From controlled to committed.

Most of us agree that people are our most important resource. Yet we spend a minimal amount of time learning more about human behavior, communication, and how our attitudes and behavior impact employee performance. Instead we rely on traditional methods of negative reinforcement in an attempt to control our areas of responsibility. While these methods can render some short-term success, managers and organizations that succeed during these times of change and fierce competition will be those that take the time to understand and capture the power of a committed workforce. The committed workforce is energized, not simply compliant, as a result of having basic human needs for achievement satisfied, belonging to a group, and receiving recognition for its contributions. Committed workers typically describe the manager as one who has the ability to give them a great degree of control over their area of influence. We all know that we don't change our leadership style like we change clothes. Old habits die hard. it takes a personal commitment and lots of practice to rid outselves of habits and behavior that no longer serve our departments and facilities. This commitment, however, is crucial to survival. As managers, we must cope with increasing ambiguity and uncertainty in the workplace. To survive these challenges, we must improve our interpersonal skills and ability to successfully bring out the best in others. I believe that success will continue for managers who not only increase their knowledge and technical ability, but who also inspire their workers to move forward with a collective sense of enthusiasm and purpose.

Growth factor profiles in breast cyst fluid identify women with increased breast cancer risk.

Gross cystic disease and breast cancer are hormonally induced diseases that may share a common biochemical environment conducive to abnormal proliferative responses. Breast cyst fluid samples were analyzed for specific growth factors and levels were compared with breast cancer risk. Growth factor profiles identified both women at increased breast cancer risk and subgroups of women with distinct clinical manifestations of gross cystic disease. Women at increased risk for breast cancer demonstrated in their breast cyst fluid lower levels of platelet-derived growth factor and transforming growth factor (TGF)-beta, compared to women at lower risk. The presence of multiple cysts was associated with increased mitogenic activity, increased epidermal growth factor (EGF) and TGF-beta breast cyst fluid levels, and recurrent cysts were associated with higher levels of EGF. Unique growth factor profiles were associated with each risk group or clinical state, suggesting that distinct proliferative environments, associated with different clinical outcomes, are present in the breast tissue of women with gross cystic disease.

[Comparative study of different imbedding materials for light histology of decalcified human teeth].

Four embedding media were compared: paraffin, the mixing "paraplast-piccolyte", Technovit 7100, and JB 4. Each material embedding technic is described. Comparison criteria are: easiness in the technic and method, cutting and trimming qualities, staining, anatomy connections conservation. Results are compacted in a diagram and illustrated by microphotographs. Methacrylate resins, and particularly JB 4, gave us best results.
