An examination of the Northern Hemisphere mid-latitude storm track interannual variability simulated by climate models-sensitivity to model resolution and coupling.

Clim Dyn 2019 4;52(7):4247-4268. Epub 2018 Aug 4.

5Department of Mathematics and Statistics, Texas A&M University-Corpus Christi, Corpus Christi, TX 78412 USA.

The model fidelity in simulating the Northern Hemisphere storm track interannual variability and the connections of this variability to the low frequency atmospheric variations and oceanic variations are examined based on the atmospheric European Centre for Medium-Range Weather Forecasts (ECMWF) model and coupled NCAR Community Climate System Model (CCSM) systems at different horizontal resolutions. The atmospheric general circulation model (AGCM) runs are forced by observed sea surface temperatures (SST) with varying atmospheric resolutions, while the coupled general circulation model (CGCM) runs have a fixed atmospheric resolution but varying oceanic resolutions. The phases, between the North Pacific (NP) and North Atlantic (NA) sectors, of the simulated hemisphere-scale Empirical Orthogonal Function (EOF) modes of the storm track fluctuations change with the model resolution, suggesting the storm track variability in NP and NA basins are largely independent.

High-Frequency Variability of Small-Particle Carbon Export Flux in the Northeast Atlantic.

Global Biogeochem Cycles 2018 Dec 18;32(12):1803-1814. Epub 2018 Dec 18.

National Oceanography Centre Southampton UK.

The biological carbon pump exports carbon fixed by photosynthesis out of the surface ocean and transfers it to the deep, mostly in the form of sinking particles. Despite the importance of the pump in regulating the air-sea CO balance, the magnitude of global carbon export remains unclear, as do its controlling mechanisms. A possible sinking flux of carbon to the mesopelagic zone may be via the mixed-layer pump: a seasonal net detrainment of particulate organic carbon (POC)-rich surface waters, caused by sequential deepening and shoaling of the mixed layer.

The role of aerosols and greenhouse gases in Sahel drought and recovery.

Clim Change 2019 7;152(3):449-466. Epub 2018 Dec 7.

2Lamont-Doherty Earth Observatory, Columbia University, 61 Route 9W, Palisades, NY 10964 USA.

We exploit the multi-model ensemble produced by phase 5 of the Coupled Model Intercomparison Project (CMIP5) to synthesize current understanding of external forcing of Sahel rainfall change, past and future, through the lens of oceanic influence. The CMIP5 multi-model mean simulates the twentieth century evolution of Sahel rainfall, including the mid-century decline toward the driest years in the early 1980s and the partial recovery since. We exploit a physical argument linking anthropogenic emissions to the change in the temperature of the sub-tropical North Atlantic Ocean relative to the global tropical oceans to demonstrate indirect attribution of late twentieth century Sahel drought to the unique combination of aerosols and greenhouse gases that characterized the post-World War II period.

Mind the gap: observation windows to define periods of event ascertainment as a quality control method for longitudinal electronic health record data.

Ann Epidemiol 2019 Mar 4. Epub 2019 Mar 4.

Johns Hopkins University, Baltimore, MD.

Purpose: Use of electronic health records (EHRs) in health research may lead to the false assumption of complete event ascertainment. We estimated "observation windows" (OWs), defined as periods within which the assumption of complete ascertainment of events is more likely to hold, as a quality control approach to reducing the likelihood of this false assumption. We demonstrated the impact of OWs on estimating the rates of type II diabetes mellitus (diabetes) from HIV clinical cohorts. Read More

Distribution and Phylogeny of Erythrocytic Necrosis Virus (ENV) in Salmon Suggests Marine Origin.

Viruses 2019 Apr 18;11(4). Epub 2019 Apr 18.

Department of Earth, Ocean and Atmospheric Sciences, University of British Columbia, 2207 Main Mall, Vancouver, BC V6T 1Z4, Canada.

Viral erythrocytic necrosis (VEN) affects over 20 species of marine and anadromous fishes in the North Atlantic and North Pacific Oceans. However, the distribution and strain variation of its viral causative agent, erythrocytic necrosis virus (ENV), has not been well characterized within Pacific salmon. Here, metatranscriptomic sequencing of Chinook salmon revealed that ENV infecting salmon was closely related to ENV from Pacific herring, with inferred amino-acid sequences from Chinook salmon being 99% identical to those reported for herring.

