Published: February 2013

AbstractThe Gaia satellite, planned for launch by the European Space Agency (ESA) in 2013, is the next-generation astrometry mission following Hipparcos. Gaia’s primary science goal is to determine the kinematics, chemical structure, and evolution of the Milky Way Galaxy. In addition to this core science goal, the Gaia space mission is expected to discover thousands of Solar System objects. Because of orbital constraints, Gaia will only have a limited opportunity for astrometric follow-up of these discoveries. In 2010, the Gaia Data Processing and Analysis Consortium (DPAC) initiated a program to identify ground-based optical telescopes for a Gaia follow-up network for Solar System Objects to perform the following critical tasks: confirmation of discovery, identification of body, object tracking to constrain orbits. To date, this network comprises 37 observing sites (representing 53 instruments). The Zadko Telescope, located in Western Australia, was highlighted as an important network node because of its southern location, longitude, and automated scheduling system. We describe the first follow-up tests using the fast moving Potentially Hazardous Asteroid 2005 YU55 as the target.

Few studies have investigated the effects of infant nutrition on later bone health in term infants, although low sn-2 palmitate in infant formulas has been shown to result in the formation of stool fatty acid soaps, reduced Ca absorption and lower bone mass in the short term. To investigate the effect of (1) breast-feeding (BF) and (2) the type of infant formula (standard fat blend v. high-sn-2 fat blend) on bone mass at age 10 years, anthropometry and bone mass (from dual-energy X-ray absorptiometry (GE Lunar Prodigy); lumbar spine (LS) and total body less head; adjusted for size (bone mineral apparent density standard deviation score (SDS) and regression)) were measured in 10-year-old subjects born at term and either breast-fed (n 34) or randomised to a standard control formula (n 27) or a high-sn-2 palmitate formula (n 30) for the first 12 weeks of life. At follow-up, previously BF children were older but lighter (by 0·5 SDS, P= 0·03) than formula-fed children with a lower LS bone mineral density SDS (by 0·44, P= 0·03), but size-adjusted bone mass did not differ. There were no significant differences in bone mass between the formula-fed groups. These findings suggest that there is no significant effect of BF or high-sn-2 infant formula on size-adjusted bone mass in mid-childhood, and that the effects of infant nutrition on bone mass previously reported may be confined to the short term. A larger study would be required to exclude smaller effects.
Bacterial carbohydrate-degrading capacity in foal faeces: changes from birth to pre-weaning and the impact of maternal supplementation with fermented feed products

Published: February 2013

The present study aimed at (1) describing age-related changes in faecal bacterial functional groups involved in carbohydrate degradation and in their activities in foals (n10) from birth (day (d) 0) to 6 months (d180) and (2) investigating the effect of maternal supplementation (five mares per treatment) from d − 45 to d60 with fermented feed products on response trends over time of the foal bacterial carbohydrate-degrading capacity. Maternal supplementation with fermented feed products stimulated foal growth from d0 to d60 and had an impact on the establishment of some digestive bacterial groups and their activities in foals from d0 to d5 but not in the longer term. Irrespective of the maternal treatment, total bacteria, total anaerobic, lactate-utilising and amylolytic bacteria were established immediately after birth (P< 0·05) and were active as shown by the significant increase in total volatile fatty acids. In the foals of supplemented mares, total anaerobes and lactate utilisers were established rapidly between d0 and d2 (P= 0·021 and 0·066, respectively) and the increase in the percentage of propionate occurred earlier (P= 0·013). Maternal supplementation had no effect on the establishment of fibrolytic bacteria and their activity. Cellulolytic bacteria andFibrobacter succinogenesfirst appeared at d2 and d5, and increased progressively, reaching stable values at d30 and d60, respectively. From the second week of life, the increase in the molar percentage of acetate and the ratio (acetate+butyrate):propionate (P< 0·05) suggested that fibrolytic activity had begun. From d60, only minor changes in bacterial composition and activities occurred, showing that the bacterial carbohydrate-degrading capacity was established at 2 months of age.

