SummaryTo investigate the relationship between arterial baroreflex sensitivity (BRS) and exercise capacity, we examined arterial BRS and its relation to exercise capacity during upright bicycle exercise in 40 uncomplicated patients with acute myocardial infarction. Arterial BRS was measured 3 weeks (20 ± 5 days) after acute myocardial infarction and assessed by calculating the regression line relating phenylephrine‐induced increases in systolic blood pressure to the attendant changes in the R–R interval. All patients underwent graded symptom‐limited bicycle exercise with direct measurements of hemodynamic and metabolic measurements. In all patients, the average arterial BRS was 5·6 ± 2·6 ms mmHg−1. There were no significant correlations between arterial BRS and hemodynamic measurements at rest. However, arterial BRS was negatively related to systemic vascular resistance at peak exercise (r = −0·60, P = 0·0001) and percent change increase in systemic vascular resistance from rest to peak exercise (r = −0·45, P = 0·003), whereas arterial BRS was positively related to cardiac output (r = −0·48, P = 0·002) and stroke volume at peak exercise (r = 0·42, P = 0·007), and percent change increase in cardiac output (r = −0·55, P = 0·0002) and stroke volume from rest to peak exercise (r = 0·41, P = 0·008). Furthermore, arterial BRS had modest but significant correlations with peak oxygen consumption (r = −0·48, P = 0·002) and exercise duration (r = 0·35, P = 0·029), indicating that patients with better arterial BRS have better exercise capacity in patients with acute myocardial infarction. These results suggest that arterial BRS was linked to central and peripheral hemodynamic responses to exercise and hence, contributed to exercise capacity after acute myocardial infraction.

Lian, O. B. & Hicock, S. R. 2009: Insight into the character of palaeo‐ice‐flow in upland regions of mountain valleys during the last major advance (Vashon Stade) of the Cordilleran Ice Sheet, southwest British Columbia, Canada. Boreas, 10.1111/j.1502‐3885.2009.00123.x. ISSN 0300‐9483.A detailed glacial geological study was done on Vashon till, formed during the last (Fraser) glaciation, in upland areas of two relatively short and narrow mountain valleys which open onto the Fraser Lowland in southwest British Columbia. The orientation and association of glaciotectonic structures in till and bedrock, a‐axis fabrics of stones in till and abrasion features, indicate that Vashon till formed initially by lodgement and that brittle deformation processes dominated at least during the latter stages of glaciation. The presence of local glacigenic bedrock quarrying suggests that ice flow experienced localized enhanced compressive flow along valley sides. These observations indicate that ice flow was relatively slow and they contrast with a previous study of bedrock geomorphology undertaken in some larger south Coast Mountains valleys and a model of ice‐flow velocity in the Puget Lowland that suggest rapid ice flow. This indicates that either ice‐flow conditions in the larger valleys were different from those in the valleys studied here, or that the observations from our study reflect subglacial conditions following the Last Glacial Maximum (LGM), but immediately prior to deglaciation when ice had thinned and slowed. If the latter scenario is correct, and if processes inferred from this study were also common along the upland parts of other southwest Coast Mountains valleys after the LGM, then the rate at which ice was supplied to lowland piedmont glaciers would have been reduced, and this may have accelerated decay of the southwest margin of the last Cordilleran Ice Sheet.

Johnson, M. D. & Ståhl, Y. 2009: Stratigraphy, sedimentology, age and palaeoenvironment of marine varved clay in the Middle Swedish end‐moraine zone. Boreas, 10.1111/j.1502‐3885.2009.00124.x. ISSN 0300‐9483Deglaciation of the Middle Swedish end‐moraine zone and age of the sediment in and between the moraines have been discussed for about a hundred years. The goal of this project was to determine the stratigraphy and age of the sediment in and between the moraines. Inter‐moraine flats are underlain by clay, 10–25 m thick, overlying thin sand and gravel or till on bedrock. The clay is overlain by a few metres of sand and gravel. Much of the clay beneath the flats consists of rhythmites that grade from grey to red and are 2–74 cm thick. Our interpretation of these rhythmites as being varves is supported by grain size and mineralogical and elemental variations. Foraminifera and ostracods show that the clay was deposited in an arctic marine environment, while radiocarbon dating of the microfossils indicates that the clay was deposited 12 150 cal. 14C years ago, during the Younger Dryas chronozone (YD). Most of the optical stimulated luminescence dates on the clay are much older, containing quartz sand that was insufficiently bleached. The stratigraphy indicates that the moraines are composed of YD clay pushed into ridge forms during ice‐front oscillations. It is not possible to determine how far north the Scandinavian Ice Sheet retreated prior to the YD advance. We neither support nor reject the suggestion that the ice margin retreated to the northern edge of Mt. Billingen during the Allerød, causing the Baltic Ice Lake to drain.

