Switching properties of supersymmetric quantum mechanics

In a preceding paper a dynamical form of supersymmetry breaking was considered within the framework of supersymmetric quantum mechanics. Out of these attempts a whole hierarchy of models has developed, in whic...

Ex vivo stimulation of renal transport of the cytostatic drugs methotrexate, cisplatin, topotecan (Hycamtin) and raltitrexed (Tomudex) by dexamethasone, T3 and EGF in intact human and rat kidney tissue and in human renal cell carcinoma

Previous experiments have shown that both in vivo and in vitro pre-treatment with various hormones increases the renal transport capacity for weak organic acids, such as PAH, in rats. The aim of the present s...