A New Neural Pathway from the Ventral Striatum to the Nucleus Basalis of Meynert with Functional Implication to Learning and Memory.

Mol Neurobiol 2019 Apr 18. Epub 2019 Apr 18.

Department of Biomedical Science, Charles E. Schmidt College of Medicine, Florida Atlantic University, 777 Glades Road, Boca Raton, FL, 33431, USA.

The cholinergic neurons in the nucleus basalis of Meynert (NBM) are among the first group of neurons known to become degenerated in Alzheimer's disease, and thus the NBM is proposed to be involved in learning and memory. The marginal division (MrD) of the striatum is a newly discovered subdivision at the ventromedial border of the mammalian striatum and is considered to be one part of the ventral striatum involved in learning and memory. The present study provided evidence to support the hypothesis that the MrD and the NBM were structurally connected at cellular and subcellular levels with functional implications in learning and memory.

Highly polymorphic mitochondrial DNA and deceiving haplotypic differentiation: implications for assessing population genetic differentiation and connectivity.

BMC Evol Biol 2019 Apr 18;19(1):92. Epub 2019 Apr 18.

Royal Belgian Institute of Natural Sciences, Rue Vautier 29, B-1000, Brussels, Belgium.

Background: Hyperdiverse mtDNA with more than 5% of variable synonymous nucleotide sites can lead to erroneous interpretations of population genetic differentiation patterns and parameters (φ, D). We illustrate this by using hyperdiverse mtDNA markers to infer population genetic differentiation and connectivity in Melarhaphe neritoides, a NE Atlantic (NEA) gastropod with a high dispersal potential. We also provide a recent literature example of how mtDNA hyperdiversity may have misguided the interpretation of genetic connectivity in the crab Opecarcinus hypostegus. Read More

Closely-related Photobacterium strains comprise the majority of bacteria in the gut of migrating Atlantic cod (Gadus morhua).

Microbiome 2019 Apr 17;7(1):64. Epub 2019 Apr 17.

Department of Chemistry and the Center for Bioinformatics (SfB), Faculty of Science and Technology, UiT The Arctic University of Norway, N-9037, Tromsø, Norway.

Background: The population of Atlantic cod (Gadus morhua), also known as Northeast Arctic cod, migrating Atlantic cod, or simply "skrei," lives mainly in the Barents Sea and Svalbard waters and migrates in annual cycles to the Norwegian coast in order to spawn eggs during late winter. It is the world's largest population of Atlantic cod, and the population is distinct from the Norwegian coastal cod (or "fjord" cod). Despite the biological, economic, and cultural importance of migrating Atlantic cod, current knowledge on the associated microbiota is very limited. Read More

On the occurrence and ecology of Glaucus atlanticus Forster, 1777 (Mollusca: Nudibranchia) along the Southwestern Atlantic coast.

An Acad Bras Cienc 2019 8;91(1):e20180154. Epub 2019 Apr 8.

Laboratório de Ecologia do Zooplâncton, Instituto de Oceanografia, Universidade Federal do Rio Grande/FURG, Av. Itália, Km 8, Campus Carreiros, 96203-900, Rio Grande, RS, Brazil.

Unlike the majority of the nudibranchs, Glaucidae lives adrift at the sea surface within Tropical and Subtropical ocean basins, feeding on cnidarians or using them to attach their egg strings as a reproductive strategy. The latitudinal distribution of Glaucus atlanticus throughout the Brazilian Province is influenced by the Brazil current and, in its austral limit, by seasonal shifts in the Subtropical Convergence Zone (especially under the influence of ENSO El Niño events). Once over the shelf, seasonal wind patterns and meteorological events can force a passive displacement of the species towards the shore. Read More

Reproductive aspects of the semi-aquatic snake Erythrolamprus miliaris (Dipsadidae: Xenodontini) in the state of Rio de Janeiro, southeastern Brazil.

