Hepatitis E Virus Genotype 1 and Hepatitis A Virus Dual Infection in Pediatric Patients with a Low Socioeconomic Status from Mexico.

We aimed to detect and characterize hepatitis E virus (HEV) RNA in sera samples from a pediatric population infected with the hepatitis A virus (HAV) exhibiting acute hepatitis and to correlate the infection status with the clinical outcome.

A Review of the Current Status of Percutaneous Endovascular Arteriovenous Fistula Creation for Haemodialysis Access.

Surgical fistulas were first described over 50 years ago and have revolutionized the outlook for millions of dialysis-dependent patients. Despite many developments, results remain sub-optimal with high rates of primary failure and re-intervention to maintain patency. Surgical fistulas are known to fail in part due to intimal hyperplasia leading to stenosis, and vessel manipulation during anastomosis creation can be contributory. New technology is emerging that allows the endovascular creation of fistulas w...

Zika virus vaccines: immune response, current status, and future challenges.

Zika virus (ZIKV) is the most recent mosquito-transmitted virus to cause a global health crisis following its entrance into a naïve population in the Western Hemisphere. Once the ZIKV outbreak began investigators rapidly established small and large animal models of pathogenesis, developed a number candidate vaccines using different platforms, and defined mechanisms of protection. In this review, we characterize the adaptive immune response elicited by ZIKV infections and vaccines, the status of ongoing cli...

Minimal capsid composition of infectious human astrovirus.

Human astrovirus is an important etiological agent of acute gastroenteritis in young children. Despite advances in the characterization of the structure of the virion by cryo-electron microscopy and of capsid proteins by x-ray crystallography, the definition of the minimal polypeptide composition of infectious virus particles has been elusive. In this work we show that mature infectious particles are composed by only two proteins; VP34 that forms the core domain of the virus, and VP27 that constitutes the 3...

Segmentation of the rabies virus genome.

We established a system for the recovery of a segmented recombinant rabies virus, the virus genome RNA of which was divided into two parts: segment 1 encoding the nucleoprotein, phosphoprotein, matrix protein, and glycoprotein genes, and segment 2 encoding the large RNA-dependent RNA polymerase gene. The morphology of the segmented recombinant rabies virus was bullet-like in shape with a length of approximately 130 nm, which is shorter than the 200-nm long non-segmented recombinant rabies virus. The segme...

A novel sheet-like virus particle array is a hallmark of Zika virus infection.

Zika virus (ZIKV) is an emerging flavivirus that caused thousands of human infections in recent years. Compared to other human flaviviruses, ZIKV replication is not well understood. Using fluorescent, transmission electron, and focused ion beam-scanning electron microscopy, we examined ZIKV replication dynamics in Vero 76 cells and in the brains of infected laboratory mice. We observed the progressive development of a perinuclear flaviviral replication factory both in vitro and in vivo. In vitro, we illustr...

All Aboard! Enteric Viruses Travel Together.

Individual virus particles have long been accepted as the infectious unit during cellular infection and host-to-host transmission. In this issue of Cell Host & Microbe, Santiana et al. (2018) uncover vesicle-cloaked rotavirus and norovirus clusters in feces of infected hosts that are more infectious than free virus particles during fecal-oral transmission.

Substandard and falsified medical products are a global public health threat. A pilot survey of awareness among physicians in Sweden.

Substandard and falsified medical products are a public health threat, primarily associated with low- and middle-income countries. Today, the phenomenon also exists in high-income countries. Increased Internet access has opened a global market. Self-diagnosis and self-prescription have boosted the market for unregulated websites with access to falsified medicines.

Analysis of global stock index data during crisis period via complex network approach.

Considerable research has been done on the complex stock market, however, there is very little systematic work on the impact of crisis on global stock markets. For filling in these gaps, we propose a complex network method, which analyzes the effects of the 2008 global financial crisis on global main stock index from 2005 to 2010. Firstly, we construct three weighted networks. The physics-derived technique of minimum spanning tree is utilized to investigate the networks of three stages. Regional clustering ...

Nanoreactors: Strategies to Encapsulate Enzyme Biocatalysts in Virus-like Particles.

Enzyme-mediated biocatalysis is generally more selective and environmentally friendly and requires less energy than chemocatalysis. However, factors such as temperature, acidity and the presence of proteases can negate enzyme activity. Encapsulation in virus-like particles is one promising method to mitigate these difficulties. Encapsulation also can be used to create multi-reaction nanoreactors that increase process efficiency by isolating reaction intermediates. To successfully encapsulate enzymes, a vari...

Unveiling the RNA virosphere associated with marine microorganisms.

The study of extracellular DNA viral particles in the ocean is currently one of the most advanced fields of research in viral metagenomic analysis. However, even though the intracellular viruses of marine microorganisms might be the major source of extracellular virus particles in the ocean, the diversity of these intracellular viruses is not well understood. Here, our newly developed method, referred to herein as fragmented and primer ligated dsRNA sequencing (flds) version 2, identified considerable genet...