Fibre has been shown to exert a number of benefits on gastrointestinal (GI) health, yet its intake is low. Addition of novel fibres to food products may increase fibre intake and improve gut health. The objective of the present study was to evaluate the influence of three novel fibres on GI outcomes in healthy human subjects. A total of twenty healthy participants (ten men and ten women) with normal BMI (23 (sem 2) kg/m2) participated in the present randomised, double-blind, cross-over study with five treatment periods. Participants consumed a maltodextrin control or 20–25 g/d fibre from soluble maize fibre (SCF) or resistant starch (RS), alone or in combination with pullulan (SCF+P and RS+P). The treatment periods were 7 d with a 3-week washout between the periods. Stool samples were collected on day 7 of each period, and GI tolerance was assessed via a questionnaire on days 1 and 6. There were no treatment differences in stool weight or consistency. SCF significantly reduced stool pH and increased total SCFA production compared with RS and control. RS+P significantly increased the percentage of butyrate compared with all the other treatments. Overall, GI symptoms were minimal. SCF+P led to the highest GI score on day 1, while RS+P had the highest score on day 6. Both SCF treatments caused a significant shift in the gut microbial community. These functional fibres are generally well tolerated, have minimal effects on laxation and may lead to beneficial changes in SCFA production in healthy adults.
Creatine and guanidinoacetate content of human milk and infant formulas: implications for creatine deficiency syndromes and amino acid metabolism
Authors: Edison Erica E. , Brosnan Margaret E. , Aziz Khalid , Brosnan John T. 
Published: February 2013

Creatine is essential for normal neural development; children with inborn errors of creatine synthesis or transport exhibit neurological symptoms such as mental retardation, speech delay and epilepsy. Creatine accretion may occur through dietary intake orde novocreatine synthesis. The objective of the present study was to determine how much creatine an infant must synthesisede novo. We have calculated how much creatine an infant needs to account for urinary creatinine excretion (creatine's breakdown product) and new muscle lay-down. To measure an infant's dietary creatine intake, we measured creatine in mother's milk and in various commercially available infant formulas. Knowing the amount of milk/formula ingested, we calculated the amount of creatine ingested. We have found that a breast-fed infant receives about 9 % of the creatine needed in the diet and that infants fed cows' milk-based formula receive up to 36 % of the creatine needed. However, infants fed a soya-based infant formula receive negligible dietary creatine and must rely solely onde novocreatine synthesis. This is the first time that it has been shown that neonatal creatine accretion is largely due tode novosynthesis and not through dietary intake of creatine. This has important implications both for infants suffering from creatine deficiency syndromes and for neonatal amino acid metabolism.
Inorganic geochemistry of the type Caradoc series (Sandbian to middle Katian, Upper Ordovician), Onny valley, Shropshire, UK
Authors: HANNIGAN R. , BROOKFIELD M. E. 
Published: February 2013

AbstractThe geochemistry and petrology of the type section of the Caradoc Series in the Onny valley indicate that it was deposited on a marginal basin continental shelf similar to the western side of the present Sea of Japan. The lower beds form a transgressive–regressive sequence in which the rocks become less mature upwards. All the coarser sediments above the basal quartzites and conglomerates are greywackes in which the apparent muddy and ferrous matrix is due to the breakdown of unstable minerals and particles. Higher values of Na2O and Na/K ratios are found in the coarser shallow-water sandstones of the Horderley Sandstone Formation and decrease markedly in the succeeding beds, accompanied by an increase in K2O. Higher values of carbonate-corrected (and hence related) other major and minor elements like SiO2, CaO, P2O5, MnO and most trace elements correlate with the transgressive systems and maximum flooding surfaces of the three sequences recognized where they are related to condensation at those horizons. Chemical Indices of Alteration (CIA) suggest that the Horderley Sandstone Formation underwent greater predepositional physical weathering than lower and higher beds, which is compatible with the petrography, and were deposited during a cool phase within overall warm Sandbian–Katian times. Trace element ratios suggest an oxic to suboxic depositional environment.
Religious fundamentalism: a conceptual critique
Authors: McDONOUGH RICHARD 
Published: February 2013

AbstractThe article argues that religious fundamentalism, understood, roughly, as the view that people must obey God's commands unconditionally, is conceptually incoherent because such religious fundamentalists inevitably must substitute human judgement for God's judgement. The article argues, first, that fundamentalism, founded upon the normal sort of indirect communications from God, is indefensible. Second, the article considers the crucial case in which God is said to communicate directly to human beings, and argues that the fundamentalist interpretation of such communications is also incoherent, and, on this basis, argues that religious fundamentalism is actually an extreme form of irreligiousness. Finally, the article considers Kierkegaard's prima facie defence of unconditional religious faith, and argues that, despite some similarity with the fundamentalists, Kierkegaard's appreciation of human finitude leads him to a profoundly anti-fundamentalist stance.

