Abstract Previous studies in this laboratory and others have demonstrated both stimulation and inhibition of vasopressin release by norepinephrine. In other regions of the central nervous system, diverse effects of norepinephrine reflect activation of different types of adrenergic receptors and the interaction of norepinephrine with other regulatory(More)
BACKGROUND DNA tracts composed of only two bases are possible in six combinations: A+G (purines, R), C+T (pyrimidines, Y), G+T (Keto, K), A+C (Imino, M), A+T (Weak, W) and G+C (Strong, S). It is long known that all-pyrimidine tracts, complemented by all-purines tracts ("R.Y tracts"), are excessively present in analyzed DNA. We have previously shown that R.Y(More)
A program to map the locations and frequencies of DNA tracts composed of only two bases ('Binary DNA') is described. The program, TRACTS (URL and/or is of interest because long tracts composed of only two bases are highly over-represented in most genomes. In(More)
Structural modelling techniques are employed to explore the energetic requirements for the transformation of classical B DNA into unwound yet double-stranded DNA structures. Structural idealization using CORELS computer program of Sussman et al. followed by energy minimization using the EREF program of Levitt, leads to two regular non-helical models. In(More)
