1. 1. Sharp Bounds for Calderón-Zygmund Operators in a Vector-Valued Setting

   Sammanfattning : In this thesis we extend several classical results about Calderón-Zygmund operators to spaces of vector-valued functions. We first obtain bounds for the norm of dyadic Haar shift operators using a Bellman function technique, and then apply the representation theorem to obtain corresponding results for general Calderón-Zygmund operators.

3. 2. Proteoglycans, group IIA phospholipase A2, and lipoproteins.Potential involvement in atherogenesis

   Författare :Peter Sartipy; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; group IIA phospholipase A2; proteoglycans; lipoproteins; inflammation;

   Sammanfattning : Atherosclerosis is a multifactorial complex disease characterized by a focal accumulation of ApoB-100 containing lipoproteins, extracellular matrix (ECM), and cells in the arterial intima accompanied by an inflammatory reaction. In vivo and in vitro data supports the hypothesis that sulfated extracellular proteoglycans may be responsible for the selective retention of low density lipoproteins (LDL) in the arterial wall.
