Do people cope with situations as they say? Relationship between perceived coping style and actual coping response
Authors: Shikai Noriko , Nagata Toshiaki , Kitamura Toshinori 
Published: October 2013

AimThe coping style that individuals think they will use when encountering stressful situations may differ from actual coping response in real situations.MethodsIn a longitudinal study on some 500 university students, perceived coping style was identified using the Coping Inventory for Stressful Situations on the first occasion. In the subsequent eight test occasions, which occurred on a weekly basis, the students were asked about a negative life event that occurred during the past week and the actual coping responses they used.ResultsThe perceived coping style and the actual coping response matched well for task‐oriented and emotion‐oriented coping. For avoidance‐oriented coping, however, perceived coping style and actual coping response were weakly correlated.ConclusionEpidemiological studies on coping and mental health should discriminate coping style and coping response. Clinicians should be cautious about patients' own information about avoidance‐oriented coping.

Published: October 2013

AbstractAccurate and objective measurement of volume changes in infantile hemangiomas (IHs) is essential in routine clinical practice and clinical studies, particularly in the changing therapeutic landscape after the discovery of propranolol. Several bedside techniques for volume measurement have been described in the literature, but an objective method of measurement of this variable, dynamic vascular tumor is lacking. Three‐dimensional (3D) phototechnology with data analysis is an up‐and‐coming technique in the objective measurement of facial volume changes. In this pilot study, the usability and clinical relevance of two methods of 3D stereophotogrammetry in the volume measurement of IH were explored.

AbstractHUS is characterized by hemolytic anemia, thrombocytopenia, and acute renal failure. While “typical” HUS is usually associated with Shiga toxin‐producing Escherichia coli infections and recovers in the majority of cases, aHUS is caused by mutations of complement components or antibodies against CFH leading to uncontrolled activation of alternative complement pathway and often to ESRD. Recently, THBD gene mutations have been reported in aHUS. Theoretically, the risk of disease recurrence after renal transplantation should be low because THBD is primarily a membrane‐bound protein expressed by endothelial cells; however, a small proportion of THBD is present as a soluble form in plasma. We report the case of a 19‐yr‐old man with aHUS secondary to a THBD mutation that relapsed twice after two renal transplantations performed 12 yr apart. Despite successful control of HUS with plasma exchange and eculizumab after the second transplantation, the graft was ultimately lost due to severe steroid‐resistant cellular rejection. The present report suggests that THBD mutations may favor‐relapse of aHUS after renal transplantation.

AbstractEMB, the gold standard for diagnosis of ACR, poses unique risks in children. Limited cross‐sectional data have associated LV MPI with ACR. We hypothesize that a relative change in MPI from baseline without ACR to the time of ACR will better detect ACR than an absolute threshold LV MPI value. We identified 40 children with ACR ≥60 days post‐transplant matching them by age and time from transplantation to 40 children without ACR. There was a significant increase in LV MPI at time of ACR vs. baseline (0.59 ± 0.17 vs. 0.41 ± 0.11; p < 0.001). There was no difference in LV MPI between baseline and follow‐up (0.41 ± 0.11 vs. 0.42 ± 0.11; p = 0.65). An absolute increase in LV MPI of ≥0.47 had 82.5% sensitivity and 85% specificity for ACR, whereas an increase in LV MPI from baseline of ≥20.4% was 90% sensitive and 100% specific. Serial measurement of LV MPI appears to be a sensitive and specific marker of ACR. LV MPI shows good interobserver agreement and increases at the time of EMB‐proven ACR with subsequent resolution to baseline measurements upon EMB‐proven resolution of ACR. Future studies in larger, prospective cohorts should be undertaken to validate these findings.

AbstractObjectivesThe objectives of the study were to use persona‐driven and scenario‐based design methods to create a conceptual information system design to support public health nursing.Design and SampleWe enrolled 19 participants from two local health departments to conduct an information needs assessment, create a conceptual design, and conduct a preliminary design validation.MeasuresInterviews and thematic analysis were used to characterize information needs and solicit design recommendations from participants. Personas were constructed from participant background information, and scenario‐based design was used to create a conceptual information system design. Two focus groups were conducted as a first iteration validation of information needs, personas, and scenarios.ResultsEighty‐nine information needs were identified. Two personas and 89 scenarios were created. Public health nurses and nurse managers confirmed the accuracy of information needs, personas, scenarios, and the perceived usefulness of proposed features of the conceptual design. Design artifacts were modified based on focus group results.ConclusionPersona‐driven design and scenario‐based design are feasible methods to design for common work activities in different local health departments. Public health nurses and nurse managers should be engaged in the design of systems that support their work.

