Evaluation of in vitro antimicrobial susceptibility of strains isolated during anthrax outbreaks in Italy from 1984 to 2017.

J Vet Sci 2018 Dec 4. Epub 2018 Dec 4.

Istituto Zooprofilattico Sperimentale della Puglia e della Basilicata, Anthrax Reference Institute of Italy, Foggia 71121, Italy.

Anthrax, caused by , is a non-contagious infectious disease that affects a wide range of animal species (primarily ruminants), as well as humans. Due to the often fatal outcome in human cases, the quick administration of definitely effective antimicrobials is crucial either as prophylaxis or for the therapy of clinical cases. In this study, a total of 110 strains, temporally, geographically and genetically different, isolated during anthrax outbreaks in Italy from 1984 to 2017, were screened for their susceptibility towards 16 clinically relevant antimicrobial agents using the broth microdilution method.

Plasmid-based gap-repair recombineered transgenes reveal a central role for introns in mutually exclusive alternative splicing in Down Syndrome Cell Adhesion Molecule exon 4.

Nucleic Acids Res 2018 Dec 12. Epub 2018 Dec 12.

School of Biosciences, College of Life and Environmental Sciences, University of Birmingham, Edgbaston, Birmingham B15 2TT, UK.

Alternative splicing is a key feature of human genes, yet studying its regulation is often complicated by large introns. The Down Syndrome Cell Adhesion Molecule (Dscam) gene from Drosophila is one of the most complex genes generating vast molecular diversity by mutually exclusive alternative splicing. To resolve how alternative splicing in Dscam is regulated, we first developed plasmid-based UAS reporter genes for the Dscam variable exon 4 cluster and show that its alternative splicing is recapitulated by GAL4-mediated expression in neurons.

In Vivo Imaging With Confirmation by Histopathology for Increased Rigor and Reproducibility in Translational Research: A Review of Examples, Options, and Resources.

ILAR J 2018 Dec 12. Epub 2018 Dec 12.

Department of Radiology, Miller Research Building Molecular Imaging Service Center, Johns Hopkins University, Baltimore, Maryland.

Preclinical noninvasive imaging can be an indispensable tool for studying animal models of disease. In vivo imaging to assess anatomical, functional, and molecular features requires verification by a comparison to the macroscopic and microscopic morphological features, since all noninvasive in vivo imaging methods have much lower resolution than standard histopathology. Comprehensive pathological evaluation of the animal model is underutilized; yet, many institutions have veterinary or human pathologists with necessary comparative pathology expertise. Read More

Widespread co-occurrence of multiple ploidy levels in fragile ferns (Cystopteris fragilis complex; Cystopteridaceae) probably stems from similar ecology of cytotypes, their efficient dispersal and inter-ploidy hybridization.

Ann Bot 2018 Dec 12. Epub 2018 Dec 12.

Department of Botany, Faculty of Science, University of South Bohemia, Branišovská, Ceské Budejovice, Czech Republic.

Background And Aims: Polyploidy has played an important role in the evolution of ferns. However, the dearth of data on cytotype diversity, cytotype distribution patterns and ecology in ferns is striking in comparison with angiosperms and prevents an assessment of whether cytotype coexistence and its mechanisms show similar patterns in both plant groups. Here, an attempt to fill this gap was made using the ploidy-variable and widely distributed Cystopteris fragilis complex. Read More

Functionally distinct assembly of vascular plants colonizing alpine cushions suggests their vulnerability to climate change.

Ann Bot 2018 Dec 12. Epub 2018 Dec 12.

Institute of Botany, The Czech Academy of Sciences, Průhonice, Czech Republic.

Background And Aims: Alpine cushion plants can initially facilitate other species during ecological succession, but later on can be negatively affected by their development, especially when beneficiaries possess traits allowing them to overrun their host. This can be reinforced by accelerated warming favouring competitively strong species over cold-adapted cushion specialists. However, little empirical research has addressed the trait-based mechanisms of these interactions. Read More

Effect modification of FADS2 polymorphisms on the association between breastfeeding and intelligence: results from a collaborative meta-analysis.

Int J Epidemiol 2018 Dec 11. Epub 2018 Dec 11.

Population Health Sciences, University of Bristol, Bristol, UK.

Background: Accumulating evidence suggests that breastfeeding benefits children's intelligence, possibly due to long-chain polyunsaturated fatty acids (LC-PUFAs) present in breast milk. Under a nutritional adequacy hypothesis, an interaction between breastfeeding and genetic variants associated with endogenous LC-PUFAs synthesis might be expected. However, the literature on this topic is controversial. Read More

Scattering characteristics of an exciton-plasmon nanohybrid made by coupling a monolayer graphene nanoflake to a carbon nanotube.

