DAF-FM DA is widely used as a live staining compound to show the presence of nitric oxide (NO) in cells. Applying this stain to live zebrafish embryos is known to indicate early centers of bone formation, but the precise (cellular) location of the signal has hitherto not been revealed. Using sections of zebrafish embryos live-stained with DAF-FM DA, we could confirm that the fluorescent signals were predominantly located in areas of ongoing bone formation.

Both the phase and amplitude of the effective single-qubit rotation depend on the electric field, which can be localized to each zone. We demonstrate this interaction on a single ion using both laser-based and magnetic-field gradients in a surface-electrode ion trap, and measure the localization of the electric field.

The ion-ion interaction is enhanced via a room-temperature electrically floating metallic wire which connects two surface traps. Tuning the motion of both ions into resonance, we show flow of energy with a coupling rate of 11 Hz.

- Superoxide dismutase 3 (SOD3) is an important protein that converts harmful superoxide into hydrogen peroxide, and research on zebrafish reveals two versions of this protein (Sod3a and Sod3b) with distinct functions.
- Both Sod3a and Sod3b exhibit SOD activity, but only Sod3b can bind to heparin, and they are expressed in different organs throughout zebrafish development and in adults.
- Further studies comparing bone from normal mice to SOD3 mice indicate that SOD3 is crucial for bone health, as the SOD3 mice displayed weaker and less mineralized bones.
Protein and amino acid (AA) availability of three protein meals of expected different quality were evaluated in young growing and adult mink. Lamb meal (LM), poultry meal (PM) or fishmeal (FM) were used as main protein sources in three extruded diets investigated by determining apparent total tract digestibility (ATTD) and nitrogen balance in 12 growing mink males aged 8-11 weeks in a Latin square design. In adult mink, ATTD of the diets was determined.
