Phenylpropanoids including diverse compounds, such as monolignols and hydroxycinnamic acids (HCAAs), are essential for land plants to protect them against abiotic stresses, and create physical and chemical barriers to pathogen infection. However, the production control of these compounds against to pathogens has been poorly understood. Previously we showed that a MAMP (microbe-associated molecular pattern) -responsive MAPK (mitogen-activated protein kinase) cascade (MKK4-MPK3/MPK6) comprehensively induced the expression of cinnamate/monolignol synthesis genes in rice cells...

Determining the fitness of viral genotypes has become a standard practice in virology as it is essential to evaluate their evolutionary potential. Darwinian fitness, defined as the advantage of a given genotype with respect to a reference, is a complex property that captures, in a single figure, differences in performance at every stage of viral infection. To what extent does viral fitness result from specific molecular interactions with host factors and regulatory networks during infection? Can we identify host genes in functional classes whose expression depends on viral fitness? Here, we compared the transcriptomes of tobacco plants infected with seven genotypes of tobacco etch potyvirus (TEV) that differ in fitness...

Leishmania parasites are unicellular pathogens that are transmitted to humans through the bite of infected sandflies. Most of the regulation of their gene expression occurs post-transcriptionally, and the different patterns of gene expression required throughout the parasites' life cycle are regulated at the level of translation. Here, we report the X-ray crystal structure of the Leishmania cap-binding isoform 1, LeishIF4E-1, bound to a protein fragment of previously unknown function, Leish4E-IP1, that binds tightly to LeishIF4E-1...

A study was conducted to determine the performance, egg quality, and liver lipid reserves of laying hens exposed to ranges contaminated with Ascaridia galli. Sixteen-week-old Lohmann Brown laying hens (n = 200) were divided into 4 treatments with 5 replicates containing 10 hens per pen. Hens of treatment 1 [negative control (NC)] ranged on a decontaminated area, and hens of treatments 2 (low infection) and 3 (medium infection) ranged on areas previously contaminated by hens artificially infected with 250 and 1,000 embryonated A...

Access to care for pediatric burns remains a major public health problem in the US. Telemedicine has an opportunity to improve access to care, but current models are expensive and inefficient. We have developed and pilot-tested the TeleBurn App, a novel smartphone application, to treat partial thickness burns while outpatient. The app allows the provision of expert clinical burn care directly in the patient's home through text and image messaging, video conferencing, and instructional videos. We retrospectively reviewed clinical outcomes and usability in pediatric partial thickness burn patients treated using the TeleBurn App compared to standard therapy alone...

The emergence of Arabidopsis as a model species and the availability of genetic and genomic resources have resulted in the identification and detailed characterisation of abiotic stress signalling pathways. However, this has led only to limited success in engineering abiotic stress tolerance in crops. This is because there needs to be a deeper understanding in how to combine resistances to a range of stresses with growth and productivity. The natural variation and genomic resources of Arabidopsis thaliana (Arabidopsis) is a great asset to understand the mechanisms of multiple stress tolerances...

Background: Prior studies evaluating the relationship between tumor necrosis factor-alpha inhibitors (TNFI) and infection were conducted in adults and had conflicting findings. We sought to examine the risk of serious infection associated with TNFIs compared with nonbiologic immunomodulators in children and young adults with inflammatory bowel disease (IBD) and to compare the risk among individual TNFIs. Methods: We conducted a cohort study using the Truven MarketScan Commercial Claims and Encounters database of patients age <30 years with a diagnosis of IBD who initiated treatment with a TNFI or immunomodulator (thiopurines or methotrexate) between 2009 and 2013...

Background and Aims: Prevalence of inflammatory bowel diseases (IBD) in older patients is increasing. Risk-benefit trade-offs of therapy are poorly understood in older patients, who may be at higher risk of nonIBD and/or treatment-related complications, rather than disease-related complications. We conducted a nationally representative cohort study to estimate and compare annual burden, costs, and causes for hospitalization in older versus younger patients with IBD. Methods: Using the Nationwide Readmissions Database 2013, we created a cohort of 47,402 patients with IBD who had been hospitalized at least once between January-June 2013 and followed for rehospitalization until December 2013...

Background: Tumor necrosis factor alpha (TNF-α) inhibitors are linked with increased risk of reactivation of active tuberculosis. The QuantiFERON-TB Gold In-Tube test is approved for screening latent tuberculosis infection in children and adults. There are limited data on the test performance in children on long-term treatment with TNF-α inhibitors. The objective of this study was to assess the proportion of indeterminate results for the QuantiFERON-TB Gold In-Tube in children with inflammatory bowel disease (IBD) on long-term infliximab treatment and to evaluate the range of interferon-γ responses to mitogen...

Background: Culture-independent diagnostic tests (CIDTs) are increasingly used to diagnose Campylobacter infection in the Foodborne Diseases Active Surveillance Network (FoodNet). Because CIDTs have different performance characteristics compared with culture, which has been used historically and is still used to diagnose campylobacteriosis, adjustment of cases diagnosed by CIDT is needed to compare with culture-confirmed cases for monitoring incidence trends. Methods: We identified the necessary parameters for CIDT adjustment using culture as the gold standard, and derived formulas to calculate positive predictive values (PPVs)...

Human noroviruses (HuNoVs) are a major cause of acute gastroenteritis. Many HuNoVs recognize histo-blood group antigens (HBGAs) as cellular receptors or attachment factors for infection. It was recently proposed that HuNoV recognition of HBGAs involves a cooperative, multistep binding mechanism that exploits both known and, previously, unknown glycan binding sites. In this study, binding measurements, implemented using electrospray ionization mass spectrometry (ESI-MS), were performed on homodimers of the protruding domain (P dimers) of the capsid protein of three HuNoV strains [Saga (GII...

Objective: B cell depletion, most commonly with rituximab, is an evolving therapeutic approach in SLE. Infusion reactions after rituximab are common, and may prevent re-treatment in patients who previously demonstrated beneficial response. We have used ofatumumab, a fully humanized anti-CD20 mAb, as an alternative B cell-depleting agent in patients with SLE who are rituximab-intolerant due to severe infusion reactions. Methods: A single-centre retrospective case series of 16 patients were treated with ofatumumab for SLE between 2012 and 2015...
