Popular Abstract in Swedish Kvinnor känner till att det är riskabelt att röka när de blir gravida. Trots detta så slutar bara omkring hälften i Sverige och var tredje kvinna i många andra länder att röka när de blir gravida. Syftet i den här avhandlingen har varit att studera varför det är så svårt för gravida kvinnor att sluta röka. Problemområdet har studerats med olika utgångspunkter; gravida kThe aim of this thesis has been to increase understanding on the process of smoking cessation during pregnancy from the perspective of learning. The smoking pattern before and after pregnancy related to health, Sense of Coherence (SOC) and social issues was studied among all pregnant women in south-east Skåne during the period March 1994 to August 1995. They were asked to fill in a questionnaire d

Popular Abstract in Swedish Miljontals fåglar lämnar Sverige varje höst för att övervintra på sydligare breddgrader och återvänder nästkommande vår för att föda upp sina ungar på de enorma mängder insekter som finns här tack vare det tempererade klimatet. Småfåglar genomför sin flytt etappvis genom att flyga ett antal dagar eller nätter i sträck, beroende på om fågeln är en dag- eller nattsträckar

Popular Abstract in Swedish Så gott som alla metaller reagerar vid normala omständigheter med syret i luften och oxideras, vilket förändrar materialets egenskaper. T.ex. rostar järn efter hand, något som alla bilägare är bittert medvetna om. Oxider behöver dock inte vara negativa, utan kan även fungera som barriärer mot fortsatt korrosion, isolerande skikt i mikroelektronikkomponenter m.m. FöljaktThe oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scannin

Popular Abstract in Swedish Vad har jag gjort de senaste åren? Och varför? Det är det många som har undrat. Så stundtals även jag. Vad jag skriver nedan syftar inte till att förklara detta, utan är bara ämnat som en kort introduktion. Jag har de senaste åren jobbat med gener och proteiner från både växter och bakterier. Både gener och proteiner är väldigt små saker, men även den minsta lilla sak This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. The focus has been to establish where the metal and the porphyrin binds to the enzyme, and how they are pu

This thesis has evaluated the immunological- and epidemiological aspects of human papillomavirus transmission dynamics and its effect on circumcision. Effective prophylactic vaccines are based on type-specific neutralizing antibodies. A major neutralizing epitope is defined by the monoclonal antibody H16.V5. To investigate the importance of this epitope for overall immunogenicity of HPV16, we en

Abstract in UndeterminedUzbekistan, after gaining independence from the Soviet Union in 1991, had publicly declared that it would adhere to democratic governance principles in designing and implementing its public administration policies. As a newly-independent state with democracy claims, Uzbekistan had tried to establish new democratic institutions with an effort to capture international communi

Estimates of relevant source area of pollen (RSAP) and relative pollen productivity (PPE) are critical parameters for quantitative reconstructions of past vegetation and land cover. This study provides estimates for PPE relative to Poaceae for ten taxa, characterizing the cultural landscape of south Estonia and the RSAP for 40 lakes with an average radius of approximately 100 m (22-274 m, average

This thesis aimed to search for epidemiological evidence supporting the associations of type 2 diabetes mellitus (T2DM) with cancer and autoimmune diseases (ADs) by analysing several Swedish national registries. T2DM shares risk factors with cancer, such as obesity, diet, stress, and physical inactivity. However, it is unclear whether the associations with several types of cancers are due to share

1. A new methodological approach for detailed study of the organization of the cerebellar corticonuclear projection was evaluated in barbiturate-anaesthetized cats. Extracellular field potentials were simultaneously recorded in nucleus interpositus anterior and in the forelimb area of the C3 zone, at the cerebellar surface. On electrical and natural stimulation of the forelimb skin, the evoked pos

Background: The Btk (Bruton's tyrosine kinase) gene has been shown to be mutated in the human immunodeficiency disease, XLA (X-linked agammaglobulinemia). Btk is a member of the Tec family of cytosolic protein tyrosine kinases with distinct functional domains PH, TH, SH3, SH2, and kinase. Mutations have been observed in each of the Btk subdomains in XLA. We have analyzed the Btk gene in six XLA pa

Photosynthesis rates and photosynthesis-leaf nutrient relationships were analysed in nine tropical grass and sedge species growing in three different ecosystems: a rain-fed grassland, a seasonal floodplain, and a permanent swamp, located along a hydrological gradient in the Okavango Delta, Botswana. These investigations were conducted during the rainy season, at a time of the year when differences

Recent investigations-of the interaction between DNA and alkyltrimethyl ammonium bromides of various chain lengths are reviewed. Several techniques have been used such as phase map determinations, fluorescence microscopy, and electron microscopy. Dissociation of the DNA-surfactant complexes, by the addition of anionic surfactant, has received special attention. Precipitation maps for DNA-cationic

Extraskeletal myxoid chondrosarcoma (EMC) is a soft-tissue neoplasm cytogenetically characterized by the translocations t(9;22)(q22;q11-12) or t(9;17)(q22;q11), generating EWS/CHN or RBP56/CHN fusion genes, respectively. In the present study, 18 EMCs were studied both cytogenetically and at the molecular level. Chromosomal aberrations were detected in 16 samples: 13 with involvement of 9q22 and 22

Smoking has recently been recognised as causally associated with the development of gastric cancer (GC). However, evidence on the effect by sex, duration and intensity of smoking, anatomic subsite and cessation of smoking is limited. Our objective was to assess the relation between tobacco use and GC incidence in the European Prospective Investigation into Cancer and Nutrition (EPIC). We studied d

Background: Due to its high polymorphism and importance for disease resistance, the major histocompatibility complex (MHC) has been an important focus of many vertebrate genome projects. Avian MHC organization is of particular interest because the chicken Gallus gallus, the avian species with the best characterized MHC, possesses a highly streamlined minimal essential MHC, which is linked to resis

The online-coupled, regional chemistry transport model COSMO-ART is evaluated for periods in all seasons against several measurement datasets to assess its ability to represent gaseous pollutants and ambient aerosol characteristics over the European domain. Measurements used in the comparison include long-term station observations, satellite and ground-based remote sensing products, and complex da

BACKGROUND: The aim of the current study was to investigate the possibility of increasing the maximal tolerated dose (MTD) of a tumor-selective radiolabeled antibody when radioimmunotherapy (RIT) is combined with extracorporeal depletion of radioimmunoconjugates from the circulation. Furthermore, the authors evaluated whether this increase in dose improved the therapeutic effect on solid manifest