J Phys Condens Matter 2018 Dec 12. Epub 2018 Dec 12.

Advanced Computing and Simulation Laboratory, Monash University, Clayton,, Victoria 3800, Melbourne, Victoria, 3800, AUSTRALIA.

A hybrid nanostructure where a graphene nanoflake (GNF) is optically coupled to a carbon nanotube (CNT) could potentially possess enhanced sensing capabilities compared to the individual constituents whilst inheriting their high biocompatibility, favourable electrical, mechanical and spectroscopic properties. Therefore, in this paper, we investigate the scattering characteristics of an all-carbon exciton-plasmon nanohybrid which was made by coupling an elliptical GNF resonator to a semiconducting CNT gain element. We analytically model the nanohybrid as an open quantum system using cavity quantum electrodynamics. Read More

Telomeres in Interstitial Lung Disease: The Short and the Long of It.

Ann Am Thorac Soc 2018 Dec 12. Epub 2018 Dec 12.

Brigham and Women's Hospital, Medicine, Boston, Massachusetts, United States.

Telomeres are repetitive nucleotide sequences that cap linear chromosomes, thereby limiting progressive chromosomal shortening during cell replication. In conjunction with environmental factors, common single nucleotide polymorphisms and rare and ultra-rare telomere-related mutations are associated with accelerated telomere shortening resulting in organ dysfunction, including interstitial lung disease (ILD). The most common telomere-related mutation-associated ILD is idiopathic pulmonary fibrosis (IPF). Read More

The Tyrosine Kinase Inhibitor TAS-115 Attenuates Bleomycin-Induced Lung Fibrosis in Mice.

Am J Respir Cell Mol Biol 2018 Dec 12. Epub 2018 Dec 12.

University of Tokushima Graduate School, Respiratory Medicine and Rheumatology, Tokushima, Japan ;

The signaling pathways of growth factors including platelet-derived growth factor (PDGF) can be considered specific targets for overcoming the poor prognosis of idiopathic pulmonary fibrosis (IPF). Nintedanib, the recently approved multiple kinase inhibitor, has shown promising anti-fibrotic effects in IPF patients; however, its efficacy is still limited, and in some cases, treatment discontinuation is necessary due to toxicities such as gastrointestinal disorders. Therefore, more effective agents with less toxicity are still needed. Read More

Impacts and interactions of organic compounds with chlorine sanitizer in recirculated and reused produce processing water.

PLoS One 2018 12;13(12):e0208945. Epub 2018 Dec 12.

U. S. Department of Agriculture, Agricultural Research Service, Beltsville Agricultural Research Center, Environmental Microbiology and Food Safety Laboratory, Beltsville, Maryland, United States of America.

Water conservation and economics dictate that fresh produce processors reuse/recirculate the process water. However, the ensuing accumulation of organic matter in water depletes the chlorine sanitizer required for food safety. In this study, we comprehensively investigated chemical compounds that are responsible for water quality in relation to chemical oxygen demand (COD) and chlorine demand (CLD), the two most critical factors associated with water treatment and chlorine replenishment.

Gene network analysis of poplar root transcriptome in response to drought stress identifies a PtaJAZ3PtaRAP2.6-centered hierarchical network.

PLoS One 2018 12;13(12):e0208560. Epub 2018 Dec 12.

Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI, United States of America.

Using time-series transcriptomic data from poplar roots undergoing polyethylene glycol (PEG)-induced drought stress, we built a genetic network model of the involved putative molecular responses. We found that the network resembled a hierarchical structure. The highest hierarchical level in this structure is occupied by 9 genes, which we called superhubs because they were primarily connected to 18 hub genes, which are then connected to 2,934 terminal genes.

Spatial Epidemiology and Ecology Research Laboratory, Department of Geography, University of Florida, Gainesville, Florida, United States of America.

Quantitative models describing environmentally-mediated disease transmission rarely focus on the independent contribution of recruitment and the environment on the force of infection driving outbreaks. In this study we attempt to investigate the interaction between external factors and host's population dynamics in determining the outbreaks of some indirectly transmitted diseases. We first built deterministic and stochastic compartmental models based on anthrax which were parameterized using information from literature and complemented with field observations. Read More

A simple survey protocol for assessing terrestrial biodiversity in a broad range of ecosystems.

PLoS One 2018 12;13(12):e0208535. Epub 2018 Dec 12.

Department of Zoology, Institute of Ecology and Earth Sciences, University of Tartu, Vanemuise, Tartu, Estonia.