Local identification of spherical buildings and finite simple groups of Lie type
Authors: MEIERFRANKENFELD ULRICH , STROTH GERNOT , WEISS RICHARD M. 
Published: February 2013

AbstractWe give a short proof of the uniqueness of finite spherical buildings of rank at least 3 in terms of the structure of the rank 2 residues and use this result to prove a result making it possible to identify an arbitrary finite group of Lie type from knowledge of its “parabolic structure” alone. Our proof also involves a connection between loops, “Latin chamber systems” and buildings.

AbstractIntroductionThe management of patients with Fontan physiology who undergo scoliosis surgery is difficult. The purpose of this article was to describe our experience in the management of patients with Fontan circulation undergoing spinal surgery for correction of scoliosis.Materials and methodsThis was a retrospective study including patients with Fontan physiology who underwent spinal orthopaedic surgery. Anaesthetic management, post-operative complications, paediatric intensive care unit and total hospital stay, and the need for blood transfusions were analysed.ResultsWe identified eight children with Fontan physiology who had undergone spinal surgery from 2000 to 2010. All patients were receiving cardiac medications at the time of spinal surgery. The mean age at surgery was 14.8 years (range 12–21). In all, three patients needed inotropic support with dopamine (3, 5, and 8 μg/kg/min), which was started during surgery. During the immediate post-operative period, one patient died because of hypovolaemic shock caused by massive bleeding and dysrythmia. Mean blood loss during the post-operative period was 22.2 cc/kg (7.8–44.6). Surgical drainages were maintained for a mean time of 3 days (range 1–7). The mean hospital stay was 9.2 days (range 6–19). Pleural effusions developed in two patients. On follow-up, one patient presented with thoracic pseudarthrosis and another with a serohaematoma of the surgical wound.ConclusionsSpinal surgery in patients with Fontan circulation is a high-risk operation. These patients must be managed by a specialised team.
Ambulance Need at Mass Gatherings
Authors: Meites Elissa , Brown John F. 
Published: February 2013

AbstractIntroduction:Scant evidence exists to guide policy-making around public health needs during mass gatherings. In 2006, the City and County of San Francisco began requiring standby ambulances at all mass gatherings with attendance of >15,500 people. The objectives were to evaluate needs for ambulances at mass gatherings, and to make evidence-based recommendations for public health policy-makers. The hypothesis was that the needs for ambulances at mass gatherings can be estimated using community baseline data.Methods:Emergency medical services plans were reviewed for all public events with an anticipated attendance of >1,000 people in San Francisco County during the 12-month period 01 August 2006 through 31 July 2007. Ambulance transport data were confirmed by event coordinators and ambulance company records, and the rate was calculated by dividing ambulance transports by event attendance. Baseline ambulance transport rate was calculated by dividing the annual ambulance transports in the county's computer-aided dispatch system by the census population estimate. The risk ratio was calculated using the risk of transport from a mass gathering compared with the baseline risk of ambulance transport for the local community. Significance testing and confidence intervals were calculated.Results:Descriptive information was available for 100% of events and ambulance transport data available for 97% of events. The majority of the mass gatherings (47 unique events; 59 event days) were outdoor, weekend festivals, parades, or concerts, though a large proportion were athletic events. The ambulance transport rate from mass gatherings was 1 per 59,000 people every six hours. Baseline ambulance transport rate in San Francisco was 1 per 20,000 people every six hours. The transport rate from mass gatherings was significantly lower than the community baseline (risk ratio [RR] = 0.15, 95% CI = 0.10–0.22, p <0.001). At events reserving a standby ambulance, 46% of ambulances were unused.Discussion:San Francisco mass gatherings appear to present a lower risk of ambulance transports compared to the community baseline, suggesting that the community baseline sets an appropriate standard for requiring standby ambulances at mass gatherings. The initial ambulance requirement policy in San Francisco may have been overly conservative.Conclusions:Local baseline data is a recommended starting point when setting policy for public health needs at mass gatherings.

