Data suggest that angiogenesis occurs at the periphery of the HFA. The DZ-predominant expression of Ang2 may be explained, in part, by the parallel pattern of FGF-2 expression.

Na-2-mica of the ideal composition of Na 2 Mg 6 Al 2 Si 6 O 20 F 4 ?xH 2 O was prepared from a mixture of NaF, magnesium nitrate, SiO 2 and calcined kaolinite (the latter serving as a cost-effective aluminosilicate source) at 800 uC and was found to excel in Sr removal from solutions at room temperature. This mica was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and 27 Al and 29 Si magic angle spinning nuclear magnetic resonance (MAS-NMR) spectroscopy. Fundamental studies of nNa z AM nz (M nz ~Sr 2z , Ca 2z , Li z , K z and Cs z ) equilibria revealed a high selectivity and large capacity for Sr 2z ion uptake. A relatively low-temperature heat treatment (200 uC) of the Sr-exchanged mica resulted in collapse of the hydrated interlayer spacings of the mica, which will be useful to immobilize strontium in the stable unhydrated phase. This selective Sr-ion exchanger is expected to be useful for 90 Sr removal and its immobilization.
