Comparison of catch per unit effort among four minnow trap models in the three-spined stickleback (Gasterosteus aculeatus) fishery
Authors: Budria Alexandre , DeFaveri Jacquelin , Merilä Juha
Published: December 2015

Minnow traps are commonly used in the stickleback (Gasterostidae) fishery, but the potential differences in catch per unit effort (CPUE) among different minnow trap models are little studied. We compared the CPUE of four different minnow trap models in field experiments conducted with three-spined sticklebacks (Gasterosteus aculeatus). Marked (up to 26 fold) differences in median CPUE among different trap models were observed. Metallic uncoated traps yielded the largest CPUE (2.8 fish/h), followed by metallic black nylon-coated traps (1.3 fish/h). Collapsible canvas traps yielded substantially lower CPUEs (black: 0.7 fish/h; red: 0.1 fish/h) than the metallic traps. Laboratory trials further revealed significant differences in escape probabilities among the different trap models. While the differences in escape probability can explain at least part of the differences in CPUE among the trap models (e.g. high escape rate and low CPUE in red canvas traps), discrepancies between model-specific CPUEs and escape rates suggests that variation in entrance rate also contributes to the differences in CPUE. In general and in accordance with earlier data on nine-spined stickleback (Pungitius pungitius) trapping, the results suggest that uncoated metallic (Gee-type) traps are superior to the other commonly used minnow trap models in stickleback fisheries.
Did Large-Scale Vaccination Drive Changes in the Circulating Rotavirus Population in Belgium?

Published: December 2015

Vaccination can place selective pressures on viral populations, leading to changes in the distribution of strains as viruses evolve to escape immunity from the vaccine. Vaccine-driven strain replacement is a major concern after nationwide rotavirus vaccine introductions. However, the distribution of the predominant rotavirus genotypes varies from year to year in the absence of vaccination, making it difficult to determine what changes can be attributed to the vaccines. To gain insight in the underlying dynamics driving changes in the rotavirus population, we fitted a hierarchy of mathematical models to national and local genotype-specific hospitalization data from Belgium, where large-scale vaccination was introduced in 2006. We estimated that natural- and vaccine-derived immunity was strongest against completely homotypic strains and weakest against fully heterotypic strains, with an intermediate immunity amongst partially heterotypic strains. The predominance of G2P[4] infections in Belgium after vaccine introduction can be explained by a combination of natural genotype fluctuations and weaker natural and vaccine-induced immunity against infection with strains heterotypic to the vaccine, in the absence of significant variation in strain-specific vaccine effectiveness against disease. However, the incidence of rotavirus gastroenteritis is predicted to remain low despite vaccine-driven changes in the distribution of genotypes.

Published: December 2015

Numerous bacteria, including pollutant-degrading bacteria can enter the viable but nonculturable state (VBNC) when they encounter harsh environmental conditions. VBNC bacteria, as a vast majority of potent microbial resource can be of great significance in environmental rehabilitation. It is necessary to study the VBNC state of pollutant-degrading bacteria under various stress conditions. The aim of this study was to determine whetherRhodococcus biphenylivoranscould enter the VBNC state under oligotrophic and low temperature conditions and to examine the changes of morphology, enzymatic activity and gene expressions that might underline such state. The obtained results indicated thatR.biphenylivoransTG9Tcould enter into the VBNC state and recover culturability under favorable environmental conditions. Results from Illumina high throughput RNA-sequencing revealed that the up-regulated genes related to ATP accumulation, protein modification, peptidoglycan biosynthesis and RNA polymerase were found in the VBNC cells and the down-regulated genes mainly encoded hypothetical protein, membrane protein and NADH dehydrogenase subunit, which render VBNC cells more tolerant to survive under inhospitable conditions. This study provides new insights into prevention and control of the VBNC state of pollutant-degrading bacteria for their better capabilities in environmental rehabilitation.

Published: December 2015

Two-dimensional MoS2 is a promising material for future nanoelectronics and optoelectronics. It has remained a great challenge to grow large-size crystalline and high surface coverage monolayer MoS2. In this work, we investigate the controllable growth of monolayer MoS2 evolving from triangular flakes to continuous thin films by optimizing the concentration of gaseous MoS2, which has been shown a both thermodynamic and kinetic growth factor. A single-crystal monolayer MoS2 larger than 300 μm was successfully grown by suppressing the nuclei density and supplying sufficient source. Furthermore, we present a facile process of transferring the centimeter scale MoS2 assisted with a copper thin film. Our results show the absence of observable residues or wrinkles after we transfer MoS2 from the growth substrates onto flat substrates using this technique, which can be further extended to transfer other two-dimensional layered materials.

