Abstract
Purpose: Following increased interest in physical literacy (PL), development of appropriate tools for assessment has become an important next step for its operationalization. To forward the development of such tools, the objective of this study was to build the foundations of the Évaluation de la Littératie Physique (ELIP), designed to help reduce existing tensions in approaches to PL assessment that may be resulting in a low uptake into applied settings. Methods: We followed two steps: (1) the development of the first version of ELIP by deploying a Delphi method (n = 30); and (2) the modification of items through cognitive interviews with emerging adults (n = 32). Results: The expert consensus highlighted four dimensions of PL to be assessed-physical; affective; cognitive; and social-with new perspectives, including a preference for broad motor tests over fitness. Conclusion: Results offer new insights into the assessment of emerging adults' PL, but ELIP still requires further work concerning validity, reliability, and sensitivity.

Abstract
BACKGROUND Addressing behavioral health impacts of major disasters is a priority of increasing national attention, but there are limited examples of implementation strategies to guide new disaster responses. We provide a case study of an effort being applied in response to the 2016 Great Flood in Baton Rouge. METHODS Resilient Baton Rouge was designed to support recovery after major flooding by building local capacity to implement an expanded model of depression collaborative care for adults, coupled with identifying and responding to local priorities and assets for recovery. For a descriptive, initial evaluation, we coupled analysis of documents and process notes with descriptive surveys of participants in initial training and orientation, including preliminary comparisons among licensed and non-licensed participants to identify training priorities. RESULTS We expanded local behavioral health service delivery capacity through subgrants to four agencies, provision of training tailored to licensed and non-licensed providers and development of advisory councils and partnerships with grassroots and government agencies. We also undertook initial efforts to enhance national collaboration around post-disaster resilience. CONCLUSION Our partnered processes and lessons learned may be applicable to other communities that aim to promote resilience, as well as planning for and responding to post-disaster behavioral health needs.

Abstract
SummarySeptic arthritis of the elbow due to trauma was diagnosed in a young lioness and the joint was fused with internal and external fixations. External skeletal fixation was used for three months in order to augment bone plating and enhance bone fusion of the joint. Combining internal and external stabilizing procedures was tolerated by the animal and permitted limb salvage in a large, growing, non-domesticated animal.Septic and degenerative elbow arthritis due to trauma requires aggressive medical and surgical treatments to preserve limb function. In this case, systemic antibiotics, joint lavage and arthrodesis were used successfully in a lioness (Panthera leo) to save the forelimb.

Abstract
OBJECTIVE To examine the participant experiences regarding perceived barriers and facilitators which impact on consuming the Mediterranean diet in the East of England. DESIGN Qualitative methodology with focus groups. SETTING A healthy, middle-aged population situated in the East of England. INTERVENTION An 8-week Mediterranean dietary intervention trial. PARTICIPANTS Eleven participants (including three co-habiting partners) in three focus groups, ranging between 50-65 yrs with a mean age of 54.3 yrs (±4.0) RESULTS: Thematic analysis from the focus groups revealed that participants considered that the MD intervention had introduced a better quality of food, widening the food-horizon and allowed them to re-define cultural eating habits. They also reported several physical benefits from adapting to this diet and found the experience as positive. Whilst claiming that the MD was an enjoyable and pleasurable, the participants did express difficulty adapting to the eating pattern, finding difficulty in purchasing food items, an increase in food costs and found work, stress and time pressures undermining adherence. CONCLUSION The participants' experiences suggested that the MD was an encouraging dietary change with a middle aged non-Mediterranean based population group. Future MD interventions should tailor interventions and support participants closely, particularly with the necessary planning, organisation and purchasing involved with implementing this diet in non-Mediterranean countries. Secondly, researchers should also challenge any erroneous assumptions regarding the consumption of Mediterranean food, which may hinder implementation.

