BACKGROUND: Viral transneuronal tracing has become a well established technology used to define the synaptic architecture of polysynaptic neural networks. NEW METHOD: In this report we define the neuroinvasive profile and reporter expression of a new recombinant of the Bartha strain of pseudorabies virus (PRV). The new recombinant, PRV-290, expresses the mTurquoise2 fluorophor and is designed to complement other isogenic recombinants of Bartha that express different reporters of infection...

BACKGROUND: The alphaherpesvirus virion host shutoff (vhs) gene, UL41, can induce degradation of host mRNAs and shut off host protein synthesis. The roles of vhs in HSV-1 and HSV-2 have been studied extensively in previous studies, however, relatively little is known about the vhs protein of PRV. METHODS: A novel method combining CRISPR/Cas9 and Gibson assembly was developed to generate UL41 null PRV variant. The properties of UL41 null PRV in vitro and in vivo were further characterized...

Olfactory ensheathing cells (OECs) are unique glia that support axon outgrowth in the olfactory system, and when used as cellular therapy after spinal cord injury, improve recovery and axon regeneration. Here we assessed the effects of combining OEC transplantation with another promising therapy, epidural electrical stimulation during a rehabilitative motor task. Sprague-Dawley rats received a mid-thoracic transection and transplantation of OECs or fibroblasts (FBs) followed by lumbar stimulation while climbing an inclined grid...

The main aim of this work was to characterise the Autonomic Nervous System (ANS) response in hyperbaric environments using electrocardiogram (ECG) and pulse-photoplethysmogram (PPG) signals. To that end, 26 subjects were introduced into a hyperbaric chamber and five stages with different atmospheric pressures (1 atm; descent to 3 and 5 atm; ascent to 3 and 1 atm) were recorded. Respiratory information was extracted from the ECG and PPG signals and a combined respiratory rate was studied. This information was also used to analyse Heart Rate Variability (HRV) and Pulse Rate Variability (PRV)...

PURPOSE: The neurological molecular mechanisms underlying the voiding dysfunction associated with nonbacterial chronic prostatitis/chronic pelvic pain syndrome remain poorly understood. In this study, we assessed whether prostate inflammation activated bladder afferent neurons, leading to bladder dysfunction, and sought to elucidate the underlying mechanisms. METHODS: Thirty male Sprague-Dawley rats were divided into 3 groups: sham-saline, formalin-injected, and capsaicin-pretreated and formalin-injected...

Remote camera-based measurement of physiology has great potential for healthcare and affective computing. Recent advances in computer vision and signal processing have enabled photoplethysmography (PPG) measurement using commercially available cameras. However, there remain challenges in recovering accurate noncontact PPG measurements in the presence of rigid head motion. When a subject is moving, their face may be turned away from one camera, be obscured by an object, or move out of the frame resulting in missing observations...

Antimicrobial peptide (Piscidin-1) is an effective natural polypeptide, which has great influence and potential on porcine epidemic diarrhea virus (PEDV) and pseudorabies virus (PRV). As an alternative antibiotic substitute, Piscidin-1 was subjected for pharmacokinetics study with three administration routes (i.v, i.m, and p.o) after a single dose of 2 mg/kg in rats and preliminary pharmacodynamics including antiviral activity in cell against PEDV and PRV. Based on 50 percent tissue culture infective dose (TCID50 ), there were about 2 and 10% virus survived ratios for Piscidin-1 against PRV and PEDV, respectively...

Purpose: Doses to small spinal cord isodose volume (such as those ranging from Dmax 0.0 cc to 0.5 cc) as well as to large volumes (such as those ranging from 0.5 cc to 3.0 cc) are critical parameters to guide safe practice of spine SBRT. We here report a mathematical formula that links the most probable dose volume limits together for common spine SBRT cases.Methods and materials: A dose ripple formula parameterized with equivalent dose radius (EDR) was derived to model spinal cord small-volume doses for a spine SBRT treatment...

