1. 26. Variable surface molecules of the plasmodium falciparum infected erythrocyte and merozoite

   Författare :Malin Haeggström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :P.falciparum; infected erythrocytes; transport; Maurer s clefts; antigenic variation; PfEMP1; RIFIN; SURFIN; merozoites; subgroups;

   Sammanfattning : As Plasmodium falciparum parasites matures within the infected erythrocyte (IE) it produces a number of various proteins, which are transported out to the cell surface where they are exposed to the host immune system. To avoid recognition and elimination by the liver and spleen these proteins can undergo antigenic variation, a phenomenon where the parasites switch from expressing one variant to' another, both belonging to the same gene-family.

3. 27. Computational Aspects of Maass Waveforms

   Författare :Fredrik Strömberg; Dennis A. Hejhal; Andreas Strömbergsson; David Farmer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Maass waveform; Congruence subgroup; Noncongruence subgroup; Multiplier system; Theta multiplier system; Eta multiplier system; real weight; Hecke operator; Involution; Dirichlet character; Spectral Theory; Computation; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

   Sammanfattning : The topic of this thesis is computation of Mass waveforms, and we consider a number of different cases: Congruence subgroups of the modular group and Dirichlet characters (chapter 1); congruence subgroups and general multiplier systems and real weight (chapter 2); and noncongruence subgroups (chapter 3). In each case we first discuss the necessary theoretical background. LÄS MER

4. 28. Some applications of representation theory in homogeneous dynamics and automorphic functions

   Författare :Samuel Charles Edwards; Andreas Strömbergsson; Henrik Schlichtkrull; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automorphic functions; effective equidistribution; Eisenstein series; homogeneous dynamics; horospheres; lattices; Lie groups; representation theory; Mathematics; Matematik;

   Sammanfattning : This thesis consists of an introduction and five papers in the general area of dynamics and functions on homogeneous spaces. A common feature is that representation theory plays a key role in all articles. LÄS MER

5. 29. Swedish young offenders in community-based rehabilitative programmes : Patterns of antisocial behaviour, mental health, and recidivism

   Författare :Hanna Ginner Hau; Ann-Charlotte Smedler; Philip Hwang; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Young offenders; Rehabilitation; Adolescence; Developmental psychology; Prevention; Risk assessment; Juvenile justice; Recidivism; Mental health; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : The overall aim of this thesis was to explore patterns of antisocial behaviour, mental health and recidivism among Swedish young offenders in community-based rehabilitative programmes (n=189). Study I explored the character and severity of self-reported behavioural problems prior to programme participation. LÄS MER

7. 30. Molecular Characterization of Male Breast Cancer

   Författare :Ida Johansson; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; male breast cancer; aCGH; gene expression; DNA-methylation; microarray; profiling; NAT1; THY1;

   Sammanfattning : Cancer is today a major healthcare problem worldwide. There are many forms of cancer, which is a genetic disease, believed to result from a multistep process with genetic and epigenetic changes accumulating over time. Breast cancer is one of the most common forms of cancer in women, while it is much more rare in men. LÄS MER
