Alterations in genomic content and changes in gene expression levels are central characteristics of tumors and pivotal to the tumorigenic process. We analyzed 23 non-small cell lung cancer (NSCLC) tumors by array comparative genomic hybridization (array CGH). Aberrant regions identified included well-characterized chromosomal aberrations such as(More)
The NCI-60 panel [1], which consists of 60 human cancer cell lines derived from 9 different tissues of origin, has been characterized by a wide variety of methods at the DNA, RNA, protein, and functional levels [see e.g., 2-6]. The cells have also been profiled by exposure to more than 100,000 different chemical agents. Recent studies have shown that(More)
Higher interannual precipitation variability is predicted for Southern California’s shrub-dominated systems, promoting soil moisture variation and changing community composition. We asked if soil microbial responses to rainfall regime will depend on litter inputs; showing direct effects of altered precipitation through soil moisture and indirect effects(More)
PURPOSE Paralytic lagophthalmos can cause exposure keratopathy. Current treatments have difficulties: extrusion, migration, allergic reaction, anatomical disruption, and technically difficult surgeries. The goal of this study was to design, create, and assess a new method for eyelid closure using magnets. METHODS This experimental study is approved by(More)
As a biomedical engineer, one seldom gets the opportunity to help patients return to health in areas in which the magnitude of the need, or the adoption of the approach, is unproven. Returning to my alma mater, Cornell University in Ithaca, New York, in late 2004, I was given the opportunity to coordinate the master of engineering program in biomedical(More)
This article evaluates changes in the use of drug services and the corresponding costs when the conventional fee-for-service system for reimbursement of pharmacists under medicaid is replaced by a capitation system. The fee-for-service system usually covers ingredient costs plus a fixed professional dispensing fee. The capitation system provided a cash(More)