Published: December 2015

Combining chemotherapy and targeted therapies has resulted in an enhanced survival in metastatic colorectal cancer (mCRC) patients. However, the result of this palliative treatment in patients with metachronous peritoneal carcinomatosis (PC) remains unknown. The current population-based study aims to investigate the use and effect of palliative systemic treatment in patients with metachronous PC of colorectal origin. Data on metachronous PC were collected between 2010 and 2011 for all patients who were diagnosed with M0 colorectal cancer between 2003 and 2008 in the Dutch Eindhoven Cancer Registry. Patient demographics and detailed data on chemotherapeutic treatment were collected and compared. Ninety-two patients with metachronous PC received chemotherapy in a palliative setting compared to 94 patients without treatment. In 36 patients, Bevacizumab was added to the treatment (39%). Overall survival was 3.4, 13 and 20.3 months in the no treatment, systemic treatment and systemic treatment + Bevacizumab respectively (P < 0.001). Male gender was a positive predictor and right sided primary tumor location a negative predictor of receiving bevacizumab. Approximately 40% of patients with metachronous PC received bevacizumab in addition to chemotherapy. Treatment with systemic chemotherapy in combination with bevacizumab may increase survival in a patients with metachronous colorectal PC.

Authors: Hu J. , Du L.-X. , Sun G.-S. , Xie H. , Misra R.D.K.
Published: December 2015

We describe here for the first time the low temperature superplasticity of nanostructured low carbon steel (microalloyed with V, N, Mn, Al, Si and Ni). Low carbon nanograined/ultrafine-grained (NG/UFG) bulk steel was processed using a combination of cold-rolling and annealing of martensite. The complex microstructure of NG/UFG ferrite and 50–80 nm cementite exhibited high thermal stability at 500 °C with low temperature elongation exceeding 100% (at less than 0.5 of the absolute melting point) as compared to the conventional fine-grained (FG) counterpart. The low temperature superplasticity is adequate to form complex components. Moreover, the low strength during hot processing is favorable for decreasing the spring back and minimize die loss.

Published: December 2015

Magnesium ions are essential to the basic metabolic processes in the human body. Previous genetic studies indicate that serum magnesium levels are highly heritable and a few genetic loci have been reported involving regulation of serum magnesium in adults. In this study, we examined if additional loci influence serum magnesium levels in children. We performed a genome-wide association study (GWAS) on 2,267 European-American children genotyped on the Illumina HumanHap550 or Quad610 arrays, sharing over 500,000 markers, as the discovery cohort and 257 European-American children genotyped on the Illumina Human OmniExpress arrays as the replication cohort. After genotype imputation, the strongest associations uncovered were with imputed SNPs residing within theFGFR2(rs1219515,P = 1.1 × 10−5) andPAPSS2(rs1969821,P = 7.2 × 10−6) loci in the discovery cohort, both of which were robustly replicated in our independent patient cohort (rs1219515,P = 3.5 × 10−3; rs1969821,P = 1.2 × 10−2). The associations at theFGFR2locus were also weakly replicated in a dataset from a previous GWAS of serum magnesium in European adults. Our results indicate thatFGFR2andPAPSS2may play an important role in the regulation of magnesium homeostasis in children of European-American ancestry.

Published: December 2015

Pade–Chebyshev approximation of Clenshaw–Lord type with method of moments is proposed for wide‐band analysis of an arbitrary‐shaped perfect electric conductor structure. Moreover, various Chebyshev polynomials, such as first, third, and fourth kinds, are used to express the singular points in the graph to display the expected result for scattering characteristics. The proposed algorithm has a wide radius of convergence due to the use of Chebyshev polynomials and improves calculation speed because Clenshaw–Lord‐type Pade approximation requires fewer sampling points than Maehly‐type Pade approximation in the derivation of the rational function. The results of the proposed method agree very well with the exact solution and reveal its possibility of obtaining more accurate solution than the asymptotic waveform evaluation technique.

Published: December 2015

Two types of narrow‐band dielectric frequency‐selective surfaces (DFSSs) have been designed at microwave frequencies. First, a DFSS showing total reflection has been analysed under guided‐mode resonance conditions, based on a single dielectric grating which is illuminated by a TM polarised two‐dimensional plane wave at Brewster‐angle incidence, presenting extremely low‐reflectance sidebands adjacent to the resonance peak. Second, a DFSS exhibiting total transmission at normal TE incidence has been designed, by superimposing the resonance condition of a dielectric grating on the classical high‐reflectance response of a periodic (band‐gap based) structure formed by alternating homogeneous dielectric layers. Finally, the oblique incidence and polarisation effects on the spectral response of the designed DFSSs have been also studied. In addition, dielectric ohmic losses and the problem of the finite size of the periodic structures have been accounted for in both structures. The obtained results have been successfully validated with the commercial software tool high frequency structure simulator.

