Integration of Molecular Biology and Morphology in Effusions with Focus on in situ Detection of Telomerase and its Components
Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o
Modulation of postendocytic sorting of G-protein coupled receptors
Recycling of the mu opioid receptor to the plasma membrane after endocytosis promotes rapid resensitization of signal transduction, whereas targeting of the delta opioid receptor (DOR) to lysosomes causes proteolytic down-regulation. We identified a protein that binds preferentially to the cytoplasmic tail of the DOR as a candidate heterotrimeric GTP-binding protein (G protein)-coupled receptor-as
Orthosis as prognostic instrument in lumbar fusion. No predictive value in 50 cases followed prospectively
To evaluate pain relief in a lumbar orthosis as a predictor for good clinical results after solid fusion, all patients scheduled for such a surgical procedure were preoperatively encouraged to use an orthosis, soft or rigid, for 3 weeks. Grade of back pain relief as a percent using the orthosis was assessed by the patients and was registered before surgery. After surgery, at 1-year follow-up, pati
Self-renewal of multipotent long-term repopulating hematopoietic stem cells is negatively regulated by Fas and tumor necrosis factor receptor activation
Multipotent self-renewing hematopoietic stem cells (HSCs) are responsible for reconstitution of all blood cell lineages. Whereas growth stimulatory cytokines have been demonstrated to promote HSC self-renewal, the potential role of negative regulators remains elusive. Receptors for tumor necrosis factor (TNF) and Fas ligand have been implicated as regulators of steady-state hematopoiesis, and if o
Identification of brain tumours in rats using laser-induced fluorescence and haematoporphyrin derivative
Laser-induced fluorescence has been used for the identification of brain tumours in rats, which have been previously given tumour-seeking haematoporphyrin derivative. A pulsed nitrogen laser (λ=337 nm) was used in conjunction with an optical multichannel analyzer. For both inoculated RG-2 and TCVC rat-brain-tumour models, the blue autofluorescence was strongly reduced in the tumour compared with
Control Structure Design in Process Control Systems
Immunodominant epitopes of alpha3(IV)NC1 induce autoimmune glomerulonephritis in rats.
MR imaging in recurrent pain after back surgery. A comparative study using standard and high doses of gadolinium contrast agents
PURPOSE: To compare the diagnostic results following injection of (a) a high dose (0.3 mmol/kg b.w.) of gadodiamide injection and (b) the standard dose (0.1 mmol/kg b.w.) of Gd-DTPA, in patients with recurrent symptoms after surgery for lumbar disc herniation. MATERIAL AND METHODS: Twenty patients with recurrent or sustained symptoms after surgery for lumbar disc herniations were examined. MR imag

Oligosaccharide mapping of proteoglycan-bound and xyloside-initiated dermatan sulfate from fibroblasts
The copolymeric structure of dermatan sulfate chains synthesized by skin fibroblasts has been examined. Chains initiated onto exogeneous p-nitrophenyl-beta-D-xylopyranoside or attached to protein in a large proteoglycan, PG-L, and two small proteoglycans, PG-S1 and PG-S2, have been compared by using high resolution electrophoresis and gel chromatography of oligosaccharides generated by specific en
The European Frontier : Clashes and Compromises in the Middle Ages
During the Middle Ages the concepts of `them and us' became concrete in the shape of fiercely defended frontiers, some of which were physical, geographic and political, while others were more ideological. This volume, the proceedings of an international symposium held at Lund University in 2000, presents twenty-four papers which examine the archaeological evidence for frontiers across Europe. Divi

A comparison of chironomid biostratigraphy from Lake Vuolep Njakajaure with vegetation, lake-level, and climate changes in Abisko National Park, Sweden
Chironomid remains from the sediment of Lake Vuolep Njakajaure reflect limnological conditions resulting from changing climate and vegetation throughout the Holocene, but do not strictly follow accepted climate trends or the vegetation history based on regional pollen and macrofossil analyses. Chironomid community changes appear to be influenced by organic nutrient input from the surrounding catch
Relaxation kinetics of an L-3 (sponge) phase
The kinetic response of an L-3 (sponge) phase formed in the C12E5-n-decane-brine system is studied using the Joule-heating temperature jump (JHTJ) technique. The equilibrium state of the spongelike membrane is instantaneously perturbed, and the kinetic response is monitored using a multi-angle light scattering setup. These measurements yield a time-dependent scattering intensity as a function of t
Demonstration of sequence variations in the promoter region of the human cystatin C gene
Four point mutations in the promoter region of the human cystatin C gene have been detected by direct sequencing of polymerase chain reaction (PCR) amplified DNA. The four base changes are all localized within a short segment of 85 base pairs. Three cystatin C gene alleles could be defined with respect to these promoter mutations; one with the sequence previously published, one carrying three of t
LIFE SATISFACTION AND FEELING HINDERED BY HEALTH PROBLEMS AT 60 YEARS AND ABOVE
Popular Abstract in Swedish Idag finns det flera studier där livstillfredsställelse bland äldre har undersökts. Studierna är dels genomförda i varierande kontext och dels innehåller de varierande faktorer som hälsa, funktionell förmåga, självkänsla, sociala kontakter och finansiell situation. Därmed är det inte självklart att det finns gemensamma eller specifika faktorer, vilka är förknippade med The aim of this thesis was to investigate how older people's capacity to perform activities of daily living (ADL), health, social and financial resources, and self-esteem can be related to their life satisfaction. The aim was also to investigate how people feel hindered by health problems in relation to their ADL capacity, health problems, social and financial resources, self-esteem, sense of cohe
Search for new physics in e +/- q contact interactions at HERA
Deep-inelastic e(+/-) p scattering at high squared momentum transfer Q(2) up to 30 000 GeV2 is used to search for eq contact interactions associated to scales far beyond the HERA centre of mass energy. The neutral current cross section measurements dsigma / dQ(2), corresponding to integrated luminosities of 16.4 pb(-1) of e(-) p data and 100.8 pb(-1) of e(+) p data, are well described by the Stand
Water flow through porous materials. P. 3, Applications of the relative suction model
A 3-dimensional absorbed dose calculation method based on quantitative SPECT for radionuclide therapy: evaluation for (131)I using monte carlo simulation.
A general method is presented for patient-specific 3-dimensional absorbed dose calculations based on quantitative SPECT activity measurements. METHODS: The computational scheme includes a method for registration of the CT image to the SPECT image and position-dependent compensation for attenuation, scatter, and collimator detector response performed as part of an iterative reconstruction method.
