Background: Endovascular thrombectomy (EVT) for ischemic stroke (IS) beyond 6 hours has been proven effective in randomized controlled trials. We present data on implementation and outcomes for EVT beyond 6 hours in Sweden. Methods: We included all cases of anterior circulation IS caused by occlusion of the intracranial carotid artery, and the M1 or M2 segment of the middle cerebral artery, regist

Background Information: Like most other cell surface proteins, α5β1 integrin is glycosylated, which is required for its various activities in ways that mostly remain to be determined. Results: Here, we have established the first comprehensive site-specific glycan map of α5β1 integrin that was purified from a natural source, that is, rat liver. This analysis revealed striking site selective variati

Globally, human population growth, its associated pollution and the vast scale of industrialised fisheries are having negative impacts on oceanic food webs, affecting top predators such as seabirds. We used stable isotope (δ15N and δ13C) analyses of feathers to investigate the contemporary structure and long-term changes in a near-shore community of 5 seabird species in northern Aotearoa New Zeala

Background: A negative oral contrast agent (OCA) has been long sought for, to better delineate the bowel and visualise surrounding structures. Lumentin® 44 (L44) is a new OCA formulated to fill the entire small bowel. The aim of this study was to compare L44 with positive and neutral conventional OCA in abdominal computed tomography (CT). Methods: Forty-five oncologic patients were randomised to r

It is concluded that Melandrium glutinosum Rouy belongs in Sectíott jilisanthe oí Silene. It is certainly a distinct species and ¡ts correct ñame is S. marigii.A description is given. The species is believed to be endemic to the Iberian península and occurs among granite bonlders in the mountains of central Spain and northwest Portugal.Resumen. Se concluye que Melandrium glutinosum pertenece a la

Numerical analyses (multidimensional scaling and Bk non-hierarchic cluster analysis) of wild populations of Silene dioica (L.) CIairv. from Scotland showed a complex pattern of variation, related partly to habitat and partly to geographic location. Subsets of characters- flower/capsule, seed, and vegetative characters- showed discordance, i.e. imperfectly correlated patterns of variation.Material

Silene alba Muhl. ex Britton (1893), although considered to be an illegitimate substitution for S. nivea (Nutt.) Otth, is validly published and as a result S. alba (Miller) E. H. L. Krause (1901), the widely used name for the weed white campion or white cockle, is illegitimate. It is shown that the correct name for this species in Silene is S. pratensis (Rafn) Godron & Gren. A new taxonomic tr

The paper examines how interjections have been treated in linguistic literature; on what grounds they have been separated from pure response cries; and what their relation is to iconic (onomatopoeic) vocabulary items. Second, the paper examines various English grammars intended for university level students, especially in second language contexts, to see how their treatment of interjections reflec

Abstract:A pair of morphologically differentiated sex chromosomes is reported from the Valencian endemic, Silene diclinis. In S. diclinis, the sex chromosomes differ in centromere position, but X and Y chromosomes are approximately equal in length. In the other dioecious species in Silene sect. Elisanthe, the Y chromosome is considerably longer than the X chromosome.Resumen:Se da noticia de un par

Partially Premixed Combustion has shown to be a promising internal combustion concept in terms of engine efficiency and emission levels, however, since the combustion process is partly kinetically controlled, unacceptably high pressure-rise rates could occur at various operating points. A remedy to this problem is the use of a pilot-fuel injection. This paper characterizes double injection effects

For assembly tasks, the knowledge of both trajectory and forces are usually required. Consequently, we may use kinesthetics or teleoperation for recording human demonstrations. In order to have a more natural interaction, the operator has to be provided with a sense of touch. We propose a bilateral teleoperation system which is customized for this purpose. We introduce different coordinate frames
