A porcine rotavirus (prv) monoreassortant, S-F4, which carries RNA segment 4 of the pig-pathogenic variant prv 4F in the genetic background of the pig-apathogenic variant prv 4S (G. I. Tauscher and U. Desselberger, J. Virol. 71:853-857, 1997), was found to be pathogenic in gnotobiotic piglets. This indicates that RNA segment 4 of the pig-pathogenic variant prv 4F is a major determinant of patho...

The pseudorabies virus (PRV) genes encoding the two subunits of the DNA polymerase were located on the genome by hybridization to their herpes simplex virus type 1 (HSV-1) homologs, pol and UL42, and subsequently were sequenced. Like the HSV-1 homologs, in vitro translation products of the PRV gene encoding the catalytic subunit (pol) possessed activity in the absence of the Pol accessory prote...

We have cloned and determined the nucleotide sequence of a gene, pk, that lies immediately upstream from the gene encoding glycoprotein X in the short unique region of the alphaherpesvirus, pseudorabies virus (PRV). The gene has the potential to encode a protein of 334 amino acids, and is related to gene US3 of herpes simplex virus type 1 (HSV-1), which has been shown to encode a protein kinase...

We amplified a 816-bp sequence of the UL31 gene from the pseudorabies virus (PRV) Becker strain genome. Evidence that this was the UL31 gene was confirmed by cloning and sequencing. The PRV UL31 gene encodes a putative protein of 271-amino acid residues, which was designated the UL31 protein. Bioinformatic analysis indicated that PRV UL31 contains a conserved PHA03328 domain, closely related wi...

BACKGROUND AND OBJECTIVE According to international standards, autonomic function is assessed by heart rate variability (HRV) calculated from R-R intervals obtained with an electrocardiogram (ECG). However, intra-operative movement artefacts and electrical interference may complicate R-wave detection. Pulse rate variability (PRV) derived from continuous blood pressure measurements may provide a...

A 948-bp sequence of the UL2 gene was amplified from the pseudorabies virus (PRV) Becker strain genome using polymerase chain reaction, and the gene identity was confirmed through further cloning and sequencing. Bioinformatic analysis indicated that the PRV UL2 gene encodes a putative polypeptide with 315-amino acid residues. Its encoding protein, designated UL2, has a conserved uracil-DNA glyc...

A clinical hallmark of human alphaherpesvirus infections is peripheral pain or itching. Pseudorabies virus (PRV), a broad host range alphaherpesvirus, causes violent pruritus in many different animals, but the mechanism is unknown. Previous in vitro studies have shown that infected, cultured peripheral nervous system (PNS) neurons exhibited aberrant electrical activity after PRV infection due t...

Vestibular nuclei have been identified as a uniform multifunctional structure in order to maintain physiological homeostasis, including the participation of renal sympathetic activity. In this study, the medial vestibular nuclei (MVe) of 10 adult male C57BL/6J strain mice were mapped retrograde using injections of pseudorabies virus (PRV)-614. The virus, injected into the kidney, was specifical...

This paper proposes a novel scheme for the generation of primary residual vector (PRV) for sensor or actuator fault detection and isolation (FDI) in multivariate dynamic systems. The PRV, which is used for fault detection purpose, is designed to be insensitive to process uncertainties, including model–plant mismatch (MPM) and process disturbances. To generate the PRV, we do not need a precise s...