Long noncoding RNAs (lncRNAs) play important roles in regulating eukaryotic genome replication and gene expression in diverse biological systems. Here, we identified lncRNAs transcribed from pseudorabies virus (PRV)-infected PK-15 cells. Based on high-throughput sequencing data, we obtained 87,263,926 and 93,947,628 clean reads from mock-infected and PRV-infected PK-15 cells, respectively. Through a normalized analytic protocol, we identified three novel viral lncRNAs. According to an analysis of differential expression between the mock-infected and PRV-infected cells, 4151 host lncRNAs were significantly upregulated and 2327 host lncRNAs were significantly downregulated in the latter group...

The functionality of pressure regulating valves (PRVs) is important for proper uniformity and efficiency of irrigation during center pivot irrigation, especially when the center pivot operates on sloping terrain. In practice, the regulated pressure at the PRV outlet is slightly influenced by its inlet pressure, the flow rate through it, and hysteresis effects. The objectives of this work were (a) to evaluate operational characteristics of PRVs based on requirements stated by ISO 10522 (1993) and (b) to model the regulated pressure as a function of inlet pressure and flow rate through the valve considering hysteresis...

Heart- and skeletal muscle inflammation (HSMI) caused by infection with Piscine orthoreovirus (PRV) is one of the most common viral diseases in farmed Atlantic salmon (Salmo salar) in Norway, and disease outbreaks have been reported in most countries with large-scale Atlantic salmon aquaculture. Currently there is no vaccine available for protection against HSMI, partly due to the lack of a cell line for efficient virus propagation. Erythrocytes are the primary target cells for PRV in vivo and a potential source for isolation of PRV particles...

Pseudorabies virus (PRV) is an alphaherpesvirus of swine. PRV has a large double-stranded DNA genome and, as the latest investigations have revealed, a very complex transcriptome. Here, we present a large RNA-Seq dataset, derived from both short- and long-read sequencing. The dataset contains 1.3 million 100 bp paired-end reads that were obtained from the Illumina random-primed libraries, as well as 10 million 50 bp single-end reads generated by the Illumina polyA-seq. The Pacific Biosciences RSII non-amplified method yielded 57,021 reads of inserts (ROIs) aligned to the viral genome, the amplified method resulted in 158,396 PRV-specific ROIs, while we obtained 12,555 ROIs using the Sequel platform...

Since late 2011, a pseudorabies virus (PRV) variant with increased virulence in old pigs had caused major disease outbreaks and great economic losses to the pig industry in China. The gene mutations that contributed to the increased virulence were unclear. To study the basis of the enhanced pathogenicity, an infectious bacterial artificial chromosome (BAC) clone consisting of the complete genome of the PRV variant was developed. Using homologous recombination and Cre/LoxP recombination, the recombinant virus rJS-2012-BAC carrying a BAC insertion downstream of the open reading frame (ORF) of gG was constructed...

Neurogenic airway inflammation in chronic cough and bronchial asthma related to gastroesophageal reflux (GER) is involved in the esophageal-bronchial reflex, but it is unclear whether this reflex is mediated by central neurons. This study aimed to investigate the regulatory effects of the dorsal vagal complex (DVC) on airway inflammation induced by the esophageal perfusion of hydrochloric acid (HCl) following the microinjection of nuclei in the DVC in guinea pigs. Airway inflammation was evaluated by measuring the extravasation of Evans blue dye (EBD) and substance P (SP) expression in the airway...

Stroke is the leading cause of adult disability in the world. In general, recovery from stroke is incomplete. Accumulating evidences have shown that focal cerebral infarction leads to dynamic trans-neuronal degeneration in non-ischemic remote brain regions, with the disruption of connections to synapsed neurons sustaining ischemic insults. Previously, we had reported that the ipsilateral striatum, thalamus degenerated in succession after permanent distal branch of middle cerebral artery occlusion (dMCAO) in Sprague-Dawley (SD) rats and cathepsin (Cath) B was activated before these relay degeneration...
