Vasopressin and related peptides cause short-lasting hypothermia when injected into the lateral ventricle of the rat. In the present study, the structure-activity relationships for the induction of this effect were examined. For the agonist peptides studies, the structural requirements were found to be similar to those required to cause peripheral(More)
This paper describes two studies about the determinants of attitudes to pre-implantation genetic screening in a multicultural sample of medical students from the United States. Sample sizes were 292 in study 1 and 1464 in study 2. Attitudes were of an undifferentiated nature, but respondents did make a major distinction between use for disease prevention(More)
We tested 163 strains of fungi and bacteria for their ability to (−)-Δ1-(3R, 4R)-tetrahydrocannabinol (= Δ1-THC) in vivo. In the experiments 51 strains were found to be active and were further tested under varying conditions. The screening is described and the metabolites of Δ1-THC obtained from the incubations are characterized by their two-dimensional(More)
The neurohypophyseal hormones oxytocin and vasopressin cause a variety of biological effects in animals which are mediated by central nervous system mechanisms. Among the best studied of these effects is the modulation of both memory processes and the development of drug tolerance and dependence. Neurohypophyseal hormones have also been shown to alter(More)
The neurohypophyseal hormones oxytocin and vasopressin evoke characteristic behavioral changes after intracerebroventricular injection in mice. These included the induction of excessive grooming and scratching in an unrestricted environment and of escape behavior in stressful situations. The structure-activity relations of 33 neurohypophyseal hormones and(More)
Neurohypophyseal hormones and related peptides cause behavioural alterations after intracerebroventricular injection in mice. In the present study, these effects, consisting of excessive grooming and scratching, and of escape-directed activity in stressful situations, could easily be distinguished from those of other centrally acting peptides and drugs by(More)
