    • Visualisation of xanthan conformation by atomic force microscopy

      Moffat, Jonathan; Morris, Victor J.; Al-Assaf, Saphwan; Gunning, A. Patrick; Asylum Research an Oxford Instruments Company; Norwich Research Park; University of Chester (Elsevier, 2016-04-20)
      Direct visual evidence obtained by atomic force microscopy demonstrates that when xanthan is adsorbed from aqueous solution onto the heterogeneously charged substrate mica, its helical conformation is distorted. Following adsorption it requires annealing for several hours to restore its ordered helical state. Once the helix state reforms, the AFM images obtained showed clear resolution of the periodicity with a value of 4.7 nm consistent with the previously predicted models. In addition, the images also reveal evidence that the helix is formed by a double strand, a clarification of an ambiguity of the xanthan ultrastructure that has been outstanding for many years.
    • Visualizing multivariate analysis - An intuitive approach to high dimensional statistical extractions

      Lewis, Stephen J.; Chester College of Higher Education (Oxbow Books (for The Osteoarchaeological Research Group), 1997-12-01)
      The numerical output of multivariate statistical analyses may extend to a greater number of dimensions than can be comprehended and so may appear abstract and divorced from the original data. A need arises, therefore, for the provision of a more intuitive understanding of the results of such techniques - perhaps of a graphical nature. A simple method is to plot, what have come to be known as, Andrews' curves. A tabular procedure, using a standard computer spreadsheet, is described whereby the coefficients produced by various multivariate statistical techniques can be substituted into a simple equation to produce a smooth, wave-like curve characterising the source data. Importantly, this technique also provides a means whereby groups of curves may be compared visually to identify clusters and curves of similar or dissimilar overall shape. Similarly, "outliers" may also be spotted.
    • Vitamin D and cardiometabolic disease risk: A RCT and cross-sectional study

      Mushtaq, Sohail; Hughes, Stephen F.; Agbalalah, Tari (University of Chester, 2017-01-30)
      Given the strong evidence for a beneficial role of vitamin D in diabetes and CVD pathogenesis, and the prevalence of vitamin D deficiency, vitamin D supplementation has been advocated for the prevention of cardiometabolic disease. To provide information on the effects of 5,000IU (125µg) vitamin D3 on cardiometabolic risk, a double blind, RCT in a cohort of overweight and obese UK adult males with plasma 25(OH)D concentration < 75nmol/L for a duration of 8 weeks was conducted. To the best of my knowledge, this is the first RCT to investigate the effect of 5,000IU (125µg) vitamin D3 on cardiometabolic markers in vitamin D insufficient, non-hypertensive and non-diabetic overweight and obese adult males.
    • Vitamin D3 supplementation for 8 weeks leads to improved haematological status following the consumption of an iron-fortified breakfast cereal: a double-blind randomised controlled trial in iron-deficient women.

      Mushtaq, Sohail; Ahmed Fuzi, Salma F; University of Chester (Cambridge University Press, 2019-03-01)
      The effect of 38 µg (1500 IU) daily vitamin D3 supplementation, consumed with an iron-fortified breakfast cereal for 8 weeks, on haematological indicators in iron-deficient female subjects was investigated. Fifty iron-deficient subjects (plasma ferritin concentration < 20 µg/L; mean age ± SD: 27.4 ± 9.4 years) were randomised to consume an iron-fortified breakfast cereal containing 9 mg of iron daily, with either a vitamin D3 supplement or placebo. Blood samples were collected at baseline, interim (4 weeks) and post-intervention (8 weeks) for measurement of iron and vitamin D status biomarkers. The effect of intervention was analysed using mixed-model repeated measures ANOVA. Significant increases were observed in two main haematological indices: haemoglobin concentration and haematocrit level from baseline to post-intervention in the vitamin D group, but not in the placebo group. The increase from baseline to post-intervention in haemoglobin concentration in the vitamin D group (135 ± 11 to 138 ± 10 g/L) was significantly higher compared to the placebo group (131 ± 15 to 128 ± 13 g/L) (P=0.037). The increase in haematocrit level from baseline to post-intervention was also significantly higher in the vitamin D group (42.0 ± 3.0 to 43.8 ± 3.4%) compared to the placebo group (41.2 ± 4.3 to 40.7 ± 3.6%) (P=0.032). Despite the non-significant changes in plasma ferritin concentration, this study demonstrates that 38 µg supplemental vitamin D, consumed daily, with iron-fortified breakfast cereal led to improvement in haemoglobin concentration and haematocrit levels in women with low iron stores. These findings may have therapeutic implications in the recovery of iron status in iron-deficient populations at a healthcare level.

