In recent years, hepatitis B core protein virus-like particle (HBc VLP) is an impressive biomaterial, which has attracted considerable attention due to favorable properties such as structural stability, high uptake efficiency, and biocompatibility in biomedical applications. Heretofore, only a few attempts have been made to apply it in physical, chemical, and biological therapy for cancer. In this study, a tumor-targeting RGD-HBc VLP is first fabricated through genetic engineering. For image-guided cancer phototherapy, indocyanine green (ICG) is loaded into RGD-HBc VLP via a disassembly/reassembly pathway and electrostatic attraction with high efficiency...

Chronic viral infections including those by hepatitis B (CHB) virus and hepatitis C (CHC) virus have been reported to be comorbidities of chronic spontaneous urticaria (CSU). Here, we performed the first comprehensive review of the peer-reviewed literature (Pubmed, Web of Science and Google Scholar) on the prevalence of CHB and CHC in patients with CSU and vice versa. The prevalence of CHB and CHC in CSU does not appear to be increased. Less than 5% and less than 2% of CSU patients have markers of CHB and CHC, respectively, according to most of the 32 studies reviewed...

Bornavirus infection is observed in both animals, including humans. However, bornavirus epidemiology in humans, especially in children, remains unclear. Here, we evaluated antibodies against bornaviruses in Japanese children with autism spectrum disorder (ASD) using immunofluorescence analysis, western blotting, and radio ligand assay. The prevalence of antibodies against bornavirus-specific speckles, N, and P proteins were 22%, 48%, and 33%, respectively, in the ASD children. According to our criteria, the prevalence of antibodies against bornaviruses was 7...

Receptive anal intercourse, multiple partners, condomless sex, sexually transmitted infections (STIs), and drug/alcohol addiction are familiar factors that correlate with increased human immunodeficiency virus (HIV) risk among men who have sex with men (MSM). To improve estimation to HIV acquisition, we created a composite score using questions from routine survey of 3588 MSM in Beijing, China. The HIV prevalence was 13.4%. A risk scoring tool using penalized maximum likelihood multivariable logistic regression modeling was developed, deploying backward step-down variable selection to obtain a reduced-form model...

Although interferon (IFN)‑based treatment of patients with chronic hepatitis C virus (HCV) infection is widely applied, treatment resistance is often observed in patients with advanced liver fibrosis. Given that the molecular mechanisms of IFN resistance in liver fibrosis remain elusive, the present study investigated the effects of extracellular matrix (ECM) on IFN signaling in hepatic cells. The native HuH‑7 human hepatoma cell line and HuH‑7 cells were stably transfected with full‑length HCV‑RNA fused with Renilla luciferase (OR6 cells) were cultured on ECM‑coated dishes or non‑coated plastic dishes (NDs), and treated with human IFN‑α...

Understanding the fine scale spatial distribution of births and pregnancies is crucial for informing planning decisions related to public health. This is especially important in lower income countries where infectious disease is a major concern for pregnant women and new-borns, as highlighted by the recent Zika virus epidemic. Despite this, the spatial detail of basic data on the numbers and distribution of births and pregnancies is often of a coarse resolution and difficult to obtain, with no co-ordination between countries and organisations to create one consistent set of subnational estimates...

Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20⁻34 proteins. Some virophages share protein similarity with Maverick/Polinton transposons or are considered as a provirophage, whereas about half of the protein's repertoire remain of unknown function. In this review, we aim to highlight the current understanding of the biology of virophages, as well as their interactions with giant viruses and host cells...

Bluetongue (BT) is a vector-borne disease transmitted by species of Culicoides midges (Diptera: Ceratopogonidae). Many studies have contributed to clarifying various aspects of its aetiology, epidemiology and vector dynamic; however, BT remains a disease of epidemiological and economic importance that affects ruminants worldwide. Since 2000, the Sardinia region has been the most affected area of the Mediterranean basin. The region is characterised by wide pastoral areas for sheep and represents the most likely candidate region for the study of Bluetongue virus (BTV) distribution and prevalence in Italy...

Foot-and-mouth disease (FMD) is one of the most contagious and economically important livestock diseases worldwide. Four serotypes of FMD virus (FMDV; O, A, SAT1, SAT2) circulate in Cameroon, and a trivalent inactivated vaccine against the three most common serotypes (O, A, SAT2) was recently introduced in 2014. The objective of this study was to characterize vaccine performance in cattle under natural hyperendemic conditions in the Adamawa region of Cameroon. Vaccinated cattle (n = 50) and non-vaccinated controls (n = 100) were monitored by serum and oropharyngeal fluid (OPF) sample collection through a 12-month period...

Current HIV-1 epidemic in China is featured by diverse subtypes and continual emergence of new recombinant viruses. This study identified a novel unique recombinant form (URF) JL16013 among men who has sex with men (MSM) in Jilin, China. The JL16013 virus was different from all known subtypes and set up a distinct branch on the phylogenetic tree. This virus had a CRF01_AE backbone with two subtype B' fragments and one CRF65_cpx fragment inserted into gag, pol, env and nef regions, suggesting that this novel URF might originated from the CRF01_AE, subtype B' and CRF65_cpx viruses that were co-circulating in Jilin province...

The rapid urban spread of Ebola virus in West Africa in 2014 and consequent breakdown of control measures led to a significant economic impact as well as the burden on public health and wellbeing. The US government appropriated $5.4 Billion for FY2015 and WHO proposed a $100 Million emergency fund largely to curtail the threat of future outbreaks. Using epidemiological analyses and economic modeling, we propose that the best use of these and similar funds would be to serve as global insurance against the continued threat of emerging infectious diseases...

