BACKGROUND AND PURPOSE: Although the incidence of and mortality from myocardial infarction (MI) have declined in most industrialized countries, incidence studies of stroke have shown less consistent trends. This study examines time trends in the incidence of stroke and case fatality rates in relation to socioeconomic circumstances and history of MI.METHODS: Stroke incidence in the city of Malmö, S
High-spin states of T-z = 1 nuclei were studied with the reactions Ni-58(Si-28,3 alpha)Kr-74,Ni-58(Si-28,2 alpha)Sr-78, and Ni-58(Si-28,2p2n)Zr-82 at 130 MeV beam energy. The Gammasphere array in conjunction with the 4 pi charged-particle detector array Microball was used to detect gamma rays in coincidence with evaporated light charged particles. The known pi = +, alpha = 0 yrast bands were exten
A measurement of charm and beauty dijet photoproduction cross sections at the ep collider HERA is presented. Events are selected with two or more jets of transverse momentum Pt > 11(8) GeV in the central range of pseudo-rapidity -0.9
DNA ploidy and S-phase fraction (SPF) were determined by flow cytometry on paraffin-embedded tumor material from 243 patients treated during 1980-1985. Patients with well differentiated and moderately differentiated tumors without solid areas (n = 351) formed a low-risk group (corrected 5-year survival 90%). Twenty-four patients, dead of disease within 5 years, were compared with 52 survivors. The
Cross-linking of polyvinylalcohol (PVA) by boronate-containing copolymer of N,N-dimethylacrylamide (DMAA, 1) was studied and compared to cross-linking of PVA by borate buffers in weakly alkaline solutions. The copolymer of M-w = 19,000 g mor(-1) containing 9 mol% N-acryloyl-m-aminophenylboronic acid (NAAPBA, 2) was prepared by free radical polymerization of the monomers, exhibiting copolymerizatio
AIMS: To test a stress-disease hypothesis by investigating the influence of social network and social support factors on the course over time of the CD4 lymphocytes in an HIV-positive population of gay men. METHODS: The study is a prospective cohort study of a representative population of HIV-positive gay men, undertaken at the Department of Infectious Diseases, Malmö University Hospital. This is
In chlorophyll biosynthesis, insertion of Mg2+ into protoporphyrin IX is catalysed in an ATP-dependent reaction by a three-subunit (BchI, BchD and BchH) enzyme magnesium chelatase. In this work we present the three-dimensional structure of the ATP-binding subunit BchI. The structure has been solved by the multiple wavelength anomalous dispersion method and refined at 2.1 A resolution to the crysta
Inclusive jet production is studied in neutral current deep-inelastic positron-proton scattering at large four momentum transfer squared Q(2) > 150 GeV2 with the H1 detector at HERA. Single and double differential inclusive jet cross sections are measured as a function of Q(2) and of the transverse energy E-T of the jets in the Breit frame. The measurements are found to be well described by calcul
A review of the literature on the effects of adding electrolytes to ionic as well as nonionic contrast media (CM) in the isolated heart model reveals that both ionic and nonionic CM favor from such addtion, if the added electrolytes are balanced with respect to each other. By enriching nonionic monomeric as well as dimeric CM with such a balanced electrolyte solution, the risk of ventricular fibri
The human genome harbors numerous distinct families of so-called human endogenous retroviruses (HERV) which are remnants of exogenous retroviruses that entered the germ line millions of years ago. We describe here the hitherto little-characterized betaretrovirus HERV-K(HML-5) family (named HERVK22 in Repbase) in greater detail. Out of 139 proviruses, only a few loci represent full-length proviruse
The movements of the basis of maxilla 2 in Palaemon adspersus were examined using macro-video recordings, and the morphology of its setae was examined using both scanning and transmission electron microscopy. The basis of maxilla 2 performs stereotypical movements in the latero-medial plane and gently touches the food with a frequency of 3-5 Hz. The medial rim of the basis of maxilla 2 carries thr
Rearrangements of chromosome bands 12q13-15 are frequent in various benign mesenchymal and epithelial tumors, and the gene HMGA2 seems to be the most common target within this chromosome region. In the majority of cases, the rearrangements result in a fusion of the first three exons of HMGA2 with different translocation partners. Despite the large number of HMGA2 mutations that have been reported,
Popular Abstract in Swedish Avhandlingen har fokus på lungornas mekaniska egenskaper hos friska och vid akut lungskada och på metodutveckling för studier av lungmekanik. Kunskap om lungmekanik är av intresse inom intensivvården för att skräddarsy respirator-behandling och i lunglaboratoriet för diagnostik och utvärdering av patienter med olika typer av lungsjukdom. Vid respiratorbehandling kan föKnowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure
