Genome stability assessment of PRRS vaccine strain with new ARTIC-style sequencing protocol.

A tiling amplicon sequencing protocol was developed to analyse the genome sequence stability of the modified live PRRSV vaccine strain, Porcilis MLV. The backbone of the ARTIC-style protocol was formed by 34 individual primer pairs, which were divided into two primer pools. Primer pairs were designed to amplify 532 to 588 bp fragments of the corresponding genomic region.

Deep Sequencing of Porcine Reproductive and Respiratory Syndrome Virus ORF7: A Promising Tool for Diagnostics and Epidemiologic Surveillance.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a major concern worldwide. Control of PRRSV is a challenging task due to various factors, including the viral diversity and variability. In this study, we evaluated an amplicon library preparation protocol targeting the ORF7 region of both PRRSV species, and .

The association between white matter tract structural connectivity and information processing speed in relapsing-remitting multiple sclerosis.

Background: Information processing speed (IPS) deterioration is common in relapsing-remitting multiple sclerosis (RRMS) patients [1] and might severely affect quality of life and occupational activity. However, understanding of its neural substrate is not fully elucidated. We aimed to investigate the associations between MRI-derived metrics of neuroanatomical structures, including the tracts, and IPS.

Altered coronary artery function, arteriogenesis and endothelial YAP signaling in postnatal hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is a cardiovascular genetic disease caused largely by sarcomere protein mutations. Gaps in our understanding exist as to how maladaptive sarcomeric biophysical signals are transduced to intra- and extracellular compartments leading to HCM progression. To investigate early HCM progression, we focused on the onset of myofilament dysfunction during neonatal development and examined cardiac dynamics, coronary vascular structure and function, and mechano-transduction signaling in mice harboring a thin-filament HCM mutation.

Skeletonized mean diffusivity and neuropsychological performance in relapsing-remitting multiple sclerosis.

Background: Peak width of Skeletonized Mean Diffusivity (PSMD), as a novel marker of white matter (WM) microstructure damage, is associated with cognitive decline in several WM pathologies (i.e., small vessel disorders).

Truncation of the N-terminus of cardiac troponin I initiates adaptive remodeling of the myocardial proteosome via phosphorylation of mechano-sensitive signaling pathways.

The cardiac isoform of troponin I has a unique N-terminal extension (~ 1-30 amino acids), which contributes to the modulation of cardiac contraction and relaxation. Hearts of various species including humans produce a truncated variant of cardiac troponin I (cTnI-ND) deleting the first ~ 30 amino acids as an adaption in pathophysiological conditions. In this study, we investigated the impact of cTnI-ND chronic expression in transgenic mouse hearts compared to wildtype (WT) controls (biological n = 8 in each group).

Effects of Sarcomere Activators and Inhibitors Targeting Myosin Cross-Bridges on Ca-Activation of Mature and Immature Mouse Cardiac Myofilaments.

We tested the hypothesis that isoform shifts in sarcomeres of the immature heart modify the effect of cardiac myosin-directed sarcomere inhibitors and activators. Omecamtiv mecarbil (OM) activates tension and is in clinical trials for the treatment of adult acute and chronic heart failure. Mavacamten (Mava) inhibits tension and is in clinical trials to relieve hypercontractility and outflow obstruction in advanced genetic hypertrophic cardiomyopathy (HCM), which is often linked to mutations in sarcomeric proteins.

SWATH-MS for prospective identification of protein blood biomarkers of rtPA-associated intracranial hemorrhage in acute ischemic stroke: a pilot study.

Intravenous recombinant tissue plasminogen activator (rtPA) is, besides mechanical thrombectomy, the highest class evidence based reperfusion treatment of acute ischemic stroke (AIS). The biggest concern of the therapy is symptomatic intracranial hemorrhage (sICH), which occurs in 3-7% of all treated patients, and is associated with worse functional outcome. Finding a method of the powerful identification of patients at highest risk of sICH, in order to increase the percentage of stroke patients safely treated with rtPA, is one of the most important challenges in stroke research.