Published: December 2015

In this study, the authors discuss in detail the implementation of all‐optical orthogonal frequency‐division multiplexing system based on discrete wavelet packet transform (DWPT) by using silicon‐on‐insulator (SOI) cascaded Mach–Zehnder interferometers (MZIs). DWPT can be used in the multiplexing and de‐multiplexing of data channels in coherent optical communication in order to improve spectral efficiency excluding a cyclic prefix. DWPT and inverse‐DWPT may be realised in an integrated‐photonic MZI platform. They demonstrated experimentally the post‐fabrication tuning of 1 × 4 cascaded MZI de‐multiplexing filters. Tuning procedures effectively overcome fabrication tolerances and meet the target transfer function of the devices. The fabrication platform represents an essential stepping‐stone toward the all‐optical realisation of DWPT‐based multiplexing.
Scalable self‐assembly process for the fabrication of sub‐millimetre three‐dimensional cylindrical tubes
Authors: Karagozler Mustafa Emre , Goldstein Seth Copen , Ricketts David S.
Published: December 2015

The analysis, simulation and experimental fabrication of three‐dimensional (3D) cylindrical tubes formed from 2D aluminium/silicon dioxide (Al/SiO2) substrates are presented. The photolithographically fabricated planar Al/SiO2 substrates bend under residual mechanical stress after release, self‐assembling into 3D cylindrical tubes. They present an analytical model that allows them to reliably predict the resulting radius of curvature of bi‐layer Al/SiO2 tubes with uniform cross‐sections, and provides an approximate solution for SiO2 substrates with patterned Al cross‐sections. Finite element analysis simulations and measurements of fabricated tubes show agreement with the model. In addition, they show through a series of batch experiments that the self‐assembly process is repeatable with proper design of the substrates.

Magnesium (Mg) plays a vital role in photosynthesis, dry matter production and carbon partitioning in sink organs. Hence, four permanent manurial experiments (20–27 years of duration) under the auspices of All India Coordinated Research Project for Dryland Agriculture (AICRPDA) network centres across diverse agro-ecological regions were carried out to examine the soil exchangeable Mg (ex-Mg), crop uptake and overall Mg balance. Groundnut (peanut), finger millet, rice–lentil sequence and post rainy sorghum were the major crops or cropping systems followed in four permanent manure experiments at Anantapuram, Bengaluru, Varanasi and Solapur, respectively. Nutrient management in all experiments involved control (no addition of nutrients), 100% organic, 100% chemical, and integration of organic and chemical. Except in the finger millet-based system, mean ex-Mg status in the entire profile was higher than the sufficiency level (1.0 cmol(+) kg–1 as a critical limit). Status of ex-Mg (cmol(+) kg–1 soil) in soil profiles was in the order: Solapur (3.80) > Varanasi (2.07) > Anantapuram (1.06) > Bengaluru (0.44). A uniform distribution of ex-Mg was observed in plots that received integrated application of organic and chemical fertilisers. In general, improved status of profile ex-Mg (cmol(+) kg–1) over the control was observed in soils under groundnut (0.19–0.78), finger millet (1.90–3.20), and post rainy sorghum (6.50–7.60, except 4.20 in 100% NPK) cropping. Overall, ex-Mg status and balance of different soil types under diverse crop production systems was influenced by several factors, some of which include soil type with varying mineralogy, particle size distribution, nutrient management strategies and rainfall. Significant positive relationships were observed between ex-Mg status and clay content (R2 = 0.94), soil pH (R2 = 0.92), cation exchange capacity (R2 = 0.98) and mean air temperature (R2 = 0.22), whereas a weak relationship was observed with rainfall (R2 = 0.01). The study gives an account of Mg balance in major Indian soil types and recommends further attention on Mg nutrition in current intensive agriculture.
Magnesium alleviates plant toxicity of aluminium and heavy metals