Defective RNA particles derived from tomato black ring virus genome interfere with the replication of parental virus.

Tomato black ring virus (TBRV) is the only member of the Nepovirus genus that is known to form defective RNA particles (D RNAs) during replication. Here, de novo generation of D RNAs was observed during prolonged passages of TBRV isolates originated from Solanum lycopersicum and Lactuca sativa in Chenopodium quinoa plants. D RNAs of about 500 nt derived by a single deletion in the RNA1 molecule and contained a portion of the 5' untranslated region and viral replicase, and almost the entire 3' non-coding r...

Seroprevalence of sapovirus in dogs using baculovirus-expressed virus-like particles.

Caliciviruses of the Sapovirus genus have been recently detected in dogs. Canine sapoviruses (SaVs) have been identified in the stools of young or juvenile animals with gastro-enteric disease at low prevalence (2.0-2.2%), but whether they may have a role as enteric pathogens and to which extent dogs are exposed to SaVs remains unclear. Here, we report the expression in a baculovirus system of virus like-particles (VLPs) of a canine SaV strain, the prototype virus Bari/4076/2007/ITA. The recombinant antigen ...

The struggle for existence in the world market ecosystem.

The global trade system can be viewed as a dynamic ecosystem in which exporters struggle for resources: the markets in which they export. We can think that the aim of an exporter is to gain the entirety of a market share (say, car imports from the United States). This is similar to the objective of an organism in its attempt to monopolize a given subset of resources in an ecosystem. In this paper, we adopt a multilayer network approach to describe this struggle. We use longitudinal, multiplex data on trade ...

Self-assembly and stabilization of hybrid cowpea chlorotic mottle virus particles under nearly physiological conditions.

Capsids of the cowpea chlorotic mottle virus (CCMV) hold great promise for use as nanocarriers in vivo. A major drawback, however, is the lack of stability of the empty wild-type virus particles under physiological conditions. Here, we report on the assembly behavior and stability under nearly-physiological conditions of protein-based block copolymers composed of the CCMV capsid protein and two hydrophobic elastin-like polypeptides. UV-vis spectrometric studies, dynamic light scattering analysis, and transm...

Human immunodeficiency virus status in malnourished children seen at Lagos.

Human immunodeficiency virus and protein energy malnutrition are still prevalent in Nigeria and the occurrence of the two conditions together confers a poor prognosis. The aim of this study was to determine the current categories of malnutrition amongst under-5 children in Lagos, document their HIV status and determine any peculiarities in the clinical features, haematological and some biochemical profile in these children.

The parts are greater than the whole: the role of semi-infectious particles in influenza A virus biology.

The influenza A virus (IAV) genome is incorporated into newly produced virions through a tightly orchestrated process that is one of the best studied examples of genome packaging by a segmented virus. Despite the remarkable selectivity and efficiency of this process, it is clear that the vast majority of IAV virions are unable to express the full set of essential viral gene products and are thus incapable of productive replication in the absence of complementation. Here, we attempt to reconcile the widespre...

A sustained antiviral host response in respiratory syncytial virus infected human nasal epithelium does not prevent progeny virus production.

Respiratory syncytial virus infection was examined using a human nasal epithelial cell model. Maximum levels of shed-virus were produced at between 3 and 5 days post-infection (dpi), and the infectivity of the shed-virus was stable up to 10 dpi. The highest levels of interferon signalling were recorded at 2dpi, and infection induced a widespread antivirus response in the nasal epithelium, involving both infected cells and non-infected cells. Although these cellular responses were associated with reduced lev...

Highly Sensitive Glycan Profiling of Hepatitis B Viral Particles and a Simple Method for Dane Particle Enrichment.

Hepatitis B virus (HBV) is a double-stranded DNA virus composed of three types of viral particles. The virions are called Dane particles and the others are non-infectious sub-viral particles (SVPs). In blood, SVPs are detected in abundance, about 1,000-10,000 fold higher than Dane particles. Dane particles are hazardous owing to their strong infectivity, unlike SVPs. Dane particles are covered with an envelope of glycoprotein called HBV surface antigen (HBsAg). HBsAg glycosylation is involved in viral parti...

HSP70 Copurifies with Zika Virus Particles.

Zika virus (ZIKV) has been identified as a cause of neurologic diseases in infants and Guillain-Barré Syndrome, and currently, no therapeutics or vaccines are approved. In this study, we sought to identify potential host proteins interacting with ZIKV particles to gain better insights into viral infectivity. Viral particles were purified through density-gradient centrifugation and subsequently, size-exclusion chromatography (SEC). Mass spectrometric analyses revealed viral envelope protein and HSP70 to c...

Prevalence and incidence of hepatitis delta in patients with chronic hepatitis B in Spain.

Hepatitis delta virus (HDV) is a defective agent that only replicates in the presence of the hepatitis B virus. Accordingly, HDV acquisition may occur as superinfection of HBsAg+ carriers or following acute dual HDV and hepatitis B virus exposure. Herein, we examined the global and incident rates of HDV infections in Spain.
