During the last decade, a multitude of experimental evidence has accumulated showing that low-dose radiation therapy (single dose 0.5-1 Gy) functionally modulates a variety of inflammatory processes and cellular compounds including endothelial (EC), mononuclear (PBMC) and polymorphonuclear (PMN) cells, respectively. These modulations comprise a hampered(More)
Bone matrix, mainly composed of type I collagen and apatite, is constantly modified during the bone remodeling process, which exposes bone cells to various proportions of mineralized collagen within bone structural units. Collagen-mineralized substrates have been shown to increase osteoblast activities. We hypothesized that such effects may be explained by(More)
Multipotent mesenchymal cells (MMCs) differentiate into osteoblasts or adipocytes through RUNX2 and PPARγ2, respectively. Strontium ranelate has been shown to promote osteoblastogenesis and prevent adipogenesis in long-term experiments using MMCs. The present study involved in-vitro and in-vivo investigations of whether Sr might first be an inhibitor of(More)
Binding of lipoprotein(a) (Lp(a)) to membrane proteins of the monocyte-macrophage cell lineage may be an important event in atheroma formation. Since Lp(a) with distinct apolipoprotein(a) (apo(a)) isoforms may show differences in their affinity with regard to fibrin binding, the existence of such a functional behavior in the interaction of apo(a) in Lp(a)(More)
Molecular assembly of plasminogen and tissue-type plasminogen activator (t-PA) at the surface of fibrin results in the generation of fibrin-bound plasmin and thereby in the dissolution of a clot. This mechanism is triggered by specific interactions of intra-chain surface lysine residues in fibrin with the kringle domains of plasminogen, and is further(More)
The purpose of this work was to identify an unknown component which has been detected during the analysis of cyclic fatty acid monomers (CFAMs) in low erucic acid rapeseed oils (LEAR). A sample of crude LEAR was transformed into fatty acid methyl esters (FAMEs) and hydrogenated using PtO(2). The hydrogenated sample was fractionated by reversed-phase(More)
Collagen arthritis is an experimental model for rheumatoid arthritis which is induced in susceptible DBA/1 mice after immunization with native type II collagen (CII). All immunized mice exhibit a humoral response to CII regardless of the occurrence of articular pathology. In order to further analyze the determinants recognized on the CII molecule, we have(More)
