No Difference in Prevalence of Transmitted Drug Resistance between Injection Drug Users and Non-Injection Drug Users: A Cross-Sectional Study among Antiretroviral Treatment-Naïve HIV Patients.

Intervirology 2019 Apr 24:1-11. Epub 2019 Apr 24.

Guangxi Key Laboratory of AIDS Prevention and Treatment, School of Public Health, Guangxi Medical University, Nanning, China,

Objectives: The epidemiological evidence is inconsistent about whether HIV-positive injection drug users (IDUs) are at higher risk of developing antiretroviral resistance than any other HIV-positive populations. This study aims to investigate and compare transmitted drug resistance (TDR) between IDUs and non-IDUs in Lingshan County, an HIV-hit region in Guangxi, China, where IDU and heterosexual transmission were the two dominant transmission routes and roughly equally contributed to the local HIV transmission.

Methods: A cross-sectional study was conducted among newly diagnosed and antiretroviral-treatment (ART)-naïve HIV-1 patients from Lingshan County. Read More

Signatures of Majorana doublet in the Fano-Rashba interferometer.

J Phys Condens Matter 2019 Apr 24. Epub 2019 Apr 24.

College of Sciences, Northeastern University, Shenyang 110004, P.R CHINA, Shenyang, CHINA.

We theoretically study the quantum transport through a Fano-Rashba interferometer with an embedded Majorana doublet which generates at one end of the DIII-class topological superconductor. It shows that the Rasbha spin-orbit interaction in the reference arm drives the apparent and terminal-dependence spin polarizations of the electron tunneling and crossed Andreev reflection, accompanied by their opposite directions. However, spin degeneracy holds in the local Andreev reflection. Read More

Plasmonic performance of AuxAgyCu1-x-y alloys from many-body perturbation theory.

J Phys Condens Matter 2019 Apr 24. Epub 2019 Apr 24.

School of Physics, Trinity College Dublin, Dublin, IRELAND.

We present a detailed appraisal of the optical and plasmonic properties of ordered alloys of the form Au<sub>x</sub>Ag<sub>y</sub>Cu<sub>1-x-y</sub>, as predicted by means of first-principles many-body perturbation theory augmented by a semi-empirical Drude-Lorentz model. In benchmark simulations on elemental Au, Ag, and Cu, we find that the random-phase approximation (RPA) fails to accurately describe inter-band transitions when it is built upon semi-local approximate Kohn-Sham density-functional theory (KS-DFT) band-structures. We show that non-local electronic exchange-correlation interactions sufficient to correct this, particularly for the fully-filled, relatively narrow <i>d</i>-bands which contribute strongly throughout the low-energy spectral range (0-6 eV), may be modelled very expediently using band-stretching operators that imitate the effect of a perturbative G<sub>0</sub>W<sub>0</sub> self-energy correction incorporating quasiparticle mass renormalization.

Heterogeneous Occupancy and Vibrational Dynamics of Spatially Patterned Water Molecules.

J Phys Chem B 2019 Apr 24. Epub 2019 Apr 24.

We performed first principles molecular dynamics simulations of relatively dilute aqueous solutions of sulfate and thiosulfate dianions to analyze the structure, dynamics and vibrational spectral properties of water molecules around the solute, especially the spatially patterned solvent molecules in the first solvation layer and the extended layers. This study also involves the investigation of dynamics of dangling OH groups in these layers and their role in patterning the water molecules around the dianions. Structural evaluation of the systems is carried out by radial distribution functions (RDFs), number integrals (NIs) and spatial distribution functions (SDFs). Read More

Soil carbonate drives local adaptation in Arabidopsis thaliana.

Plant Cell Environ 2019 Apr 24. Epub 2019 Apr 24.

Plant Physiology Lab, Bioscience Faculty, Universidad Autónoma de Barcelona.

High soil carbonate limits crop performance especially in semi-arid or arid climates. To understand how plants adapt to such soils, we explored natural variation in tolerance to soil carbonate in small local populations (demes) of Arabidopsis thaliana growing on soils differing in carbonate content. Reciprocal field-based transplants on soils with elevated carbonate (+C) and without carbonate (-C) over several years revealed that demes native to (+C) soils showed higher fitness than those native to (-C) soils when both were grown together on carbonate-rich soil.

Mapping Europe into local climate zones.

PLoS One 2019 24;14(4):e0214474. Epub 2019 Apr 24.

School of Geography, University College Dublin, Dublin, Ireland.

Cities are major drivers of environmental change at all scales and are especially at risk from the ensuing effects, which include poor air quality, flooding and heat waves. Typically, these issues are studied on a city-by-city basis owing to the spatial complexity of built landscapes, local topography and emission patterns. However, to ensure knowledge sharing and to integrate local-scale processes with regional and global scale modelling initiatives, there is a pressing need for a world-wide database on cities that is suited for environmental studies.

