Stopped-flow fluorescence studies were performed to investigate the kinetics of formation of complexes between DNA and cationic vesicles. We followed the kinetics as a function of charge ratio and lipid vesicle composition. Binary mixtures of a saturated cationic lipid, dioctadecyldimethlammonium bromide (DODAB), and a zwitterionic lipid, dioleoylphosphatidylethanolamine (DOPE), were used to prepa
The aim of this study was to examine platelet function after coronary artery bypass grafting (CABG) with and without the use of extracorporeal circulation (ECC). Sixteen male patients scheduled for CABG with (n = 8) and without (n = 8) ECC were included in the study. Platelet retention, as measured with a glass-bead retention test, was examined daily during the first postoperative week. Von Willeb

An analysis of the Danish project "The Mediation of History".
Rationale and Objectives. To find signs in vector-electrocardiography (VECG) predicting the ventricular fibrillatory propensity (VF-PROP) of iodixanol and mannitol solutions after injection into the left coronary artery (LCA) of pigs. Materials and Methods. Five plasma-isotonic solutions perfused LCA: lod 320 + Na/Ca (iodixanol 320 mg I/mL, 19 mM NaCl, 0.3 mM CaCl2), lod 320 + Mann (iodixanol 320
A folder in the Ericsberg archive contains a rare collection of small ephemera printed to be used as theatre posters, advertisements for fanciful shops, pharmaceutical labels on imaginary medicines, lottery tickets etc. at a 1749 christmas party at the court of Queen Lovisa Ulrika of Sweden. The festivity was organized as a street market inside the palace by the Chancellor Count Tessin, and the te
The glacial unloading and resulting isostatic land uplift have together with hydro-isostasy, eustatic rise of sea-level and geoidal changes, ruled the shore displacement of Fennoscandia. Within the Baltic basin, periods of damming and shifts of outlet further complicated the shore displacement during the period studied, c. 12,200-8400 BP. Information on the Baltic history was derived from shorelin
This paper explores the incentives in the two cornerstones of the regulatory effort: the legislative decisions on specific regulations and the day-to-day activities of the officials at the Labour Inspectorate. It is argued that there have been and probably will continue to be pro-safety incentives at the legislative level. Until 1992, representatives of employers' and employees' organizations were
We investigate the effects of adaptive time-stepping and other algorithmic strategies on the computational stability of ODE codes. We show that carefully designed adaptive algorithms have a most significant impact on computational stability and reliability. A series of computational experiments with the standard implementation of Dassl and a modified version, including stepsize control based on di
Popular Abstract in Swedish Arbetet i denna avhandling syftar till att utveckla bättre ljuskällor för fluorescensavbildning och fotodynamisk behandling av cancertumörer. Små kompakta diodlasrar är ideala ljuskällor för detta, men en del kliniska användningar kräver att deras prestanda förbättras. Gemensamt för de bägge diagnostik- och behandlingsmetoderna är att man behöver uppnå högre strålkvalitThis work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatmen
Popular Abstract in Swedish Denna avhandling undersöker den operativa kärnan i räddningsinsatser. Vidare undersöker den effekten av olika åtgärder som används vid räddningsinsatser mot brand i byggnad, effekten av sådana åtgärder till följd av beslut som fattas av befäl samt effekten av att allokera resurser i tiden och rummet vid en räddningsinsats mot brand i byggnad. Avhandlingen drar slutsatseThe operational core of firefighting operations was examined. The effects of various firefighting procedures on the fire ground, their impact upon conditions on the fire ground in which decisions by commanding officers are made and the effects of allocating resources in time and space on the fire ground were explored. In addition, various approaches for modelling firefighting operations were discu
Background/aims: Mutans streptococci are found in almost all individuals, though there are large differences in colonization levels between individuals. These differences are not readily explained, though several factors are believed to influence the colonization. One factor is the immune response to mutans streptococci, mainly provided by salivary immunoglobulin A (IgA). In a previous study, diff
Background and aims: The primary aim of the present study was to examine whether there is an association between blood pressure and the risk of subsequent cognitive decline in the oldest old. Various factors associated with blood pressure and cognitive function were considered. Methods: The study comprised 599 individuals of a population-based sample, 199 men (mean age at baseline 82.8 years, rang
This paper presents a strategy for closed-loop control of a multi-cylinder turbocharged Homogeneous Charge Compression Ignition (HCCI) engine. A dual fuel port injection system allows control of combustion timing and load individually for each cylinder. The two fuels used are isooctane and n-heptane, which provides a wide range of autoignition properties. Cylinder pressure sensors provide feedbac
