UNLABELLED By selecting pseudorabies virus (PrV) as a model virus, this study assessed the feasibility of applying viral inactivation strategies to manufacturing medicinal products from the milk of transgenic sows. The efficacy of heat, acidic/alkaline and detergent treatments was also evaluated with respect to their ability to inactivate PrV in milk samples. Experimental results indicate that ...

The transsynaptic retrograde transport of the pseudorabies virus Bartha (PRV-Bartha) strain has become an important neuroanatomical tract-tracing technique. Recently, dual viral transneuronal labeling has been introduced by employing recombinant strains of PRV-Bartha engineered to express different reporter proteins. Dual viral transsynaptic tracing has the potential of becoming an extremely po...

The lordosis reflex is a hormone-dependent behavior displayed by female rats during mating. This study used the transneuronal tracer pseudorabies virus (PRV) to investigate the CNS network that controls the lumbar epaxial muscles that produce this posture. After PRV was injected into lumbar epaxial muscles, the time course analysis of CNS viral infection showed progressively more PRV-labeled ne...

BACKGROUND Lipid rafts are major structural components in plasma membranes that play critical roles in many biological processes including virus infection. However, few reports have described the relationship between lipid rafts and porcine rotavirus (PRV) infection. In this study, we investigated whether or not the locally high concentrations (3-5 fold) of cholesterol present in lipid rafts ar...

Piscine reovirus (PRV) is a double stranded non-enveloped RNA virus detected in farmed and wild salmonids. This study examined the phylogenetic relationships among different PRV sequence types present in samples from salmonids in Western Canada and the US, including Alaska (US), British Columbia (Canada) and Washington State (US). Tissues testing positive for PRV were partially sequenced for se...

The purpose of this investigation was to assess the effects of acute hypoxia on left (LV) and right ventricular (RV) contractility in clinically stable chronic obstructive pulmonary disease (COPD) patients. Eleven male patients (mean age 52.4 +/- 12.6 years) who were diagnosed to have COPD were included into the study. All of the patients underwent left and right heart catheterization. RV contr...

A pseudorabies virus (PrV) mutant, deficient in the nonessential glycoprotein E (gE) and expressing the LacZ gene (gE- beta gal+ PrV), and its rescued virus were inoculated intranasally in mice. The median lethal dose of gE- beta gal+ PrV was similar to that of the parental Kaplan strain, but mice survived longer and did not develop symptoms of pseudorabies. In the nasal mucosa, gE- beta gal+ P...

The widely used pseudorabies virus (PRV) Bartha-K61 vaccine has played a key role in the eradication of PRV. Since late 2011, however, a disease characterized by neurologic symptoms and a high number of deaths among newborn piglets has occurred among Bartha-K61-vaccinated pigs on many farms in China. Clinical samples from pigs on 15 farms in 6 provinces were examined. The PRV gE gene was detect...

Pseudorabies virus (PRV), an alpha herpesvirus, induces significant economic losses to the swine industry and infects multiple kinds of animals. Therefore, it is great importance explore anti-PRV compounds. In this study, compounds, a library natural compounds was screened through cell-based ELISA assay, discovered that bufalin, Na+/K+-ATPase inhibitor, had robust inhibitory effect on PRV repli...

Abstract This paper presents an extension of the Predictive Runtime Verification (PRV) paradigm to consider multiple models System Under Analysis (SUA). We call this Multi-Model PRV. Typically, PRV attempts predict satisfaction or violation a property based on trace and (single) formal model SUA. However, contemporary node- component-based systems (e.g. robotic systems) may benefit from monitor...