Influenza vaccination in pregnancy: careful assessment confirms safety concerns for the offspring.

Authors:
Alberto Donzelli

Hum Vaccin Immunother 2019 Apr 24. Epub 2019 Apr 24.

a Fondazione Allineare Sanità e Salute , Milan , Italy ;

Valid evidence doesn't support universal influenza vaccination for pregnant women, the LTE objections are unfounded. The observational evidence is less valid than that from RCTs: important safety signals in all the RCTs require high consideration. In RCTs, influenza vaccinated women have mostly local adverse effects, while their offspring show a nonsignificant excess of deaths, and a significant excess of serious presumed/neonatal infections in the larger RCT.

Aligning product chemistry and soil context for agronomic reuse of human-derived resources.

Environ Sci Technol 2019 Apr 24. Epub 2019 Apr 24.

Recovering human-derived nutrients from sanitation systems can offset inorganic fertilizer use and improve access to agricultural nutrients in resource-limited settings, but the agronomic value of recovered products depends upon product chemistry and soil context. Products may exacerbate already-compromised soil conditions, offer benefits beyond nutrients, or have reduced efficacy depending on soil characteristics. Using global spatial modeling, we evaluate the soil suitability of seven products (wastewater, sludge, compost, urine, ammonium sulfate, ammonium struvite, potassium struvite) and integrate this information with local recovery potential of each product from sanitation systems that will need to be installed to achieve universal coverage (referred to here as "newly-installed sanitation").

Solid-State Photochromism by Molecular Assembly of Bis-o-Carboranyl Siloles.

Chemistry 2019 Apr 24. Epub 2019 Apr 24.

Korea University, Advanced Materials Chemistry, 2511 Sejong-ro, 30019, Sejong, KOREA, REPUBLIC OF.

A new type of solid-state photochromism was observed in an AB2 type molecular assembly comprising the central silole and two peripheral o-carborane units, and in this assembly, depending on the assembling positions of those units at the adjoining benzene ring, two different regioisomers were formed: Si-m-Cb and Si-p-Cb. Each isomer showed different solid-state photochromism depending on its solid-state conformation and was either in the crystalline or amorphous state. The crystals of each meta- or para-isomer, CSi-m-Cb or CSi-p-Cb, showed yellow or blue emission, and mechanically grinding those crystals into amorphous powders of ASi-m-Cb and ASi-p-Cb, switched their emissions to blue and yellow, respectively.

Structural origin of the high-performance light-emitting InGaN/AlGaN quantum disks.

Nanoscale 2019 Apr 24. Epub 2019 Apr 24.

Department of Materials Science and Engineering and Canadian Centre for Electron Microscopy, McMaster University, Main Street West, Hamilton, Ontario L8S 4M1, Canada.

Ternary III-nitride-based nanowires with highly efficient light-emitting properties are essential for a broad range of applications. By using the selective area molecular-beam epitaxy method, InGaN/AlGaN quantum disks (QDs) embedded in hexagonal GaN nanowires were successfully grown. With the help of atomic-scale-resolved transmission electron microscopy and atom probe tomography, atomic ordering and other related structural information, such as crystallography and local chemistry, have been unambiguously revealed to provide unique insights into the exceptionally strong photoluminescence enhancements.

Self-ordering of chemisorbed PTCDA molecules on Ge(001) driven by repulsive forces.

Phys Chem Chem Phys 2019 Apr 24. Epub 2019 Apr 24.

Department of Electronics Engineering and Computer Science, Fukuoka University, Fukuoka 814-0180, Japan.

Realization of future hybrid electronic devices combining organic and inorganic semiconductors requires a well-defined interface between both components. Such an interface can be formed generally by self-ordering of organic molecules on inorganic substrates, which is usually hindered by strong covalent bonds to the semiconductor surface. In this paper, the 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) molecules were unexpectedly found to form a locally self-ordered monolayer on a strongly interacting semiconductor surface of the Ge(001).

Novel Insights into the Management of Oligometastatic Prostate Cancer: A Comprehensive Review.

Eur Urol Oncol 2019 Mar 9;2(2):174-188. Epub 2018 Oct 9.

Department of Development and Regeneration, KU Leuven, Leuven, Belgium; Department of Urology, University Hospitals Leuven, Leuven, Belgium. Electronic address:

Context: The current standard of care for metastatic prostate cancer (PCa) is androgen deprivation therapy (ADT) plus either docetaxel or abiraterone. Growing evidence suggests that metastasis-directed therapy (MDT) and/or local therapy targeted to the primary tumour (ie, prostate) may be of benefit in the setting of oligometastatic disease. Several prospective studies are underway; however, until robust evidence is available to guide treatment decisions, physicians are challenged with how best to manage patients with oligometastases.

