Polyhydroxybutyrate (PHB) is a biomaterial with potential for applications in biomedical and tissue engineering; however, its brittle nature and high crystallinity limit its potential. Blending PHB with a variety of PEGs produced natural-synthetic composite films composed of FDA-approved polymers with significant reductions in crystallinity, from 7...

Near infrared spectroscopy (NIRS) provides a non-invasive method for the continuous monitoring of changes in tissue oxygenation and blood volume during aerobic exercise. During incremental exercise in adult subjects there was a positive correlation between lactate threshold (measured by blood sampling) and changes in the rate of muscle deoxygenatio...

Untersucht wurde die physiol. Reaktion auf Zugarbeit von 7 Ochsen der Rasse Hinterwaelder in Hohenheim und von 6 Zebuochsen in der Republik Niger. Ochsen zogen einen Bremsschlitten mit 5 ansteigenden Laststufen. Keine Reaktion zeigten die Konz. von Creatinin, Mg und Ca sowie die Aktivitaeten der Enzyme AP, CPK, GPT, GOT und LDH. Die Herzfrequenz (H...
