The cIII protein of phage lambda favors the lysogenic response to infection by inhibiting the degradation of the lambda cII protein, which exerts the primary control on the developmental decision for lysis or lysogeny. To study the mechanism and scope of cIII-mediated regulation, we have used plasmid systems to examine the specific effect of cIII(More)
For long-term ureteral replacement an artificial ureter has to be able to pump against the outflow resistance into the bladder at any physiological flow rate (0.2-2.0 ml/min). This demand is satisfied only by active prostheses. The active prosthesis described in this paper is driven by the intra-abdominal pressure fluctuations caused by the respiratory(More)
