OBJECTIVE: To investigate patients with cystic enhancing lesions on CT and to determine whether thallium-201 (201Tl) SPECT adds to further preoperative information in differential diagnosis between gliomas and abscesses. METHODS: Twenty one patients with cystic ring enhancing CT findings were studied and uptake indices were compared with CT enhancement volumes, histopathology, and survival times.
Popular Abstract in Swedish Denna studie handlar om interpersonell kommunikation mellan barn och vuxna i särskolan. Specifikt inriktas den på att studera den kommunikation som sker när de kommunikationssätt som parterna använder är teckenspråk och tecken och samtidigt tal. I fokus är elever med hörselnedsättning och utvecklingsstörning, vilken är en liten, unik och outforskad elevgrupp, men också Pupils with impaired hearing and moderate to severe learning difficulties usually go to special schools for the severely learning disabled. Few studies have been conducted on the interpersonal communication among these pupils. The all-embracing aim of this study is to look closer into the communication that takes place during the school day between children and adults, in cases where Sign Language
An emerging concept in neurobiology is that the adult brain retains a capacity for plasticity and functional reorganization throughout the life span. Experimental data from electrophysiological, morphological and behavioral studies have documented experience dependent plasticity in the intact and injured adult brain. Neuroimaging clinical studies indicate altered post stroke functional activation
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
BACKGROUND: The aim of the study was to evaluate if physical functions usually associated with a younger population were of importance for an older population, and to construct an outcome measure for hip osteoarthritis with improved responsiveness compared to the Western Ontario McMaster osteoarthritis score (WOMAC LK 3.0). METHODS: A 40 item questionnaire (hip disability and osteoarthritis outcom
A method is presented for building solvers for classes of multivariate polynomial equations. The method is based on solving an analogous template problem over a finite field, and then using the elimination order established for this problem for the original class of problems. A strength of this method is that this permits pivoting in the elimination. Solvers for several minimal problems in
Popular Abstract in Swedish Helicobacter pylori är en av de vanligaste infektionerna hos människan. H. pylori framodlades för första gången 1983 av Robin Warren och Barry Marshall. Bakterien ger en kronisk inflammation i magslemhinnan. H. pylori orsakar magsår och möjligheten att behandla sjukdomen med antibiotika har inneburit en revolution inom sjukvården. Hos flertalet sker infektionen i barndoHelicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. Nested case-control studies were performed in the Malmö P
Popular Abstract in Swedish I takt med att analytiska dimensioneringsmetoder utvecklas ökar även behovet av att kunna bestämma mekaniska egenskaper hos materialen i överbyggnaden och terrassen. Utmattningssprickor orsakade av tung trafik, permanenta deformationer (spårbildning), termisk sprickbildning, ojämnheter, tjäle och reflektionssprickor är några av de dimensioneringskriterier som kan användThe advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement. The objective of this Ph.D. project is to eva
Popular Abstract in Swedish Syftet med avhandlingen är att presentera en sociologisk analys av en "religionsfrihetssituation". Den grupp som särskilt berörs i avhandlingen är den invandrarde muslimska minoriteten i Sverige, en grupp som har vuxit avsevärt under de senaste decennierna. Muslimerna har invandrat till ett samhälle som länge präglades av religiös enhet, men som idag har utvecklats tillThis dissertation deals with the religious liberty situation of the Muslim minority in Sweden. The Muslim minority has grown considerably in recent decades as a consequence of labour and refugee immigration of a large scale, which has caused a change in Swedish society from an etnically, culturally and religously homogeneous situation to one of a significant heterogeneity. Sweden's way from unity
In this pilot study a new device for respiratory stimulation with undulating oscillations and high frequency vibrations via an air mattress was tested as an additional therapy in 12 preterm infants with recurrent apnoeic episodes. The mean birthweight of the study population was 1760 g and gestational age 31.1 weeks. it was shown that an oscillating air mattress is an effective additional mode of
The mucosal lymphocyte integrin alpha E(CD103)beta 7 is thought to be important for intraepithelial lymphocyte (IEL) localization or function. We cloned the murine integrin gene encoding alpha E, localized it to chromosome 11, and generated integrin alpha E-deficient mice. In alpha E-/- mice, intestinal and vaginal IEL numbers were reduced, consistent with the known binding of alpha E beta 7 to E-
It is generally difficult to analytically derive models describing the echo attenuation in pulsed gradient spin-echo (PGSE) experiments for even he simplest porous systems that are commonly studied-especially when the gradient pulse (delta) is of finite length compared to the timescale of the diffusion measurement (Delta). Consequently, various levels of approximation are used to evaluate PGSE ex
Objectives Exposure to aluminium compounds, such as fluorides in gaseous and particulate form, places people who work in potrooms at risk for respiratory symptoms. Workers in potrooms, however, also are exposed to a number of other air contaminants. In this study, we present the first report of a dose-response relationship after exposure to potassium aluminium tetrafluoride (KAlF4) and the influen
Student speech production is an essential part of language learning in the foreign-language classroom. The students usually have few opportunities to use the language outside the classroom, which underscores the importance of making good use of the time spent in the classroom. Much research has shown that learner output is necessary, or at least facilitative, in language acquisition. This claim fo
