Outcome after endovascular therapy of ruptured intracranial aneurysms: morbidity and impact of rebleeding
We evaluated midterm functional outcome after endovascular occlusion of aneurysms in patients with subarachnoid haemorrhage (SAH) and determined the incidence of late rebleeding as an additional prognostic parameter. We treated 79 consecutive patients with SAH from an intracranial aneurysm admitted from a neurological intensive care unit by the endovascular route between 1993 and 1997 and 52 survi
Precise matching of olivo-cortical divergence and cortico-nuclear convergence between somatotopically corresponding areas in the medial C1 and medial C3 zones of the paravermal cerebellum
The paravermal cerebellar cortex contains three spatially separate zones (the C1, C3 and Y zones) which form a functionally coupled system involved in the control of voluntary limb movements. A series of 'modules' has been postulated, each defined by a set of olivary neurons with similar receptive fields, the cortical microzones innervated by these neurons and the group of deep cerebellar nuclear
Remodeling of fracture callus in mice is consistent with mechanical loading and bone remodeling theory
During the remodeling phase of fracture healing in mice, the callus gradually transforms into a double cortex, which thereafter merges into one cortex. In large animals, a double cortex normally does not form. We investigated whether these patterns of remodeling of the fracture callus in mice can be explained by mechanical loading. Morphologies of fractures after 21, 28, and 42 days of healing wer
Hyperthermia dough: a fat and bone equivalent phantom to test microwave/radiofrequency hyperthermia heating systems
The recipe described gives an easy to prepare, easy to handle and inexpensive fat phantom for the determination of absorbed-power distributions of microwave/radiofrequency radiation. If the phantom is used together with the high-water-content phantom (Guy 1971) the absorbed-power distributions can be determined in structured tissues. The phantom has been used in Utrecht to test the e-m boundary co
Rapid resolution of EPO-induced pure red cell aplasia after a course of immunoadsorption therapy using protein a columns
Pure red cell aplasia (PRCA) is a rare, but important, complication of erythropoietin (EPO) replacement therapy in patients with renal disease. There is no consensus about the best way to treat this condition; however, recent reports indicated that immunosuppressive therapy is beneficial. We report a patient with EPO-induced PRCA treated with a regimen initially designed for antifactor VIII antibo
Digital photography and computerisation in orthopaedics
Hybridization between the peat mosses, Sphagnum capillifolium and S. quinquefarium (Sphagnaceae, Bryophyta) as inferred by morphological characters and isozyme markers
Isozyme markers and morphological characters were studied in four populations of Sphagnum capillifolium and S. quinquefarium. Recombinant plants were found in three populations, where the two species occur sympatrically. All recombinants possessed different haplotypes and combinations of morphological characters, which show that they are results of independent hybridization events. Strongly male-b

Stochastic description of traffic flow
We propose a traffic model based on microscopic stochastic dynamics. We built a Markov chain equipped with an Arrhenius interaction law. The resulting stochastic process is comprised of both spin-flip and spin-exchange dynamics which models vehicles exiting, entering and interacting in a two-dimensional lattice environment corresponding to a multi-lane highway. The process is further equipped with
What causes till thickness to change over distance? Answers from Myrdalsjokull, Iceland
Many explanations have been provided for variations of the spatial distribution and thickness of till sheets. This paper gives new insight into the architecture of a stratigraphically distinct till sheet as a function of the type of substratum and preadvance topography at a scale of similar to 10 km. This emphasises the sensitivity of the subglacial system to changes in the basal drainage conditio
The first independent chronology for Middle and Late Weichselian sediments from southern Sweden and the Island of Bornholm
Conventional Optically Stimulated Luminescence (OSL) dating using the equivalent dose distributions of 8 mm aliquots have been extended to key stratigraphical sites in southernmost Sweden and the island of Bornholm. The objective has been to bridge the lack of an independent chronology, which might catalyze a new understanding of the ice flow patterns related to the initiation of the Last Glacial
The social and environmental costs associated with water management practices in state environmental protection projects in Xinjiang, China
Since the late 1970s the central government of China has initiated several ecological environmental protection projects. The most significant of these has been the tui geng huan lin (returning cultivated land to forest and pasture) project in operation since the late 1990s. China's northwest region is characterized by lack of water resources, yet such resources are of vital importance. There is sc
Targeting hepatocytes from liver tissue by laser capture microdissection and proteomics expression profiling.
A tissue proteomics process is presented where hepatocyte cell isolation in combination with two-dimensional (2-D) gel electrophoresis and mass spectrometric identification were used to annotate the liver proteome. Laser microdissection of 8 m liver tissue sections was performed and protein expression profiling was compared using a variety of quantities of input cells, and gel separation condition
The parent between the child and the professional--some ethical implications
In this paper ethical implications of parental participation in paediatric care are discussed. The paper is based on interviews with 20 parents, whose children were admitted and operated on at a paediatric surgery department in Sweden. In one part of the interview the parent was invited to speak about situations experienced as problematic during the hospitalization. Three different types of situat
Preliminary study of D-dimer as a possible marker of acute bowel ischaemia
BACKGROUND: Occlusion of the superior mesenteric artery (SMA) demands prompt recognition and diagnosis. No accurate diagnostic method is available. The aim of this study was to determine whether the fibrinolytic marker D-dimer is a useful early marker of acute bowel ischaemia. METHODS: Fourteen patients suspected of having acute bowel ischaemia were analysed for an increase in plasma D-dimer level
Dinuclear complexes contributing to softness of metal acceptors
Since emf measurements with amalgam electrodes have been used, in most studies of the stabilities of complexes between soft metal acceptors and halide ions a series of investigations of the kinetics of electrode reactions were accomplished with halide systems of metal ions in the Groups 11 and 12 in aqueous and/or DMSO solutions. The aim was to establish which complexes contribute to the exchange
Spatial and spectral properties of the high-order harmonic emission in argon for seeding applications
We characterize and control the harmonic emission in the spectral and spatial domains in order to define in which conditions the harmonic radiation can be a high-quality seed for soft x-ray and x-ray free-electron lasers. The length of the gas cell, where harmonics are generated, was optimized and the energy per pulse was determined in absolute value with a calibrated x-ray photodiode. The beam sp
Epileptogenesis induced by rapidly recurring seizures in genetically fast- but not slow-kindling rats
A brief period of rapidly recurring hippocampal seizures can lead to the progressive development of a permanent increase of seizure susceptibility over several weeks, so-called 'delayed kindling'. We have analyzed seizure parameters critical for the induction of delayed kindling in two strains of rats characterized by fast and slow rates of traditional kindling, respectively. Forty seizures were p
Immigration and the incidence of Graves' thyrotoxicosis, thyrotoxic multinodular goiter and solitary toxic adenoma
Objective: Environmental and genetic factors influence thyrotoxicosis, but how population migration affects the disease panorama is not known. fit an urban area in southern Sweden, during the years 1990 until 2003, the population increased from 232 000 to 267 000. In parallel, the proportion of inhabitants born outside Sweden increased. The aim was to investigate whether the incidence of Graves' t
