Theoretical investigations of hyperfine quenching of the two metastable levels 1s(2)2s2p P-3(0) and P-3(2) have been performed along the Be-like isoelectronic sequence for ions between Z=6-22. It is shown that the lifetime of the latter level is sensitive to hyperfine quenching in the beginning of the isoelectronic sequence, but the sensitivity decreases towards the high-Z end. It is also shown th
Allogeneic haematopoietic stem cell transplantation remains the only curative treatment of myelofibrosis with myeloid metaplasia (MMM). Previous reports have indicated significant treatment-related mortality (TRM) for patients transplanted after myeloablative conditioning but superior survival has been reported after reduced-intensity conditioning (RIC). We report the results of a survey of all al
The use of commercial proteases, bromelain and Protex 30L for oil extraction/recovery of polyunsaturated fatty acids (PUFA) from Nile perch and salmon heads was evaluated. Four phases were obtained after hydrolysis, oily phase, emulsion, aqueous phase and sludge. An increase in water content during the hydrolysis resulted in a decrease in oil yield. Maximum oil yield was obtained when hydrolysis w
The ZZ production cross section in proton-proton collisions at 13 TeV center-of-mass energy is measured using 3.2 fb-1 of data recorded with the ATLAS detector at the Large Hadron Collider. The considered Z boson candidates decay to an electron or muon pair of mass 66-116 GeV. The cross section is measured in a fiducial phase space reflecting the detector acceptance. It is also extrapolated to a t
Popular Abstract in Swedish Vi är under ständig attack från mikroorganismer som vill leva på oss och i oss. Vissa av dessa är vanligtvis nyttiga medan andra är sjukdomsframkallande. Kroppens försvar mot invaderande organismer består av många delar. Ytterst sitter huden som en mekanisk barriär, vi har slem och epitelceller i luftvägar och magtarmkanal samt skyddande ämnen i exempelvis tårvätska. I Transplantation antigens encoded in the major histocompatibility complex (MHC) bind peptides and present them to T cells. We showed that mouse T cells expressing transgenic human CD8 can recognise human MHC class I. Expression on mature T cells is sufficient for activation in a mixed lymphocyte culture but expression both on thymocytes and mature T cells is necessary for peptide specific MHC restr
Popular Abstract in Swedish Ben, brosk och mjukvävnad (utgörs av den tvärstrimmiga muskulaturen, fettväv och fibrös bindväv, men också av det perifera nervsystemet) är vävnader av mesenkymalt eller neuroektodermalt ursprung. De flesta tumörer som uppstår i dessa vävnader är godartade och blir därför ofta inte föremål för behandling, vilket gör det svårt att uppskatta incidensen i befolkningen. EnlBone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoin
Five Swedish patients with chronic hepatitis C were prospectively followed until hepatocellular carcinoma (HCC) developed. Hepatitis C virus (HCV) antibodies were analysed by a second generation anti-HCV ELISA and a recombinant immunoblot assay (RIBA-2) and viraemia by detection of serum HCV RNA by polymerase chain reaction. Four patients had post transfusion hepatitis and in one patient the sourc
Popular Abstract in Swedish Diffust storcelligt B-celllymfom (DLBCL) är den vanligaste aggressiva lymfomsjukdomen, och drabbar ca 450 personer årligen i Sverige. Med modern antracyklin-innehållande cytostatikabehandling är DLBCL en potentiellt botbar sjukdom. Av patienter med lokaliserad sjukdom botas 70 %, med spridd sjukdom ca 50 %. Bakgrunden till arbete 1 i denna avhandling var en rapport därDiffuse large B-cell lymphoma (DLBCL) is the most frequent lymphoma subtype. In Sweden 450 new cases are diagnosed annually. With modern anthracycline-containing chemotherapy DLBCL is potentially curable, with an estimated overall cure rate of approximately 50% for patients with advanced stage disease. Through molecular profiling of DLBCL the ?cell-of-origin concept? has been established: patients
Here we investigated whether microwaves (MWs) of Global System for Mobile Communication (GSM) induce changes in chromatin conformation in human lymphocytes. Effects of MWs were studied at different frequencies in the range of 895-915 MHz in experiments with lymphocytes from seven healthy persons. Exposure was performed in transverse electromagnetic transmission line cell (TEM-cell) using a GSM tes
Objective: To update estimates of cancer risk in SLE relative to the general population. Methods: A multisite international SLE cohort was linked with regional tumor registries. Standardized incidence ratios (SIRs) were calculated as the ratio of observed to expected cancers. Results: Across 30 centres, 16,409 patients were observed for 121,283 (average 7.4) person years. In total, 644 cancers occ
Incidence of differentiated thyroid carcinoma (DTC) varies considerably between ethnic groups, with particularly high incidence rates in Pacific Islanders. Here, we conducted a genome-wide association study (GWAS) involving 1,554 cases/1,973 controls of European ancestry and 301 cases/348 controls of Oceanian ancestry from the EPITHYR consortium. Our results confirmed the association with the know
Abstract in UndeterminedThe popularity of the Internet and marketers' increased investments in Internet advertising have raised some questions concerning a marketer's power to influence children and young people's consumption through new media technology. This article, based on a recent explorative study of 15-year-old Swedish teenagers, aims to discuss their exposure-potential, actual, and percei
A spectrophotometric assay for plasmin and plasminogen-derived activity in dairy products was optimised and extended to determine plasmin and plasminogen-derived activity in turbid samples of dairy products. The method was validated by assessing reproducibility, repeatability, level of detection and recovery of plasmin activity in different sample matrices. Plasmin activity in raw milk was not aff
In this study, two experiments were conducted to evaluate the impact of substrate concentrations on methane potential and degradation kinetics of substrate. The biochemical methane potential (BMP) tests in Experiment I were performed at a constant inoculum to substrate ratio (ISR), whereas, different ISRs were applied in Experiment II. Results obtained from Experiment I revealed that methane poten
De flesta makar och sambor bor tillsammans i en fastighet eller i en lägenhet som de vanligtvis betraktar som deras gemensamma bostad. Inte ovanligt är att fastigheten utgör en lantbruksfastighet eller att någon av parterna bedriver näringsverksamhet i bostaden. För makar och sambor finns i äktenskapsbalken respektive sambolagen ett par skydds¬regler som kan bli tillämpliga vid en separation mellaThe majority of married couples and co-habitants live together in rented or owned accommodation which they usually consider to be their joint property. It is not unusual that the property is an agricultural property or that one half of the couple use the property for business purposes. There are protective provisions in The Marriage Code and also in The Cohabitees Act which are relevant in case of
Creating Non-governmental Self-help groups (SHGs) has been a common thing in India since the early 1990’s. Studies show that the SHGs usually empower their members in different ways. The empirical material being used in this paper consists of one group discussion and twelve semi-structured interviews with members of five different SHGs being organized by a Non governmental organization (NGO) in Mu
ABSTRACT Background: Approximately 15 % of all couples in the Western countries experience infertility. Up to half of these cases are thought to solely or partly depend upon the male factor. In most cases male infertility is unexplained. During the last decade there has been a growing focus on sperm DNA damage as a cause of male infertility. Sperm chromatin structure assay (SCSA) is increasingly
