BACKGROUND AND METHODS
The role of colonoscopy in screening for colorectal cancer is uncertain. At 13 Veterans Affairs Medical Centers, we performed colonoscopy to determine the prevalence and… (More)
Native microtubules prepared from extruded and dissociated axoplasm have been observed to transport organelles and vesicles unidirectionally in fresh preparations and more slowly and bidirectionally… (More)
Our research explored factors that impacted the use of wikis as a tool to support the dissemination of knowledge within an enterprise. Although we primarily talked to a population of wiki… (More)
Cytoplasmic dynein is one of the major motor proteins involved in intracellular transport. It is a protein complex consisting of four subunit classes: heavy chains, intermediate chains (ICs), light… (More)
Epidemiological and experimental studies have suggested an enhancement of asbestos-induced bronchogenic carcinoma by cigarette smoke. Further, our recent experimental and epidemiological studies have… (More)
Effects of 50 Hz electromagnetic fields on phagocytosis and free radical production were examined in mouse bone marrow-derived macrophages. Macrophages were in vitro exposed to electromagnetic fields… (More)

Nineteen specimens from primary human malignant mesotheliomas obtained from 19 patients were screened for activating point mutations in the oncogenes N-ras and CDK4 by combined RFLP-PCR/SSCP… (More)
Eighteen human congenital melanocytic naevi (CMN) from 17 patients were screened for activating point mutations in the oncogenes N-ras and CDK4 and for sequence variants in the MC1R gene by combined… (More)
Studies of organelle movement in axoplasm extruded from the squid giant axon have led to the basic discoveries of microtubule-dependent organelle motility and the characterization of the… (More)
