In Forschung und Praxis mangelt es bislang an einer weitreichenden Diskussion bezüglich der strategischen Bedeutung von Green IT und derzeit existiert kein Rahmenwerk für die Harmonisierung von Nachhaltigkeitsund ITStrategie. Dieser Forschungsbeitrag adressiert deshalb dieses Thema und soll Möglichkeiten aufzeigen, Green IT nicht nur zur Senkung operativer Kosten sondern auch als Differenzierun...
Objectives: Prone hip extension (PHE) is a commonly used test to investigate the extensor activation pattern in the lumbo-pelvic area. It has been belived that performing abdominal stabilization maneuvers during PHE may change the pattern of lumbo-pelvic muscles activity. No study has yet assessed the muscular activation pattern during PHE with and without abdominal bracing (AB) to activate all...
Glutamate is the primary excitatory neurotransmitter in the central nervous system. Excessive concentrations of glutamate in the brain can be excitotoxic and cause oxidative stress, which is associated with Alzheimer's disease. In the present study, the effects of vitamin E in the form of tocotrienol-rich fraction (TRF) and alpha-tocopherol (α-TCP) in modulating the glutamate receptor and neuro...
It is known that some polynomial mappings φ : Ck → Cn are recti able in the sense that there exists a polynomial mapping α : Cn → Cn whose inverse is also polynomial and for which α(φ(z1, . . . , zk)) = (z1, . . . , zk, 0, . . . , 0) for all z1, . . . , zk. In many cases, the existence of such a recti cation is proven indirectly, without an explicit construction of the mapping α. In this paper,...
We attempted to isolate ES cell lines using inner cell masses from high-quality cloned porcine blastocysts. After being seeded onto feeders, embryos had better (P < 0.05) attachment, outgrowth formation and primary colonization in both 2× and 3× aggregated cloned embryos (62.8, 42.6 and 12.8% vs. 76.2, 55.2 and 26.2%, respectively) compared to the non-aggregated group (41.6, 23.4 and 3.9%). Eff...
BACKGROUND/AIMS Pluripotent stem cells differentiating into cardiomyocyte-like cells in an appropriate cellular environment have attracted significant attention, given the potential use of such cells for regenerative medicine. However, the precise mechanisms of lineage specification of pluripotent stem cells are still largely to be explored. Identifying the role of various small synthetic pepti...
PURPOSE Equivalent Square (ES) enables the calculation of many radiation quantities for rectangular treatment fields, based only on measurements from square fields. While it is widely applied in radiotherapy, its accuracy, especially for extremely elongated fields, still leaves room for improvement. In this study, we introduce a novel explicit ES formula based on Weighted Power Mean (WPM) funct...
Kontrolliertes Einfrieren in den Temperaturbereich zwischen – 80 °C und – 196 °C erlaubt es Zellen, bei gleichzeitigem Erhalt ihrer Vitalität nach dem Auftauprozess, langfristig zu lagern. Durch die Verwendung von Antioxidantien sollte in der vorliegenden Arbeit eine Steigerung der Rekultivierbarkeit von mesenchymalen Stammzellen nach der Kryokonservierung erzielt werden. Der Zusatz von 100 μM ...
Es wurde gezeigt, daß die früher abgeleitete Gleichung für die Molverteilung von linearen Methylpolysiloxanen im Verlaufe der Äquilibrierungsreaktion für den Fall von beliebigen difunktionelle D-Einheiten enthaltenden Ausgangsstoffen verallgemeinert werden kann. Die allgemeine Lösung der Geschwindigkeitsgleichung konnte mit den experimentellen Befunden bestätigt werden. In einer früheren Arbeit...
: pulpotomy is an accepted treatment for the management of cariously exposed pulps in symptom free primary molars. the purpose of this study was to compare the clinical and radiological outcomes of three different single-visit vital pulp therapies including pulpotomy with electrosurgery (es), formocresol (fc) and ferric sulfate (fs) in cariously exposed primary molar teeth . materials & methods...
