Epidemiological surveys of occurrence of human neoplastic disease as well as in-vitro and in-vivo experimental models indicate that tumorigenesis is a multistep process involving independent genetic events.1-3 In particular, studies with retroviruses

A ‘‘nonisolated‐sensor’’ solid polystyrene calorimeter was constructed to test the role of thermal diffusion in limiting the length of irradiation time during which temperature measurements with nonisolated sensors could be made sufficientl

An apparatus for precision calibration of ion chambers in the x‐ray region from 16 to 320 kV is described. The development of a fast‐acting shutter with ‘‘opening’’ and ‘‘closing’’ times of less than 3‐ms eliminates the requirem

Neutron fluxes and dose rates in and near the 18-MV x-ray beam of a Therac-20 accelerator were determined with measured activities from the nuclear reactions 31P(n, rho)31Si (fast neutrons) and 31P(n, gamma)32P (thermal neutrons), published cross sec

A ‘‘nonisolated‐sensor’’ solid polystyrene calorimeter is described which permits absorbed dose measurements with precision of less than 0.3% (standard error of the mean). The accuracy for obtaining absolute absorbed dose was estimated by c

Two multichannel instruments for fluorescent X-ray spectroscopy are described in detail, the Applied Research Laboratories' X-ray Research Quantometer and X-ray Industrial Quantometer. Each instrument uses a 60 kV, full-wave, filtered supply with a M

We have studied the kinetics of suppression of tyrosinase activity and tumorigenicity in unsynchronized B16 mouse melanoma cells (clone B/sub 5/59) exposed to 5-bromodeoxyuridine (BrdU, 3 ..mu..g/ml) for one or two cell divisions, then cultured in Br

C3H/10T1/2 cells were infected with a retroviral vector expressing a mouse c-myc oncogene and a drug-selection marker. The resulting cells, morphologically indistinguishable from C3H/10T1/2, displayed a greatly enhanced sensitivity to neoplastic tran

The c-myc oncogene has been implicated in deregulation of cell growth in neoplastic cells and response to "competence-inducing" growth factors in normal cells. In the latter case, expression of c-myc has been shown to be associated with the transitio