NH-Terminal Cleavage of Cardiac Troponin I Signals Adaptive Response to Cardiac Stressors.

Cardiac sarcomeres express a variant of troponin I (cTnI) that contains a unique N-terminal extension of ~30 amino acids with regulatory phosphorylation sites. The extension is important in the control of myofilament response to Ca, which contributes to the neuro-humoral regulation of the dynamics of cardiac contraction and relaxation. Hearts of various species including humans express a stress-induced truncated variant of cardiac troponin I (cTnI-ND) missing the first ~30 amino acids and functionally mimicking the phosphorylated state of cTnI.

Concomitant treatment of atrial fibrillation during mitral valve surgery.

Introduction: Surgical management of atrial fibrillation (AF) is a well-established method of preventing complications and late mortality in patients presenting with AF before mitral valve (MV) surgery. However, despite a substantial body of evidence and a Class I recommendation to apply surgical ablation (SA) concomitant to MV surgery, the utilization of SA remains low.

Methods: In this study, we sought to summarize the current trends in the SA of AF during MV surgery and update the medical community on its advantages, including perioperative mortality and morbidity, freedom from AF, as well as long-term survival and stroke rates.

Safety and Efficacy Profile of Live, Intermediate Plus Vaccine Against Infectious Bursal Disease Based on Strain G6.

Infectious bursal disease (IBD) is an acute, highly contagious, immunosuppressive disease of young chickens that causes considerable economic loss in the poultry industry worldwide. Vaccination with live attenuated vaccines is still the most important method used for the control and prevention of IBD in chickens. Here we present the results of characterization, as well as efficacy and safety testing of a live, intermediate plus vaccine against IBD based on strain G6.

Deletion of P21-activated kinase-1 induces age-dependent increased visceral adiposity and cardiac dysfunction in female mice.

It is known that there is an age-related progression in diastolic dysfunction, especially prevalent in postmenopausal women, who develop heart failure with preserved ejection fraction (HFpEF, EF > 50%). Mechanisms and therapies are poorly understood, but there are strong correlations between obesity and HFpEF. We have tested the hypothesis that P21-activated kinase-1 (PAK1) preserves cardiac function and adipose tissue homeostasis during aging in female mice.

First report of porcine parainfluenza virus 1 (species Porcine respirovirus 1) in Europe.

Porcine respirovirus 1, also known as Porcine parainfluenza virus 1 (PPIV-1) was first identified in Hong Kong in 2013, later in the USA and most recently in Chile. Here, we report the first detection of PPIV-1 outside these three regions. We screened 22 farms in Hungary by testing 15 nasal swab samples obtained from 3-week-old piglets (3 randomly chosen piglets from 5 litters in each farm).

The spatial equity principle in the administrative division of the Central European countries.

The paper generally builds on the concept of justice in social science. It attempts to interpret this concept in a geographical and particularly in a spatial context. The paper uses the concept of accessibility to define the principle of spatial equity.

Body temperature and motion: Evaluation of an online monitoring system in pigs challenged with Porcine Reproductive & Respiratory Syndrome Virus.

Highly contagious and emerging diseases cause significant losses in the pig producing industry worldwide. Rapid and exact acquisition of real-time data, like body temperature and animal movement from the production facilities would enable early disease detection and facilitate adequate response. In this study, carried out within the European Union research project RAPIDIA FIELD, we tested an online monitoring system on pigs experimentally infected with the East European subtype 3 Porcine Reproductive & Respiratory Syndrome Virus (PRRSV) strain Lena.

Vaccination of broilers against Newcastle disease in the presence of maternally derived antibodies.

Objective: The aim of this study was to evaluate the efficacy of a live attenuated vaccine against Newcastle disease in broilers with different levels of maternally derived antibodies (MDA). While vaccination remains the single most important means for controlling Newcastle disease, presence of MDA may interfere with the vaccination of young birds and decrease the efficacy of the vaccine.

Materials And Methods: Day-old chicks with variable levels of MDA (negative, low and high) were vaccinated with a live attenuated vaccine against Newcastle disease.
