Spatial and genetic structure of directly‐transmitted parasites reflects the distribution of their specific amphibian hosts

Published: January 2018

AbstractParasite distributions depend on the local environment in which host infection occurs, and the surrounding landscape over which hosts move and transport their parasites. Although host and landscape effects on parasite prevalence and spatial distribution are difficult to observe directly, estimation of such relationships is necessary for understanding the spread of infections and parasite–habitat associations. Although parasite distributions are necessarily nested within host distributions, direct environmental influences on local infection or parasite effects on host dispersal could lead to distinct landscape or habitat relationships relative to their hosts. Our aim was to determine parasite spatial structure across a contiguous prairie by statistical modeling of parasite–landscape relationships combined with analysis of population genetic structure. We sampled northern leopard frogs (Lithobates pipiens) and wood frogs (L. sylvaticus) for host‐specific lung nematodes (Rhabdias ranae and R. bakeri; respectively) across the Sheyenne National Grassland in southeastern North Dakota and developed primers for 13 microsatellite loci for Rhabdias. The two Rhabdias species exhibited different correlations with landscape characteristics that conformed with that of their hosts, indicating transmission is driven by host ecology, probably density, and not directly by the environment. There was evidence for localized, patchy spatial genetic structure, but no broader‐scale geographic patterns, indicating no barriers to host and parasite dispersal. Nematodes cohabitating in an individual frog were most genetically similar. Worms within the same wetland were also genetically similar, indicating localized transmission and resulting wetland‐scale patchiness are not completely obscured by broad‐scale host–parasite dispersal. Beyond individual wetlands, we found no evidence of genetic isolation‐by‐distance or patchiness at the landscape‐scale.

Abstract
Helveticin-M, a novel Class III bacteriocin produced by Lactobacillus crispatus exhibited an antimicrobial activity against Staphylococcus aureus, S. saprophyticus, and Enterobacter cloacae. To understand how Helveticin-M injured target cells, Helveticin-M was cloned and heterologously expressed in Escherichia coli. Subsequently, the cell wall organization and cell membrane integrity of target cells were determined. The mechanism of cellular damage differed according to bacterial species. Based on morphology analysis, Helveticin-M disrupted the cell wall of Gram-positive bacteria and disorganized the outer membrane of Gram-negative bacteria, therefore, altering surface structure. Helveticin-M also disrupted the inner membrane, as confirmed by leakage of intracellular ATP from cells and depolarization of membrane potential of target bacteria. Based on cell population analysis, Helveticin-M treatment caused the increase of cell membrane permeability, but the cytosolic enzymes were not influenced, indicating that it was the sublethal injury. Therefore, the mode of Helveticin-M action is bacteriostatic rather than bactericidal.
Constructing the Identity of the Thai Judge: Virtue, Status, and Power
Authors: SOMANAWAT Kitpatchara 
Published: January 2018

AbstractA central aspect of Thai legal consciousness since the mid-twentieth century, widely shared among the general population, has been a perception that judges have an exalted status entitling them to make broad-ranging pronouncements about social and political issues as well as legal matters. Popular legal consciousness of the Thai judge has to a large extent been shared by the judges themselves, as well as by their families and followers. The power and authority of Thai judges go far beyond the limited formal role they are given in Thailand’s civil-law system. This article suggests that the exceptional status of the Thai judge derives from a process of identity construction, emphasizing four traits that set the ideal judge apart from ordinary people. The first is that a Thai judge must be a “khon di” (good person), with specific reference to the traditions of Thai Buddhism. The second is that a Thai judge must be polite, kind, and socially refined—a “phudi” (proper gentleman). The third characteristic of the ideal Thai judge is that he or she must be highly educated and knowledgeable about the law—a “phuru” (learned and wise person). The fourth trait is that a Thai judge must be a “phupakdi” (loyal servant of the king), not only loyal to the monarchy as an institution, but to the late King Rama IX as a person. When the identity of the Thai judge is constructed from these four constituent elements, the pronouncements of the judge acquire legitimacy, even when they range beyond the narrow letter of the law. The article explores this central aspect of Thai legal consciousness by analyzing the construction of judges’ identities through a distinctive set of historical documents—the cremation volumes (nangsue ngan sop) that are published and distributed at the funerals of noted public figures. These volumes contain a wealth of biographical information as well as related legal and historical material that shed light on the life and work of Thailand’s most prominent judges during the past 50 years.
Open-design: A state of the art review
Authors: Boisseau Étienne , Omhover Jean-François , Bouchard Carole 
Published: January 2018