    • Weaned age variation in the Virunga mountain gorillas (Gorilla beringei beringei)

      Eckardt, Winnie; Fawcett, Katie; Fletcher, Alison W.; University of Chester; The Dian Fossey Gorilla Fund International (Springer, 2016-02-02)
      Weaning marks an important milestone during life history in mammals indicating nutritional independence from the mother. Age at weaning is a key measure of maternal investment and care, affecting female reproductive rates, offspring survival and ultimately the viability of a population. Factors explaining weaned age variation in the endangered mountain gorilla are not yet well understood. This study investigated the impact of group size, group type (one-male versus multi-male), offspring sex, as well as maternal age, rank, and parity on weaned age variation in the Virunga mountain gorilla population. The status of nutritional independence was established in 69 offspring using long-term suckling observations. A Cox-regression with mixed effects was applied to model weaned age and its relationship with covariates. Findings indicate that offspring in one-male groups are more likely to be weaned earlier than offspring in multi-male groups, which may reflect a female reproductive strategy to reduce higher risk of infanticide in one-male groups. Inferior milk production capacity and conflicting resource allocation between their own and offspring growth may explain later weaning in primiparous mothers compared to multiparous mothers. Sex-biased weaned age related to maternal condition defined by parity, rank, and maternal age will be discussed in the light of the Trivers-Willard hypothesis. Long-term demographic records revealed no disadvantage of early weaning for mother or offspring. Population growth and two peaks in weaned age within the Virunga population encourage future studies on the potential impact of bamboo shoots as a weaning food and other environmental factors on weaning.
    • Western diet increases cardiac ceramide content in healthy and hypertrophied hearts.

      Butler, Thomas; University of Chester, University of York, University of Hull (Elsevier, 2017-11-01)
      BACKGROUND AND AIMS: Obesity and cardiac left ventricular hypertrophy (LVH) are recognised independent risk factors in the development of heart failure (HF). However, the combination of these factors may exacerbate the onset of cardiovascular disease by mechanisms as yet unclear. LVH leads to significant cellular remodelling, including alterations in metabolism which may result in an inappropriate accumulation of lipids and eventual lipotoxicity and apoptosis. The aim of the study was to determine the impact of dietary manipulation on cardiac metabolism in the obese and hypertrophied heart. METHODS AND RESULTS: LVH was induced via aortic constriction (AC) in an experimental model of cardiac hypertrophy and animals subjected to 9 weeks of dietary manipulation with either a standard, high fat, or a sucrose containing Western-style diet (SD, HFD and WD, respectively). This latter diet resulted in accelerated weight gain in both LVH/AC and control animals. LVH was greater in AC animals fed a WD, and both control and AC animals from this diet showed a significant reduction in cardiac fatty acid oxidation and increased triacylglycerol content. Ceramide content was significantly increased in the WD groups, with no additional effect of LVH. Comparison with a model of HF induced by exposure to Doxorubicin and WD showed exacerbated remodelling of cardiac ceramide species leading to increased C16 and C18 content. CONCLUSIONS: These findings highlight the inappropriate accumulation and re-distribution of cardiac ceramide species in a diet-induced model of obesity and LVH, potentially increasing susceptibility to cell death. The combination of increased fat and sugar leads to greater pathological remodelling and may explain why this diet pattern is consistently linked with poor cardiovascular outcomes.
    • “[We’re on the right track, baby], we were born that way!” Exploring sports participation in Norway

      Green, Ken; Thurston, Miranda; Vaage, Odd; Roberts, Ken; University of Chester; Hedmark University College; Norsk Statistisk Sentralbyra (Taylor & Francis, 2013-02-25)
      Based on quantitative data from the Norwegian Statistisk Sentralbyrå (Statistics Norway) study of Mosjon, Friluftsliv og Kulturaktiviteter, this paper explores trends in Norwegians' participation in sports, with a focus on young people. Norway boasts particularly high levels of sports participation as well as sports club membership and young Norwegians are the quintessential sporting omnivores. Among other things, the Statistics Norway study reveals substantial increases in participation (among young people and females especially) during the period 1997–2007, a shift in the peak of participation to the late teenage years, a relatively high level of lifelong participants, a re-bound effect in the post-child rearing years and a growth in lifestyle sports. Young Norwegians grow up in a socio-economic context of relative equality between the sexes and high standards of living. An abundance of natural and artificial outdoor and indoor sporting facilities alongside a well-established voluntary sports club sector and an elementary school system that emphasizes physical exercise and recreation, as well as high levels of parental involvement, add to the favourable socio-economic conditions to create seemingly optimal circumstances for sports participation. All these reinforce the sporting and physical recreation cultures deeply embedded in Norwegian society and embodied by the very many middle-class parents in a country which, for the time being at least, remains relatively young in demographic terms. In terms of lessons to be learned for policy towards sports and physical education beyond Norway, there may be grounds for some optimism around parental involvement in children's sport as well as the potential appeal of lifestyle sports. That said, it is likely to be the greater socio-economic equalities in Scandinavian countries such as Norway that make them unrealistic benchmarks for sports participation elsewhere.
    • What happened to the legacy from London 2012? A sociological analysis of the processes involved in preparing for a grassroots sporting legacy from London 2012 outside of the host city

