Alterations in human hemoglobin structure related to red blood cell storage (2011)
Rasha Bassam ; Gerhard Artmann ; Jürgen Hescheler ; T. Graef ; Aysegül Temiz Artmann ; Dariusz Porst ; Peter Linder ; Peter Kayser ; Vladimir Arinkin ; Matthias Gossmann ; Ilya Digel
The importance of the availability of stored blood or blood cells, respectively, for urgent transfusion cannot be overestimated. Nowadays, blood storage becomes even more important since blood products are used for epidemiological studies, bio-technical research or banked for transfusion purposes. Thus blood samples must not only be processed, stored, and shipped to preserve their efficacy and safety, but also all parameters of storage must be recorded and reported for Quality Assurance. Therefore, blood banks and clinical research facilities are seeking more accurate, automated means for blood storage and blood processing.
Engineering technology for plant physiology and plant stress research (2011)
C. Preiß ; Peter Linder ; K. Wendt ; M. Krystek ; Ilya Digel ; Matthias Gossmann ; Aysegül Temiz Artmann ; Dariusz Porst ; Peter Kayser ; Rasha Bassam ; Gerhard Artmann
Plant physiology and plant stress: Plant physiology will be much more important for human mankind because of yield and cultivation limits of crops determined by their resistance to stress. To assess and counteract various stress factors it is necessary to conduct plant research to gain information and results on plant physiology.
Ureplace: development of a bioreactor for in vitro culturing of cell seeded tubular vessels on collagen scaffolds (2011)

The demand of replacements for inoperable organs exceeds the amount of available organ transplants. Therefore, tissue engineering developed as a multidisciplinary field of research for autologous in-vitro organs. Such three dimensional tissue constructs request the application of a bioreactor. The UREPLACE bioreactor is used to grow cells on tubular collagen scaffolds OPTIMAIX Sponge 1 with a maximal length of 7 cm, in order to culture in vitro an adequate ureter replacement. With a rotating unit, (urothelial) cells can be placed homogeneously on the inner scaffold surface. Furthermore, a stimulation is combined with this bioreactor resulting in an orientation of muscle cells. These culturing methods request a precise control of several parameters and actuators. A combination of a LabBox and the suitable software LabVision is used to set and conduct parameters like rotation angles, velocities, pressures and other important cell culture values. The bioreactor was tested waterproof successfully. Furthermore, the temperature controlling was adjusted to 37 °C and the CO2 - concentration regulated to 5 %. Additionally, the pH step responses of several substances showed a perfect functioning of the designed flow chamber. All used software was tested and remained stable for several days.
