BACKGROUND AND PURPOSE—: Compared with ischemic stroke (IS), the association of atrial fibrillation (AF) with transient ischemic attack (TIA) is less well established. We aimed to assess the proportion of AF in patients with TIA, and these patients’ characteristics and secondary preventive treatment in comparison to patients with IS. METHODS—: Hospital-based data on TIA and IS events, registered f
OBJECTIVE: To determine moment arm lengths from seven knee muscles and the patellar tendon. The knee muscles were the biceps femoris, semitendinosus, semimembranosus, gracilis, sartorius, and the lateral and medial gastrocnemius muscles. DESIGN: The moment arms were calculated based on MRI measurements. BACKGROUND: Moment arm lengths of different muscles with respect to the joint centre of rotatio
Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column. DOC is a heterogeneous mixture of molecules, some of which are imported from the watershed (allochthonous DOC) and others that are produced by autotrophs within the system (autochthonous DOC). We examined the importance of autochthonous versus allochthonous DOC in supporting the growth of p
Vertebral deformities are a common consequence of osteoporosis and are known to decrease quality of life. The Qualeffo-41 is a quality-of-life questionnaire especially developed for measuring quality of life in patients with vertebral deformities. It consists of 41 questions arranged in five domains: pain, physical function, social function, general health perception, and mental function. The obje
Popular Abstract in Swedish För att vi människor ska kunna upprätthålla balansen och utföra rörelser behöver vi ett komplext styrsystem som kontinuerligt kontrollerar och samordnar kroppens rörelser. Detta styrsystem, som kallas postural kontroll, får sin information från synen, balanssinnet (vestibularisorganen), led-muskelsinnet (proprioception) och receptorer i huden (mekanoreceptorer). Om någoThe ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. This emphasizes the importance of rapid and accurate adaptation processes that can optimize
Popular Abstract in Swedish Denna avhandling behandlar den process där man beräknar undervattensströmmar från ljud som reflekteras från en utsänd ljudpuls, precis som när en fladdermus bedömer omgivningen genom att lyssna på ekot. En ton skickas ut under en kort tid, och det Dopplerskift som uppkommer från rörliga föremål i vattnet kan sedan omsättas till vattenhastiget eller ström. Föremål som röThis thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. The traditional mathematical model for this Doppler process is based on the assumption that the backscattering time signal is Gaussi
The thesis concerns risk and safety in manufacturing companies in a developing country. Risk and safety is viewed as integral to the social relations between management and labour. The Malaysian case presents a historical conjuncture of this conflict theme, which is very different from that of its Western genesis. On this basis, the primary objective of the thesis is defined as an effort to escape
Incidence of cancer of unknown primary (CUP) varies globally, and environmental factors are suspected to be related to its development. Immigrant studies offer insights into disease etiology, but no studies have been published on CUP. We investigated CUP risk in immigrants to Sweden to search for etiological clues. The nationwide Swedish Family Cancer Database was used to calculate standardized in
This review aimed at covering cancer risk trends by site and histology in first-generation and second-generation immigrants in Sweden compared with natives. In addition, we reviewed data on cancer survival in immigrants to explore factors explaining cancer survival in the entire population. The Swedish Family-Cancer Database was used to calculate standardized incidence ratios and hazard ratios (HR
The effect of the anionic surfactant SDS (sodium dodecyl sulfate) on the adsorption behaviors of cationic hydroxyethyl celluloses (Polymer JR-125, JR-400, and JR-30M) and hydrophobically modified cationic cellulose (Quatrisoft LM-200) at silica surfaces in the presence of a 10 mM NaCl solution has been investigated by null ellipsometry. The adsorbed amount of LM-200 is found to be considerably lar
Microzarkodina is a genus of mainly Middle Ordovician conodonts that has its centre of distribution in Baltoscandia, and much less commonly occurs in southern China, Australia, Argentina and Laurentia. In Baltica a series of species, Microzarkodina russica n. sp., M. flabellum, M. parva, M. Bella, M. Hagetiana and M. ozarkodella, established themselves successfully. The succession of species range
Here, we describe the preparation, structure, and properties of cryogel sponges, which represent a new type of macroporous biomaterial for tissue engineering. Cryogels were produced through freeze-thawing techniques, either from agarose alone or from agarose with grafted gelatin. The aim of this study was to evaluate agarose cryogel sponges as scaffolds for Culturing both isolated pancreatic islet
The effect of an intestinal microflora consisting of selected microbial species on myoelectric activity of small intestine was studied using germ-free rat models, with recording before and after specific intestinal colonization, in the unanesthetized state. Intestinal transit, neuropeptides in blood (RIA), and neuromessengers in the intestinal wall were determined. Clostridium tabificum vp 04 prom
Background. The Lundby Study is a longitudinal cohort study on a geographically defined population consisting of 3563 subjects. Information about episodes of different disorders was collected during field investigations in 1947, 1957, 1972 and in 1997. Interviews were carried out about current health and past episodes since the last investigation; for all subjects information was also collected fr
Here we present data to demonstrate how partitioning of a hydrophilic enzyme can be directed to the hydrophobic detergent-enriched phase of an aqueous two-phase system by addition of short stretches of amino acid residues to the protein molecule. The target enzyme was the industrially important endoglucanase I, EGI (endo-1,4-beta-D-glucan-4-glucanohydrolase, EC 3.2.1.4, Cel7B) of Trichoderma reese
BACKGROUND: Contact allergy to textile dyes is not uncommon. The allergy is detected by patch testing patients with commercial patch test preparations. OBJECTIVE: To investigate 8 disperse dyes (DDs) used for patch testing in the departments in Malmö and in Leuven and to compare them with test preparations used at various dermatology departments. Materials/Methods: The investigated DDs were Disper
