AbstractBackgroundPostoperative complications still comprise the marker used most frequently to assess the quality of gastrectomy. However, the definition and grading of morbidity is not standardized, hampering meaningful comparisons over time and among centers. This study proposes specific definitions and a reproducible classification of complications following gastrectomy using standardized grading tools.MethodsWe defined each complication based on the literature, and adopted the Accordion Severity Grading System to stratify morbidity. The classification was applied to 890 patients with gastric cancer seen between January 2010 and April 2011. The correlation between the complication grades and the length of hospital stay (LOS) was analyzed, and risk factors for complications were examined with special reference to severity grade.ResultsThe overall morbidity rate was 18.1 %. Mild complications occurred in 31 patients (3.5 %), moderate in 77 patients (8.7 %), severe—invasive procedure/no general anesthesia (GA) in 27 patients (3.0 %), severe—invasive procedures/GA in 18 patients (2.0 %), and severe—organ failure in 3 patients (0.3 %). Five patients (0.6 %) died postoperatively. The grade of complications had a significant effect on the LOS (p < 0.001). Operating time and cardiovascular and pulmonary co‐morbidities were independent risk factors for severe complications [odds ratio (OR) 1.001, p = 0.016; OR 2.226, p = 0.006; OR = 2.896, p = 0.003, respectively].ConclusionsThe complications after gastrectomy could be classified into different severity grades that had distinct clinical outcomes. The use of this classification provides more reliable, practical outcome data. Consequently, complications should be reported using a standardized classification tool such as the Accordion Severity Grading System, which requires consensus on the definition of specific complications.
Neuronal representation of number and proportion in the primate brain
Authors: Vallentin D. , Jacob · S.N. , Nieder A. 
Published: July 2012

Abstract
Number symbols have allowed humans to develop superior mathematical skills that are a hallmark of technologically advanced cul­tures. Findings in animal cognition, devel­opmental psychology, and anthropology in­dicate that these numerical skills are rooted in nonlinguistic biological primitives. Recent studies in human and nonhuman primates using a broad range of methodologies pro­vide evidence that numerical information is represented and processed by regions of the prefrontal and posterior parietal lobes, where single neurons are tuned to preferred abso­lute quantities. Until recently, data explor­ing ratios of quantities, as in proportions and fractions, were comparatively sparse. New data derived with complementary methods and from different model systems now shed light on the mechanisms of magnitude ra­tio representations. A coding scheme for pro­portions has emerged that is highly reminis­cent of the representation of absolute num­ber. The magnitude code is automatic, inde­pendent of language and the format of pre­sentation. These findings suggest that the primate brain houses a phylogenetically old network for the representation of quantity that, during the course of human evolution, has been coopted to build our remarkable sense of number.
Structural and functional maturation of presynaptic nerve endings under the control of transsynaptic signalling
Authors: Wittenmayer Nina , Dresbach Thomas 
Published: July 2012

Abstract
Synapse assembly is the cellular mechanism that mediates the generation of physical con­nections between nerve cells and, thus, al­lows for the establishment of functional con­nectivity in the brain. The biogenesis of a syn­apse requires a set of highly coordinated mo­lecular events, ranging from initial forma­tion of adhesive contacts between an axon and a dendrite, followed by the recruitment and precise arrangement of synaptic organ­elles and proteins on both sides of the syn­aptic cleft, and culminating in the mainte­nance and remodelling of the exquisite archi­tecture of a differentiated, i.e. mature, synap­tic junction. Both the postsynaptic and the presynaptic compartment are thought to un­dergo stages of maturation that change and shape synaptic structure and function in a characteristic way. Recent evidence suggests that transsynaptic signalling, elicited by post­synaptic cell adhesion molecules, regulates the molecular events underlying presynap­tic maturation. Thus, synaptic cell adhesion molecules, apart from physically connecting nerve cells, emerge as coordinators of presyn­aptic and postsynaptic differentiation across the synaptic cleft.
COMPARATIVE PHOTOSYNTHESIS, WATER RELATIONS, GROWTH AND SURVIVAL RATES IN JUVENILE CRIOLLO CACAO CULTIVARS (THEOBROMA CACAO) DURING DRY AND WET SEASONS

