Matrilin-2 is a component of extracellular filamentous networks. To study the interactions by which it can be integrated into such assemblies, full-length and truncated forms of matrilin-2 were recombinantly expressed in HEK-293 cells and purified from conditioned medium. The recombinant proteins, when used in interaction assays, showed affinity to matrilin-2 itself, but also to other collagenous
The four IgG subclasses of the rat, IgGl, IgG2a, IgG2b and IgG2c, were purified from normal serum by a combination of protein A-affinity chromatography and DEAE-cellulose chromatography. Purified, radiolabelled preparations of IgG were tested for binding to Gram-positive bacteria representing five different Fc-receptor (FcR) types. Distinct rat subclass-specific Fc-binding was noted to bacterial s
Objective: Oligoclonal bands (OBs) in electrophoresis of cerebrospinal fluid (CSF) are present in multiple sclerosis and here is investigated whether these also occur in experimental autoimmune encephalomyelitis (EAE). Material and methods: Experimental autoimmune encephalomyelitis was induced in 42 DA rats after immunization with rat spinal chord homogenate and the occurrence of OBs were detecte
Iterative receiver algorithms for multi-user detection and decoding are a solution for mitigating multiple-access interference in multiple access communication systems. After several iterations they outperform noniterative schemes, while maintaining modest complexity. In this paper, we present an iterative receiver for multiple-antenna systems in frequency selective fading. Channel knowledge is no
Plesiomonas shigelloides was isolated as the sole pathogen from gallbladder bile and wall in a 58-year-old woman with acute cholecystitis. The patient developed an unusual postoperative complication characterized by culture-negative discharge from the wound in combination with extensive abdominal cellulitis and afebrility. Agglutinating antibodies to P. shigelloides were demonstrated in the serum
Objectives The aim was to survey the rate and cause of cancellations of planned cardiac operations at a Swedish clinic during 1999, and to study how the patients were affected. Design Questionnaires were distributed to 74 patients who had their operations cancelled. Their mood after discharge was measured with The Hospital Anxiety and Depression scale. Ninety-three patients, who were operated on w
Ultra-thin graphite overlayers prepared by heating SiC crystals can give highly resolved valence band photoemission spectra. This is exploited to monitor K deposition induced energy shifts of graphite valence band states. States near the corners of the Brillouin zone, responsible for the semimetal character of graphite, are observed to show shifts that are nearly equal to the shifts of the uppermo
Neuroblastoma is a childhood tumor derived from the sympathetic nervous system (SNS). It is believed that the tumors arise from cells halted in their differentiation and due to their immature phenotype; they express proteins normally only detected during embryogenesis. One such protein is Hash-1, which is required for formation of the SNS. Hash-1 is a component of the Notch signaling cascade, whic
With the increasing capacity in today's hardware system design enabled by technology scaling, image processing algorithms with substantially more complexity can be implemented in a single chip with real-time performance. Combined with the demand for low power consumption or larger resolution seen in many applications such as mobile devices and HDTV, new design methodologies and hardware architectu
During the last years there has been reported considerable and rapid contamination on newly built rendered façades in Sweden due to biological growth. The problem is believed to occur mostly on façades of render applied on thermal insulation, but apart from this it is difficult to find clear relationships indication which façades might be infected. The aim of this project is to explain why certain
We study the simulation of stochastic processes defined as stochastic integrals with respect to type G Levy processes for the case where it is not possible to simulate the type G process exactly. The type G Levy process as well as the stochastic integral can on compact intervals be represented as an infinite series. In a practical simulation we must truncate this representation. We examine the app
Datortomografi av kolon (DT-kolografi) är en ny tillämpning av datortomografi, som gör det möjligt att med hög diagnostisk säkerhet upptäcka tumörer och polyper större än 10 mm. Metoden medför mindre obehag och smärta än koloskopi och kolonröntgen. Behovet av tarmrengöring är dock detsamma. DT-kolografi kan, som initial undersökning vid misstanke om maligna förändringar eller kolonpolyper, komma a
