What do primary teachers need to understand, and how? Developing an applied linguistics curriculum for pre-service primary school teacher
Seminars were designed to encourage debate about the applied linguistics understandings that are most helpful to primary school teachers in designing and teaching the language and literacy curriculum, in working with pupils with identified speech and language needs, and in working with other professionals such as educational psychologists and speech and language therapists. Participants were invited to consider what would be most helpful for primary-school teachers to understand about applied linguistics perspectives, and how this understanding could best be developed. These seminars are possibly the first UK opportunity for such a wide range of people to discuss these issues. Discussion came not only from the different professional concerns and research perspectives but also from differences in how Scotland and England make, implement and monitor language and literacy education policy. The two seminars were designed to run as a conversation, and the papers in the second seminar developed themes and issues raised in the first, as well as introducing new themes of their own. The first seminar made the case for how applied linguistics perspectives can, and do, inform the curriculum and pedagogy in primary schools. Professor Debra Myhill (Exeter University) began by reporting on her research on Writers as Designers. She summarised some of the research on young writers' linguistic development - their lexical choices, syntactic features, and thematic variety - arguing that linguistic knowledge is necessary for good writers but not sufficient: good writers need also to have access to a thinking repertoire from which they design, craft and shape texts that meet their communicative goals. In doing this, the relationship between the writer, the text and context is central, and teachers need to draw on knowledge from all these perspectives
Dietary astaxanthin levels affect colour, growth, carotenoid digestibility and the accumulation of specific carotenoid esters in the Giant Tiger Shrimp, Penaeus monodon
The carotenoid astaxanthin (Axn) plays a vital role in shrimp pigmentation, with direct influence on product quality, and forms a significant cost component of shrimp aquaculture feeds. However, the effects of dietary Axn on other measures of shrimp physiological performance are varied, and the efficiency of carotenoid uptake from the diet and deposition in shrimp tissues is poorly defined. This study fed juvenile shrimp (Penaeus monodon) diets that contained 0, 25, 50 or 100 mg kg-1 Axn for 6 weeks. Shrimp fed carotenoid-free diets had significantly reduced colour and growth than those fed carotenoids, but survival was unaffected. Carotenoid digestibility improved as dietary carotenoid levels increased, and was 98.5% in shrimp fed 100 mg kg-1 Axn. After 6 weeks, whole body carotenoid levels were significantly depleted in 0 or 25 mg kg-1 fed shrimp, compared with those fed 50 or 100 mg kg-1 or compared with initial shrimp. This study also showed that Axn monoesters were enriched with saturated fatty acids, whereas Axn diesters were enriched with monounsaturated and polyunsaturated fatty acids. Combined, these studies demonstrate that a total dietary carotenoid intake of between 25 and 50 mg kg-1 Axn is required for normal shrimp growth and health in P. monodon. Evidence suggests that there is a functional role for the accumulation of carotenoids and the formation of specific Axn fatty acid esters, and these may be linked to the metabolism, storage, mobilization or deposition of Axn within various tissues

Investigating harms of testing for ovarian cancer â psychological outcomes and cancer conversion rates in women with symptoms of ovarian cancer:A cohort study embedded in the multicentre ROCkeTS prospective diagnostic study
Objective: To investigate psychological correlates in women referred with suspected ovarian cancer via the fastâtrack pathway, explore how anxiety and distress levels change at 12 months postâtesting, and report cancer conversion rates by age and referral pathway. Design: Singleâarm prospective cohort study. Setting: Multicentre. Secondary care including outpatient clinics and emergency admissions. Population: A cohort of 2596 newly presenting symptomatic women with a raised CA125 level, abnormal imaging or both. Methods: Women completed anxiety and distress questionnaires at recruitment and at 12 months for those who had not undergone surgery or a biopsy within 3 months of recruitment. Main outcome measures: Anxiety and distress levels measured using a sixâitem short form of the StateâTrait Anxiety Inventory (STAIâ6) and the Impact of Event Scale â Revised (IESâr) questionnaire. Ovarian cancer (OC) conversion rates by age, menopausal status and referral pathway. Results: Overall, 1355/2596 (52.1%) and 1781/2596 (68.6%) experienced moderateâtoâsevere distress and anxiety, respectively, at recruitment. Younger age and emergency presentations had higher distress levels. The clinical category for anxiety and distress remained unchanged/worsened in 76% of respondents at 12 months, despite a nonâcancer diagnosis. The OC rates by age were 1.6% (95% CI 0.5%â5.9%) for ag