AbstractLow serum cholesterol has long been associated with hemorrhagic stroke even though the mechanism for this association has yet to be elucidated. The association of low serum cholesterol with hemorrhagic stroke has been described thus far only in adult studies. There have been no reports of this association in children. We present a case of a hemorrhagic stroke that occurred in a 6‐year‐old, severely malnourished child who had just received augmentation of cardiac output with a pulsatile left ventricular assist device.

AbstractCleveland Clinic's PediPump (Cleveland, OH, USA) is a ventricular assist device designed for the support of pediatric patients. The PediPump is a mixed‐flow ventricular assist device with a magnetically suspended impeller measuring 10.5 mm in diameter by 64.5 mm in length. Progress and achievements for the PediPump program are considered according to the development project's three primary objectives: Basic engineering: along with size reductions, substantial design improvements have been incorporated in each design iteration including the motor, magnetic bearings, axial touch points, and heat transfer path; Anatomic modeling and device fitting studies: Techniques based on computed tomography and magnetic resonance imaging have been developed to create three‐dimensional anatomic‐modeling and device‐fitting tools to facilitate device implantation and to assist in preoperative planning. For in vivo testing, to date, six acute (6‐h duration) and nine chronic (30‐day target duration) implantations have been performed in sheep; the implantation of the PediPump appears to be relatively easy with excellent hemodynamic performance and minimal hemolysis during support. Cleveland Clinic's PediPump program supported by the National Heart, Lung and Blood Institute's Pediatric Circulatory Support Program has led to the development of a pediatric ventricular assist device that has satisfactory performance in preclinical evaluation and appears to be ready to support a program of clinical testing.

OBJECTIVES: To determine the frequency of cholinesterase inhibitor (ChEI) use in nursing home (NH) residents with dementia and examine correlates of ChEI use in this population.DESIGN: Cross‐sectional study using the 2004 National Nursing Home Survey (NNHS).SETTING: A representative, stratified, random sample of U.S. NHs.PARTICIPANTS: All NNHS participants aged 65 and older with a chart diagnosis of dementia.MEASUREMENTS: Bivariate analyses to compare characteristics of NH residents with dementia according to ChEIs status and multivariable logistic regression to identify independent correlates of ChEI use.RESULTS: Almost half (49.1%) of NNHS participants had dementia, and 30.0% of those with dementia were receiving ChEIs. Donepezil accounted for 71% of all ChEI prescriptions. Multivariable logistic regression showed that ChEI use was independently associated with younger age (odds ratio (OR)=0.42, 95% confidence interval (CI)=0.28–0.64, aged ≥95 vs 65–74), less activity of daily living impairment (OR=0.49, 95% CI=0.42–0.58, severe vs mild impairment), greater use of antipsychotics (OR=1.33, 95% CI=1.16–1.54) and antidepressants (OR=1.38, 95% CI=1.20–1.59), and residence in NHs with more beds (OR=1.52, 95% CI=1.07–2.16, ≥200 beds vs <50 beds).CONCLUSION: Approximately 30% of NH residents with dementia in U.S. NHs are treated with ChEIs. Functional impairment and medical comorbidity are common in ChEIs users, although users tend to be younger and less impaired than NH residents with dementia who are not receiving ChEIs. Further study is required to determine the optimum use of ChEI in NH populations.

