Fluorescent Studies

Embryonic development is a dynamic event and is best studied in live animals in real time. Much of our knowledge of the early events of embryogenesis, however, comes from immunofluourescent analysis of fixed embryos. While these studies provide an enormous amount of information about the organization of different structures during development, they can give only a static glimpse of a very dynamic event. More recently real-time fluorescent studies of living embryos have become much more routine and have given new insights to how different structures and organelles (chromosomes, centrosomes, cytoskeleton, etc.) are coordinately regulated. This is in large part due to the development of commercially available fluorescent probes, GFP technology, and newly developed sensitive fluorescent microscopes. For example, live confocal fluorescent analysis proved essential in determining the primary defect in mutations that disrupt early nuclear divisions in Drosophila melanogaster. For organisms in which GPF transgenics is not available, fluorescent probes that label DNA, microtubules, and actin are available for microinjection.

SummaryLupus anticoagulants (LA) and anticardiolipin antibodies have been strongly associated with recurrent abortion and fetal death. Because steroids have been reported to improve the fetal outcome of LA associated pregnancies, presumably by decreasing the levels of LA, it becomes desirable to have a simple and reliable test to monitor the levels of the putative antibody. To this effect, we assessed the capacity of the following coagulation tests to detect the presence of LA in serial dilutions of patient plasma with pooled normal plasma: kaolin clotting time (KCT), tissue thromboplastin inhibition test (TTIT), dilute Russell Viper venom time (DRVVT) and activated partial thromboplastin time with standard and high concentrations of phospholipids (SC and HCAPTT). All samples were also evaluated for the presence of anticardiolipin antibodies with an ELISA. The KCT was able to detect LA at a much greater dilution in normal plasma than any of the other clotting assays. The ELISA was comparable to KCT in its ability to detect high dilutions of LA.

This paper examines the relative sensitivity of CEO compensation of both acquiring and acquired firms in the top 30 U.S. largest corporate acquisitions in each year for the period of 2003 to 2012. We find that total compensation and bonus granted to executive compensation for acquired companies, not acquiring companies, are significantly related to the amount of acquisition deal even after the size and firm performance are controlled for. Both acquiring and acquired CEOs are found to make the significantly higher compensation than the matched sample firms in the same industry and calendar year. We also find that executives with higher managerial power, as measured by a lower salary-based compensation mix, prior to a corporate acquisition are more likely to receive a higher executive pay in the year of acquisition. The association between executive compensation and managerial power seems to be stronger for acquired firms than for acquiring firms in corporate acquisition. Overall, our findings suggest that corporate acquisition has higher impacts on executive compensation for acquired firm CEOs than for acquiring firm CEOs.