      Lovett, Emily L.; Bloyce, Daniel; Edge Hill University; University of Chester (Taylor and Francis, 2017-02-01)
      Preparations for London 2012 included promises for a sporting legacy across Britain. APS data suggest that, despite a slight spike in 2012, we have not experienced the rise in participation promised. The importance of preparations for legacy were well documented but little research has examined these processes. We examine planning for sporting legacy within a non-Olympic city in England, Birmingham. 37 semi-structured interviews were conducted with people delivering sport in Birmingham to provide a figurational analysis of relationships involved. The change in government during the economic recession saw budget cuts and a reduction in sport development personnel. Whilst various organisations struggled financially, others wanted to link to legacy. This increase in groups involved led to confusion and the unintended outcome of ‘initiativitis’. In trying to leverage legacy, a strategic approach to managing potential opportunities with clear communication of opportunities is vital. A belief in inherent inspiration cannot be relied upon. Key words: London 2012, sport legacy, figurational sociology, Birmingham, initiativitis, school sports partnerships, policy, inherent inspiration, demonstration effect
    • What is the effect of aerobic exercise intensity on cardiorespiratory fitness in those undergoing cardiac rehabilitation? A systematic review with meta-analysis

      Mitchell, Braden L.; Lock, Merilyn J.; Parfitt, Gaynor; Buckley, John P.; Davison, Kade; Eston, Roger; University of South Australia, University Centre Shrewsbury/University of Chester (BMJ, 2018-08-18)
      18 Objective: Assess the role of exercise intensity on changes in cardiorespiratory fitness (CRF) in 19 patients with cardiac conditions attending exercise-based cardiac rehabilitation. 20 Design: Systematic review with meta-analysis. 21 Data sources: MEDLINE, Embase, CINAHL, SPORTDiscus, PsycINFO and Web of Science. 22 Eligibility criteria for selection: Studies assessing change in CRF (reported as peak oxygen uptake; 23 V̇O2peak) in patients post-myocardial infarction and revascularisation, following exercise-based 24 cardiac rehabilitation. Studies establishing V̇O2peak via symptom-limited exercise test with ventilatory 25 gas analysis and reported intensity of exercise during rehabilitation were included. Studies with 26 mean ejection fraction <40% were excluded. 27 Results: 128 studies including 13,220 patients were included. Interventions were classified as 28 moderate, moderate-to-vigorous or vigorous intensity based on published recommendations. 29 Moderate and moderate-to-vigorous intensity interventions were associated with a moderate 30 increase in relative V̇O2peak (standardised mean difference ± 95% CI = 0.94 ± 0.30 and 0.93 ± 0.17, 31 respectively), and vigorous-intensity exercise with a large increase (1.10 ± 0.25). Moderate and 32 vigorous intensity interventions were associated with moderate improvements in absolute V̇O2peak 33 (0.63 ± 0.34 and 0.93 ± 0.20, respectively), whereas moderate-to-vigorous intensity interventions 34 elicited a large effect (1.27 ± 0.75). Large heterogeneity among studies was observed for all analyses. 35 Subgroup analyses yielded statistically significant, but inconsistent, improvements in CRF. 36 Conclusion: Engagement in exercise-based cardiac rehabilitation was associated with significant 37 improvements in both absolute and relative V̇O2peak. Although exercise of vigorous intensity 38 produced the greatest pooled effect for change in relative V̇O2peak, differences in pooled effects 39 between intensities could not be considered clinically meaningful.

