Decreased nocturnal plasma melatonin peak in patients with estrogen receptor positive breast cancer

Unknown authors · 1982

Researchers measured plasma melatonin concentrations over 24 hours in 20 women with clinical stage I or II breast cancer. In ten patients with estrogen receptor positive tumors, the nocturnal melatonin increase was much lower than in eight control subjects. A significant correlation was found between peak plasma melatonin concentration and tumor estrogen receptor concentration in 19 patients.

Melatonin inhibition and pinealectomy enhancement of 7,12-dimethylbenz(a)anthracene-induced mammary tumors in the rat

Unknown authors · 1981

Melatonin given daily for 90 days significantly reduced mammary tumor incidence from 79% in controls to 20% in treated rats. Pinealectomy at 20 days of age increased tumor incidence to 88% compared to 22% in controls. Melatonin partially reversed pinealectomy effects, reducing incidence from 87% to 63%. Plasma prolactin was significantly lower in melatonin-treated animals (27 ng/ml) versus vehicle-treated (65 ng/ml).

Epidemiologic Studies of Microwave Effects

Charlotte Silverman · 1980

The review describes two unpublished cohort studies: one of U.S. naval personnel occupationally exposed to radar, and another of American Embassy personnel in Moscow compared with employees at eight other Eastern European posts. Neither study found differential health risks associated with presumed microwave exposure, but both had significant limitations.

A temperature regulating circuit for experimental localized current field hyperthermia systems

Melvin A. Astrahan, F. W. George III · 1980

The authors present a temperature regulating circuit for experimental localized current field hyperthermia systems using general purpose components. The circuit uses a variable attenuator with a field effect transistor controlled by thermistor feedback to modulate radiofrequency power. The design was tested in both animal studies and patient treatment with excellent results.

MICROWAVE THERMOGRAPHY ; THE MODELING OF PROBES ; AN APPROACH TOWARD THERMAL PATTERN RECOGNITION

D.D. Nguyen et al. · 1980

They used an active process with a coherent microwave signal fed into tissues and a passive process estimating thermal noise power from tissues reaching the probe. They verified that probe-tissue matching improves when the permittivities of the probe dielectric and tissue are closer. Experiments with a polythene pipe filled with warm water in a water tank showed good agreement between computed and experimental thermal signatures.

MICROWAVE INDUCED HYPERTHERMIA – RADIOTHERAPY IN THE TREATMENT OF SUPERFICIAL HUMAN MALIGNANCIES

Harvey et al. · 1979

Researchers treated ten patients with superficial metastatic tumors using microwave hyperthermia at 2450 MHz. Hyperthermia was delivered at 43°C for 45 minutes using a dielectrically loaded tapered or conformal wave guide applicator. Heat alone produced one complete response, one partial response, and one minor response among the 10 patients. Five lesions that did not respond to heat alone were then treated with hyperthermia plus radiation therapy, resulting in three complete responses and two partial responses.

Biopsychological Studies of Microwave Irradiation

Charles L. Sheridan et al. · 1979

The longevity study of mice exposed in utero to near-lethal 2450-MHz microwave radiation is in its third year with mortality rising in both groups. Spontaneous tumors appeared in two control mice (n=81) but not in radiated mice (n=83), a difference too narrow to exclude chance. Acute studies in anesthetized rats, guinea pigs, and rabbits showed that brief near-lethal 2450-MHz exposures produced whole-body temperature rises of 4.5 to 12 K and altered thermal distributions, with the brain stem appearing thermally privileged. Twelve pilot studies were completed to optimize microwave hyperthermia as adjuvant treatment for experimentally induced glioblastoma in rats.

Simultaneous Microwave Local Heating and Microwave Thermography, Possible Clinical Applications

D.D. N'Guyen, A. Mamouni, Y. Leroy, E. Constant · 1979

A basic experiment showed the possibility of combining microwave local heating of subcutaneous living tissue with microwave radiometry using the same system. The system used a 4.6 GHz generator for heating and a 9.6 GHz radiometer with 60 MHz bandwidth for temperature measurement. In beef, 5 W of heating power produced an 8°C temperature increase in 10 minutes, and radiometric measurements agreed fairly with thermocouple readings. The authors suggested the method could help detect diseased tissue such as breast carcinoma, which becomes warmer than healthy tissue after microwave exposure.

Electrical wiring configurations and childhood cancer

Unknown authors · 1979

An excess of electrical wiring configurations suggestive of high current flow was noted near the homes of children who developed cancer compared to control children in Colorado during 1976-1977. The association was strongest for children who had lived their entire lives at the same address and appeared to be dose-related. The correlation did not appear to be explained by neighborhood, street congestion, social class, or family structure.