Making errors at work due to sleepiness or sleep problems is not confined to non-standard work hours: results of the 2016 Sleep Health Foundation national survey.

Chronobiol Int 2019 Apr 24:1-12. Epub 2019 Apr 24.

c School of Exercise and Nutrition Sciences, Adelaide Institute of Sleep Health , Flinders University , Australia.

Almost one-third of Australians report having made errors at work that are related to sleep issues. While there is significant literature investigating the role of sleep in workplace health and safety in shiftworking and nightwork operations, long working hours, work-family conflict, and commute times getting longer also impact day workers' sleep behaviors and opportunities. The aim of this study was to examine the relationship between sleep duration and disorders, sleep health and hygiene factors, work-related factors and errors at work in Australian workers. Read More

The use of evaluative expressions in the narratives of adolescents with a history of SLI.

Clin Linguist Phon 2019 Apr 24:1-16. Epub 2019 Apr 24.

c School of Foreign Languages , Central South University , Changsha , China.

Typically, young children diagnosed with specific language impairment (SLI; also called Developmental language disorder, DLD) have been found to show weakness in narrative development, and such weakness has been judged to be unlikely to resolve over time. However, developmental outcomes for adolescents with a prior SLI diagnosis have not been thoroughly studied. In particular, studies on the evaluative aspects of narratives of such persons are almost non-existent. Read More

Searching for the Optimized Luminescent Lanthanide Phosphor Using Heuristic Algorithms.

Inorg Chem 2019 Apr 24. Epub 2019 Apr 24.

State Key Laboratory of Rare Earth Resource Utilization, Changchun Institute of Applied Chemistry , Chinese Academy of Sciences , Changchun 130022 , China.

In this research, four heuristic algorithms (HAs), including simulated annealing (SA), improved annealing with a harmony search algorithm (HSA), particle swarm optimization (PSO), and genetic algorithm (GA), were used to optimize the luminescent intensity of phosphor. Among the four HAs, the improved algorithm HSA got better phosphors than SA (without using the known coded concentration). The PSO algorithm got gradually better results with increased generation, and the GA could find the best local phosphors with shorter time. Read More

Spin Selectivity in Photoinduced Charge Transfer Mediated by Chiral Molecules.

ACS Nano 2019 Apr 24. Epub 2019 Apr 24.

Optical control and readout of electron spin and spin currents in thin films and nanostructures have remained attractive yet challenging goals for emerging technologies designed for applications in information processing and storage. Recent advances in room-temperature spin polarization using nanometric chiral molecular assemblies suggest that chemically modified surfaces or interfaces can be used for optical spin conversion by exploiting photoinduced charge separation and injection from well-coupled organic chromophores or quantum dots. Using light to drive photoexcited charge-transfer processes mediated by molecules with central or helical chirality enables indirect measurements of spin polarization attributed to the chiral-induced spin selectivity effect, and of the efficiency of spin-dependent electron transfer relative to competitive radiative relaxation pathways.

[A tooth cone beam computer tomography image segmentation method based on the local Gaussian distribution fitting].

Sheng Wu Yi Xue Gong Cheng Xue Za Zhi 2019 Apr;36(2):291-297

School of Medical Instrument and Food Engineering, University of Shanghai for Science and Technology, Shanghai 200093,

Oral teeth image segmentation plays an important role in teeth orthodontic surgery and implant surgery. As the tooth roots are often surrounded by the alveolar, the molar's structure is complex and the inner pulp chamber usually exists in tooth, it is easy to over-segment or lead to inner edges in teeth segmentation process. In order to further improve the segmentation accuracy, a segmentation algorithm based on local Gaussian distribution fitting and edge detection is proposed to solve the above problems. Read More

Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi 2019 Apr;31(1):40-46

Shanghai Veterinary Research Institute, Chinese Academy of Agricultural Sciences; Key Laboratory of Animal Parasitology, Minis-try of Agriculture; National Reference Laboratory of Animal Schistosomiasis, Shanghai 200241, China.

This paper describes the damages caused by animal schistosomiasis and the role of animals in the transmission of schistosomiasis in China and reviews the progress of animal schistosomiasis control and the endemic status of animal schistosomiasis at various stages. Although the endemic situation of animal schistosomiasis has been effectively controlled, there are still multiple factors that affect the transmission of schistosomiasis, and there are still risks leading to reemergence or rebounding of schistosomiasis in local areas. Strengthening of schistosomiasis surveillance as well as the prevention and control effects in key areas, consolidation of schistosomiasis control achievements, resolving of key technical problems in the elimination of animal schistosomiasis and development of precise technical measures and strategies are needed to accelerate the progress towards the elimination of schistosomiasis in China.