    • When transport policy becomes health policy: A documentary analysis of active travel policy in England

      Bloyce, Daniel; White, Christopher; University of Chester (Elsevier, 2018-09-17)
      There has been a succession of policy documents related to active travel published by the British government since the implementation of a National Cycle Network (NCN) in 1995. However, as the latest National Travel Survey (NTS) reveals, the number of journeys made by bike in the UK has remained steadfastly around only 2% (Department for Transport [DfT], 2018a). By using documentary analysis of the available official policy documents and statements, the aim of this paper is to make sense of the policies that have been published concerning active travel (AT) in England. This is done from a figurational sociological perspective. Three key themes emerge from the analysis: (1) the rhetorical, advisory level of the vast majority of the policies; (2) the reliance on a wide network of local authorities to implement AT policy; and (3) the focus placed on individuals to change their behaviour. Furthermore, the analysis reveals that despite a large number of policy publications from a range of government departments claiming to promote AT, little has actually changed in this time period in terms of a national agenda. Despite the successive policies, it seems there is little appetite on behalf of recent governments to make widespread infrastructural changes, where instead the focus has largely been on persuading the individual to seek more active modes of travel, increasingly for their own, individual ‘health’ gains.
    • Where are the women in geology?

      Burek, Cynthia V.; University of Chester (Leicester Literary and Philosophical Society, 2008)
      This article looks at the place of women in geology primarily from a historic viewpoint but also covering academia and geography. The role that women have played in the development of the science of geology has varied tremendously throughout history but is intimately linked the the context of women's place in society. Two issues will be looked at in detail - the effect of travel to field locations and the place of female role models (or the lack of them). In the realm of academic, the article will examine whether female geologists have favoured palaeontology and consider what other European countries think about female scientists and female geologists.
    • White-faced Darter distribution is associated with coniferous forests in Great Britain

      Geary, Matthew; von Hardenberg, Achaz; Conservation Biology Research Group, Department of Biological Science, University of Chester, Chester, CH1 4BJ
      Abstract 1) Understanding of dragonfly distributions is often geographically comprehensive but less so in ecological terms. 2) White-faced darter (Leucorhinnia dubia) is a lowland peatbog specialist dragonfly which has experienced population declines in Great Britain. White-faced darter are thought to rely on peat-rich pool complexes within woodland but this has not yet been empirically tested. 3) We used dragonfly recording data collected by volunteers of the British Dragonfly Society from 2005 to 2018 to model habitat preference for white-faced darter using species distribution models across Great Britain and, with a more detailed landcover dataset, specifically in the North of Scotland. 4) Across the whole of Great Britain our models used the proportion of coniferous forest within 1km as the most important predictor of habitat suitability but were not able to predict all current populations in England. 5) In the North of Scotland our models were more successful and suggest that habitats characterised by native coniferous forest and areas high potential evapotranspiration represent the most suitable habitat for white-faced darter. 6) We recommend that future white-faced darter monitoring should be expanded to include areas currently poorly surveyed but with high suitability in the North of Scotland. 7) Our results also suggest that white-faced darter management should concentrate on maintaining Sphagnum rich pool complexes and the maintenance and restoration of native forests in which these pool complexes occur.

    • Why is cardiac rehabilitation so important? Taking the traditional components of cardiac rehabilitation and making them fit contemporary service and patient needs

      Buckley, John P.; University of Chester (2011)
      Current statistics, available from outcomes following the National Service Framework (NSF) on Coronary Heart Disease,1 show that more people are surviving longer both after an acute coronary event and after a symptom-led diagnosis of coronary artery disease. In the past, cardiac rehabilitation (CR) played a key role in preventing premature mortality2 but more recently the greatly enhanced emergency services, better public education and more aggressive and widely available medical interventions may have diminished the effect of CR on premature mortality. There is now an increasing focus on productivity of life in those surviving acute myocardial events. Productivity refers to people’s active involvement in the local social and economic fabric of their families, friends and community. Some of these matters are less likely to be a function of technical medical care but rather a function of healthcare professionals providing therapeutic and health-promoting support for people to manage the physical, mental, domestic, occupational and social aspects of their lives – all of the goals at the heart of a good CR and chronic disease management and prevention programme.
    • Why pain is still a welfare issue for farm animals, and how facial expression may be the answer

      McLennan, Krista M.; University of Chester (MDPI, 2018-08-11)
      Pain is a sensory and emotional experience that significantly affects animal welfare and has negative impacts on the economics of farming. Pain is often associated with common production diseases such as lameness and mastitis, as well as introduced to the animal through routine husbandry practices such as castration and tail docking. Farm animals are prey species which tend not to overtly express pain or weakness, making recognizing and evaluating pain incredibly difficult. Current methods of pain assessment do not provide information on what the animal is experiencing at that moment in time, only that its experience is having a long term negative impact on its behavior and biological functioning. Measures that provide reliable information about the animals’ affective state in that moment are urgently required; facial expression as a pain assessment tool has this ability. Automation of the detection and analysis of facial expression is currently in development, providing further incentive to use these methods in animal welfare assessment.
