Mycobacterium tuberculosis complex strains cultured in Denmark have been analyzed by IS6110 restriction fragment length polymorphism (RFLP) on a routine basis from 1992 and onwards. Due to the influx of immigrants with tuberculosis, the number of strains harboring only one to five copies of IS6110 has increased steadily. Since the discriminatory power of IS6110 fingerprinting for such strains is p

Eight antibody-positive individuals were detected among 12,000 blood donations during the first year of screening blood donors for hepatitis C virus (HCV) antibodies in Iceland. All 8 were found to have a history of intravenous drug abuse. Six of these 8 individuals had previously donated blood to 27 patients who could be traced and examined for HCV infection. The great majority (23/27, 85%) of th

Enzymatic removal of blood group ABO antigens to develop universal red blood cells ( RBCs) was a pioneering vision originally proposed more than 25 years ago. Although the feasibility of this approach was demonstrated in clinical trials for group B RBCs, a major obstacle in translating this technology to clinical practice has been the lack of efficient glycosidase enzymes. Here we report two bacte

The results of Swanson and Avanta metacarpophalangeal joint arthroplasties in rheumatoid patients were compared in a prospective, randomized study of 30 patients (120 implants). At 2-year follow-up, grip strength was measured, hand function was assessed with the Sollerman test and the subjective outcome was determined with visual analogue scores. With both implants ulnar deviation and flexion defo

Some recent Swedish data on compartment fires are reviewed. Measured burning rates were as high as 7.7 A √ H kg/min where A is the opening area in m² and H is its height in m. A conventional power law is shown to relate the burning rate and the measured external flame length as well as does an empirical proportionality. The corrections to be allowed in both methods for the burning within the compa

Objectives. To evaluate the relationship between anti-neutrophil cytoplasmic antibody (ANCA) measured with two different methods and long-term clinical course in vasculitis. Design. Retrospective determination of ANCA with two different assays for detection of PR3-ANCA, conventional direct binding ELISA and capture ELISA using monoclonal antibodies against PR3. The 245 ANCA determinations were per

Popular Abstract in Swedish Hur förhåller sig ekonomisk tillväxt och fördelning till varandra när en ekonomi genomgår en strukturomvandlingsprocess? Denna klassiska frågeställning utgör det centrala problemet för denna avhandling. När Simon Kuznets i mitten av 1950-talet tog sig an samma fråga fann han med begränsade data att ekonomisk tillväxt förmodligen ökar inkomstklyftorna under en inledande What are the effects of growth on equality in a long-term perspective? What are the effects of different patterns of equality on subsequent growth? And why are these questions relevant for the understanding of economic development? These are the overriding questions posed in the dissertation. They are addressed in the context of long-term change from economic backwardness to modern economic growth

Apolipoprotein M (apoM) is a novel apolipoprotein present mostly in high-density lipoprotein (HDL) in human plasma. In the present study, we demonstrate that insulin, insulin-like growth factor I (IGF-I), and IGF-I potential peptide (IGF-IPP) significantly inhibits apoM expression, in a dose- and a time-dependent manner, in the human hepatoma cell line, HepG2 cells. Insulin-induced down-regulation

Abstracts of all master theses, made at the Division of Automatic Control, Lund Institute of Technology, are collected in this report. The theses, made from 1965 until July, 1, 1970, are ordered chronologically. The report is mainly written for other research institutes in the field of automatic control, industries, individual researchers as well as future candidates for master theses. The purpose

Phosphatidylethanol is formed by phospholipase D in animal cells exposed to ethanol. Previous reports have demonstrated that the degradation of phosphatidylethanol is slow, indicating that this lipid may be present in the cells after ethanol itself has disappeared. Accumulation of an abnormal alcohol metabolite may influence cellular functions. In the present study, cultivation of NG108-15 neurobl

Objective: The aim of this systematic literature review was to evaluate associations between different malocclusions, orthodontic treatment, and signs and symptoms of temporomandibular disorders (TMD). Materials and Methods: This review was part of a project at the Swedish Council on Technology Assessment in Health Care focusing on malocclusion and orthodontic treatment from a health perspective.

Aims To test the association between the immunoreceptor PD-1 (PDCD1) gene and Type 1 diabetes mellitus (T1DM). This gene has been reported to be associated with other autoimmune diseases such as systemic lupus erythematosus (SLE) as well as T1DM. Methods Genotyping of single nucleotide polymorphisms (SNPs) in the PDCD1 gene was performed using polymerase chain reaction-restriction fragment length

The evolution of the order Cetacea (whales, dolphins, porpoises) has, for a long time, attracted the attention of evolutionary biologists. Here we examine cetacean phylogenetic relationships on the basis of analyses of complete mitochondrial genomes that represent all extant cetacean families. The results suggest that the ancestors of recent cetaceans had an explosive evolutionary radiation 30-35

The insulin-secreting pancreatic beta cell is electrically excitable and changes in the membrane potential play an important role in coupling the metabolism of glucose (and other nutrient secretagogues) to the discharge of the insulin-containing granule. The application of the patch-clamp technique, which permits the recordings of the minute currents associated with the opening of individual ion c

An eight-band k.p theory that does not suffer from the spurious solution problem is demonstrated. It is applied to studying the electronic properties of InP and InAs free-standing nanowires. Band gaps and effective masses are reported as a function of size, shape, and orientation of the nanowires. We compare our results with experimental work and with other calculations.

Fluorescence spectra from different organs in rats and mice have been recorded to explore the potential of non-intrusive tissue diagnostics. The fluorescence was induced by a nitrogen laser that emitted at a wavelength of 337 nm. Optical multichannel techniques were used for the detection. Spectra are given from 19 different sites in Wistar/Furth rats, including an inoculated malignant tumour. The