Priority species to support the functional integrity of coral reefs
Ecosystem-based management on coral reefs has historically focussed on biodiversity conservation through the establishment of marine reserves, but it is increasingly recognised that a subset of species can be key to the maintenance of ecosystem processes and functioning. Specific provisions for these key taxa are essential to biodiversity conservation and resilience-based adaptive management. While a wealth of literature addresses ecosystem functioning on coral reefs, available information covers only a subset of specific taxa, ecological processes and environmental stressors. What is lacking is a comparative assessment across the diverse range of coral reef species to synthesise available knowledge to inform science and management. Here we employed expert elicitation coupled with a literature review to generate the first comprehensive assessment of 70 taxonomically diverse and functionally distinct coral reef species from microbes to top predators to summarise reef functioning. Although our synthesis is largely through the lens of the Great Barrier Reef, Australia, a particularly data-rich system, it is relevant to coral reefs in general. We use this assessment to evaluate which taxa drive processes that maintain a healthy reef and whether management of these taxa is considered a priority (i.e. are they vulnerable?) or is feasible (i.e. can they be managed?). Scientific certainty was scored to weight our recommendations, particularly when certainty was low. We use five case studies to highlight critical gaps in knowledge that limit our understanding of ecosystem functioning. To inform the development of novel management strategies and research objectives, we identify taxa that support positive interactions and enhance ecosystem performance, including those where these roles are currently underappreciated. We conclude that current initiatives effectively capture many priority taxa but that there is significant room to increase opportunities for underappreciated taxa in both science and management to maximally safeguard coral reef functioning

Typical investigational medicinal products follow relatively uniform regulations in 10 European Clinical Research Infrastructures Network (ECRIN) countries
<p>Abstract</p> <p>Background</p> <p>In order to facilitate multinational clinical research, regulatory requirements need to become international and harmonised. The EU introduced the Directive 2001/20/EC in 2004, regulating investigational medicinal products in Europe.</p> <p>Methods</p> <p>We conducted a survey in order to identify the national regulatory requirements for major categories of clinical research in ten European Clinical Research Infrastructures Network (ECRIN) countries-Austria, Denmark, France, Germany, Hungary, Ireland, Italy, Spain, Sweden, and United Kingdom-covering approximately 70% of the EU population. Here we describe the results for regulatory requirements for typical investigational medicinal products, in the ten countries.</p> <p>Results</p> <p>Our results show that the ten countries have fairly harmonised definitions of typical investigational medicinal products. Clinical trials assessing typical investigational medicinal products require authorisation from a national competent authority in each of the countries surveyed. The opinion of the competent authorities is communicated to the trial sponsor within the same timelines, i.e., no more than 60 days, in all ten countries. The authority to which the application has to be sent to in the different countries is not fully harmonised.</p> <p>Conclusion</p> <p>The Directive 2001/20/EC defined the term 'investigational medicinal product' and all regulatory requirements described therein are applicable to investigational medicinal products. Our survey showed, however, that those requirements had been adopted in ten European countries, not for investigational medicinal products overall, but rather a narrower category which we term 'typical' investigational medicinal products. The result is partial EU harmonisation of requirements and a relatively navigable landscape for the sponsor regarding typical investigational medicinal products.</p
Correlation between DNA damage responses of skin to a test dose of radiation and late adverse effects of earlier breast radiotherapy
Aim: To correlate residual double strand breaks (DSB) 24 h after 4 Gy test doses to skin in vivo and to lymphocytes
in vitro with adverse effects of earlier breast radiotherapy (RT).
Patients and methods: Patients given whole breast RT P5 years earlier were identified on the basis of
moderate/marked or minimal/no adverse effects despite the absence (âRT-Sensitiveâ, RT-S) or presence
(âRT-Resistantâ, RT-R) of variables predisposing to late adverse effects. Residual DSB were quantified in
skin 24 h after a 4 Gy test dose in 20 RT-S and 15 RT-R patients. Residual DSB were quantified in lymphocytes
irradiated with 4 Gy in vitro in 30/35 patients.
Results: Mean foci per dermal fibroblast were 3.29 (RT-S) vs 2.80 (RT-R) (p = 0.137); 3.28 (RT-S) vs 2.60
(RT-R) in endothelium (p = 0.158); 2.50 (RT-S) vs 2.41 (RT-R) in suprabasal keratinocytes (p = 0.633); 2.70
(RT-S) vs 2.35 (RT-R) in basal epidermis (p = 0.419); 12.1 (RT-S) vs 10.3 (RT-R) in lymphocytes
(p = 0.0052).
Conclusions: Residual DSB in skin following a 4 Gy dose were not significantly associated with risk of late
adverse effects of breast radiotherapy, although exploratory analyses suggested an association in severely
affected individuals. By contrast, a significant association was detected based on the in vitro response of
lymphocytes
