During the last several decades, the scientific and ethics communities have addressed important ethical issues in medical research, resulting in the elaboration and adoption of concepts, guidelines, and codes. Ethical issues in the conduct of Multiregional Clinical Trials have attracted significant attention mainly in the last two decades. With the(More)
Treatment of resident murine peritoneal macrophages with 12-O-tetradecanoyl phorbol-13-acetate (TPA) rapidly converted the cells to tumour cytostatic and cytolytic effector cells, as determined by growth inhibition or lysis of T-lymphoma cells (Eb, EL4) in vitro. The effective TPA concentrations were 10(-8) to 10(-7)M. Macrophages became cytotoxic as early(More)
Prostanoid synthesis is limited by the availability of free arachidonic acid. This polyunsaturated fatty acid is liberated by phospholipases and usually is an intermediate of the deacylation-reacylation cycle of membrane phospholipids. In rat peritoneal macrophages, ethylmercurisalicylate (merthiolate) or N-ethylmaleimide (NEM) dose dependently inhibited(More)
Reliable prediction of the chance of a successful treatment of head and neck squamous cell carcinoma by cytostatics and targeting therapies would be very valuable, since HNSCC due to their heterogenic biology mostly respond non-uniformly and moreover with low response rates. To raise the prospect of chemotherapy by using multimodal therapies usually goes(More)
