Electron spin resonance of Eu 2 + in the Eu doped clathrate Ba 6Ge 25

We report electron spin resonance (ESR) investigations of the clathrate compound Ba 6-x Eu xGe 25 (x=0.03–0.4) which exhibits a temperature induced, two-step reconstructive structure transformation at temperatures between 185 K and 223 K. The linewidth of the Eu 2+ ESR proves to be sensitive to the transformation. Another anomaly in the temperature dependence of the linewidth is found near T=60 K which points towards another possible structural transition. Both anomalies seen in the ESR linewidth are not sensitive to the Eu content in contrast to the strong Eu-concentration dependence of transport properties.

Effect of fracture on bone turnover markers: A longitudinal study comparing marker levels before and after injury in 113 elderly women

In this longitudinal, prospective, and population-based study (n = 1044), seven BTMs were assessed before and after trauma in 113 elderly women (85 with fractures). Markers were not altered in the immediate postfracture period but were clearly elevated during fracture repair. Recent fracture should thus be taken into account when markers are used in clinical practice
