metabolic syndrome. Our aim was determining the effects of green cardamom (GC) on serum glucose indices, lipids, and irisin level among overweight or obese NAFLD patients.

Methods: The place of participant recruitment was the polyclinic of the National Iranian Oil Company (NIOC) central hospital in Tehran.

Performance of a rapid diagnostic test for screening of hepatitis C in a real-life prison setting.

Background: Hepatitis C virus (HCV) point-of-care testing using rapid diagnostic test (RDT) is the solution for large-scale, feasible, fast and reliable screening of HCV infection.

Objectives: The aim of this study was to evaluate the diagnostic performance of HCV RDT for screening of HCV infection in a real-life prison setting.

Study Design: This study was conducted on individuals admitted and incarcerated in the Central Prison of Karaj, 2017-2018.

Mutations in Hepatitis D Virus Allow It to Escape Detection by CD8 T Cells and Evolve at the Population Level.

Background & Aims: Hepatitis D virus (HDV) superinfection in patients with hepatitis B virus (HBV) is associated with rapid progression to liver cirrhosis and hepatocellular carcinoma. Treatment options are limited, and no vaccine is available. Although HDV-specific CD8 T cells are thought to control the virus, little is known about which HDV epitopes are targeted by virus-specific CD8 T cells or why these cells ultimately fail to control the infection.

Antibody-drug conjugates (ADCs) for cancer therapy: Strategies, challenges, and successes.

Targeted delivery of therapeutic molecules into cancer cells is considered as a promising strategy to tackle cancer. Antibody-drug conjugates (ADCs), in which a monoclonal antibody (mAb) is conjugated to biologically active drugs through chemical linkers, have emerged as a promising class of anticancer treatment agents, being one of the fastest growing fields in cancer therapy. The failure of early ADCs led researchers to explore strategies to develop more effective and improved ADCs with lower levels of unconjugated mAbs and more-stable linkers between the drug and the antibody, which show improved pharmacokinetic properties, therapeutic indexes, and safety profiles.

Prevalence of hepatitis C virus NS5A resistance-associated substitutions in chronic infection with genotype 1: A pooled analysis based on deposited sequences in GenBank.

Introduction: Resistance-associated substitutions (RASs) in the NS5A gene of hepatitis C virus (HCV) has been studied as one of the predictors of response to NS5A inhibitor-containing regimens. This study aimed to evaluate the prevalence of pre-treatment naturally-occurring NS5A RASs in HCV isolates from patients with chronic HCV genotype 1 (HCV-1) infection retrieved from GenBank.

Methods: In the search procedure, the studies with published HCV-1 NS5A sequence in GenBank were screened and evaluated for inclusion in the pooled analysis.

Hepatitis C resistance to NS5A inhibitors: Is it going to be a problem?

Treatment of hepatitis C virus (HCV) infection has evolved greatly through the recent decade. The availability of direct-acting antiviral agents (DAAs) targeting the functional proteins of HCV has resulted in the introduction of DAA-based combination therapies, providing an optimal rate of treatment success. Among the DAAs, NS5A inhibitors are used in most of the introduced and approved HCV antiviral regimens.

Serum cytokines, adipokines and ferritin for non-invasive assessment of liver fibrosis in chronic liver disease: a systematic review.

Chronic liver disease (CLD) is a major health problem worldwide. Non-alcoholic fatty liver disease (NAFLD), chronic hepatitis C (CHC), chronic hepatitis B (CHB), and alcoholic liver disease (ALD) are the most common etiologies of CLD. Liver biopsy is the gold standard for assessment of liver fibrosis, however, it is an invasive method.

Acute changes in cardiac function by direct acting antiviral therapy for hepatitis C-infected patients with thalassemia.

Background: Patients with thalassemia may also have cardiac abnormalities due to congenital problems, anemia, and increased burden of iron in their myocardium. This study was designed to evaluate the effects of direct acting antiviral (DAA) therapy on the cardiac function of hepatitis C virus (HCV)-infected patients with thalassemia.

Method: HCV-infected thalassemia patients were enrolled to this prospective evaluation.

Amino Acid Substitutions within HLA-B*27-Restricted T Cell Epitopes Prevent Recognition by Hepatitis Delta Virus-Specific CD8 T Cells.

Virus-specific CD8 T cell response seems to play a significant role in the outcome of hepatitis delta virus (HDV) infection. However, the HDV-specific T cell epitope repertoire and mechanisms of CD8 T cell failure in HDV infection have been poorly characterized. We therefore aimed to characterize HDV-specific CD8 T cell epitopes and the impacts of viral mutations on immune escape.

A facile PCR-RFLP method for genotyping of ITPA rs1127354 and rs7270101 polymorphisms.

Background: Inosine triphosphate pyrophosphatase (ITPA) gene single nucleotide polymorphisms (SNPs), rs1127354 and rs7270101, may cause a functional impairment in ITPase enzyme, resulting anemia protection in patients with chronic hepatitis C virus (HCV) infection undergoing ribavirin (RBV)-dependent regimens. The main purpose of this study was to provide and validate a simple, rapid, and inexpensive polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique for genotyping of ITPA rs1127354 and rs7270101 polymorphisms in chronic HCV-infected patients.

Methods: In the current study, 100 Iranian patients with chronic hepatitis C were examined and genotyped for ITPA rs1127354 and rs7270101 gene polymorphisms.
