The multiple maternal legacy of the Late Iron Age group of Urville-Nacqueville (France, Normandy) documents a long-standing genetic contact zone in northwestern France.

PLoS One 2018 6;13(12):e0207459. Epub 2018 Dec 6.

De la Préhistoire à l'Actuel, Culture, Environnement, Anthropologie-UMR 5199, CNRS, Université de Bordeaux, Allée Geoffroy Saint-Hilaire, CS, Pessac Cedex, France.

The compilation of archaeological and genetic data for ancient European human groups has provided persuasive evidence for a complex series of migrations, population replacements and admixture until the Bronze Age. If the Bronze-to-Iron Age transition has been well documented archaeologically, ancient DNA (aDNA) remains rare for the latter period and does not precisely reflect the genetic diversity of European Celtic groups. In order to document the evolution of European communities, we analysed 45 individuals from the Late Iron Age (La Tène) Urville-Nacqueville necropolis in northwestern France, a region recognized as a major cultural contact zone between groups from both sides of the Channel.

Stress Coping Strategies in the Heart: An Integrated View.

Front Cardiovasc Med 2018 21;5:168. Epub 2018 Nov 21.

School of Human Nutrition, McGill University, Ste. Anne de Bellevue, QC, Canada.

The heart is made up of an ordered amalgam of cardiac cell types that work together to coordinate four major processes, namely energy production, electrical conductance, mechanical work, and tissue remodeling. Over the last decade, a large body of information has been amassed regarding how different cardiac cell types respond to cellular stress that affect the functionality of their elaborate intracellular membrane networks, the cellular reticular network. In the context of the heart, the manifestations of stress coping strategies likely differ depending on the coping strategy outcomes of the different cardiac cell types, and thus may underlie the development of distinct cardiac disorders.

J Toxicol Sci 2018 ;43(12):741-749

Department of Dermatology, Tohoku University Graduate School of Medicine.

In all current in vitro skin sensitisation assays, DMSO is used to dissolve water-insoluble chemicals. However, our previous study suggested the superiority of the modified IL-8 Luc assay (mIL-8 Luc), in which X-VIVO 15 is used to dissolve chemicals, over the original assay using DMSO (oIL-8 Luc). In this study, to confirm the superiority of the mIL-8 Luc, we first increased the number of chemicals examined and demonstrated the superiority of the mIL-8 Luc, in which the mIL-8 Luc provided 87.

Silver effects on silkworm, Bombyx mori.

J Toxicol Sci 2018 ;43(12):697-709

School of Food and Biological Engineering, Jiangsu University, China.

Silver nanoparticles (Ag-NPs) are known as a noble metal, and owing to their exclusive properties, their use is widespread in consumer products and they are mostly incorporated into food packaging and food contact products. The aim of this work was to evaluate the effects of direct ingestion of Ag-NPs through food to assess their toxicity effects on the growth and development of silkworms at different concentrations (1 mg·L to 100 mg·L), in addition to the examination of the distribution of Ag-NPs in the silkworm body and midgut histopathological analysis. RNA sequencing was performed to investigate the transcriptomic responses to Ag-NPs exposure. Read More

Fenestrations control resting-state block of a voltage-gated sodium channel.

Proc Natl Acad Sci U S A 2018 Dec 5. Epub 2018 Dec 5.

Department of Pharmacology, University of Washington, Seattle, WA 98195;

Potency of drug action is usually determined by binding to a specific receptor site on target proteins. In contrast to this conventional paradigm, we show here that potency of local anesthetics (LAs) and antiarrhythmic drugs (AADs) that block sodium channels is controlled by fenestrations that allow drug access to the receptor site directly from the membrane phase. Voltage-gated sodium channels initiate action potentials in nerve and cardiac muscle, where their hyperactivity causes pain and cardiac arrhythmia, respectively. Read More

Diversity of Salmonella serotypes from humans, food, domestic animals and wildlife in New South Wales, Australia.

BMC Infect Dis 2018 Dec 5;18(1):623. Epub 2018 Dec 5.

School of Veterinary Science, Faculty of Science, University of Sydney, Camperdown, New South Wales, Australia.

Background: Salmonella is an important human pathogen in Australia and annual case rates continue to increase. In addition to foodborne exposures, cases have been associated with animal and contaminated environment contact. However, routine surveillance in Australia has tended to focus on humans and food, with no reported attempts to collate and compare Salmonella data from a wider range of potential sources of exposure.

Social isolation, cognitive reserve, and cognition in older people with depression and anxiety.

Aging Ment Health 2018 Dec 6:1-10. Epub 2018 Dec 6.

a Centre for Research in Ageing and Cognitive Health (REACH) , School of Psychology, University of Exeter , Exeter , United Kingdom.

Objectives: Poor social connections may be associated with poor cognition in older people who are not experiencing mental health problems, and the trajectory of this association may be moderated by cognitive reserve. However, it is unclear whether this relationship is the same for older people with symptoms of depression and anxiety. This paper aims to explore social relationships and cognitive function in older people with depression and anxiety. Read More

Multitechnique investigation into the aqueous behavior of plasma polymers.

Biointerphases 2018 Dec 5;13(6):06E410. Epub 2018 Dec 5.

ANFF-Vic Biointerface Engineering Hub, Faculty of Science, Engineering and Technology, Swinburne University of Technology, Hawthorn, Victoria 3122, Australia.

Plasma polymers are often used in applications requiring aqueous immersion; therefore, it is important to understand how this exposure affects the physical and chemical properties of the films. Three different plasma polymer films were deposited at different distances from the electrode, and the film properties were characterized using contact angle, ellipsometry, and x-ray photoelectron spectroscopy. The film behaviors in aqueous solutions were studied via quartz crystal microbalance with dissipation (QCM-D). Read More

Temperature-Dependent Transport in Ultrathin Black Phosphorus Field-Effect Transistors.

Nano Lett 2018 Dec 5. Epub 2018 Dec 5.

This paper studies the temperature-dependent transport properties of ultrathin black phosphorus (BP). We present measurements of BP Schottky-barrier (SB) metal-oxide-semiconductor field-effect-transistors (MOSFETs) with various channel lengths, constructed from a single BP sample with nanoscale uniformity in thickness and width. The electrical characterization reveals a reversal in the temperature dependence of drain current as a function of gate voltage. Read More

Graphene Reinforced Composites as Protective Coatings for Oil and Gas Pipelines.

Nanomaterials (Basel) 2018 Dec 4;8(12). Epub 2018 Dec 4.

Department of Coatings and Polymeric Materials, North Dakota State University, Fargo, ND 58018, USA.

Corrosion and corrosion-induced damage have resulted mostly in malfunctions and sometimes even in failures of metallic structures, including oil and gas pipelines. In this study, new high-performance composite coatings were developed by incorporating nanoparticles in the polymer resins with applications to oil and gas pipelines. The graphene nanoplatelets under different concentrations were used to prepare the epoxy-based nanocomposites and were then evaluated through mechanical and electrical tests. Read More