The ‘open approach’ is rooted in the open-source and free-software movements. Its application has spread to more fields than computer engineering. Product design is impacted as well: we observe new stakeholders and practices challenging current structured design processes and leading to industrial successes. Open-design appears to be promising yet disruptive. Moreover, its distinctive features remain unclear.This paper aims to popularize this new concept, as well as to give both researchers and practitioners an overview of current research on open-design, and its consequences on design. For this, we conducted a systematic quantitative bibliometric analysis of 624 entries corresponding to the keyword ‘open-design’ in theScopusdatabase. This supports a qualitative synthesis of scientific literature, enabling us to summarize practices falling under the umbrella term ‘open-design’. As such, this paper traces the evolution of product design and the open approach. It also analyzes the impact of open-design on the design process as presented in the scientific literature. Finally, this paper develops a typology of open-design of tangible artifacts that distinguishes among three currently reported varieties of practice:do-it-yourself,meta-design, andindustrial ecosystems. As the major contribution of this paper, this typology is developed as a final discussion.
Exploring links between common mental health problems, alcohol/substance use and perpetration of intimate partner violence: A rapid ethnographic assessment with men in urban Kenya
Authors: Schafer A. , Koyiet P. 
Published: January 2018

Introduction:Kenya has some of the highest rates of gender-based violence (GBV) in the world, particularly intimate partner violence. World Vision completed a rapid ethnographic assessment to explore common problems faced by men and local perspectives about the links between men, mental health, alcohol use and GBV.Methods:Data from community free-listing surveys (n = 52), four focus group discussions and two key informant interviews formed the basis for thematic analysis and findings.Results:Lack of jobs, ‘idleness’ and finances were viewed as top priority concerns facing men; however, alcohol and substance use were equally prioritised. Family problems, crime and general psychosocial issues (e.g., high stress, low self-esteem) were also reported. Men withdrawing socially, changing behaviour and increasing alcohol consumption were described as signs that men were experiencing mental health challenges. The community observed alcohol use as the biggest cause of GBV, believing men resorted to drinking because of having ‘too much time’, marital conflict, psychosocial issues and access to alcohol. The findings theorise that a circular link between unemployment, alcohol and crime is likely contributing to familial, psychosocial and gender concerns, and that men's mental health support may assist to re-direct a trajectory for individuals at risk of perpetrating GBV.Conclusions:Data confirmed that GBV is a major concern in these Kenya communities and has direct links with alcohol use, which is subsequently linked to mental health and psychosocial problems. Attempting to disrupt progression to the perpetration of violence by men, via mental health care interventions, warrants further research.

AbstractThere are many parameters in agriculture that change over time in a sigmoid pattern. In the current study, the double logistic function was used to describe and simulate dry matter (DM) variation of winter rapeseed plant and to explain the growth rate under water stress. Irrigation treatments were full irrigation at all growth stages, water stress during the vegetative stage in early spring, water stress at flowering and podding stages, water stress at grain filling stage and rain-fed treatment with supplemental irrigation at time of planting. A high value for the goodness of fit (0.996) and low value for normalized root mean square error (0.085) showed that the double logistic function can describe and simulate DM variation of rapeseed accurately. DM predicted by the double logistic equation based on growing degree day was slightly closer to the measured DM compared with the DM predicted by the double logistic equation based on days after planting. Results showed that growth rate before the winter cold period was lower than that after this period. There were two maximum growth rates for winter rapeseed: the first occurred before cold period and another after.

