Elevation and topography influence community structure, biomass and host tree interactions of lianas in tropical montane forests of southern Ecuador
Authors: Fadrique Belén , Homeier Jürgen 
Published: June 2016

AbstractQuestionsHow does the structure of liana communities (diameter, density and biomass) in tropical montane forests vary along elevation and topographic gradients? How do patterns of tree infestation vary with elevation? Is tree diameter growth reduced by lianas in tropical montane forest?LocationTropical Andean forests (1000–3000 m a.s.l.) in the San Francisco Reserve and in the Podocarpus National Park, southern Ecuador.MethodsAll lianas (DBH ≥ 1 cm) were censused in 54 permanent plots (20 × 20 m) equally distributed between three study sites (1000, 2000 and 3000 m a.s.l.) and three topographic positions (lower, mid and upper slope) per site (six replicate plots at each site by position combination). The DBH and number of lianas hosted was recorded for all trees (DBH ≥ 10 cm). Liana biomass was estimated using allometric equations. ANOVAs were used to test for effects of elevation and slope positions on liana parameters and proportion of trees infested. The relationships between liana biomass and tree parameters and environmental parameters were analysed with partial least squares regression. We used the available literature data to perform a regression analysis of liana biomass in response to elevation in humid tropical old‐growth forests between sea level and 3000 m a.s.l.ResultsLiana diameter, density and biomass all decrease with elevation. The decreasing liana biomass agrees with results from previous studies of liana biomass in other humid tropical forests, indicating a decrease of 0.18 Mg·ha−1 liana biomass per 100 m of elevation gain. Topographic variation leads to thinner but more abundant stems upslope; there was no effect of topographic position on liana biomass. Liana biomass and liana infestation are both positively correlated with host tree DBH at every elevation. Tree diameter growth is reduced by liana infestation; the proportion of infested trees is lower in Andean montane forests than in tropical lowland forests.ConclusionsLiana biomass distribution and tree infestation vary significantly with elevation. Biomass of lianas and relative contribution of lianas to total above‐ground biomass both decrease with elevation. Topographic effects likely result from higher soil fertility at lower slope positions.

ObjectivesSonouroflowmetry represents a novel method for estimating urinary flow parameters. The aim of this study was to compare the urinary flow parameters acquired using sonouroflowmetry with those of standard uroflowmetry in healthy female volunteers.MethodsThirty‐six healthy female volunteers (aged 25–54 years) were subjected to standard uroflowmetry. Simultaneously, subjects dialed a dedicated number on a mobile phone and kept recording until urination was finished. Sound data were analyzed and compared to the uroflowmetry data. Of 218 recordings, 183 were included in the final analysis. Thirty‐four measurements were excluded for voided volume <150 mL or technical problems during the recording. A linear model was fitted to calculate the urinary flow parameters and the voided volume from data obtained by sonouroflowmetry. Subsequently the matching datasets of UF and SUF were compared with respect to flow time, voided volume, maximum (Qmax) and average (Qave) flow rate. Pearson's correlation coefficient (PCC) was used to compare parameters recorded by uroflowmetry with those calculated based on sonouroflowmetry recordings.ResultsA strong correlation (PCC = 0.95) was noted between uroflowmetry recorded flow time and duration of the sonouroflowmetry sound signal. The voided volume measured by uroflowmetry showed a moderate correlation (PCC = 0.68) with the calculated area under the sonouroflowmetry curve. Qmax recorded using uroflowmetry and sonouroflowmetry recorded peak sound intensity showed a weak correlation (PCC = 0.38).ConclusionsThis study validates the basic concept of using sound analysis to estimate urinary flow parameters and voided volume.

SummaryWe report an outbreak of dermatophytoses in rabbits, which was the origin of a dermatophytose epidemic in an agricultural school in central Portugal, affecting 15 people. Both the phenotypic characteristics and internal transcribed spacer (ITS) sequence of the dermatophytes isolated from the rabbits and patients were identical, suggesting that a single strain was responsible for both the epizootic and epidemic dermatophytoses and confirming that these two outbreaks were linked. The ITS sequences were also 100% identical to the ITS sequence of five strains isolated from rabbits in Greece and Italy, but different from that of Trichophyton mentagrophytes commonly isolated from dogs and cats. These results suggest that a particular T. mentagrophytes genotype could be prevalent in rabbits in southern Europe.