Published: December 2015

Magnesium (Mg) is an essential nutrient that can alleviate soilborne toxicity of many ions. This review paper critically assesses the literature on interactions and mechanisms influencing Mg alleviation of aluminium (Al) and heavy metal toxicity. Hydrated radii of Mg2+ and Al3+ are similar; therefore, these two ions compete for binding to ion transporters and other important biological molecules. In monocotyledonous species such as rice and wheat, millimolar concentrations of Mg alleviate Al toxicity, mainly by decreasing Al saturation and activity at cell wall and plasma membrane binding sites. In dicotyledonous legume species such as soybean (Glycine max), rice bean (Vigna umbellata) and broad bean (Vicia faba), micromolar concentrations of Mg may enhance biosynthesis of organic ligands and thus underpin alleviation of Al toxicity. Resistance to Al may be enhanced by increased expression of the genes coding for Mg transporters, as well as by upregulation of activity of Mg-transport proteins; intracellular Mg2+ activity may thus be increased under Al stress, which may increase the activity of H+-ATPases. In Vicia faba, Mg-related enhancement in the activity of plasma membrane H+-ATPase under Al stress was found to be due to post-translational modification (increased phosphorylation of the penultimate threonine as well as association with regulatory 14-3-3 proteins), resulting in increased resistance to Al stress. Magnesium can alleviate heavy metal stress by decreasing negative electrical potential and thus metal ion activities at the plasma membrane surface (physico-chemical competition), by enhancing activities of enzymes involved in biosynthesis of organic ligands, and by increasing vacuolar sequestration of heavy metals via increasing H+-pumping activity at the tonoplast. Future work should concentrate on characterising the role of intracellular Mg2+ homeostasis and Mg transporters in alleviating metal stress as well as in transcriptional, translational and post-translational regulation of H+-pumps and enzymes involved in biosynthesis and exudation of organic ligands.
Using Indigenist and Indigenous methodologies to connect to deeper understandings of Aboriginal and Torres Strait Islander peoples’ quality of life
Authors: Kite Elaine , Davy Carol
Published: December 2015

The lack of a common description makes measuring the concept of quality of life (QoL) a challenge. Whether QoL incorporates broader social features or is attributed to health conditions, the diverse range of descriptions applied by various disciplines has resulted in a concept that is multidimensional and vague. The variety of theoretical conceptualisations of QoL confounds and confuses even the most astute. Measuring QoL in Aboriginal and Torres Strait Islander populations is even more challenging. Instruments commonly developed and used to measure QoL are often derived from research methodologies shaped by Western cultural perspectives. Often they are simply translated for use among culturally and linguistically diverse Aboriginal and Torres Strait Islander peoples. This has implications for Aboriginal and Torres Strait Islander populations whose perceptions of health are derived from within their specific cultures, value systems and ways of knowing and being. Interconnections and relationships between themselves, their communities, their environment and the natural and spiritual worlds are complex. The way in which their QoL is currently measured indicates that very little attention is given to the diversity of Aboriginal and Torres Strait Islander peoples' beliefs or the ways in which those beliefs shape or give structure and meaning to their health and their lives. The use of Indigenist or Indigenous methodologies in defining what Aboriginal and Torres Strait Islander peoples believe gives quality to their lives is imperative. These methodologies have the potential to increase the congruency between their perceptions of QoL and instruments to measure it.
‘Most young men think you have to be naked in front of the GP’: a qualitative study of male university students’ views on barriers to sexual health
Authors: Ewert Cameron , Collyer Archibald , Temple-Smith Meredith
Published: December 2015

Background In Australia, 15- to 29-year-olds account for 75% of all sexually transmissible infection (STI) diagnoses. STI rates among young men are rising, with most diagnosed in general practice. Young men less frequently attend general practice than young women, and rarely present with sexual health issues, making it difficult for general practitioners (GPs) to offer opportunistic STI education and screening. Little is known of the barriers preventing male university students accessing general practice for sexual health care, or what would facilitate this. Methods: Semi-structured interviews were conducted with young men aged 18–24 years attending university between 2012 and 2014. Interviews were recorded, transcribed and analysed using content and thematic analysis. Results: Twenty-eight interviews of 26–50 min duration found self-imposed views of masculinity, privacy and embarrassment as key barriers to accessing GPs for sexual health care. This was compounded by poor STI knowledge and not knowing when or where to go for care. Participants, except if they were international students, acknowledged school as an important source of sexual health education. The need for sexual health education at university was identified. While the Internet was a popular source, there were mixed views on the benefits of social media and text messaging for sexual health promotion. Conclusions: Current expectations of young male university students to seek sexual health care or acquire sexual health information from medical care may be misplaced. Universities have an excellent opportunity to provide young men with appropriate sexual health information and could offer novel strategies to help young men look after their sexual health.