Published: July 2012

SUMMARYThis study deals with the ecophysiological response of Criollo cacao cultivars to water deficit during initial establishment phase in an agroforestry system under shade of four timber species using a randomised block design. CO2 assimilation rate (A), transpiration (E) and stomatal conductance (gs), water potentials, pressure–volume curves and fluorescence measurements were studied during two dry and wet seasons. Survival rates, basal diameter and leaf concentrations of K, P and N were also determined. All cultivars exhibited 60% reduction in gs with drought, resulting in 73% decrease in A and E. Despite lower A, electron-transport rates were not significantly affected, suggesting the existence of electron sinks. Photochemical quenching is negatively affected by drought in some cultivars, whereas relative quantum yield of photosystem II and non-photochemical quenching remained the same during both the periods. Cultivars with the highest osmotic adjustment coincided with the highest survival rates, whereas growth and leaf nutrient concentrations were similar in all cultivars.
On the essential spectrum of phase-space anisotropic pseudodifferential operators
Authors: MĂNTOIU MARIUS 
Published: July 2012

AbstractA phase-space anisotropic operator in=L2(ℝn) is a self-adjoint operator whose resolvent family belongs to a naturalC*-completion of the space of Hörmander symbols of order zero. Equivalently, each member of the resolvent family is norm-continuous under conjugation with the Schrödinger unitary representation of the Heisenberg group. The essential spectrum of such a phase-space anisotropic operator is the closure of the union of usual spectra of all its “phase-space asymptotic localizations”, obtained as limits over diverging ultrafilters of ℝn×ℝn-translations of the operator. The result extends previous analysis of the purely configurational anisotropic operators, for which only the behavior at infinity in ℝnwas allowed to be non-trivial.
Externalizing problems, attention regulation, and household chaos: A longitudinal behavioral genetic study

Published: July 2012

AbstractPrevious research documented a robust link between difficulties in self-regulation and development of externalizing problems (i.e., aggression and delinquency). In this study, we examined the longitudinal additive and interactive genetic and environmental covariation underlying this well-established link using a twin design. The sample included 131 pairs of monozygotic twins and 173 pairs of same-sex dizygotic twins who participated in three waves of annual assessment. Mothers and fathers provided reports of externalizing problems. Teacher report and observer rating were used to assess twin's attention regulation. The etiology underlying the link between externalizing problems and attention regulation shifted from a common genetic mechanism to a common environmental mechanism in the transition across middle childhood. Household chaos moderated the genetic variance of and covariance between externalizing problems and attention regulation. The genetic influence on individual differences in both externalizing problems and attention regulation was stronger in more chaotic households. However, higher levels of household chaos attenuated the genetic link between externalizing problems and attention regulation.
Toward a new understanding of legacy of early attachments for future antisocial trajectories: Evidence from two longitudinal studies
Authors: Kochanska Grazyna , Kim Sanghag 
Published: July 2012

AbstractEarly parent–child attachment has been extensively explored as a contributor to children's future adaptive or antisocial outcomes, but the specific developmental mechanisms remain to be fully understood. We examined long-term indirect developmental sequelae of early security in two longitudinal community samples followed from infancy to early school age: the Family Study (102 mothers, fathers, and infants) and the Parent–Child Study (112 mothers and infants). Constructs at multiple levels (child characteristics, parent–child security, parental discipline, and child antisocial outcomes) were assessed using a range of methods (extensive behavioral observations in a variety of settings, informants' ratings). Both studies supported the proposed model of infant attachment as a potent catalyst that moderates future developmental socialization trajectories, despite having few long-term main effects. In insecure dyads, a pattern of coercion emerged between children who were anger prone as toddlers and their parents, resulting in parents' increased power-assertive discipline. Power assertion in turn predicted children's rule-breaking conduct and a compromised capacity to delay in laboratory paradigms, as well as oppositional, disruptive, callous, and aggressive behavior rated by parents and teachers at early school age. This causal chain was absent in secure dyads, where child anger proneness was unrelated to power assertion, and power assertion was unrelated to antisocial outcomes. Early insecurity appeared to act as a catalyst for the parent–child dyad embarking on a mutually adversarial path toward antisocial outcomes, whereas security defused such a maladaptive dynamic. The possible mechanisms of those effects were proposed.
Do pathological gambling and obsessive-compulsive disorder overlap? a neurocognitive perspective

