Aggressive lymphoma is a rapidly growing tumour of lymphocyte origin, potentially curable with chemotherapy. In a trial by the Nordic Lymphoma Group, 405 patients with aggressive lymphoma were included, and randomised to receive either the standard chemotherapy regimen, CHOP, or a weekly multidrug regimen, MACOP-B. In this trial, MACOP-B was not superior in terms of response, failure-free or overa
The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. Speciation in sympatry, i.e. without any isolation between the
The importance of early detection of brain changes during ageing has been recognised. Single photon emission computed tomography (SPECT) is a method used for estimation of cerebral blood flow (CBF) in clinical work and in research. The aim of thesis was to study CBF in demented and non-demented elderly persons with special reference to blood pressure changes. Elderly women with senile dementia of
The homologous blood coagulation factors V (FV) and factor VIII (FVIII) are important at sites of vascular injury for the amplification of the clotting cascade. Activated FV (FVa) serves as a cofactor to the enzyme activated factor X (FXa) in the activation of prothrombin. This complex is called the prothrombinase complex. FVIII functions as a cofactor to the enzyme activated factor IX (FIXa) in t
The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. Oxygen atom transfer reactions involving oxomolybdenum bis-dithiolene complexes have been modelled using density functional calculations. The first molybden
Neuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. Their expression of genes and proteins that regulate normal sympathetic development and cell cycle/cell death regulators was a
Boken innehåller praktiska övningar på moment inom olika delar av grammatiken: morfologi och ordklasser, ordbildning, syntax och språklig variation. Till övningarna finns facit med kommentarer. Kategoriseringarna och användningen av termer bygger på läroboken Svensk universitetsgrammatik för nybörjare, som i stort behandlar samma stoff. Övningsboken fungerar dock oberoende av läroboken, eftersom v
The studies in this doctoral thesis investigated how home literacy, self regulation, academic self-concept, and goal orientation influence reading ability. Study 1 investigated the effect of family-based prerequisites, reading attitude, and self-regulated learning on reading ability. Students (n= 4,018) in the eighth grade answered the IEA reading literacy test and the SRLQ. Structural Equation Mo
The ABO blood group system is undoubtedly the most important genetic and phenotypic marker in clinical transfusion medicine. The A and B determinants are immunodominant, terminally located carbohydrate residues of glycoconjugates on erythrocytes and other cell surfaces. The enzymes responsible for assembly of these structures are glycosyltransferases encoded by the ABO genes on chromosome nine. T
En genomgång av hur de grammatiska delarna av ordboksartiklar om prepositioner har behandlats terminologiskt i Svenska Akademiens grammatik (1893–).
C4b-binding protein (C4BP) is an acute-phase plasma glycoprotein which regulates the complement system through its affinity for C4b. In addition, C4BP binds to the anticoagulant protein S and to serum amyloid P component (SAP). Protein S is a vitamin K-dependent protein which looses its anticoagulant properties when binding to C4BP. C4BP is composed of two types of subunits, the a-chain and the b-
Abstract in Norwegian At eierskap kan uttrykkes på flere måter i språk, er kjent, og også at ulike typer eierskapsrelasjoner uttrykkes ulikt innenfor ett og samme. Imidlertid finnes det noen misoppfatninger når det gjelder norsk, som at norsk bare har et rudimentært system for eierskapskategorier (Stolz et al. 2008). Vi viser at norsk tvert imot har et rikt system av kategorier og uttrykksformer.
Leukemic cells suffer from an impaired ability to differentiate due to inherited or acquired genetic lesions. These genetic changes can sometimes be bypassed with various compounds both in vitro, and, more rarely, in vivo, thus inducing terminal differentiation of the leukemic cells. Differentiation of both leukemic and normal hematopoietic cells is believed to be intimately coupled to cell cycle
