    Notes:
    The expression of SPARC (secreted protein acidic and rich in cysteine/osteonectin/BM-40) is elevated in endothelial cells participating in angiogenesis in vitro and in vivo. SPARC acts on endothelial cells to elicit changes in cell shape and to inhibit cell cycle progression. In addition, SPARC binds to and diminishes the mitotic activity of vascular endothelial growth factor. To determine the effect(s) of SPARC on angiogenic responses in vivo, we implanted polyvinyl alcohol sponges subcutaneously into wild-type and SPARC-null mice. On days 12 and 20 following implantation, SPARC-null mice showed increased cellular invasion of the sponges in comparison to wild-type mice. Areas of the sponge with the highest cell density exhibited the highest numbers of vascular profiles in both wild-type and SPARC-null animals. The endothelial component of the vessels was substantiated by immunoreactivity with three different markers specific for endothelial cells. Although sponges from SPARC-null relative to wild-type mice were populated by significantly more cells and blood vessels, an increase in the ratio of vascular to nonvascular cells was not apparent. No differences in the percentage of proliferating cells within the sponge were detected between wild-type and SPARC-null sections. However, elevated levels of vascular endothelial growth factor were associated with sponges from SPARC-null versus wild-type mice. An increase in vascular endothelial growth factor production was also observed in SPARC-null primary dermal fibroblasts relative to those of wild-type cells. In conclusion, we have shown that the fibrovascular invasion of polyvinyl alcohol sponges is enhanced in mice lacking SPARC, and we propose that increased levels of vascular endothelial growth factor account, at least in part, for this response.

    Notes:
    The impaired wound healing associated with aging may reflect inadequate secretion or delivery of cytokines. Transforming growth factor-β1 is a mitogenic polypeptide with beneficial effects on wound healing. In the present study we questioned whether topical administration of transforming growth factor-β1 could improve the wound healing process in aged rats in vivo. Wound repair (from 1 to 14 days) was analyzed in full-thickness incisional wounds from 2-year-old rats with or without a single topical application of transforming growth factor-β1 (1 µg/wound) at the time of wounding. Identical wounds from 3-month-old, untreated rats served as controls. Histologic analysis showed a marked delay in several aspects of wound repair in the aged rats in comparison with that noted in the younger animals. Immunostaining of the wounds for proliferating cell nuclear antigen showed a reduction in the number of cycling fibroblasts in old rats. In addition, the number of capillaries per unit area of the wound as determined by a stain for Griffonin (Bandeiraea) simplicifolia lectin, and the number of inflammatory cells as identified by an antibody specific for macrophages, were also reduced in the wound area in old rats. Treatment with transforming growth factor-β1 resulted in marked enhancement of the following parameters: cell proliferation, inflammatory cell and fibroblast influx, wound closure, and angiogenesis. As seen with in situ hybridization, a similar temporal pattern of expression of messenger RNAs corresponding to type I procollagen and Secreted Protein, Acidic and Rich in Cysteine (osteonectin), known to be prevalent in healing wounds, was observed in both young and aged rats. However, the levels of mRNA corresponding to these secreted proteins appeared to be reduced in wound tissue from aged rats. Treatment with transforming growth factor-β1 subsequently resulted in an increase in the expression of both type I procollagen and Secreted Protein, Acidic and Rich in Cysteine mRNA in the wound tissue from aged rats. In summary, a single topical application of transforming growth factor-β1 to the wounds of aged rats at the time of wounding was associated with a healing response that, in all the parameters of wound repair examined, was similar to that of young rats. Topical transforming growth factor-β1 might therefore be beneficial in the treatment of dermal wounds in the aged.

    Notes:
    Results are presented regarding the sintering mechanisms of barium hexaferrite (BaFe12O19) and modification thereof via secondary phase additions. Additional studies are presented concerning the effect of additives and microstructural development on the resultant microwave frequency magnetic and dielectric loss properties. The increasing demands on materials for microwave application has required development of barium hexaferrites to achieve fine grain size (i.e., ≤1 μm), a high degree of c axis alignment, high density and a minimum in dielectric loss. To accomplish such a task one area of interest is that of incorporating secondary phases. Additions of SiO2, Al2O3 and CaCO3 are examined in terms of grain size, magnetic, and dielectric loss properties. Thermal analysis methods revealed a redox reaction associated with the sintering process in barium hexaferrite. The use of yttrium iron garnet (Y6Fe10O24) indicated an enhanced densification behavior in comparison to undoped barium hexaferrite which was associated to a decreased redox reaction temperature. The inclusion of the SiO2, Al2O3, and CaCO3 additions were seen to inhibit the redox reaction as measured via thermal analysis while liquid phase sintering occurred. © 1996 American Institute of Physics.

    Notes:
    Three types of commercial zinc oxide varistor materials were examined using admittance spectroscopy between 30 and 350 K. Maxima in the ac conductance at frequencies from 1 to 100 kHz are observed. The maxima are interpreted as arising from electron traps located within the depletion regions of double Schottky barriers at ZnO-ZnO grain boundaries. Two traps are observed in each material and are likely to be from common origin. The trap energies are found to be 0.17 and 0.33 eV below the conduction-band edge. The traps are likely to be associated with native defects in ZnO and may influence device characteristics such as voltage overshoot.

    Notes:
    The anterior cingulate cortex presumptively regulates blood pressure reactions to behavioral stressors. There is little evidence in humans, however, that stressor-evoked changes in blood pressure correlate with concurrent changes in anterior cingulate activity. Using fMRI, we tested whether changes in mean arterial blood pressure correlate with ongoing changes in blood oxygen level dependent (BOLD) activation in 9 women and 11 men who completed a stressful Stroop color-word interference task. Higher mean arterial pressure during the Stroop task correlated with greater BOLD activation in two regions of the cingulate cortex (perigenual and mid-anterior) and in other networked brain regions, including the insula, thalamus, and periaqueductal gray. These results support the hypothesis that the anterior cingulate cortex regulates blood pressure reactions to behavioral stressors in humans.
