Antigen presentation to T cells by MHC molecules is essential for adaptive immune responses. To determine the exact position of a gene affecting expression of MHC molecules, we finely mapped a previously defined rat quantitative trait locus regulating MHC class II on microglia in an advanced intercross line. We identified a small interval including the gene MHC class II transactivator (Mhc2ta) and

This study considers astrophysics, stellar and nebular astronomy in Sweden. Emphasis is on the role of scientific technologies and practice, and the emergence of a modern observational astronomy, supplanting classical astronomy as the most vital field of Swedish astronomy. The introduction of photography and spectroscopy is discussed, mainly focused on Nils Dunér. The mechanical nature of the pho

The interaction between three triblock copolymers of poly(ethylene oxide) and poly(propylene oxide), EOnPOmEOn, and the ionic surfactants sodium dodecyl sulfate, SDS, and hexadecyltrimethylammonium chloride, CTAC, has been studied in dilute aqueous solution using differential scanning calorimetry, DSC, and isothermal titration calorimetry. The length of the PPO block was the same in all three copo

OBJECTIVE: The reason that only a minority of smokers develop chronic obstructive pulmonary disease (COPD) is still largely unknown. Glycosylation defects are involved in the pathological mechanisms in cystic fibrosis (CF), where chronic progressive obstructive lung disease dominates the clinical picture. Whether defects of protein glycosylation occur in COPD has not previously been examined. Incr

Study of the European reception of the violent films of Sam Peckinpah in the late 1960s and early 1970s.

Danish social policies have a gender neutral approach, combined with an aim of autonomy for individuals and a system of universal social policies. This approach has moved Denmark away from the use of moral regulation of single mothers and a strong male income earner model in social policy. It has highlighted men's roles as fathers, as well as women's roles as workers and has therefore a lot of adv

Popular Abstract in Swedish Avhandlingen behandlar kapacitet i cirkulationsplatser. Kapaciteten för ett körfält i en tillfart kan beräknas med teorin för kritiska tidsavstånd. Denna bygger på interaktioner mellan fordon med företräde (överordnade fordon) och fordon som skall lämna företräde (underordnade fordon). Det kritiska tidsavståndet är det minsta tidsavstånd mellan två överordnade fordon soProblem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. Various components of this theory are discussed, models for headways in the multi-lane case and for the estimation of critical gaps for the two major streams being developed and being applied

Two different red pigments used for tattooing were found to give rise to inflammatory reactions in the skin. No inorganic component was found in the pigments. NMR and MS analyses elucidated the molecular structures of two different organic compounds. A bright red pigment was found to be an aromatic azo-derivative, and a red-violet pigment was found to be linear quinacridone. A strong exposure to U
