Persistent organochlorine pollutants (POPs) are suspected to interfere with hormone activity and the normal homeostasis of spermatogenesis. We investigated the relationships between sperm DNA fragmentation, apoptotic markers identified on ejaculated spermatozoa and POP levels in the blood of 652 adult males (200 Inuits from Greenland, 166 Swedish, 134 Polish and 152 Ukrainian). Serum levels of 2,
Human fibroblast and leukocyte interferons were found to suppress lymphocyte mitogenesis induced by optimal doses of phytohemagglutinin and concanavalin A. In certain situations (low doses of mitogen and/or low doses of interferon), however, interferon significantly enhanced mitogenesis. In experiments using varying concentrations of interferon, dose-response curves with different slopes were obta
Popular Abstract in Swedish I studier rörande de yngsta barnen saknas ofta genusperspektiv. Ett syfte med studien var därför att undersöka interaktionen mellan barnen (1-3 år gamla) och förskolepersonalen på småbarnsavdelningarna vid tre förskolor i ett genus- och kontextuellt perspektiv. Ett annat syfte var att undersöka pedagogernas föreställningar om barn och genus. Ett tredje syfte var att disIn studies concerning the youngest children, the toddlers, the gender perspective is often missing. One aim of the study was, therefore, to investigate the interaction between children and preschool teachers in day care centres in a gender and a contextual perspective. Another aim was to investigate the inner representations of the preschool teachers concerning children and gender. A third aim was
Objectives To explore case ascertainment, hospitalization, characteristics of both hospitalized and non-hospitalized patients in a population-based group of stroke patients. Materials and methods One-year screening in Lund-Orup district for first-ever strokes using multiple prospective and retrospective methods. Results A total of 456 patients with first-ever stroke (n = 412 prospective screening
The coordination environment of uranyl in water has been studied using a combined quantum mechanical and molecular dynamics approach. Multiconfigurational wave function calculations have been performed to generate pair potentials between uranyl and water. The quantum chemically determined energies have been used to fit parameters in a polarizable force field with an added charge transfer term. Mol
AimsTo examine determinants for glycaemic control in primary care patients with Type 2 diabetes. MethodsIn a community-based surveillance of primary care patients with Type 2 diabetes, 190 men and 186 women were consecutively identified and examined for cardiovascular risk factors. Insulin resistance and beta-cell function were estimated using homeostasis model assessment (HOMA). Good glycaemic c
Background: Funding organisations and research ethics committees (RECs) should play a part in strengthening attention to gender equality in clinical research. In the research policy of European Union (EU), funding measures have been taken to realise this, but such measures are lacking in the EU policy regarding RECs. Objective: To explore how RECs in Austria, Germany, Ireland, The Netherlands and
Currently, a single ion hit facility, for irradiation of single cells with single, light MeV ions is under development at the Lund Nuclear Microprobe. In this paper, a novel approach to the ion detection issue is presented. A silicon detector, a type utilized at other facilities for post-cell ion detection, has been investigated as a possible option for pre-cell hit detection. If proven successful
Bygg rätt från början är ett centralt motto om man vill bygga ett sunt hus. Fuktdimensionering är en hjälp för att lyckas med detta. Fukt orsakar ofta dålig innemiljö och kostnaden för att åtgärda fuktskador uppgår till miljardbelopp årligen. Genom att använda den kunskap som finns skulle de vanligaste fuktproblemen kunna undvikas. Kunskapen finns dokumenterad bl a i serien Fuktsäkerhet i byggnade
Objectives. To investigate the total dispersion of ventricular repolarization of the epi- and endocardium. Design. Monophasic action potentials (MAP) were recorded from 211 +/- 54 (151-353) left and right ventricular epi- and endocardial sites during atrial pacing in 10 pigs using the CARTO system. The activation time (AT), MAP duration (MAPd) and end of repolarization time (EOR) were measured. Re
This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon. A method
The neuropeptide gastrin releasing peptide (GRP) stimulates insulin secretion and induces oscillations of the cytoplasmic Ca(2+) concentration ([Ca(2+)](cyt)) in clonal insulinoma cells. It is not known whether GRP affects [Ca(2+)](cyt) in normal beta cells. We investigated, in single, normal, mouse islet beta cells, the effects of GRP on [Ca(2+)](cyt), by dual wavelength spectrophotofluorometry.
The paper discusses dynamic real-time scheduling in the context ofmodel predictive control (MPC). Dynamic scheduling in this settingis motivated by the highly varying execution times associated withMPC controllers. Premature termination of the optimization algorithmis exploited to trade off prolonged computations versuscomputational delay. A feedback scheduling strategy for multiple MPCcontrollers
Groups of male mice were exposed via inhalation to methylene chloride, perchloroethylene, toluene, trichloroethylene or 1,1,1-trichloroethane. The exposures were started at 2300 h. Generation of vapor was stopped after 1 h. Motor activity of the animals during the exposures was measured with a Doppler radar. Several concentrations of each solvent were tested. Concentrations could be found for all
Popular Abstract in Swedish Prostatacancer är den bland män vanligast förekommande cancerformen i Sverige. Under 2003 diagnostiserades 9882 nya fall. Sjukdomen drabbar framför allt äldre individer; många män är 70 år gamla eller äldre när de får diagnosen. Sjukdomsförloppet kan vara mycket varierande. Hos många är tumörtillväxten långsam, men sjukdomen kan också utvecklas snabbt. Många patienter lConcentrations of prostate-specific antigen (PSA) and human kallikrein 2 (hK2) were investigated in blood samples that had been obtained from men who were diagnosed with prostate cancer (PCa) decades later. The studies were based on a cohort comprising 22,444 men who, in 1974?1986, were early middle aged and represented a non-PCa-screened population. The results clearly demonstrate a very strong c
