In summary, the incidence of mechanical renal replacement therapy in critically ill patients suffering from oliguric acute renal failure could not be altered positively by Ularitide administration according to our protocol. Further prospective clinical trials are needed to answer the question whether a different patient collective or a prophylactic administration of Ularitide are more promising approaches in the clinical setting of oliguric acute renal failure.

BaF2, PbF2, and CaF2 films are investigated by IRAS (infrared reflection absorption spectroscopy), ATR (attenuated total reflection), IR transmission measurements, and IR ellipsometry. Interesting features of their spectra particularly occur near 300, 1500, and 3000 cm−1. These absorptions are due to intrinsic modes, hydroxyl, and methylen, respectively. The frequencies of the vibrational modes are related to the film material, but also to its history. The so called longitudinal optical frequencies roughly coincide with corresponding values for the cubic modifications of the fluorides, where the F ions are tetrahedrically surrounded by four nearest neighbour metal ions. Polarization dependent measurements hint at an anisotropic incorporation of water molecules in some cases. According to the lower melting point of PbF2 its water content can be reduced by heating above 373 K more quickly than it is possible for BaF2 films. This is proved by ATR measurements.

Sputtered and evaporated optical Ge films are investigated using electron microscopy and diffraction, total integrated scattering, infrared reflection absorption spectroscopy, Auger electron spectroscopy, and optical transmission measurements to observe differences of the chemical composition, atomic structure, morphology, optical constants, and degradation in relation to the parameters of technology during preparation.

Visible light scattering as well as absorption measurements have been made on sputtered Ta2O5 single layers with changing the optical thickness of the film. Comparison of the results experimentally observed with those obtained from theory allowed conclusions to be drawn with respect to the dominant origins of scattering and absorption losses