Published: October 2013

AbstractObjectiveDespite research that suggests parental communication may help deter high‐risk sexual behavior among adolescents, parents report a lack of confidence in their ability to answer sexually related questions. The purpose of this study was to test the effect of a multimedia intervention on outcome expectations and perceived self‐efficacy for the sex educator role for parents of African American adolescent males.Design and SampleA pilot study using mixed methods was conducted. A nonprobability sample (N = 61) was obtained from a large urban community using a combination of convenience and snowball recruitment methods.MeasuresSelf‐efficacy and outcome expectations were measured using self‐reported questionnaires.InterventionA multimedia intervention for use at home and incorporating an audio CD and associated activities was implemented over a 3‐week time period.ResultsOutcome expectations and self‐efficacy both significantly improved after the intervention (p < .001).ConclusionsFindings indicate that using a multimedia approach may be effective in improving parents' outcome expectancy and self‐efficacy for talking about sex with adolescent sons.
Substituent Effect on the Photolability of 4‐Aryl‐1,4‐Dihydropyridines

Published: October 2013

AbstractThe electronic nature of substituents attached to the 4‐aryl moiety of 1,4‐dihydropyridines strongly affects the photophysical and photochemical behavior of these family of compounds. The presence of an electron donor substituent on the 4‐aryl moiety (or the absence of electron‐withdrawing ones) modifies the luminescence lifetimes (τ < 100 ps) and diminishes the photodecomposition quantum yields. For electron‐withdrawing substituents, the photodegradation quantum yield is affected by the media, changing more than two orders of magnitude as the polarity is increased. Studies in micellar media allow us to conclude that 4‐aryl‐1,4‐dihydropyridines are located near to the interface; however, the surface charge of micelles has no effect on the photodegradation rate constant or the photoproducts profile. The main conclusion of this work is that the photolability of 4‐aryl‐1,4‐dihydropyridines can be significantly reduced by the incorporation of antioxidant moieties.
Spectral and Spatial UV Sky Radiance Measurements at a Seaside Resort Under Clear Sky and Slightly Overcast Conditions
Authors: Sandmann Henner , Stick Carsten 
Published: October 2013

AbstractSpatial measurements of the diffusely scattered sky radiance at a seaside resort under clear sky and slightly overcast conditions have been used to calculate the sky radiance distribution across the upper hemisphere. The measurements were done in the summer season when solar UV radiation is highest. The selected wavelengths were 307, 350 and 550 nm representing the UVB, UVA and VIS band. Absolute values of radiance differ considerably between the wavelengths. Normalizing the measured values by use of direct solar radiance made the spatial distributions of unequal sky radiance comparable. The results convey a spatial impression of the different distributions of the radiance at the three wavelengths. Relative scattered radiance intensity is one order of magnitude greater in UVB than in VIS, whereas in UVA lies roughly in between. Under slightly overcast conditions scattered radiance is increased at all three wavelengths by about one order of magnitude. These measurements taken at the seaside underline the importance of diffuse scattered radiance. The effect of shading parts of the sky can be estimated from the distribution of sky radiance. This knowledge might be useful for sun seekers and in the treatment of people staying at the seaside for therapeutic purposes.
Genetic diversity and population structure of Lantana camara in India indicates multiple introductions and gene flow
Authors: Ray A. , Quader S. 
Published: October 2013

AbstractLantana camara is a highly invasive plant, which has spread over 60 countries and island groups of Asia, Africa and Australia. In India, it was introduced in the early nineteenth century, since when it has expanded and gradually established itself in almost every available ecosystem. We investigated the genetic diversity and population structure of this plant in India in order to understand its introduction, subsequent range expansion and gene flow. A total of 179 individuals were sequenced at three chloroplast loci and 218 individuals were genotyped for six nuclear microsatellites. Both chloroplasts (nine haplotypes) and microsatellites (83 alleles) showed high genetic diversity. Besides, each type of marker confirmed the presence of private polymorphism. We uncovered low to medium population structure in both markers, and found a faint signal of isolation by distance with microsatellites. Bayesian clustering analyses revealed multiple divergent genetic clusters. Taken together, these findings (i.e. high genetic diversity with private alleles and multiple genetic clusters) suggest that Lantana was introduced multiple times and gradually underwent spatial expansion with recurrent gene flow.

