Background: Recent analyses in Greenlandic Inuit identified six genetic polymorphisms (rs74771917, rs3168072, rs12577276, rs7115739, rs174602 and rs174570) in the fatty acid desaturase gene cluster (FADS1-FADS2-FADS3) that are associated with multiple metabolic and anthropometric traits. Our objectives were to systematically assess whether dietary polyunsaturated fatty acid (PUFA) intake modifies
Air pollution is responsible for one in eight premature deaths worldwide, and thereby a major threat to human health. Health impact assessments of hypothetic changes in air pollution concentrations can be used as a mean of assessing the health impacts of policy, plans and projects, and support decision-makers in choices to prevent disease. The aim of this study was to estimate health impacts attri
Some polycyclic aromatic hydrocarbons (PAH) are known carcinogens and workplace PAH exposure may increase the risk of cancer. Monitoring early cancer-related changes can indicate whether the exposure is carcinogenic. Here, we enrolled 151 chimney sweeps, 152 controls, and 19 creosote-exposed male workers from Sweden. We measured urinary PAH metabolites using LC/MS/MS, the cancer-related markers te
Background/Objectives:Obesity and low physical fitness are known risk factors for ischemic heart disease (IHD), but their interactive effects are unclear. Elucidation of interactions between these common, modifiable risk factors may help inform more effective preventive strategies. We examined interactive effects of obesity, aerobic fitness and muscular strength in late adolescence on risk of IHD
To address the importance of antigen-presenting cells for the survival of intracerebral neural allografts, allogeneic spleen cells were added to the graft tissue before transplantation. Dissociated embryonic, dopamine-rich mesencephalic and adult spleen tissues were prepared from either inbred Lewis or Sprague-Dawley rats. A mixture of neural and spleen cells was sterotaxically transplanted into t
The host response to immunologically incompatible intrastriatal neural grafts was studied using immunohistochemical techniques. Dissociated ventral mesencephalic tissue from embryonic donors of either syngeneic, allogeneic or xenogeneic (mouse) origin was stereotaxically implanted into adult rats. The brains were analysed 4 days, 2 weeks or 6 weeks after grafting with antibodies against the follow
Background: Electrodermal reactivity has been successfully used as indicator of interest, curiosity as well as depressive states. The measured reactivity depends on the quantity of sweat secreted by those eccrine sweat glands that are located in the hypodermis of palmar and plantar regions. Electrodermal hyporeactive individuals are those who show an unusual rapid habituation to identical non-sign
Background Human epidermal growth factors 2 and 3 (HER2 and HER3) are members of the EGFR family that drives oncogenesis mainly through activation of the RAS-RAF-MEK-ERK pathway. While the prognostic value of HER2 and HER3 alterations in colorectal cancer (CRC) remains uncertain, KRAS and BRAF mutations confer resistance to targeted therapies and poor prognosis. Sidedness of the primary tumour has
In order to reduce nitrogen oxides (NOx) and soot emissions while maintaining high thermal efficiency, more advanced combustion concepts have been developed over the years, such as Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), as possible combustion processes in commercial engines. Compared to HCCI, PPC has advantages of lower unburned hydrocarbon (UHC) an
Classroom interaction engendered by different form-and-accuracy exercises with advanced students This presentation focuses on the impact of two different kinds of form-and-accuracy grammar exercises on teacher-student classroom interaction with advanced Swedish-speaking L2 users of English. The purpose is to explore whether the exercises lead to a) the same amount and type of interaction, and b)
Popular Abstract in Swedish Fosterövervakning under förlossningen är standard inom förlossningsvården. Målet är att identifiera avvikande händelser och då speciellt syrebrist hos fostret. Sedan början på sjuttiotalet har vågformsanalys av foster EKG studerats ur fysiologisk, klinisk och signal synpunkt. Vågformen hos ett EKG innehåller mer information än bara R-R intervallet i ett EKG dvs konventiWaveform analysis of the fetal electrocardiogram has been studied since the early seventies from both physiological, signal processing and clinical aspects. It has been found to contain more useful information than the mere detection of RR-intervals (fetal heart rate), e.g., the ST-segment giving evidence of the ability of fetal myocardium to respond to the stress of labor. In the Swedish RCT, STA
This thesis includes four appended papers. The thesis describes the challenges and advantages of the use of FE-analysis in the design of a component forming process in the automotive industry. Today, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods in each stage of the process development chain. In order to decrease the lon
Fuel cells produce low quantities of local emissions, if any, and are therefore one of the most promising alternatives to internal combustion engines as the main power source in future vehicles. It is likely that urban buses will be among the first commercial applications for fuel cells in vehicles. This is due to the fact that urban buses are highly visible for the public, they contribute signifi
Popular Abstract in Swedish En av de viktigaste substanserna i vår kropp är proteiner, också kallade äggviteämnen. Proteiner har en mängd olika uppgifter i kroppen, de finns i våra celler där de har olika uppgifter såsom att fungera som enzymer, transportörer, signalsubstanser, eller som skyddsfaktorer. Proteiner ingår också som viktiga beståndsdelar i vävnaderna mellan cellerna och finns dessutomPathogenic bacteria express a wide array of surface proteins that interact with the environment. Many of these proteins are believed to be important for the virulence. This thesis deals with the binding of immunoglobulins (Ig) and complement regulating proteins to certain bacterial surface proteins. Protein L from Peptostreptococcus magnus binds to Igk-light chains while protein A from Staphylococ
Mammalian mitochondrial DNA (mtDNA) is a closed-circular double-helix molecule which contains two rRNA genes, 13 protein-coding genes, and 22 tRNA genes. The molecule has become a popular tool in phylogenetic analyses owing to its relatively high evolutionary rate, simple genetic structure, small size, and compact gene arrangement. The order Perissodactyla includes the extant families Equidae, Ta
Popular Abstract in Swedish Malaria och tuberkulos är två av de mest dödliga infektionssjukdomarna i världen. Biologiskt är de två infektionerna mycket olika; malaria orsakas av en encellig parasit, en plasmodium, som sprids mellan personer med hjälp av myggbett, och tuberkulos av en bakterie som sprids via upphostade bakterier. Vidare drabbar malaria vanligtvis blodomloppet medan tuberkulos oftasMalaria and tuberculosis are two of the most deadly infectious diseases that exist. Both diseases predominantly affect the most vunerable parts of society. Additionally the treatment of both diseases are complicated by growing and spreading resistance against the drugs used to treat them. Chloroquine was once described as a wonder drug for its combination of efficacy, low price and tolerable side
Popular Abstract in Swedish Avhandlingens syfte är att belysa relationerna mellan lokal praktik och statlig styrning med utgångspunkt i hur efterkrigstidens välfärdspolitik förändrade livsbetingelserna i ett antal byar i norra Sveriges inland. Tre teman knyter samman diskussionen. Det första temat knyts till frågorna kring hur det nordsvenska inlandet omvandlats under efterkrigstiden och till hur
