Reconfigurable systems for sequence alignment and for general dynamic programming.

Reconfigurable systolic arrays can be adapted to efficiently resolve a wide spectrum of computational problems; parallelism is naturally explored in systolic arrays and reconfigurability allows for redefinition of the interconnections and operations even during run time (dynamically). We present a reconfigurable systolic architecture that can be applied for the efficient treatment of several dynamic programming methods for resolving well-known problems, such as global and local sequence alignment, approximate string matching and longest common subsequence. The dynamicity of the reconfigurability was found to be useful for practical applications in the construction of sequence alignments.

Management and outcome of bilateral testicular germ cell tumors: Twenty-five year experience in Munich.

We analyzed characteristics, therapy and outcome of patients with bilateral testicular germ cell tumor (TGCT) at our institutions. Among 1,180 TGCT patients diagnosed and/or treated between 1979 and 2003, 47 (4.0%) developed a second TGCT.

Ultrasound screening for internal jugular vein thrombosis aids the detection of central venous catheter-related infections in patients with haemato-oncological diseases: a prospective observational study.

To prove the hypothesis that central venous catheter-related thrombosis and infection are associated, 43 haemato-oncological patients with an internal jugular vein catheter underwent ultrasound screening for thrombosis every 4 d. Catheter-related thrombosis was detected in 13/43 patients (30%). Catheter-related infection, as defined by the U.