AbstractThe storage of fruits and vegetables under a controlled atmosphere can induce low oxygen stress, which can lead to post‐harvest losses through the induction of disorders such as core breakdown and browning. To gain better understanding of the metabolic response of plant organs to low oxygen, cultured tomato cells (Lycopersicum esculentum) were used as a model system to study the metabolic stress response to low oxygen (0 and 1 kPa O2). By adding 13C labelled glucose, changes in the levels of polar metabolites and their 13C label accumulation were quantified. Low oxygen stress altered the metabolite profile of tomato cells, with the accumulation of the intermediates of glycolysis in addition to increases in lactate and sugar alcohols. 13C label data showed reduced label accumulation in almost all metabolites except lactate and some sugar alcohols. The results showed that low oxygen stress in tomato cell culture activated fermentative metabolism and sugar alcohol synthesis while inhibiting the activity of the TCA cycle and the biosynthesis of metabolites whose precursors are derived from central metabolism, including fluxes to most organic acids, amino acids and sugars.

In China, the incidence of phoma stem canker observed in pre‐harvest surveys from 2005 to 2012 was greater on winter oilseed rape in provinces in central China (in May) than on spring oilseed rape in north China (in August). In all 742 cases when the causal pathogen was isolated from stem cankers, it was identified as Leptosphaeria biglobosa by morphology in culture and/or by species‐specific polymerase chain reaction. Both L. biglobosa and Leptosphaeria maculans were detected on crop debris and seed in shipments of oilseed rape seed imported into China through Shanghai or Wuhan ports in 2009–2011. Descriptions of the observed spread of L. maculans into areas previously colonized by L. biglobosa across a spring oilseed rape growing region (Alberta, Canada, westwards, 1984–1998) and across a winter oilseed rape growing region (Poland, eastwards, 1984–2004) were used to estimate the potential westward spread of L. maculans in China across spring oilseed rape growing regions (north China) and winter oilseed rape growing regions (central China, generally provinces along the Yangtze River), respectively. The rates of spread were estimated as 47 km per year across spring oilseed rape in north China and 70 km per year across winter oilseed rape in central China. Dispersal modelling suggested that the rate of spread of L. maculans across Alberta, Canada (c. 17 km per year) could be explained by windborne dispersal of ascospores.

AbstractEucalyptus plantations are among the most productive forest stands in Portugal and Spain, being mostly used for pulp production and, more recently, as an energy crop. However, the region's Mediterranean climate, with characteristic severe summer drought, negatively affects eucalypt growth and increases mortality. Although the physiological response to water shortage is well characterized for this species, evidence about the plants' recovery ability remains scarce. In order to assess the physiological and biochemical response of Eucalyptus globulus during the recovery phase, two genotypes (AL‐18 and AL‐10) were submitted to a 3‐week water stress period at two different intensities (18 and 25% of field capacity), followed by 1 week of rewatering. Recovery was assessed 1 day and 1 week after rehydration. Drought reduced height, biomass, water potential, NPQ and gas exchange in both genotypes. Contrarily, the levels of pigments, chlorophyll fluorescence parameters (Fv/Fm and φPSII), MDA and ABA increased. During recovery, the physiological and biochemical profile of stressed plants showed a similar trend: they experienced reversion of altered traits (MDA, ABA, E, gs, pigments), while other parameters did not recover (φPSII, NPQ). Furthermore, an overcompensation of CO2 assimilation was achieved 1 week after rehydration, which was accompanied by greater growth and re‐establishment of oxidative balance. Both genotypes were tolerant to the tested conditions, although clonal differences were found. AL‐10 was more productive and showed a more rapid and dynamic response to rehydration (namely in carotenoid content, φPSII and NPQ) compared to clone AL‐18.

SummaryThis paper describes a new diatom species, Aulacoseira calypsi Tremarin, Torgan & Ludwig, from specimens in plankton samples from Água Preta lake. This Amazonian lake is a shallow mesotrophic environment situated in northern Brazil. The species is characterized by long filaments united by spatulate linking spines, obovate to conic separation spines, a valve surface variably ornamented, straight striae on the mantle, a narrow ringleist, and one row of sessile rimoportulae near the ringleist. Aulacoseira calypsi's morphometric features are compared with the following similar species: Aulacoseira nygaardii (Camburn) Camburn & Charles, Aulacoseira lacustris (Grunow) Krammer, Aulacoseira coroniformis Pearce & Cremer, Aulacoseira occulta Siver & Hamilton, Aulacoseira lancea Siver & Hamilton, Aulacoseira gessneri (Hustedt) Simonsen, and Aulacoseira islandica (Müller) Simonsen. The species shares similarities as to frustule size, striation pattern, and narrowness of ringleist; but differs in the morphology of separation and linking spines, and the number and position of the rimoportulae.

