Plant pathogens can play a role in the competitive interactions between plant species and have been understudied in native prairies, which are declining globally, and in Conservation Reserve Program (CRP) lands in the United States. Barley/Cereal yellow dwarf virus (B/CYDV) are among the most economically important disease-causing agents of small grain cereal crops, such as wheat, and are known to infect over 150 Poaceae species, including many of the grass species present in prairies and CRP lands. Field surveys of Poaceae species were conducted in endangered Palouse Prairie and CRP habitats of southeastern Washington and adjacent northern Idaho, USA from 2010-2012 to examine for the presence of B/CYDV among plant hosts and aphid vectors...

The styrene (St) emulsion polymerization using Aerosol MA80 as surfactant and in the presence of sodium styrene sulfonate (NaSS) was studied. The effect of NaSS content was assessed using MA80 concentrations below and at the critical micellar concentration. It was found that at the higher NaSS and MA80 contents, the number of particles (N) reaches a maximum of the order of 10(17)particles/cm(3) water, a huge value that has never been reported. In this work an explanation for this super-enhanced particle nucleation phenomenon is proposed...

Although multitasking with media has increased dramatically in recent years (Rideout, Foehr, & Roberts, 2010), the association between media multitasking and cognitive performance is poorly understood. In addition, the literature on the relationship between media multitasking and task-switching, one measure of cognitive control, has produced mixed results (Alzahabi & Becker, 2013; Minear et al., 2013; Ophir, Nass, & Wagner, 2009). Here we use an individual differences approach to investigate the relationship between media multitasking and task-switching performance by first examining the structure of task-switching and identifying the latent factors that contribute to switch costs...

Stable isotope ratios of nickel, copper, and zinc are powerful tools for elucidating the biogeochemical cycling of trace metals in the ocean. However, analytical difficulties have impeded isotopic studies of these metals. We present a simple and rapid method for simultaneous analysis of Ni, Cu, and Zn isotope ratios in seawater using NOBIAS Chelate-PA1 resin and anion exchange resin. A NOBIAS Chelate-PA1 resin column was used to quantitatively collect Ni, Cu, and Zn from seawater and thoroughly remove the seawater matrix...

Transcriptional adaptation to nitrate-dependent anabolism by Paracoccus denitrificans PD1222 was studied. A total of 74 genes were induced in cells grown with nitrate as N-source compared to ammonium, including nasTSABGHC and ntrBC genes. The nasT and nasS genes were cotranscribed, although nasT was more strongly induced by nitrate than nasS The nasABGHC genes constituted a transcriptional unit, which is preceded by a non-coding region containing hairpin structures involved in transcription termination. The nasTS and nasABGHC transcripts were detected at similar levels with nitrate or glutamate as N-source, but nasABGHC transcript was undetectable in ammonium-grown cells...

OBJECTIVE: Advanced Automatic Collision Notification (AACN) is a system on a motor vehicle that notifies a Public Safety Answering Point (PSAP), either directly or through a third party that the vehicle has had a crash. AACN systems enable earlier notification of a motor vehicle crash and provide an injury prediction that can help dispatchers and first responders make better decisions about how and where to transport the patient, thus getting the patient to definitive care sooner. The purpose of the current research is to identify the target population that could benefit from AACN, and develop a reasonable estimate range of potential lives saved with implementation of AACN within the vehicle fleet...

Cellular distribution and dynamics of mitochondria are regulated by several motor proteins and a microtubule network. In neurons, mitochondrial trafficking is crucial because of high energy needs and calcium ion buffering along axons to synapses during neurotransmission. The trafficking kinesin proteins (TRAKs) are well characterized for their role in lysosomal and mitochondrial trafficking in cells, especially neurons. Using whole exome sequencing, we identified homozygous truncating variants in TRAK1 (NM_001042646:c...

