SummaryAn experimental model incorporating cultured endothelial cells (EC) was used to study the "factor VIII bypassing" activity of prothrombin complex concentrates (PCC), a property exploited in the treatment of hemophiliacs with alloantibodies to factor VIII. Two PCC preparations were ineffective as stimuli of tissue factor expression by EC. However, incubation with a combination of PCC plus endotoxin (lipopolysaccharide, LPS) or tumor necrosis factor (TNF) induced much greater tissue factor expression than was seen in response to either substance alone. PCC expressed an additional direct procoagulant activity at the EC surface, which could not be attributed to either thrombin or factor Xa, and which was diminished by an anti-tissue factor antibody. Therefore factor VIIa, which was detectable in both PCC preparations, likely provided this additional direct procoagulant activity at the EC surface. We also excluded the possibility that coagulation proteases contained in or generated in the presence of PCC are protected from inactivation by AT III. Therefore, PCC can indirectly bypass factor VIII by enhancing induced endothelial tissue factor expression, and also possess direct procoagulant activity, probably mediated by factor VIIa.

SummaryWhite blood cells can no longer be considered simple trapped inclusions within thrombi. Their numbers in thrombi relative to blood counts increase with time. They appear to come from the blood flowing past the thrombus. They appear to migrate by amoeboid movement into the thrombic mass. Polymorphonuclear neutrophils have been shown to be lytic to fibrin and other proteins and thus can contribute to thrombus dissolution. There is increasing evidence that neutrophils may impart important cytotrophic function to proliferating cells during thrombus organization. Eosinophils are known to carr profibrinolysin and will release this precursor at sites of fibrin deposition. Mononuclear leukocytes can transform into fibroblasts in tissue culture and I consider a thrombus an ideal tissue culture medium. All of these cells can contribute to thrombus dissolution simply by mechanical weakening of the mass by migration into it, releasing enzymes, and allowing blood flow to carry away pieces of the thrombus as emboli. I extend my perspective on thrombosis by considering these intravascular solids as cell tissue cultures rather than simple blood clots or platelet aggregates.

‘‘Proteomics’’, is the emerging technology leading to high-throughput identification and understanding of proteins. Proteomics is the protein equivalent of genomics and has captured the imagination of biomolecular scientists, worldwide. Because proteome reveals more accurately the dynamic state of a cell, tissue, or organism, much is expected from proteomics to indicate better disease markers for diagnosis and therapy monitoring. Proteomics is expected to play a major role in biomedical research, and it will have a significant impact on the development of diagnostics and therapeutics for cancer, heart ailments and infectious diseases, in future. Proteomics research leads to the identification of new protein markers for diagnostic purposes and novel molecular targets for drug discovery.  Though the potential is great, many challenges and issues remain to be solved, such as gene expression, peptides, generation of low abundant proteins, analytical tools, drug target discovery and cost. A systematic and efficient analysis of vast genomic and proteomic data sets is a major challenge for researchers, today. Nevertheless, proteomics is the groundwork for constructing and extracting useful comprehension to biomedical research. This review article covers some opportunities and challenges offered by proteomics.