SummaryIntroductionHigh blood pressure (BP) in childhood is associated with left ventricular hypertrophy and abnormal vascular reactivity even in apparently healthy children. This study examined the prevalence of high BP in children undergoing elective noncardiac operations. We also determined the association of preoperative high BP with preincision hypotension (PIH).MethodsThis was a retrospective cohort study that used clinical and anthropometric data on children aged 3–17 years who underwent elective, noncardiac operations from January 2006 to January 2014. Preoperative blood pressure (BP) was used to stratify children into three categories: normal BP (systolic and diastolic BP below the 90th percentile), prehypertension (systolic and/or diastolic BP ≥90th percentile but <95th percentile or if the BP exceeds 120/80 mmHg even if it is below the 90th percentile), and hypertension (systolic and/or diastolic BP ≥95th percentile). Multivariable logistic regression analysis was used to calculate adjusted odds ratios for PIH using age, gender, body mass index (BMI), and BP categories as covariates.ResultsAmong 35832 children, the overall prevalence of prehypertension, hypertension, and hypertension by adult standards were 16.4%, 6.8%, and 3.3%, respectively. Overweight and obese children had higher rates of elevated BP. Presence of elevated baseline BP, high BMI category, and presence of OSA diagnosis were independent predictors of multiple episodes of PIH in a logistic regression model.ConclusionIn children, preoperative high BP is an independent predictor of PIH. Although the longtime consequences of high BP are well known, this report provides the first intraoperative evidence of adverse event associated with preoperative high BP in children. Mechanisms underlying this hypotensive response are unclear.

A collection of 102 Diaporthe isolates was compiled from lesions on carrot, parsley and wild Apiaceae species in France from 2010 to 2014. Molecular typing based on ITS rDNA sequences resulted in the identification of 85 D. angelicae and 17 D. eres isolates. Based on sequences of the 3′ part of the IGS rDNA, intraspecific variability was analysed for 17 D. angelicae and 13 D. eres isolates from diverse plant species, locations in France, and plant tissues. The genetic diversity was greater for D. angelicae isolates than D. eres isolates. In vitro sensitivity of five D. angelicae and four D. eres isolates to each of nine fungicides was similar for isolates of both species, with a marked variation in fungicide sensitivity depending on the active ingredient. To assess the pathogenicity of D. angelicae and D. eres isolates on carrot, one isolate of each species was inoculated onto umbels in a controlled environment. Typical lesions were observed for both isolates. Carrot crop debris collected from a seed production field in France and placed in controlled conditions produced perithecia and ascospores typical of Diaporthe, that were further characterized molecularly as belonging to D. angelicae. Detection of Diaporthe species on seed lots from three carrot production fields in France was investigated. Both species were detected on seeds by conventional PCR assay, with a greater frequency for D. angelicae than D. eres (67% vs 33%, respectively). Overall, the results highlighted that umbel browning in carrot seed crops in France was mainly caused by D. angelicae.
Quantifying lip‐read‐induced suppression and facilitation of the auditory N1 and P2 reveals peak enhancements and delays
Authors: Baart Martijn 
Published: June 2016

AbstractLip‐read speech suppresses and speeds up the auditory N1 and P2 peaks, but these effects are not always observed or reported. Here, the robustness of lip‐read‐induced N1/P2 suppression and facilitation in phonetically congruent audiovisual speech was assessed by analyzing peak values that were taken from published plots and individual data. To determine whether adhering to the additive model of AV integration (i.e., A+V ≠ AV, or AV−V ≠ A) is critical for correct characterization of lip‐read‐induced effects on the N1 and P2, auditory data was compared to AV and to AV−V. On average, the N1 and P2 were consistently suppressed and sped up by lip‐read information, with no indication that AV integration effects were significantly modulated by whether or not V was subtracted from AV. To assess the possibility that variability in observed N1/P2 amplitudes and latencies may explain why N1/P2 suppression and facilitation are not always found, additional correlations between peak values and size of the AV integration effects were computed. These analyses showed that N1/P2 peak values correlated with the size of AV integration effects. However, it also became apparent that a portion of the AV integration effects was characterized by lip‐read‐induced peak enhancements and delays rather than suppressions and facilitations, which, for the individual data, seemed related to particularly small/early A‐only peaks and large/late AV(−V) peaks.

