The ability of paditaxel, one of the most active chemotherapeutic agents against breast cancer, to induce programmed cell death in hormone-independent MDA-MB-468 human breast cancer cells was assessed. Treatment of MDAMB-468 cells led to growth inhibition, high-molecular-weight and oligonucleosomal DNA fragmentation, and apoptosis-associated morphological changes after either 3or 24-h exposure ...

This chapter addresses an open problem in visual motion analysis, the estimation of image motion in the vicinity of occlusion boundaries. With a Bayesian formulation, local image motion is explained in terms of multiple, competing, nonlinear models, including models for smooth (translational) motion and for motion boundaries. The generative model for motion boundaries explicitly encodes the ori...

Using unique data on firm origins, early composition and multiple stages of performance measures, we provide evidence that if there are significant differences in the organizational capability to find valuable resources, then empirical tests of organizational economics alone with yield spurious results. Similarly, if determining the optimal arrangements for governance and transactions significa...

Twenty-five years ago, as the “War on Cancer” began, there was hope and anticipation that the mortality rates for common forms of cancer might be greatly reduced by the year 2000. Although this goal has not been attained, a primary result of the increased funding for cancer research during the past 25 years has been an immense increase in knowledge of the mechanisms whereby normal cells and tis...

There ¡sa range of levels of glucocorticoid receptor numbers seen in the various subclasses of acute lymphatic leukemia (ALL). This variability cannot be explained by the known cor relation between active cell proliferation and an increase in the number of receptors, since the tumors with the highest growth fraction (i.e., Burkitt's lymphoma and T-cell leukemia) tend to have lower average rece...

Research on gender and video game playing has long been interested in the question of why females play fewer video games and play video games less frequently than males do. The present study examines the immediate impacts of a negative gender stereotype on females' motivation for and performance in playing a racing video game. Exposure to a negative gender stereotype about video game playing wa...

The present study examines the effects of humor and relevance on memory for factual statements. Participants (N=48) read pairs of statements. Each pair included a fact that was always nonhumorous, and a joke that was either humorous or nonhumorous and relevant or irrelevant to its paired fact. In a later memory test, recall of pairs (i.e. both fact and joke) was better when the joke was humorou...

Hepatocyte growth factor/scatter factor (HGF/SF) is a stromallv de rived modulator of epithelial cell proliferation and morphology. To better assess the potential role of HGF/SF in tumor progression we sought to identify factors and biological conditions which regulate its expression. We show that several adult human primary fibroblast cultures from breast and prostate produce HGF/SF. HGF expre...

In short-term serial recall, similar-sounding items are remembered less well than items that do not sound alike. This phonological similarity effect has been observed with lists composed only of similar items, and also with lists that mix together similar and dissimilar items. An additional consistent finding with mixed lists has been an effect we refer to as “dissimilar immunity”. Dissimilar i...
