Abstract
A brain-computer interface (BCI) offers movement-free control of a computer application and is achieved by reading and translating the cortical activity of the brain into semantic control signals. Motion-onset visual evoked potentials (mVEP) are neural potentials employed in BCIs and occur when motion-related stimuli are attended visually. mVEP dynamics are correlated with the position and timing of the moving stimuli. To investigate the feasibility of utilizing the mVEP paradigm with video games of various graphical complexities including those of commercial quality, we conducted three studies over four separate sessions comparing the performance of classifying five mVEP responses with variations in graphical complexity and style, in-game distractions, and display parameters surrounding mVEP stimuli. To investigate the feasibility of utilizing contemporary presentation modalities in neurogaming, one of the studies compared mVEP classification performance when stimuli were presented using the oculus rift virtual reality headset. Results from 31 independent subjects were analyzed offline. The results show classification performances ranging up to 90% with variations in conditions in graphical complexity having limited effect on mVEP performance; thus, demonstrating the feasibility of using the mVEP paradigm within BCI-based neurogaming.

Abstract
More than 10,000 Caspian seals ( Phoca caspica) were reported dead in the Caspian Sea during spring and summer 2000. We performed necropsies and extensive laboratory analyses on 18 seals, as well as examination of the pattern of strandings and variation in weather in recent years, to identify the cause of mortality and potential contributory factors. The monthly stranding rate in 2000 was up to 2.8 times the historic mean. It was preceded by an unusually mild winter, as observed before in mass mortality events of pinnipeds. The primary diagnosis in 11 of 13 seals was canine distemper, characterized by broncho-interstitial pneumonia, lymphocytic necrosis and depletion in lymphoid organs, and the presence of typical intracytoplasmic inclusion bodies in multiple epithelia. Canine distemper virus infection was confirmed by phylogenetic analysis of reverse transcriptase-polymerase chain reaction products. Organochlorine and zinc concentrations in tissues of seals with canine distemper were comparable to those of Caspian seals in previous years. Concurrent bacterial infections that may have contributed to the mortality of the seals included Bordetella bronchiseptica (4/8 seals), Streptococcus phocae (3/8), Salmonella dublin (1/8), and S. choleraesuis (1/8). A newly identified bacterium, Corynebacterium caspium, was associated with balanoposthitis in one seal. Several infectious and parasitic organisms, including poxvirus, Atopobacter phocae, Eimeria- and Sarcocystis-like organisms, and Halarachne sp. were identified in Caspian seals for the first time.

Abstract
Objective: To assess a novel device designed for ‘inversion’ stripping of the long saphenous vein during varicose vein surgery. Design: A prospective, randomized trial. Setting: The Day Surgery Unit of a District General Hospital. Patients: Thirty consecutive patients undergoing unilateral, varicose vein surgery, all fulfilling appropriate requirements for day surgery. Outcome: Peroperative assessment of blood loss and postoperative assessment of complications, bruising, pain and length of stripper exit wound. Results: ‘Inversion’ stripping caused less peroperative blood loss ( p < 0.01). It reduced postoperative morbidity (for pain at 1 week, p = 0.02) and gave an improved cosmetic result (with a smaller stripper exit wound, p < 0.01). Conclusion: An easy-to-use, ‘inversion’ stripping device is described that can reduce the postoperative morbidity often associated with primary varicose vein surgery and can enhance cosmesis.

Abstract
High numbers of eosinophils are observed in parasitic infections and allergic diseases, where they are proposed to be terminally differentiated effector cells that play beneficial role in host defence, or cause harmful inflammatory response. Eosinophils have been associated with killing of schistosomulae in vitro, but there is growing evidence that eosinophils can play additional immuno‐regulatory role. Here, we report results of a study that examines peripheral blood mononuclear cell (PBMC) cytokine responses to Schistosoma mansoni adult worm antigen (SWA) when stimulated alone or enriched with autologous eosinophils. Production of the Th‐2 type cytokines interleukin (IL)‐4, IL‐5 and IL‐13 was lower (P = 0·017, 0·018 and <0·001, respectively) in PBMC + eosinophil cultures than in PBMC‐only cultures stimulated with SWA. Substantial levels of IL‐13, IL‐10, interferon gamma and tumour necrosis factor alpha were recorded in cultures of eosinophils, but none of these cytokines showed significant association with the observed eosinophil‐induced drop in cytokine responses of PBMC. Transwell experiments suggested that the observed effect is due to soluble mediators that downmodulate production of Th‐2 type cytokines. This study shows that eosinophils may down‐modulate schistosome‐specific Th‐2 type cytokine responses in S. mansoni‐infected individuals. The mechanism of this immune modulation remains to be elucidated.

