    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.

    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.

    Notes: [Auszug] X-chromosome inactivation (XCI) ensures the equality of X-chromosome dosages in male and female mammals by silencing one X in the female. To achieve the mutually exclusive designation of active X (Xa) and inactive X (Xi), the process necessitates that two Xs communicate in trans through homologous ...

    Notes: [Auszug] The Tr2 orphan nuclear receptor can be SUMOylated, resulting in the replacement of coregulators recruited to the regulatory region of its endogenous target gene, Oct4. UnSUMOylated Tr2 activates Oct4, enhancing embryonal carcinoma-cell proliferation, and is localized to the promyelocytic leukemia ...

    Notes: [Auszug] Gene regulation in eukaryotes requires the coordinate interaction of chromatin-modulating proteins with specific transcription factors such as the androgen receptor. Gene activation and repression is specifically regulated by histone methylation status at distinct lysine residues. Here we show ...
