The patient and her physician may be concerned about potential harm to the fetus from radiation exposure. In reality, however, the risks to the developing fetus are quite small. The accepted cumulative dose of ionizing radiation(More)
A line of transgenic mice containing the simian virus 40 (SV40) large tumor antigen gene under the control of the viral enhancer-promoter expressed this viral protein in the brains of these mice within the first 2 weeks after birth. Multiple foci of anaplastic cells formed in the choroid plexuses of these mice at 36 to 41 days after birth, and normal tissue(More)
While theoretical models predict a decrease in the cost of capital from depositary receipt offerings, the economic benefits of this liberalization have been difficult to quantify. Using a sample of 126 firms from 32 countries and a size and country matched control sample, we document a statistically and economically significant decline in returns of 42(More)

The c-myc oncogene codes for a DNA binding protein that appears to play an important role in the regulation of cell growth. c-myc gene amplification has been documented to occur in both hematopoietic and solid neoplasms and often indicates more biologically aggressive tumors. Southern hybridization analysis was performed on high-molecular-weight DNA(More)
A prospective study of surgical wound infections (SWI) in hip prosthesis surgery and total hip and knee replacements at two community hospitals with common surgical staffs was begun in May 1982. The rates of SWI during the first 7 months for four orthopedic surgeons were 9% (3/32) for hip prosthesis surgery and 16.7% (3/18) for total hip and knee(More)