Abstract
Abstract
HISTORIQUE: Le Comité consultatif national de l’immunisation (CCNI) recommande depuis 1993 la mise en place de programmes de vaccination universelle contre l’hépatite B au Canada. Depuis 1998, des programmes de vaccination universelle contre l’hépatite B sont place partout au pays. Les calendriers de vaccination systématique ne sont toutefois pas harmonisés.
OBJECTIFS: Mesurer la couverture vaccinale pour l’hépatite B rapportés et identifier les facteurs de risques associés à la non-vaccination.
MATÉRIALS/MÉTHODE: Nous avons analysé les données de 6805 adolescents de 17 ans inclus dans l’enquête nationale sur la couverture vaccinale des enfants (ENCVE) de 2013 pour identifier les facteurs socio-démographiques associés à la non-vaccination, c’est-à-dire n’avoir reçu aucune dose du vaccin contre l’hépatite B. Les variables indépendantes incluses dans l’analyse étaient les provinces et territoires, le fait que les adolescents ou les parents soient nés à l’extérieur du Canada ou non, le statut matrimonial des parents et le niveau d’éducation de ces derniers en plus du revenu familial moyen. Les rapports de cotes ont été calculés au moyen de regressions logistiques simples et multiples. Les intervalles de confiance ont été estimés par la méthode bootstrap.
RÉSULTATS: En tout, 87.9% des adolescents avaient reçu au moins une dose du vaccin. Il n’y avait pas d’association significative entre le statut socioéconomique et le statut vaccinal des enfants pour l’hépatite B. Il existe cependant des différences au niveau de couverture vaccinale pour ce vaccin entre les différentes provinces et territoires du Canada. De plus, à 17 ans le fait d’être né à l’extérieur du Canada était associé à un risque plus élevé d’être non-vacciné comparativement aux enfants nés au Canada, et ce à la limite du seuil de signification (p=0.556).
CONCLUSION: Il existe des différences entre les taux de couvertures des provinces et territoires malgré des programmes de vaccination systéma-tique contre l’hépatite B dans toutes les juridictions. Par contre, il ne semble pas y avoir d’inégalité socioéconomique en lien avec le statut vac-cinal de l’hépatite B des adolescents. Ceci est un fait encourageant pour les programmes de promotion en place dans le pays.

Abstract
BACKGROUND Many young children in the U.S. spend a significant portion of their day in child care facilities where they may be exposed to contaminants linked to adverse health effects. Exposure data on volatile organic compounds (VOCs) and particulate matter (PM) in these settings is scarce. OBJECTIVE To guide the design of a larger exposure assessment study in urban child care facilities, we conducted a pilot study in which we characterized indoor concentrations of select VOCs and PM. METHODS We recruited 14 child care facilities in the District of Columbia (Washington, DC) and measured indoor concentrations of seven VOCs (n=35 total samples; 2-5 samples per facility): benzene, carbon tetrachloride, chloroform, ethylbenzene, o-xylene, p-xylene, and toluene in all facilities; and collected real-time PM measurements in seven facilities. We calculated descriptive statistics for contaminant concentrations and computed intraclass correlation coefficients (ICC) to evaluate the variability of VOC levels indoors. We also administered a survey to collect general health information on the children attending these facilities, and information on general housekeeping practices and proximity of facilities to potential sources of target contaminants. RESULTS We detected six of the seven VOCs in the majority of child care facilities with detection frequencies ranging from 71% to 100%. Chloroform and toluene were detected in all samples. Median (range) concentrations for toluene, chloroform, benzene, o-xylene, ethylbenzene, and carbon tetrachloride were: 5.6µg/m(3) (0.6-16.5µg/m(3)), 2.8µg/m(3) (0.4-53.0µg/m(3)), 1.4µg/m(3) (below the limit of detection or <LOD - 4.4µg/m(3)), 1.1µg/m(3) (<LOD - 35.7µg/m(3)), 1.0µg/m(3) (<LOD - 28.5µg/m(3)), and 1.0µg/m(3) (<LOD - 1.6µg/m(3)), respectively. The ICCs for the VOCs measured ranged from 0.32 to 0.75. Child care facility median concentrations for PM2.5 and PM10 were 20.1µg/m(3) and 26.3µg/m(3), respectively. Chlorine bleach, a source of chloroform, was used in almost all facilities, air fresheners and/or scented candles were used in half of the facilities, and at least one child in each facility had physician-diagnosed asthma (median asthma prevalence rate=10.2%). CONCLUSION We found quantifiable levels of VOCs and PM in the child care facilities sampled. Given that exposures to environmental contaminants during critical developmental stages may have long lasting impacts on children's health, larger studies are needed to characterize and identify sources of exposures to these and other indoor contaminants to develop exposure mitigation strategies.