Background: A high incidence rate of esophageal cancer has been observed in the Northern part of Afghanistan, particularly among those of Uzbek-Turkmen ethnicity. However, there is a paucity of published data from which to compare the prevalence of environmental risk factors for esophageal cancer between Uzbek-Turkmen and other ethnic groups. Thus, we investigated the prevalence of environmental risk factors associated with esophageal cancer in the Northern part of Afghanistan, focusing on ethnicity differences...

OBJECTIVE: Federal regulations in the United States require vehicles to meet occupant performance requirements with unbelted test dummies. Removing the test requirements with unbelted occupants might encourage the deployment of seatbelt interlocks and allow restraint optimization to focus on belted occupants. The objective of this study is to compare the performance of restraint systems optimized for belted only occupants with those optimized for both belted and unbelted occupants using computer simulations and field crash data analyses...

BACKGROUND: Epileptic seizures (ES) lead to alterations in the blood laboratory values and reflect changes in different organ systems. Here, we review the diagnostic and prognostic value of various blood laboratory values within the context of epilepsy. METHODS: Narrative review and literature search on PubMed using the term, "seizure" and various laboratory values. RESULTS: Laboratory markers can help clinicians determine whether an unwitnessed event was more likely to be epileptic or non-epileptic...

Conductive hydrogels are a class of composite materials that usually comprise hydrated polymers and conductive materials. Practical application requires the conductive hydrogels to have various properties such as high conductivity, toughness, self-healing, facile processing ability, and so on. Although challenging to have all the above-mentioned properties, a composite material composed of polymer hydrogel with embedded Au nanoparticles (i.e., P(NaSS)/P(VBIm-Cl)/PVA@Au) was found to show the comprehensive properties above in this paper...

BACKGROUND: Mortality rates among children in motor vehicle crashes (MVCs) are typically low; however, nonfatal injuries can vary in severity by imposing differing levels of short- and long-term disability. To better discriminate the severity of nonfatal MVC injuries, a pediatric-specific disability risk (DR) metric was created. METHODS: The National Automotive Sampling System 2000 to 2011 was used to define the top 95% most common Abbreviated Injury Scale (AIS) 2+ injuries among pediatric MVC occupants...

Whiplash injury associated disorders (WAD) cause high costs for public health care. Neck pain is number 16 on the global prevalence lists for the 50 most common sequelae. It is of importance to obtain long-term data on disability and working capacity outcomes after rehabilitation. Long-term prospective data of the outcome course of whiplash are sparse. The aim of this study was to quantify improvements of pain, function/role performance, vitality, and working capacity 5 years after whiplash injury and to compare the state of health to normative values at 5 years after rehabilitation...

G protein-coupled receptors (GPCRs) regulate many animal behaviors. GPCR signaling is mediated by agonist-promoted interactions of GPCRs with heterotrimeric G proteins, GPCR kinases (GRKs), and arrestins. To further elucidate the role of GRKs in regulating GPCR-mediated behaviors, we utilized the genetic model system Caenorhabditis elegans Our studies demonstrate that grk-2 loss-of-function strains are egg laying-defective and contain low levels of serotonin (5-HT) and high levels of the 5-HT metabolite 5-hydroxyindole acetic acid (5-HIAA)...

To understand how molecules function in biological systems, new methods are required to obtain atomic resolution structures from biological material under physiological conditions. Intense femtosecond-duration pulses from X-ray free-electron lasers (XFELs) can outrun most damage processes, vastly increasing the tolerable dose before the specimen is destroyed. This in turn allows structure determination from crystals much smaller and more radiation sensitive than previously considered possible, allowing data collection from room temperature structures and avoiding structural changes due to cooling...

Advanced glycation end products (AGEs) are stable end products of the Maillard reaction and accumulate with progressing ageing and degenerative diseases. Significant amounts of AGE-modified peptides are also consumed with processed food. AGEs bind to specific receptors, especially the receptor of AGEs (RAGE). Activation of RAGE then evokes intracellular signalling, finally resulting in the activation of the NF-κB transcription factor and therefore a proinflammatory state. We here analysed, whether NF-κB is activated in short term upon feeding an AGE-modified protein in-vivo...