Abstract
The enzyme 2,4'-dihydroxyacetophenone dioxygenase (DAD) catalyses the conversion of 2,4'-dihydroxyacetophenone to 4-hydroxybenzoic acid and formic acid with the incorporation of molecular oxygen. Whilst the vast majority of dioxygenases cleave within the aromatic ring of the substrate, DAD is very unusual in that it is involved in C-C bond cleavage in a substituent of the aromatic ring. There is evidence that the enzyme is a homotetramer of 20.3 kDa subunits, each containing nonhaem iron, and its sequence suggests that it belongs to the cupin family of dioxygenases. In this paper, the first X-ray structure of a DAD enzyme from the Gram-negative bacterium Alcaligenes sp. 4HAP is reported, at a resolution of 2.2 Å. The structure establishes that the enzyme adopts a cupin fold, forming dimers with a pronounced hydrophobic interface between the monomers. The catalytic iron is coordinated by three histidine residues (76, 78 and 114) within a buried active-site cavity. The iron also appears to be tightly coordinated by an additional ligand which was putatively assigned as a carbonate dianion since this fits the electron density optimally, although it might also be the product formate. The modelled carbonate is located in a position which is highly likely to be occupied by the α-hydroxyketone group of the bound substrate during catalysis. Modelling of a substrate molecule in this position indicates that it will interact with many conserved amino acids in the predominantly hydrophobic active-site pocket where it undergoes peroxide radical-mediated heterolysis.

Abstract
BACKGROUND Food for Fitness is an on-going multi-component health promotion programme, delivered in primary and secondary schools by community nutrition assistants. The programme uses nutritional interventions aimed at promoting healthier eating practices for children. This service evaluation investigated the receipt and delivery of the programme, as perceived by local stakeholders who had experienced and administered the service. METHODS Semi-structured interviews and focus groups were carried out with three key stakeholder groups: health professionals (n = 9), school teachers (n = 10) and senior health officials (n = 3). Qualitative data were transcribed verbatim and received thematic analysis with deductive and inductive processes. RESULTS Stakeholders reported that the programme contributed to the development of food education and healthy-eating practices of children in the local area. Stakeholders considered that the main concern was the limited capacity and size of the service. They described problems with long-term sustainability in supporting schools with maintaining nutritional interventions, highlighting issues regarding contact, planning and organisation of several interventions. CONCLUSIONS The findings of the service evaluation inform service management, organisation and ground-level delivery. The use of stakeholder opinion provided contextualised information on the factors that impact on the implementation of the programme. The richness of the qualitative results can guide future planning and provision for similar health promotion nutrition programmes delivered in the school environment.

Abstract
The Structural Proteomics In Europe (SPINE) consortium contained a workpackage to address the automated X-ray analysis of macromolecules. The aim of this workpackage was to increase the throughput of three-dimensional structures while maintaining the high quality of conventional analyses. SPINE was able to bring together developers of software with users from the partner laboratories. Here, the results of a workshop organized by the consortium to evaluate software developed in the member laboratories against a set of bacterial targets are described. The major emphasis was on molecular-replacement suites, where automation was most advanced. Data processing and analysis, use of experimental phases and model construction were also addressed, albeit at a lower level.