Abstract
Coal mining generates large quantities of complex effluent, and this often contains high levels of dissolved solids, suspended solids, metals, hydrocarbons, salts and other compounds. Substantial volumes of mine wastewater are periodically discharged into the environment, through both planned and accidental releases, and this raises concerns about the potential for adverse impacts on aquatic wildlife. There have been few attempts to explore sub-lethal effects of coal mine wastewater on amphibians compared to other organisms, and this is particularly true for Australian species. To address existing knowledge gaps, we exposed striped marsh frog (Limnodynastes peronii) tadpoles to 25, 50 and 100% coal mine wastewater collected from two holding dams (CMW1 and CMW2) located at an open cut mine in Central Queensland, Australia. The exposure lasted for four weeks, after which survival, growth and development, swimming behaviour, and concentrations of metals and metalloids in tail and liver tissues were assessed. Physico-chemical parameters varied considerably between sites, with higher turbidity, nutrients, total and dissolved organic carbon, alkalinity and arsenic (As) concentrations at CMW1, and higher conductivity, salinity, dissolved solids, hardness and sulfate levels at CMW2. There was no mortality in controls and less than 5% mortality in CMW1 treatments, whereas survival was significantly decreased in tadpoles exposed to CMW2 with 40 and 55% mortality in the 50 and 100% treatments, respectively. Development was significantly delayed in 100% CMW1 wastewater, but tadpole size (growth) was not influenced by the exposure. Hepatosomatic indices were significantly increased in tadpoles exposed to 25 and 50% CMW1 but not the 100% treatment group. Exposed tadpoles (predominantly those exposed to CMW1) exhibited increased activity after very short-term exposure (24h), but this did not persist as animals approached metamorphic climax. At the end of the experiment, tadpoles exposed to both wastewaters had elevated levels of selenium (Se), cobalt (Co) and As in tail and liver tissue compared to controls. Manganese (Mn) levels were also elevated in livers and tails of CMW2 exposed tadpoles. Hepatic tissue accumulated 8-9 times higher concentrations of Co, Mn and Se compared to tail tissue, irrespective of treatments. Future research is warranted to explore possible relationships between metal bioaccumulation, morpho-physiological effects during development, and subsequent higher-level outcomes related to individual performance and population fitness.

Abstract
The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico was the largest maritime oil spill in history resulting in the accumulation of genotoxic substances in the air, soil, and water. This has potential far-reaching health impacts on cleanup field workers and on the populations living in the contaminated coastal areas. We have employed portable airborne particulate matter samplers (SKC Biosampler Impinger) and a genetically engineered bacterial reporter system (umu-ChromoTest from EBPI) to determine levels of genotoxicity of air samples collected from highly contaminated areas of coastal Louisiana including Grand Isle, Port Fourchon, and Elmer's Island in the spring, summer and fall of 2011, 2012, 2013 and 2014. Air samples collected from a non-contaminated area, Sea Rim State Park, Texas, served as a control for background airborne genotoxic particles. In comparison to controls, air samples from the contaminated areas demonstrated highly significant increases in genotoxicity with the highest values registered during the month of July in 2011, 2013, and 2014, in all three locations. This seasonal trend was disrupted in 2012, when the highest genotoxicity values were detected in October, which correlated with hurricane Isaac landfall in late August of 2012, about five weeks before a routine collection of fall air samples. Our data demonstrate: (i) high levels of air genotoxicity in the monitored areas over last four years post DWH oil spill; (ii) airborne particulate genotoxicity peaks in summers and correlates with high temperatures and high humidity; and (iii) this seasonal trend was disrupted by the hurricane Isaac landfall, which further supports the concept of a continuous negative impact of the oil spill in this region.