An Acad Bras Cienc 2019 8;91(1):e20170657. Epub 2019 Apr 8.

Departamento de Zoologia, Instituto de Biociências, Universidade Federal do Estado do Rio de Janeiro, Avenida Pasteur, 458, Urca, 22290-255 Rio de Janeiro, RJ, Brazil.

We analyzed some aspects of reproduction and sexual dimorphism of the semi-aquatic dipsadid snake Erythrolamprus miliaris in the state of Rio de Janeiro, southeastern Brazil. We detected sexual dimorphism in body size (snout-vent length), with females averaging larger than males, but no sexual dimorphism in the relative length of the tail. Oviductal eggs and secondary follicles were found in all seasons, suggesting that female reproductive cycles are continuous, in spite of the tropical seasonal climate in the region. Read More

A new approach to generalizing riparian water and air quality function across regions.

Environ Monit Assess 2019 Apr 16;191(5):282. Epub 2019 Apr 16.

Department of Natural Resources, University of Rhode Island, Kingston, RI, 02881, USA.

There is growing interest in generalizing the impact of hydrogeomorphology and weather variables on riparian functions. Here, we used RZ-TRADEOFF to estimate nitrogen, phosphorus, water table (WT) depth, and greenhouse gas (GHG: NO, CO, CH) functions for 80 riparian zones typical of the North American Midwest, Northeast (including Southern Ontario, Canada), and Mid-Atlantic. Sensitivity to weather perturbations was calculated for temperature and precipitation-dependent functions (CO, phosphate concentration, and water table), and multivariate statistical analysis on model outputs was conducted to determine trade-offs between riparian functions.

Fitness of animals for transport to slaughter.

Can Vet J 2019 Apr;60(4):423-429

Sir James Dunn Animal Welfare Centre, Department of Health Management, Atlantic Veterinary College, University of Prince Edward Island, Charlottetown, Prince Edward Island C1A 4P3.

Fitness for transport is an important factor affecting the potential for suffering during animal transportation. Examination of Canadian condemnation statistics, surveys of animals transported to slaughter, and legal case studies show that current guidelines and regulations do not always ensure that only fit animals are transported. Consideration of the pathophysiological implications of ill-health and injury on an animal's response to the potential physical and physiological challenges that can occur during transportation can assist in identifying the welfare implications of transporting compromised animals.

Selection for feed efficiency in Atlantic salmon using individual indicator traits based on stable isotope profiling.

Genet Sel Evol 2019 Apr 15;51(1):13. Epub 2019 Apr 15.

Department of Animal and Aquacultural Sciences, Faculty of Biosciences, Norwegian University of Life Sciences, Post Box 5003, 1433, Ås, Norway.

Background: We used stable isotope profiling (N and C) to obtain indicator phenotypes for feed efficiency in aquaculture. Our objectives were to (1) examine whether atom percent of stable isotopes of nitrogen and carbon can explain more of the variation in feed conversion ratio than growth alone, and (2) estimate the heritabilities of and genetic correlations between feed efficiency, growth and indicator traits as functions of nitrogen and carbon metabolism in various tissues. A 12-day experiment was conducted with 2281 Atlantic salmon parr, with an average initial weight of 21. Read More

Effect of age, ethnicity, sex, cognitive status and APOE genotype on amyloid load and the threshold for amyloid positivity.

Neuroimage Clin 2019 Mar 27;22:101800. Epub 2019 Mar 27.

Florida ADRC, USA; University of Florida College of Medicine, Gainesville, FL, USA.

The threshold for amyloid positivity by visual assessment on PET has been validated by comparison to amyloid load measured histopathologically and biochemically at post mortem. As such, it is now feasible to use qualitative visual assessment of amyloid positivity as an in-vivo gold standard to determine those factors which can modify the quantitative threshold for amyloid positivity. We calculated quantitative amyloid load, measured as Standardized Uptake Value Ratios (SUVRs) using [18-F]florbetaben PET scans, for 159 Hispanic and non-Hispanic participants, who had been classified clinically as Cognitively Normal (CN), Mild Cognitive Impairment (MCI) or Dementia (DEM).