Published: July 2012

ObjectivePathological gambling (PG) is a severe and persistent pattern of problem gambling that has been aligned with obsessive-compulsive disorder (OCD). However, no study has compared the neurocognitive profiles of individuals with PG and OCD.MethodsWe compared neurocognitive functioning, including executive function, verbal learning and memory, and visual–spatial organization and memory among 16 pathological gamblers, 31 drug-naïve OCD subjects, and 52 healthy controls.ResultsThe only neurocognitive marker common to both groups was increased fragmentation errors on the Rey–Osterrieth Complex Figure Test (ROCF). The PG subjects showed increased nonperseverative error on the Wisconsin Card Sorting Test and organization difficulties in the ROCF, whereas the OCD subjects revealed longer response times on the Stroop test and retention difficulties on the immediate recall scale of the ROCF.ConclusionsA more careful approach is required in considering whether PG is a part of the OCD spectrum, as little evidence of neurocognitive overlap between PG and OCD has been reported.

AbstractObjectiveTo evaluate plant sterol intake estimated with the eighty-four-item Northern Sweden FFQ against repeated 24 h dietary recalls (24-HDR) as the reference method.DesignRandomly recruited participants from the Västerbotten Intervention Programme (VIP) responded to an FFQ (FFQ1). Over the subsequent 12 months, ten repeated 24-HDR were carried out. After this, a second FFQ (FFQ2) was completed.SettingVästerbotten county, northern Sweden.SubjectsNinety-six men and ninety-nine women.ResultsThe Pearson correlation coefficient for absolute total plant sterol intake estimated with FFQ1 and 24-HDR was 0·58 and 0·55 for the men and women, respectively. Cross-classification of participants into quartiles of absolute plant sterol intake estimated with FFQ1 and 24-HDR showed that 90 % of the men and 83 % of the women were classified into the same or an adjacent quartile. For energy-adjusted plant sterol intake, 71 % of the men and 74 % of the women were classified into the same or an adjacent quartile. The agreement for cross-classification of participants into quartiles between FFQ1 and FFQ2 was good for both absolute and energy-adjusted plant sterol intake.ConclusionsThe FFQ is able to capture absolute plant sterol intake to the same extent as other nutrients, and to rank individuals according to both their absolute and energy-adjusted plant sterol intake. The reproducibility of the FFQ was good, suggesting that the method is reliable. This makes it possible to use plant sterol data from the FFQ in large-scale studies of the association between plant sterol intake and disease.
WITHDRAWN: Global CO2 Storage Potential of Self‐Sealing Marine Sedimentary Strata
Authors: Eccles Jordan K , Pratson Lincoln 
Published: July 2012

AbstractInjection of CO2 below the seafloor into sedimentary strata where pressures and temperatures would trap the CO2 through “self‐sealing” gravitational and hydrate‐formation mechanisms has received little interest after analyses of a selection of deep‐sea sediment cores suggested that such storage would not likely be feasible. Attention with respect to offshore CO2 storage has since shifted to the possibility of injecting CO2 into sub‐seafloor basalt layers embedded within impermeable strata. Here we re‐examine the storage potential of self‐sealing marine sedimentary strata using a more comprehensive, global dataset of deep‐sea sediment cores, heat flow measurements, bathymetry, and sediment thickness maps. In contrast to previous reports, we find the CO2 storage potential of these strata to be abundant. We map out the worldwide distribution and thicknesses of self‐sealing marine sedimentary strata, which we estimate to have a total bulk sediment volume of 63 million cubic kilometers. Of this, roughly 1.3–2.7% may prove suitable for CO2 storage. This storage is unevenly distributed where it lies within the Exclusive Economic Zones (EEZ) of the world's largest CO2 emitting economies. The United States and India respectively release 16% and 62% of their annual CO2 emissions (or 1 Bt/y and 800 Mt/y) within 500 km of self‐sealing strata located in their EEZs, while only 6% of the annual emissions from China and the European Union (or 330 Mt/y and 250 Mt/y, respectively) occur within this distance.
Revealing forerunners on Envisat's wave mode ASAR using the Global Seismic Network

