Popular Abstract in Swedish För att skydda sig mot infektioner har människan ett välutvecklat immunförsvar. I immunförsvaret ingår många olika celler och proteiner (äggviteämnen). Till exempel finns det celler som producerar antikroppar som specifikt känner igen bakterier och virus som en människa har utsatts för vid en tidigare infektion. Det finns också speciella celler som kan fagocytera (äta uMany microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. This thesis describes studies of such interactions between human C4b-binding protein (C4BP),

Biografisk artikel om Sofia Holmgren (1864-1953), en av Lunds universitets tidiga kvinnliga medicinstuderande, läkare, sexualupplysare och engagerad i kvinnorörelsen.

Popular Abstract in Swedish Vårt immunsystem är uppbyggt runt två typer av celler som har som uppgift att försvaraoss mot infektioner. T lymfocyterna står för det cellmedierade immunförsvaret som är speciellt viktigt för att bekämpa virusinfektioner med B lymfocyterna har som uppgift att producera antikroppar. Antikroppar finns i alla kroppsvätskor och kan interagera med toxiner, virus och bakteriEach immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. Therefore, the activity of other co-stimulatory elements is required. This investigation has focused on the study

Over the past few decades new cities have appeared around the world in undeveloped areas. And although development has expanded significantly and become bolder and more innovative, the above-average scale at which the countries of the Persian Gulf are growing stands one level above the rest. The United Arab Emirates obtained independence in 1971 with a GDP of 6.5 billion Dirhams (US$ 1.6 billion);

Existing econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The current paper takes these shortcomings as a starting point to develop a factor analytical approach that mak

Radiative lifetimes have been studied in neutral copper, gold, magnesium, zinc, tellurium, sulphur, selenium, bismuth and helium and in singly ionised platinum and palladium. The radiative lifetimes were determined by time-resolved spectroscopy following single, two-photon or stepwise laser excitation. The excitations required short wavelengths, obtained by frequency mixing of radiation from pulse

The study reports on the practices of illegal file sharing in Sweden during the period 2007-2012. More than 1.000 posts in response to the question “You guys who download stuff illegally, don’t you ever feel guilty?” where analyzed with regard to the respondents’ expressed senses of guilt, whether file sharing was right or wrong, if they buy media, together with dimensions of stakeholders and medi