OBJECTIVES:To examine whether hearing acuity correlates with walking ability and whether impaired hearing at baseline predicts new self‐reported walking difficulties after 3 years.DESIGN:Prospective follow‐up.SETTING:Research laboratory and community.PARTICIPANTS:Four hundred thirty‐four women aged 63 to 76.MEASUREMENTS:Hearing was measured using clinical audiometry. A person was defined as having a hearing impairment if a pure‐tone average of thresholds at 0.5 to 4 kHz in the better ear was 21 dB or greater. Maximal walking speed was measured over 10 m (m/s), walking endurance as the distance (m), covered in 6 minutes and difficulties in walking 2 km according to self‐report.RESULTS:At baseline, women with hearing impairment (n=179) had slower maximal walking speed (1.7 ± 0.3 m/s vs 1.8 ± 0.3 m/s,P=.007), lower walking endurance (520 ± 75 m vs 536 ± 75 m,P=.08), and more selfreported major difficulties in walking 2 km (12.8% vs 5.5%,P=.02) than those without hearing impairment. During follow‐up, major walking difficulties developed for 33 participants. Women with hearing impairment at baseline had a twice the age‐adjusted risk for new walking difficulties as those without hearing impairment (odds ratio=2.04, 95% confidence interval=0.96–4.33).CONCLUSION:Hearing acuity correlated with mobility, which may be explained by the association between impaired hearing and poor balance and greater risk for falls, both of which underlie decline in mobility. Prevention of hearing loss is not only important for the ability to communicate, but may also have more wide‐ranging influences on functional ability.

OBJECTIVES: To examine the prevalence and sociodemographic and health‐related correlates of substance use, including alcohol, tobacco, and nonmedical drug use, in adults aged 65 and older.DESIGN: Cross‐sectional, retrospective survey of a population‐based sample, the 2001/02 National Epidemiologic Survey on Alcohol and Related Conditions.SETTING: United States.PARTICIPANTS: Eight thousand two hundred five U.S. adults aged 65 and older.MEASUREMENTS: Prevalence of lifetime and previous‐12‐month alcohol, tobacco, and nonmedical drug use and associations between substance use and sociodemographic and health‐related factors.RESULTS: Almost 80% of older adults had used any of the three substances over their lifetimes, and more than 50% reported such use over the previous 12 months. Alcohol was the most commonly used substance over the lifetime (74%) and in the previous 12 months (45%), followed by tobacco (52% lifetime; 14% previous 12 months); far fewer reported nonmedical use of drugs (5% lifetime; 1% previous 12 months). In general, being younger, male, and divorced or separated were factors consistently associated with use of any of the three substances.CONCLUSION: Most older adults had used substances over their lifetimes and in the previous 12 months. Alcohol is the substance of choice for this age group, followed by tobacco; few report nonmedical drug use.

OBJECTIVE: To assess the effect of gynecological surgery on mobility and functional status in women aged 60 and older using Life‐Space Assessment (LSA).DESIGN: Observational prospective cohort study.SETTING: Academic outpatient urogynecology and gynecological oncology clinics.PARTICIPANTS: Women presenting for urogynecology (n=51) and gynecological oncology (n=51) surgery.MEASUREMENTS: LSA scores 6 weeks, 6 months, and 1 year after surgery. Information on participant demographics, preoperative diagnoses, surgical approach, and medical comorbidities was collected. Analyses used repeated measures.RESULTS: Mean age was 71 ± 7. Urogynecology participants started and maintained a higher LSA (P=.03) than oncology participants at all study intervals. Six weeks after surgery, urogynecology and oncology participants' mean decline was 13 points (95% confidence interval (CI)=4–21; P=.004) and 23 points (95% CI=13–33; P<.001), respectively. At 6 months, the urogynecology and oncology participants' scores increased by a mean of 9 points (95% CI=1–17; P=.03) and 13 points (95% CI=5–20; P=.001), respectively. No significant difference was found 1 year from baseline within each group or between groups in LSA scores. Income, depression, body mass index, and having an operative complication predicted a larger decline in life‐space over time in both groups.CONCLUSION: Gynecological surgical interventions in older women limit physical and functional ability at 6 weeks after surgery. The urogynecology and gynecological oncology cohorts returned to baseline levels by 6 months, which was sustained to 1 year.

An individual, whose parents are third cousins, has been shown to be homozygous for the rare Mi.V. condition. The proposita's red blood cells type as M−, N+(weak), S−, s+(strong), U+, Mi(a−), Vw−, Hil+; Wr(a− b−). The cells react, albeit less strongly than most other samples, with anti‐Ena. However, from studies on the red blood cells of the proposita and on those of another person of the En(a+), Wr(a−b−) phenotype, it is apparent that the term “anti‐Ena” actually describes a number of antibodies of differing specificities. Inhibition studies with sialoglycoprotein (SGP) isolates, and tests on protease‐modified red blood cells illustrate some of the differences in specificity.Biochemical analyses of the SGPs of the red blood cells of the MiV homozygote and those of her parents confirm that the Mi.V condition is associated with the absence of normal MN SGP (α) and normal Ss SGP (δ), the appearance of a hybrid SGP molecule comprised of a portion of the MN SGP at its NH2 terminal end, and a portion of the Ss SGP at its C terminal end.
The Theology of Jean Daniélou: Epochs, Correspondences, and the Orders of the Real
Authors: Nichols Aidan 
Published: October 2009