Finding standard cost-effective methods for monitoring biodiversity is challenging due to trade-offs between survey costs (including expertise), specificity, and range of applicability. These trade-offs cause a lack of comparability among datasets collected by ecologists and conservationists, which is most regrettable in taxonomically demanding work on megadiverse inconspicuous taxon groups. We have developed a site-scale survey method for diverse sessile land organisms, which can be analyzed over multiple scales and linked with ecological insights and management. Read More

Quality and quantity of leaf litter: Both are important for feeding preferences and growth of an aquatic shredder.

PLoS One 2018 12;13(12):e0208272. Epub 2018 Dec 12.

Department of Evolutionary Biology, Ecology and Environmental Sciences, Faculty of Biology, University of Barcelona, Barcelona, Spain.

The study of leaf litter as a resource for shredders has emerged as a key topic in trophic links in ecology. However, thus far, most studies have emphasized the leaf quality as one of the main determinants of shredder behaviour and growth without simultaneously considering the leaf quantity availability. Nevertheless, the combined effects of leaf quantity and quality on shredder behaviour and growth is particularly crucial to further understand how ecosystem functioning may respond to the increasing flow intermittency due to climate change.

Early-life environment and differences in costs of reproduction in a preindustrial human population.

PLoS One 2018 12;13(12):e0207236. Epub 2018 Dec 12.

Department of Biology, University of Turku, Turku, Finland.

Reproduction is predicted to trade-off with long-term maternal survival, but the survival costs often vary between individuals, cohorts and populations, limiting our understanding of this trade-off, which is central to life-history theory. One potential factor generating variation in reproductive costs is variation in developmental conditions, but the role of early-life environment in modifying the reproduction-survival trade-off has rarely been investigated. We quantified the effect of early-life environment on the trade-off between female reproduction and survival in pre-industrial humans by analysing individual-based life-history data for >80 birth cohorts collected from Finnish church records, and between-year variation in local crop yields, annual spring temperature, and infant mortality as proxies of early-life environment.

Social and ecological conditions of cranberry production and climate change attitudes in New England.

PLoS One 2018 12;13(12):e0207237. Epub 2018 Dec 12.

Earth and Environmental Sciences, Boston College, Chestnut Hill, Massachusetts, United States of America.

Cranberry growers in New England are increasingly pressured by negative effects associated with global climate change, some of which are familiar to this group (such as precipitation fluctuations and pest pressures), others that are rather new (such as warmer winters that threaten needed chill hours for the plants to bloom). The first study of this population of its kind, we use a survey, supplemented with observations and interviews, to assess Massachusetts cranberry grower attitudes towards climate change, and whether certain conditions of production might be associated with their attitudes. Our findings suggest that certain personal and ecological conditions are associated with greater worry of climate change effects, and that communal conditions of the cranberry grower social network provide some ways to cope with a warming climate.

Novel Treatment Options for the Surgical Management of Young Femoral Neck Fractures.

J Orthop Trauma 2019 Jan;33 Suppl 1:S33-S37

Orthopaedic Trauma Service, Hospital for Special Surgery, New York, NY.

In physiologically young patients with displaced femoral neck fractures, surgical treatment is aimed at achieving fracture union while preserving native hip anatomy and biomechanics. The intracapsular environment, tenuous vascular supply, and unfavorable hip biomechanics contribute to the high complication rates seen after osteosynthesis of these fractures. Conventional fixation methods for osteosynthesis of femoral neck fractures include multiple cancellous screws, fixed-angle dynamic implants, and fixed-angle length-stable constructs. Read More

Technologies for Young Femoral Neck Fracture Fixation.

J Orthop Trauma 2019 Jan;33 Suppl 1:S20-S26

Department of Orthopaedic Surgery, Wake Forest University School of Medicine, Winston-Salem, NC.

Fixation of young femoral neck fractures represents a challenge in the field of orthopaedic trauma surgery. Conventional methods, including cannulated screw and sliding hip screw constructs, have been studied and found to have similar results with regards to patient outcomes, which has made choosing an optimum fixation strategy difficult. In all of these cases, quality of reduction has been shown to be the most important factor when it comes to creating a favorable environment for fracture healing. Read More

When life-threatening, critical events occur in the operating room, the fast-paced, high-distraction atmosphere often leaves little time to think or deliberate about management options. Success depends on applying a team approach to quickly implement well-rehearsed, systematic, evidence-based assessment and treatment protocols. Mobile devices offer resources for readily accessible, easily updatable information that can be invaluable during perioperative critical events. Read More
