The aim of the present study was to test for possible associations between candidate gene polymorphisms and the risk of restenosis and recurrent restenosis after percutaneous transluminal coronary angioplasty (PTCA) without stenting. We followed up 511 PTCA patients, and restenosis and recurrent restenosis were defined according to angiographical criteria. Genotyping of the beta-fibrinogen -455...

Autologous stem cell transplantation is used to rescue cancer patients from myelosuppression caused by high-dose chemotherapy. However, autologous grafts often contain tumor cells that can contribute directly to relapse. Current purging methods are useful when fewer than 1% tumor cells contaminate the bone marrow, and patients with tumor burdens of >1% are considered ineligible for chemotherapy...

Human factor V is activated to factor Va by alpha-thrombin after cleavages at Arg709, Arg1018, and Arg1545. Factor Va is inactivated by activated protein C (APC) in the presence of a membrane surface after three sequential cleavages of the heavy chain. Cleavage at Arg506 provides for efficient exposure of the inactivating cleavages at Arg306 and Arg679. Membrane-bound factor V is also inactivat...

Pseudomonas syringae pv. tomato race 1 strains have evolved to overcome genetic resistance in tomato. Here, we present the draft genome sequences of two race 1 P. syringae pv. tomato strains, A9 and 407, isolated from diseased tomato plants in California.

abstract atrazine biodegradation by bacteria is one of the most important aspects of bioremediation. atrazine can be degraded by various species of bacteria. bacteria use atrazine as nitrogen and carbon sources. the aim of this study was to determine atrazine degradation by pseudomonas fluorescence and pseudomonas aeruginosa. the experiment consisted of two pseudomonas bacteria, three levels of...

The efficacy of the topoisomerase I inhibitor 7-ethyl-10-(4-[1-piperidino]-1-piperidino)-carbonyloxy-camptotheci n (irinotecan, CPT-11) has been examined against a panel of six independently derived neuroblastoma xenografts. Intensive courses of therapy, where irinotecan was administered i.v. daily 5 days per week for two consecutive weeks [(dx5)2; defined as 1 cycle], were compared to more pro...