AbstractObjective:To evaluate the incidence of acute rhinosinusitis in children with grass pollen induced rhinitis during the period of grass pollinosis.Methods:Children with nasal symptoms from grass pollen induced rhinitis but without rhinosinusitis symptoms were selected. Their parents were asked to complete a diary during pollen exposure to report nasal symptoms and drugs used daily. When rhinosinusitis was suspected, the confirmatory diagnosis of acute rhinosinusitis was made by fibro-endoscopy. Children without inhalant allergy served as controls.Results:Seventeen out of 242 children (7.0 per cent) had a diagnosis of acute rhinosinusitis, confirmed by fibro-endoscopy, during grass pollination, compared to 3 out of 65 (4.6 per cent) in the control group (p = 0.49). Among allergic children, those with acute rhinosinusitis had symptoms for a greater number of days and/or a higher symptoms score than children without acute rhinosinusitis.Conclusion:Children with grass pollen induced rhinitis during exposure to pollen have an incidence of endoscopically confirmed acute rhinosinusitis comparable to non-allergic children. This suggests that grass pollen induced rhinitis is a negligible risk factor for acute rhinosinusitis.
Nonlinear energy transfer and current sheet development in localized Alfvén wavepacket collisions in the strong turbulence limit
Authors: Verniero J. L. , Howes G. G. , Klein K. G. 
Published: January 2018

In space and astrophysical plasmas, turbulence is responsible for transferring energy from large scales driven by violent events or instabilities, to smaller scales where turbulent energy is ultimately converted into plasma heat by dissipative mechanisms. The nonlinear interaction between counterpropagating Alfvén waves, denoted Alfvén wave collisions, drives this turbulent energy cascade, as recognized by early work with incompressible magnetohydrodynamic (MHD) equations. Recent work employing analytical calculations and nonlinear gyrokinetic simulations of Alfvén wave collisions in an idealized periodic initial state have demonstrated the key properties that strong Alfvén wave collisions mediate effectively the transfer of energy to smaller perpendicular scales and self-consistently generate current sheets. For the more realistic case of the collision between two initially separated Alfvén wavepackets, we use a nonlinear gyrokinetic simulation to show here that these key properties persist: strong Alfvén wavepacket collisions indeed facilitate the perpendicular cascade of energy and give rise to current sheets. Furthermore, the evolution shows that nonlinear interactions occur only while the wavepackets overlap, followed by a clean separation of the wavepackets with straight uniform magnetic fields and the cessation of nonlinear evolution in between collisions, even in the gyrokinetic simulation presented here which resolves dispersive and kinetic effects beyond the reach of the MHD theory.

AbstractBiological surveys starting in the 1950s provided clear evidence that the Itombwe Massif, located in eastern Democratic Republic of Congo, is one of the most important areas for conservation in Africa. Further surveys in the mid 1990s and early 2000s showed key species were still present and could be conserved. Following a report on these surveys the Ministry of Environment established the Itombwe Reserve in 2006 without consulting local communities who have legitimate customary rights to reside within the area and use the region's natural resources. Although creating the Reserve was within the government's legal authority, its establishment violated the rights of the people there. Here we report over a decade of work by a consortium of international and national human rights and conservation NGOs, the local communities and the protected areas authority (Institut Congolais pour la Conservation de la Nature), to remediate this taking of customary rights. Starting in 2008 these partners began a participatory process with all 550 villages within and around the boundary of the Reserve. Using a community resource use mapping approach, developed from best practices, the team helped communities determine the boundary of the Reserve, and then pilot participatory zoning to identify zones for settlements, agriculture, hunting, gathering of non-timber forest products, and conservation. This process secured the customary rights of long-term residents in the Reserve and protected their lands from being taken by non-rights holders. As a result of this work the use rights of communities were largely restored and the communities agreed on 23 June 2016 to formalize the boundaries of the renamed Itombwe Nature Reserve.
Mechanisms underlying the occurrence of species in complex modified tropical landscapes: a case study of amphibians in the Osa Peninsula, Costa Rica
Authors: Matlaga Tanya J. Hawley 
Published: January 2018

