Transfer of human chromosomes via human minisegregant cells into mouse cells and the quantitation of the expression of hypoxanthine phosphoribosyltransferase in the hybrids.
(J Cell Sci, 1978-04)
The behaviour of human cells arrested in mitosis can be severely perturbed so as to generate numerous small minisegregants containing very few chromosomes. These cells can be separated according to size and DNA content and ...
On measuring fuzziness: a comment on "A fuzzy set approach to modifiers and vagueness in natural language".
(Journal of experimental psychology. General, 1979-12)
Hersh and Caramazza's application of fuzzy set theory to vagueness in natural language is criticized for including in their measures of fuzziness response variability due to experimental and statistical procedures.
A halo visual illusion.
A visual illusion consisting of transparent halos extending beyond the boundaries of rotating discs is reported. The effect can be obtained by rotating a variety of black-and-white discs at moderate speeds. It is not due ...
A simple design for an impossible triangle.
Identification of beta-adrenergic receptors in human lymphocytes by (-) (3H) alprenolol binding.
(J Clin Invest, 1976-01)
Human lymphocytes are known to posessess a catecholamine-responsive adenylate cyclase which has typical beta-adrenergic specificity. To identify directly and to quantitate these beta-adenergic receptors in human lymphocytes, ...
