    Notizen: Abstract Two ODE models of innovation dynamics based on Grossman and Helpman's endogenousgrowth model with horizontal product differentiation are coupled through knowledge exchange.It is shown that in the coupled model, the steady rates of innovation are asymptotically stabilizedat a unique level higher than the autarky growth rate in each economy. The steady rate ofinnovation common to both countries is positively related to each country's ability to absorbknowledge from abroad. Conditions sufficient for the existence of a steady trajectory areprovided.

    The effect of Keyhole Limpet Hemocyanin (KLH) on the rat bladder (1977)
    Springer
    Cancer immunology immunotherapy 3 (1977), S. 65-67

    Notizen: Summary Immunostimulation with agents such as BCG or KLH may represent an adjuvant therapy in treating patients with bladder cancer. To investigate the effects of direct instillation and injection of KLH into the bladder of sensitized and nonsensitized rats, KLH was injected submucosally into the bladder. Histologically, a marked inflammatory reaction was seen without ulcerations. KLH seems to give a more predictable reaction without the BCG side effects. Intralesional application of KLH, which is now in a clinical trial, may play a role in the treatment of bladder cancer after transurethral resection of the tumor.

    Second generation shock wave lithotripsy: experience with the lithostar (1987)
    Springer
    World journal of urology 5 (1987), S. 225-228

    Notizen: Summary Extracorporeal shock wave lithotripsy (ESWL) has been in clinical use for more than 5 years. Several devices commonly designated “second generation” lithotriptors are now under experimental or clinical trials. A multifunctional lithotriptor unit developed in cooperation with the Siemens Company in Germany is described, which utilizes an electromagnetic mode of shock wave generation along with local coupling to the patient. The results of 795 treatments are presented. The prototype has been in operation since March 1986. Adjuvant endourological measures, all of which have been performed on the same table, include insertion of double-J stents and ureteral catheters prior to ESWL in 27% of all treatments. Shock wave lithotripsy alone has been performed successfully under local anesthesia or a combination of parenteral analgesia and sedation. Results of treatment have been uniformly satisfying.
