The subtractive hybridization, namely the hybridization for screening of the group-specific (differentially expressing) nucleic acids species from various tissues and cell lines, is a very important tool for the studies of tumor molecular biology and the tumor suppressor genes.展开更多

Modes with 40 and near 70 days frequency associated with swings in longitude of the South Pacific and South Atlantic Ocean heights were identified. Their extreme values were related to drought and to high anomalous precipitation associated to floods in South East South America (SESA). These modes were independent of other sources of variability of the Southern Hemisphere atmosphere, namely MJO (Madden-Julian Oscillation), ENSO (El Nino Southern Oscillation) and AAO (Antarctic Oscillation). Mode one, which in its positive phase has a circulation similar to the mean winter, has a trend that explains part of the winter warming observed since 1980’s in Central and Eastern Argentina. Variance was calculated for the intra-annual variability, the one associated to the inter-annual variability including trends and jumps, and that of the annual cycle. The partition of the total variance was roughly 70%, 10% and 20% respectively. This partition implies that predictability of the regional climate is more critically dependent on the predictability of the intra-annual variability than of the inter-annual variability.展开更多

It is shown that this immobilization approach isan efficient one for lipase. The activity of the immobilized lipase can rerch to300 - 450 U/g (dry weight). It exhibits good temperature stability, can retain88% activity after being incubated at 70℃ for 2 h. Special effects will be expected from our immobilized lipase in its applications in organic media due tothe nature Of the support.展开更多