AbstractBackgroundCataract affects not only vision, but also performance of everyday tasks, participation in social activities, quality of life and possibly depression. Depression is a major health issue for older adults. It is estimated that 6%–20% of community‐dwelling older Australians experience depression. The aim of this study was to investigate changes in vision‐related quality of life and depressive symptoms after first eye cataract surgery and to determine which visual measures affect the change in these outcomes.MethodsIn 2009 and 2010, 99 participants with bilateral cataract were recruited. Visual measures including visual acuity, contrast sensitivity and stereopsis were assessed 1 week before and 12 weeks after first eye cataract surgery. Vision‐related quality of life was measured using the 25‐item National Eye Institute Visual Function Questionnaire. Depressive symptoms were assessed by the 20‐item Center for Epidemiological Studies Depression Scale. Separate regression analyses were undertaken to determine the association between visual measures and changes in vision‐related quality of life and depressive symptoms after first eye cataract surgery.ResultsOverall, vision‐related quality of life improved after first eye cataract surgery. There was a small, non‐clinically significant improvement in depressive symptoms after surgery. Improvement in vision‐related quality of life after first eye cataract surgery was associated with improved contrast sensitivity in the operated eye (P < 0.001), whereas improvement in depressive symptoms after surgery was associated with improved stereopsis (P = 0.032).ConclusionsContrast sensitivity and stereopsis, but not visual acuity, were significant factors affecting improvement in vision‐related quality of life or depressive symptoms after first eye cataract surgery.
Effect of synchronized or desynchronized music listening during osteopathic treatment: An EEG study

Published: October 2013

AbstractWhile background music is often used during osteopathic treatment, it remains unclear whether it facilitates treatment, and, if it does, whether it is listening to music or jointly listening to a common stimulus that is most important. We created three experimental situations for a standard osteopathic procedure in which patients and practitioner listened either to silence, to the same music in synchrony, or (unknowingly) to different desynchronized montages of the same material. Music had no effect on heart rate and arterial pressure pre‐ and posttreatment compared to silence, but EEG measures revealed a clear effect of synchronized versus desynchronized listening: listening to desynchronized music was associated with larger amounts of mu‐rhythm event‐related desynchronization (ERD), indicating decreased sensorimotor fluency compared to what was gained in the synchronized music listening condition. This result suggests that, if any effect can be attributed to music for osteopathy, it is related to its capacity to modulate empathy between patient and therapist and, further, that music does not systematically create better conditions for empathy than silence.
Auditory startle reflex inhibited by preceding self‐action

Published: October 2013

AbstractA startle reflex to a startle pulse is inhibited when preceded by a prestimulus. We introduced a key‐press action (self‐action) or an 85 dB noise burst as a prestimulus, followed by a 115 dBnoise burst as a startle pulse. We manipulated temporal offsets between the prestimulus and the startle pulse from 30–1,500 ms to examine whether self‐action modulates the startle reflex and the temporal properties of the modulatory effect. We assessed eyeblink reflexes by electromyography. Both prestimuli decreased reflexes compared to pulse‐alone trials. Moreover, the temporal windows of inhibition were different between the types of prestimuli. A faster maximal inhibition and narrower temporal window in self‐action trials suggest that preceding self‐action inhibits the startle reflex and allows prediction of the coming pulse in different ways from auditory prestimuli.
Irrealism and the Genealogy of Morals
Authors: Joyce Richard 
Published: October 2013

AbstractFacts about the evolutionary origins of morality may have some kind of undermining effect on morality, yet the arguments that advocate this view are varied not only in their strategies but in their conclusions. The most promising such argument is modest: it attempts to shift the burden of proof in the service of an epistemological conclusion. This paper principally focuses on two other debunking arguments. First, I outline the prospects of trying to establish an error theory on genealogical grounds. Second, I discuss how a debunking strategy can work even under the assumption that noncognitivism is true.