AbstractThe profile of a river that conveys sediment without net deposition and net erosion is referred to as ‘graded’ with respect to vertical aggradation of the river segment. Three experimental series, designed in terms of the autostratigraphic view of alluvial grade, were conducted to clarify the diagnostic spatial behaviour of graded alluvial–deltaic rivers: an ‘R series’, which utilized a moving boundary setting with a stationary base level; an ‘F series’ in a fixed boundary setting with a stationary base level to produce ‘forced grade’; and an ‘M series’ in a moving boundary setting with constant base‐level fall to produce ‘autogenic grade.’ The results of the three experimental series, combined with geometrical modelling of the effects of basin water depth and other experimental data, suggest the following: (i) in a graded alluvial–deltaic system, lateral shifting and avulsing of active distributary channels are suppressed regardless of whether the downstream boundary of the deltaic system is fixed; (ii) in a delta with a downstream‐fixed boundary, the graded streams are stabilized within a valley that is incised in the axial part of the delta plain, whereby the alluvial plain outside the valley is abandoned and terraced; (iii) in moving boundary settings, the graded river simply extends basinward as a linearly elongated channel and lobe system without cutting a valley; and (iv) a modern forced‐graded alluvial river is most likely to be found in a valley incised into a fan delta in front of very deep water, and the stratigraphic signal of fossil autogenic‐graded rivers will be found in deltaic successions that accumulated in the outer to marginal areas of deltaic continental shelves during sea‐level falls. This renewed autostratigraphic view of alluvial grade suggests a thorough reconsideration of the conventional understanding that an alluvial river feeding a progradational delta is graded with a stationary base level.
On facies belts and facies mosaics: Holocene isolated platforms, South China Sea
Authors: Rankey Eugene C. 
Published: June 2016

AbstractAlthough the general criteria for recognition and environmental interpretation of different carbonate facies are well‐established, a predictive understanding of the areal extent and spatial patterning of facies bodies and why they might organize into facies belts or facies mosaics is poorly constrained. To explore patterns and process dynamics of facies on isolated carbonate platforms, quantitative analysis of thematic maps derived from remote sensing images of 27 Holocene atolls of the Paracel and Spratly chains in the South China Sea explores variability within and among platforms. On these systems, most annular shelf‐margin reefs are less than 500 m wide on both chains; inboard of the reefs, reef sand aprons range up to 500 m (Spratlys) and 1000 m (Paracels) wide. Around individual platforms, Spratly Chain sand apron widths are wider to the north‐west, whereas apron widths in the Paracel Chain are more symmetrical; collectively, data indicate log‐normal width‐exceedance probability distributions. Platform‐interior patch reefs include area‐exceedance probability distributions and gap size distributions (lacunarity) consistent within chains, but distinct between the chains. To understand the processes underlying distinct distributions, simulations explored distinct growth scenarios. Results suggest that differences may represent distinct process classes: proportional growth processes with multiplicative random effects (reef sand aprons – belts), versus non‐linear, size‐proportional growth of randomly aged and distributed elements (patch reefs – mosaics). The probabilistically distinct sizes and spatial patterns of geomorphic elements within these general process classes are interpreted to represent ‘variations on themes’ related to the different impacts of tropical storms, winter cold fronts and circulation in each chain. The results highlight fundamentally different growth patterns impacting the sizes and distribution of facies belts and mosaics on isolated carbonate platforms. Because these types of bodies ultimately construct stratigraphy, the themes could be applied to understand and predict variability in the architecture of subsurface reservoir analogues.
The Patient Protection and Affordable Care Act Meets the ‘Persistently Uninsured’
Authors: Williams Jackson 
Published: June 2016

AbstractUnder the Patient Protection and Affordable Care Act (commonly known as ‘Obamacare’), the national uninsured rate has fallen from 17.3 per cent in 2013 to 11.7 per cent in the first half of 2015. While this is a substantial drop, even accounting for the states that did not expand Medicaid, the remaining double‐digit national rate, as well as higher rates in some states, indicates that a significant minority of Americans are not buying insurance. Researchers have identified a segment of the population with weak or uncertain preferences for health insurance. This article explores how such individuals are unevenly distributed across states and whether cultural preferences relating to time preference and risk aversion underlie the geographic distribution of the ‘persistently uninsured’. It concludes by reviewing the policy implications presented by the presence of numerous health insurance sceptics in certain jurisdictions.
Why Health Care Reform Now? Strategic Framing and the Passage of Obamacare
Authors: Leimbigler Betsy , Lammert Christian 
Published: June 2016

AbstractEconomic reform and health care reform were both focal points outlined in President Obama's policy agenda, with increasing pressure to address economic and social insecurity given that President Obama entered office during the Great Recession (2007–09). The Patient Protection and Affordable Care Act (commonly known as ‘Obamacare’) successfully passed in March 2010 in the context of the economic crisis. We argue that the strategic framing of the economic crisis, through reasoning and arguments linking health care reform with economic downfall, is important in understanding the successful passage of Obamacare, and that this is reflected through strategic frames in speeches delivered by the President on health care reform. Health care reform has been successful not in spite of but rather because of the economic crisis of 2008, that allowed President Obama to use a strategic frame focusing on costs and economic problems. The two main frames identified are the ‘market’ and ‘rights’ frames. President Obama's strategic frames specifically surrounding the economic and cost‐containment priority of health care reform are categorized as a ‘market’ frame in this article. He used this frame until the passage of the law in 2010, when the frame shifted to ‘rights’ frames, largely portrayed through anecdotes and focused on the concept of ‘access’ to care rather than the ‘cost’ of care. This is observable through tracking speeches and statements made in support of health care reform between 2009 and 2013.

