In this study, several electrocardiogram (ECG)-derived indices corresponding to both ventricular depolarization and repolarization were evaluated during acute myocardial ischemia in an experimental model of myocardial infarction produced by 40 min coronary balloon inflation in 13 pigs. Significant changes were rapidly observed from minute 4 after the start of coronary occlusion, achieving their ma

Dispersal limitation and long-term persistence are known to delay plant species’ responses to habitat fragmentation, but it is still unclear to what extent landscape history may explain the distribution of dispersal traits in present-day plant communities. We used quantitative data on long-distance seed dispersal potential by wind and grazing cattle (epi- and endozoochory), and on persistence (adu

There is a growing gap between tourism's rapidly growing greenhouse gas emissions and the sector's 'aspirational' emission reduction targets as well as the international policy consensus to reduce emissions from this and all other sectors of the economy. The transport component is the largest GHG contributor to the global tourism system. In the absence of supranational policy agreements to curb em

SU-8 is the preferred photoresist for development and fabrication of high aspect ratio (HAR) three dimensional patterns. However, processing of SU-8 is a challenging task, especially when the film thickness as well as the aspect ratio is increasing and the size of the features is close to the resolution limit of photolithography. This paper describes process optimization for the fabrication of den

We present the first measurement of elliptic (v(2)) and triangular (v(3)) flow in high-multiplicity He-3 + Au collisions at root s(NN) = 200 GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in He-3 + Au and in p + p collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observe

Despite the popularity of the social investment approach, there remain ambiguities regarding how to design an effective social investment policy. We review evaluations of conditional cash transfers (CCTs) in Latin America in order to draw out lessons for how to improve the effectiveness of social investment. CCTs share many of the objectives of the social investment approach and are targeted at po

This paper follows directly from an earlier paper where we discussed the requirements for an artifact to be a moral agent and concluded that the artifactual question is ultimately a red herring. As before, we take moral agency to be that condition in which an agent can appropriately be held responsible for her actions and their consequences. We set a number of stringent conditions on moral agency.

To review and update the evidence on predictors of poor outcome (death, persistent vegetative state or severe neurological disability) in adult comatose survivors of cardiac arrest, either treated or not treated with controlled temperature, to identify knowledge gaps and to suggest a reliable prognostication strategy. GRADE-based systematic review followed by expert consensus achieved using Web-ba

The roof dual bound for quadratic unconstrained binary optimization is the basis for several methods for efficiently computing the solution to many hard combinatorial problems. It works by constructing the tightest possible lower-bounding submodular function, and instead of minimizing the original objective function, the relaxation is minimized. However, for higher-order problems the technique has

We show that if R is a, not necessarily unital, ring graded by a semigroup G equipped with an idempotent e such that G is cancellative at e, the nonzero elements of eGe form a hypercentral group and R-e has a nonzero idempotent f, then R is simple if and only if it is graded simple and the center of the corner subring fR(eGe)f is a field. This is a generalization of a result of Jespers' on the sim

The genus Apleurotropis Girault is here reported for the first time from tropical America. The genus is diagnosed and compared to Achrysocharoides Girault with which it shares important characters. Changes are suggested in two existing keys to Neotropical/Nearctic genera of Eulophidae to include Apleurotropis. Included in Apleurotropis are also six newly described species: A. albicaulis, A. albisc

BACKGROUND: Few large-scale studies have examined the association between sociodemographic factors and the probability of reaching the recommended levels of HbA1c and blood lipids in patients with type 2 diabetes. The aim was to investigate whether sociodemographic characteristics of type 2 diabetes patients affected the odds that they would reach recommended levels of blood lipids and HbA1c. METH

AIMS: Atrial fibrillatory rate (AFR) is considered a non-invasive index of atrial remodelling. Low AFR has been associated with favourable outcome of interventions in patients with persistent atrial fibrillation (AF). However, AFR has never been studied in unselected patients with short duration of AF, prone to regain sinus rhythm (SR) spontaneously. The aim of the study was to assess if AFR can p

Background The transanal endorectal one-stage pull-through (TERPT) procedure in children with Hirschsprung disease (HD) is frequently used worldwide. To give the children's families realistic expectations and to plan the medical care for the period after TERPT, the outcome is of great importance. Aim The aim of this article is to collect information on the number of stools passed daily after one-s

Abstract Conclusion: No significant differences in the number of immune aberrations were seen between children with or without severe recurrent acute otitis media (rAOM); however, subnormal values of immunological markers were found more often than expected, and 4 of the 60 children had treatment-requiring immune deficiencies.

The ATLAS detector is used to search for excited leptons in the electromagnetic radiative decay channel l* -> l gamma. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 2.05 fb(-1). No evidence for excited leptons is found, and limits are set on the compositeness scale Lambda as a function of the excited le

In Landspitali University Hospital, magnetic resonance imaging is used non-selectively in addition to mammogram and ultrasound in the preoperative assessment of breast cancer patients. The aim of this study was to assess invasive tumor size on imaging, compare with pathological size and evaluate the impact of magnetic resonance imaging on the type of surgery performed.

[K+(2,2,2-crypt)] Ge-2(9)2- containing the deltahedral Zintl anion Ge-9(2-) has been isolated from a solution of K4Ge9 in ethylenediamine in the presence of 2,2,2-crypt, intended as an intermediate in mixed-cluster synthesis. The subsequent crystallographic characterisation shows the closo-Ge-9(2-) cluster unit to be tricapped trigonal-prismatic with a symmetry very close to D-3h. Each Ge-9(2-) un

Age-related decline in cardiac function can be prevented or postponed by lifelong endurance training. However, effects of normal ageing as well as of lifelong endurance exercise on longitudinal and radial contribution to stroke volume are unknown. The aim of this study was to determine resting longitudinal and radial pumping in elderly athletes, sedentary elderly and young sedentary subjects. Furt