Published: July 2012

Swells radiating across ocean basins are fingerprints of the large ocean storms that generated them, which are otherwise poorly observed. Here we analyze the signature of one swell event in the seismic noise recorded all around the Pacific and we show that it is a natural complement to the global coverage provided by the Synthetic Aperture Radar wave mode data from ENVISAT. In particular the seismic stations are much more sensitive to low frequency and amplitude signals than buoys and SAR, capturing swell forerunners a couple of days before they can be detected from space or in situ data. This information helps detect in the SAR measurements the presence of very long swell, with periods of 22 s in our case example, that were otherwise excluded.

Quantity, Structure, and Habitat Selection of Natural Spawning Reefs by Walleyes in a North Temperate Lake: A Multiscale Analysis
Authors: Raabe Joshua K. , Bozek Michael A. 
Published: July 2012

AbstractSpawning habitat, the cornerstone of self‐sustaining, naturally reproducing walleye Sander vitreus populations, has received limited quantitative research. Our goal was to quantitatively describe the structure and quantity of natural walleye spawning habitat and evaluate potential selection of habitat in Big Crooked Lake, Wisconsin. In 2004 and 2005, we located and delineated walleye egg deposition polygons through visual snorkel and scuba surveys. We also delineated recently deposited, adhesive egg patches daily along one spawning reef in 2005. To determine habitat selection, we quantified and compared spawning and lakewide available habitat at different scales. In both years, walleyes used similar spawning habitat, including three geomorphic types: linear shorelines, a point bar, and an island. Walleyes used only 14% of the entire lake shoreline and 39% of the shoreline comprised of gravel (6.4–76.0 mm), cobble (76.1–149.9 mm), or coarser substrates for spawning in 2005, indicating selection of specific spawning habitat. Lakewide, walleyes spawned close to shore (outer egg deposition polygon boundary mean distance = 2.7 m), in shallow water (outer egg deposition polygon boundary mean depth = 0.3 m), and over gravel substrate (percent coverage mean = 64.3) having low embeddedness (mean = 1.30). Our best nearshore (0–13‐m) resource selection function predicted an increase in the relative probability of egg deposition with the increasing abundance of gravel, cobble, and rubble (150.0–303.9‐mm) substrates and a decrease with increasing distance from shore and water depth (89.9% overall correct classification). Adhesive egg patches confirmed that walleyes actively chose nearshore, shallow‐water, and coarse‐substrate spawning habitat. The quantitative habitat information and predictive models will assist biologists in developing walleye spawning reef protection strategies and potentially aid in designing and evaluating artificial spawning reefs.
The Economic Value of Catching and Keeping or Releasing Saltwater Sport Fish in the Southeast USA
Authors: Carter David W. , Liese Christopher 
Published: July 2012

Abstract
To evaluate the economic effects of bag limit and minimum size regulations, it is important to understand how anglers’ valuation of catch varies. Using a sportfishing demand model, we estimated angler willingness to pay (WTP) for groupers Epinephelus spp. and Mycteroperca spp., red snapper Lutjanus campechanus, dolphinfish Coryphaena hippurus, and king mackerel Scomberomorus cavalla by using data from a choice experiment survey with questions about fishing trips in the southeast USA. Beyond differentiating by species and the number of fish caught (second through sixth), our catch disposition model separately estimated angler WTP for one additional fish caught and kept, caught and released due to a minimum size limit, and caught and released due to a bag limit. Angler valuations of groupers, red snapper, and king mackerel were similar and more than five times the angler valuation of dolphinfish. For all species, the angler valuation decreased with each successive fish. For red snapper and groupers, anglers indicated that keeping a fish was worth more than eight times the value of releasing the fish due to a bag limit. For all species except king mackerel, angler WTP did not differ much between a fish released due to a bag limit and a fish released due to a size limit. For king mackerel, the value of a fish caught and released due to a bag limit was more than 2.5 times the value of a fish released due to a size limit and was nearly half the value of a fish that was caught and kept. We compared our angler WTP values with those in the literature, and we provide a policy application example. Results suggest that measures of the economic effects of sportfishing regulations can be seriously misstated if the species, number, and disposition of the catch are not considered.