Intrauterine infection with hepatitis B virus (HBV) has been suggested to accounting for most cases of chronic HBV infection, which cannot be blocked by combined immunoprophylaxis. The fact that the genetic background might impact the susceptibility to intrauterine infection of HBV has been identified by recent researches. A case-control study included sixty-nine HBsAg-positive mother-newborn pairs with intrauterine infection as cases compared to 138 mother-newborn pairs without intrauterine infection as controls...

A macluravirus, tentatively named alpinia oxyphylla mosaic virus (AloMV), was identified in Alpinia oxyphylla, and its complete genomic sequence determined. The positively single-stranded RNA genome is comprised of 8213 nucleotides excluding the poly (A) tail, and contains one large open reading frame encoding a polyprotein of 2,626 amino acids. Blastp search showed that the polyprotein of AloMV shared 48%~68% aa sequence identities with other reported macluraviruses. Phylogenetic analysis based on the nucleotide sequence of the polyprotein showed that AloMV, together with all other macluraviruses, clustered into the same group most closely related to cardamom mosaic virus, sharing 66...

The DECS (dsRNA isolation, exhaustive amplification, cloning and sequencing) analysis technique for viral diagnosis detected a tombusvirus in Japanese gentian not displaying severe symptoms. We tentatively named this virus "gentian virus A" (GeVA). GeVA systemically but inefficiently infected Japanese gentian without causing visible symptoms, while it led to severe symptoms in some other plants. The complete genome sequence of GeVA indicated a typical tombusvirus-like structure. Phylogenetic analysis of the deduced amino acid sequences of four tombusvirus-encoded proteins did not reveal other known tombusviruses that were closely-related to GeVA, suggesting that it is a novel tombusvirus...

Recombination occurs frequently between enteroviruses (EVs) which are classified within the same species of the Picornaviridae family. Here, using viral metagenomics, the genomes of two recombinant EV-Gs (strains EVG 01/NC_CHI/2014 and EVG 02/NC_CHI/2014) found in the feces of pigs from a swine farm in China are described. The two strains are characterized by distinct insertion of a papain-like protease gene from toroviruses classified within the Coronaviridae family. According to recent reports the site of the torovirus protease insertion was located at the 2C/3A junction region in EVG 02/NC_CHI/2014...

Hepatitis B virus (HBV) infection is a major cause of hepatic inflammation. Successful HBV clearance in patients is associated with sustained viral control by effector T cells. Compared with acute hepatitis B, chronic HBV infection is associated with the depletion of T cells, resulting in weak or absent virus‑specific T cells reactivity, which is described as 'exhaustion'. This exhaustion is characterized by impaired cytokine production and sustained expression of multiple coinhibitory molecules. Cytotoxic T lymphocyte‑associated antigen‑4 (CTLA‑4) is one of many coinhibitory molecules that can attenuate T cell activation by inhibiting costimulation and transmitting inhibitory signals to T cells...

β‑catenin/CTNNB1 is an intracellular scaffold protein that interacts with adhesion molecules (E‑cadherin/CDH1, N‑cadherin/CDH2, VE‑cadherin/CDH5 and α‑catenins), transmembrane‑type mucins (MUC1/CD227 and MUC16/CA125), signaling regulators (APC, AXIN1, AXIN2 and NHERF1/EBP50) and epigenetic or transcriptional regulators (BCL9, BCL9L, CREBBP/CBP, EP300/p300, FOXM1, MED12, SMARCA4/BRG1 and TCF/LEF). Gain‑of‑function CTTNB1 mutations are detected in bladder cancer, colorectal cancer, gastric cancer, liver cancer, lung cancer, pancreatic cancer, prostate cancer and uterine cancer, whereas loss‑of‑function CTNNB1 mutations are also detected in human cancer...

Hepatitis B virus (HBV) infection and related liver complications remain severe public health problems worldwide. Previous investigations have shown that small interfering (si)RNAs can offer an effective strategy for the treatment of chronic hepatitis B. The present study aimed to develop a novel siRNA‑delivering system of therapeutic HBV nuclear localization sequence (NLS) siRNAs using the recombinant preS1‑truncated protamine (tP) proteins. The preS1 region of the LHB was used in place of scFv to construct the recombinant preS1‑tP proteins, which were applied to deliver siRNAs targeting the HBV NLS to inhibit HBV replication and infection in HepG2...

Vaccination is increasingly being recognised as a potential tool to supplement 'stamping out' for controlling foot-and-mouth disease (FMD) outbreaks in non-endemic countries. Infectious disease simulation models provide the opportunity to determine how vaccination might be used in the face of an FMD outbreak. Previously, consistent relative benefits of specific vaccination strategies across different FMD simulation modelling platforms have been demonstrated, using a UK FMD outbreak scenario. We extended this work to assess the relative effectiveness of selected vaccination strategies in five countries: Australia, New Zealand, the USA, the UK and Canada...

The hepatitis B virus (HBV) is predominantly a hepatotropic virus but also infects cells of the lymphatic system. HBV genomes (DNA, messenger (m)RNA, covalently closed circular (ccc) DNA) and proteins have been found in extrahepatic sites such as peripheral blood mononuclear cells (PBMC), lymph nodes, spleen, bone marrow and cerebrospinal fluid. HBV entry into hepatocytes occurs by binding of the HBV preS1 surface protein to its specific receptor, the bile acid transporter, sodium taurocholate co-transporting polypeptide (NTCP)...