Abstract
This study evaluated the effects of pre-exercise frusemide administration and hypertonic saline (H) infusion during anaesthesia on arterial pH, blood gases and electrolytes in 6 Thoroughbred horses anaesthetised immediately post exercise. Horses received either frusemide (F) (0.5 mg/kg, i.v.) or a saline placebo (P) injection 4 h prior to treadmill exercise. Exercise consisted of a 3 min warm-up at 40% VO2max followed by exercise to fatigue. Detomidine (40 micrograms/kg, i.v.) was given within 5 min of stopping and followed 5 min later by zolazepam-tiletamine (1.25 mg/kg, i.v.) to induce anaesthesia. During maintenance of anaesthesia using isoflurane in O2, either isotonic saline solution (I) or 7.5% H (4 ml/kg, i.v.) was administered. Arterial blood was sampled at the following times: prior to (Pre-F/P) and 4 h after (Pre-ex) F or P administration, 1 min after fatigue (Fatigue), 5 min after induction of anaesthesia (Post-ind), and just prior to and 15, 30 and 60 min after beginning isoflurane (ISFL) anaesthesia. Arterial pH and blood gas tensions, pulmonary arterial blood temperature, plasma [lactate], total protein and plasma [Na+], [K+], and [Cl-] were measured. Data were analyzed using 2-way ANOVA for repeated measures (P < 0.05). There were significant differences over time for all variables except total protein. Plasma [Na+] increased at Fatigue compared to Pre-F/P or Pre-ex in all treatment groups. Plasma [Na+] and [Cl-] increased during ISFL anaesthesia compared to Pre-F/P and Pre-ex in horses given H. During ISFL anaesthesia, plasma [Cl-] decreased compared to Pre-F/P in Group F+I horses. We conclude that acid-base, blood gas, and electrolyte changes associated with F are unlikely to influence management of horses anaesthetised immediately following supramaximal exercise to fatigue. Hypertonic saline infusion may help restore plasma [Cl-] faster in hypochloraemic horses requiring anaesthesia immediately after strenuous exercise.

Abstract
Recent concerns regarding the effects of the cosmic radiation field at aircraft altitudes on aircrew have resulted in a renewed interest in detailed measurements of the neutral and charged particle components in the atmosphere. CR-39 nuclear track detectors have been employed on a number of subsonic and supersonic aircraft to measure charge spectra and LET spectra at aircraft altitudes. These detectors are ideal for long term exposures required for these studies and their passive nature makes them suitable for an environment where interference with flight instrumentation could be a problem. We report here on measurements and analysis of short range tracks which were produced by high LET particles generated mainly by neutron interactions at aviation altitudes. In order to test the overall validity of the technique measurements were also carried out at the CERN-CEC field which simulates the radiation field at aviation altitudes and good agreement was found with dose values obtained using mainly heavy ion calibration.

Abstract
Polymorphism of the human c-Ha-ras-1 gene has been analysed in DNA from 168 individuals using the enzymes MspI and HpaII. In all, 35 bladder cancer patients, 28 melanoma patients, 22 Wilms' tumour patients, 24 first-degree relatives of Wilms' tumour or melanoma patients and 59 unaffected controls were studied. A total of 13 different fragment sizes was detected, 4 "common" and 9 "unusual". Of the latter, 4 were observed only in cancer patients or their first-degree relatives. The frequency of unusual alleles was significantly greater in bladder cancer patients and in the combined tumour group than in controls, thus providing support for the association of unique Ha-ras alleles and cancer. Some unaffected relatives of patients carried unusual alleles, and thus there is no absolute relationship between Ha-ras genotype and disease.

Abstract
Chronic exposure of animals to ethanol leads to changes in membrane lipid composition which may be related to the development of tolerance and physical dependence. The object of the present study was to investigate this phenomenon at a cellular level. HeLa cells were grown in the presence of ethanol (86 mM) for periods of up to 9 days. Both the cholesterol and phospholipid concentration of these cells increased during this period but the cholesterol:phospholipid ratio remained unchanged. Among the phospholipid classes phosphatidic acid decreased while phosphatidylethanolamine, phosphatidylcholine and phosphatidylserine increased rapidly, returning toward control values by 9 days. Significant decreases were observed in saturated (14:0, 16:0) and monoenoic (16:1, 18:1) fatty acids while the major polyenoic fatty acid (20:4) increased. It is concluded that cultured mammalian cells represent a useful model for investigation of the direct effects of ethanol on membrane lipid metabolism.

Abstract
Lysozyme extracted from the egg-white of tortoise, the first example of a reptilian lysozyme to have been purified, has been crystallized and its tertiary structure determined at low resolution by X-ray analysis. This structure is shown to be closely homologous to that of hen egg-white lysozyme. The crystals of tortoise egg-white lysozyme contain a large proportion of liquid and the X-ray map shows that this forms large channels through the crystals into which the active sites of the enzyme molecules open. This indicates that tortois lysozyme crystals may be suitable for low-temperature studies of true enzyme substrate complexes.
