    Notes: 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

    Notes: Sixty-two serous and mucinous ovarian tumors, an admixture of benign, borderline and malignant neoplasms, were immunostained for proliferating cell nuclear antigen (PCNA), with the monoclonal antibody PC10. The PC10 index, the proportion of cells showing nuclear positive staining, was calculated in each case. All the tumors showed positive immunoreactivity for PCNA. There was no overlap of PC10 counts between benign, borderline and malignant serous tumors but within the mucinous group of neoplasms there was considerable overlap between the counts for borderline and malignant tumors. There was no relationship between the PC10 index and the surgical stage of the malignant neoplasms and the index could not be correlated with patient death. Staining for PCNA does not, therefore, appear to be of any prognostic value in ovarian adenocarcinomas.

    Notes: Metalorganic chemical vapor deposition of PbTiO3 using Pb (tmhd)2, Ti(OC3H7)4, and N2O via thermal pyrolysis at relatively low temperature (∼500 °C) was performed in order to produce PbTiO3 insulator gates with high quality PbTiO3/p-Si interfaces. Raman spectroscopy showed the several optical phonon modes of the PbTiO3/p-Si structure. The stoichiometry of the PbTiO3 films was observed by Auger electron spectroscopy. Room-temperature current-voltage and capacitance-voltage measurements clearly revealed metal-insulator-semiconductor behavior for the samples with a PbTiO3 insulator gate, and the interface state densities at the PbTiO3/p-Si were approximately 1011 eV−1 cm−2 at the middle of the Si energy gap.

    Notes: Background. Diagnosis of paucibacillary leprosy is often difficult. A method that could confirm the diagnosis is the polymerase chain reaction (PCR) of M. leprae DNA. This reaction was applied to biopsied tissues of leprotic patients to determine the suitability and sensitivity of the reaction. Methods. Biopsy samples were taken from previously untreated patients with multibacillary (5 patients) and paucibacillary (3 patients) leprosy, fixed in formalin, and embedded in paraffin, DNA was extracted from paraffin blocks and PCR applied. The sensitivity of the PCR method was tested by using the serially diluted DNA sample as the template. Results. All eight patients showed a positive PCR for M. leprae DNA. The sensitivity was such that a single organism of M. leprae, as counted by staining of the acid-fast bacilli was identified by the PCR. Conclusions. The PCR method is simple, sensitive, specific, and does not require the use of radioisotopes. It can be applied to the unequivocal diagnosis of paucibacillary leprosy which is difficult by other means. The diagnosis can be obtained within 10 hours.Int J Dermatol 1993; 32:710–713

    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

    Notes: 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.

    Effect of dietary vitamin C and ammonia concentration on the cellular defense response of Macrobrachium nipponense (2005)

    Notes: This study examined the effects of dietary vitamin C and ammonia concentration on the cellular defense response of Macrobrachium nipponese. The response of the cellular defense was determined by monitoring changes in reactive oxygen intermediates in hemocytes, superoxide dismutase activity, catalase activity, glutathione peroxidase activity, glutathione reductase and glutathione transferase activity in muscle. The results showed that prawns fed the basal diet had a significant increase in reactive oxygen intermediates in response to exposure to ammonia-N. When dietary vitamin C was added to the feed, there was a significant decrease in reactive oxygen intermediates in response to exposure to ammonia-N. Total superoxide dismutase and glutathione peroxidase activity of prawns fed the basal diet decreased as ammonia-N increased. This decrease in activity was significantly less pronounced in prawns that were fed the dietary vitamin C supplement. In prawns that were fed the dietary vitamin C supplement there was no significant variation in catalase reductase or gluxathione reductase activity in response to variations in ammonia-N concentration. The glutathione transference activity increased at a low concentration of ammonia-N in prawns that were fed the dietary vitamin C supplement, but there was no significant variation in the prawns fed the basal diet. Overall the results indicate that dietary vitamin C supplements enhance the capacity of M. nipponese to respond to elevations in ammonia-N. This response involved several biochemical reactions known to be involved in cellular defense.

    Regional and seasonal variations in facial sebum secretions: a proposal for the definition of combination skin type (2005)

    Notes: 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.

    Notes: Purpose - Cyber-brands are regularly valued but, to date, there has been no reported research designed to understand the derivation of cyber brands' equity, so that attempts can be made to increase their brands' equity efficiently. This research aims to address the issue. Design/methodology/approach - To measure the strength of cyber brands, prior off-line research is replicated, taking a customer focus to identify determinate variables. These customer-focused variables are tested against cyber consumers' stated satisfaction and site-visit intention behavior, using regression analysis. Findings - The results satisfactorily justify the suggested model, which has a predictive power ranging from 62 to 72 per cent. Practical implications - The study shows that practitioners intent on raising the power of their cyber brand can be guided by the same model as used off-line. Originality/value - The major theoretical contribution of the study is to show that there is little difference between measuring and increasing brand power on or off-line.
