OBJECTIVE To determine whether interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-2, IL-4, interferon-gamma (IFN gamma), IL-6, and tumor necrosis factor alpha (TNF alpha) are detected more frequently in sera from scleroderma patients than in sera from controls. METHODS Serum concentrations of these cytokines were measured in 78 scleroderma patients and 73(More)
Two spectroradiometers, one based on a conventional prism monochromator and the other on a system employing narrow band pass interference filters, have been set up and independently used in the determination of the spectral irradiances of a number of sources over the wavelength range from 0.25 micro to 2.5 micro. Basically, the method of calibration for(More)
The National Bureau of Standards standard of total irradiance as presently issued in the form of a 50-W carbon filament lamp was originally calibrated more than fifty years ago. Recently, needs for higher accuracy and wider ranges of total irradiance have necessitated the setting up of three sizes (100 W, 500 W, and 1000 W) of tungsten-filament lamp(More)
