Early markers of breast cancer in nipple aspirate fluid
Nipple aspirate fluid (NAF) refers to the small amount of secretion that is found in breast ducts/lobules of most non-lactating women. This fluid can be collected repeatedly and non-invasively via the nipple using a modified breast pump, and therefore, it is considered to be a potential source for …

Growth of epitaxial nanoscale columnar copper indium diselinide thin films by introduction of sodium flouride during growth
The effect of NaF on the growth of CuInSe2 (CIS) epitaxial thin films by a hybrid sputtering and evaporation method was studied. Low levels of NaF deposition during interruptions of epitaxial growth reduced surface roughness. Larger amounts of NaF resulted in columnar epitaxial films with <112> …

Interaction between tin/flouride-containing solutions and artificially created dental pellicles on erosion prevetion in vitro
… METHODS: Phase I tested four solutions: SnCl2/NaF, NaF, SnCl2 and deionized water (DIW) (as negative control). Forty bovine enamel and dentin specimens 104 (4x4x2 mm3) were prepared and randomly distributed into 4 groups (n = 10). The specimens were incubated in clarified human saliva (CHS) for …