Abstract
Coal mining generates large quantities of complex effluent and may pose a threat to aquatic wildlife. Despite this, few studies have explored the consequences of exposure to mine wastewater on aquatic organisms, and this is particularly true for the Australian environment. We investigated sub-lethal behavioural responses in a native Australian fish exposed to wastewater from two releasing dams (CMW1 and CMW2) located at an open cut coal mine in Central Queensland. Swimming activity and movement of empire gudgeons (Hypseleotris compressa) were assessed during a two-week exposure using video-tracking software. Increased activity was observed in exposed fish after 7 and 14 days. Specifically, we found a significant increase in the mean velocity and mobility of fish exposed to CMW1 treatments. Exposed fish also spent on average 23% more time in the peripheral zone compared to controls after 14-d exposures. A similar response pattern was observed in fish exposed to CMW2, but differences between treated and control fish did not generally reach statistical significance. Alterations to normal swimming activity and movement patterns can be indicative of a stress response in fish, and could subsequently lead to negative population-level impacts by increasing the conspicuousness of exposed individuals to predators, or by altering foraging abilities. More research is warranted to explore relationships between behavioural and physiological outcomes, including endocrine disruption, and subsequent population-level outcomes in aquatic organisms at risk of exposure to coal process-affected water.

Abstract
We present a system of nonlinear ordinary differential equations used to quantify the complex dynamics of the interactions between tumor growth, vasculature generation, and antiangiogenic treatment. The primary dataset consists of longitudinal tumor size measurements (1,371 total observations) in 105 colorectal tumor‐bearing mice. Mice received single or combination administration of sunitinib, an antiangiogenic agent, and/or irinotecan, a cytotoxic agent. Depending on the dataset, parameter estimation was performed either using a mixed‐effect approach or by nonlinear least squares. Through a log‐likelihood ratio test, we conclude that there is a potential synergistic interaction between sunitinib when administered in combination with irinotecan in preclinical settings. Model simulations were then compared to data from a follow‐up preclinical experiment. We conclude that the model has predictive value in identifying the therapeutic window in which the timing between the administrations of these two drugs is most effective.

Abstract
Delays in effective treatment of a first episode psychosis can result in more severe symptoms, a longer time to achieve symptom control and a poorer quality of life; yet around 40% do not take antipsychotic medication as prescribed. There is evidence that patients and staff have different perceptions of what affects adherence with medication. Research in adults suggests healthcare professionals and patients understand the importance of good insight in promoting adherence with medication for schizophrenia; however, healthcare staff may overestimate the impact of side effects and underestimate the importance of medication effectiveness. There is also some evidence to suggest that motivations to take prescribed medication may differ in first and multi-episode psychosis. This research therefore sought views of staff working with adolescents diagnosed with first episode psychosis about what factors affected adherence with antipsychotic medication. Staff responding to the survey felt that young people were more likely to take medication if they felt it would make them better, prevent relapse and if they had a positive rapport with staff. As in an adult population, side effects, particularly weight gain, sedation and muscular side effects, were expressed as a common reason for poor adherence. Doctors and nurses assigned differing importance to parameters such as family views of medication, fear of admission and a preference for cannabis over medication suggesting that views may differ between professional groups Views of young people will be obtained in the next phase of the research study to enable comparison with staff views and consideration of staff interventions to better promote medication adherence. Antipsychotic medication is an effective treatment for first episode psychosis; yet 40% of patients do not take medication as prescribed. Previous research in adults with schizophrenia comparing healthcare professional and patient views suggests that while healthcare professionals recognize the importance of insight in promoting medication adherence, they underestimate the importance of medication efficacy and overestimate the impact of side effects. It was hypothesized that staff in this study would also recognize the importance of insight and positive medication attitudes in teenagers with psychosis, but overestimate the impact of side effects on medication adherence. This cross-sectional observational study sought staff views about factors affecting antipsychotic medication adherence in those aged between 14 and 18 years. An online survey was distributed and 60 responses were subsequently returned. Staff felt that good medication insight as well as positive relationships with staff were important determinants of good medication adherence. The most important influences of poor adherence were poor insight, side effects of medication and a wish to exert personal control around medication decisions. The results therefore confirmed the initial hypothesis. Published literature also provides support for some, but not all, of the staff views expressed in survey responses.