AbstractDragonfly eye beads are considered to be the earliest types of glass objects in China, and in the past have been considered as evidence of culture interaction or trade between West and East Asia. In this article, synchrotron radiation microcomputed tomography and μ-probe energy dispersive X-ray fluorescence were used to determine the chemical composition, microstructure, and manufacturing technology of four dragonfly eye beads, excavated from a Chu tomb at the Shenmingpu site, Henan Province, China, dated stylistically to the Middle and Late Warring State Period (475 bc–221 bc). First, a nondestructive method was used to differentiate the material types including faience (glazed quartz), frit, glazed pottery (clay ceramic), and glass. Three beads were identified as faience and one bead as glazed pottery. The glaze recipe includes quartz, saltpeter, plant ash, and various copper, and is classified as belonging to the K2O-CaO-SiO2 glass system, which indicates that these beads were not imported from the West. Based on computed tomography slices, the manufacturing technology of the faience eye beads appears to include the use of an inner core, molding technology, and the direct application glazing method. These manufacturing features are consistent with the techniques used in China during this same time period for bronze mold-casting, proto-porcelain, and glass.

AbstractThis study investigated the synthesis of goethite under conditions resembling those of the prebiotic Earth. The artificial seawater used contains all the major elements as well as amino acids (α-Ala, β-Ala, Gly, Cys, AIB) that could be found on the prebiotic Earth. The spectroscopic methods (FT-IR, EPR, Raman), scanning electron microscopy (SEM) and X-ray diffraction showed that in any condition Gly and Cys favoured the formation of goethite, artificial seawater plus β-Ala and distilled water plus AIB favoured the formation of hematite and for the other synthesis a mixture of goethite and hematite were obtained. Thus in general no protein amino acids (β-Ala, AIB) favoured the formation of hematite. As shown by surface enhanced Raman spectroscopy (SERS) spectra the interaction between Cys and Fe3+ of goethite is very complex, involving decomposition of Cys producing sulphur, as well as interaction of carboxylic group with Fe3+. SERS spectra also showed that amino/CN and C-CH3 groups of α-Ala are interacting with Fe3+ of goethite. For the other samples the shifting of several bands was observed. However, it was not possible to say which amino acid groups are interacting with Fe3+. The pH at point of zero charge of goethites increased with artificial seawater and decreased with amino acids. SEM images showed when only goethite was synthesized the images of the samples were acicular and when only hematite was synthesized the images of the samples were spherical. SEM images for the synthesis of goethite with Cys were spherical crystal aggregates with radiating acicular crystals. The highest resonance line intensities were obtained for the samples where only hematite was obtained. Electron paramagnetic resonance (EPR) and Mössbauer spectra showed for the synthesis of goethite with artificial seawater an isomorphic substitution of iron by seawater cations. Mössbauer spectra also showed that for the synthesis goethite in distilled water plus Gly only goethite was synthesized and in artificial seawater plus Cys a doublet due to interaction of iron with artificial seawater/Cys was observed. It should be pointed out that EPR spectroscopy did not show the interaction of iron with artificial seawater/Cys.
The integration of a person-centered approach in palliative care
Authors: Lavoie Mireille , Blondeau Danielle , Martineau Isabelle 
Published: February 2013

AbstractObjective:The philosophy underlying palliative care places the respect of patients and their autonomy at the heart of clinical practice. A study was conducted at a palliative care facility to document changes that occurred after the integration of a person-centered approach focusing on human freedom (which is linked to autonomy): the humanbecoming school of thought. It aimed to describe changes observed in the beliefs and practices of healthcare providers, the concept and respect of autonomy by healthcare providers, care and respect of autonomy experienced by patients' relatives, and consideration of patients' wishes through their documentation.Method:The method adopted consisted of a pre-project – process – post-project descriptive qualitative design and was inspired by teaching-learning and mentoring models. Data were collected from 51 healthcare providers and 10 relatives through semistructured interviews and from the medical records of 30 patients during the pre- and post-project phases. They were analyzed and compared at the end of the study. The process phase consisted of offering training sessions and mentoring, encouraging the involvement of healthcare providers, and cocreating integration and care tools.Results:While the analysis exposed some discrepancies with the language of the approach and differences between nurses and other healthcare providers, it revealed, above all, similarities in the changes observed between the different sources of data. The focus moved from being task-centered to being person-centered; the affirmation of the priority of respecting patients' choices, desires, and needs; a presence shifting from being available to true listening; the affirmation of following the ever-changing rhythm of the patient; and a notion of respect of autonomy now including the other.Significance of results:In line with the philosophy of palliative care, the project demonstrated that the integration of the humanbecoming approach can result in changes that contribute to the development of a more person-centered practice.
