    Properties of DLC Films Produced by Pulsed Laser Induced Arc Deposition (2005)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 475-479 (Jan. 2005), p. 3901-3904 
    Details

    Notizen: Diamond like carbon (DLC) films were prepared on Si wafer, using laser induced arc deposition (Laser arc) technique. Results of Raman Spectra analysis showed that the as-deposit films were amorphous, having obvious sp3 structure. Meanwhile, surface topography and micro-tribological properties were investigated by using Atomic Force Microscope and Nano-Scratch Tester. Influences of arc voltage, substrate bias voltage, target materials and substrate pre-treatment methods upon the film structures and film properties were studied

    Regional and seasonal variations in facial sebum secretions: a proposal for the definition of combination skin type (2005)
    Oxford, UK : Munksgaard International Publishers
    Skin research and technology 11 (2005), S. 0

    Notizen: Background/aims: Facial sebum secretions are known to change under various circumstances. Facial skin types have been categorized as oily, normal, dry, and combination types. However, these have been evaluated subjectively by individuals to date, and no objective accepted standard measurement method exists. The combination skin type is most common, but its definition is vaguer than the definitions of the other skin types.Methods: We measured facial sebum secretions with Sebumeter®. Sebum secretions were measured at five sites of the face seasonally for a year, in the same volunteers. Using the data obtained we developed a set of rules to define the combination skin type.Results: Regional differences in sebum secretion were confirmed. Sebum secretions on forehead, nose, and chin were higher than on both cheeks. Summer was found to be the highest sebum-secreting season, and seasonal variations were found in the T- and U-zones. A mismatch of skin type in the T- and U-zones in more than two seasons appears to be close to subjective ratings of what is described as the ‘combination’ skin type.Conclusion: We showed that the face shows definitive regional and seasonal variations in sebum secretion. To define the combination skin type, seasonal variations in sebum secretion should be considered in addition to regional variations.

    Abscisic acid activates acid invertases in developing grape berry (2005)
    Oxford, UK; Malden, USA : Munksgaard International Publishers
    Physiologia plantarum 125 (2005), S. 0 
    Details
    ISSN: 1399-3054

    Thema: Biologie
    Notizen: Acid invertases play a key role in sugar metabolism, and the plant hormone abscisic acid (ABA) enhances sugar accumulation in crop sink organs, but information about the relationship between ABA and acid invertases has been limited. The present experiments were done with both in vivo pre-incubation of the grape (Vitis vinifera × V. labrusca L.) berry tissues in ABA-containing medium and in vivo infiltration of ABA into the intact berries. The results show that ABA activates both the soluble and cell wall-bound acid invertases during fruit development by enhancing their activities and amounts as assessed by immunoblotting or enzyme-linked immunosorbent assay. This activation was pH, time course and ABA dose dependent. The serine/threonine protein kinase inhibitors K252a, staurosporine and H7 and acid phosphatase increased the activation of ABA-induced acid invertase, but the tyrosine protein kinase inhibitor quercetin strongly suppressed the ABA-induced effects, suggesting that a complex reversible protein phosphorylation is involved in the ABA-induced activation of acid invertases. The effects of the protein kinase inhibitors were dependent on the in vivo state of the tissues but independent of the expression of acid invertases. Two ABA analogues, (–)-ABA and trans-ABA, had no effect on acid invertases, showing that the ABA-induced activation of acid invertases is specific to the physiologically active form of ABA. These data suggest that ABA may be involved in fruit development by activating acid invertases.
