Direct data distribution from low-Earth orbit

Autor: G. Fujikawa, J. M. Budinger, R.L. Spence, N.T. Nguyen, Robert R. Romanofsky, R.R. Kunath

Publikováno v: ICC (2)

NASA Lewis Research Center (LeRC) is developing the space and ground segment technologies necessary to demonstrate a direct data distribution (D/sup 3/) system for use in space-to-ground communication links from spacecraft in low-Earth orbit (LEG) to

Nursing care protocols for the kidney/islet cell transplant recipient

Autor: J M, Budinger, S S, Donnelly

Publikováno v: ANNA journal. 21(2)

Statistically 3 out of 4 patients with diabetes mellitus die from the secondary effects of the disease. Approximately 30%-40% of patients with end stage renal disease (ESRD) have diabetes. Simultaneous kidney/islet cell transplantation offers an inno

Publikováno v: Conference on Advanced SEI Technologies.

The development of a high data-rate communications electronic subsystem for future application in free-space, direct-detection laser communications is described. The dual channel subsystem uses quaternary pulse position modulation (QPPM) and operates

Effects of cimetidine, nitrite, cimetidine plus nitrite, and nitrosocimetidine on tumors in mice following transplacental plus chronic lifetime exposure

Autor: L M, Anderson, A, Giner-Sorolla, I M, Haller, J M, Budinger

Publikováno v: Cancer research. 45(8)

Cimetidine (CM), a drug widely prescribed for ulcers, readily undergoes nitrosation to form nitrosocimetidine (NCM), a genotoxic agent. In a test of the chronic effects of NCM in mice, (C57BL/6 X BALB/c)F1 mice were exposed chronically to NCM (113 or

Lung tumorigenesis in mice after chronic exposure in early life to a low dose of dimethylnitrosamine

Autor: L M, Anderson, L J, Priest, J M, Budinger

Publikováno v: Journal of the National Cancer Institute. 62(6)

Strain A female mice were exposed to 10 ppb dimethylnitrosamine (DMN) in their drinking water for 4 weeks before mating. Treatment was continued through pregnancy and lactation and after weaning until the progeny were 22 weeks old. The incidence of p

Increased incidence of mammary tumors in rats after direct or transplacental exposure to 3-hydroxyxanthine

Autor: L M, Anderson, M N, Teller, J M, Budinger, G B, Brown

Publikováno v: Journal of the National Cancer Institute. 61(6)

Rats were exposed directly or transplacentally to the carcinogenic purine N-oxide 3-hydroxyxanthine (3-OH-X). Among female noninbred Wistar rats given 3-OH-X sc, beginning at suckling or weaning ages, there was a significantly greater proportion of m

Effects of polychlorinated biphenyls on lung and liver tumors initiated in suckling mice by N-nitrosodimethylamine

Autor: L M, Anderson, K, van Havere, J M, Budinger

Publikováno v: Journal of the National Cancer Institute. 71(1)

A mixture of polychlorinated biphenyls (PCB), Aroclor 1254, was administered ip (500 mg/kg) to pregnant Swiss noninbred CD-1 mice on the 19th day of gestation. The suckling offspring of these mice and of controls were then treated ip with 5 mg N-nitr

3-Hydroxyxanthine: transplacental effects and ontogeny of related sulfate metabolism in rats and mice

Autor: L M, Anderson, J J, McDonald, J M, Budinger, I M, Mountain, G B, Brown

Publikováno v: Journal of the National Cancer Institute. 61(6)

The ontogeny of sulfate metabolism related to the metabolic activation of the carcinogenic purine N-oxide 3-hydroxyxanthine (3-OH-X) was studied in noninbred Sprague-Dawley rats. Sulfotransferase activity toward 3-OH-X was detectable in most fetal li