BackgroundSkin disease can negatively affect the Quality of Life (QoL) of cats and of their owners.ObjectivesTo develop and evaluate a questionnaire on QoL of cats with skin disease and their owners.MethodsFollowing interviews with owners of cats with severe skin disease and elaboration of a preliminary 19 item questionnaire, a final 15 item (score 0–3) questionnaire was developed. This was administered to owners of 45 cats with allergic dermatitis and 39 healthy cats, to assess its ability to differentiate between diseased and healthy subjects. In allergic cats, owners evaluated overall disease severity (S) and pruritus with a Visual Analog Scale (VAS); veterinarians evaluated skin lesions [SCORing Feline Allergic Dermatitis (SCORFAD) and Feline Dermatitis Extent and Severity Index (FeDESI)]. The correlation with QoL was analysed by Spearman's rank test. In 31 allergic cats, SCORFAD, FeDESI, pruritus VAS, S and QoL scores were obtained before and after therapy, and their improvement evaluated statistically.ResultsQoL scores in allergic cats were significantly higher than in healthy cats (P=<0.0001). Severity correlated well and significantly with both cat's and owner's QoL (r = 0.51 and 0.64, P = 0.0003 and <0.0001, respectively). Correlation of QoL with pruritus VAS was moderate and significant (r = 0.3, P = 0.03), whereas with SCORFAD and FeDESI it was low and not significant. With therapy all scores decreased significantly (P < 0.0001); however, QoL was not influenced by improvement of clinical scores. Questions related to the burden of therapy showed the smallest improvements.ConclusionsThis QoL questionnaire could be a useful tool in evaluating cats with skin disease.
Revisiting Frank–Starling: regulatory light chain phosphorylation alters the rate of force redevelopment (ktr) in a length‐dependent fashion
Authors: Toepfer Christopher N. , West Timothy G. , Ferenczi Michael A. 
Published: June 2016

Key points
Regulatory light chain (RLC) phosphorylation has been shown to alter the ability of muscle to produce force and power during shortening and to alter the rate of force redevelopment (ktr) at submaximal [Ca2+].
Increasing RLC phosphorylation ∼50% from the in vivo level in maximally [Ca2+]‐activated cardiac trabecula accelerates ktr.
Decreasing RLC phosphorylation to ∼70% of the in vivo control level slows ktr and reduces force generation.
ktr is dependent on sarcomere length in the physiological range 1.85–1.94 μm and RLC phosphorylation modulates this response.
We demonstrate that Frank–Starling is evident at maximal [Ca2+] activation and therefore does not necessarily require length‐dependent change in [Ca2+]‐sensitivity of thin filament activation.
The stretch response is modulated by changes in RLC phosphorylation, pinpointing RLC phosphorylation as a modulator of the Frank–Starling law in the heart.
These data provide an explanation for slowed systolic function in the intact heart in response to RLC phosphorylation reduction.
AbstractForce and power in cardiac muscle have a known dependence on phosphorylation of the myosin‐associated regulatory light chain (RLC). We explore the effect of RLC phosphorylation on the ability of cardiac preparations to redevelop force (ktr) in maximally activating [Ca2+]. Activation was achieved by rapidly increasing the temperature (temperature‐jump of 0.5–20ºC) of permeabilized trabeculae over a physiological range of sarcomere lengths (1.85–1.94 μm). The trabeculae were subjected to shortening ramps over a range of velocities and the extent of RLC phosphorylation was varied. The latter was achieved using an RLC‐exchange technique, which avoids changes in the phosphorylation level of other proteins. The results show that increasing RLC phosphorylation by 50% accelerates ktr by ∼50%, irrespective of the sarcomere length, whereas decreasing phosphorylation by 30% slows ktr by ∼50%, relative to the ktr obtained for in vivo phosphorylation. Clearly, phosphorylation affects the magnitude of ktr following step shortening or ramp shortening. Using a two‐state model, we explore the effect of RLC phosphorylation on the kinetics of force development, which proposes that phosphorylation affects the kinetics of both attachment and detachment of cross‐bridges. In summary, RLC phosphorylation affects the rate and extent of force redevelopment. These findings were obtained in maximally activated muscle at saturating [Ca2+] and are not explained by changes in the Ca2+‐sensitivity of acto‐myosin interactions. The length‐dependence of the rate of force redevelopment, together with the modulation by the state of RLC phosphorylation, suggests that these effects play a role in the Frank–Starling law of the heart.