Mesorhizobium atlanticum sp. nov., a new nitrogen-fixing species from soils of the Brazilian Atlantic Forest biome.

Int J Syst Evol Microbiol 2019 Apr 16. Epub 2019 Apr 16.

1​Embrapa Soja, C.P. 231, 86001-970 Londrina, Paraná, Brazil.

Biological nitrogen fixation performed by diazotrophic bacteria is a vital process for agricultural and environmental sustainability. In recent years, bacterial classification has been based on genomic data, accelerating our understanding about the diversity, and resulting in the description of several new species. In this study, four strains (CNPSo 3140, CNPSo 3235, CNPSo 3236 and CNPSo 3237) trapped by Phaseolus vulgaris and Mimosa pudica from soil samples of the Brazilian Atlantic Forest biome (Mata Atlântica) were submitted to polyphasic analysis to investigate their proper classification within the genus Mesorhizobium.

Locating Atrial Fibrillation Rotor and Focal Sources Using Iterative Navigation of Multipole Diagnostic Catheters.

Cardiovasc Eng Technol 2019 Apr 15. Epub 2019 Apr 15.

Department of Computer and Electrical Engineering, Florida Atlantic University, Boca Raton, FL, USA.

Purpose: Multi-polar diagnostic catheters are used to construct the 3D electro-anatomic mapping of the atrium during atrial fibrillation (AF) ablation procedures; however, it remains unclear how to use the electrograms recorded by these catheters to locate AF-driving sites known as focal and rotor source types. The purpose of this study is to present the first algorithm to iteratively navigate a circular multi-polar catheter to locate AF focal and rotor sources without the need to map the entire atria.

Methods: Starting from an initial location, the algorithm, which was blinded to the location and type of the AF source, iteratively advanced a Lasso catheter based on its electrogram characteristics. Read More

Comprehensive analysis of Fc-mediated IgM binding to the Plasmodium falciparum erythrocyte membrane protein 1 family in three parasite clones.

Sci Rep 2019 Apr 15;9(1):6050. Epub 2019 Apr 15.

Centre for Medical Parasitology at Department of Immunology and Microbiology, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

PfEMP1 is a family of adhesive proteins expressed on the surface of Plasmodium falciparum-infected erythrocytes (IEs), where they mediate adhesion of IEs to a range of host receptors. Efficient PfEMP1-dependent IE sequestration often depends on soluble serum proteins, including IgM. Here, we report a comprehensive investigation of which of the about 60 var gene-encoded PfEMP1 variants per parasite genome can bind IgM via the Fc part of the antibody molecule, and which of the constituent domains of those PfEMP1 are involved.

Megalithic tombs in western and northern Neolithic Europe were linked to a kindred society.

Proc Natl Acad Sci U S A 2019 Apr 15. Epub 2019 Apr 15.

Human Evolution, Department of Organismal Biology, Uppsala University, SE-752 36 Uppsala, Sweden;

Paleogenomic and archaeological studies show that Neolithic lifeways spread from the Fertile Crescent into Europe around 9000 BCE, reaching northwestern Europe by 4000 BCE. Starting around 4500 BCE, a new phenomenon of constructing megalithic monuments, particularly for funerary practices, emerged along the Atlantic façade. While it has been suggested that the emergence of megaliths was associated with the territories of farming communities, the origin and social structure of the groups that erected them has remained largely unknown.

Unlocking the Potential of Saliva-Based Test to Detect HPV-16-Driven Oropharyngeal Cancer.

Cancers (Basel) 2019 Apr 3;11(4). Epub 2019 Apr 3.

The School of Biomedical Sciences, Institute of Health and Biomedical Innovation, Queensland University of Technology and the Translational Research Institute, Queensland 4059, Australia.

The incidence of human papillomavirus (HPV)-positive oropharyngeal cancer (OPC) is rising in high-income countries, including Australia. Increasing evidence suggests that accurate HPV testing is pivotal for clinical decision making and treatment planning in these patients. Recently, the eighth edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor-node-metastasis (TNM) staging system for OPC (based on the p16INK4a (p16) status) was proposed and has been implemented.
