Food Authentication Goes Green: Method Optimization for Origin Discrimination of Apples Using Apple Juice and ICP-MS.

Apples are among the most important fruits worldwide and the most consumed fruit in Germany. Due to higher energy and personnel costs, domestic apples are more expensive and thus offer an incentive for mixing with foreign goods. Moreover, imported apples have a higher carbon footprint, which is an obstacle regarding sales in times of climate change.

The influence of radiation-induced collagen chain fragmentation, crosslinking, and sequential irradiation on the high-cycle fatigue life of human cortical bone.

Both high-cycle fatigue life and fatigue crack propagation resistance of human cortical bone allograft are radiation dose-dependent between 0 and 25 kGy such that higher doses exhibit progressively shorter lifetimes. Recently, we have shown that collagen chain fragmentation and stable crosslink accumulation may contribute to the radiation dose-dependent loss in fatigue crack propagation resistance of human cortical bone. To our knowledge, the influence of these mechanisms on high-cycle fatigue life of cortical bone have not been established.

Caloric Restriction Diet Attenuates Systemic Bone Fragility after Radiotherapy.

Bone fragility is a well-documented long-term side effect of radiotherapy, which currently has no preventative treatments. In this study, we applied a caloric restriction (CR) diet to attenuate both local and systemic bone loss after irradiation (RTx) in an established female Balb/c mouse model (4 consecutive daily doses of 5 Gy to the right hindlimb only). CR mice were tapered down to a 30% reduced calorie diet (RTx/CR) one week before irradiation, while regular diet (RD) mice received food ad libitum (RTx/RD).