AbstractAfter a survey of the life and work of Jean Daniélou considered as the classic theologian of twentieth century ‘ressourcement’, his theological method is explored under three headings: ‘epochs’ indicates his reliance on the theology of history as developed by ‘biblical theology’; ‘correspondences’ his cosmic aesthetics, indebted to French Symbolism, and invoked theologically by way of typology; ‘orders’ his Pascalian emphasis on a distinction between levels of reality and the variety of epistemological approaches they require. The article concludes by applying Daniélou's method, so understood, to the heart of his theological doctrine, his account of God in Jesus Christ.
Am I divine?
Authors: Göcke Benedikt Paul 
Published: October 2009

AbstractOn the one hand, arguably, I am neither this nor that. Arguably, neither is God this or that – so, am I God? Otherwise it seems that I must be this and God must be that. On the other hand, the being of the universe is not something of which I could plausibly be construed as the ultimate cause. That is God's creative act. Because I do not create the universe, I am not God. So I am God and I am not God. Here's a solution: God is One but also Three, I am but one.
The Enchantment of Stanley Spencer
Authors: Tester Keith 
Published: October 2009

AbstractIn the early 1930s the artist Stanley Spencer committed himself to working on the never-achieved Church-House project. It was intended to reflect his understanding of God and religion as love, and, furthermore, of the sacred being fully integrated in secular times and places. The first painting he finished for the project was Villagers and Saints (1933), now in the collection of the University of Hull. This paper uses Villagers and Saints as a way into a reading of Spencer's work, drawing on insights from Charles Taylor's A Secular Age to explore how Spencer sacramentalises the material world. The first part of the paper contextualises Villagers and Saints, and the second part identifies its vision with what appears to have been a conversion experience, discussed by Spencer in his public writing.
Travel with a Time Lord: using media to enhance literacy
Authors: Harrett Jacqueline , Benjamin Theresa 
Published: October 2009

AbstractThis article reports on a UKLA‐funded project in which a group of 10 teachers in South Wales were involved. The televised science fiction drama Doctor Who was chosen as the theme as it was based on popular culture as well as being of local and national interest. The main character in this television drama is an alien who can fly through time and space in a machine called the Tardis. The aim of the project was to improve standards in literacy, with writing as a particular focus and make teachers more aware of the effective use of media resources. Teachers were provided with an information pack containing sample lessons but were actively encouraged to implement the project in whichever way they chose. Questionnaires given to teachers before and after the project reflected a more positive attitude towards using media resources at the end. Pupils, aged between 8 and 11 years old, were given writing journals as part of the project and focus groups interviewed. It proved difficult to ascertain if standards had improved although pupil enthusiasm was a recognisable feature. The value of learning across the curriculum was another element that emerged during the course of the project. Results indicated that more training is required to enable teachers to use media resources and cross‐curricular approaches more confidently in their teaching.
Pre‐service teachers explore cultural identity and ideology through picture books
Authors: Hammett Roberta , Bainbridge Joyce 
Published: October 2009

AbstractThis paper draws on early data from a cross‐Canada research project in which researchers at six Faculties of Education have been engaged in introducing picture books with multiple and diverse representations of Canadians to classes of pre‐service teachers, inviting them to explore the pedagogical possibilities of the picture books and to discuss their cultural identities in focus groups and interviews. The paper reports the participants' expressed understandings of multiculturalism and their own relations and experiences with it, as well as their thoughts on classroom implementation of curriculum that incorporates picture books with multicultural and diversity themes. The paper also includes a case study of one Canadian province to further explore the wider context of pre‐service teachers' understandings and ideologies by examining discourses in policy and practices in Newfoundland and Labrador.
Sampling Effects and Host Ranges in Australian Mistletoes
Authors: Grenfell Matt , Burns Kevin C. 
Published: October 2009

ABSTRACTThe number of host species utilized by Australian mistletoe species increases with their geographic range sizes. Rather than resulting from deterministic processes, we demonstrate that this pattern results from wider‐ranging species being sampled more efficiently, and we discuss how sampling effects might be addressed in future analyses of mistletoe biogeography.
