OBJECTIVE To determine whether women's global self-assessment of their knowledge about hormone replacement therapy (HRT) corresponds to their performance on an explicit knowledge test about HRT and to measure associations among knowledge, personal characteristics, decision conflict, and intention to use HRT. DESIGN Preintervention telephone survey of 156(More)
UNLABELLED Emergency response plans often call on health care providers to respond to the workplace outside of their normal working pattern. HYPOTHESIS Providers will report to work during a mass casualty emergency regardless of family duties, type of incident, or availability of treatment. METHODS Survey of emergency personnel needed to respond to a(More)
The pulmonary isozyme of rabbit angiotensin-converting enzyme (ACE) is encoded by an mRNA of about 5 kb. cDNA clones corresponding to different parts of this mRNA have been isolated and the complete nucleotide sequences of both the coding and non-coding regions of the mRNA have been determined. The encoded protein has 1309 residues with a 33 amino(More)
Beech bark disease (BBD) requires prior infestation of bark by an exotic scale insect, Cryptococcus fagisuga, to permit infection by one or more fungi, primarily Neonectria ditissima and Neonectria faginata. Previous studies in North America report a progression in which N. faginata replaces N. ditissima as the dominant pathogen in the BBD complex. To(More)
Caliciopsis canker is an emerging problem in Pinus growing regions of Eastern North America. The fungal disease caused by Caliciopsis pinea is associated with overstocked stands and poor sites, but few quantitative data are available. The objective of this study, therefore, was to assess the extent and severity of Caliciopsis canker and to explore(More)
Solar carbon monoxide spectra indicate the existence of a cool (less than 4000 kelvin) component to the solar chromosphere coexisting with the hot, bright gas at 6000 to 7000 kelvin. However, both the existence and the location of the cool component have been controversial. New high-resolution spectra show that carbon monoxide goes into emission just beyond(More)
Two models for thick target emission spectra, one using constant depth of Bremsstrahlung and one using continuous slowing-down of electrons and multiple thin targets, were used to predict filtered emission spectra at various angles with respect to the central axis. Integration of these spectra and comparison against measured heel effect gave excellent(More)
Despite use as constitutive protein standards to quantify mRNA, data are limited regarding alteration of cyclophilin or glyceraldehyde-3-phosphate dehydrogenase (G3PDH) in hypertension or angiotensin converting enzyme (ACE) inhibitor treatment. We assessed these standards in 6 month old Wistar-Kyoto rats (WKY, n = 16), compared to age-matched spontaneously(More)
Astronomical observations in Arizona recorded the passage of one, and possibly more, volcanic dust clouds between January and June 1982. On 15 May the increase in extinction in visible wavelengths at Tucson was more than 40 percent or 0.4 in optical depth. At Flagstaff, 325 kilometers north, the increase in extinction on the same day was 25 percent. A(More)
