There is a range of visual languages which express logical statements, for example Euler diagrams. The effective use of such languages relies on knowledge about whether a diagram is contradictory and whether reasoning can be performed to transform one diagram into another. It is also desirable to know the expressiveness of such languages. Knowing what a(More)
Although prostatic cancer is often viewed as an androgen-dependent malignancy, a number of other hormones including 1alpha, 25-dihydroxyvitamin D3 [1alpha,25(OH)2D3] are now recognized to modulate its growth and differentiated phenotype. Seven different continuous human prostatic carcinoma cell lines were examined for the presence of biologically active(More)
The LNCaP prostatic carcinoma cell line was examined for the presence of specific receptors for 1 alpha,25-dihydroxyvitamin D3 [1 alpha,25-(OH)2D3]. Whole cell binding studies identified approximately 2500 high-affinity (Kd = 1.4 x 10(-9) binding sites per cell. Competition studies revealed that these receptors are specific for the 1 alpha,25(OH)2(More)
An extremely wide range of radiation sensitivities is displayed by various bacterial genera; for example, Pseudomonas aeruginosa has an LD502 of about 1000 r (Goldblith et al., 1955), whereas Sarcina rubens has an LD,o in excess of 500,000 r (Kilburn, Bellamy, and Terni, 1958). It would seem that any explanation of the wide range of radiosensitivities(More)