Abstract:The mechanisms underlying occupancy patterns of species in modified tropical landscapes are poorly understood. The presence of adults in a modified habitat may not necessarily indicate the quality of the habitat for sub-adult stages. These issues were addressed by examining patterns in breeding-site use by adult frogs and tadpole performance across a pasture-forest gradient in the Osa Peninsula, Costa Rica. The use of artificial pools by adult frogs for breeding activity was quantified along three transects, with a pool located at the edge (0 m) and 10, 30 and 50 m into forest and pasture. Next, survival, size at metamorphosis and time to metamorphosis were quantified for tadpoles of Engyptomops pustulosus and Dendrobates auratus in artificial pools at the edge, pasture and forest. Adult frogs used breeding pools non-randomly; two species used pools only in pasture, whereas three species used pools only in forest. In addition, Smilisca phaeota used pools in pasture and at the edge while E. pustulosus used pools across the pasture-forest gradient. The habitat where adults used breeding pools generally also yielded high performance of their tadpoles, with some exceptions. Tadpole survival to metamorphosis was low in pastures (<5%) and higher in edge and forest (>18%) for D. auratus; in contrast, survival of E. pustulosus was over 80% in each habitat. Metamorphs of D. auratus were largest in edges but larval period did not differ among habitats. Metamorphs of E. pustulosus were 18% larger and larval period was 27% shorter in pastures compared with forest. These results suggest that modified habitats represent an ecological jackpot for some species, such that offspring performance is enhanced compared with that in forest habitat. Populations of other species may be restricted to forest habitat because of intolerable abiotic conditions in modified habitats. The results of this study indicate that adult breeding site use and tadpole performance contribute to mechanisms that underlie patterns of species occupancy in modified tropical landscapes.

AbstractBackgroundOptimal imaging is essential for catheter-based interventions in CHD. The three-dimensional models in volume-rendering technique currently in use are not standardised. This paper investigates the feasibility and impact of novel three-dimensional guidance with segmented and tessellated three-dimensional heart models in catheterisation of CHD. In addition, a nearly radiation-free two- to three-dimensional registration and a biplane overlay were used.Methods and resultsWe analysed 60 consecutive cases in which segmented tessellated three-dimensional heart models were merged with live fluoroscopy images and aligned using the tracheal bifurcation as a fiducial mark. The models were generated from previous MRI or CT by dedicated medical software. We chose the stereo-lithography format, as this promises advantage over volume-rendering-technique models regarding visualisation. Prospects, potential benefits, and accuracy of the two- to three-dimensional registration were rated separately by two paediatric interventionalists on a five-point Likert scale. Fluoroscopy time, radiation dose, and contrast dye consumption were evaluated. Over a 10-month study period, two- to three-dimensional image fusion was applied to 60 out of 354 cases. Of the 60 catheterisations, 73.3% were performed in the context of interventions. The accuracy of two- to three-dimensional registration was sufficient in all cases. Three-dimensional guidance was rated superior to conventional biplane imaging in all 60 cases. We registered significantly smaller amounts of used contrast dye (p<0.01), lower levels of radiation dose (p<0.02), and less fluoroscopy time (p<0.01) during interventions concerning the aortic arch compared with a control group.ConclusionsTwo- to three-dimensional image fusion can be applied successfully in most catheter-based interventions of CHD. Meshes in stereo-lithography format are accurate and base for standardised and reproducible three-dimensional models.

Published: January 2018

AbstractObjectiveTo assess the impact of the acute-phase response (APR) during inflammation on Fe, Zn and vitamin A biomarkers to allow accurate evaluation of micronutrient status in populations.DesignFerritin (FER), soluble transferrin receptor (TfR), retinol-binding protein (RBP), Zn, α1-acid glycoprotein and C-reactive protein concentrations were measured. Correction factors (CF) for each biomarker were calculated as the ratio for groups at different stages of inflammationv. the reference group without inflammation.Setting/SubjectsSenegalese (n594) and Cambodian schoolchildren (n2471); Cambodian women of reproductive age (n2117).ResultsTfR was higher during the incubation phase (CF=1·17) and lower during early and late convalescence (CF=0·87 and 0·78). FER was higher during all phases (CF=0·83, 0·48 and 0·65, respectively). RBP was higher during incubation (CF=0·88) and lower during early convalescence (CF=1·21). No effect of inflammation on Zn status was found.ConclusionsInflammation led to overestimation of Fe status and underestimation of vitamin A status. The response of the biomarker for vitamin A status to inflammation depended on the vitamin A status of the populations. Surprisingly, the assessment of Zn status was hardly affected by inflammation. Different phases of the APR had opposite effects on the assessment of Fe status using TfR. More research is needed to define the correct methods to adjust for inflammation in nutritional studies.
